What's going to happen in the future? Will robots control our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen in 10 to 30 years from now, according to the BBC.2-1-c-n-j-y Digital money We used to pay with cash for everything we bought. Now when we use a credit card to shop online, money is spent without us seeing it. That means we are already using digital money. Using a card is much easier than searching our pockets for change. It is also safer than carrying a lot of cash. When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. It's reported that people in Sweden completely stopped using cash last year, and the US might be next. Bionic eye It's no longer something only in a science fiction movie. People who are blind may have a chance to get their sight back--by wearing bionic eyes. A blind eye can no longer sense light, but a bionic eye can use a camera to "see" the environment and send data to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A high resolution image could be just a few years away. Self-driving cars Unlike a human driver, a self-driving car won't get distracted by phone call, the radio or something outside the window. Sensors and cameras on the car would allow it to stick reduce the number of road accidents. You could even take a nap while the car driver itself. Many vehicle companies are now planning self!driving cars. "By 2040, driverless vehicles will be widely accepted and possibly be the dominant vehicles on the road," said Jeffrey Miller, professor at the University of Alaska Anchorage, US. Which of the following statements is TRUE?
|
[
"Bionic eyes only appear in the science fiction film.",
"Human drivers won't get distracted by something outside.",
"The blind wearing bionic eyes may see clearly in the future.",
"There will be no road accidents at all if self-driving cars are used."

Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It's an increasingly urgent question, given the recent mining accidents in Sago. W. Va. and Huntington, Utah. A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work. Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners--the special operations of the mining industry. One of the first mining robots was developed five years ago at Canegie-Mellon University's Robotics Institute. It was called Groundhog. It used lasers to "see" in dark tunnels and map abandoned mines - some of the most dangerous work in the business The latest design is called Cave Crawler. It's a bit smaller than Grondhog, and even more advanced. It can take photos and video and has more sensors that can discover the presence of dangerous gases. The robot has a real sense of logic, which is hard to believe. If it comes across a thing in the way it gets confused. It has to think through the process and where to go next, and sometimes it _ just like a real person. The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money has dried up, and it's not clear where future money will come from. Partly for that reason, and partly because of advances in safely, mining is not nearly as dangerous as it was in the past. Since 1990,fatalities have declined by 67 percent and injuries by 51 percent, according to the National Mining Association. Some experts predict that robots in the mines will serve much of the same function that they do in the automotive industry. The robot do the most boring and dangerous jobs, but don't eliminate the need for human workers. What can be the best title for the text?

Animals grow up in different ways. They have lots of lessons to learn. Some animals are born helpless but their mothers protect them. A newborn kangaroo is the size of a bee. She stays in her mother's safe pouch. She doesn't open her eyes for at least five months. A newborn monkey cannot walk. He is carried by his mother. Other baby animals can walk soon after they're born. They learn to run with their mother when danger is near. A baby zebra can run an hour after she is born. Some baby animals are born in a place that is safe. Other baby animals are born in the open. Baby wolves are born in large holes. A baby elephant is born on open, grassy land. Other elephants make a circle to protect her. Animals that drink their mothers' milk are called mammals. A mother bear's milk is fatty and rich. Baby bears need lots of fat to keep warm in winter. They have milk for six months. Baby zebras drink milk for six months or more! As baby animals grow they need solid food. Baby lions eat what their mother can catch. What can't a baby zebra do an hour after she is born?

You may never think a documentary film could have aroused so much public enthusiasm in Chinese history. Nowadays everybody is talking about a new 7-part documentary called A Bite of China which was recently broadcast late at night on CCTV I. The documentary describes various _ across the vast Chinese culinary landscape. According to Taobao, China's biggest online retail website, just five days after the series began to air, nearly 6 million people went to the site in search of various local specialties, particularly those mentioned in the documentary. More than 7.2 million deals were concluded. A ham producer from Yunnan Province saw his sales grow 17-fold in five days. However, one can't help but believe that the documentary's popularity is probably linked to the endless stream of terrible food security issues that have emerged in recent years. In one well-received article, a netizen wrote, "I wonder how many felt so empty-hearted and sighed after watching the film. Blue-vitriol watered chive, formaldehyde sprayed cabbage, Sudan Red colored salty eggs, restaurants using gutter oil. The list is long..." How will a varied and ancient food culture that is famous worldwide and which should have made the Chinese proud end? Food is the most vital thing in people's lives. Yet China's food industry has made people a little worried due to some severe food safety crisis. The market is huge while the cost of faking and cheating is so low for immoral businessmen; and the punishment is too light. Take the milk industry as an example. Although Sanlu, the company that sold the melamine-adulterated milk powder, was punished, thousands of other dairies didn't work hard to improve the quality. Therefore, food safety problems should be an important concern of Chinese government so that our ancient food culture can be preserved. As the documentary shows, people are attracted not to gourmet items like matsutake, a species of rare mushroom grown naturally in remote forests, but to common Chinese dishes like barley, lotus root or tofu. They are what meet our basic needs. This explains why people are so excited about A Bite of China---it is a reminder that there is still a world out there where food is excellent and safe. According to the passage, China's food industry has a problem of faking and cheating because _ .

Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived . Biological death occurs when changes in the organism lead to the "breaking up" of vital cells and tissues. Death is then unchangeable and final. Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism , cooling delays the processes leading to biological death. To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta's heart became active once more. After fifteen minutes, spontaneous breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal.

Sitting at a desk in a classroom all day can be pretty boring. The teachers at Ward Elementary in Winston -Salem,North Carolina ,picked up on that and traded in their students' desks for exercise bikes as a part of their Read and Ride program! The Read and Ride program began five years ago.One classroom has enough bikes for every student in any given class,and throughout the day teachers bring in their students to the room to ride them and read their books. Even regular classrooms have one bike in the back of each room for students who just can't sit still to use to help them burn energy in a good way. Students love being more active! Teachers enjoy seeing students eager to read.Parents appreciate stronger,smarter children.Headmasters value this effective and cost-free program."Riding exercise bikes makes reading fun for many kids who get frustrated when they read.Thus,they have a way to release that frustration while they ride,"said Scott Ertl,who started the program."As we can see,everyone wants to promote literacy and lose weight! But many students who are overweight struggle with sports and activities since they don't want to always be the last or lose with others watching on the playground.On exercise bikes,however,students are able to exert themselves at their own level--without anyone noticing when they slow down or take a break." As it turns out,not only are the bikes helping the students burn calories,they're also helping them learn better and stay focused.At the end of the school year the school analyzed testing data and found that students that spent more time reading and riding did more than twice as well on reading tests than their fellow students who spent the least time in the program. Why did the teachers start the Read and Ride program?

How could we live without the Internet? That's how most of us keep in touch with friends, find homework support, research cool place to visit, or find out the latest news. You can use it to do research for school, find out what movie is on near you, check out a college you're thinking about, or find a job or volunteer opportunity. Almost anything you can think of has a website about it. You've probably heard stories about people who get into trouble in chat rooms. Because users can easily _ , you may be cheated in the chat room. Everyone in the chat room looks like wearing a mask . Chat rooms often attract people who are interested in more than just chatting. They will sometimes ask visitors for information about themselves. The information might be about their families, or where they live. It shouldn't be given away. Usually, the people who request personal information like home addresses, phone numbers, and email addresses use the information to do some illegal things. This might harm a person's or family's well-being. Of course, the Internet is home to millions of places you can and should visit. However, remember to protect yourself while online.

In October on the east coast of Australia migrating humpback whales pass very close to the shore. With the help of Max Egan, we went to film them near Byron Bay. It was extremely exciting to spot the little puffs of spray on the horizon. When migrating, the whales can be traveling at speeds of about 12km/h and can dive under anywhere between five and forty minutes, but with many years of experience Max usually guided our boat to exactly the right place to provide us with amazing sighting. As the whales break the surface like submarines , the water spills off their broad dark backs and huge tails. Then, with a powerful down stroke, they dive back into the depths of the sea, leaving just a smooth glassy patch of water or "footprint" on the surface to show where they had been. One day we had traveled up and down the shore and far out to the sea in search of whales, but the horizon was deserted. There was no report of whales in the area so we decided to test out Max's new, highly sensitive hydrophone and the result was astonishing. As soon as the hydrophone was in the water, we found ourselves listening to the most beautiful voices. What may have seemed like a vast empty ocean was filled with the singing of whales. It is the males which sing, as they migrate between feeding and breeding grounds. No one knows for sure what the purpose of these songs is, whether they are love songs to the females or warnings to other males to stay away. It was thought that each population of humpbacks had its own song which remained regular but recent findings suggest that the whales appreciate a memorable tune and quickly adopt any new songs they hear. What do we know about Max?

It has become a certain belief among the public-drink at least eight glasses of water a day to improve health and well--being.Bottled water companies often repeat it to increase their sales but it is actually a silly idea. There is no evidence to prove the advantages of drinking eight glasses of water a day,scientists say. The misunderstanding is caused from the suggestion that adults should drink 2.5 liters of water daily,which was highlighted(,)by the British Medical Journal in December.The important part of the suggestion that most of this quantity of water is contained in prepared foods,however,is usually ignored. U.S.researchers who reviewed the evidence concluded that most people do not need to worry about the amount of water they drink every day.Besides drinking water,they will be getting plenty of liquid in other ways.Caffeinated drinks such as tea,coffee and cola,and alcohol can help reach the daily total if they don't drink too much,though these drinks help the production of urine . Less well known are the dangers of drinking too much water,causing water poisoning,low salt levels and even death. The review of research by Dan Negoianu,from the University of Pennsylvania,found that not a single study included the suggestion of drinking eight glasses of water a day.Although one small study suggested that drinking water could result in fewer headaches,the results were not very important.However,the benefits of drinking some water to prevent a pain in head after drinking too much alcohol are.separately,proved to be true. No studies showed any advantages to the color1 of the skin because of the increased water taken into bodies.Dehydration can make skin less pleasant,but there was no clear evidence to support the idea that water helps people keep a youthful appearance.The researchers also found no evidence that drinking lots of water does some good to the body's organs .

More than a hundred adults and kids gather for the Star Party on a cold evening, chattering excitedly as they stand in the dark on a Virginia hillside. The odd thing is, no one has turned on a flashlight, and no streetlights or house lights wink on around them. These people have traveled to the countryside more than an hour from Washington, D. C., to get away from the glow of city lights. That's because they are attending a star party. Star parties are gatherings where professional and amateur astronomers set up their telescopes and invite people to come learn about the night sky. Getting away from light pollution, or artificial skylight from buildings for example, helps stargazers see objects in the sky much better. At this star party, Sean O'Brien of the National Air and Space Museum's Einstein Planetarium starts off by asking the crowd to simply look up and take in all they can see. He points out plenty of things that can be seen without special equipment. Stars, satellites, and even the Andromeda galaxy can be found if you know where to look. After that, several dozen astronomers offer close-up views. Each has focused their telescope on a different part of the sky. As kids take a look, the owner gives a mini-lesson. O'Brien says you can have your own star party at home and learn a lot just by paying attention to what's happening up above. "Watch the sky as the seasons pass, and you will see that it changes," he says. "Or start with the moon. Notice when and where you are seeing it--maybe even in the early morning while you wait for the school bus. " Which of the following can be best describe what O'Brien says about discovering the stars'?

Millions of American kids come home to or leave an empty house every day. However, parents are increasingly using an existing technology -- home security systems -- to keep an eye on their "home-alone" children. In the early days of home security, the systems were basically designed just to keep the bad guys out. Now, many parents are also using them to make their children safe when they are at home alone. Below are some simple rules for adults to teach their children: Every child should memorize his or her own full name and address, and home, work and cellphone numbers of each parent. Also keep this information posted next to the phone at home. If your child is too young to memorize the information, he or she may be too young to be home alone -- for any time. Teach your child to observe things around him or her when he or she returns to the house. If a door or window is slightly open, the child has any reason to suspect someone has been in the house that shouldn't be, have him or her call you, then wait at a safe house a neighbor offers. Warn your child never to answer the doorbell or telephone when they are home alone. Besides, set a rule that he or she must never play outside the house when no one else is at home. Be sure he or she knows how to disarm and arm your home security system. Program your control panel to give you a message when your child enters or leaves the house, and arms or disarms the system. If your child forgets to rearm the system, you can call him or her with a personal reminder. To learn more about home security systems that can help parents protect their "home-alone" children, visit www.ProtectAmerica.com. According to the passage, home security systems _ .

When Steven was a young boy, he moved quite often with his family and so he never had many friends. He spent a lot of time on his own and liked to play with electronic things. Steven had a neighbour, Steve Wozniak. Steve was a little bit younger than Steven but also liked to play with electronic things. Steven made a microphone and Steve asked him many questions about it until he understood how it worked. Steven liked the fact that such a young boy was also interest ed in electronic things and so he taught him everything he knew. When they were a little older and knew more about electronic things, they made a "blue box". People could make free phone calls by breaking into the phone company's system with this box. They sold this to many people even though it was illegal , but this is not why they are famous today. Steven and Steve were the inventors of the first PC--personal computer. They called their first computer the Apple I. They invented it only for fun and to make themselves known among their friends. They did not think it would become so popular. They just liked playing computer games on it. Their computer made it cheaper and easier for people to own and use a computer. Their PCs were so popular that they made a new PC called the Apple II. Soon many schools, families and factories were using their computers. Without the two clever men, the personal computers might never have appeared. Why didn't Steven have many friends?

People have always wanted to speak with animals. There are many books about this, especially children books. Now there are also movies, such as Dr. Doolittle. When you watch animals, it seems clear that they can communicate with each other. Many people wonder why people can't also communicate with them. Scientists know how some animals communicate. Bees, for example, use their bodies. They do a kind of dance to give information about food. Birds, on the other hand, share information with sounds. They use certain sounds to protect their homes and to stay together when they fly. Some male birds use lovely songs to attract a female . Other animals communicate with both body movements and sounds. For example, dogs wag their tails when they are happy, and they bark when they are excited. People used to think it was possible to teach human language to animals. Parrots and other birds, for example, can learn to say words. But the birds just repeat the words. They don't understand them. Some American scientists tried to teach English to chimpanzees , close s of human beings. However, this was impossible. Chimpanzees can't move their mouths the right way. They could never learn to speak like people. Then scientists tried to teach human language to chimpanzees in other ways. Some tried with American Sign Language (ASL). Others tried with a simple computer. But chimpanzees could only learn to use a few words. They could never learn to use grammar. Their brains are very different from the brains of human beings. Now some scientists are studying the same points between human and animal language. In fact, some animals use sounds like people do. Dogs, for example, use an unpleasant, low sound to tell other dogs to stay away. People, too, use that kind of voice to say the same things. A dog's noisy bark communicate that something is happening. People use the same high tone when they shout, "Watch out!" Scientists want to understand the language of other animals, such as whales and bears. To do this, they go out to the animals' natural homes. They watch the animals for days or even years. They take pictures and make tape recordings and share the information with other scientists. In this way, they hope to learn more about the way animals communicate, and maybe someday we'll be able to communicate better with them. Which of the following is TRUE?

The strong emphasis on educational achievement in China, Japan and other parts of South-East Asia may be coming at a heavy price. Researchers say that hard work at school plus the lack of exposure to outdoor light is damaging the eyes of almost nine out of ten students--with one in five at serious risk of visual impairment and blindness. The scientists say that young people need up to three hours a day of outdoor light, but many infants are also missing out as they nap during lunch time. Dr. Ian Morgan is the lead author of the study. "I think what's happened in South-East Asia is that we've got _ . We've got the massive educational pressures and we've got the construction of a child's day in a way that really minimises the amount of time they spend outside in bright light." The scientists say that genetic factors, long thought to play a big role in short-sightedness, are not as important as the environment. They point to Singapore as a place with several different racial groups, all of whom are now suffering high levels of short-sightedness. The authors suggest that compulsory time outdoors should be considered by educational authorities across South-East Asia as a way of dealing with the problem. The authors strongly believe that _ .

London has a new magazine. But it's not printed on paper. Everyone who has a television can receive it because it is on TV. In order to read this magazine you have to have a _ . Each page of it is numbered, so you only have to dial the number to choose which subject you want to read about. There's a wide choice--- everything is included from cooking to the latest sports news. If you want to read the news, the first thing you have to do is to turn to the index page which has an easy-to-remember page number, 100 for example. Then you start choosing what you want to read. The news is on pages 101 to 109, so you push out the numbers and the news appears written across your screen. Perhaps you want to go out in the afternoon, so you press 181, and a brightly colored weather map appears on the screen. But the weather is terrible so you decide to go shopping and dial 162 for a list of the week's best bargains. But should you drive or take the train ? To answer the question you only have to press 189 for the traffic report. It's very simple to use. But probably the best thing about the service is that it's being updated all the time. Journalists type new material directly onto the screen and whole pages of the magazine can be replaced in minutes. London has already had three services. One, transmitted by ITV, is called ORACLE, while the other two, on BBC, are called CEEFAX, because they let you see facts. Although CEEFAX and ORACLE have been operating for some time, they have not been well publicized. BBC engineers do not think that their idea will ever replace books and newspapers because they can be taken with you everywhere. But many people agree that this is a breakthrough as great as the invention of printing, which could change not just our reading habits but our whole way of life. The passage is mainly about _ .

At a primary school in a small town in the east of South Carolina, second-grade teachers Carneau and Lynne are convinced that separating primary boys and girls produces immediate academic improvement in both genders David Chadwell, South Carolina's coordinator of single gender education says, " Boys and girls learn,hear and respond to their surroundings differently. We can teach boys and girls based on what we now know." Male and female eyes are not organized in the same way,he explains. The composition of the male eye makes it sensitive to motion and direction. " Boys interpret the world as objects moving through space," he says. The male eye is also drawn to cooler color1s like silver and black. It's no accident that boys tend to create pictures of moving objects instead of drawing the happy color1ful family,as girls do in class. The female eye,on the other hand,is drawn to warmer color1s like red, yellow and orange. To attract girls, Chadwell says, the teacher doesn't need to move as much as in boys' class. Using descriptive phrases and lots of color1s in presentations or on the blackboard gets their attention. Boys and girls also hear differently. " When someone speaks in a loud tone,girls interpret it as yelling, " says Chadwell. " They think you're mad and can shut down. " Girls are more sensitive to sounds. He advises girls' teachers to watch the tone of their voices. Boys' teachers should sound more forceful, even excited. A boy's nervous system causes him to be more cautious when he is standing, moving, and the room temperature is around 6.Stress in boys,he says, tends to increase blood flow to their brains, a process that helps them stay focused. Girls are more focused when they are seated in a warmer room around 75degF. Girls also respond to stress differently. When exposed to threat and conflict, blood goes to their guts ,leaving them feeling nervous or anxious. These differences can be applied in the classroom, Chadwell adds. " Single gender programs are about maximizing the learning." Which of the students is most likely to stay focused?

We had one class for computers when I was in school, which was also introduced new in school and all the students did not attend it. I took it because I had free period and was interested in taking it. In those days we could not image that computers will become so important in our lives otherwise most of the students would have joined the computer class. Computers are beneficial for almost anyone and the present generation is growing in an atmosphere where you need the computers for doing almost everything .If they are not made computer literate they will lag behind in all the activities. Nowadays almost all schools have some kind of computer courses for the students so that they learn the fundamentals of the computer. It will not be possible to do it if they don't have computer classes. Most of the homes have personal computers now and most children are already aware of the basics before they join school. Computing courses are also good for adults who are not familiar with the computer as most of the jobs which are available today have the use of computer in some way or the other. Adults who have not used the computer before are generally quite anxious, but an easy computing course will be able to change the way they think in a few weeks. If you are interested, you can join a computing course which is longer and teaches you more than the basics, but you may have to spend more time in the completing course. They are very useful courses as _ teaches you ways to use the fundamental programs which are typically used in various jobs. It is also possible you may like to do the computing course for enjoyment as some of the classes are also free .There are courses which charge a fee for skills like graphic design and photo editing . They are a lot of fun too and may also be useful when you do a job , depending on the kind of career ,someone you choose or have . You will find these courses in the colleges, as well as online, if you already are familiar with the use of computer. Most of the students didn't attend the computer course probably because _ .

Is it wrong to use someone else's wireless(Wi-Fi) connection?Just recently,a man was arrested for doing just that.At that time,he was sitting in the street with a laptop and using an unsecured wireless connection to surf the Net.What do you think about this topic?Listen to the following different views on it. For a start,if someone is using your Internet service or downloading,this will affect your speed of access or download limit.Also,it's bad for Internet service providers.They will suffer in the long run because fewer people will pay for an Internet service if they know they can get it for free.And finally,just imagine this:what if the person who is stealing your Internet connection is involved in an illegal activity?I think the police are totally right to arrest these criminals. --by Sandra Wilkins Basically,if the person who paid for the service still has everything they paid for,what's the problem?It's just like using the light from streetlamps to read your book,or watching someone else's firework display.It's not stealing. Also,if you leave your wireless connection unsecured,then it is your own fault if someone else uses it.Just as you wouldn't leave your front door unlocked,or your car door open,neither should you leave your wireless connection open.By leaving your wireless connection open,you are inviting people to use it.Securing your wireless connection is as easy as clicking a few settings on your router .And finally,haven't the police got more important crimes to solve?They're always saying how they haven't got the manpower to solve real issues.But this is just ridiculous . --by James Hoarley What would be the best title for the passage?

"Any time! Any where! Decades ago there was no such thing" - "Communication". Then, September 7th 1987, the global system for mobile communication or GSM was born. And international agreements that laid out the standards, regulations and practices gave rise to a global mobile phone industry. To be honest, the world's first mobiles were not so attractive and the range of effectiveness wasn't very good. But they became a must-have among those wealthy people who could afford that. However, by advantage of GSM which has many different elements to it, we can all enjoy the ability to go around the world in 217 countries, land in that country and know that a phone would work. There are other cell phone systems using different technology in the world. The majority of the United States and parts of South America have been using something called CDMA which is very rare in Europe. In some Asian countries like China, GSM and CDMA both exist at the same time. But the GSM Association claims 85% of the global mobile phone market. They estimated there are now about 2.5 billion different users who make more than 7 trillion minutes of calls everyday, and that's not all. 20 years later, the mobile phone is so much more than just a phone. You can use it to send text messages, take pictures, show video, even surf the internet. "The phone itself is involved from just being a communication tool, to be a tool for round-the-clock connectivity, you can not live without it even in a minute." Mobile consultant Nick Lane also points out with so many customized styles and features, your mobile phone will become a symbol of you. Where will the global mobile phone industry be in another 20 years? Certainly, there will be more connections than better coverage. As for where else technology will take us, one can only imagine. According the passage, we can know that GSM is _ .

Australian sleep researchers have developed a set of hi-tech "sunglasses", described as the world's first "time control" glasses, which can imitate sunlight patterns. The team, from Flinders University, in Adelaide, says the glasses send out a soft green glow that helps a traveller adapt to changing sleep patterns and time zones in "small steps". It targets a part of the brain that regulates the human body-clock, by sending signals to the rest of the body that help it slowly realise it is in a different area of the world. It has been suggested the device, called the "Re-Timer", is currently the only wearable body clock adjustment system commercially available. Scientists say the device, officially launched in South Australia, can help ridf the negative effects of long-timel travel and bring new relief to insomnia sufferers, shift workers and even teenagers. "The light from Re-Timer stimulates the part of the brain responsible for regulating the 24-hour body clock," said Prof Leon Lack, its chief inventor. Extensive research has shown that green light is one of the most effective wavelengths for influencing the body clock. The battery-powered device, which retail for PS162 in Britain, then sends signals that cause the production of hormones and daily cycles known as circadian rhythms . Those people who want to sleep peacefully, but wake earlier, should wear it for 50 minutes in the morning for three days. Those who want a lie- in, should wear it for the same time before bed to delay the body clock. The device, which is powered by an inbuilt rechargeable battery, can also be worn as sunglasses during daily tasks such as reading or using a computer. "The glasses have been designed to be user friendly and comfortable to wear so people can go about their normal activities wearing them at work or at home," he said, adding they had been designed based on 25 years of university research. It is estimated that up to 94 per cent of long-time travellers suffer from jet lag because the body becomes confused to travelling through different time zones. So the glasses are good news to them. It uses the outside world as indicators as to whether it should be awake or asleep including factors such as light, silence or noise. Airlines are said to be seeking a "silver bullet" for the tiredness and confusion that often follow a long-timel flight and are in discussions to buy the device. If you wear a "Re-Timer" an hour before bed, you will probably _ .

Although we already know a great deal about flu, and although the World Health Organizations is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be. There are three kinds of flu virus, known as A, B and C. flu C virus is ly stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability is less developed in the flu B virus, which affects only human beings. As flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918&1919, when about half the world's population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence , the ease with which it can be transmitted and the strength of the opposition it encounters . Scientists, however, have a reliable general picture of the world situation. This article is quite probably _ .

We've all heard the quote, 'Be kind, for everyone you meet is fighting a hard battle.' My husband and son died within two years of each other. From my personal experience, I believe that if we aren't careful, grief can become a rather self-involved process in which we can become so focused on our own suffering that we miss the opportunity to connect with, and possibly bring comfort to, someone else who may be going through a similar experience. Six months after my husband died, I was sinking in the quicksand of grief. I could not pull myself out of the misery. In that moment, I actually believed that my life was more difficult than anyone else around me. Life handed me a perfectly wrapped lesson that opened my eyes to the fact that through my suffering I had allowed myself to become blinded by my self-pity. The lesson presented itself in a health crisis. I had complications from a surgical procedure and ended up being hospitalized for four days. I was in an extreme amount of pain during this time. Between the physical pain and the emotional pain of grief, I was an mess. I should also tell you that I am a Registered Nurse. As a nurse, it is hard to be on the receiving end of medicine as the patient. The first three nights that I was in the hospital, the same nurse took care of me. She was young, maybe in her mid to late 20s, and she hardly interacted with me at all the first two nights, other than to give my medications as scheduled. She obviously had no idea how much emotional pain I was in. How hard is it to ask your patient how she's feeling? I wrote her off as a bad nurse who had little sympathy, and remained absorbed in my own emotional and physical pain. The third night the young nurse was a little more talkative. She asked me how I was feeling (finally!). I told her that I was struggling with depression and grief because my husband had died in an airplane accident. She looked at me and told me that her husband had died too, just two months earlier. I was stunned. Speechless. Shocked. Never, in any of the possibilities that my mind entertained of why this nurse was so unfriendly to me, did I even consider that she might be in the same pain I was. Not only was she grieving as I was, but she was having to take care of me, instead of caring for herself and her family. We went on to talk and share our stories about our late husbands and children. I like to think that we helped each other a bit that night. We had much more in common than I would have believed. We were both widowed single moms with young children, and nurses. But, that was where the similarities ended. Her husband had no insurance policy. She had very little family support. She was working paycheck to paycheck to support her boys. I was humbled. I realized how much I had to be grateful for. And, frankly, I never saw life the same way after this experience. This experience was a life-changing event for me. I had always prided myself on being a sympathetic person, but I realize now that I had not really understood what being sympathetic meant. To truly be sympathetic, you must be able to see beyond your own pain to be witness to the pain. I never looked at another person in the same way after this experience. I thank death for very few things. The gift of sympathy for my fellow man, and understanding that we all suffer in ways that aren't always visible, are presents from death that I will always be grateful for. Always take the time to be kind even when you're suffering with your own pain. And don't assume that someone else has it easier than you. You never know the battles someone else is fighting. Why did the author regard the nurse as a bad one at first?

Only about 30 percent of people in the US know how to perform CPR . Recently, a 9-year-old boy showed a Georgia woman how to perform CPR on her newborn baby. Susanna Rohm said she had experienced a parent's worst nightmare -- her 2-month-old son, Isiah, was not breathing. "I noticed he looked pale. I looked at his arms and his legs and they were limp ," Rohm told a local newspaper. "Then I noticed that he looked like he wasn't alive." In _ , she dropped and broke her cellphone. Rohm had to run into the street, screaming for help. "I had him in my arms and screamed over and over. Then I ran outside. I saw two boys playing across the street, and I yelled, 'Go and ask your parents to call 911,'" Rohm said. But the two boys were able to do more than that. Nine-year-old Ethan Wilson took action, showing Rohm how to perform CPR on little Isiah while ten-year-old Rocky Hurt helped as well. Rocky said he had learned the CPR technique from a poster in a health class at their school, Sedalia Park Elementary. "I was thinking we'd better give her a helping hand instead of getting scared," Ethan said. "I told her to push on the baby's chest five to ten times a minute with only two fingers, tilt back the baby's head, plug the baby's nose and breathe into the baby's mouth," Ethan said in an interview. At last, Isiah began crying and was breathing again. He spent two nights in a local hospital. "If the little boy hadn't shown me what to do right there, my baby would probably not be alive right now," Rohm said. What did Rohm do when she saw the two boys?

Students learn many subjects at school, like Chinese, English, math and physics. Some students think it's hard to do well in math. They say it's boring. Why do they say this? First, some math problems are so hard for them. They spend a lot of time on them, but they can't work them out, so they lost heart . Second, they are afraid( ) to ask their teachers for help. They think the teachers will laugh at them. Third, they think math class is very tiring because they need to use their brain to find out the answers all the time. How can you do well in math? Here is some advice from a math teacher: 1. Listen to the teacher carefully in class and do some extra exercises after class. 2. Ask the teacher for help if you don't understand anything. Don't be afraid. 3. Don't forget to go over your old lessons. If you do these things, you will find it much easier to do better in math. The advice is from _ .

Donna Ashlock, a 14-year-old girl from California, was very sick. She had a bad heart. "Donna needs a new heart," her doctor said, "she must have a new heart, or she will die soon." Felipe Carza, 15, was worried about Donna. Felipe was Donna's friend. He liked Donna very much. He liked her freckles, and he liked her smile. Felipe didn't want Donna to die. Felipe talked to his mother about Donna. "I am going to die," Felipe told his mother, "and I am going to give my heat to Donna." Felipe's mother didn't pay much attention to Felipe. "Felipe is just kidding," she thought, "Felipe is not going to die. He's strong and healthy." But Felipe was not healthy. He had terrible headaches sometimes. "my head hurts," he often told his friends. Felipe never told his parents about his headaches. One morning Felipe woke up with a sharp pain in his head. He was dizzy , and he couldn't breathe. His parents rushed Felipe to the hospital. Doctors at the hospital had terrible news for them. "Felipe' s brain is dead," the doctors said, "we can't save him." The parents were very sad. But they remembered Felipe's words. "Felipe wanted to give his heart to Donna," they told the doctors. The doctors did several tests. Then they told the parents, "we can give Felipe's heart to Donna." The doctors took out Felipe's heart and rushed the heart to Donna. Other doctors took out Donna's heart and put Felipe's heart in her chest. In a short time the heart began to beat. The operation was a success. Felipe's heart was beating in Donna's chest, but Donna didn't know it. Her parents and doctors didn't tell her. They waited until she was stronger; then they told her about Felipe. "I feel very sad," Donna said, "but I am thankful to Felipe." Three months later the operation Donna went back to school. She has to have regular checkups, and she has to take medicine every day. But she is living a normal life. Felipe's brother John says, "Every time we see Donna, we think of Felipe. She has Felipe's heart in her. That gives us great peace."

Do you know that a fast reader can get the ideas better than a slow reader can? Of course, you save time by reading fast, but this is not the main reason for fast reading. The main reason is that you understand better what you are reading when you read fast. As your eyes move along the line of point, they make fixations or pauses . It is important that you see several words at a fixation. It is also important that your eyes leave a group. The numbers of letters or words that you see at a fixation are called your eye span . Pay more attention to improving your rate of reading. With practice you can learn to read faster than you usually read. The way in which you read always depends on what you are reading and for what purpose. You should know the different ways of reading so that you can apply whatever method is necessary. Here are four ways of reading: (1) Skimming is an important kind of reading. This method can be used when you wish to review something that you have forgotten. You can skim to get the main points. (2) Rapid first reading and then rereading certain parts carefully is important. You may use this type of reading to study a science lesson or a history lesson. (3) You need to do careful reading and rereading sometimes. This type of reading is necessary for making an intensive study of your school subjects, solving math problems or reading directions. (4) Rapid reading is used when reading stories for enjoyment. You may also do rapid reading when reviewing materials that you already know well. Careful reading is an important kind of reading _ .

Shree Bose is one of the most impressive kids graduating from Fort Worth Country Day High School this year. Bose has a large circle of friends, and there's one who you may have heard of: President Obama. He has twice publicly recognized her achievements in cancer research and spoken with her in the Oval Office. If that isn't enough, Bose recently gave a TED Talk about her work with the cancer drug Cisplatin, which also won her first prize at the Google Science Fair and recognition as one of Glamour magazine's Young Amazing Women of the Year. After watching her grandfather struggle with liver cancer, Bose was determined to help out in any way she could. As a high school student though, her scientific choices were limited. She reached out to various hospitals and research centers, but doctors turned down her requests because they felt she was too inexperienced medically. Only the North Texas Science Health Center respected her determination and chose to guide her. The results were amazing. Bose chose to study a protein and its reaction with the cancer drug Cisplatin. She noticed that when she prevented this protein from growing, Cisplatin was allowed to begin destroying cancer cells once again. "My project not only contributes to the understanding of the relationship between the protein and Cisplatin, but also suggests a newer, more effective treatment for patients who resist Cisplatin," Bose said. Bose's achievements aren't limited to the lab, though. She was also captain of her swim team and editor-in-chief of her school paper. Bose is currently getting practical experience at the National Institute of Health and she'll be attending Harvard in the fall. She plans to study molecular biology and go to medical school. Eventually, she would like to be a doctor. From the passage, we know that _ .

Computers are good tools .The Internet is also good. But some people spend too much time online. They can't stop. Doctors say this is a new sickness. They call this sickness Internet Addiction Disorder (IAD). People with IAD are online a lot. They spend hours chatting to their friends or playing online games. Many people with IAD spend more time on the Internet than with family or friends. Some people with IAD even quit their jobs! Do you have IAD? Think about these questions:How many hours a day are you online? Is it a lot or a little? When you are not online,are you thinking about playing a computer game or checking your messages? When you are online,do you forget the time? Do you get angry when you can't play a game? If you have IAD,what can you do? Dr. Ivan Goldberg and Dr. Kimberly S.Young have some ideas. First,ask yourself "Why am I online a lot?" Then try to take a break. For example,use the computer or play games twice a week,not every day. In this way,you can have a good social life with other friends. Ivan Goldberg and Kimberly S. Young _

Recovery from bulimia is difficult,but a beautiful journey!You'll come across many challenges--but once you've beaten them,the world will look much more beautiful. You can recover from this illness--I promise!Remember:If I recovered--you can too! I began throwing up when I was just a kid. Back then I didn't know why I did that. But now I can see that it was the result of my seeking so called fashionable diets. I was only 8 years old when my aunty phoned my mom saying that I'd thrown up my dinner.I told them it was just a party trick,and they ignored it. Their reaction made me realize that this "trick" of mine should be a secret. I would continue doing it,but would never let anyone know. As I got older,this secret habit got more and more serious,and this carried on for years. During my first year of university,at the age of 20,I wasted over $20,000 on food from the school dining hall. Finally,after having had bulimia for nearly 12 years,I decided enough was enough. I was close to death--I could feel it in every part of my body. I needed help,and I made an appointment with a counselor of my university. One year later,I graduated from university. I was proud of myself for getting my degree. But there was a deeper pride and strength inside my mind. I had beaten bulimia. It had been a long and difficult road--but I'd done it. What might cause the writer's bulimia according to the text?

The oil from palms has a wide variety of uses and is found in food, soaps and shampoos. An international team found a gene that made some of the trees produce more oil than others. Dr Rajinder Singh, from government agency the Malaysian Palm Oil Board, said, "The oil palm has three fruit forms: a thick-shelled type --the Dura; those that don't have any shell--the Pisifera; a third form produced as a cross between the thick shell and the one without the shell--the Tenera, which are more of the fleshy fruit to produce the oil," and the researchers identified the gene producing this trait. While oil palm growers attempt to grow only the thin-shelled Tenera variety, up to 10% of the seeds can be contaminated , and turn out to be the other less oily plants. Prof. Martienssen, from the Cold Spring Harbour Laboratory, said, "We can now use that gene in genetic testing, which will allow growers as well as producers to know exactly what sort of tree they are planting before it produces fruit. It takes a long time for these trees to produce fruit, but by being able to predict exactly what sort of fruit that trees will produce, it will greatly assist growers." The researchers say this could offer a more sustainable form of agriculture. Prof. Martienssen said, "This finding gives us huge hope. We hope to maximize land usage and produce a lot more on the same amount of land, because we do not want to destroy the rainforest any more." However, the environmental group WWF-UK said that the global demand for oil palm was growing rapidly, making the expansion of plantations inevitable. Adam Harrison, the organization's food and agriculture policy officer, said, "In a sense it does not matter if a 'good' variety replaces forest or a 'bad' one, the wildlife and communities that need access to that land will suffer. So for palm oil to be sustainable, the process of allocating land needs to be controlled. There is an abundance of low-carbon, low-wildlife and conflict-free land available and there is no more need for forest areas to be changed." What can we infer from the passage?

[
"The plantation of oil palms has decreased in recent years.",
"The Dura produces less oil than other two types of palm fruit.",

It turns out that nodding off in class may not be such a bad idea after all, as a new study has shown that going to sleep shortly after learning new material is the best way to remember it. According to US lead author Jessica Payne, a psychologist at the University of Notre Dame in Indiana, nodding off after learning something new is like "telling" the sleeping brain what to remember. Along with colleagues, she studied 207 students who habitually slept for at least six hours per night.Participants were casually selected to study declarative , semantically related or unrelated word pairs at 9am or 9pm, and returned for testing 30 minutes, 12 hours or 24 ours later. Declarative memory refers to the ability to remember facts and events with awareness, and can be broken down into episodic memory (memory for events) and semantic memory (memory for facts about the world).People routinely use both types of memory every day--recalling where we parked today or learning how a colleague prefers to be addressed. At the 12-hour retest, memory overall was better following a night of sleep compared to a day of wakefulness. At the 24-hour retest, with all subjects having received both a full night of sleep and a full day of wakefulness, subjects' memories were better when sleep occurred shortly after learning, rather than following a full day of wakefulness. "Our study confirms that sleeping directly after learning something new is beneficial for memory.What's new about this study is that we tried to shine light on sleep's influence on both types of declarative memory by studying semantically unrelated and related word pairs," Payne said. "Since we found that sleeping soon after learning benefited both types of memory, this means that it would be a good thing to practise any information you need to remember just before going to bed.In some sense, you may be 'telling' the sleeping brain what to remember." The 24-hour retest shows that subjects' memories were better following _ .

When one person gains weight, their close friends often follow. Researchers have just offered evidence in a study that says obesity appears to spread through society. But the findings might also offer hope. If friends help make obesity acceptable, then they might also be influential in losing the fat. The researchers note that support groups are already an effective tool in dealing with other socially influenced problems, like alcoholism . The findings appeared in the New England Journal of Medicine. The researchers used information collected from 12,000 people. It was collected between 1972 and 2003 as part of the Framingham Heart Study. The information was highly detailed. There was even contact information for close friends of the people in the study. The researchers examined more than 40,000 social ties. They found a person's chances of becoming severely overweight increased by 50% if a friend had become obese. A sister or brother of a person who became obese had a 40% increased chance of becoming obese. The risk for a wife or husband was a little less than that. Nicholas Christakis of Harvard Medical School was a lead researcher in the study. He says there is a direct causal relationship between a person getting fat and being followed in weight gain by a friend. The study found that the sex of the friends was also an influence. In same-sex friendship, a person had a 71% increased risk of becoming obese. Men had a 44% increased risk of becoming obese after weight gain in a brother. In sisters, it was 67%. The researchers also considered the effect of where people lived in relation to each other. James Fowler of the University of California was the other lead expert. He says a friend who lives a few hundred kilometers away has as much influence as one in the same neighborhood. He says the study demonstrates the need to consider that a major part of people's health is tied to their social connections. Both researchers say their research shows that obesity is not just a private medical issue, but also a public health problem. James Fowler seems to believe that _ .

In today's world, we rely on computers as never before.They are used for everything from ordering a pizza to running hospitals and military defense systems.Banking and credit card information is stored and accessed by computers.So what happens when a computer gets infected with a virus? One effect is that people's access to their e-mail accounts is cut off.A more serious possible consequence is that billions of dollars could be lost. A virus is a computer program that copies itself onto other programs and infects them. Similar to an easily spread disease, a computer virus goes from computer to computer, either adding to or changing the tasks a program is designed to do. The first computer viruses were created in the mid '80s and had varying effects.Some caused files to be deleted, or made the letters on the screen appear to fall off.Others displayed a specific message once the computer was turned on. Viruses today are much more widespread and dangerous than ever before.Perhaps the most damaging to date has been the "I Love You" virus."I Love You" appeared in May 2000 and has possibly been the most destructive virus in terms of monetary loss. The virus is released when an attachment to a fake e-mail message is opened.By changing the names of files on computers, "I Love You" makes them difficult to access.It also searches for important personal information, including passwords, which it sends to a web site for others to see. It is estimated that more than 45 million people in 20 countries have had their computers infected by the "I Love You" virus.Some say the cost of repair and lost business has been more than US$10 billion. If you own a computer, it is important to keep it in good health by installing an anti-virus program.If updated frequently, it will protect your e-mail access-not to mention your wallet. How does "I Love You" virus spread?

It seems that all your friends' names on MSN have added a little green "I'm" symbol overnight. If you ask what is going on, someone will tell you it's a charity activity. Though this charity program has not yet officially begun for Chinese users, this little green symbol has proven popular among Chinese Windows Live Messenger users. Windows Live Messenger's official blog announced on March 1 that Microsoft was beginning an "I'm" program in the United States. Every time someone starts a conversation using "I'm", Microsoft shares a part of the program's advertising income with nine organizations devoted to social causes. With every instant message a user sends, it helps deal with things one feels most interested in, including poverty, child protection, disease and worsening environment. One only has to add a certain code next to one's name for the organization one would like to support. "*red'u" is for the American Red Cross, "*bgca" is for Boys & Girls Clubs of America and "*unicef" stands for the American branch of UNICEF. After a Chinese blogger named "hung" introduced this program on his blog on March 2, "I'm" entered the Internet in China with no actual support from Microsoft. Beijing-based Youth Weekend reported that famous IT blogger Keso regarded this program's rapid spread as a successful virus marketing case. He thinks that the success of the "I'm" program is because it's spread by users without being a bother to others. This answers why "I'm" has spread so rapidly across the Internet like a virus with almost no advertisement. However, Feng Jinhu from the press center for Microsoft China toldYouth Weekendthat the "I'm" project is only for Messenger users in the United States. Instant messages sent by Chinese users would not count. This has not affected Chinese Messenger users' interest in the little green symbol. These users hope their instant messages will actually contribute to charitable organizations someday. The following descriptions about the "I'm" program are correct EXCEPT _ .

"it became popular in China in a short time",

Facebook is now used by 30 million people in the UK, around half the population. Joanna Shields, vice president of Facebook Europe, made the announcement this morning at a media conference in London. Globally, Facebook has more than 500 million registered users, a milestone it hit last summer. Last July it had 26 million registered UK users. In the last eight months, it has attracted four million extra UK users, bringing the UK total to 30 million. Facebook, the brainchild of Mark Zuckerberg while he was still studying at Harvard University, was launched in February 2004. The pace of its global growth has sped rapidly - Facebook had only 150 million registered users in January 2009. One third of women aged between 18 to 34 check Facebook when they first wake up, before even going to the toilet, according to the research. 21% check Facebook in the middle of the night, while 42% of the same group think it is fine to post drunken photos of themselves onto the social network, a study by Oxygen Media and Lightspeed Research found. Shields was speaking this morning at the Financial Times Digital Media and Broadcasting Conference about the power Facebook's referrals can bring to media sites, such as newspapers and TV services. She explained that the average Facebook user has 130 friends who they share links to media sites with regularly. "Media companies which take advantage of that are really seeing the benefits," Shields said. Shields refused to be drawn on whether Facebook would develop its own mobile phone operating system and also said it was "silly" that Google had recently _ the feature which allowed Google users to refresh their contacts with Facebook friends. Eight months ago the number of registered users of Facebook in UK was about _ .

What's delicious to eat and comes in a variety of color1s? Eggplant! And no, it has nothing to do with chickens! This strangely named vegetable is, however, as versatile as an egg.It can be steamed, fried, and baked.It can be eaten by itself or combined with meats and other vegetables. Eggplant was first grown in India in the 5th century BC. Its popularity soon spread to China and then throughout Asia.Finally, during the Middle Ages the vegetable made its way to Europe. At that time, eggplant was not the shiny purple vegetable most people know today.Instead, it resembled a white egg. Due to this egg-like appearance, eggplant got its name.In its early days, the vegetable was so bitter that people often called it a "mad apple." This nickname started because people believed its bitterness was bad for one' s health. People actually thought eggplant could cause insanity and cancer. Fortunately today people know that eggplant doesn't cause insanity or cancer.In fact eggplant is so healthy that it may prevent cancer.In addition, the brain and the heart benefit from this super vegetable.Since it's high in fiber, eggplant can improve digestion. Italy, Turkey, Egypt, China and Japan are the leading growers of eggplant in the world today.Depending on its location, eggplant may be purple, green, orange or yellow-white.And it can be as small as a tomato or as large as a cucumber.Dish varieties range from simple to complex, with all of them being delicious. Today, thousands of people gather in Loomis, Calif, for the annual Loomis Eggplant Festival.The main activity at the festival is eating delicious eggplant dishes.There is plenty more to do and see, though.Recipe contests, arts and crafts, performers, races and children's activities all "egg-cite" festival-goers.Most people at the festival would agree--eggplant is an "egg-cellent" vegetable. Which of the following does NOT belong to the qualities of eggplant?

There are new findings that not enough sleep may cause people to gain weight. Researchers say a lack of sleep can produce hormonal changes that increase feelings of hunger. In one study, researchers in the United States examined information on more than 1000 people. The people had taken part in a long-term study of sleep disorders. Some people slept less than five hours a night. They had 15 percent higher blood levels of a hormone called ghrelin than people who slept eight hours. And they had 15 percent less of the hormone leptin. Experts say ghrelin helps make people feel hungry; leptin makes you feel full. The scientists say these hormonal changes may be a cause of obesity in Western societies. They note the combination that sleep limitation is common and food is widely available. The results were not affected by how much people exercised. People who are awake longer have more time to burn energy. But the researchers say loss of sleep may increase hunger especially for high-calorie foods, so people gain weight. It seems that, for survival, the body may be designed to store more fat during times with less sleep. Researchers from Stanford University in California and the University of Wisconsin did the study. They found that the best amount of sleep for weight control is 7.7 hours a night.The Public Library of Science published the findings in its journal Medicine . Internet users can read the full study, free of charge, at plos. org. When you sleep 7.7 hours a night, you will _ .

They crossed in front of me as I was driving out of the store parking lot .I would be delayed for a whole ten seconds. However,I realized that it was an elderly couple who were briefly delaying my departure .No more anger. The man leaned on his wife who walked in front of him. He not only used her for support but it was obvious that he was blind. She was his eyes as well. The two of them worked as one--each needing the other to function in this fastchanging world. That little example of true strength that day changed my whole personal perception of life. Suddenly I wasn't so mad about having to work a few extra hours on Saturday. I had my strength,and I was still relatively young. That picture of those two elderly people walking with dignity and strength stayed with me the entire week. My life wasn't so bad after all. I had my health and a good job. My wife always gave me good advice whenever I needed it. I started to think--not only was I lucky to have it all,but so was that wonderful old couple,who,despite the trials and hardships of a long life,still had the love and support of each other to carry them through this world. There are so many people out there just like that couple. My wife and I sometimes picture ourselves in our old age,walking arminarm into the sunset. That image always gives us a warm feeling of comfort. Just remember,none of us would be here if it weren't for our elders. We should spend an extra minute to listen and learn when it comes to helping our elder friends. They need it. Before meeting the old couple,the author had a(n) _ attitude towards life.

Late last summer, I was introduced to a new special someone. We met at an Apple product announcement. She was helpful, smart, and even funny, talking of jokes and making me laugh. What more could a man ask for? Since then, we have had some major communication issues. She frequently misunderstands what I'm saying. Sometimes she is just unavailable. Often, she responds with the same repetitive statement. Her name is Siri. At first, Siri, the voice-activated digital assistant on Apple Iphones, seemed a little too good to be true. Siri cheated me into a relationship promising to help me set up appointments, to gently wake me in the morning for work, and to give me the ability to text someone while I was driving. It didn't work out that way. "There's something wrong, and I can't answer your questions right now. Please try again in a little while," Siri will say when I ask something, or: "I'm really sorry about this, but I can't take any requests right now. Please try again in a little while." She is always polite. But I'm starting to suspect that "I'm really sorry" is just something Siri says to shut me up. Apple introduced Siri as a beta test, meaning it was still a work in progress. That was unusual for Apple. It wanted a head start. But it doesn't seem ready to change anything yet. Many people I have spoken to have switched Siri off and turned to the iPhone's voice dictation service, which is more reliable because it doesn't use Siri's artificial intelligence software. Over time, things have really gone bad between Siri and me. We hardly speak anymore. Although she doesn't know this, I've started seeing someone else. Her name is Google Voice Search (GVS). GVS, available in the latest operating software, is a much better listener. It's ly smarter. If I ask GVS a question, like, "Who is Tim Cook?", it responds with an answer " He's the chief executive of Apple". If I ask Siri the same question, the response is: "I don't see Tim Cook in your contacts." Why do more people choose not to use Siri any longer?

Do you know why different animals or pests have their special color1s? Their color1s in them seem to be used mainly to protect themselves. Some birds like eating locusts , but birds cannot easily catch them. Why? It is because locusts change their color1s together with the change of the color1s of crops . When crops are green, locusts look green. But as the harvest time comes, locusts change to the same brown color1 as crops have. Some other pests with different color1s from plants are easily found and eaten by others. So they have to hide themselves for lives and appear only at night. If you study the animal life, you'll find the main use of color1ing is to protect the animals themselves. Bears, lions and other animals move quietly through forests. They cannot be easily seen by hunters . This is because they have the color1s much like the trees'. Have you ever noticed an even stranger act? A kind of fish in the sea can send out a kind of very black liquid when it faces danger. While the liquid spreads over , its enemies cannot find it. And it immediately swims away. So it has lived up to now though it is not strong at all. From the passage we can learn that locusts _ .

The uninvolved dad, turning up his nose at diapering and too busy to bathe, dress and play with his kids, is mostly a myth , a big government survey suggests. Most American fathers say they are heavily involved in hands-on parenting, the researchers found. The results are encouraging and important " because others have found the more involved dads are, the better the outcomes for their children. " said researcher Jo Jones of the National Center for Health Statistics, part of the Centers for Disease Control Prevention. She co-authored the report released Friday. "Times have changed," said Robert Loftus, 34, of Yonkers, NY. He quit a six-figure sales job a year ago to care for his two young children while his wife works full time. "We are trying to rethink our priorities and family seem to be N0 1 priority while in the past maybe people were more focused on career. " The study involved nearly 4.000 fathers who were interviewed in person between 2009 and 2013. *Key findings among fathers living with children younger than 5 : *9 in 10 bathed, diapered, helped them use the toilet or get dressed at least several times weekly . * Even higher numbers played with them and ate meals with them that often * Almost 2 0ut of 3 read to them at least several times weekly. *Among dads living with kids aged 5-18. * More than 9 0ut of 10 ate meals with them at least several times weekly and talked with them about what happened during the kids' day that often. * Almost 2 0ut of 3 helped with homework several times weekly. * About half took their kids to or from activities that often. Dr. David Hill, a Wilmington, N. C. pediatrician said the survey reflects what he's seen among his patients' fathers. Increasingly, fathers rather than mothers take their kids to the doctor. Some "are anxious about changing a diaper, " he said. Census numbers show that there were almost 190,000 stay-at-home dads nationwide last year versus 93,000 in 2010. Loftus, the New York stay-at-home dad, said, "I feel fortunate to be able to be such a hands-on father. I'm doing the most significant occupation in the world.

Federal regulators Wednesday approved a plan to create a nationwide emergence alert system using text messages delivered to cell phones. Text messages have exploded in popularity in recent years, particularly among young people. The wireless industry's trade association, CTIA, estimates more than 48 billion text messages are sent each month. The plan comes from the Warning Alert and Response Network Act, a 2006 federal law that requires improvements to the nation's emergency alert system. The act tasked the Federal Communications Commission (FCC) with coming up with new ways to alert the public about emergencies. "The ability to deliver accurate and timely warnings and alerts through cell phones and other mobile services is an important next step in our efforts to help ensure that the American public has the information they need to take action to protect themselves and their families before, and during, disasters and other emergencies," FCC Chairman Kevin Martin said following approval of the plan. Participation in the alert system by carriers--telecommunications companies is voluntary, but it has received solid support from the wireless industry. The program would be optional for cell phone users. They also may not be charged for receiving alerts. There would be three different types of messages, according to the rules. The first would be a national alert from the president, likely involving a terrorist attack or natural disaster. The second would involve "approaching threats," which could include natural disasters like hurricanes or storms or even university shootings. The third would be reserved for child abduction emergencies, or so-called Amber Alerts. The service could be in place by 2014. The improvement to the present system is in the charge of _ .

Governors, lawyers and business leaders have to deal with scientists, and every educated person finds his views affected by science. Yet our science teaching of non-scientists, in school and college, has built up mistaken ideas, dislikes, and the common boast, "I never did understand science.' Even those students who arrive at college with plans to become scientists usually bring a mistaken picture of science: some have a collection of unorganized facts about science, and some regard the study of science as a game which includes getting the right answer. The first of these attitudes seems to come from a kind of course which provides various kinds of information; the second, from a training course on how to pass examinations that do not ask about the student's understanding but simply require him to put the numbers in the right formulas . Neither type of courses (in school or college) seems to give students and understanding of science as we find it among scientists. Neither shows students how real scientists work and think how the facts are gathered, how discoveries are made, and what they mean. Young people need good teaching of science, not so much a great wealth of knowledge as a healthy understanding of the nature of science. They need an understanding of knowledge leading to sympathy with science and an eagerness of the way scientists work. Given these, it is easy to encourage later reading and learning. A good course of science is _ .

Growing in Philadelphia, Lieberman started cooking with his stay-at-home dad when he was seven. His food-loving family had two kitchens, and quickly learned what was the best way to bake his cakes. Lieberman improved his kitchen skills greatly during a year abroad before college, learning from a cook in Italy and studying local specialties in Germany, Spain and France. At Yale, he was known for throwing dinner parties, single-handedly frying and baking while mixing drinks for dozens of friends. Just for fun, he and some friends decided to tape a show named Campus Cuisineabout his cooking. Lieberman was a real college student showing his classmates how to do things like make drinks out of dining-hall fruit. That helped the show become very popular among the students. They would stop Lieberman after classes to ask for his advice on cooking. Tapes of the show were passed around, with which his name went beyond the school and finally to the Food Network. Food Network producer Flay hopes the young cook will find a place on the network television. He says Lieberman's _ is key."Food TV isn't about food anymore,"says Flay."It's about your personality and finding a way to keep people's eyeballs on your show." But Lieberman isn't putting all his eggs in one basket. After taping the first season of the new show, Lieberman was back in his own small kitchen preparing sandwiches. An airline company was looking for someone to come up with a tasteful, inexpensive and easy-to-make menu to serve on its flights. Lieberman got the job. Why did the airline company give Lieberman the job?

Parents whose children think the latest Nike or Adidas shoes may be better than buying old-fashioned plimsolls because they encourage a healthier style of running, researchers said. Big companies, like Nike and Adidas, make millions of dollars from selling highly-cushioned shoes both as fashion and sports shoes. The researchers warn that wearing such shoes from an early age can make it difficult to run in a healthy way. Once we have grown used to running in this kind of shoes, it is very difficult to change our technique, even if we remove our shoes, it can raise the risk of injury. Children should be encouraged to wear shoes with thin soles such as plimsolls from a young age to help them develop a natural "barefoot" running style, experts said. Dr Mick Wilknson, who did the research, told the British Science Festival in Newcastle, "If I would advise someone on what to give their child, I would say don't go and buy them expensive Adidas or Nike, just get them a pair of flexible, flat shoes. Give them basic foot-ware, nothing fancy, nothing particularly cushioned." Running in flat shoes, barefoot, encourages the runner to use the front of their foot which is a better technique for running, especially long distances as the human was designed to do. Around the world, and in particular in the US, running barefoot is becoming more and more popular with many long distance runners training without shoes. Dr Mick Wilknson believes that training and running barefoot or in flat running shoes can help reduce injuries to runners, he said: "Injury rates in running have not changed since the 1970s, despite claims of improvements in running shoes. That has led some to conclude that barefoot running is better." Who is the passage written mainly for?

The World Health Organization says there has been a sharp increase in the number of over-weight children in developing countries. In African countries, the WHO says the number of over-weight or obese children is twice as high as it was 20 years ago. Around the world, about 43 million children under the age of five were overweight in 2013. Overweight and obese children are more likely to become overweight and obese adults. The condition can _ serious health problems like heart diseases. Francesco Branca is the director of the WHO Department of Nutrition for Health and Development. He says urban lifestyle makes people eat processed food more often ,which has a high sugar ,fat and salt content. He also says people are gaining weight because of their lack of activities. They travel in cars or other vehicles more than on foot. The WHO experts say to lower obesity rates is especially complex in countries that also deal with high rates of infectious diseases. The WHO has some basic solutions for individuals and countries. The organization says you should lower your intake of fat, sugar, salt and processed food and eat more fruits,' vegetables and increase physical activity. The WHO says these actions are especially important for children. And WHO expert Branca says mothers should breastfeed their babies for at least the first six months of life, if possible. More importantly, governments should consider providing vitamins for children and educational campaigns about problems linked to obesity would also help. In his view, government policies should deal with how food is marketed to children and food producers must balance quality and taste with the dangers of sugar, fat and salt. "Reducing the number of overweight children will not be easy. The goal is difficult to meet even in wealthy countries. " he adds. According to WHO, which of the following is true?

"Poor nutrition is often related to children obesity.",
"To lower infectious disease rates is more complex than to lower obesity rates.",

My students often tell me that they don't have "enough time" to do all their schoolwork. My reply is often a brief "You have as much time as the president."I usually carry on a bit about there being twenty-four hours in the day for everyone, and suggest that "not enough time" is not an acceptable explanation of not getting something done. Once in graduate school,I tried to prove to one of my professors by saying that I was working hard.His answer to me was. "That's irrelevant .What's important is the quality of your work. " Since then I have had time to think carefully about the "hard worker" dodge ,and I have come to some conclusions--all relevant to the problem of how much time we have. If you analyze the matter, you can identify two parts of the prob1em:There is, of course,the matter of "time", which we call think of as fixed. Then there is the problem of "work" during that time. But, as my professor suggested, it's not how hard one works but the quality of the product that's important. That led me to a new idea: the quality of the work.That concept is perhaps best explained by a sign I once saw on the wall in someone s office: "Don't work harder. Work smarter." There is a lot of sense in that idea. If you can't get more time,and few of US can,the only solution is to improve the quality of the work.That means thinking of ways to get more out of the same time than we might otherwise get.That should lead us to an analysis of our work habits.Since "work" for students usually means "homework", the expression "work habits' should be read as "study habits". Then, as a smart student,you will seek to improve those skills that you use in study, chiefly reading and writing. If you learn to read better and write better,there are big advantages that pay off in all your studies. From the passage,we know that the author is probably _ .

What if you arrived home to find a delicious hot meal waiting for you,prepared by your very own kitchen robot? It might sound like science fiction,but professors at the university of Tokyo have taken the first steps toward making that scenario a reality.The team recently introduced a humanoid kitchen robot that can pour tea and other drinks into cups and serve them to guests.When teatime is over,the robot can also wash the dishes and put them away. In California,another interesting kitchen robot has been developed.Called the Readybot,it can pick up objects and either store them in cabinets or put them in the trash.It also carries a separate floor-cleaning robot that can operate by itself.Unlike the Japanese robot,Readybot is not humanoid.Instead,it looks more like a large box with arms and wheels. Readybot was created by engineers and designers who established a club called the Readybot Challenge.They believe that in the future millions of robots will be needed in homes to perform ordinary household tasks.Readybot is just the first step in their plan to create a robot that can tackle jobs not only in kitchens but in other rooms of homes and in offices as well. Clearly there are technological hurdles to overcome before robots can cook a complete dinner,and there are also many safety concerns.Not everyone(especially parents)would be comfortable with the idea of robots in their house,manipulating hot pans and sharp knives.The European Commission recently funded a project to study these concerns. Where do the engineers and designers hope that Readybot will operate in the future?

In the past two decades, the Chinese economy has undergone many reforms in an effort to compete more effectively on the international market.These reforms included allowing foreign hanks to offer credit cards to Chinese citizens, Now, researchers at the University of Missouri (MU)have found about 30 percent of Chinese urban households now own at least one credit card and the growth rate of credit card adoption has been an average of 40 percent per year between 2004 and 2009. Rui Yao, an assistant professor of personal financial planning at MU, says that this large growth in such a small amount of time has positive and negative implications for the Chinese economy. "With more and more people taking advantage of credit in China, it certainly increases potential consumer buying power," Yao said."However, we found that more than 90 percent of non-credit card users were unaware of safety issues existing in credit card use and more than 60 percent had little knowledge of the consequences of credit card debt.Thus lack of knowledge could create problems as credit card ownership is expected to grow at a rate of I percent a year." Yao found that would 72 percent of Chinese credit card holders were never late on their payments, only 55 percent were able to pay the full balance.She also found that 70 percent of Clones credit card holders said that credit cards contributed to overspending. Yao believes the Chinese could benefit from facial education designed to help them plan for their financial future and encouraging the Chinese to take advantage of debt in a responsible fashion is important for the Chinese economy."Appropriate use of debt can help households improve their quality of life as well as spur economic growth through an increase in market purchases." Yao said. Why did China allow foreign banks to offer credit cards to Chinese citizens?

No matter who you are or where you come from, one thing is certain: you are familiar to the mosquito, although you probably wish you weren't. Mosquitoes are everywhere. They can be found all over the world, and they come in more than 2,500 species . Somewhere, at some time, you have surely met at least one. No one loves the mosquito. But unfortunately, the mosquito may decide who she loves. She? Yes, she. Do you know that only the female mosquito bites? Well, it's true. And it's not because she is unfriendly; she needs blood to reproduce. Do you know how the female mosquito decides whom to bite? She is quite selective, and she chooses her victims carefully. First, she uses sensors to find her victim. These sensors are located on her two antennae and her three pairs of legs. With these sensors, she tests your body moisture, body warmth, and chemical substances in your sweat. If she likes what she finds, she bites. But if you are not attractive, she'll reject you for another one. The next time a mosquito bites you, just remember that you are chosen. You are special. If the mosquito likes you, she settles onto your flesh very gently, and she breaks your skin with her long nose tip. Long nose tip? What's that? It's a kind of mouth and it sticks out just below the mosquito's eyes. It contains six sharp instruments called styles. She thrusts all six styles into your skin at once, and if she hits a blood pipe, she'll get a full dinner in about a minute. All this usually takes place so quickly and quietly that you may not have doubted anything is happening. Why does a mosquito bite itch ? The itch is not really from the bite. lt's from the saliva the mosquito mixes with your blood to keep it from being blocked as she sucks up her long nose tip. By the time the itch begins, she has gone. And then what happens? Well after her delicious dinner, the mosquito is tired. She just wants to find a place to rest. Heavy with your blood, she picks a spot on a leaf, a wall or a stone to quietly lay her eggs. Just one drop of blood will produce hundreds of eggs. It is _ that makes you itch.

A recent study of ancient and modern elephants has come up with the unexpected conclusion that the African elephant is divided into two distinct species. The discovery was made by researchers at York and Harvard Universities when they were examining the genetic relationship between the ancient woolly mammoth and mastodon to modern elephants -- the Asian elephant, African forest elephant, and African savanna elephant. Once they obtained DNA sequences from two fossils , mammoths,and mastodons the team compared them with DNA from modern elephants. They found to their amazement that modern forest and savanna elephants are as distinct from each other as Asian elephants and mammoths. The scientists used detailed genetic analysis to prove that the African savanna elephant and the African forest elephant have been distinct species for several million years. The divergence of the two species took place around the time of the divergence of Asian elephants and woolly mammoths. This result amazed all the scientists. There has long been debate in the scientific community that the two might be separate species, but this is the most convincing scientific evidence so far that they are indeed different species. Previously, many naturalists believed that African savanna elephants and African forest elephants were two populations of the same species, despite the elephants' significant size differences. The savanna elephant has an average shoulder height of 3.5 metres while the forest elephant has an average shoulder height of 2.5 metres. The savanna elephant weighs between six and seven tons, roughly double the weight of the forest elephant. But the fact that they look so different does not necessarily mean they are different species. However the proof lay in the analysis of the DNA. Alfred Roca, assistant professor in the Department of Animal Sciences at the University of Illinois, said, "We now have to treat the forest and savanna elephants as two different units for conservation purposes. Since 1950,all African elephants have been conserved as one species. Now that we know the forest and savanna elephants are two very distinctive animals, the forest elephant should become a bigger priority for conservation purposes." The researchers' conclusion was based on a study of the African elephant's _ .

It is easier to go down a hill than to climb up a hill, so it is to fall into bad habit than into good ones. Bad habits do not come suddenly. They come little by little while people do not notice their danger. Some schoolboys first pick up bad habits in school and on the streets. When they cannot finish their lessons, they copy from their classmates. If they see bigger boys smoking, they also want to learn to smoke. When they are older, the habits become so strong that they can never get rid of them. From copying, they fall behind, then learn to steal, and smoking is bad for their health. At last they become worse and worse. How necessary it is that we get rid of the bad habits at the very beginning. When they grow, bad habits will _ .

A recent study suggests that teens' relationship with parents, friends and teachers may have a lot to do with why they don't get a good night's sleep. David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens' sleep. And problems at school also affected teens' sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night's sleep. These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we're happy and contented, we're much more likely to sleep better than if we're sad and anxious. Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It's a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers. Clearly, teenagers aren't getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress. What is the passage mainly about?

Encourage them to get moving and get off the couch by giving them a pedometer . Pedometers are the most fun when parents also use one because that turns stepping, walking and running into a game to see who can get the most steps. Thursday The kids have done a great job so far this week, but now they long for a little more TV time. Instead of turning on cartoons, let them watch fitness movies made just for kids. These movies encourage watchers to get up and dance along to kid-friendly music. Saturday Get the whole family out of the house together and over to a park. Bring lots of sports equipment, pack a healthy picnic and have a family competitive sports day. Kids and adults get into groups and play against each other in tennis, basketball or soccer. After everyone has played hard for a couple of hours, stop for a picnic and then if your family isn't too tired, go back and play some more.

Conventional wisdom says that hardship can make us old before our time. In fact, a new study suggests that violence not only leaves long-term scars on children's bodies, but also changes their DNA, causing changes that are equal to seven to ten years of premature aging . Scientists measured this by studying the ends of children's chromosomes , called telomeres, says Idan Shalev, lead author of a study published in Molecular Psychiatry. Telomeres are special DNA sequences which prevent the DNA in chromosomes from separating. They get shorter each time a cell divides, until a cell cannot divide any more and dies. Several factors have been found to shorten telomeres, including smoking, radiation and psychological stresses such as being treated badly when young and taking care of a chronically ill person. In this study, researchers examined whether exposure to violence could make children's telomeres shorten faster than normal. They interviewed the mothers of 236 children at ages 5, 7 and 10, asking whether the youngsters had been exposed to domestic violence between the mother and her partner, physical maltreatment by an adult or bullying. Researchers measured the children's telomeres--in cells obtained from the insides of their cheeks--at ages 5 and 10. Telomeres shortened faster in kids exposed to two or more types of violence, says Shalev. Unless that pattern changes, the study suggests, these kids could be expected to develop diseases of aging, such as heart attacks or memory loss, seven to 10 years earlier than their peers. Shalev says there is hope for these kids. His study found that, in rare cases, telomeres can lengthen. Better nutrition, exercise and stress reduction are three things that may be able to lengthen telomeres, he says. The study confirms a smallbutgrowing number of studies suggesting that early childhood hardship imprints itself in our chromosomes, says Charles Nelson, a professor of pediatrics and neuroscience at Harvard Medical School. Which of the following is TRUE, according to the text?
|
[
"Researchers measured the children's telomeres from their legs in the study.",
"Kids interviewed in the study are exposed to two or more types of violence.",
"Children who have shorter telomeres may suffer from a heart attack earlier.",

I was never neat, while my roommate Kate was extremely organized. Each of her projects had its place, but mine always hid somewhere. She even labeled everything. I always looked for everything. Over time, Kate got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both get tired of each other. War broke out one evening. Kate came into the room. Soon, I heard her screaming, " take your shoes away! Why under my bed!" Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder. The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled under her covers, sobbing. Obviously, that was something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart. Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn't notice Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me, "thanks." Kate and I stayed roommates for the rest of the year. We didn't always agree, but we learned the key to living together; giving in, cleaning up and holding on. What made Kate so angry that evening?

The poorer mental function seen among alcoholics, many of whom also regularly smoke cigarettes, may be partly caused by the long-term effects of nicotine , new study suggests. "People who are also smokers are more dangerous," Dr. Jennifer M. Glass, of the University of Michigan's Addiction Research Center, said. In her study, "cigarette smoking had bad effects on IQ and thinking," she said. This finding may seem wrong because many smokers feel better after smoking. Studies show that up to 87 percent of alcoholics smoke cigarettes. Yet, few studies have looked into cigarette smoking as a reason that might explain the cognitive deficits reported among alcoholics. To find out that connection, Glass and her partners examined brain function among 172 men from the same community, including 103 men who are alcoholics. The team found that heavy smokers and those alcoholics both had lower IQ scores. In the further study, the experts found that smoking also appeared to be connected with weaker verbal and visual-spatial reasoning . So, though smoking did not account for all of the poorer mental function among the alcoholics, it did seem to account for some of the effects, the report shows. What's the purpose of the study that was carried out by Glass and her partners?

"To study if cigarette smoking can cause the cognitive deficits among alcoholics.",
"To show that smoking and drinking has much connection with IQ and thinking ability.",
"To show that smoking and drinking has little connection with IQ and thinking ability.",

These days, when the world seems to be hard to control, walking can make you feel peaceful. It gives you a chance to slow down, to relax and to appreciate yourself and your life in general. It helps you slow down enough to breathe deeply, to calm your thoughts, and to research the natural world filled with wonders. And yes, to love yourself more. Try to spend one day for a long travel on foot--far from the requirements of work and family. First, choose a date and mark it as your "relaxing day". Next, choose a place that you want to visit on foot. If you enjoy being out in nature, head to a wide and open place. Try to choose a place that's no more than 15 minutes from your home. You want to spend your time walking, not driving. Walk at an easy speed so you can walk longer and farther. If you normally walk two miles a day, go for four to six miles. Wear comfortable clothes. If it's warm, wear a hat to protect your face. And don't forget your sunglasses-- not only to protect your eyes but also to give you a sense of privacy while you walk. Before you go out, get up early so you can spend a few minutes relaxing. Relaxing is something few people spend in their spare time, but it leaves you feeling much lighter and less annoyed. Read something relaxing before you leave home, and it'll put you in a different condition of mind. And, of course, eat a healthy breakfast and drink plenty of water. Then pick up your backpack and head out. And enjoy yourself. Before you go out for a walk, you should _ .

I was a medical student. To gather data for my paper, I started visiting patients at Dr Sardjito Hospital, where I would review the medical records of patients and then interview them. One evening, I was in a ward , desperately "hunting" for the final three patients I needed to complete my study. Holding a patient questionnaire, I walked towards a room. A patient called Ms A was lying in bed, clearly still weak. There were no relatives or friends with her. Even the bed beside her was empty. I sat down on a chair next to her bed, and in a low voice I introduced myself and asked if I could gather some additional information from her. She agreed. After I finished, I prepared to leave. Before I could stand up, Ms A said, "I haven't seen you here before, doctor. Are you new?" "Not really, Madam. It's just that I don't come here every day," I replied. Ms A started talking about herself. She shared her difficulties and sufferings, talked about her husband, who was killed in a car accident, and that she struggled to earn money. All I did was nod my head as a way of showing my sympathy. Without realizing it, I had begun holding Ms A's hand. Finally, Ms A stopped talking. "I'm very sorry for keeping you here to listen to my problem, but I feel relieved now. I had no one to pour out my problems to." Tears fell from the corner of her eyes. Finally, I knew what to say. "It's OK, Madam. It's part of my duty." I stood up and waved goodbye. A few days later, when I returned to the ward, I discovered Ms A had left the hospital as her condition had improved. Ms A taught me the most important lessons a doctor can learn. Sometimes patients do not need expensive medicine. They just need someone with the patience and willingness to lend an ear and spare a little of their time. Ms A tended to think that _ .

In the next five years, STEM (science, technology, engineering and mathematics) jobs are projected to grow twice as quickly as jobs in all other fields according to the U.S. Bureau of Statistics. While all jobs are expected to grow by 10.4 percent, STEM jobs are expected to increase by 21.4 percent. By this measure, future STEM jobs represent a huge opportunity to today's students. But, in fact, of the 3.8 million ninth graders in the U.S., only 233,000 end up choosing a STEM degree in college, according to the National Center for Education Statistics. This means only 6 percent of ninth graders will become STEM graduates. And of these graduates, women will be even more underrepresented in most STEM fields. These are alarming statistics. How do we get more young boys and girls to be interested in STEM-related fields? It isn't an easy task. Schools do not always adequately prepare students for these severe subjects, and college programs are designed to get rid of those who are less persistent. Nationally, only 41 percent of initial STEM majors who begin a degree in STEM-related fields complete their degree in less than six years. In addition, social pressures continue to cast a shadow over girls who might otherwise consider the STEM fields. A couple of years ago, I met amazing parents, both of whom had a background in engineering and hoped their 10-year-old daughter would follow in their footsteps. They encouraged her to take an after-school science / robotics program. When she got there, she found she was outnumbered 6:1 by boys in the class. As the only girl, she came home crying much of the time because she was teased and told that geeky girls are not welcome in the boys' club. Ironically, by the time young boys are entering college programs in STEM fields, many complain about the lack of girls. Starting at an early age, even as young as kindergarten, we need to encourage and help the next generation leaders to consider taking up science, computing, math and technology. We also need to realize that for young girls to be inspired to take and stick with this educational path and later career field, they will benefit from the support of the people that surround them: parents, teachers, friends and family members. From the passage we can learn that few girls enter the STEM fields partly because _ .

If you're obese now, you probably will grow into an obese adult. But here's good news. You can fight overweight. Change your eating habits. You are what you eat, Kids like snacks. Did you list any healthy snacks? One study of eating habits showed that soft drinks are the first in the snack list. Next, kids choose salty snacks, like chips .What's more, the list is full of junk food from No.3 to No.11. Finally, No.12, kids picked a healthy snack--fruit, So, think about your snack choice again. Get outside to exercise Jim, a player on his school football team, had a weight problem not long time ago. He could never get anyone to play with him. So his father and he started playing football for a few minutes every night. Ten minutes turned into an hour or more. In just a few years, the heavy kid became athletic, fit and healthy. More TV means more fat Nearly every American kid watches TV for 2 hours and 56 minutes every day that adds up to 44 days a year of sitting. More TV (or more Internet surfing, or more computer games) means more fat. Eat an apple a day, walk around the house, play with your family...Do it today, and do it more tomorrow. It will help you a lot. According to the passage, kids put _ at the end of the snack list in one study of eating habits.
