There are many commonly held beliefs about eyeglasses and eyesight that are not proved facts. For example, some people believe that wearing glasses too soon weaken the eyes. But there is nothing to show that the structure of eyes is changed by wearing galsses at a young age. Wearing the wrong galsses, however, can prove harmful. Studies show that only children can develop loss of sihgt if they have the wrong glasses. We have all heard some of the common myths about how eyesight get bad. Too little light makes the eyes work harder, so they do get tired and strained . Eyestrain also resulsts from reading a lot, reading in bed, and watching too much television. But, although eyestrain may cause some pain or headaches, it does not harm eyesight all the time. Another myth about eyes is that they can be replaced from one person to another . It is quite difficult to connect aneyeball to a new brain.And it is impossible to replace a whole eyeball to a new person. Only certain parts of the eye can be replaced now. But if we keep clearing up the myths and learning more about the eyes, some day it may be possible to replace a full eyeball. One cause of eyestrain mentioned in the passage is _ . .

Happiness is for everyone . You don't need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on . Why? Because those who have big houses may often feel lonely .and those who have cars may want to work on the country roads at their free time . In fact , happiness is always around you if you put your heart into it.When you are in trouble at school,your friends will help you;when you study hard at your lessons,your parents are always taking good care of your life and your health;when you get success,your friends will say"Cingratulations"to you;when you do something wrong,people around you will help you to correct it.And when you do something good to others,you notice them,and you can see that happiness is always around you. Happiness is not the same as money.It is a feeling of your heart.When you are poor,you can also say you are happy,because you have something else that can't be bought with money.When you meet with difficulties,you can say loudly you are very happy,because you have more chances to challenge yourself.So you cannot always say you are poor and you have bad luck.As the saying goes,"Life is like a revolving door.When it closes,it also opens."If you take every chance to get, you can be a happy and lucky person. Happiness is for _

Maybe you're really busy. Maybe you don't have much to say. Or maybe you're just lazy. Not a problem. This free service works by letting you broadcast a group text message to your friends' mobile phones from either your own phone, an instant message or an online form at twitter.com. All your notes are then stored and displayed on your personal profile page on the site, which includes links to your friends' Twitter pages, a thumbnail picture of your choice, and a short bio. All this is what the new service Twitter can bring you. Just remember to keep it short: posts are limited to 40 characters, and the topic is, invariably, "What are you doing?" More often than not, it turns out, Twitter's 100,000 members--twice as many as it had just a month ago, according to Twitter business development director Biz Stone--are simply killing time. Even Presidential hopeful John Edwards is on it, although he seems to be the only one thinking about more than lunch. As I type this, Caroline is mulling over some Girl Scout cookies, Ian _ Hocking is "waiting for Jessica to arrive so we can eat!" and Hlantz is "having a nice cup of Soft Starmint tea." The chatter about Twitter turned into a virtual roar two weeks ago during the South by Southwest Multimedia Festival in Austin, Texas, when the barebones service owned by Blogger founder Evan Williams, 34, was named the best blogging tool and attendees used it to meet up at parties. Nevertheless, Twitter has been the top term on blog search engine Technorati for the past two weeks. Plenty of people would happily have Twitter silenced, rather than tolerate the beeping alert for yet another new text message. But I'm betting that Twitter will get a lot noisier before netizens move on to the next new thing. We cyber-junkies need a new thrill, and what is better than a service like Twitter that combines social networking, blogging and texting? And if you don't like it, well, in the words of one Twit from San Francisco, "I'm so sick to death of Twitter-haters. If you don't like it, why waste your time writing, reading, or talking about it?"

Computer people talk a lot about the need for other people to become "computer-literate." But not all experts agree that this is a good idea. One pioneer, in particular, who disagrees is David Tebbutt, the founder of Computertown UK. Although many people see this as a successful attempt to bring people closer to the computer. David does not see _ that way. He says that Computertown UK was formed for just the opposite reason, to bring computers to people and make them "people-literate." David Tebbutt thinks Computertowns are most successful when tied to a computer club but he insists there is an important difference between the two. The clubs are for people who have some computer knowledge already. This frightens away non-experts, who are happier going to Computertowns where there are computers for them to experiment on, with experts to encourage them and answer any questions they have. They are not told what to do, they find out.The computer experts have to learn not to tell people about computers, but have to be able to answer all questions people ask. People don't have to learn computer terms , but the experts have to explain in plain language. The computers are becoming "people-literate." We can infer from the text that "computer-lilerate" means _ .

When my friend Lesa was diagnosed with cancer, another friend and I went to the hospital to spend some time with her. We bought her a small toy and named him Lemon-Aide. We gave Lemon-Aide to Lesa and told her he was to go with her to all of her treatments to remind her that we were thinking of her and caring about her even though we could not always be with her. When the treatments were completed, she said when someone else needed him she would pass him along. A few months later,much to my surprise, it was me that she passed him to. Lemon-Aide went with me to all of my treatments. One day while waiting for my doctor I decided we could market the idea to fight cancer. Lesa thought it was a great idea so we founded the organization that came to be known as Lemon-Aide' s Friends, Inc. We designed our organization to remind people fighting cancer that there are people who love and care about them all the time. Today we have totally 5013 volunteers. The money raised is donated to cancer patients who do not have insurance. The physicians on our Board of Advisors determine how and where our money is donated. Lemon-Aide is for men, women, and children of all ages and to date has been sent to 34 states and 33 countries to provide smiling support for people fighting cancer. When life gave us lemons we made Lemon-Aide, a soft smiling toy that represents love, support, and encouragement. The author went to the hospital with her friend _ .

I'm Bolivia Williams, a students at Bard College. I was the only person in my family who was Facebook friends with my mom, Rynn, when she died four years ago. At that time, my brother and sister were still young. As soon as we got the news that she died, I thought it would be an easy way to let everyone know what happened. Right after I posted the news, so many people offered their help and shared stories about her. I like to visit my mom's page to tell her things that I'm doing and I like to look at her pictures there. I sing with the Brooklyn Youth Chorus ,and we did a concert for the tenth anniversary of 9/11,which was also my mom's birthday. It was an unforgettable day. I posted, "You will be proud of me--I will sing at the site of the World Trade Center tomorrow. I know you will be looking down, smiling. "When I'm writing to her, it feels like I'm still here. In the beginning, I wasn't sure how to face my mom's death. But I've grown up now. I haven't been on my mom's page for a month, but I would miss _ if it were gone.

Imagine this: you get up in the morning and put on a custom printed T-shirt. Then you eat some 3-D printed food and relax on your printed sofa. Perhaps you take a ride in a printed electric car to the hospital to get a printed tooth fitted. Though some of these things may seem impossible, they're closer to reality than you might think. The world of 3-D printing is coming to a store near you soon. The idea of 3-D printing is to produce complicated shapes in a very personalized way. If you want to make a totally new object, you need to make a virtual design in a CAD(computer aided design)file first. Or you can use a 3-D scanner to make a digital copy of an object. Then, based on the design or copy, the 3-D printer makes paper-thin slices out of liquid, plastic, or metal and puts them together to create the object you want. There are many areas in which 3-D printing can change our lives. One such area is health care. Researchers have developed simple 3-D printed organs, which can be used in life-saving operations. A 17-year-old boy in the US has also recently developed a brain-powered, 3-D printed replacement hand. From heart monitors to fake limbs , we can soon be living longer thanks to 3-D printed technology. Another area that 3-D technology looks sure to change is food. Can you imagine being able to print your favorite dishes at home at the touch of a button? Even big companies are behind the trend. Hersheys, one of the largest chocolate makers in the world, recently announced that it would start producing chocolate with the help of 3-D printers. NASA, the US space agency, has reportedly spent $125,000 (767,594 yuan) developing a "3-D pizza printer". It is not yet clear how long it will take until 3-D printers are available to everyone. But one thing is for sure: the possibilities are endless. We can infer from the article that _ .

Many children first learn the value of money by receiving an allowance, The purpose is to let children learn from experience at an age when financial mistakes are not very costly ,The amount of money that parents give to their children to spend as they wish differs ,from family to family. At first, young children may spend all of their allowance in no time ,Lf they do this, they will learn the hard way that spending must be done within a budget ,which demands choices between spending and saving ,Older children may be responsible enough to save money for larger costs ,like clothing or electronics. But it is not a good idea to pay your child for work around the home ,These jobs are a normal part of family life , Paying children to do extra work around the house , however, can be useful .It can even provide an understanding of how a business works. Allowances give children a chance to experience the things they can do with money. They can share it in the form of gifts or giving to a good cause .They can spend it by buying things they want., Or they can save and maybe even invest it , Saving helps children understand that costly goals require sacrifice; you have to cut costs and plan for the future. Many banks offer services to help children and teenagers ,lean about personal finance .A savings account is an excellent way to lean about the power of compound interest. Compounding works by paying interest on interest .So, for example, one dollar invested at two percent interest for two years will earn two cents in the first year .The second year, the money will earn to percent of one dollar and two cents,, and so on ,That may not seem like a lot .But over time is adds ,up.

SAN FRANCISCO -- Sales for Apple's third generation iPad has hit record in the first days after it was on the market, Apple and carrier AT&T said on Monday. The new iPad went on sale on March 16 in the United States along with nine additional countries and areas. "We had a record weekend, and we are thrilled with it," Apple's CEO Tim Cook said Monday at a conference. Shortly after the conference call, AT&T said the launch of the new iPad set a new single-day record for its sales. "On Friday, March 16 AT&T set a new single-day record for its iPad sales, showing strong demand for the new iPad on the nation's largest 4G network," said the mobile carrier in a brief announcement. The new iPad is Apple's first 4G-capable product, featuring retina display, HD camera and faster processor. Before hitting stores, the new iPad pre-sales were sold out worldwide in two days. BEIJING -- A Chinese farmer was sentenced to 13 years in prison Monday for stealing art pieces from the Forbidden City last year, court authorities said. Shi Baikui, 27, was fined 13,000 yuan ($2,059) and was deprived of his political rights for 3 years, according to the ruling announced by the Second Intermediate People's Court in Beijing Monday morning. Shi, from East China's Shandong Province, broke into the heavily guarded former home of Chinese emperors in the heart of Beijing, and stole nine art pieces made of gold and jewels, on May 8, 2011, the court said in a statement. While hurriedly escaping, Shi left behind five of the pieces in the Forbidden City's compound . Failing to immediately sell the treasures, he threw the other four pieces away the next day, the document said. Six pieces were recovered and the three missing were worth about 150,000 yuan ($23,760) in total. Shi was arrested by police at an Internet cafe in Beijing's Fengtai district 58 hours after the theft. Which of the following is true?

After spending years searching for a planet with life, scientists may have found one. In September 2010, a team of US scientists discovered a planet called Gliese 581g. It has a surface temperature neither too hot nor too cold for liquid water. Scientists think there is a chance that the planet could have life. The planet Gliese 581g goes around a star called Gliese 581, which is about 20 light-years from Earth. That is about 194 trillion kilometres -500 million times farther away from us than the moon. A spacecraft traveling at a one-tenth of the speed of light would reach Gliese 581g within about 220 years. A human can't live that long, but robotic explorers could make the job easier. However, our fastest spacec raft don't come anywhere near that one-tenth light-speed mark. At present, scientists don't know what the surface might be like on Gliese 581g. What they know is that the planet is at the right distance from its star to have liquid water. It's also at the right distance to have an atmosphere that could protect the water if it is on the surface. Although spacecraft won't be getting there anytime soon, one way to look for life on Gliese 581g is to turn our radio telescopes towards the planet and search for radiation . By studying the radiation, scientists would find out about the chemicals around the planet and discover if Gliese 581g has an atmosphere. If it has one, studying the atmosphere would give us a good idea whether the planet has life or not. But it'll probably be many years before we can do this properly. People have been arguing about whether there is alien life on Gliese 581g. Any discussion about alien life is just guessing at this point, according to its discoverers. What did scientists find in September 2010?

Have you seen a yellow-and-black salamander ? How about a scarlet frog? Scientists haven't spotted either species in more than 20 years. What happened to them? Are the creatures still out there, or are they extinct? Those are questions that scientists hope to answer. They recently set out around the world in search of those and other long-missing amphibians. An amphibian is an animal that spends part of its life in water and part on land. Frog, toads , and salamanders are amphibians. The experts are looking for about 100 species. They are searching at least 14 countries on five continents. They will look for the salamander in North America. They hope to find the scarlet frog in South America. They're also looking for species in Africa, Asia and Australia. Scientists are hopeful that they'll find the amphibians--and soon! If the creatures are out there, they may need help. Many amphibians are endangered. The animals face many dangers including pollution and diseases. People cut down the forests where they live. "If researchers can find the missing creatures, they might be able to figure out how to save them," explains expert Robin Moore. He began searching for the amphibians earlier this month. "This search will tell us a lot about how amphibians are doing," Moore told WR News. "I don't know what we will find, but that makes the search even more exciting." Lost in the Wild Scientists' hunt for missing amphibians is under way. Read about some of the species they hope to find. Turkestanian salamander This salamander is a mystery to scientists. Experts found a few of them more than 100 years ago, but none have been seen ever since. Gastric brooding frog Experts first discovered this frog in 1914 in eastern Australia. It may be extinct because of disease and habitat loss. Rio Pescado stubfoot toad Last sighting: 1995, in South America Scientists hope to find this spotted toad in rivers and rainforests in Ecuador. The animal faces threats including pollution and disease. What does Moore think of the search for endangered amphibians?

I think that the most basic and powerful way to connect to another person is to listen. Just listen. Perhaps the most important thing we ever give each other is our attention and especially if its given from the heart. When people are talking, there's no need to do anything but receive them. Just take them in. Listen to what they're saying. Care about it. Most times caring about it is even more important than understanding it. When we interrupt what someone is saying to let them know that we understand, we move the focus of attention to ourselves. When we listen, they know we care. I have even learned to respond to someone crying by just listening. In the old days I used to reach for the tissues , until I realized that passing a person a tissue may be just another way to shut them down, to take them out of their experience of sadness and pain. Now I just listen. When they have cried all they need to cry, they find me there with them. This simple thing has not been that easy to learn. It certainly went against everything I had been taught since I was very young at school. I thought people listened only because they were too timid to speak or did not know the answer. A loving silence often has far more power to connect and to heal than the most well-intentioned words. It is very difficult for us to learn to listen because _

Many scientists are now exploring the idea of going to live on Mars. Some other scientists from the MASA AMES Center have already started the creation of a "Mars town" and many others are in fact already experimenting with it. Of course, these experiments are done on Earth itself but this "Mars town" has an environment practically like that of Mars. The astronauts working in these towns wear their space suit and also do everything they would really have to carry out if they ever go to Mars in the future. But Mars would be like Earth, a temporary place for humans. When the Sun starts swallowing up the planets, Mars will disappear only hours after Earth. So Mars only seems to be the ideal place to spread the human beings. It is also a good location to send humans if ever there is a disaster on Earth. By saying disaster, I mean asteroids hitting and things like that. If we humans do not want to disappear when Earth or Mars gets swallowed up, we will have to go and live beyond the solar system. But are there any planets outside our solar system prepared to support life? Astronomers' answer is: "If Earth can support life, why can't other planets do the same too? Astronomers have already discovered a Jupiter - like planet _ a Sun-like star, so why not an Earth-like planet orbiting a Sun-like star? To achieve this goal though, many other problems have to be taken into consideration. How do we transform a dusty planet like Mars into one more or less like our Earth? How should we go on? There is still a long way to go. The "Mars town" mentioned in the passage is _

Having just quit a highly moneymaking job with tech giant Microsoft in the United States,where he'd made millions working as a program manager, _ What Awuah wanted was to create a university in his native Ghana.a state-of-the-art education centre that would help educate the country's next generation of leaders.Awuah moved with his family,back to Ghana.There,he invested his own money and with the help of other donors he founded Ashesi University. "Africa needs to have a renaissance ," says Awuah as he explained what drove him to take the risky decision."The world needs to change in this way and I strongly believe that people like me need to be part of the solution;I need to be really actively involved in helping to drive this change in Africa'' Located about an hour's drive from the capital Accra,Ashesi,which appropriately translates to "beginning," is the first Ghanaian university to combine technical majors with a liberal arts approach.Its campus,set on 100 acres in a town called Berekuso,was designed to be inspiring for the more than 500 young Ghanaians studying there. "So when I look at universities I see Africa fast--forward 30 years.When this 20-year-old is now in his or her 50s,that person is going to be a leader." Today Ashesi,which celebrates its 10th anniversary this year,offers degrees in business, information systems and computer science.There are plans to offer engineering and economics majors in the near future.The school's graduation rate is between 70%and 90%,according to Awuah. In our last freshman class,50% of the students paid full tuition ,25%were on full scholarships and 25%on partial scholarships ,"he said."The reason why variety is so important is that the most important conversation on campus is a conversation about the good society--what is the good society we would like to see in Africa? That conversation is a lot more interesting if you have variety in the classroom,"adds Awuah. . Which of the following is TRUE according to the text?

"Ashesi has offered five degrees since it was founded.",

British researchers found that men are almost as likely as women to want children, and they feel more lonely, depressed, angry and sad than women if they don't have them. Childless women were more likely to mention personal wish and biological urge as major influences, compared to men. Men were more likely to mention cultural, societal and family pressures than women. Robin Hadley, of Keele University, found that 59 percent of men and 63 percent of women said they wanted children. Of the men who wanted children, half had experienced loneliness because they did not have any children, compared with 27 percent of women. Thirty-eight percent of men had experienced depression because they did not have any children, compared with only 27 percent of women. One in four men had experienced anger because they did not have any children, compared with 18 percent of women, while 56 percent of men had experienced sadness because they did not have any children, compared with 43 percent of women. However, no men had experienced guilt because they did not have any children although 16 percent of women had. Mr Hadley said, "My work shows that there was a similar level of wish for parenthood among childless men and women in the survey, and that men had higher levels of anger, depression, sadness, jealousy and loneliness than women. This challenges the common idea that women are much more likely to want to have children than men, and that they always experience all kinds of bad emotions more deeply than men if they don't have children." He carried out his survey of 27 men and 81 women who were not parents using an online questionnaire among people aged 20 to 66, with an average age of 41. Because they didn't have children, half men experienced_.

Have you ever heard your own voice? "Of course," you say. Has anyone else ever heard your voice? Again you say, "Of course."But that's not quite true. Nobody else has ever heard your voice--the way you hear it. When you talk, you set up sound waves . The air outside your head carries the sound waves to your outer ears. But, of course, the sound of your voice begins inside your head. The bones of your head pick up the sound waves, too. They carry the sound waves straight to your inner ears.

Our "Mommy and Me" time began two years ago. My next-door neighbor and fellow mother, Christie, and I were our in our front yards, watching seven children of age six and under ride their bikes up and down. "I wish I could take one of my children out alone," said Christie. Then we worked out a plan. When Christie takes one of her children out alone, I'll watch her other three. And when she watched two of mine, I will take someone out. The children were extremely quick to accept the idea of "Mommy and Me" time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. "She is like a different kid when there's no one else around," Christie shared with me quietly. With her mother all to herself, McKenzie didn't have to make any effort to gain attention. Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I'm always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And the other son, Sam, who is always a follower when around other children, shines a leader during our times together. The "Mommy and Me" time allows us to be simply alone and away with each child--talking, sharing and laughing, which has been the biggest gain. Every child deserves an only child at least once in a while. The author seems to believe that _ .

Gavin Joseph, a teenager with Asperger's Syndrome, was beaten up by a group of people for just being different. Asperger's Syndrome is a developmental disorder that affects a person's ability to socialize. But instead of putting them into prison for what they did to him, Gavin offered them a chance to become more tolerant and understanding. On Thursday night, some kids were talking about how "it's weird " that he is always by himself, attending events alone and watching people, and it was "creepy" that he wanted to be friends with people he didn't know. On Friday night, another kid that overheard that conversation decided to take matters into his own hands and become judge and jury, and this is the result of that. He didn't ask questions, didn't get to know Gavin, never met him, and didn't give him a chance to leave. Gavin was called to meet someone, surrounded by people he didn't know, choked, punched , and left lying on the pavement so he would "learn his lesson". Gavin emerged from the attack with a concussion , a fractured nose, a bruised esophagus and some damage to his eyes, but thankfully, none of the injuries resulted in permanent damage. But here's the truly amazing part -- Gavin refused to press charges against the people who did this to him. Instead of wanting to see them punished, he wants to see them educated. Gavin asked that his attackers do community service that is disability-related. According to his mother, Gavin also asked that they watch a 20-minute video statement he taped while their families were present so they could see the damage they did and hear the event from his perspective. "If you are reading this, I hope you talk to your teens," his mother wrote. "Tell them about disabilities you can't see, teach them to be tolerant of people that are different, teach them that if they continuously see someone alone that maybe it is not their choice to be alone, remind them to ask questions first and get to know one another." We can conclude that Gavin's way of reacting was_.

One day a young man was standing in the middle of the town announcing that he had the most beautiful heart in the whole town. A large crowd gathered, and they all thought it was perfect. There was not a flaw in it. Suddenly, an old man said, "Your heart is not nearly as beautiful as mine." The crowd and the young man looked at the old man's heart. It was full of scars . The young man laughed. "Comparing your heart with mine, mine is perfect and yours is a mess of scars." "Yes," said the old man, "You see, every scar represents a person to whom I have given my love. I tear out a piece of my heart and give it to them, and often they give me a piece of their heart that fits into the empty place in my heart. Though it has some scars, I cherish . Because they remind me of the love we shared. Sometimes I have given pieces of my heart away, and the other person hasn't returned a piece of his or her heart to me. These are the empty gouges . Although these gouges are painful, they stay open, reminding me of the love I have for those people too, and I hope someday they may return and fill the space I have waiting.

Can noncombustion technology create a no-pollution way to drive?Imagine pulling into a service station to fuel up your car. But not at the gas pump or electric battery charger --at the air pump! That's not hot air, either! The next generation of cars may run on thin air. Wouldn't that be an incredible way to cut both pollution and dependence on foreign oil? If you've ever inflated a balloon and then let it go, you've got the basics to test-drive the amazing MiniCAT, currently being developed by Noteur Development International (MDI), headquartered in Luxembourg. Invented by Formula One racing car designer Guy Negre, this experimental vehicle is unlike any car you've ever seen. While your family's traditional car or SUV draws its horsepower using combustion, the only fuel that MiniCAT needs (CAT stands for Compressed Air Technology) is the air we breathe. Start with about 25,000 gallons of air. Now, press it all into a space smaller than your school locker--because that's the size of two super-strong, high-pressure air tanks, made from fiber and fixed beneath the air car. _ that much air inside those small tanks generates an internal pressure of over 4,000 pounds per square inch. That's over 300 times normal air pressure. When this cold, high-pressure air enters MiniCAT's unique engine, it interacts with warmer air to create pressure waves that pump the engine's engineered pistons to move the car. MiniCAT's projected top speed is 60 miles per hour, with a range of 120 miles on a full air supply. What is the passage mainly about?

Six years later, he was badly ill. He has been using a wheelchair since 9 years old. Doctors said he would only live to be 18. After Huang's story went on TV, hundreds of Chinese sent money to help him. The boy was so moved that he decided to thank everyone of them.

Did you know that a turtle can lay 12 eggs in one minute? A large sea turtle lays around 150 eggs at a time. She lays all these eggs in just a few minutes. Large sea turtles live in the warm seas of the world. Except for when they lay their eggs, they spend their whole lives in the water. When it is time to lay their eggs, the females swim to land. They usually return to the place where they themselves were born. How they find their way back there is unknown. When they reach shore, the big, heavy turtles crawl slowly up to the high water mark. Using their flippers, they pull themselves along the sand. They must struggle like mountain climbers. When they finally reach dry sand, they rest before beginning the difficult task of laying eggs. The turtles lay the eggs in deep holes and cover them with warm sand. The sand protects the eggs from harm. Then the females leave them. After a few weeks, if you happened to be walking along the beach, you might see the sand begin to shake. You may see tiny black balls coming out of the sand. The tiny heads of baby turtles!

Everyone is busy nowadays.It's hard to find time for anything.From the time we wake up in the morning until the time we go to bed, it's hard to find 30 minutes to simply be by yourself.If you are married with children, I know you can relate to what I am saying. I would love to have a few days when I come home to an empty house with peace and quiet. There are days when you wish everyone on the other side of the door would simply disappear for about an hour so you can come home and relax without having to start dinner, bathe children, iron clothes for the next day. In fact, finding time to be by yourself is totally necessary if you wish to live a happy, and purpose driven life. If there is noise going on around you it's impossible to hear the quiet voice that speaks inside of us--that guides us and gives us direction on which path we should take and that is no good. Most of the stuff that we need- to get done, does nothing towards our personal development.If you simply let life direct you, you will find that there is never time to take simply for yourself. Yes, you can schedule a vacation every now and then and that is great. No matter how busy your life may be, spend time each day by yourself to think and reflect on life and listen to that inner voice. So by yourself! Go somewhere you won't be disturbed by the children, the _ , the phone, the television, the radio, or your emails.

In traditional Chinese medicine, the body, mind and spirit cannot be divided and so the unique whole-body treatment in Tui Na can also be a useful treatment correcting any imbalances in the body's energy before symptoms and disease can develop. It also works to bring back emotional peace as well as physical health. This is why after a Tui Na treatment many people "feel good". Many people in China use Tui Na regularly to keep healthy and to deal with some specific illnesses. Tui Na is performed on the clothed body and the patient is either lying on a couch or sitting on a chair. Therapists , by using a variety of movements, will control the intensity and direction of pressure in an exact way. The unique rolling movement in Tui Na is one of the most difficult movements to learn and students have to practice sometimes for many months on a rice bag before they are allowed to practice on the human body. Stress Tui Na is of course very useful for treating stress. It spreads the energy around the whole body. It is believed that Tui Na moves the strong energy in the tight muscles to the weaker areas, thus making a more balanced body. When your energy flowing inside your body is balanced, you feel relaxed and comfortable. Tui Na is especially useful for _ shoulders and tight neck muscles. Emotions In Traditional Chinese Medicine each major organ is linked to an emotion. By balancing the energy in the organ, the related emotion will be calmed. When your emotions are out of control, you would usually turn to your doctor or perhaps a psychotherapist . But perhaps some people would not like to be seeing a psychotherapist or feel nervous about discussing their problems with others. With Tui Na, one does not need to tell the therapist anything one does not want to. The treatment of Tui Na can deal with the problem itself. But if one does need to pour out his/her worries or troubles, an active dialogue between the psychotherapist and the patient will help to get a better effect. Organs & Emotions Each major organ -- the heart, the stomach, the liver , the lungs, and etc.--are linked to a relevant emotion. The heart is linked to joy, excitement and sadness. If the heart is out of balance, the patient may dream a lot at night and often forget something important in the day. The stomach is connected with too much thinking or worrying about anxiety. When the stomach is out of balance there is often a lack of energy. The patient often feels very tired and has no interest in doing anything at all. The liver is linked to anger. In Chinese medicine, the eyes are connected with the liver, and many people who suffer from anger often suffer from eye problems. The lung rules decision-making and too much energy here can lead to rashness , while if there is too little, it can bring about indecision. When there is a history of depression with a patient, it may have effect on the liver. ks5u Tui Na can help release most of the discomfort and it is used in almost all the hospitals in China and very popular among Chinese people. It is a useful and valuable method for the balance of your energy flowing, when emotional and physical health is out of balance. Tui Na is one of the remaining secrets of Chinese medicine. When the stomach is out of balance, _ .

Looking for a new weight loss plan? Try living on the top of a mountain.Mountain air contains less oxygen than air at lower altitudes,so breathing it causes the heart to beat faster and the body to burn more energy. Studies have found that athletes training at high altitudes tend to lose weight.Doctor Florian Lippl in Germany wondered how the mountain air would affect _ individuals if they weren't doing any more physical activity than usual. Lippl and his colleagues invited 20 obese men to an environmental research station about 300 meters below the summit of Zugspitze, mountain around 2, meters near the Austrian border.2,970 This was no hiking expedition. They were allowed to eat as much as they liked. men also gave The blood so that researchers could test for hormones linked to appetite and obesity.At the end of the week, men, the whose weight starting out was 105 kilograms, had lost about 1.5 kg on average.The men's blood pressure also dropped,which the researchers owed to weight lost. Exactly what caused the weight loss is uncertain.Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usua!--about 700 calories fewer per day. Appetite loss at high altitudes could certainly be key,notes Damian Bailey,a physiologist, who himself recently lost 11 kg during a 3-month expedition to the Andes in Chile. Unfortunately,for the average person there's no treatment that can resemble living at high altitudes, says Lippl.He says,half-jokingly, obese people plan their holidays,they might not "If go to the sea,but maybe to the mountains." What was found about the 20 obese men in the process of the research?

Qi Haoran, a Junior 1 student at High School Attached to Harbin Institute of Technology, was quite busy over the past winter vacation--and not just with homework. Qi, together with 10 other classmates made a volunteer group to call on people to join the Clean Your Plate Campaign . The 11 students went to many restaurants and told people the importance of saving food."Excuse me, do you know that 950 million people around the world still haven't got enough to eat? Could you please not waste food?"They would say this kind of thing hundreds of times every day. China in recent years has experienced serious problems with wasted food. CCTV reported in January that the food Chinese people waste every year is enough to feed 200 million people for a year. It's a tradition that Chinese people offer lots of food when they invite others to dinner. Many even feel that they will lose face if their guests have eaten all their food. Luckily the campaign has got the support of many. In a restaurant in Xinjiang, the owner gives the guests who have eaten up all that they ordered a sticker. People can enjoy a free meal when they have 10 stickers. More than 750 restaurants in Beijing have begun to offer smaller dishes and encourage their guests to take leftovers home. Wasting food is a serious problem around the world, not only in China. It's said that 2 billion tons of food ends up as waste every year in our country. This is as much as half of all the food in the world. The UN Environment Program and the Food and Agriculture Organization held a"Think, Eat, Save" program on January 24 to help reduce food waste. To reduce food waste is a big task, and it needs time. It's important that everyone does their bit, just like Qi. Did you finish your meals today? The Clean Your Plate Campaign calls on people to _ .

When it comes to problem solving, many of us have heard of the skills of the crow in Aesop's Fables (<<>> ). In the story, a thirsty crow comes across a bottle of water, but the water level is out of its reach. The bird then drops small stones into it until the water level rises enough for the bird to drink. "Oh, it's just a fable," you may think. After all, it's hard to imagine birds knowing about "problem solving". But new research has found that crows' brains may sometimes be better than those of 6-year-old children. In a recent experiment, US scientist Corina Logan and her team caught six crows to test them. There were two tubes of water, one wide and the other narrow . Each crow was given four stones, enough to help them get the water in the narrow tube, but not the wide one. Surprisingly, the crows dropped all or most of the stones into the narrower tube and got the food reward! They had found out the cause-and-effect relationship.Using such brains, crows are making their lives easier. For example, some crows in cities have learned to use road traffic for breaking nuts, National Geographic News reported. But how are their wits compared to humans'? Logan's team did another experiment, this time on both crows and children. Here, the crows and children had to choose between two sets of tubes. With the red set, when they dropped a stone into a wide tube, the water level raised in a connected narrow tube that contained food. The blue set of tubes, however, had no connection between them. So dropping a stone in the wide tube did not cause the water level to rise in the narrow tube. Children aged 7 to 10 were able to learn the rule. Children aged 4 to 6, however, failed. Five of the six crows failed the test. But Kitty, a 6-month-old crow, passed it. She put all or most of the stones into the red tube. So, could a bird be more clever than a kindergartner? Don't be too quick to say no. What have Logan's team found out from their recent experiments?

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." It is clear that _ .

Dozens of dolphins swam out of the polluted waters of Haifa Harbor on Tuesday.This was the first time that dolphins had visited this crowded Mediterranean port,and researchers were surprised and delighted by the unexpected event. Between 40 and 50 of the dolphins appeared in the busy port on Tuesday morning,obviously drawn by the fishrich waters of Haifa Harbor. However,the bay is also full of harmful chemicals. Aviad Sheinin,professor of Haifa University's Maritime Studies Department,said he didn't think the dolphins were harmed by the pollution,but he hoped that they would swim back to the sea soon. "It seems that they are quite relaxed. They don't seem to be stressed," he said. Haifa Harbor is lined by chemical companies that have been pouring poisonous waste into the water for decades. While pollution levels have dropped in recent years,the water is still considered a health hazard. "There are lots of fish in Haifa Harbor. Unfortunately we couldn't tell the dolphins that the fish are not healthy;and I don't know what the result will be," he told Israel Army Radio.Hundreds of Haifa residents gathered around Haifa Harbor to see the interesting sight,and researchers said this provided a rare chance to film and study the roughtoothed dolphins. In addition to the dozens of dolphins which swam into the port on Tuesday,a similar number stayed outside the breakwater .Later Tuesday the dolphins left the port but remained near the entrance and Israel's coast guard was patrolling the area to try to make sure the dolphins didn't reenter the poisonous waters. Relatively little is known about roughtoothed dolphins,which are usually found in deep and warm tropical waters. Aviad Sheinin's words suggest that _ .

The day I became a mom was not the day my daughter was born, but seven years later. Up until that day, I had been too busy trying to survive my abusive marriage. I had spent all my energy trying to run a "perfect" home that would pass inspection each evening, and I didn't see that my baby girl had become a toddler. I'd tried endlessly to please someone who could never be pleased and suddenly realized that the years had slipped by and could never return. Oh, I had done the normal "motherly" things, like making sure my daughter got to ballet and gym lessons. I went to all of her recitals and school concerts, parent-teacher conferences and open houses alone. We suffered from my husband's rages when something was spilled at the dinner table, telling her, "It will be okay, Honey. Daddy's not really mad at you." I did all I could to protect her from hearing the awful shouting and complaints after he returned from a night of drinking. Finally I did the best thing I could do for my daughter and myself: I removed us from the home that wasn't really a home at all. That day I became a mom was the day when my daughter and I were sitting in our new home having a calm, quiet dinner just as I had always wanted for her. We were talking about what she had done in school and suddenly her little hand knocked over the full glass of chocolate milk by her plate. As I watched the white tablecloth and freshly painted white wall become dark brown, I looked at her small face. It was filled with fear, knowing what the consequence of the event would have meant only a week before in her father's presence. When I saw that look on her face and looked at the chocolate milk running down the wall, I simply started laughing. I am sure she thought I was crazy, but then she must have realized that I was thinking, "It's a good thing your father isn't here!" She started laughing with me, and we laughed until we cried. They were tears of joy and peace and were the first of many tears that we cried together. That was the day we knew that we were going to be okay. Whenever either of us spills something, even now, seventeen years later, she says, "Remember the day I spilled the chocolate milk? I knew you had done _ for us." That was the day I really became a mom. I discovered that being a mom isn't only going to ballet or gym, recitals, and attending every school concert and open house. It isn't keeping a tidy house and preparing perfect meals. It certainly isn't pretending things are normal when they are not. For me, being a mom started when I could laugh over spilled milk. Why did the author and her daughter laugh and then cry?
|
[
"Because it was a thorough relief after they had suffered too much.",
"Because they were actually crazy.",
"Because they wouldn't see the abusive man any more.",
"Because spilling the chocolate milk on the wall was really funny."

Surgeons in Spain have successfully carried out the world's first organ transplant using new stem cell technology. Some people are calling it the greatest medical breakthrough so far this century. But what are stem cells? As we know, most cells in our bodies are designed to serve specific purposes - for example, a liver cell develops to work in the liver and cannot become a heart cell. But stem cells are different. They are very young, and in the laboratory scientists can grow them into different types of cell. Claudia Castillo needed a new windpipe after getting a serious disease. Scientists from the University of Bristol in the UK took a donor windpipe, or trachea, from someone who had recently died. They used strong chemicals to remove the donor's cells, leaving a tissue scaffold . This was refilled with cells from Ms Castillo's windpipe, and stem cells from her bone. After four days the cells had grown sufficiently for the windpipe to be transplanted into Ms Castillo. Currently, transplant patients have to take drugs for the rest of their lives to prevent their bodies rejecting the new organs. These drugs can have bad side-effects, and do not always prevent rejection. But by using Ms Castillo's own cells, doctors were able to trick her body into thinking the new windpipe was her own organ. Five months on, Claudia Castillo is in perfect health. This ground-breaking procedure could be used in other transplant operations in the future. Scientists also believe stem cells might be used to treat Parkinson's disease, Alzheimer's disease, heart disease, stroke, arthritis, diabetes, burns and so on. However, stem cell research is extremely controversial. The most effective stem cells do not come from adults but from embryos created in laboratories and which are just a few days old. Many people have religious or ethical objections to growing embryos, even if they can be used to cure diseases. Which word can best describe the scientists' attitude towards the stem cell technology?

Most children have heard their parents at one time or another yell "sit up straight!" or "don't slouch!" In the past, this was usually heard at the dinner table as children ate dinner. But these days, it is also heard around another activity-video games. Ten-year old Owaish Batliwala, from Mumbai, India, admits he spends three to four hours each day playing games on his tablet computer. His mother Mehzabin became concerned when her son started saying that his neck hurt. She said, "My son started having neck problems around June or July. The pain slowly spread to his hand and his back. He plays for hours on the iPad and mobile phone. This is what has caused the problem." Sadia Vanjara is a physical therapist. She says the number of young children with chronic pain in their necks, arms and shoulders is on the rise. Dr. Vanjara says the pain is not from aging, accidents or disease. It is from poor posture, or body position, while playing video games. "They are not aging, they haven't had an accident, their age is like, under 10, they are not complaining, the blood reports are fine, their x-rays are fine, their MRI's are fine, then where is the culprit ? And that is the very common thing that is happening amongst all children and that is smart phones and the gadgets ." This is a problem in many parts of the world. But there are more smartphone users in India than anywhere else in the world, except China. Networking equipment company Cisco estimates that the number of smartphone users in India will increase from 140 million today to 651 million by 2020. 19-year old student Nida Jameel says she feels pain in the finger which holds the weight of her smartphone most of the day. She says she uses her smartphone 24/7. This means 24 hours a day, seven days a week, or all the time. "As I use phone 24/7 (all day) like, so probably yeah, it was because of the phone, continuous usage and Snapchat, Whatsapp, more and more you know social media coming, so like phone is the center of everything." Dr. Vanjara says the best treatments for the pain are daily exercises. "And start stretching it in all the possible directions that you can." Correct posture can help prevent pain. Dr. Vanjara teaches children how to hold their gadgets correctly. She tells a patient to hold the gadget in front of the face. She says that bending the head down to look at the device, strains the neck and creates an unhealthy bend to the back. Sadia Vanjara predicts we will see not only physical but psychological and emotional problems resulting from overuse of gadgets. Experts advise taking breaks from using a computer or other device often. Stand up. Stretch your legs, back, shoulders and arms. And when your work or school work is done, unplug and exercise.

Dear editor, Several days ago, I heard that a dear friend of mine had killed herself. I was deep in sorrow by the sudden news. I can't keep calm any longer. I'm always thinking about life and death. Life is so precious. If we can slip into death in an impulsive moment, what use in all our efforts and hopes? Our families, our ambitions, everything is flung into total darkness. And death allows no time for regret. Nevertheless, the suicide rate increases year by year, particularly of young people. Reasons may vary from person to person, yet I think they share something in common. First, today's young people are morally weak. They hunger for success but can not face failure; they are eager to be understood but afraid of opening their hearts to others. They live in a wide world, from east to west, ancient to present, but their hearts beat in a narrow desert, closed tight, unable to communicate. Each becomes an isolated fortress , lonely, and weak. My friend is a good example of that. As a young teacher, she was devoted to her work but was disappointed with her students' occasional failures. She fell in love with a colleague but he deserted her. With no close friends, disappointed at work and in love, death seemed to her the only remaining choice and she took it. Another reason for the weakness of today's youth, in my opinion, comes from society's pressures. The young are forced to try too hard to succeed. On the other hand, society refuses to accept that children sometimes do fail. But failure is more important because it can teach the young how to win next time. What can we do to save the desperate young? The passage wants to tell us_.
|
[
"a lot of young people choose death to escape from the society",
"the number of people who take suicide is larger and larger",
"the young people should go to see doctors to solve the spiritual problems",
"the reason why the young kill themselves lies in two main kinds"

Sleep is a basic human need, as basic as the need for oxygen. Getting a good night's sleep is not only directly related to how we feel the next day, but to our long-term health as well. However, many of us suffer from insomnia . Even more odf us report at least one night of restless sleep per week. This is a serious problem. Well, how can we make sure that we rest well and stay healthy? Here are some suggestions. If you can't sleep in the middle of the night, don't get up. The bright light will affect your body clock and worsen your insomnia. Stay in bed! Avoid short sleep during the day, except for a brief ten to fifteen-minute sleep between 2:00 and 4:00 P.M. Limit your time in bed to the average number of hours you 've actually slept per night last week. Don't try to make up for lost sleep. It can't be done. Get regular exercise each day, but finish at least six hours before bedtime. Exercising in the evening can help keep you awake. Take a hot bath for thirty minutes within two hours of bedtime. The bath will warm you, relax you, and make you feel sleepy. Keep our bedroom dark, quiet, and well ventilated . Keep a regular schedule seven days a week. Avoid sleeping late on weekends. Although it may feel good while you're doing it, sleeping late on weekend can lead to insomnia during the week. Don't drink alcohol . Although, having a drink before bed makes you sleep, alcohol loses its effects after a while. The secondary effects of alcohol can wake you up during the second half of your night's sleep. Keep the face of the clock in your bedroom turned away, and don't find out what time it is when you awaken in the night. Which of the following is NOT advised for a good night's sleep?
|
[
"Don't exercise six hours before sleeping.",
"Preventing the wind from blowing into your room.",
"Staying in bed after failing to sleep.",
"Don't drink alcohol before sleeping."

Nowadays, many children spend hours a day looking at computer screens or other digital products. Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome . Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. "More children come into my office because their parents have noticed that they have headaches or red eyes, or because their degree of short-sightedness appears to be increasing very fast and they're worried," he said. Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don't tell their parents, because they don't want their games or the computer to be taken away. Another part of the problem is that people blink less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally do in everyday life. If eyes can't stay wet or are too tired, they will not be protected like normal. Why don't some children tell their parents when their eyes start to feel uncomfortable?

How old is "old"? The answer has changed over the years.Two hundred years ago, you were old at 35.At the beginning of the 20th century, the average life span was 45.In 1950,70-year-olds were really old.Today, a healthy 70-year-old person is still thought young. So, how old is old? The answer is one you've heard many times, from all kinds of people."You are as old(or young) as you feel." Your age simply tells you how many years you have lived.Your body tells you how well you've lived. "Nobody grows old by living a number of years," wrote a writer."People grow old when they don't have their ideals ." People should not have the wrong ideals about aging.Sometimes, old minds can be as bright as young minds.Alice Brophy once said, "It makes me happy who people say.You look young for your age." What does that mean? You know you can die old at 30 (30) and live young at 80. Which question is NOT answered in the passage?

Remember, from the moment they are born, our children have the ability to know when they are hungry - and they cry to let us know too! Of course, they also cry to let us know they are wet, hurt, or bored, but we soon learn to tell the difference and try to meet each need somehow. When we begin to feed them solid foods, they let us know when they have had enough by turning away from the spoon - or refusing the food back at us! Why is it that once children are old enough to sit at the table their parents are often heard bargaining with them or threatening them to finish all their dinner? When we make our children eat up the plate that we filled, we don't pay attention to their born ability to know how much, and what, their bodies need. Instead, we should allow them to use their own hunger feelings to determine how much they need, while we provide a balance of nutritious and "fun" foods. When we teach them about moderation and set a great example by living an active, healthy lifestyle, they will be less likely to develop weight problems later in life. Think of your slim friend who eats whatever she wants -but will refuse ice cream if she has had enough to eat! "Eat all your dinner if you want dessert" translates to "you must overeat so I will reward you by letting you overeat some more!" By using sweets as a reward for good behavior, kids begin to believe sweets are really special and they may want them even more. Instead, by making dessert just another (small) part of an enjoyable meal, kids learn to "save room for dessert" instead of becoming a member of the "clean plate club." The next passage may tell us _ .

When we hear the words "college students", we usually think of a young person between 18 and 22 years old. But in the U.S.A today, a college student often is much older. In fact, educators say in the next few years colleges and universities may have more older part-time students than traditional full-time younger students. Educators report a big increase in the number of Americans who attend college and university classes in the evening or at night or weekends. Most of them are older than 25 years old and more have full-time or part-time jobs. Many are in their thirties or forties. Why are so many people deciding to spend their time and money in order to continue their education? Most are doing it because they believe more education will help them to get a better job. Some are industrial workers whose factories have closed. They are learning new skills to prepare for other kinds of work. Some of the part-time students are not pleased with the jobs they have. They are studying for new ones. Some have retired and are looking for new kinds of work. Two of every three of the students older than 35 are women. Many of them are returning to school after years of staying at home to care for children. Are older students good students? Most teachers say yes. They say older students really want to learn. They ask difficult questions and are not pleased with simple answers. They often get high grades. They often get high grades" means _ .

Doctors' moonlighting is becoming popular in hospitals around China. It has not only raised a lot of heated discussions in the media, but also caught the attention of the central government in Beijing. On December 26, a spokesman of the Ministry of Health stressed that the ministry was firmly against doctors' moonlighting, while strict regulations should be applied to doctors taking part-time jobs, the Xinhua News Agency reported. Last year, the Ministry sent out a notice to a variety of health organizations to speed up the reform of their personnel system. According to the notice, medical organizations can hire medical experts as part-time doctors but such activities should take place under the hospital's management and regulations . As for moonlighting--meaning that the doctor provides medical service without the permission of the original hospital--such activity goes against China's Practicing Doctor Law, Xinhua reported. In China, doctors used to be controlled by hospitals and they could work for only one hospital. However, as China's medical personnel system reform developed, it has been recognized that medical human resources, just like human resources in other areas, should be shared by the whole society. But on the other hand, doctors' taking part-time jobs should follow the relative regulations applied in the medical field. First of all, they should follow relative government laws and regulations. They should also follow the rules and regulations set by the medical organizations they work for. In addition, they should pay taxes for their income from the part-time jobs. What matters most is that they should first finish their regular jobs as required and be responsible for patients to ensure qualified and safe medical treatment. From this passage we know that doctors are allowed to _ nowadays.

Speeding off in a stolen car, the thief thinks he has got a great catch.But he is in for an unwelcome surprise.The car is fitted with a remote immobilizer, and a radio signal from a control centre miles away will ensure that once the thief switches the engine off, he will not be able to start it again. The idea goes like this.A control box fitted to the car contains a mini-cellphone, a micro-processor and memory, and a GPS satellite positioning receiver.If the car is stolen, a coded cellphone signal will tell the control centre to block the vehicle's engine management system and prevent the engine being restarted. In the UK, a set of technical fixes is already making life harder for car thieves." ," says Martyn Randall, a security expert.He says it would only take him a few minutes to teach a person how to steal a car, using a bare minimum of tools.But only if the car is more than 10 years old. Modern cars are far tougher to steal, as their engine management computer won't allow them to start unless they receive a unique ID code sent out by the ignition key.In the UK, technologies like this have helped achieve a 31% drop in vehicle-related crime since 1997. But determined criminals are still managing to find other ways to steal cars, often by getting hold of the owner's keys.And key theft is responsible for 40% of the thefts of vehicles fitted with a tracking system. If the car travels 100 metres without the driver confirming their ID, the system will send a signal to an operations centre that it has been stolen.The hundred metres minimum avoids false alarms due to inaccuracies in the GPS signal. Staff at the centre will then contact the owner to confirm that the car really is missing, and keep police informed of the vehicle's movements via the car's GPS unit. The operations centre will first _ after receiving an alarm.

American nutrition expert Professor Barry Popkin says that the number of overweight people in the world is now bigger than the number of people who don't have enough to eat. A billion people worldwide now weigh too much and the number of obese people is now more than 300 million. "Obese" means at least 15 kilos heavier than you should be. However, there are also 800 million people in the world who don't have enough to eat. Professor Popkin says that the number of hungry people is falling slowly but the number of overweight people is rising fast. The main reasons for this are: * People are doing less hard physical work * More people worldwide now eat too much fatty food * Too many people are driving cars instead of walking * People spend too much time in front of a television The United States has the highest rate of obesity in the developed world and Japan has the lowest. Professor Benjamin Senauer is absolutely certain of the reasons for this. "Japanese people are fit. They use public transport and walk," he said. "The average American drives to work and drives to supermarket. When he gets home, he sits on a couch in front of the TV and eats junk food." In Britain and many other European countries, there are three times as many obese people as there were 20 years ago. About two thirds of British adults are overweight or obese. "The effects of this are clear," said London doctor Elena Power. "We have more illnesses related to weight and fewer fit people. China used to be one of the slimmest nations in the world. However, Professor Wu Yangfeng from the Chinese Academy of Medical Sciences in Beijing recently estimated that 20 percent of the world's overweight people live in China. The Chinese government is especially worried about the increase in obesity among schoolchildren. "We have a serious problem," said Professor Wu. "It requires an improvement from everyone, or it will get worse. What does the writer try to tell us in the passage?

I've just got to talk about this problem I'm having with my postman. It all began a year ago, after the birth of his first child. Not wanting to appear rude, I asked him about the baby. The next week, not wanting him to think I had asked out of mere politeness the week before, I asked all about the baby again. Now I can't break the habit. I freeze whenever I see him coming. The words "How's the baby?" come out on their own. It holds me up. It holds him up. So why can't I stop it? The answer is that I want him to like me. Come to think of it, I want everyone to like me. My sister had the same problem with the caretaker of her block of flats: "All he ever does is complain; he talks at me rather than to me, never listens to a word I say, and yet for some reason I'm always really nice to him. I'm worried in case I have a difficulty one day, and he won't lift a finger to help." What about at work? Richard Lawton, a management trainer, warns: "Those managers who are actually liked by most of their staff are always those to whom being liked is not the primary goal. The qualities that make managers popular are being honest with staff, treating them as human beings and observing common politeness like saying hello in the morning." To explain the point, Richard mentions the story of the company chairman who desperately wanted to be liked and who, after making one of his managers fired, said with moist eyes that he was so, so sorry the man was leaving. The employee replied: "If you were that sorry, I wouldn't be leaving." The lesson being, therefore, that if you try too hard to be liked, people won't like you. The experts say it all starts in childhood. "If children feel they can only get love from their parents by being good," says Zelda West-Meads, a marriage guidance consultant, "they develop low self-confidence and become _ ." But is there anything wrong in being a giver, the world not being exactly short of takers? Anne Cousins believes there is. "There is a point at which giving becomes unhealthy," she says. "It comes when you do things for others but feel bad about it." I am now trying hard to say to people "I feel uncomfortable about saying this, but..." and tell myself "Refusal of a request does not mean rejection of a person" and I find I can say almost anything to almost anyone. What is the author's intention of writing this passage?

Most young boys don't like growing flowers and watering them. But for 16-year-old Angus,working in the garden isn't just a hobby -- it has changed his life. Angus has a special illness and his IQ is lower than a normal boy. Six months ago, he started learning how to grow flowers. Now, he spends hours in the garden growing flowers, watering and looking after them. "Before working in the garden, it was difficult for Angus to concentrate inclass and sometimes he didn't want to go to school," said his mother Kim. "Now he can't wait togo to school and he is happy every day. We can see Angus is able to work in a garden center in thefuture," Research shows that working in the garden improves mental and physics health. In the past,soldiers in Egypt treated their mental problems after war by working in the garden. Even now,some doctors advise people to work in the garden to treat their mental health problems. Anddoctors also advise young people like Angus to work in the garden. The lives of hundreds of children in Britain with special needs, like Angus, have beenchanged by this special kind of education. When working in the garden, children have a chance tolearn a lot of important skills, such as how to work with other people and how to take care ofplants. Besides, the children become more confident after working in the garden. Which of the following is TRUE about working in the garden?

Earlier, we explained how to begin a search for schools by going to one of the American educational advising centers around the world. We also discussed the rules for entering in the prefix = st1 /United States. And we talked about programs that can be completed online. But if your goal is to come to the United Statesto study, then it is time to make a list of colleges or universities that interest you. Be sure to choose more than one. Directors of foreign student admissions say students should apply to at least three schools. Some students want to attend a small college. Others want to go to a big university. If a really big university appeals to you, then there are ones like _ State. That university in Columbus, Ohio, in the Midwest, has almost fifty - two thousand students. There are students this year from around one hundred fifty countries. Ohio State provides international students with an application on its Web site. You can pay the application charge online with a credit card. Or you can print the forms and mail them with the payment. Many colleges and universities have their applications and also their catalogs online. You should start on your applications at least two years before you want to begin studies. Completing a college application can take some time. But answering all the questions is not enough. Another important step is taking admissions tests. The SAT is the college entry test that American high school students most commonly take. Another one is the ACT. Colleges and universities may also require international students to take the TOEFL - the Test of English as a Foreign Language. If you have a general question for our Foreign Student Series, write, to special @ voanews. com. What will the author most probably talk about next?

Make the most of college Dear Daughter, As we drove off from Columbia, I wanted to write a letter to you to tell you all that is on my mind. First, I want to tell you how proud we are. Getting into Columbia is a real testament of what a great well-rounded student you are. You should be as proud of yourself as we are. Your college years will be the most important of your life. It is in college that you will discover what learning is about. This will be the period where you go from teacher-taught to master-inspired, after which you must become self-learner. So do take each subject seriously, and even if what you learn isn't critical for your life, the learning skills you acquire will be something you will cherish forever. Follow your passion in college. Take courses you think you will enjoy. Don't be trapped by what others think or say, but make up your own mind. Most importantly, make friends and be happy. College friends are often the best in life. Pick a few friends and become really close to them - pick the ones who are genuine to you. Don't worry about their hobbies, grades, looks or even personalities. Start planning early - what would you like to do? Where would you like to live? What would you like to learn? I think your plan to study fashion is good, and you should decide where you want to be, and get onto the right courses. Whether it is summer-planning, or coursework planning, or picking a major, or managing your time, you should take control of your life. I will always be there for you, but the time has come for you to be in the driver's seat - this is your life, and you need to be in control. Being in control feels great. Try it, and you'll love it! College is the four years where you have: l The greatest amount of free time l the first chance to be independent l the most flexibility to change l the lowest risk for making mistakes So please treasure your college years - make the best of your free time, become an independent thinker in control of your destiny, be to experiment, learn and grow through your successes and challenges. May your years at Columbia be the happiest of your life, and may you blossom into just what you dream to be. Love, Dad (&Mom) What does the author advise his daughter to do in college? _

"I sometimes get up at three or four in the morning and I surf the net." "I often check my e-mail forty times a day. " "I often spend more than three hours during one time on the net." "I spend more time in chat rooms than with my 'real-life' friends." Do you know any people like these? They are part of a new addiction called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug use. People lose control of the time they spend on the Internet. For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight. Studies show that about 6% to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them. They spend more time in cyberspace than in the real world of friends and family. Is "surfing the net" a hobby or an addiction for you? You may have a problem if you have these symptoms : 1You do not go to important family activities or you do not do school work because you like to spend hours on the Internet. 2You can't wait for your next online time. 3You go out with your friends less and less. 4You plan to spend a short time online, but then you spend several hours. How does the writer describe the addicts' use of Internet?

Space is a dangerous place, not only because of meteors but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is necessary for plants to make the food that we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage. Radiation is the greatest known danger to explorers in space, The unit of radiation is called "rem" Scientists have reason to think that a man can put up with far more radiation than 0.1rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage. A person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of _ children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and , during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far. It can be inferred from the passage that _ .

Teaching and research are supported by the University's extensive collections--the Yale University Art Gallery, the Yale Center for British Art, the Peabody Museum of Natural History, and the Collection of Musical Instruments. All the collections are open to the public. Yale University Art Gallery The Yale University Art Gallery, founded in 1832, today houses a collection that has grown to rank with those of the major public art museums in the United States. Its two connected buildings house ancient, medieval, and Renaissance art, Near and Far Eastern art, archaeological material from the University's excavations , Pre-Columbian and African art, works of European and American masters from actually every period, and a rich collection of modern art. Across the street, the Yale Center for British Art, which was opened in 1977, holds the largest collection of British art and illustrated books anywhere outside the United Kingdom. Peabody Museum of Natural History Yale's Peabody Museum of Natural History, founded in 1866, contains one of the great scientific collections in North America. Among its holdings are the University's comprehensive mineralogical and ornithological collections, the second-largest repository of dinosaur artifacts in the United States, and the largest undamaged Apatosaurus (Brontosaurus ) in the world. The Peabody is truly a working museum, where public exhibition, research, conservation, teaching, and learning intersect . Yale Center for British Art Institutions like the Art Gallery, the Center for British Art, and the Peabody Museum hold only a portion of the treasures in the University's collections. From paintings by Picasso, to pterodactyl remains, to a 1689 tenor viol in the Collection of Musical Instruments, Yale's possessions are meant to be accessible to the communities they enrich. Collection of Musical Instruments Exhibitions are also frequently mounted at the following venues on campus: Art + Architecture Gallery (School of Architecture), Beinecke Rare Book and Manuscript Library, Green Hall Gallery (School of Art), and Sterling Memorial Library, including the Arts of the Book Collection.

Traffic Management Traffic lights are key tools for regulating traffic How.They are not, however, perfect.Drivers exchange the traffic jams that would happen at unmanaged crossings for a pattern of stop-go movement that can still be annoying, and which bums more fuel than a smooth passage would. Creating such a smooth passage means adjusting a vehicle's speed so that it always arrives at the lights when they are green.That is theoretically possible, but practically hard.Roadside signs wired to traffic lights can help get the message across a couple hundred metres from a crossing, but such signs are expensive, and are not widespread.Margaret Martonosi and Emmanouil Koukoumidis at Princeton University, and Li-Shiuan Peh at the Massachusetts Institute of Technology, however, have an idea that could make the process cheaper and more effective.Instead of a hardwired network of signs, they propose to use mobile-phone applications. For a driver to benefit, lie must load the team's software , named SignalGuru, into his phone and then put it on a special thing attached to the inside of his car's windscreen, with the camera lens pointing forward.SignalGuru is designed to detect traffic lights and track their status as red, yellow or green.It broadcasts this information to other phones in the area that are fitted with the same software, and --if there are enough of them ?the phones thus each know the status of most of the lights around town.Using this information, SignalGuru is able to calculate the traffic-light schedule for the area and suggest the speed at which a driver should travel in order to avoid red lights. Tests in Cambridge, Massachusetts, where five drivers were asked to follow the same route for three hours, and in Singapore, where eight drivers were asked to follow one of two routes for 30 minutes, revealed that SignalGuru was capable of predicting traffic-light activity with an accuracy of 98.2% and 96.3% respectively, in the two cities.This was particularly impressive because in Cambridge the lights shifted, roughly half-way through the test, from their unbusy schedule to their afternoon-traffic schedule, while in Singapore lights are adaptive, using detectors fixed under the road to determine how much traffic is present and thus when a signal should change.In neither case was SignalGuru fooled. Fuel consumption fell, too --by about 20% .SignalGuru thus reduces both annoyance and fuel use, and makes going back and forth to work a slightly less horrible experience. SignalGuru is an application used on _ .

Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need. It has been demonstrated that rats will, when given a choice over a period of time, prefer water with vitamins to water without vitamins even though there is no difference in taste or smell between the two water bottles. When a fragrant flavor was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water. In time, however, they broke _ and went back to where the necessary vitamins were. In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria feeding arrangement, with a wide selection of baby food before them. They were given whatever food they pointed to or appeared interested in. We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet. So, in selecting food, rats and babies do seem to know and act on what's best for them. Apparently, there is a kind of "body wisdom", which humans soon lose. Most of us do not eat as wisely as we could. Many of our food preferences are culturally determined and influenced by long-established habits. Some people eat fox, dog and blackbirds, while we eat cows and pigs. So what people eat and how much they eat seems to be greatly influenced by what is going on around them. The author implied in the passage that most of us _ .
