There are various ways in which individual economic units can interact with one another. Three basic ways may be described as the market system, the administered system, and the traditional system. In a market system individual economic units are free to interact among each other in the marketplace. It is possible to buy commodities from other economic units or sell commodities to them. In a market, transactions may take place via barter or money exchange. In a barter economy, _ goods such as automobiles, shoes, and pizzas are traded against each other. Obviously, finding somebody who wants to trade my old car in exchange for a sailboat may not always be an easy task. Hence, the introduction of money as a medium of exchange eases transactions considerably. In the modern market economy, goods and services are bought or sold for money. An alternative to the market system is administrative control by some agency over all transactions. This agency will issue commands as to how much of each good and service should be produced, exchanged, and consumed by each economic unit. Central planning may be one way of administering such an economy. The central plan, drawn up by the government, shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. This is an example of complete planning of production, consumption, and exchange for the whole economy. In a traditional society, production and consumption patterns are governed by tradition; every person's place within the economic system is fixed by parentage, religion, and custom. Transactions take place on the basis of tradition, too. People belonging to a certain group or caste may have an obligation to care for other persons, provide them with food and shelter, care for their health, and provide for their education. Clearly, in a system where every decision is made on the basis of tradition alone, progress may be difficult to achieve. An inactive society may result. Which of the following is not mentioned by the author as a criterion for determining a person's position in a traditional society?

Dear Customers, I love slipping into a comfortable chair for a long read--as I relax into the chair, I also relax into the author's words, stories and ideas. The physical book is so elegant that it disappears into the background, and what remains is the author's world. Today, we at Amazon are excited to announce Mindle, a wireless, portable reading device with instant access to more than 90,000 books, magazines and newspapers. We've been working on Mindle for more than three years. Our top design objective was for Mindle to disappear in your hands--to get out of the way--so you can enjoy your reading. We also wanted to go beyond the physical book. Mindle is wireless, so whether you're lying in bed or riding a train, you can think of a book, and have it in less than 60 seconds. No computer is needed--you do your reading directly from the device. We chose the same wireless technology used in advanced mobile phones. But unlike mobile phones, there are no monthly wireless bills, no service or data plans, and no yearly contracts. There is no software to install (,). We want you to get lost in your reading and not in the technology. Mindle uses a new kind of display called electronic paper. Sharp and natural with no strong light, reading on Mindle is nothing like reading from a computer screen. Mindle weighs only 10.3 ounces--less than paperback--but can carry two hundred books. Enjoy learning about Mindle and many thanks! Jeff Bezos Founder & CEO With the device, the reader is able to _ .

EBay will launch an online group gift-buying service today designed to make it easier for several people to chip in, buy and pay for gifts using their social-network and e-mail contacts. EBay North America Vice President Christopher Payne says it is going to be a major step forward in social commerce, which is the still-small practice of selling products through social networks.Online retail experts aren't as certain, but eBay says the new tool makes it easier for friends and relatives to chip in for gifts because it eliminates the headache of collecting contributions.It can also be used for family members to pitch in to buy, say, an expensive child seat for a mother. Anything on eBay that's available immediately, rather than up for bid, can be purchased this way starting today atgroupgifts.eBay.com.If members of an extended family wanted to buy a gift for one member, one person would choose a gift -- or have one recommended by eBay -- and invite family members to chip in using Facebook or e-mail.Those who wanted to join in would choose an amount to contribute (or agree to pay a requested amount) and pay using either PayPal or a credit card.They could also add a personal note. If enough people don't chip in, the organizer can ask people to contribute more or choose a less expensive gift. "I see myself using this most in cases when I typically might not buy someone what they want because of price," says Nitzan Shaer of Boston, who was part of an online test of the site. EBay, with its 200 million products, millions of sellers and mobile commerce proficiency, is a logical place to pull together the products, groups of buyers and payment tools, Payne says. At least 12 sites, such as FrumUs.com and eDivvy.com, facilitate (,) group purchases but don't sell products.Although a handful of retailers, including Victoria's Secret and 1-800-Flowers, sell products through Facebook, Payne says he expects social commerce will take off as rapidly as shopping using mobile devices.EBay did more than $600 million in sales on mobile devices last year and expects mobile sales to increase to $1.5 billion this year. Although one in five consumers surveyed said they'd used Facebook for shopping in the past year, 88% said they would not be buying holiday gifts through a social network, mobile phone or smartphone.Of these, 26% were reluctant because of security or privacy concerns, and 20% were unclear about the benefits of using phones or Facebook to shop.

As we know, it is common for people to catch a cold in winter and most people believe they know the reason for colds. However, scientists say people have some wrong beliefs about the cause of colds. Many people think that once you get infected by colds, you will not be easy to be attacked by colds for the rest of your life. That's not the case. There are about 200 different viruses that cause the common cold. You catch a cold because of one kind of them this time, but you might catch a cold next time because of another. Others believe that people get sick just because of the cold weather in winter. That is also wrong. It's because people tend to stay closer in winter and the cold virus is _ from one person to another through handshakes, sneezing, or coughing. While there is no actual cure for the common cold, scientists say there are still a few things you can do to help you. Some experts say honey and chicken soup are effective against colds. Especially honey. There is increasing evidence that it helps shorten the duration of the common cold sometimes even by two to three days particularly in children. Chicken soup also helps reduce the duration of the cold. In addition, if you do have a cold and you don't feel like eating anything, it's not going to hurt you but you have to drink a lot and you can drink water or tea because doctors say the water cycle in your bodies helps to cure colds. That's very important. Though there is more than one way to deal with colds, doctors say the best advice is to continue using whatever works best for you. If you have a cold, you can do the following except _ .

Food safety will become the food industry's key target as the nation tries to adopt international food standards. The National Development and Reform Commission, the Standardization Administration of China, the Ministry of Agriculture and six other departments announced their 2004-05 development programme for national food standards over the weekend. China is conducting a rectification within two years. Inspectors will search for all known banned materials in food production. To reduce trading barriers, China will raise the ratio of adopting international standards in the food industry to 55 percent from today's 23 percent. "Safety is the first consideration for anything entering people's mouth followed by its nutritious value," said Hao Yu, secretary-general of the National Food Industry Standardization Technique Committee. He added the usage of food addictives will be a major field for consideration in setting the new standards. On-the-spot checks during the past two years have shown the abuse or misuse of addictives in food production and processing has become the biggest threat to food safety. In one case, talcum powder was found in flour products, which is outlawed according to national food standards. "At present there are no methods or standards to test the content of talcum powder in flour," said Shang Yan'e, an official with the national watchdog on grain and oil inspections. Under the guidelines, all banned addictives will be recorded as inspections increase, Relevant departments have allocated funds to conduct risk evaluations on current food addictives to fix the limits of their usage. China will adopt international advanced techniques and standards so as to find out the harmful materials in food within a shortest period. China will raise the ratio of adopting international standards in the food industry by _ .

Learning disabilities are very common. They affect perhaps 10 percent of all children .Four times as many boys as girls have learning disabilities. Since about 1970, new research has helped brain scientists understand these problems better. Scientists now know there are many different kinds of learning disabilities and that they are caused by many different things. There is no longer any question that all learning disabilities result from differences in the way the brain is organized. You cannot look at a child and tell if he or she has a learning disability .There is no outward sign of the disorder .So some researchers began looking at the brain itself to learn what might be wrong. In one study ,researchers examined the brain of the learning-disabled person who had died in an accident .They found two unusual things. One has something to do with cells on the left side of the brain ,which control language. These cells normally are white .In the learning-disabled person, however ,these cells were gray. The researchers also found that many of the nerve cells were not in a line the way they should have been .The nerve cells were mixed together. The study was carried out under the guidance of Norman Geschwind, an early expert on learning disabilities. Doctor Geschwind thought that learning disabilities resulted mainly from problems on the left side of the brain .He believed this side of the brain failed to develop normally .Probably ,he said ,nerve cells there did not connect as they should .So the brain was like an electrical device in which the wires were crossed. Frank Duffy experimented with this technique at Children's Hospital Medical Center inprefix = st1 /Boston. Doctor Duffy found large differences in the brain activity of normal children and those with reading problems. The differences appeared throughout the brain. Doctor Duffy said his research proves that reading disabilities result from damage to a wide area of the brain, not just the left side. It is NOT mentioned in the passage that learning disabilities may result from_.

Global Positioning Systems are now a part of everyday driving in many countries. These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But, they can also cause a lot of problems, send you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two. We spoke to Mr. Brown by Skype. He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay. Barry Brown: "And they just plugged in an address and then set off to their destination. And, then it wasn't until they were driving for thirty minutes that they realized they actually put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of 'garbage in garbage out'." Mister Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment. Barry Brown: "One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place." Barry Brown formerly served as a professor with the University of California, San Diego. While there, he worked on a project with Eric Laurier from the University of Edinburgh. The two men studied the effects of GPS devices on driving by placing cameras in people's cars. They wrote a paper based on their research. It is called "The Normal, Natural Troubles of Driving with GPS." It lists several areas where GPS systems can cause confusion for drivers. These include maps that are outdated, incorrect or difficult to understand. They also include timing issues related to when GPS commands are given. Barry Brown says to make GPS systems better we need a better understanding of how drivers, passengers and GPS systems work together. With which of the following statement would Barry Brown most likely agree?
|
[
"GPS units are to blame for the most GPS service failures.",
"We should introduce higher standard for the driving license.",
"Cameras are urgently needed to help improve GPS systems.",
"Drivers, GPS systems and passengers should unite to improve GPS systems."

Four students compared the total mass of the products to the total mass of the reactants after performing three trials of the same chemical reaction. Each student concluded that the total mass of the products was slightly less than the total mass of the reactants. Each student proposed a different explanation as follows. Student 1: The reaction converted some of the reactant mass to energy. Student 2: The chemical reaction produced a gas that escaped. Student 3: Some of the mass measurements were made with insufficient precision. Student 4: Heat released during the reaction caused the volume of the products to increase.Which students offered the most reasonable explanations?

If the hackings taught us anything in 2014, it's actually nothing. Password management firm SplashData released its list of the worst passwords of the year and it's just as terrible as you'd think. The most common leaked password in 2014 was "123456," followed by "password" -- both topped the list the year before, too. While numbers were as popular as ever as passwords, sports terms like "baseball" and "football" were used more often. Birthday years were common too (especially 1989, 1990, 1991 and 1992) and names like "Michael", "Jennifer" and "Hunter" are also among the top 100 worst passwords of 2014. Here's a look at the top 10 worst passwords of the year: 1. 123456 (Unchanged from 2013) 6. 234567890 (Unchanged) 2. password (Unchanged) 7. baseball (New) 3. 12345 (Up 17) 8. dragon (New) 4. 12345678 (Down 1) 9. football (New) 5. qwerty (Down 1) 10. monkey (New) This year's worst passwords are painfully weak, but what were once considered clever password strategies -- using symbols, capitalizations, the number 3 in place of the letter "e" -- are old tricks. It's now recommended to pick a different password for each account you use -- you wouldn't use the same key in all of your locks, and the same goes for passwords. Companies like Facebook, Twitter and Apple are now trying to make hacking more difficult on their services by offering two-factor authentication , which is basically like double locking your door at night. Each time you want to log into that account, the company will send a code to your phone -- it changes after each login attempt, so hackers would have to be in physical possession of your smartphone to know the code. To fight against hacking, some companies _ .

Children and teenagers who spend lots of time in front of screens-especially TVs-are easier to get more weight as they age .according to a new study. The findings agree with research suggesting all that inactive sitting and always watching advertisements may lead to poor eating habits. Researchers used results from a long-term study of children Who took surveys every other year. Children were between ages 9 and 16 when the study started. Out of 4,300 girls in the Study. 17 percent were overweight or obese .Twenty-four percent of the 3 .500 boys were also above a healthy weight The surveys included questions about their height and weight as well as how much time they spent watching TV and DVDs and playing computer and video games. From one survey to the next, each one-hour increase in children's daily TV watching was in connection with an increase of about 0.1 points on a body mass index(BMI) , which measures weight in connection with height. That's a difference of about half a pound per extra hour of TV. "The weight of the evidence is so strong that television watching is connected with unhealthy changes in weight among youth,"says Jennifer Falbe . Who led the study while at the Harvard School of Public Health in Boston. "It's important for parents to know all the obesity-causing screens that really should be limited in their children's lives, Falbe says. " When children watch TV. There are many food advertisements on TV that might lead them to eat a cookie or drink a soft drink. " What's mare .she says . " You can get into a hibernating state on the sofa. Even if children are sitting down while playing a computer game. for example. they might be a bit more active." According to Falbe , what should parents do to stop children getting fat?

It's easy to observe an athlete like Tiger Woods and feel like he's from another planet. He has won 14 major tournament titles and about $122 million in prize money and ads. He also has a happy family. It seems that he is too perfect to be one of us. But Woods has more in common with you than you might think. Woods' parents -- particularly his father -- set high expectations for him when he was a child. Before Earl Woods' death in 2006, he told Golf magazine, "My purpose in raising Tiger was not to raise a golfer. I wanted to raise a good person." By age two, Woods was already swinging a golf club. But once he entered school, Woods' father was careful to send the message that school work came first. Woods wasn't allowed to practice until his homework was done. When Woods finally reached the professional tour, his father continued to expect a lot of him. "Tiger will do more than any other man in history to change the course of human. The world is just getting a taste of his power," he said in 1996. Clearly, Earl Woods had great expectations of his son. In this way, Tiger Woods is actually like a lot of us. Many of us feel a similar pressure to make our parents proud. When this happens, it's easy to let that pressure overwhelm us. In a perfect world, we would all grow up to be Tiger Woods-like successes in our own fields. But that isn't possible. There are many things that we can't control in this life, despite our best efforts. There is, however, one thing that we can do: we can try to be a "good person", as Earl Woods asked his son to do. We can infer from the passage that _ .

What do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist may be able to put the tooth back in for you, but you have to get to the dentist first.In the meantime, you have to store the tooth so that it will stay healthy. The simplest thing to do is put the tooth back into your mouth, or you could put it in milk.Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth.He tried putting teeth into milk, into water, and into cell-culture medium .He also tried, just drying the teeth in the open air.He used teeth that had to be removed from people's mouths for various reasons.The teeth were put into one of the solutions or stored in the air for one hour.Then cells from the root of the teeth were scraped-off the teeth.Dr.Courts and the others then studied how healthy these cells were. The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth.However, few people keep cell-culture medium handy at home or in school. The next best thing was milk.But Dr.Courts said that the best thing of all was to wash the tooth and put it right back into its socket in the mouth.For some people, though, this is just too painful or upsetting.So milk will do, until you get your tooth (and your mouth)to a dentist. Milk can be used instead of cell-culture medium to put a knocked-out tooth in because .

Most teenagers in Britain receive pocket money from their parents. A report by the Bank of Scotland interviewed over 1,000 young people in Britain and found that 77% get pocket money. Different families give different amounts of pocket money. The average for eight-to-fifteen-year-olds in the UK is about PS6 a week. Children in Scotland receive slightly more than the national average and Londoners get the most. Teenagers, logically, get more money than younger children. Some fifteen-to-nineteen-year-olds receive more than PS100 a month. The report found that many children save at least a quarter of their weekly pocket money and that more boys than girls save their money. Lots of young people have to do housework to get their pocket money. They help at home with jobs like cleaning and cooking. A part-time job is a choice for teenagers who don't have pocket money or who want to earn extra money. About 15% of teenagers have a job. Popular part-time jobs for teenagers include delivering newspapers, shop work, and working in a restaurant or cafe. There are strict government laws about working hours. Only children over 13 can work (there are some exceptions, for example, for actors.) On a school day they can work a maximum of 2 hours a day but not during school hours. At weekends and during school holidays they can work longer hours. The national minimum wage for people aged 16-17 is PS3.57 per hour. 18-year-olds must earn a minimum of PS4.83. There isn't a national minimum waged for people under 16. In Britain some children and teenagers have a bank account. There is no legal age limit at which you can open a bank account but a bank manager can decide whether to allow a child or young person to open an account. Parents can put pocket money directly into their child's bank account and then children can use it to pay for things without carrying money. Saving or spending pocket money, working part-time and dealing with banks are all parts of the process of becoming a financially independent adult and having to earn and look after your own money. Which of the following is true according to the passage?

Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil , many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne . Fly on non-stop routes Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures. Choose larger aircraft. w.w.w.k.s.5.u.c.o.m Although small aircrafts have very good safety records, _ with more than 30 passenger seats are designed to comply with much stricter regulations and are tested more regularly to make sure they still comply. Also, in the unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival. Pay attention to the pre-flight safety briefing The information may seem repetitious , but it's worth listening to the flight attendants. And even if you've flown before, it doesn't mean you know everything about the aircraft you're on, such as the location of the closest emergency exit. Store things safely Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence . Keep our seat belt fastened while you are seated Cabin crew always tell you this, but it's important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. _ of flying is this: If you are told to do something, do it first and ask questions later. Let the flight attendant pour your hot drinks Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them. What is the overall reason for these air safety tips?

There are a lot of reasons why growing your own food is a good idea. GIY helps reduce carbon dioxide(CO2) emissions . Food in supermarkets travels a long way and that produces a lot of CO2. If you grow as many vegetables as you can at home, you can help save the earth. Vegetables you grow are also good for your health because they have more nutrients than supermarket vegetables and they don't have chemicals. How much money can you save? First of all, seeds are a lot of cheaper than vegetables, and secondly, you can save more by planting the most expensive and the most productive vegetables. You can give your vegetables to fiends and neighbors. It can make you very popular. Don't worry if you don't have much space. To GIY, you don't even need a garden. You can use pots on your balconies . And don't worry if your space doesn't get much sun. You can plant vegetables that don't need a lot of sun to grow. Grow your own vegetables now. You will have both a healthier body and a healthier social life. Where is the passage probably taken from?

We would probably all be amazed if we watched a videotape of ourselves performing basically unconscious acts as we go about the business of the day. These unconscious acts consist of all the little personal habits that we don't even think about, but definitely should. These are some of the things that present an image of who we are to others, and if we are careless in performing them, this image may well be other than we would like it to be. Parents who insist that their children practice good manners and habits at home are doing them a great service, for these habits then become lifelong and the natural way they do things. It proves true that their unconscious actions will reflect a well-mannered person. People who, for example, eat with both arms on the table at home will likely do so when out. Those who are lazy and slow in private will certainly be so in public. Children who are permitted to be disrespectful to their parents will follow suit with other adults, and will, most likely, become adults who are disrespectful of others. This is an area where the saying "practice makes perfect" may be applied. There is an article about the actress, Audrey Hepburn, known for her beautiful carriage and posture. According to her biographer, her grandmother tied her neck to the back of her chair, at table, so that she would not drop down suddenly over her food, but rather would learn to put only small amounts of food on her spoon or fork and bring them to her mouth. This is a rather extreme "at home" method for the development of erect posture, but it does illustrate the effectiveness of practicing good habits so that, when in public, they are instinctive. Those who eat with both arms on the table at home _ .

The Internet is full of headlines that grab your attention with buzzwords . But often when we click through, we find the content hardly delivers and it wastes our time. We close the page, feeling we've been cheated. These types of headlines are called "click bait". A headline on Busin,esslnsider.com reads: "This phrase will make you seem more polite". First, when you click through, you find another headline: "Four words to seem more polite." Then, on reading the article, you find it's actually an essay about sympathy. And what are the four words? They're "Wow, that sounds hard." On some video websites, you might encounter headlines such as "Here's what happens when six puppies visited a campus". Turns out it's just some uneventful dog footage . Nowadays, with the popularity of social media, many news outlets tweet click bait links to their stories. These tweets take advantage of the curiosity gap or attempt to draw the reader into a story using a question in the headline. These click bait headlines are so annoying that someone is attempting to save people time by exposing news outlet click bait through social media. The Twitter account @SavedYouAClick, run by Jake Beckman, is one such example. Beckman's method is to grab tweets linking to a story and retweet them with a click-saving comment. For example, CNET tweeted "So iOS 8 appears to be jailbreakable but...", with a link to its coverage of Apple's product announcements. Beckman retweeted it with this comment attached: "... it hasn't been jailbroken yet." Since founding the account, Beckman's Twitter experiment has brought him more than 131,000 followers. Beckman said that @SavedYouAClick is "just my way of trying to help the Internet be less temble." Asked about his goal, he said, "I'd love to see publishers think about the experience of their readers first. I think there's an enormous opportunity for publishers to provide readers with informative updates that include links so you can click through and read more. Beckman attached his comment to CNET's tweet to _

Many gardeners believe that "talking" to their plants helps them grow---it turns out that _ may not be crazy after all. According to the scientists from the University of Exeter, plants may keep communicating with each other through a secret "unseen" language. For their experiment, the scientists picked a cabbage plant that is known to send out a gas when its surface is cut. In order to get video evidence of the communication, they changed the cabbage gene by adding the protein---luciderase , which is what makes fireflies glow in the dark. When the changed cabbage plant was in full bloom, they cut a leaf off with a pair of scissors, and almost immediately, thanks to the luciderase, they could see the plant sending out "methyl jasmonate ". While this was a known fact, what was surprising was the fact that the minute this gas began to give out, the nearby cabbage plants seemed to sense some kind of danger and started to send out a gas that they normally have to keep predators like caterpillars away. What the scientists are not sure is whether the plants are trying to warn the other leaves or the near plants about the danger---something that will require further research However, the team, which is led by Professor Nick Smirnoff, is quite excited about the findings because this is the first time it has been proved that plants do not live a passive life, but actually move, sense and even communicate with each other. However, before you get all concerned, they are quite sure that plants do not feel the pain when they are cut, since they do not have nerves---so go ahead and bite into that juicy carrot! When the plant sent out methyl jasmonate, which of the following statements is NOT TRUE?

There is an old Chinese proverb that states "One Generation plants the trees; another gets the shade," and this is how it should be with mothers and daughters. The relationship between a mother and daughter is sometimes confusing. If close, the relationship can be similar to friendship. However, the mother and daughter relationship has unique characteristics that distinguish it from a friendship. These characteristics include a hierarchy of responsibility and unconditional love, which _ mothers and daughters from being best friends. Marina, 27 years old, says, "I love spending time with my mom, but I wouldn't consider her my best friend. Best friends don't pay for your wedding. Best friends don't remind you how they carried you in their body and gave you life! Best friends don't tell you how wise they are because they have been alive at least 20 years longer than you." This doesn't mean that the mother and daughter relationship can't be very close and satisfying. While some adult relationships are still troubled, many find them to be extremely rewarding. This generation of mothers and adult daughters has a lot in common which increases the likelihood of shared companionship. Mothers and daughters have always shared the common experience of being homemakers, responsible for maintaining and passing on family values and traditions. Today contemporary mothers and daughters also share the experience of the workforce and technology, which may bring them even closer together. Best friends may or may not continue to be best friends, but for better or worse, the mother and daughter relationship is permanent, even if for some unfortunate reason they aren't speaking. The mother and child relationship is closer than any other. There is not an equal relationship. Daughters should not feel responsible for their mother's emotional well-being. It isn't that they don't care deeply about their mothers. It's just that they shouldn't be burdened with their mother's well being. The mother and daughter relationship is a relationship that is not replaceable by any other. Mothers never stop being mothers, which includes frequently wanting to protect their daughters and often feeling responsible for their happiness. Mother always "trumps" friend. Why do many mothers and adult daughters keep a rewarding relationship?

London: It's well known that Charles Darwin's famous theory of evolution annoyed many people because it was against the Biblical view of creation. But few know that it also created problems for Darwin at home with his deeply religious wife, Emma. "Darwin _ the publication of On the Origin of Species to avoid offending his wife," says Ruth Padel, the naturalist's great - great - granddaughter. "Emma told him that he seemed to be putting God further and further off", Padel says in her north London home. "But they talked it through, and Emma once said, 'Don't change any of your ideas for fear of hurting me.'" As the world celebrates the 200th birthday of the man who changed scientific thought forever and the 150th anniversary of his book today, even his opponents admitted he was a giant figure. Though opposition to his theory continues, it is the elegant explanation of how species evolutes through natural selection that makes his 200th birthday such a major event. More than 300 celebrations have been planned in Britain alone, where Darwin's face graces the 10-pound bill along with that of Queen Elizabeth II. Shrewsbury, the central England town where Darwin was born and raised, is holding a month-long festival for its most famous son. Down House, his former home near London, will hold a permanent exhibition recreating some of his most famous experiments. Many more events have been planned all over the world. What would he be doing if he were alive today? Padel thinks he would properly be studying DNA and the immune system. It can be inferred that the passage is most probably _ .

As every computer owner knows, when their machines run a complex program they get pretty hot. In fact, cooling the processors can be expensive, especially when you're dealing with huge banks of computer servers. But what if that energy could heat private homes? A Dutch energy firm aims to do just that. Data centers of large Internet firms, such as Google, Apple, Microsoft and others, contain thousands of computer servers. As they process information they generate enormous amounts of heat requiring cooling towers that dissipate it into the atmosphere. A Dutch firm thinks paying for electricity to run the servers and then paying again to cool them is a waste of energy. Boaz Leupe, CEO of the start-up Nerdalize, says it's actually quite simple."We don't actually have to build the data center, which saves a lot of costs in infrastructure and we don't have the cooling overhead, plus that you have the environmental benefit, that the kilowatt hour you are using is used twice, once to heat the home and once to compute the clients task without the cooling overhead," says Leupe. The company developed what it calls an e-Radiator, a computer server that also works as an alternative heating source. Leupe says that five Dutch homeowners are experimentally using them in their homes. "We reimburse the electricity the server uses, and that we can do because of the computer clients on the other side, and, in that way, home owners actually get heating for free, and computer users don't have to pay for the overhead of the data center," says Leupe. One of the participants in the year-long experiment, Jan Visser, says the amount of heat produced by e-Radiator depends on the work being done by the server's processors so it cannot be used as the primary source. But he is ready to try it. "If it gives good enough warmth, you can use less of your existing central heating, and there is the chance for a home owner to pay less bills." Nerdalize says e-Radiators generate temperature of up to 55 degrees Celsius and could save up to $440 in annual heating costs. Which of the following can be the best title for the passage ?

Adding math talk to story time at home is a winning factor for children's math achievement, according to a new research from the University of Chicago. The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together. Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math. Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement. The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement. "Many Americans experience high levels of anxiety when they have to solve a math problem, with a majority of adults feeling at least some worries about math," said Beilock, professor in Psychology and author of Choke, a book about stress and performance. "These math-anxious parents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way." Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children's math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math. The more times parents and children in the math group used the app, the higher children's achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar students in the reading group by almost three months in math achievement at year's end. We can infer from the passage that _ .
|
[
"children using the app for three months can see gains in math achievement",
"children whose parents are uneasy about math outperform other students",
"it is the math problems related to the stories that make the great difference",
"the frequency of using the app has nothing to do with children's achievement"

Ask a group of elderly people what it was about their lives that made them happiest overall, and they'll probably mention some warm relationships with family and friends. If you're satisfied with your social life, according to psychologists, you tend to be satisfied with life in general. From the point of my 50s, I'd say that sounds about right. Some of my happiest moments are the ones I spend with my husband, a few close relatives, and a handful of very good friends who know me well and like me anyway. But the more I read about how social media are interfering with good old-fashioned friendship, creating virtual bonds that can't quite take the place of real ones, the more I wonder just how today's 20-somethings will look back on their own lives when they're my age. After all, much crucial relationship building work is done in the 20s. According to research by the late Bernice Neugarten of the University of Chicago, who helped launch the academic study of human development, people choose most of their adult relationships, both friends and lovers, between the ages of 22 and 28. The friends we make in our 20s are not only best friends forever; they're also our first truly chosen friends. And choosing how to commit to these friendships is an essential psychological task of the 20s. But with so much of friendship in this age group now being developed online, an essential question is what the effect of that interaction is. A study, conducted in 2010 by Craig Watkins and Erin Lee of the University of Texas at Austin, investigated the Facebook habits of 776 young people between the ages of 18 and 35. "Whether it is a wall post, a comment, or a photo," they wrote, "young people's engagement with Facebook is driven, primarily, by a desire to stay connected to and involved in the lives of friends who live close by, far away, or have just entered into their lives." This kind of constant contact can be efficient, but it can also be upsetting. For one thing, it adds a new layer of concern to a young person's already-heightened awareness of social ranking, giving appearance-conscious young people yet another thing to worry about. "I see other 20-somethings feeling pressured to constantly keep up a public image, especially a public image online," wrote Ariana Allensworth on the group blog. "Folks are always keeping the world informed one way or another about what they're up to, where they're at, what projects they're working on. It can be a bit much at times." Not the most fertile ground for real-world friendship. Which of the following is a disadvantage of making friends online?

"It makes people pay less attention to social ranking.",
"It robs people of the happy moments spent with friends.",
"It keeps people away from their family and close relatives.",
"It prevents people from keeping in contact with their friends."

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. " From the passage, we can infer that if you want to see the objects in the sky_.

Recently we told you about a finding that more years of school could help students get higherscores on intelligence tests.That was the finding of a study of teenage males in Norway.Now,other research shows that physical activity may help students do better in their classes . The research comes as educators in some countries are reducing time for activities like physical education.They are using the time instead for academic subjects like maths and reading.The studies appeared between 2007 and 2013.They included more than 55,000 children,aged 6 to 18. Amika Singh:"Based on the results of our study,we can conclude that being physically active is beneficial for academic performance. There are,first,Physiological explanations,like more blood flow, and so more oxygen to the brain.Being physically active means there are more hormones produced like endorphins .And endorphins make your stress level lower and your mood improved, which means you also perform better." Also,students involved in organized sports learn rules and how to follow them.This could improve their classroom behavior and help them keep their mind on their work. The study leaves some questions unanswered,however.Ms.Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement.This is because of differences among the studies . Also.they were mostly observational studies.An observational study is where researchers do not do controlled comparisons.They only describe what they observe.So they might observe a link that students who are more active often have better grades.But that does not necessarily mean being active was the cause of those higher grades. The researchers said they found only two high - quality studies.They called for more high- quality studies to confirm their findings.They also pointed out that " _ Still,the general finding was that physically active kids are more likely to do better in school.Ms.Singh says schools should consider that finding before they cut physical education programs.Her paper on "Physical Activity and Performance at School"is published in the Archives of Pediatric and Adolescent Medicine. What's the purpose of writing the passage?

It is 4 o'clock in the early morning. Everything but the computing room on the campus of the university appears as quiet and misty as the mysterious hell. In the computing room, 30 students with sleepy eyes, sit still at their desk, beating the dirty and worn keys. Staring at the colorful screen, they tap continuously for hours. For the other parts in the world, it might be in the middle of the night, nevertheless here time represents nothing. It is an entirely enclosed field. These young computer "hackers" are tracing a sort of stimulus , a drive so exciting and absorbing that it ignores nearly anything else in their lives and becomes the focus of their being. They are addicted computer programmers. Some of these students have been glued to the console for no less than twenty hours even with no break for meals or rest. Some have been sleeping on sofas and chairs in the computing room, trying to struggle for a few moments' rest but hating to get too far away from their addicted machines. It is not necessary for most of these students to be at the computing room in the middle of the night. What they are working belong to no assignments. They remain there because they desire to be -- they can not resist the attraction of the computers. Furthermore, they are in groups instead of being alone. There are hackers at computing rooms all over the country. In the unimaginable way, they focus on nothing but computer. They escape from schooling and live beyond friendship; they might have difficulty being employed, choosing to travel from one computing room to another. They may even give up personal health. "There is one hacker in my memory. We actually had to lift him away from his chair to feed him and arrange him to rest and sleep. We truly worried about his health," says a computing science professor at California University. Professors of computer science are nowadays paying more attention to this hacker phenomenon and are on the watch for future hackers and more and more severe computer addicts. They believe firmly that hackers are not simply resulted from the close relationship with a machine. It is the result of social relationship with the attractive thinking machines, which are becoming nearly universal. Which of the following is NOT true of those young computer "hackers"?

"For them, computer programming is the only purpose for their life.",

"In reading the lives of great men, I found that the first victory they won was over themselves... self-discipline with all of them came first." -- Harry S. Truman That is the quotation that had me thinking yesterday. Discipline , in particular self-discipline, is what will get us through most things in life, from writing this simple post to Achieving Greatness for You and I. You may ask, "Why is discipline important in writing this post?" For people who have tried writing, you would know how hard it might get sometimes to actually sit down and finish the whole article in one period without getting up every few minutes to get a drink, a snack or toilet break etc. Just with most things in life, often we lack the self-discipline to see us through what we are hoping to do or achieve. One area where self-discipline is clearly important is in losing weight. Some people are constantly looking for quick fix to their weight problem; they will jump at anything that is claimed to help them lose weight in the shortest time. They may lose weight fast, but they will find the result short-term especially if they do not change the way they live and the food they eat. A friend of mine shared his experience going through the journey from 115 kilograms to 56 kilograms in around one year. His journey of losing weight started from a trip with his daughter to the doctor for her check-up. He playfully weighed himself on the weighing machine while his daughter was having the check-up. The doctor saw his weight and made a remark, "If you maintain that balloon weight, you cannot see your grandchildren." That made him decide, "Enough is enough!" Not only that, he felt tired easily and his excessive weight made him feel like a walking balloon. In that moment of awakening, he made decisions to change his lifestyle and eating habits. The author's friend was determined to lose weight when he _ .

With only a click of the mouse, rumours can be forwarded between microblogs very quickly. As an example, recently, sensitive netizens discovered that some photos displayed on microblogs describing Beijing's June rainstorm had actually been Sina.com is one of the major Internet portals in China with hundreds and thousands of users, and a majority of celebrities and famous citizens have their microblog accounts on this portal. As recently as six months ago, the website decided to establish a specialized team to prove rumours and provide accurate information for its users. Tan Chao is in charge of the team. " Before I took the job, I usually couldn't identify what information was real and what was fake. But during the process of identification, we discovered that a lot of information was false, including fake photos, fake news stories and rumours that had been spread through microblogs." It's not just website portals which are taking on fact-checking responsibilities, but also a number of civic-minded netizens, who recently set up a Rumour Identification Federation on Sina.com's microblog system to help netizens identify fake information online. Dian Zizheng is the team leader of the federation. He says they've publicized more than 150 pieces which contradict rumours, which attracted more than 10 thousand visitors within two months. "We live in an age of new media, so we can't use the old methods to prove rumours. We can't wait for the media to prove the facts with related administrative departments and then release a formal announcement. We can't allow rumours to run wild and then deal with it, we need to fight rumours while they're spreading. I think that this is the best way to deal with rumours nowadays." Some experts say this displays the advantages of the internet compared to other traditional media. The open platform allows information to be examined and clarified by netizens. But experts like Ding Wengguo,President of the Journalism and Communication College at the China University of Political Science and Law says this self-correction function of the Internet is still quite limited. "It's still quite different to tell which information is true in such an open environment by just reading a number of different opinions on the same issue. This is something which we need to pay attention to. If society is flooded with too much false information, and it's allowed to spread in such a fast manner, then people will be suspicious of all kinds of information including important information from authorities. It also worsens problems relating to social communications and mutual-understanding, which in turn harms society as a whole." Experts suggest that the government should react more quickly in the Internet age. Once a rumour begins to spread, administrative departments should make announcements as early as possible to drive away rumours before they lead to bad outcomes. What is the best way to prove rumors on microblogs?

Q: I currently entered college in New York. Since English is not my first language, I sometimes ask a friend to read my essays to help fix the grammar and language. I believe I'm being graded mainly on my ideas, and my friend helps me get my ideas across better in English. Is this OK? -Mariana A: It's good that you want to succeed in your written work at college. Making use of available resources to help you succeed is a smart strategy . But while you may believe that your instructors don't care as much about how you write as they do about your ideas, that' s not a fair assumption. Certainly, your ideas are important. No matter how polished your writing is, it will not disguise a poorly expressed idea in a paper. But as a college student, being able to organize your thoughts clearly-whether you're speaking in class or writing a paper-is critical to show that you've mastered the material in each course. This does not mean you shouldn't ask others to review your written work before handing it in. That's OK. You should not, however, allow a friend or anyone else to rewrite parts of your papers for you. Instead, ask them to simply let you know about any parts of the paper that are unclear and need work. Many colleges have writing centers where tutors will work with you on your writing-without doing the work for you. Regardless of whether you consult with a friend or a tutor, the right thing is for you to talk to your instructors to ask their advice and let them know you plan to seek assistance with your writing. If you ask them in advance for guidance on what's appropriate and what's not for the written work they assign, that will allow you to be as transparent as possible about how you completed your _ -Professor Byron What problem does Mariana meet?

I was puzzled! Why was this old woman making such a fuss about an old copse which was of no use to anybody? She had written letters to the local paper, even to a national, protesting about a projected by-pass to her village, and, looking at a map, the route was nowhere near where she lived and it wasn't as if the area was attractive. I was more than puzzled, I was curious. The enquiry into the route of the new by-pass to the village was due to take place shortly, and I wanted to know what it was that motivated her. So it was that I found myself knocking on a cottage door, being received by Mary Smith and then being taken for a walk to the woods. "I've always loved this place," she said, "it has a lot of memories for me, and for others. We all used it. They called it 'Lovers lane'. It's not much of a lane, and it doesn't go anywhere important, but that's why we all came here. To be away from people, to be by ourselves. " she added. It was indeed pleasant that day and the songs of many birds could be heard. Squirrels watched from the branches, quite bold in their movements, obviously few people passed this way and they had nothing to fear. I could imagine the noise of vehicles passing through these peaceful woods when the by-pass was built, so _ but as I hold strong opinions about the needs of the community over-riding the opinions of private individuals, I said nothing. The village was quite a dangerous place because of the traffic especially for old people and children, their safety was more important to me than an old woman's strange ideas. "Take this tree," she said pausing after a short while. "To you it is just that, a tree. Not unlike many others here." She gently touched the bark, "Look here, under this branch, what can you see?" "It looks as if someone has done a bit of carving with a knife." I said after a cursory inspection. "Yes, that's what it is!" she said softly. She went on, "He had a penknife with a spike for getting stones from a horse's hoof, and I helped him to carve them. We were very much in love, but he was going away, and could not tell me what he was involved in the army. I had guessed of course. It was the last evening we ever spent together, because he went away the next day, back to his Unit." Mary Smith was quiet for a while, then she sobbed. "His mother showed me the telegram. 'Sergeant R Holmes ...Killed in action in the invasion of France.'..." "I had hoped that you and Robin would one day get married." she said, "He was my only child, and I would have loved to be a Granny, they would have been such lovely babies'- she was like that! " "Two years later she too was dead. 'Pneumonia , following a chill on the chest' was what the doctor said, but I think it was an old fashioned broken heart. A child would have helped both of us." There was a further pause. Mary Smith gently caressed the wounded tree, just as she would have caressed him. "And now they want to take our tree away from me." Another quiet sob, then she turned to me. "I was young and pretty then, I could have had anybody, I wasn't always the old woman you see here now. I had everything I wanted in life, a lovely man, health and a future to look forward to." She paused again and looked around. The breeze gently moved through the leaves with a sighing sound. "There were others, of course, but no one can match my Robin!" she said strongly. "And now I have nothing - except the memories this tree holds. If only I could get my hands on that awful man who writes in the paper about the value of the road they are going to build where we are standing now, I would tell him. Has he never loved, has he never lived, does he not know anything about memories? We were not the only ones, you know, I still meet some who came here as Robin and I did. Yes, I would tell him!" I turned away, sick at heart. Which of the following words can best describe Mary Smith?

There are all kinds of food in the world. Some people like the Chinese food. Firstly, the Chinese food has a lot of fruit and green vegetables. It has little sugar and fat. Secondly, the Chinese food is very delicious and has many dishes. So Chinese people can keep fit and have white teeth. However, some people enjoy the western food. Now many people, especially the workers in companies , are too busy to have lunch slowly so the western food meets their need and they can eat quickly. And the food is not too bad, too. It is a great pleasure to try eating a different style of food. In my opinion, I like the Chinese food more than the western food. First of all I'm a Chinese and used to Chinese food, it can keep us healthy. On the other hand, the western food is high in fat, sugar and salt. If you eat too much these food and don't take enough exercise, you'll get fat easily. The western food is too expensive and "not good value for money".

We know, painkillers in a tablet can make your headache go away, and antibiotic from a tube can prevent your cuts from becoming infected. Can medicine come in chicken eggs? A team of scientists from Scotland says "yes." They've kept some special chickens that lay eggs with disease-treating drugs inside. These drugs are made of molecules called proteins. Animals make thousands of proteins--they're the main ingredients in skin, hair, milk, and meat. Since animals can make proteins easily, they're good animals for making protein drugs. Researchers have already made cows, sheep, and goats that pump out protein drugs in their milk. But chickens are cheaper to take care of, need less room, and grow faster than these other animals. "Those qualities could make chickens a better choice to become living drug factories." says Simon Lillico of the Roslin Institute near Edinburgh, Scotland. Lillico and a team of researchers changed chickens' DNA--the code that tells cells how to make proteins--so that the birds' cells made two protein drugs. One drug can treat skin cancer, and the other treats a nerve disease called multiple sclerosis. The scientists changed the chickens' DNA so that the birds made these drugs only in their egg whites. This protects the chickens' bodies from the drugs' possible harmful effects and makes it easy for scientists to collect the drugs. These special chickens can pass on their drug-laying abilities to their chicks. So far, the Scottish researchers have kept five generations of drug-producing chickens. But the scientists need to improve these chickens. The chickens don't make enough drugs to treat people yet. Once the researchers perfect their technique, you might eventually take your medicine from chicken eggs. Which of the following is Not True according to the passage?

[
"It takes much shorter time for chickens to grow than cows, sheep and goats.",
"Compared to cows, sheep and goats, chickens are less expensive to be raised.",
"Chickens can produce the best quality of drugs among the drug-producing animals.",

Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years. European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month. _ Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004. A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex. "It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia. Just like bears and frogs, the hibernation of human beings would cause a person's metabolism to lower so they would need less energy. Medical research, however, is just half of a space flight hibernation system. There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor life functions and serve the physiological needs of the hibernator. According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045. What's the best title for the passage?

Will it matter if you don't take your breakfast? Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast. This fact appears to be especially true if a person works with his brains. If a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention in class. Contrary to (......) what many people believe, if you don't eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.

Lack of exercise is considered a risk factor for cancer. There is considerable evidence that inactivity is connected with increased risk for lung cancer, breast cancer, etc. In the Aerobics Center Longitudinal Study, more than 32,000 people (25,000 men and 7,000 women) were given a preventive medical examination that included a machine exercise test to measure physical fitness. They were given a physical fitness score, with one being the lowest and five being the highest fitness level. Then these people were followed for an average of 8 years. During this time, 179 men and 44 women died of cancer. Data from the Aerobics Center Longitudinal Study show people have lower rates of cancer with higher levels of physical fitness. Studies from the Cooper Institute for Aerobics Research in Dallas suggest that men with high fitness levels are less likely to die of cancer. The Aerobics Center Longitudinal Study also found that fitness level was more important than weight in predicting longevity . While results showed that fitness and normal weight are the ideal combination, researchers found that men who were fat but performed well in the machine performance had just a slightly increased all-cause death rate, including cancer, compared to the more slim men. The fat, but fit, men particularly lived longer than the slim, but flabby , men. These statistics called for a warning to the overweight: The first health goal for the overweight should be to become as fit as possible at their current weight. 67. The text mainly talks about _ .

A chip inserted in a young quadriplegic's brain is already improving his quality of life. Soon the benefits may be more widespread. A 25-year-old man unable to move from the neck down recently did what many assumed impossible. After a knife attack that had left him paralyzed, all he could move was his head, which he used to push a switch and call for a nurse. And he could turn his wheelchair by blowing into a straw near his face. That was it. Then last June, a Foxborough (Mass.) company called Cyber Kinetics opened the man's skull and inserted a special chip no larger than a baby aspirin. That insert has given him a few additional and precious abilities. When connected to a special computer via a cable, the chip translates the young man's thoughts into commands that let him move a cursor across a PC screen and open e-mail. He can draw a circle with a computer painting program. And he can use a robotic hook to perform simple tasks like picking up a candy and sliding it across a table. All he has to do is to think. Several new studies have begun or been completed in the past year. In fact, more than half of the scientific papers in this field, called brain-to-computer interaction (BCI), have been published in the past two years, notes Jonathan Wolpaw, a research physician at Wadsworth Center, the New York State Health Dept.'s research laboratory. Brain surgeries are no longer rare: Thousands of Parkinson's disease patients have had special devices inserted in their brains to ease uncontrollable shaking and other symptoms. The inserts themselves have improved, so the body doesn't reject them as furiously . And significant development has been achieved in software used to interpret the brain's signals and change them into commands understood by computers. But increased demand for thought technology remains the biggest reason for the field's progress. Today, 4 million Americans live with paralysis according to the Christopher Reeve Paralysis Foundation. Scientists hope that thought technology will reduce the impact of such disabilities. People with spinal-cord injuries, for example, often lose their ability to walk because the communications network between their brain and their legs has been interrupted. The brain still commands the leg muscles to move, but they don't hear its orders. Thought technology, scientists hope, will bridge this communications gap. "Our goal is for you to see paralyzed people eating at a restaurant and for you not to know that they are paralyzed," says John Donoghue, founder and chief scientific officer at Cyber Kinetics. What was the young man's trouble after a knife attack?

Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in factories of loud music or other common sound at home and at work. A person only needs to hear the noise for little more than one second to be affected. An American scientist has found that using aspirin increase the temporary hearing loss or damage from loud noise. He did an experiment using a number of students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about two times as great. The scientist said millions of persons in the U.S. use much larger amounts of aspirin than were used in his experiment. He said these persons face a serious danger of suffering hearing loss from loud noise. One conclusion you can draw from the passage is that aspirin _ .

Can dogs help with OCD? You might watch and laugh when your dog chases its tail because it looks cute. But did you know that, even though it might appear like a fun game, it could mean your pet is sick? Researchers have found that if a dog runs after its tail, chases cars and barks at flies that are not there, it may have obsessive compulsive disorder (OCD, ). In fact, OCD is even more common among humans. The symptoms are varied: some people check and recheck the locks before they go out; others are extremely afraid of germs and have to wash their hands many times a day. English soccer star David Beckham, for example, cannot stand odd numbers of items in his fridge. So if he has three cans of drink he will throw one out, according to his wife Victoria. Hoping to better understand OCD in humans, a team of scientists from the University of Helsinki, Finland, studied 368 dogs, including those that chase their tail for several hours daily or a few times a month, according to Sciencedaily.com. They also examined dogs that had never chased their tails. Scientists took the dogs' blood sample and asked their owners some questions about their pets' daily life. Findings showed that among all kinds of dogs, bull terriers and German shepherds were likely to chase their tails, which led scientists to believe that genes can cause OCD. Diet also plays a part. It was found that dogs that eat food with certain vitamins and minerals chased their tails less. "Interestingly, there are indications that vitamins and minerals are helpful in human OCD treatment," said researcher Katriina Tiira. Moreover, tail-chasing is often found among dogs that were separated from their mothers too early or ones that didn't receive enough care. They are also more likely to turn out to be shyer and more afraid of loud noises at a young age. The study can help us understand the causes of OCD in humans. "Dogs share the same environment with humans, and large animals are physiologically close to humans," said Hannes Lohi, leader of the study. According to the study, OCD _ .

"In the online world you don't need to fill buildings or lecture theatres with people and you don't need to be trapped into a lecture timetable," says Peter Scott, director of the Open University's Knowledge Media Institute. The Open University, the UK's open access university, which allows people to study from home in their own time, has been an international pioneer of degree courses online. The university, with more than 263,000 students in 23 countries, has become a record breaker on the iTunes U service, which provides a digital library of materials for university students and staff.Instead of music or movies, Apple's iTunes U provides a download service for lectures and resources from universities around the world.Top universities from the Massachusetts Institute of Technology and Harvard in the US to Oxford and Cambridge in the UK have been making their materials available, with no charge to the users. There have been 31 million downloads of OU materials, more than any other university, representing roughly 10% of all iTunes U downloads.Nearly 90% of these users are from outside the UK.In this online era, the OU student is also getting younger.A quarter of students are aged under-25 and only 10% are aged 50 or over.That change can only be accelerated as the cost of going to university increases in many countries.The prospect of learning from Harvard from your own bedroom is getting closer. "We have a belief that a degree and an opportunity are rights for all citizens.And we have got to enable the population of students attending higher education to scale up.What I am most excited about is that the privilege of going for higher education is not something only for the wealthy or for the smartest or for the most well-equipped students in the future," an American educator says.Online education will be a way of opening up more choices and getting beyond the big brand names of the most exclusive universities. At the Open University, Peter Scott says they are trying to develop services that give students exactly what they want, from face-to-face learning to the fully online experience."We can produce brilliant televisual material and get it to you on YouTube, on iTunes U or even on the web. According to the passage, online education has many advantages EXCEPT that _ .

Which is safer --- staying at home, traveling to work on public transport, or working at the office? Surprisingly, each of these carries the same risk, which is very low.However, what about flying compared to working in the chemical industry? Unfortunately, the former is 65 times riskier than the latter! In fact the accident rate of workers in the chemical industry is less than that of almost any of human activity, and almost as safe as staying at home. The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby.It is this that makes chemical accidents so newsworthy.Fortunately, they are extremely rare.The most famous ones happened at Texas City (1947), Flixborough (1974), Seveso (1976), Pemex (1984) and Bhopal (1984). Some of these are always in the minds of the people even though the loss of life was small.No one died at Seveso, and only 28 workers at Flixborough.The worst accident of all was Bhopal, where up to 3,000 were killed.The Texas City explosion of fertilizer killed 552.The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives, just a month before the unfortunate event at Bhopal. Some experts have discussed these accidents and used each accident to illustrate a particular danger.Thus the Texas City was caused by tons of ammonium nitrate, which is safe unless stored in a great quantity.The Flixborough fireball was the fault of management, which took risks to keep production going during essential repairs.The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep.When the poisonous gas drifted over the town , local leaders were incapable of taking effective action.The Pemex fire was made worse by an overloaded site in an overcrowded suburb.The fire set off a chain reaction of exploding storage tanks.Yet, by a miracle, the two largest tanks did not explode.Had these caught fire, then 3,000 strong rescue team and fire fighters would all have died. From the passage we know that "ammonium nitrate" is a kind of _ .

Entire populations of American toads breed within the same few days at the same time each year, usually late April or early May. The toads hop to their breeding ponds after the ground has warmed and the first hard spring rain falls. To get there, many of the toads will cross roads that cut through their habitat. It will be a grand view of hopping toads as well as a disastrous killing by cars! The toads are "slow in moving at that time of year--it's still cool, they've been inactive--and they get killed" by cars when crossing roads, said Serrao, a naturalist. An April night five years ago, when Serrao went out to a country road to watch the moving of the toads, he counted 100 toads; 95 were hit by cars. A similar story can be told for several other species of toads, frogs, crocodiles and turtles around the world. The world's amphibians are reducing, and road-killing is just one factor behind it. Other better-known causes of the decline include global warming, insecticides , and the loss of wetlands. Serrao says unless these animals get help crossing the road, their local populations will disappear. Jackson, a biologist, said one way to help amphibians survive road crossings is to construct "amphibian tunnels" beneath the road. Jackson says tunnels should be a 0.6-meter-by-0.6-meter box, open at the top, and fitted with an iron grate to allow enough air and light into the tunnel. In addition, fences or walls should extend out from either side of a tunnel for about 30 meters, which guide amphibians toward the tunnels. European countries have built amphibian tunnels for decades. Jackson led a team that installed the first such tunnel in prefix = st1 /Americain 1987, which helped over 3/4 of the local amphibian population safely cross the road. Jackson says that there are about a hundred amphibian tunnels in the UStoday, but many of them were not carefully designed and probably not working well because land developers wanted to save money. When do American toads hop to breeding ponds?

At times my mom has been uncomfortable seeing these qualities in me. For example,when I was 12,I went to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about it. She kept telling me how things were different in Puerto Rico,to always put on sunscreen,not to wander away from my grandmother,and other warnings. She helped me pack and did not leave the airport until she saw my plane take off. But despite her worries,she let me go on my own. As I moved into my teens,she continued to give me space to grow and learn,even when it might have been difficult for her. When I reached my senior year,I decided to move away for college. Once again I found that I differed from my peers:While many of them wanted to stay close to home,I couldn't wait to be out in the world on my own. While my mom may not have been happy at the thought of my going away,she was supportive and excited for me. One big thing I realized during my senior year,as my mom granted me more freedom,was that she actually believes in me and trusts me. That means a lot. Most of my life,and especially when I was little,the main person I tried to impress in my schoolwork or other things was my mother. I knew she expected nothing but the best from me. Sometimes it was hard to live up to her standards;getting a single B on my report card would make me feel bad because I knew she wanted me to have all A's. I know that her high standards have helped me stay focused on what's important,like education,and made me who I am. I am thankful for her support and involvement in my life .Most of all I respect her. She is the strongest woman I know and that's why I have turned out so strong and independent.

It is obvious that doctors recognize obesity as a health problem. So why is it so hard for them to talk to their patients about it? The results of two surveys, one of primary care physicians and the other of patients, found that while most doctors want to help patients lose weight and think it is their responsibility to do so, they often don't know what to say. "So while doctors may tell patients they are overweight, the conversation often ends there," said Christine C. Ferguson, director of the _ . "Patients are not told about the possibility of diabetes ," she said. "And doctors don't feel they have good information to give. They felt that they didn't have adequate tools to address this problem. The lack of dialogue hurts patients, too. The patient survey, of over 1,000 adults, found that most overweight patients don't even know that they're too heavy. Only 39 percent of overweight people surveyed had ever been told by a health care provider that they were overweight. Of those who were told they were obese, 90 percent were also told by their doctors to lose weight, the survey found. In fact most have tried to lose weight and may have been successful in the past--and many are still trying, the survey found. And many understand that losing even a small amount of weight can have a positive impact on their health and reduce their risk of obesityrelated diseases like hypertension and diabetes. Dr. William Bestermann Jr., medical director of Holston Medical Group, in Kingsport, Tenn. , which ranks the 10th in obesity among metropolitan areas in the United States, said the dialogue had to be an ongoing one and could not be dropped after just one mention of the problem. "If you're to be successful with helping your patients lose weight, you have to talk to them at actually every visit about their progress, and find something to encourage them and coach them," he said. He acknowledged that many doctors tend to be not optimistic. "Part of this is that there's this common belief, and doctors are burdened by it, too, that overweight people are weak-willed and just don't have any willpower and are selfindulgent and all that business," he said. "If you think that way, you're not going to spend time having a productive conversation." How many of the patients surveyed have been advised by their doctors to lose weight?

Jim Dunbar has been late for work, holidays, meals with friends, left women waiting on first dates and even had to sneak into funerals long after they've begun. The 57-year-old said that his poor timekeeping is down to a medical condition that he was diagnosed with at an appointment at Ninewells Hospital in Dundee, which he was 20 minutes late for. It is thought that the condition is caused by the same part of the brain affected by those who suffer from Attention-Deficit Hyperactivity Disorder (ADHD), and means Mr Dunbar cannot properly judge how long things take to complete. "I blamed it on myself and thought.Why can't I be on time? I lost a lot of jobs.I can understand people's reaction and why they don't believe me," said Mr Dunbar. Mr Dunbar recently tried to go to the cinema and knowing it could be a problem getting there for a 7 pm showing, he gave himself an 11-hour head start.But he still managed to arrive 20 minutes late. He has a special clock in his living room to make sure that the time it displays is always exactly right, but it doesn't help.He has tried wearing a watch, setting his clocks fast but still hasn't found a solution. "I've been late for funerals and slipped in and hid at the back of the hall.I arranged to pick my friend up at midday to go on holiday and was four hours late.He was angry because we had booked a ferry and everything.A friend invited me for a meal and I was more than three hours late.It has affected my entire life." But some experts are skeptical about Mr Dunbar's diagnosis. "The condition isn't in the DSM5 (the American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders) so I'm not sure you can really call it a condition," said Dr Sheri Jacobson."Repeated lateness is usually a symptom of a condition such as ADHD or depression but it can also just be habit.I think making everyday human behaviour into a medical condition is unwise." Why was Mr Dunbar late for the cinema showing?

Her father told her, "If you do, I know how to deal with it, so let's start running!" That's just what they did every day. It was a wonderful experience for them to share. And there were no seizures at all while she was running. After a few weeks, she told her father, "Daddy, I want to break the world's long-distance running record for women." So she did. That year, she wore a T-shirt that read, "I love epileptics" and completed her run to San Francisco. Her dad ran every mile at her side, and her mom, a nurse, followed in a car behind them in case anything went wrong. In her second year in college, Patti's classmates got behind her. They built a huge poster that read, "Run, Patti, Run!" Her foot was injured when she was running to Portland. A doctor told her she had to stop her run. "Doctor, you don't understand," she said, "This isn't a whim of mine. I'm doing it to let people know -- we can do what others do. Isn't there a way I can keep running?" "Yes, but it would be unbelievably painful." The doctor said. But she told the doctor she could do it. At last she finished the run to Portland and completed her last mile with the governor of Oregon. What would be the best title for the text?

The teaching of physics in schools is in danger of dying out unless urgent action is taken to deal with a serious lack of teachers, the government is warned today. The number of students taking physics at A-level has fallen 38% since 1990, according to a research. At the same time the number of mew physics teachers has dropped sharply while the shortage is likely to worsen as older teachers retire. prefix = st1 /Britain's leading scientists and engineers expressed alarm over the findings, which they say are part of the problems in science education generally. Lord May of Oxford, president of the Royal Society, theUK's National Academy of Science, said, "The problems facing science at A-level are well beyond physics. We have over and over again noted the general downward trend of students studying the sciences beside biology and math at A-level. If we fail to deal with this then we may lose the ability to train the next generation of scientists, technologists and engineers." Alan Smithers and Pamela Robinson, who did the research in 432 schools and colleges inEnglandandWales, said that since 1990, the number of physics students had fallen by 38%, from 45,334 to 28,119. Nearly 10% of state schools now do not offer A-level physics, and of those that do 39.5% had five students or fewer taking it this year. Over the same period, the research discovered, the number of people who are allowed to become physics teachers dropped from about a third of the science total to 12.8%. The supply of physics teachers is not _ itself, with nearly twice as many aged over 50 as 30 or younger. Another danger is the redefinition of science subjects to "general science". Professor Smithers and Dr Robinson warn that the subject is in danger of dying out in schools." Physics in schools and colleges is at risk through redefinition and lack of teachers with expertise in the subject," they said. "If physics is to survive in schools, both as basic education and as a platform for higher level study and research, there is a need for immediate action." From what Lord May of Oxford said, we can learn that _ .

Where are you from?" She waved a hand in front of my face. "China," I said as I shook her hand unhappily. Kelly kept talking to me. She was very thoughtful. When we were served drinks and meals, she made sure that I had enough room in my seat. "I don't want to make you uncomfortable with my elephant size!" she said sincerely. I couldn't help but let down my guard. As we talked, I was surprised by her wise words. She had read many books and was very smart. I asked her if she ever thought about losing some weight. "Aren't you worried about the diseases that come with being overweight?" "Not at all. I eat healthy and walk regularly," she said.

Stephen Hawking was born in Oxford, England, on January 8, 1942. At the age of 17, he entered University College, Oxford. He wanted to study mathematics, but took up the study of physics when math was unavailable. He received a Ph.D. in physics despite being diagnosed with Ameliotrophic Lateral Sclerosis while at Oxford in 1963. In 1985 he became ill with pneumonia , and since then has required 24-hour nursing. Dr. Hawking's determination, along with the help of his family and associates, has allowed him to continue to work. In 1970 he began studying black holes. His research led him to predict that black holes send out radiation in the X-ray to gamma-ray range of the spectrum . In the 1980s he returned to an earlier interest, the origins of the universe. He has co-authored many publications, such as 300 Years of Gravity and The Large Scale Structure of Space time. Dr. Hawking has also written books such as A Brief History of Time, Black Holes and Baby Universes and other Essays, The Universe in a Nutshell and others. He continues to give lectures, despite having been unable to speak since 1985, with the aid of a speech synthesizer and a portable computer. He currently holds Isaac Newton's chair as the Lucasian Professor of Mathematics at Cambridge University in England. Before Hawking started researching black holes, _ .

A company has just launched what it calls "the world's first free standardized English test" recently. Anyone can take the test for free. The new exam is called the EFSET, which is short for Education First Standardized English Test. The company, Education First, is known by the letters EF. It is estimated that there are two billion English language learners worldwide. Many of them are interested in attending an American college or university. To do so, foreign students need to take the Test of English as a Foreign Language -- better known as TOEFL. However, many foreigners are not wealthy enough to take the TOEFL. In addition, test-takers often have to travel overnight to reach an official testing site. The World Bank says an average Cambodian worker earns only about $1,000 per year. Approximately the cost of taking the TOEFL is 17.5 percent of the average worker's yearly wage. It is not just individuals who find the test pricey. Some governments also find it prohibitive. What's more, not everyone needs official results from the TOEFL or IELTS -- the International English Language Testing System. In the future, it's likely that the government may use the EFSET to test millions of employees and students. Experts believe that the EFSET meets the highest value in language testing. It uses special computer software that makes the questions easier or harder, depending on one's performance. The EFSET measures all the English learners' levels while the IELTS and TOEFL only measure learners' levels from moderate to advanced. The EFSET is unique in the sense that it gives free online access to anyone interested in measuring their English level. There is a 50-minute and a two-hour version of the test, which its developers are calling the EFSET Plus. Both versions test only reading and listening skills. It's hopeful that speaking and writing skills will be tested in the future. The IELTS and the TOEFL still use humans to rate the speaking and writing sections. It's a huge deal for students who are in areas where they can't get to the TOEFL or the IELTS. However, it is too early to know whether the EFSET results are acceptable for colleges and universities in America. Why do many foreign students take the TOEFL?

There's no danger of 88-year-old Harry Ward forgetting his wife Doris's Valentine's Day card - the couple still use the same one he bought her 70 years ago. When 17-year-old Harry Ward presented Doris with a Valentine's Day card as he boarded a train to join the wartime effort on February 14, 1941, he must have been fairly confident about his affections . After all the couple had been dating since they met in a cafe three months earlier. But little can he have imagined that 70 years on, not only would he still be happy about having married Doris, but that every year she would present him with the very same card he gave her that Valentine's Day. "I bring it out of the cupboard and put it on our mantelpiece every Valentine's Day," she said. "It's a special to me now as it was 70 years ago. Harry has never bought me one since, because I have this one every year." They first met in a cafe. "Harry was in the cafe drinking and he said hello. He asked me my name and we got talking happily. He offered to walk me to the bus stop but when we got outside, a bombing raid had started and we had to run to a nearby air-raid shelter ," Doris said. Mr. Ward said,"I knew Doris was the one for me the moment I met her. I gave her the Valentine's card then and she is still my Valentine now." Mrs. Ward's card is not the only thing that has endured the passing of time. "Harry is quite romantic and we are as still in love as the day he first gave me this card,"Dorris said.

Many Chinese people who have been to the United States think that Americans pay a little part of their money for food each day. Yet, in the latest 13 years, food prices have gone up 30% for most American families. Everyone agrees that _ . But who is really responsible ? Many people say the farmers who produce the vegetables, fruit, meat, and eggs are responsible. But farmers say that the rise in food prices is very small compared to (...) the rise in their cost of living. Farmers think middlemen have got much more money than they do. Middlemen are those people who stand between the farmers and the people who buy and eat the food. For example, truck drivers, owners of food stores and so on. Are middlemen really responsible for higher food prices? Economists don't think so. They have found that the money that meat packers and food stores get is less than 1% in all. They say that food costs more now because modern housewives have jobs outside the home. They have less time for cooking after a day's work. They like to buy food which has already been prepared before it reaches the market. They want to buy many kinds of food that can be put on their dining tables easily and quickly. But of course they must be prepared to pay for the services of those who make their work easier. It seems that the answer to the question of rising prices is not an easy one. Quite a number of people share the responsibility for the sharp rise in food costs. Which of the following is a middleman?
