Most people looking for ways to quit smoking worry about weight gain, and with good reason. Smokers who quit tend to pack on an average of 5 pounds after they stop smoking cigarettes. A new study, published by the journal Science, explains why this happens. The new research explains that nicotine appears to combine with appetite-regulating neurons in the brain, besides the receptors that bring about addiction. These neurons help regulate how much food gets consumed, but under the influence of nicotine, they lose their self-control. This is why when smokers quit, they tend to eat more and gain weight. The researchers believe that their discovery will lead to the development of drugs that aim at nicotine receptors on brain cells that control appetite. In the future, weight gain may no longer be a reason for smokers to delay the decision to kick the habit, but that's no reason to wait. Nicotine-replacement treatment, while not for everyone, can help. Here are a few more ways to quit smoking and stay slim. Drink water. To improve metabolic rates, make half of those glasses ice water. Juice can be too high in calories, something you'll want to keep an eye on your journey toward being a slimmer non-smoker. Plan your snacks. Healthy snacks help keep your metabolism working, so you continue to burn calories while stopping wild hunger pain, or fake hunger. Keep moving. Exercise kills two birds with one stone. It helps you burn calories and prevents you from eating when you're not truly hungry. It's also a feel-good stress reliever . Focus on your fitness and how being healthy makes you feel. Make exercise a goal and think of quitting as your reward for being physically fit. The author believes that _ .

For many years, I had a belief that my suffering was due to my size. I believed that when the weight disappeared, it would take old wounds, hurts, and rejections with it. Many weight-conscious people also mistakenly believe that changing our bodies will fix _ . Perhaps our worst mistake is believing that being thin equals being loved,being special, and being cherished. We fantasize about what it will be like when we reach the long-awaited goal. We work very hard to realize this dream. Then, at last, we find ourselves there. But we often gain back what we have lost. Even so, we continue to believe that next time it will be different. Next time, we will keep it off. Next time, being thin will finally fulfill its promise of everlasting happiness, self-worth, and, of course, love. It took me a long while to realize that there was something more for me to learn about beauty. Beauty standards vary with culture. In Samoa a woman is not considered attractive unless she weighs more than 200 pounds. More importantly, if it's happiness that we want, why not put our energy there rather than on the size of our body? Why not look inside? Many of us strive hard to change our body, but in vain. We have to find a way to live comfortably inside our body and make friends with and cherish ourselves. When we change our attitudes toward ourselves, the whole world changes. The passage tries to highlight the importance of _ .

Most people think zoos are safe for animals, where struggles such as difficulty in finding food and avoiding natural enemies don't exist. Without such problems, animals in zoos should live to an old age. But that may not be true for the largest land animals on earth. Scientists have known that elephants in zoos often suffer from poor health. They develop diseases and behaviour changes. Sometimes, they even become infertile, or unable to have babies. To learn more about how elephants are affected, a team of international scientists compared the life spans of elephants born in zoos with those living outdoors in their native lands. Zoos keep detailed records of all the animals, such as birth dates, illnesses, weight and death. These records made it possible for the researchers to analyse 40 years of data on 800 African and Asian elephants in zoos across Europe. The team found that female African elephants born in zoos lived an average of 16.9 years while those in the wild lived an average of 56 years. Scientists don't yet know why wild elephants seem to be so much better than their zooraised elephants. Georgia Mason, a biologist who led the study, thinks stress and obesity may be to blame. Zoo elephants don't get the same kind of exercise they would in the wild, and most are fat. Another finding from the study showed that Asian elephants born in zoos were more likely to die early than Asian elephants caught in the wild and brought to zoos. Mason suggests stress in the mothers in zoos might cause them to have babies that are less likely to survive. In order to let the elephants in the zoos live longer, people should _ .

If music makes you smarter, and exercise helps brain function, can exercising to music really boost brainpower? Some researchers said it could. Volunteers who listened to Vivaldi~ "Four Seasons" while working out on a treadmill did much better on a test of verbal ability than when they exercised without music, a team at prefix = st1 /OhioStateUniversityfound. "Evidence suggests that exercise improves the cognitive performance of people with coronary artery disease ," said psychologist Charles Emery, who led the study. "And listening to music is thought to enhance brainpower. We wanted to put the _ together," Emery added in a statement. Writing in the latest issue of the journal Heart & Lung, Emery and colleagues said they studied 33 men and women taking part in a cardiac rehabilitation program after having bypass surgery, angioplasty or other procedures to treat clogged arteries. The volunteers said they felt better emotionally and mentally after working out with or without the music. But their improvement on the verbal fluency test doubled after listening to music on the treadmills ."Exercise seems to cause positive changes in the nervous system, and these changes may have a direct effect on cognitive ability," Emery said. "Listening to music may influence cognitive function through different pathways in the brain. The combination of music and exercise may stimulate and increase cognitive arousal while helping to organize cognitive output." Emery said he now wanted to test people using music of their own choice. "We used The Four Seasons' because of its moderate tempo and positive effects on medical patients in previous research," Emery said. "But given the range of music preferences among patients, it's especially important to evaluate the influence of other types of music on cognitive outcomes." If we can combine music and exercise, we can _

After lots of hype, the new iPhone 3GS has arrived, boasting an improved camera, better battery life, and speedier performance. But is it a must? The iPhone 3GS is available in two versions: 16GB and 32GB. The 16GB version costs $199, while the 32GB version costs $299. From the outside, the iPhone 3GS looks exactly like the iPhone 3G. Like the iPhone 3G, the new model comes in black and white versions, and sports a 3.5-inch touch screen. Most of the changes to the iPhone 3GS have been made on the inside. Apple says that battery life is better, but the biggest boost is in the iPhone's speed: The iPhone 3GS runs twice as fast as the iPhone 3G. Instead of a lot of software installed on it, the iPhone 3GS comes with the most recent version of the iPhone Software --version 3.0- installed, but it does come with easy access to Apple's App Store. The speedier performance of the iPhone 3GS extends to surfing the Web, too. You can see entire Web pages, and can zoom in and out with ease. The notable new messaging feature on the iPhone 3GS is support for MMS. You can send pictures and videos by SMS, rather than having to send them via e-mail. Other new and very-handy e-mail features include the ability to search through your e-mail messages and contacts, as well as the option to use a landscape-oriented keyboard when composing messages. The camera has been upgraded from 2 megapixels to 3 megapxiels, and adds auto-focus. If you already own an iPhone 3G, the iPhone 3GS may not be worth the additional cost, since you can get many of its cool features for free with the iPhone 3.0 software upgrade. But if you've been using an older iPhone or smart phone, or are new to the smart phone world, the iPhone 3GS will amaze you with its speed and plentiful features. What does MMS probably refer to in the passage?

Running like the wind, roaring like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China. This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund. The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950s, there were over 4,000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species. Sixty-six of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves. "Breeding has damaged the quality of the species," said Pei Enle, deputy director of the Shanghai Zoo. To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts and can hunt wild animals by themselves at the African base. "South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in," said Lu Jun, office director of the National Wildlife Research and Development Centre. "We tried in Fujian Province, but it was not successful as there was not a complete eco-chain and there was a lack of space." The tigers should return to China in 2009 when the reservations in Fujian are ready. How is the programme of sending several tigers to South Africa getting on?

Pollution is anything that harms or disturbs the natural environment. Just as chemicals in a river or litter in the park are pollution, so unwanted noise can pollute too. Some people cause noise pollution by playing their radios too loud, but the main problems in many areas are aircraft and traffic noise. In science, a noise is a mixture of vibrations without any smooth, regular pattern, for example, the sound of an electric drill or a radio tuning from one station to another. Noise can be reduced by soundproofing. You have probably noticed the difference between the sound in a empty room and a furnished one. Some materials are very effective at _ sounds. They are often made up of fibres or foam, because these trap layers or bubbles of air. Sounds do not travel well through air. Most of the curtains, carpets and upholstery in your home are good sound absorbers and will stop sound travelling through windows, walls and floors. A lot of noise pollution can be avoided if a machine is designed properly. Modern cars contain different materials to reduce the amount of noise coming from the engine and other moving parts, as well as noise produced by the car as it moves through the air. Have a look around next time you are in a car. What soundproofing can you see? By replacing metal parts in cars and other machines with parts made of plastics and foams, there is now far less noise than there used to be. According to the passage, what will most probably cause noises?

Many children think mobile phones are cool. They come in fun colors and let you talk with friends anytime and anywhere. In the U.S., more than 90 million people use mobile phones. Many of these people are children. For children, mobile phones are more than phone calls. They are fashionable. Most mobile phone users don't think about the health problems caused by mobile phones. Some scientists say that mobile phones give off radiation that might be bad for the users. One newest study shows that mobile phone radiation might raise a person's chance of getting some kinds of cancer . Other scientists say mobile phones don't' threaten people's health. They say that they have not found any link between phone use and cancer. Scientists say that people can protect themselves from mobile phone radiation. One way is to use a headset .

"An apple a day keeps the doctor away" is one of the most common sayings in the English languages. This is because apples were one of the first foods that medical professionals recognized as healthy---their benefits became obvious when, quite simply, doctors found that people who ate apples were sick less often than those who did not. Today we have a more specific understanding of why apples are so beneficial to overall health. Apples can help keep your levels of bad cholesterol down. The pectin in apples helps you to maintain cardiovascular health and reduce LDL cholesterol(which is the "bad" kind). Apples themselves do not add cholesterol to your diet and are full of water and fiber to help weaken the cholesterol in other foods you might digest. According to Health Diaries, people who eat two apples per day may lower their cholesterol by as much as 16 percent. Apples are naturally low in calories and high in water content. Eating an apple can satisfy your hunger and keep you from reaching for high-sugar, high-calories snacks. By eating apples, you will be more able to maintain a healthy weight because they fill you up, potentially stopping you from eating food that encourages a waistline increase. Apples contain considerable levels of boron , which helps build healthy bones, and can also prevent diseases like arthritis. Apples are rich in vitamin C, which is known to help build immunity. Studies have shown that apples can decrease the risk of breast cancer and liver cancer. One theory is that the apple skins are responsible for this, so be sure not to take apple skins off before you eat them, as you could remove some of the health benefits. What's the main idea of the passage?

The federal school lunch program for 30 million low-income children was created more than half a century ago to combat malnutrition . A breakfast program was added during the 1960s, and both attempted to improve the nutritional value of food served at school. More must be done to fight the childhood obesity epidemic, which has caused a frightening peak in weight-related disorders like diabetes, high-blood pressure and heart disease among young people. The place to start is schools, where junk food sold outside the federal meals program--through snack bars and vending machines--has pretty much canceled out the benefits of all those efforts. Federal rules that govern the sales of these harmful foods at school are limited and have not been updated for nearly 40 years. Until new regulations are written, children who are served healthy meals in the school cafeteria will continue to buy candy drinks and high sodium snacks elsewhere in school. Many states' school districts have taken positive steps, but others are likely to resist, especially districts that sell junk food to finance athletic program extracurricular activities, and even copier expenses. Those districts should take note of a study released in 2009 in West Virginia showing that the budgetary costs of switching from sodas to healthy drinks such as fruit juice, milk, and water were very little. Even if the switch costs money, so be it. The school should not be trading their students' health to buy office supplies. Over the last five decades, the obesity rates for adolescents have tripled. Unless there is decisive action, weight and inactivity-related disorders will bother a steady larger proportion of the work force and replace smoking as the leading cause of premature death. The tone of this passage is _ .

Some colors people see late at night could cause signs of clinical depression . That was the finding of a study that builds on earlier study findings. They show that individuals who live or work in low levels of light overnight can develop clinical depression. Doctors use the word "clinical depression" to describe severe form of depression. Signs may include loss of interest or pleasure in most activities, low energy levels and thoughts of death or suicide. In the new study, American investigators designed an experiment that exposed hamsters to different colors. The researchers chose hamsters because they are nocturnal, which means they sleep during the day and are active at night. The animals were separated into four groups. One group of hamsters was kept in the dark during their night-time period. Another group was placed in front of a blue light, a third group slept in front of a white light, while a fourth was put in front of a red light. After four weeks, the researchers noted how much sugary water the hamsters drank. They found that the most depressed animals drank the least amount of water. Randy Nelson heads the Department of Neuroscience at Ohio State University. He says animals that slept in blue and white light appeared to be the most depressed. "What we saw is that these animals didn't show any sleep uneasiness at all but they did mess up biological clock genes and they did show depressive sign while if they were in the dim red light, they did not." Randy Nelson notes that photosensitive cells in the eyes have little to do with eyesight. He says these cells send signals to the area of the brain that controls what has been called the natural sleep-wake cycle. He says there's a lot of blue in white light. This explains why the blue light and white light hamsters appear to be more depressed than the hamsters seeing red light or darkness. _ tends to cause hamsters to be depressed.

First aid is emergency care for a victim of sudden illness or injury until more skillful medical treatment is available. It may save a life or improve certain vital signs including pulse, temperature, a clear airway, and breathing. In minor emergencies, first aid may prevent a victim's condition from turning worse and provide relief from pain. First aid must be done as quickly as possible. In the case of the seriously injured, a few minutes can make the difference between complete recovery and loss of life. First-aid measures depend upon a victim's needs and the provider's level of knowledge and skill. Knowing what not to do in an emergency is as important as knowing what to do. Improperly moving a person with a neck injury, for example, can lead to permanent spinal injury and paralysis . Despite the variety of injuries possible, several principles of first aid apply to all emergencies. The first step is to call for professional medical help. The victim, if conscious, should be reassured that medical aid has been requested, and asked for permission to provide any first aid. Next, assess the scene, asking other people or the injured person's family or friends about details of the injury or illness, any care that may have already been given, and pre-existing conditions such as diabetes or heart trouble. The victim should be checked for a medical card that describes special medical conditions. Unless the accident scene becomes unsafe or the victim may suffer further injury, do not move the victim. First aid requires rapid assessment of victims to determine whether life-threatening conditions exist. One method for evaluating a victim's condition is known by the acronym ABC, which stands for: A---Airway: is it open and clear? B---Breathing: is the person breathing? Look, listen, and feel for breathing. C---Circulation: is there a pulse? Is the person bleeding extremely? Check skin color and temperature for additional indications of circulation problems. In administering first aid to a victim, you should first of all _ .

China's Ministry of Culture has recommended 10 cyber games that are suitable for minors to play as part of its drive to purify the on-line environment for the young. The 10 cyber games were selected by the ministry's on-line games censorship committee from scores of games recommended by the Chinese public.l The games are all domestic products. They include five role playing games (RPG), four recreation and chess games, and one educational game, such as "Warring States II Online," "Rainbow Island Online," and "Wonderlands of learning and games." These games have made their way into the final recommendation list because they are considered "healthy" and can "enhance intelligence," according to the ministry. The ministry hoped the list could serve a a guidance for parents to better direct their children in the winter vacation, which usually lasts nearly two months from January to February each year. This was the third time for the ministry to publish recommended cyber games list. The previous two were made public respectively in January 2006 and August 2005 with a total of 25 games inlisted. In the past few years, on- line games have become the favorite pastime of young people. However, it is argued that such social problems as game addiction, juvenile delinquency and perversion among minors by on-line violence and pornography have come from an inadequately regulated Internet. About 9.72 percent of Chinese netizens between the ages of 13 and 30 suffer Internet addiction, said a report issued last month by the China Youth Association for Network Development (CYAND). According to the China Internet Network Information Center (CINIC), the main Internet watchdog, China had 210million Internet users at the end of 2007 and its online population is on course to become the world's largest at the beginning of this year. Net users between 18 and 30 accounted for 49.9percent of the total users. Although the CINIC did not give the figure of those below 18, teenagers and youths have obviously taken up more than half of the total number of net users. And the number of users under age 18 increased rapidly last year, the CINIC noted. What can be inferred from the passage?

The home computer industry has been growing rapidly in the United States in the last ten years. Computers used to be large, expensive machines that were very difficult to use. But scientists and technicians have been making them smaller and cheaper while at the same time they have been made easier to use. As a result, their popularity has been increasing as more people have been buying computers for their homes and businesses. Computers have been designed to store information and compute problems that are difficult for human beings to work out. Some have voices that speak to their operators. Stores use computers to keep records of their inventories and to send bills to their customers. Offices use computers to copy letters, record business and keep in touch with other offices. People also use computers in their homes to keep track of the money they spend. One important new use of computers is for entertainment. Many new games have been designed to be played on computers. People of all ages play these games. People also buy home computers to watch movies and listen to concerts at home. They have become very popular indeed. Home computers can be used for _ .

Ceaseless technology. A punishing workweek. That to -do list that keeps multiplying. It is no wonder many of us find it difficult to have a sufficient amount of sleep. But will sleeping more on the weekend make up for hours of lost snoozing ? One sleep expert, W. Christopher Winter raised the question. Sleeping binge Getting eight hours of shut-eye each night is generally recommended, but many people don't. As the week rolls from Monday to Friday, they accumulate a sleep debt. Spending a few extra hours in bed on a Saturday morning, people assume, will help them " catch up" on lost sleep. They're likely right, " Nobody knows how long the horizon is, probably a few nights, but studies show that recovery sleep in the short term does work," says Dr. Winter, a member of the American Academy of Sleep Medicine. Sleep banking Recent data suggests that banking sleep in advance of a long night can actually offset upcoming sleep deprivation . If you knew you were going to have to stay up all night on a particular day, for example, you could sleep for 10 hours a day for multiple days before the event, and be fine, Dr. Winter says. Just plan ahead. Routine naps A scheduled nap is healthier than catching up on or banking sleep. " Because sleep extension can make you feel groggy , I always recommend a short nap [if a person feels they need it ], at the same time, every day," says Dr. Winter. He adds that 25 minutes is ideal. " When you schedule a short nap, your body anticipates it and slows down, without falling into a deep dream sleep," he says. That refreshing, scheduled break is better than an occasional weekend lie-in. " The body likes routine," he says, " When it's prepared, it works more efficiently."

Advice to "sleep on it" could be well founded, scientists say. After a good night's sleep a problem that couldn't be solved the night before can often appear more manageable. Researchers at the University of Luebek in Germany have designed an experiment that shows a good night's sleep can improve insight and problem-solving ability. "If you have some newly-got memories in your brain, sleep acts on these memories and restructures them, so that after sleep the insight increases," said Dr Jan Born, a neuroscientist, at the University. To test the discovery, they taught volunteers two simple rules to help them turn a string of numbers into a new order. There was also a third, hidden rule, which could help them increase their speed in solving the problem. The researchers divided the volunteers into two groups: half were allowed to sleep after the training while the rest were forced to stay awake. Dr Jan Born and his team noticed that the group that had slept after the training were twice as likely to figure out the third rule as the other group. "Sleep helped," Born said in a telephone interview . The important thing is that you have to have a memory description of the problem you want to solve in your brain and then you sleep, so it can act on the problem." But Born admitted that he and his team don't know how restructuring of memories occurs or what controls it. Pierre Maquet and Perrine Ruby of the University of Liege in Belgium said the experimental evidence supports the suggestion that sleep can help develop creative thinking. Although the role of sleep in human creativity will still be a mystery, the research gives people good reasons to fully respect their periods of sleep, they added. How did Jan Born and his team carry out the experiement ?

A rabbit was hopping around, following all the smells he could smell. He had a great nose, smelling carrots, bushes, flowers, and other animals. He smelled melons and he smelled a dish of ice cream. Rabbits don't like ice cream, so he moved to the flowers faster. And he didn't really like to snack on melons either. He saw friends, the duckling and the mother duck, but he was moving too fast to get to the flowers. He could smell the flowers from a long way away. He kept hopping to reach them, faster and faster. One hop, two hops, three hops. On his third hop he always bounced a little higher. He finally smelled the flowers close, so he hopped a little bit faster. The flowers were in sight. He went up to them and smelled longer and harder than ever before. A wonderful smell at last. How many hops until the rabbit bounced higher?

Education plays a very important role in everybody's life. We go to school because we want to know more about the world around us. The typical classroom used to be the place where teachers and students were working and exploring the wonderful world of knowledge together, but now everything has changed. The Internet is one of those approaches. Learning via the Internet is a new style that seems to become successful than the traditional teaching. The Internet provides schools with a large amount of learning material that is accessible to students online. Owing to the choices of courses online, completing a program becomes much easier. We used to go to the library when we needed information and spend hours searching for the right sources. Today there is a "library" in our house and it is available 24 hours a day. From my personal experience, being a first time mother, I find that using information online is very helpful. While I am at home with my baby, I can still search for the material I need and exchange thoughts and information with my classmates without leaving my house. The Internet is not only a big information provider but also a money and time saver. People predict that education will be much cheaper in the future because of Internet access to information. The cost of land, building and wages for teachers are continuously increasing. In addition, regular courses (offline) depend heavily on books and other paper-based materials, while online education posts lectures, and assignments electronically, which saves thousands of dollars every year. With no physical restrictions, the Internet classes and courses are also very convenient. In classroom-based education there is a limitation on the number of students while Internet education is available to everyone. Students don't have to struggle in order to register for classes they like. Students will have more choices to take their courses and classes online. The Internet offers a wonderful opportunity to obtain knowledge in a more convenient and less expensive way. In my opinion, online life in the future is simply inescapable. Which of the following statements is NOT true?

"The Internet offers schools abundant learning materials.",
"Online learning changes the traditional learning way.",

Drinking a lot of water does not do any good to the body, according to two experts in the United States. In fact, they warn, drinking too much water could be, in certain cases, harmful. In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pensylvania, the United States, have denied the popular belief that drinking a lot of water clears body toxins better, improves skin, and helps reduce weight. Dr Goldfarb and Dr Negoianu say that they found little proof to back the public opinion that drinking 8 glasses of water every day benefits health. At the same time, they fond little proof of harm in drinking 8 glasses of water every day. It is widely believed that in some cases-such as athletes, people who live in hot, dry environments, and those with certain medical conditions-drinking a lot of water indeed helps, but no studies have been done to prove the benefits of this practice in average, healthy people, the website medheadlines.com reports. The study at the University of Pennsylvania also examined reports that some people experienced increased headaches when their consumption of water was low. In one small study, which the doctors reviewed, the group drinking the most water reported fewer headaches than the control group, "but the difference in the number of headaches was o small between the two groups as to be considered unimportant." The researchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glasses of water each each day. The website medheadines.com says that, according to an Indian doctor, drinking too much water is harmful. If water enters the body more quickly than it can be removed, problems can occur. According to the passage, we know that _ .

Can you speak to dolphins? Of course you can but you won't be able to understand them! We interviewed a biologist and asked her what research on dolphin communication has shown. This is what she told us. Just like dogs, cats and other mammals, dolphins communicate by using sound, vision , touch and taste. Each dolphin has its own signature whistle to identify itself and to call others. Dolphins don't have the ability to smell, but their hearing and eyesight are excellent. We also asked Jane if dolphins have got their own language. She told us that they have and that dolphins started talking to each other from birth. They make different sounds, including whistles, squeaks and click. Sometimes they even sound like a heavy metal band! We then asked Jane if any interesting experiments have been done. She told us that a very interesting experiment had been done with a mother dolphin and her two-year-old baby in an aquarium. They talked to each other over the telephone! The two dolphins were in separate tanks which were connected by a special under water system. Unfortunately the biologists couldn't understand what the dolphins were talking about because they haven't been able to decode dolphin language yet. However, it was very clear that the dolphins knew what they were talking about. Finally we asked Jane if there was hope that we would be able to understand dolphins in the near future. She told us that she and her team have been listening to dolphins for more than 17 years, using special equipment to record and analyze their language. Unfortunately they haven't been able to decode it yet, but who knows -- maybe one day we'll get a phone call from a dolphin. The word "analyze" in the reading mean _ .

Most American students have to say goodbye to fancy fruits these days. In school restaurants across the country, cheaper fruits like apples and oranges have taken their place. "People are afraid to spend now." said Linda Morrow, who owns a shoe and handbag store. "They don't know what the future will bring". During the financial crisis , several of the country's biggest banks have been forced to sell or close. This has made lots of Americans afraid to buy expensive things. The crisis began last year. Experts think it was because US banks lend money too easily. Last year a lot of people and companies, who borrowed money, found themselves unable to pay it back. This left the banks, as well as the people who put their money in the banks, without money. Since the banks borrowed money between themselves and even across borders , the whole world was in trouble. This month the US government agreed on a $700 billion plan to try to save the financial market. But no one is sure whether it will help or not. Last week presidents from 20 countries promised to work together to find a way out of the money trouble. Why are people in the US afraid to spend?

For most of history scientists and mankind in general considered plants to be passive organisms just with no reason or means of communicating with one another. But new research has revealed that many plants actually 'chat' quite a bit over their own networks, which may also indicate that your auntisn't quite as crazy as you thought. You know, the one that talks to her petunias and expects an answer. In fact, many plants form internal communication networks and are able to exchange information efficiently. These connections enable the plants to share information via internal channels in a manner very similar to computer networks. So what kind of things do plants tell each other? Researcher Josef Stuefer found that one purpose for plants having their own "chat systems" is to warn each other. He and his colleagues were the first to prove that clover plants do indeed warn each other via these network links if enemies are nearby. For example, if one of the plants is attacked by caterpillars , it will warn the other members of the network via an internal signal. After receiving a warning, the other plants will strengthen their protective chemical and mechanical resistance so that they are less attractive to advancing caterpillars. This early warning system allows the plants to stay one step ahead of their enemies. Experimental research has revealed that this communication significantly limits the damage to the plants. It is also known that plants have "family values", with new research revealing they have the ability to recognize close s in order to help each other survive. Research found plants from the same species of beach-dwelling wildflowers, for example, grew aggressively alongside unrelated neighbors but were less competitive when they shared soil with their siblings. Some researchers think that plants must communicate through their roots, identifying themselves using tiny chemical signatures specific to each plant's family. The research shows that our current concept of plants is probably a poor reflection of reality. Scientists are eager to discover in what ways, and to what extent, plants communicate with each other. The best title for this passage may be _ .

The coyote , that clever animal of wide-open spaces, has come to the nation's capital. In fact, coyotes have spread to every corner of the United States, changing their behaviors to fit new environments and causing researchers to deal with a troublesome new kind of creature: the city coyote. The coyote originally lived in the middle of the continent. One of its most obvious characters is its smartness, which has made the animal a notorious pest. Hunters trapped, shot and poisoned more than a million coyotes in the 1900s. It's still one of America's most hunted animals. Yet the coyote has survived. How has the coyote shown this extraordinary ability? "I guess if you wanted to use one word, it'd be ' _ '," says Eric Gese, an expert at Utah State University. Coyotes can live alone, in pairs, or in large packs like wolves; hunt at night or during the day; occupy a small region or an area up to 40 square miles; and live on all sorts of food, from lizards and shoes, to ants and melons. Unbelievably people helped coyotes increase when they killed most of the wolves in the United States. The spreading of coyotes into city areas, though, is recent. They travel at night, crossing sidewalks and bridges, running along roads and ducking into culverts and underpasses. No one knows why coyotes are moving into cities, but experts explain that cleverer, more human-tolerant coyotes are teaching urban survival skills to new generations. Occasionally, coyotes might attack human beings. There have been about 160 attacks on people in recent years. Therefore, people have been consistently told not to feed coyotes or leave pet food unsecured. That, plus a large trapping program in the neighborhood, has cut down on the coyote population. According to the passage, to cut down on the coyote population, people are advised to _ .

"A rolling stone gathers no moss ," but there is one living animal that does gather moss -- the three-toed sloth of South America. This slowest-moving member of the animal kingdom is so inactive that moss actually gathers on its body and turns it green -- strange as it seems! Most of the sloth's life is spent motionless, hanging upside down from a limb . And that is the way its hair grows. Long and coarse, the strands from receptacles for the damp jungle algae turn the brown fur a mossy green. Actually this moss helps the animal survive because it serves as a perfect camouflage against the leafy trees and hides the sloth from the jungle's swift-moving hunters. The sloth would have little chance of survival on the ground. With long, curved claws hooded over the limb of a leafy tree, it spends the long hot hours during the day drowsing and eating. Inch by inch, it strips the leafy limbs bare and crawls slowly down the trunk to find a new dining spot, but only at night. In addition to looking rather like a vegetable, the sloth is a strict vegetarian. Running out of its favorite leaf is about the only thing that will make a sloth move. Then its appetite may even force the animal into swimming a stream to reach a succulent . It will also force it into fighting to keep the tree all to itself. The sloth is lazy and prefers to be alone, but it will tolerate its own s! A suitable title for this passage might be _ .

Eating different colored foods can keep you healthy, as well as change your mood and behavior. Here is a list of colors, which can change your life. Blue/Purple Blue is considered to be peaceful and calming and it has the same effect on our health. The blue / purple color in food is due primarily to their anthocyanins which are antioxidants that are particularly heart healthy and may help support healthy blood pressure. Out of all the blue and purple foods available, blueberries are considered to have the highest antioxidant level. An analysis of the latest data from the National Health and Nutrition Examination Study found that people who eat purple and blue fruits and vegetables are at a reduced risk for high blood pressure and are less likely to be overweight. A food and health expert says that blue and purple color foods can prevent blood mass formation, and they also lower the risk of cancer. Foods that contain blue and purple colors are: reddish eggplant (especially the skin), blueberries, blackberries, purple grapes, etc. Green We all know that we should eat green as green symbolizes nature. The green foods are rich in isothiocyanates, which help resist cancer. Dr. Ashok Agarwal, a food and nutrition specialist, explains, "They are excellent sources of folic acid, vitamin K, as well as carotene . Diets high in those above are associated with lowered blood pressure." Foods that contain the green color are: broccoli, cabbage, cucumbers, etc. Red Lycopene in reddish fruits and vegetables is a powerful antioxidant that has been associated with a reduced risk of some cancers, and also provides protection against heart attacks. Dr. Smiths says, "Cooked tomato sauces are associated with greater health benefits as compared with the uncooked version as the heating process allows lycopene to be more easily absorbed by the body. Obtaining the most benefit from food depends on proper selection, storage and cooking of the produce." Foods that contain red color are: Tomatoes and tomato products, watermelon, guava, red onions, red chili, red apples, red grapes, cherries, etc. Orange The orange foods are also rich in carotene, which are particularly good antioxidants. These foods are commonly considered eyesight foods because they contain vitamin A. "Orange fruits and vegetables also play a part in preventing cancer, particularly of the lungs and stomach. Foods that contain the color orange are: Carrots, mangoes, sweet potatoes, pumpkins, etc. The passage tries to tell us that _ .

Experiments aboard the spaceship Columbia have disproved a theory on the human nervous system which won an Austrian professor a Nobel prize 79 years ago. West German astronaut Ulf Merbold disproved the theory during tests aboard the spaceship yesterday. His discovery is connected with the workings of the inner ear, the body's balance mechanism . In l914 Professor Robert Barany won the Nobel prize for Physiology and Medicine when he announced that temperature differences affected the inner ear and caused the eyes to blink . His theory was accepted by scientists. But Merbold carried out tests to find if the theory was correct and shocked himself and space officials when he proved it wrong. According to Barany's theory the eyes would blink when cold air was blown into one ear and hot air blown into the other. But if this theory was correct such a movement would be impossible in zero gravity . Both Merbold's eyes continually blinked when the test was carried out.

Shanghai Children Prove Money Smarts Shanghai,the financial center of China,sure has raised some money-savvy children. Ninety-two percent of Shanghai primary school students who took a recent test of their money smarts showed an understanding of financial management,and some even knew a thing or two about stocks and debts. The FQ,or Financial Quotient test was conducted on Monday at three primary schools.It was designed to measure the students'ability to handle money,their understanding of spending and saving,and their knowledge of family finances and investment . One 8-year-old could identify six ways to make money-including investing in the stock and real estate markets,selling old toys and getting good grades,said Xu Ting,head of the FQ Lab at Ant Fortune,the mobile financing platform of Alibaba Group Holding. The students scored 73percent on average,surpassing the organizer's expectations about what children might be expected to understand about money management,Xu said.Twenty-six percent of the 200test takers,who were aged 8to 11,scored over 80points,and only 8percent notched under 60. Asked about managing a New Year's money gift,61percent of the students said they would deposit the money in the bank,while 31percent said they would give it to their parents for investment.One student said he would lend the money to s to buy property-and charge interest. Not all of the students who were tested had received financial education,although it is studied at the primary school affiliated with the University of Shanghai for Science and Technology.Money education there is made into classes to teach students responsibility,teacher Xue Lei said. "It's mostly to help the students to manage their pocket money,"Xue said. Lao Kaisheng,a professor of education at Capital Normal University,shrugged off the test as more commercial than scientific.But it's clear that modern parents are conscious of money management and want their children to spend-and save-wisely.

A man enters a store to buy milk. He walks out of the store with milk. That is all-- milk. At the same time, a woman enters the same grocery store also to buy milk. She buys it. But, she also buys chicken and lemons to make dinner that night. Then she remembers to buy food for her son to eat at school. She also gets a bottle of wine for drinks with friends and a birthday card for her husband's niece. Then she gets coffee for breakfast, ice cream for dessert and remembers stamps to mail the bills. And don't forget soap for the bathroom. And that is the difference between the female and male brains simply explained in a grocery store. Generally speaking,men do one thing at a time. Women do many. Doing many things at one time is often called "multi-tasking", a very popular word these days. Now scientific research supports this theory about male and female brains. A recent study has confirmed what we have known all along--men and women think differently. Scientist at the university of Pennsylvania studied brain images of 949 people aged from 8 to 22 years old. They found that male brains have more connections on one side of the brain, or hemisphere. In female brain, they found more activity and connections between the right and left sides of the brain. The left side of the brain is known as the side of "reason" The right hemisphere is known as the "creative" side. Regina Verma is a professor at the University of Pennsylvania. She co-wrote the report. She says when women are asked to do something difficult they might use different parts of the brain. Men, she adds, generally use just one side of the brain. As a result, men generally deal directly with a problem. There is a strong connection between the "understanding" and the "action" parts of their brains. Women, however, might include other parts of the brain, like the part connected with reason and the part connected with sensitivity when solving a problem. Women take a less direct path to find a solution. Dr. Venma warns that the study should not lead anyone to expect some behaviors from women and others from men. By describing the scene of shopping, the writer wants to _ .

If you travel to a new exhibition at the San Francisco Conservatory of Flowers, you will have chances to see some meat-eating plants. Take bladderworts, a kind of such plant, for example. They appear so small and grow in a quiet pond. "But these are the fastest known killers of the plant kingdom, able to capture a small insect in 1/50 of a second using a trap door!" Once the trap door closes on the victim, the enzymes similar to those in the human stomach slowly digest the insert. When dinner is over, the plant opens the trap door and is ready to trap again. Meat-eating plants grow mostly in wet areas with soil that doesn't offer much food nutrition. In such conditions, these amazing plants have developed insect traps to get their nutritional needs over thousands of years. North America has more such plants than any other continents. Generally speaking, the traps may have attractive appearance to fool the eye, like pitcher plants, which get their name because they look like beautiful pitchers full of nectar . Hair-like growths along the pitcher walls ensure that nothing can escape, and the digestive enzymes can get to work. A tiny insect can be digested in a few hours, but a fly takes a couple of days. Some of these pitchers are large enough to hold 7.5 liters. Meat-eating plants only eat people in science fiction movies, but sometimes a bird or other small animals will discover that a pitcher plant isn't a good place to get a drink. If the trap door of a meat-eating plant is closed, the plant is

Smart phones that react to your moods and televisions that can tell it's you who's watching are in your future as Intel Corporation's top technology expert sets his sights on context-aware computing. Chief technology officer Justin Rattner showed how personal devices will one day offer advice. "How can we change the relationship so we think of these devices not as devices but as assistants or even companions?" he asked. Handheld devices could combine already common geographic location technology with data from microphones, cameras, heart and body monitors and even brain scans to offer their owners advice that today only a friend or relative could give. "Imagine a device that uses a variety of sensors to determine what you are doing at an instant, from being asleep in your bed to being out for a run with a friend, " Rattner said, "Future devices will constantly learn about who you are, how you live, work and play.'' Rattner also demonstrated a television remote control that figures out who is holding it based on how it is held, and then learns the viewer's entertainment preferences. As the world leader for decades in microchips for servers and desktop computers, Intel is hurrying to catch up in the profitable market for smart phones like Apple's iPhone and Research in Motion's Blackberry. Telephones with e-mail, global positioning and media players are pointing the way to a future where ever more functions are packed into ever smaller mobile devices. The smart phone industry, including technology giants like LG and Samsung, is likely to sell 270 million phones this year and grow 25 percent in 2011, according to market research company IDC. "I think you can expect to see features that support context-aware computing starting to appear in Intel products in the near future," Rattner said. But analysts say Intel faces an uphill battle getting its microchips into new phones as Nvidia, Marvell and Qualcomm have already made headway with cheap, lower-power processors based on designs by ARM Holdings. Rattner recognized that questions about privacy and people's willingness to be intimate with their computers will have to be settled before the future generation of smart phones he described takes off. "If you think identity threat is a problem today, imagine when your whole context is readily available on the Net.", he said. Which of the following are smart phones according to the passage?

Have you ever heard a news reporter talk about DNA?Reporters talk about DNA found at the scene of a crime.They talk about police finding DNA "fingerprints".Police sometimes use DNA as a clue to find out who committed the crime. DNA is a substance that makes up genes.Everything alive has genes.Plants have genes.Animals have genes.You have genes. Genes are the basic units of heredity .Heredity means all the characteristics you inherit from your parents.You get your genes from your parents.You inherit half of your genes from your mother.You inherit half of your genes from your father. Genes are a kind of code.A tree's genes tell what shape its leaves will be.A cat's genes tell what color its fur will be.Your genes tell what color your eyes will be.Your genes tell what color your hair will be.Everything about you comes from the code in your genes. Genes line up on strands called chromosomes in cells.Everything alive is made up of cells.Chromosomes are in the center,or nucleus of cells. Different parts of you are made of different kinds of cells.Your muscles are made of muscle cells.Your skin is made of skin cells.The code in your genes tells your body to make different kinds of cells.The genes in each cell tell the cell how to work.They tell the cell when to make new copies of itself. An Austrian monk named Gregor Mendel first saw inherited patterns in pea plants.He experimented with pea plants in the 1860s.One of the things,or traits Mendel studied was what makes some pea plants tall and some short.He said that the traits must come from units of heredity passed from the parent plants.These units were later called genes. In the mid-1900s,scientists discovered that genes are made of DNA.In the 1970s,scientists learned how to change DNA with genetic engineering.Scientists also learned that problems with certain genes cause diseases.Muscular dystrophy,cystic fibrosis,and hemophilia are some genetic diseases--diseases caused by problems in genes.Today,scientists are looking for ways to cure genetic diseases by changing genes through a process called gene therapy.

People are busy working every day, so they do not have enough time to do exercise. As a result, many people become too fat or too thin. To keep our bodies healthy, we have to do exercise every day. There are many kinds of exercises. Bending and stretching helps us move easily. Before we play ball games or swim, it is better for us to do bending and stretching exercises first. This kind of exercise is something called warm-up exercise. Running is also a good exercise. If we cannot run fast, we can jog. Jogging means running slowly Again, before we run or jog, we must do warm-up exercise. Also, we should not run or jog in busy streets. The air there is often dirty. Some people like weight lifting because it can make their bodies strong. Also, we need to do warm-up exercise before weight lifting. From the passage, we know _ .

"Congratulations, Mr. Jones, it's a girl." Fatherhood is going to have a different meaning and bring forth a different answer from every man who hears these words. Some feel proud when they receive the news, while others worry, wondering whether they will be good fathers. Although there are some men who like children and may have had considerable experience with them, others do not particularly care for children and spend little time with them. Many fathers and mothers have been planning and looking forward to children for some time. For other couples, pregnancy was an accident that both husband and wife have accepted willingly or unwillingly. Whatever the reaction to the birth of a child, it is obvious that the change from the role of husband to that of father is a difficult task. Yet, unfortunately, few attempts have been made to educate fathers in this re-socialization process. Although many good books have been written about American mothers, only recently have some books discussed the role of a father. It is argued by some writers that the transition to the father's role, although difficult, is not nearly as great as the transition the wife must make to the mother's role. The mother's role seems to require a complete transformation of daily routine and adaptation to a new life, on the other hand, the father's role is less demanding and immediate. However, even though we have mentioned the fact that growing numbers of women are working outside the home, the father is still thought by many as the breadwinner in the household. It is stated in the passage that _ .

Al Ossinger,an experienced mountain guide,knew it was time to leave Longs Peak in Colorado's Rocky Mountain National Park,and get off'quickly.The sky had turned threatening dark,and his ice ax at times gave out upset sounds.Suddenly,as Ossinger was crossing a large mass of rock,both hands pressed against it for balance,there was a roar,a flash of light and an electric current charged through his arms. "In that second. I thought 1 was finished,"he said,"Then I realized 1 was still there--the jolt hadn't knocked me off.My body and legs were all right,but my arms were paralyzed from the shoulder down.''Fortunately Ossinger was able to continue down and soon the feeling began to return to his shoulders,upper arms,and,two hours later,his fingertips.Ossinger was a lucky man. A single stroke of lightning,which is usually three to four miles long,travels at speeds of up to 100,000 miles per second.In a single flash,it can carry 100 million volts of electricity and reach a temperature of 55,000 degrees Fahrenheit,five times hotter than the surface of the sun.During its brief life span,lightning carries enough energy to power a 100-watt light bulb for as long as three months.If you find yourself unlucky enough to be near lightning's path,you could suffer a direct hit,sending electrical current though your body for some 5 00 milli-seconds.Because of the short duration,severe burns aren't common and the resulting burns are usually superficial . According to the national Weather Service,more people have been killed by lightning in the United States during the past 30 years,an average of 87 a year-than by either tornadoes or hurricanes,484 people were injured in 1994 alone.These"swords from the sky" are also responsible for an estimated$100 million to$300 million of property damage a year.During the 1980s an average of 5502 wildfires a year were sparked by lightning on national forest lands alone. Earth is struck by at 1east 100 of these flashes every second-more than 8.6 million strikes a day.For all its destructive power,lightning has its good sides too.It's likely that humans discovered fire from some early lightning-sparked flames.And all that activity above the earth may help create ozone ,which protects us from the sun's harmful rays.Lightning dancing across a summer night sky is a force to be respected and appreciated-from a distance. Electrical lightning is called"swords from the sky"to mean _ .

I grew up with a fat dad--450 pounds at his heaviest.Every week he would try a new diet,and my family ended up eating whatever strange food he was trying at that moment. After my thirdgrade year,my dad landed a lifechanging job in Manhattan.My mom,my little sister and I had to move away from our hometown,Chicago,and leave my grandmother and her beautiful food behind. Leaving my grandmother was far more frightening than the move to New York City.There would be no more special weekends at my grandmother's house,the only place I can remember feeling happy,safe and nourished .It was what I desired.In this new city,I felt extremely alone and lost,and I missed my grandmother terribly. My grandmother knew just how I felt--And she knew the _ .Every week,she would send me a card with a $20 bill,a recipe and a list of what to buy at the market.It kept us bonded,and her recipes filled my body and soul. Over the years,I have grown to better understand my father's struggles with weight and the toll it took on him and those who love him.I have come to realize he was driven not by vanity or selfishness as much as by a deep pain.And in spite of growing up in such an unhealthy eating environment (or perhaps because of it),as an adult I found a passion and a career as a nutrition consultant. Today,my father weighs 220 pounds and is a vegan .How he got there is a story I hope to share in the coming weeks.More importantly,food is no longer a barrier that keeps us apart,but a bridge that keep us connected.There is nothing my dad enjoys more than talking with me about dietary theories and his weightloss victories.And now I am the one regularly sending recipe cards to my father's house,just as my grandmother did for me.

If you have ever experienced jet lag ,you know how much of a drag it can be. Jet lag happens as a result of air travel, when traveling between two or more time zones. Your body is used to operating in a certain time zone, and when its timing is affected, you're likely to have problems. Edward Norton's character in the movies Fight Club faces the struggle of jet-lag-induced sleeplessness due to his constant traveling. Sleeplessness is just one of the effects of jet lag, and it can lead to other problems, such as tiredness, memory loss and confusion. That's not something you should have to fight on a business trip and it certainly won't make your vacation very enjoyable, either. Sleeplessness is the biggest problem for travelers that suffer from jet lag. Don't worry. You can do something to prevent it. Modify Your Body Clock To prevent the effects on your body's timing that come with crossing time zones, you need to change your body clock sooner, rather than later. You can do this by putting yourself on the same time as your destination time zone before you fly. If you know that you will be traveling to London from the eastern United States, you'll have a five-hour time difference to deal with. Plan for it. Avoid Heavy Food and Alcohol Part of the pleasure of flying commercially, especially if you fly business or first class, is taking advantages of the food and drinks. If you want to avoid jet lag, though, you should think twice. Eating heavy food will only make the jet lag worse. It isn't good to drink alcohol during a flight, either, because it may make you drowsy. Wait until your body adjusts before you decide to have heavy food or drink alcohol. What is the main idea of the passage?

Tom, a 15-year-old boy, couldn't hear anything after the whole night computer games and MP3 listening. He was excited and yelled after the MP3. When he walked out of his room the next morning, he could hear nothing about his mother's words. His mother sent him to the doctor at once. It was moderate hearing loss . Do you have an MP3 player? Do you use it to listen to your favorite music? A survey shows that lots of young people enjoy listening to their MP3 players. And they always listen to them at high volumes . There are about 100 million people listening to MP3 players in Europe every day. Most of them are young people. Scientists have found that if people listen to MP3 players at a very high volume for more than five hours a week, they could lose their hearing in five years. High-volume music can keep people excited, so young people would like to keep their players high. It's too bad for the ears. So the MP3 listeners should keep the player within safe volume levels, no higher than 60~70 of full capacity . If people near you can hear your MP3, that means you are keeping your MP3 at a very high volume, turn it down, please! What didn't Tom do before he had moderate hearing loss?

Frank Woolworth was born in Rodman, New York, in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be a farmer. He took a short business course, and went to work as a salesman in a large city. Woolworth realized he had a natural skill for showing goods to attract people's interest, but he soon learned something more important. One day his boss told him to sell some odds and ends ( ) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared. Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly from the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half. By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world. He always runs his business according to strict rules, of which the most important was: "THE CUSTOMER IS ALWAYS RIGHT."www.ks5u.com Frank sold the odds and ends quickly because _ .

At some time in your life you may have a strong desire to do something strange or terrible. However, chances are that you don't act on your impulse , but let it pass instead. You know that to take the action is wrong in some way and that other people will not accept your behavior. Perhaps the most interesting thing about the phenomenon of taboo behavior is how it can change over the years within the same society, how certain behavior and attitudes once considered taboo can become perfectly acceptable and natural at another point in time. Topics such as death, for example, were once considered so upsetting and unpleasant that it was a taboo to even talk about them. Now with the publication of important books such as On Death and Dying and Learning to Say Goodbye, people have become more aware of the importance of expressing feelings about death and, as a result, are more willing to talk about this taboo subject. One of the newest taboos in American society is the topic of fat. Unlike many other taboos, fat is a topic that Americans talk about constantly. It's not taboo to talk about fat; it's taboo to be fat. The "in" look is thin, not fat. In the work world, most companies prefer youthful-looking, trim executives to sell their image as well as their products to the public. The thin look is associated with youth, vigor, and success. The fat person, on the other hand, is thought of as lazy and lacking in energy, self-discipline, and self-respect. In an image-conscious society like the U.S., thin is "in", fat is "out". It's not surprising, then, that millions of Americans have become obsessed with staying slim and "in shape". The pursuit of a youthful physical appearance is not, however, the only reason for America's fascination with diet and exercise. Recent research has shown the critical importance of diet and exercise for personal health. As in most technologically developed nations, the life-style of North Americans has changed dramatically during the course of the last century. Modern machines do all the physical labor that people were once forced to do by hand. Cars and buses transport us quickly from point to point. As a result of inactivity and disuse, people's bodies can easily become weak and vulnerable to disease. In an effort to avoid such a fate, millions of Americans are spending more of their time exercising. The main reason the passage gives for why so many Americans are exercising regularly is _ .

In American crime movies, policemen search crime scenes for anything that might belong to a criminal-- bits of fingernail , blood or hair-- in order to find out who they are. What they hope to find is the key to their identity--their DNA. DNA is the chemical that contains a person's genetic makeup. Every person, except for identical twins, has unique DNA information. That is why we can use it to identify someone. There is no doubt that DNA evidence is becoming a very powerful tool for law enforcement officers. In the US, all 50 states and the federal government keep DNA databases of some criminals after they have been convicted . Whenever a crime happens, the police collect DNA from the crime scene and compare this with samples they already have in the criminal database. If they match any suspect in the database, then they've caught their criminal. Even if they don't, the DNA sample can still be used to determine the person's sex, height, hair and eye color1 and other characteristics. This helps police to create a physical profile of the criminal. Some people feel that the database should be made bigger to contain everyone's DNA and help to solve many more crimes. This would also avoid mistakes when someone is wrongly convicted of a crime. DNA doesn't make mistakes. However, other people are worried that it would violate their privacy. Someone's DNA can be used to gather information such as the person's family and ethnic background, whether he or she has a gene mutation or certain genetic diseases, and other personal issues. People are afraid that this information might be used inappropriately. They may fear that employers might read it and treat them differently. People may also be afraid that personal data might get into the hands of insurance firms or loan companies. For example, if they knew from your DNA that you had a genetic risk of a serious disease, they might be able to refuse you life insurance, a loan, or even a job. Clearly, the use of DNA evidence will continue to help the police solve crimes. However, social and ethical concerns about DNA will also remain a topic of debate. What is the great concern over the DNA database according to the article?

Scientists studying the impact of climate change on the Arctic need to consider ways to reduce their own carbon footprints , says Ryan Brook, a researcher who regularly flies north to study the health of caribous .He calls on scientists to show leadership by examining and sharing ways to reduce the impact of working in polar regions. "The importance of the research is not at question here. It is important to our understanding of and adapting to climate change. But we need to think about better approaches," says Brook. "This is an issue for all scientists, though polar researchers often travel particularly long distances using commercial air travel. We also rely extensively on small aircraft, icebreakers, and snowmobiles, all of which produce large amounts of carbon." Brook studies the health of caribou herds in Nunavut and Northwest Territories. He works with northern wildlife managers. This work typically takes him north five or six times per year and when he calculated his own carbon footprint, he was not happy with the result. "My research footprints are about the same as the annual footprints of an average Toronto resident. Basically, I have two footprints -- my own personal life, which is moderate, and my research footprint." Climate scientists can rightly argue that Arctic research is a specialized field and the community of scientists who travel north is relatively small. Even if all scientists working in the north reduced their carbon emissions, it would not make a big impact on the global scale. For Brook, it's the option that matters. There are ways researchers can reduce the amount of carbon they use. Some helicopters use less fuel than others. Solar and wind power are alternatives to gas-fired generators. And while carbon offsets don't reduce the amount of carbon emitted, they are an easy first step. "There aren't necessarily any easy answers, but we need to start talking about it," says Brook. "This is particularly important for the next generation of scientists being trained and I hope to see them become leaders in this issue." What's the main idea of the text?

LV Tiantian, a graduate student majoring in ethics at Jiangsu University in Zhenjiang,has spent years reading Aristotle and Plato.She has debated with classmates about the meaning of "happiness" and in written papers about the role of morality in society.But as LV prepares to enter the professional world,she's finding that her background isn't getting her a lot of job interviews."Employers do not seem to value the theories and philosophy that we liberal arts majors have learned,"said LV,24."I earned far fewer interview chances than those majoring in more practical subjects in science and technology." According to a 2009 survey conducted by Zhongqing Shijia Survey Net and China Enterprise News,science graduates enjoy higher employment rates and salaries than liberal arts students do.Things aren't much different overseas.The New York Times reports that job listings for professors in English,literature and foreign languages dropped 21 percent for the 2008-2009 academic year-the biggest decline in 34 years.As a result,some American educators are calling for universities to abandon the "old Ivory Tower view of liberal education".They want to put more emphasis on the practical and economic aspects of education. Chinese educational experts tend to agree up to a point.But abandoning emphasis on the humanities altogether,they say,brings great risk."The liberal arts do not generate any tangible material wealth,but it does convey social values.And it passes spiritual heritage from one generation to another,"said Niu Dakui,an expert on education at Beijing Normal University."If the humanities are _ ,our youngsters will lose their way." Anthony T.Kronman,a professor of law at Yale,goes even further.He argues that the greed,irresponsibility and fraud that put the world in the current financial mess will only get worse without a new emphasis on the humanities.In his view,this is the time to re-examine "what we care about and what we value"--something that the humanities" are extremely well-equipped to address". How this debate plays out may very well determine the future of Chinese high school education.Some people want high school students to be able to specialize in science during their high school years.Others think they should get a more rounded education with a substantial number of hours in the arts and humanities. According to the passage,that science graduates have a brighter future in their career than those majoring in humanities is_.

Different people have different colors of skin. Some have black skin, some have yellow skin and some have white skin. There is a woman in Alaska. Her skin is orange. It is almost the color of orange juice. How did her skin become orange? She ate lots of tomatoes, carrots and squash . She ate too many orange things. That's why her skin turned orange. The woman doesn't want her skin to be orange, so she goes to see the doctor. The doctor says, " Stop eating orange things, Eat some green things." The woman did so, and her skin isn't orange any more. The woman goes to see a doctor because _ .

The US recession has opened up the biggest gap between male and female unemployment rates since records began in 1948, as men bear the blow of the economy's decline. Men have lost almost 80% of the 5.1 million jobs since the recession started, pushing the male unemployment rate to 8.8%. The female jobless rate has hit 7%. This is a dramatic change of the trend over the past few years, where the rates of male and female unemployment barely differed, at about 5%. It also means that women could soon overtake men as the majority of the prefix = st1 /USlabour force. Men have been badly hurt because they dominate those industries that have been affected: 9 in every 10 construction workers are male, as are 7 in every 10 manufacturing workers. These two sectors alone have lost almost 2.5 million jobs. Women, in contrast, tend to hold more stable jobs and make up 75% of the most unaffected sectors of all: education and healthcare. "It protects them a little bit and softens the blow," said Francine Blau, a labour market economist at CornellUniversity. "I think we are going to see this pattern until the recovery." The widening gap between male and female joblessness means many US families are totally reliant on the income the woman brings in. Since women earn on average 20% less than men, that is putting extra stress on many households. What does Francine Blau really mean by his words?

A teddy bear from Cumbria is launching into space to raise cash for charity . Terence, an experienced traveller who has been to Iraq, will be the guest of honour on aviation legend Burt Rutan's Spaceship One when it flies above Earth. The mission takes off from California on September 29, and on his return the cuddly toy will be auctioned off in aid of the North Air Ambulance Appeal . Spaceship One is the world's first private spacecraft, and is competing for a prestigious space travel prize. Chief executive of the Great North Air Ambulance Service (GNAAS), Graham Pickering, said "flying officer" Terence had been handed over to the RAF six months ago and staff had been receiving postcards from him ever since. He said, "Terence was a fundraising idea that really took off. We have received pictures of him in a U2 craft, trying parachuting and even looking drunk and disorderly. When the RAF finally discharge him he will be a very rare bear indeed--we just hope he does not burn up on re-entry to Earth." GNAAS, which needs charitable donations of more than PS2m a year, has three air ambulances . Peter Bond, spokesman for the Royal Astronomical Society, said Terence's safety was not guaranteed. He said, "This is a new and experimental craft and this will only be the second time it has flown. During its first voyage it developed technical problems but hopefully they have now been resolved." Since May, Terence has spent time with members of 100 Squadron based at RAF Leeming in Basra, Iraq, and at air shows with performing fighter planes. Spaceship One will fly 100km (62 miles) above the Earth's surface, just breaking through the planet's atmosphere. If it repeats the feat inside two weeks, it will claim the $10m Ansari X-Prize set up to encourage the private space flight business. Which of the following is true of Spaceship One?

"Spaceship One is the world's first spacecraft.",

SANTO DOMINGO, Domincan Republic ---An infant girl born with a second head bled to death Saturday after complex surgery to remove her partially formed twin , her parents and doctors said. A medical team completed the 11- hour operation Friday night and said 8-week-old Rebecca Martinez died seven hours later. Doctors had warned after the surgery that the girl would be at great risk of death. " We knew this was a very risky surgery , and now we accept what God has decided , " Rebecca's father , 29-year-old Frankin Martinez, said at a news conference with his wife. " Rebecca is no longer with us physically , but no one will forget her." Martinez said the family would bury Rebecca in a private funeral later in the day. The girl lost a lot of blood in the operation, which apparently ( ) caused her to suffer a heart attack , said Dr. Jorge Lazareff , the lead surgeon . Friends and family donated almost 4 gallons of blood for surgeons to use Rebeca's operation "This was not a failure or an error ," Lazareff said . " When we left here last night the girl was in stable condition. At some point in the middle of the night , she started to bleed." Rebecca was born Dec. 10 with the undeveloped head of her twin, an exteremely rare condition known as craniopagus parasticus . Rebecca was the eighth documented case in the world of craniopagus parasiticus, doctors said. All the other infants documented to have had the condition died before birth , making Rebecca\s surgery the first known operation of its kind. Without an operation , Rebecca would have barely been able to lift her head at 3 months old. Her doctors said the pressure from the second head would have prevented her brain from developing. " We always saw Rebecca without the extra part of her body, "er father said after her death. Rebecca was their third child-----along with a 4-year-old boy and a 1-year-old girl. Which of the following would be the best title of the passage?

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

People in cities all over the world shop in supermarkets. Who decides what you buy in the supermarket? Do you decide? Does the supermarket decide? When you enter the supermarket, you see shelves full of food. You walk in the aisles between the shelves. You push a shopping cart and put your food in it. You probably hear soft, slow music as you walk along the aisles. This may be an attempt to please you, so you will enjoy shopping. Some supermarkets want to increase their profits by playing soft and slow music, because the slow music makes you walk slowly and you have more time to buy things. Fresh fruit and vegetables are usually put near the entrance. When you arrive at the supermarket, you think about the kinds of fruit and vegetables you need first. Once you've got that out of the way, you can relax and do the rest of the shopping without any hurry. Besides, if you see fresh goods first, it gives you a "feel good" impression of freshness, so you can not help spending your money. Maybe you go to the meat department then. There is some meat on sale, and you want to find it. The manager of the supermarket knows where customers enter the meat department. The cheaper meat is at the other end of the meat department, away from where the customers enter. You have to walk past all the expensive meat before you find the cheaper meat. Maybe you will buy some of the expensive meat instead of the meat on sale. Most of the food in supermarkets is very attractive. It all says "Buy me quickly!" to the customers. The fresh fruit and vegetables say "Buy me quickly!" as you walk by. The expensive meat says "Buy me quickly!" The supermarket tells you what to buy. Some supermarkets play soft, slow music because it _ .

Chicken feathers are useful, and not just to a chicken. Some go into pillows, coats and other products. But countless chicken feathers go to waste. In the United States, billions of chickens are produced yearly. Most of their feathers are thrown away. But instead of being buried in land, some feathers could find a future in plastics . One of the products they have developed is a flowerpot . It may look like other flowerpots. But the container breaks down in the earth within one to five years. And as it _ , it naturally becomes nutrient in the soil. The environmentally friendly flowerpot is the work of two researchers. Walter Schmidt is with the Agricultural Research Service, part of the United States Agriculture Department. Masud Huda is with the Horticultural Research Institute, a private organization . Walter Schmidt has been working to find uses for chicken feathers since the 1990s. Progress in 2002 showed that plastic made from feathers could be formed like other plastics. He says feathers are much stronger and last longer than another plant material. "Feathers are stronger. By design, feathers are also more durable . And the other part about it is if feathers were twice as heavy, or half as strong, then birds couldn't fly." He points out that traditional flowerpots made from other plastics can last much longer. But he wonders if there is really a need. He says most flowerpots are never re-used. "Why would you want a plastic that you use for a year to last for two hundred years? It makes no sense. You want to match the product with the use." said Walter Schmidt. Walter Schmidt and Masud Huda are now adding another chicken product to their flowerpots -- chicken waste. The waste will add more nutrients to the soil as the pot breaks down. The scientists say they hope their flowerpot will be on the market in a year or two. What do people mainly deal with feathers?

The technology is great. Without it we wouldn't have been able to put a man on the moon, explore the ocean's depths or eat microwave sausages. Computers have revolutionized our lives and they have the power to educate and pass on knowledge. But sometimes this power can create more problems than it solves. Every doctor has had to try their best to calm down patients who've come into their surgery waving an Internet print-out, convinced that they have some rare incurable disease, say, throat cancer. The truth is usually far more ordinary, though: they don't have throat cancer, and it's just that their throats are swollen. Being a graduate of the Internet "school" of medicine does not guarantee accurate self-health-checks. One day Mrs. Almond came to my hospital after feeling faint at work. While I took her blood sample and tried to find out what was wrong, she said calmly, "I know what's wrong;I've got throat cancer. I know there's nothing you doctors can do about it and I've just got to wait until the day comes." As a matter of routine I ordered a chest X-ray. I looked at it and the blood results an hour later. Something wasn't right. "Did your local doctor do an X-ray?" I asked. "Oh, I haven't been to the doctor for years," she replied. "I read about it on a website and the symptoms fitted, so I knew that's what I had." However, some of her symptoms, like the severe cough and weight loss, didn't fit with it--but she'd just ignored this. I looked at the X-ray again, and more tests confirmed it wasn't the cancer but tuberculosis --something that most certainly did need treating, and could be deadly. She was lucky we caught it when we did. Mrs. Almond went pale when I explained she would have to be on treatment for the next six months to ensure that she was fully recovered. It was certainly a lesson for her. " _ ," she said, shaking her head, as I explained that all the people she had come into close contact with would have to be found out and tested. She listed up to about 20, and then I went to my office to type up my notes. Unexpectedly, the computer was not working, so I had to wait until someone from the IT department came to fix it. Typical. Maybe I should have a microwave sausage while I waited? By mentioning the breakdown of the computer, the author probably wants to prove _ .

As we get older, most of us worry about grey hair, wrinkles and maintaining a youthful body. But people often don't realize the voice needs looking after. Here, Mr. Rubin, a voice expert, reveals how to keep your voice youthful. Drink more fluid and avoid spicy food You need water for the vocal cords to vibrate well. The body must be kept hydrated enough to make the vocal cords operate well. Drinking 1.5 liters of water a day at intervals of 15 minutes is very important. Mr. Rubin advises avoiding foods with an annoying effect on the stomach, such as onions, chili, fizzy drinks and chocolate. Rest the throat and talk regularly The vocal cords can be scared if you use your voice during a bad cough. If you have a case of laryngitis with a cold, you should rest your voice for a day or two, and seek medical advice. Simply staying sociable and using your voice is very important. "As older people get less mobile, they can become socially isolated and speak less." says Mr. Rubin. "The elderly need to communicate with people more. By using the vocal cords, they enable the ageing process to slow down. " Improve your posture Good posture is essential to keeping the voice young, so we'd better stand properly. Exercise helps you take deeper breaths as it means there is better airflow through the voice box, producing a stronger tone. Sing in the shower This is one of the best ways to preserve your voice, as it keeps the larynx muscles strong while the steam lubricates the voice box. "Singing is gymnastics for the voice," says Mr. Rubin. Joining a choir is one of the best ways to preserve a youthful tone. What can we learn from the text?

Women work harder than men at university and get better degrees as a result, according to a study at Brunel University. The research, which followed 200 students for four years, found that women consistently outperformed men in their studies even though they had started their courses with almost identical A-level grades. An analysis of the results showed that while 65 percent of female graduates were awarded, only 35 percent of male graduates did as well. Girls are known to outperform boys at school, but this research showed that trend continued at university. Fiona Smith, who led the research, said, "The research shows that the difference has something to do with schools in general." "It also shows something about the inequality for working women in terms of pay and promotion. Women work harder at school, harder at university, and do better at both, but they still receive less pay." The research found that female students were more faithful, less likely to miss lectures, and more likely to believe that their marks reflected their abilities than male students. Female students were also more likely to ask for and receive support from their professors. Women were also more likely to choose their universities because they liked the courses offered. In contrast, men were more likely than women to miss lectures due to "other affairs" and "laziness", and to believe that playing sports was an important part of university life. Generally, people think that women's success comes from more emphasis on coursework, but the research showed that female geographers at Brunel did better in their exams than in their coursework. Dr Smith said, "Most women feel that getting good grades is the most important part of university life. They believe that they need to work harder in order to compete in the male-dominated environment they will encounter at work. Good grades are viewed as an 'insurance policy' for success. Men, on the other hand, prefer going out and playing sports to academic work." "This research shows how important it is to get all young people working hard and teach them the value of higher education," he said. Which of the following about men is TRUE according to the passage?

"They work as hard as women.",
"They spend as much time on courses as women.",
"They play a lot more than women.",

Is It Worth Buying Organic Food? Organic food, grown without artificial chemicals, is increasingly popular nowadays. Consumers have been willing to pay up to twice as much for goods with organic labels . However, if you think paying a little more for organic food gets you a more nutritious and safer product, you might want to save your money. A study led by researchers at Stanford University says that organic products aren't necessarily more nutritious, and they're no less likely to suffer from disease-causing bacteria, either. The latest results, published in the Annuals of Internal Medicine, suggest that buyers may be wasting their money. "We did not find strong evidence that organic food is more nutritious or healthier," says Dr. Crystal Smith-Spangler from Stanford. "So consumers shouldn't assume that one type of food has a lower risk or is safer." For their new study, Smith-Spangler and her colleagues conducted a review of two categories of research, including 17 studies that compared health outcomes between consumers of organic against traditional food products, and 223 studies that analyzed the nutritional content of the foods, including key vitamins, minerals and fats. While the researchers found little difference in nutritional content, they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces. Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards. And both organic and traditional meats, such as chicken and pork, were equally likely to be harmed by bacteria at very low rates. The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids, a healthy fat also found in fish that can reduce the risk of heart disease. However, these nutritional differences were too small, and the researchers were unwilling to make much of them until further studies confirm the trends. Organic food is produced with fewer chemicals and more natural-growing practices, but that doesn't always translate into a more nutritious or healthier product. The U. S. Department of Agriculture (USDA) states that "whether you buy organic or not, finding the freshest foods available may have the biggest effect on taste." Fresh food is at least as good as anything marketed as organic. Smith-Spangler and her colleagues found that _ .

"Lizzie, there's a letter for you!" Emily called up the stairs to her sister. Elizabeth looked down. "Is it from Harvard? They refused my application once." Emily answered, "No, it's from Yale." Quickly, Elizabeth walked downstairs. She took the letter and opened it. "Rejected again," Elizabeth said unhappily. "Who says women can't be doctors?" "They are fools not to accept you. You can't let them stop you, Lizzie," Emily said. "I won't. I'll apply to Geneva Medical College," Elizabeth told her sister. As it turned out, the professors at Geneva Medical College were not fools. They allowed Elizabeth Blackwell to study medicine. In 1848, a year before Elizabeth would graduate, a typhoid epidemic broke out in New York. Elizabeth wrote to Emily. "There's an outbreak of typhoid, and I am going to help. It is dangerous, so if I should not survive, please do me the honor of studying medicine yourself." Emily replied, "Encouraged by your dream and success, I have decided to study in medical school, as well." Having survived the disease, Elizabeth tried to set up a private medical practice. "I graduated first in my class but no one believes a woman can be a good doctor," she said to Emily one day. "All I hear is that doctors should be men, while women should stay home to cook and clean." Emily said worriedly, "I will graduate in June with my medical degree. What shall we do?" Elizabeth thought for a while and replied, "There's a big house in the poor part of our town. We can practice medicine there for people who couldn't afford care." Soon with the help of some friends, Elizabeth and Emily bought the house and opened a hospital for poor women and children. "We'll have an all-women staff ," Elizabeth said. "And later, we'll add a medical college for women!" Emily added. At last, Elizabeth realized her dream of being a doctor. We can learn from the text that Elizabeth _ .

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. This passage suggests that one's hearing _ .

If there were supposed to be holes in your body,you would have been born with them. I do,however,think that ear piercing is not wrong. There is a difference between ear piercing and belly button piercing. Ear piercing is not nearly as dangerous. I would be sick if someone stuck a needle in my belly button. Lee from Illinois: Hi! I live in Illinois. I am 23. I have 12 tattoos and three piercings. I love my tattoos and consider myself an art collector. You would be surprised at who has given me the thumbs up on my art work. People on the street stop me to look at the tattoo on my leg. Most of them don't know what it is. They just think the work itself is great. Subotai from California: I'm not forbidden of self-expression,but when I see high school students getting these piercings, I really wonder. In some cases, the drive is deeper and darker than mere fashion. A friend of mine tried piercing her own tongue with a safety pin. It got infected and she had a tongue the size of a cow's. Jackson from Ohio: I don't think it is wrong, but when people do it all over the place like their face and everything--I think that's ridiculous. People who get the big "dragons that cover the whole body--I don't think that's necessary." When I see naked chicks on guys, I think, "You have no respect for women." Who doesn't think tattoos and piercings except ear piercing are beautiful?

Gray hair is simply a part of the normal aging process, and the rate you go silver is genetically predetermined. Going gray is not associated with earlier death, and premature graying is not, generally speaking, a sign of an illness or ill health in younger adults. There are, however, some specific health conditions associated with gray or white hair, but for most of us, going gray is just a fact of life. Hair color1 comes from the pigment melanin , which determines your individual shade. Hair without any melanin is pure white. The pigment is produced in cells called melanocytes, which inject pigment into the hair. At some point in everyone's lifetime, these cells slow down and eventually stop producing color1. Scientists have yet to identify the exact mechanism by which melanocyte cell death occurs. A study of more than 4,000 women and men from 20 countries determined that about 75% of people between the ages of 45 and 65 have some gray hair. In general, people of European descent gray earliest followed by Asians and Africans. It's interesting to note that a lucky 1 in 10 has no gray hair by retirement age. Beginning at age 30, your chances of having gray hair go up 10-20% per decade. It may feel like you have more grays after a stressful event, but that's probably because middle age is basically a series of anxiety-ridden events. Between working, raising kids, and caring for older parents, the "sandwich" years of 45-65 can be stressful, especially for women. They are also when we naturally start to look older. At this point, there is still no silver bullet to keep away the grays. What would be the best title for this passage?

At the recent O&P Extremity Games, I had the opportunity to observe a new generation of athletes with disabilities who were skateboarding and rock climbing. These young people really showed the promise of how rewarding physical activities are! We disabled can - and should be -- as active as anyone else. When we get and stay active, we will feel better, be able to do more, have healthier bodies, and look better. It is a fact that exercise actually produces energy and builds on itself. The more we exercise, the fitter our bodies are, and thus the more energy we have to enjoy recreation and the pleasure of life. Not everyone is cut out to be a competitive athlete, but there are things that we can do to strengthen our physical well-being. Experts recommend that spending as little as 30 minutes each day on physical activities provides benefits including lower risk of heart disease, cancer, high blood pressure, diabetes and other serious diseases. Taking steps to become physically fit does not have to mean acquiring expensive training equipment or a gym membership. Exercise can include simple walking and running, gardening, cleaning the house, swimming, tennis, bicycling (stationary or on the road) and so on. The key is to do it on a regular basis. Healthy lifestyles also require good nutritional habits. When choosing foods, nutritionists advise whole grains, flesh fruits and vegetables, fish, and lean cuts of poultry and meat. The benefits of drinking eight full glasses of water a day are also _ . Water provides the means for nutrients to travel to all our organs, improves skin tone , regulates body temperature and contributes to muscle strength and control, which is confirmed by scientists. Fitness results in completing the tasks of daily living, working a full day, and still having energy to participate in recreational activities. By being fit, you'll find that you enjoy recreational activities even more because you won't be tired or suffer from gore muscles. It is time, folks, to get moving. So let's all get out there and do some exercise! According to the passage, physical activities bring benefits to humans EXCEPT _ .

Happy birthday! Do birthday really make people happy? Of course they do. _ Birthdays celebrate the day when we were born. Besides, that extra candle on the cake suggests another year of growth and maturity --or so we hope.We all like to imagine that we are getting wiser and not just older.Most of us enjoy seeing the wonder of growth in others, as well.For instance, seeing our children develop and learn new things makes us feel proud.For Americans, like people in most cultures, growing up is a wonderful process.But growing old? _ That is a different story. Growing old is not exactly for people in youth-oriented American culture.Most Americans like to look young, act young and feel young. As the old saying goes, "You're young as you feel." Older people joke about how many years young they are, rather than how many years old.People in some countries value the aged as a source of experience and wisdom.But Americans seem to favor those who are young, or at least "young at heart". _ Economically, "senior citizens" often try just to get by.Retirement at the age of 65 brings a sharp decrease in personal income.Social security benefits usually cannot make up the difference.Older people may suffer from poor nutrition , medical care, and housing. Some even have the experience of age discrimination . American sociologist Pat Moore once dressed up like an older person and wandered city streets.She was often treated rudely--even cheated and robbed.However, dressed as a young person, she received much more respect. Unfortunately, the elderly population in America is increasing fast.Why? People are living longer.Fewer babies are being born.And middle-aged "baby boomers" are rapidly entering the group of the elderly.America may soon be a place where wrinkles are "in".Marketing experts are already noticing this growing group of consumers. Growing up is a wonderful thing because _ .
