If you have ever been rock climbing, you will know that it is not a very easy sport. In fact, you probably felt quite defeated when you first tried to do any serious climbing. Indoor and outdoor rock climbing are both extremely demanding and require practice to get good at. It is one of the most physically and mentally demanding sports. There are three basic types of rock climbing. Top roping is the most common type and the climber need to climb with a partner. The second type, which is very similar to top roping, is called lead climbing. In both of the types, the climber can sit off the wall and rest on the rope. The third type is called bouldering. Bouldering is a type of free climbing without any ropes. This is the most demanding of all climbing types. The climber must be able to complete the climbing without taking a rest on the rope. Believe it or not, climbing is said to be about 75% legs and only 25% arms. To climb efficiently and successfully, a person needs to have a wonderful technique. One of the major rules of rock climbing is to always have three points touching the wall, whether it is both feet and one hand, or one foot and both hands, as it is much easier to have your weight cases will not do the climbing; they only hold you into the wall so that your legs are actually pushing you upward. Also, the closer you are to the wall, the easier it is to climb. Rock climbing may sound a bit too extreme for the everyday person, but it is really an amazing workout. Once you get into the sport, and learn how to position your body and rest your weight, then you can begin to deal with some difficult problems. The great thing about rock climbing is that it is mentally challenging as well. You are constantly analyzing the way your body moves and how to do certain moves on the wall. For anyone who wants to get into shape, rock climbing is a fun and effective way to exercise muscles. While climbing, it is much easier for a rock climber if he _ .

Smoking bans in public places are linked with falls in childhood asthma attacks and preterm births , according to the biggest analysis of the influence of public smoking bans on child health. The finding should remove fears that such laws could have the opposite effect because they may lead people to smoke more at home. Several countries, such as Japan and Australia, have tightened laws on smoking in public places over the last few years. Meanwhile, some countries, such as the Netherlands and Germany, still allow smoking in pubs and restaurants. Only about half of US states have comprehensive bans, and there are few restrictions in poorer nations. Opponents often claim that bans could result in people smoking more at home, which would be worse for their children's health. Asthma is one of the main concerns as second-hand smoke harms children's airways in several ways. Researchers led by Jasper Been at Maastricht University Medical Centre reviewed as many as 11 studies that examined how hospital admissions for childhood asthma and preterm births changed after smoking bans came in. The studies involved more than 2.5 million births, and nearly 250,000 hospital admissions for asthma. The result shows that both asthma admissions and preterm birth rates fell by about 10 percent within a year after smoking restrictions were carried out. The effect on preterm births could also have been caused by pregnant women being more likely to quit or cut down following a public ban, says Been. But Been also says the studies could not completely prove that smoking bans directly caused these changes. However, as a matter of fact, because the analysis included several smoking bans introduced in different countries in different years, and most saw health improvements. Such findings are useful for countries and states where there is ongoing debate about how strict smoking bans should be, especially as hospital care for premature babies is so expensive. This might be one of the most important things to know in order to strengthen legislation . Other studies have shown that rates of heart attack and stroke also tend to fall after smoking bans are introduced. According to the passage, some oppose smoking bans in public places because .

In the famous fairy tale, Snow White eats the Queen's apple and falls victim to a curse; in Shakespeare's novel, Romeo drinks the poison and dies; some ancient Chinese kings took pills that contained mercury, believing that it would make them _ , but they died afterwards. Poison has long been an important part in literature and history, and it seems to always be about evil, danger and death. But how much do you really know about poison? An exhibition, The Power of Poison, opened last month at the American Museum of Natural History in New York, intended to give the audience a more vivid understanding of poison. The exhibition will continue until Feb. 2016, reported The New York Times. The museum tour starts in a rainforest setting, where you can see live examples of some of the most poisonous animals: caterpillars, frogs and spiders. Golden poison frogs, for instance, aren't much bigger than a coin, but their skin is covered in a poison that can cut off the signaling power of your nerves, and a single frog has enough venom to kill 10 grown humans. The exhibition also features interactive activities. In an iPad-based game, visitors are presented with three puzzling illnesses and asked to identify the poisons based on symptoms. In one case, for example, a pet dog is found sick in a backyard and visitors have to figure out whether it was the toad , the leaky batteries in the trash or the dirty pond water that did it. "Poisons can be bad for some things," Michael Novacek, senior vice president of the museum, told NBC News. "Yet they can also be good for others." This is what visitors learn from the last part of the exhibition, which displays how poisons can be used favorably by humans, including for medical treatment. The blood toxins of vampire bats, for example, can prevent blood from clotting , which may protect against strokes. A poisonous chemical found in the yew tree is effective against cancer, which is what led to the invention of a cancer-fighting drug called Taxol. One chemical in the venom of Gila monsters can lower the blood sugar of its victims, so it has been used to treat diabetes. Which of the following statements about the exhibition is TRUE according to the article?
|
[
"The exhibition will lead visitors to a real rainforest.",
"Golden poison frogs are the most poisonous animals on display.",
"Those who visit the exhibition can join in some iPad-based interactive games.",
"Visitors can listen to lectures on recent studies of poisonous animals."

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

John Nash, a Nobel Prize winner and a mathematical genius whose struggle with mental illness was documented in the Oscar-winning film A Beautiful Mind, was killed in a car accident on May 24th, 2015. Born in West Virginia, Nash displayed a keenness for mathematics early in life,independently proving Femret's little theorem before graduating from high school. By the time he turned 30 in 1958,he was an unquestionable academic celebrity. At Princeton, Nash published a 27-page thesis that led to applications to economics, international politics, and evolutionary biology. His signature solution-known as a "Nash Equilibrium "-found that competition among two opponents,not necessarily governed by zero-sum logic. Two opponents can, for instance,each achieve their maximum objectives through cooperating with the other, or gain nothing at all by refusing to cooperate. It is now regarded e, one of the most important social science ideas in the 20th century. In the late 1950s, Nash began a slide into mental illness. By the time Nash was awarded the Nobel Prize in Economics in 1994, he hadn't published a paper in 36 years. But like a child cured of a nightmare by the switch of a light, Nash recovered from his illness seemingly by choosing not to be sick anymore. He continued to work, travel,and speak at conferences for the rest of his life. In 2001, the release of the film A Beautiful Mind,based an Sylvia Nasar's 1998 book of the same name, introduced Nash's unusual life story to an international audience. According to"Nash Equilibrium", what will happen if two opponents refuse to cooperate?

You are probably familiar with the saying:An apple a day keeps the doctor away. A recent research carried out by the Chinese University of Hong Kong may change the saying: An apple a day may keep aging away. The research chose fruit flies , as they share many genes with humans. The fruit flies were either fed normally or had an apple extract added to their diet. It turned out that those fruit flies that were given apple extract lived about 55 days--five days longer than the flies that were normally fed. The research group also found it easier for the flies to walk,climb and move about as they aged. According to the result, the researchers believed that the antioxidants in the apple extract helped clean up dangerous chemicals that cause illnesses,as well as aging. In another study,researchers examined diets of thousands of women. They discovered that those who regularly ate apples were 20 percent less likely to suffer heart illnesses and stroke. The apples' genetic code was discovered recently. It allows scientists to develop nicer and healthier fruits. Researchers are already using the information to grow a kind of apples full of antioxidants that can keep eyes and joints healthy and protect humans against heart illnesses and cancer. Apples that kill the desire to eat could also be produced, with the first"extra-healthy''apples on supermarket shelves within just four or five years. The team that keeps studying apple DNA includes 100 scientists from five countries. Their research also suggests that around 65 million years ago, when dinosaurs began to die off the plant,which would finally become today's apple tree, experienced a great genetic change. The number of many of its genes doubled. The extra genes allowed the apple to get used to worse conditions and go through a different development from peaches,strawberries and other related fruits. What can we infer from the passage?

"People who have the habit of eating apples don't need to see a doctor.",
"Apples that kill the desire to eat are already available in supermarkets now.",

One day,I received a call from a colleague.He was about to give a student a zero for his answer to a physical problem,while the student claimed a perfect score.I was elected as their arbiter .I read the examination problem,"Show how it is possible to determine the height of a tall building with the aid of a barometer ." The student had answered,"Take the barometer to the top of the building,attach a long rope to it,lower it to the street,and then bring it up and measure the length of the rope.The length of it is the height of the building." The student had really answered the question completely,but the answer didn't confirm his competence in physics.I suggested the student try again.I gave him six minutes to answer the question,warning that the answer should show some knowledge of physics.Five minutes later,he said he had many answers and dashed off one,which read "Take the barometer to the top of the building and lean over the edge of the roof.Drop the barometer,timing its fall with a stopwatch,then use the physical formula to calculate the height of the building." At this point,my colleague had to accept it,and then the student made almost full marks.I couldn't help asking the student what the other answers were.He listed many others,and then added,"Probably the best one is to take the barometer to the administrator and say to him,'Sir,here is a fine barometer.If you tell me the height of the building,I will give it to you.'" Then,I asked the student if he really did not know the conventional answer to this question.He admitted that he did,but said that he was fed up with high school and college instructors trying to teach him how to think. The name of the student was Bohr who later was famous all over the world.He won the Nobel Prize in Physics in 1922. The student got a zero at the beginning because _ .

Uncle Li and Uncle Wang are good friends. They live next to each other and their farms are both at the foot of the mountain. So they can help each other. But neither of them likes to use his head. They work hard but they are both poor. Most villagers have built new houses, but they still live in the low and broken houses. They never find out why. Once Uncle Li went to town to buy some medicine for his wife. In the town he heard the apples in a city were expensive. He told Uncle Wang about it as soon as he went back. They decided to carry some apples to the city. They borrowed some money from their friends and bought nearly 1,000 kilograms of apples in the villages and carried them to the city on a tractor . Bad luck! A lot of apples were in the city when they arrived. A few days later they had to sell them at a low price. They felt unhappy and returned to their village. "I can't understand why we sustained losses in business while others always profit " Uncle Li asked one day. "The tractor was too small" Uncle Wang said without thinking. "We'll carry more apples on a truck next time!" "I agree!" said Uncle Li. "How foolish we were!" Uncle Li and Uncle Wang live in the low and broken houses because _ .

Today there are 7 billion people on the earth.By the year 2050 there may be 9.0 billion.We will have a lot more people to feed.We need more food. One way to produce more food is by growing stronger plants.For thousands of years,farmers have made plants better.Every season,they pick the best plants for the next season.It works very slowly.Since1983 scientists have been able to change plants more quickly by changing their genetic material. Foods from plants grown in this way are called genetically modified foods ,or GM foods. By changing the genetic material of a plant,it is possible to make new plants. They make plants which are strong against plant diseases. They can also help in our diseases:a kind of rice is being prepared,for example,which stops people from becoming blind.Rich countries produce GM foods because they are easy to grow and they bring in more money.Poor countries are interested in them because they help produce more food. GM plants are not natural.No one knows how good or bad they are.Making GM foods is only one way of feeding people in 2050.But there are strong feelings against them,because they are unnatural. They may feed people,then hurt them or their children later.But both rich and poor countries are very interested in their use,and they are not going to die.In 2050 we may think differently about them.

Four hundred years ago, an Italian scientist named Galileo Galilei became the first person to see the craters on the moon. Galileo was one of the first people to use a telescope to study the sky. Since then, telescopes have become the most important tool used by astronomers. Scientists never stop finding new ways to make these instruments more powerful. In the next several years, two new telescopes with different purposes are to be used. One of the telescopes, called Pan-STARRS, could save humans from dying out. Nick Kaiser, a scientist who works on the project, says the Pan-STARRS telescope has been designed to find "90 percent of all killer asteroids near Earth". Pan-STARRS, like most telescopes, uses mirrors and lenses to provide pictures of outer space. Giant mirrors are used to "gather" light. They reflect the light onto the lens of a camera, which can then record the image. When completed, Pan-STARRS will include four telescopes which will be put on top of a mountain on the Hawaiian island of Maui. Only one telescope is in place and working now. Each telescope will take pictures of one patch of sky for about 30 seconds, and then move on to another patch. Every night, each telescope will take pictures of about 1,000 patches. Every week, each telescope will have photographed the whole sky. Each of the four telescopes will take pictures of the same patches of sky. One telescope, working alone, may sometimes incorrectly show an asteroid. If there are three other telescopes working, astronomers can use them to see if there really is an asteroid coming our way. By using four telescopes instead of one, scientists hope to get a better picture of space. If a giant asteroid was identified, astronomers would try to break it up long before it reached Earth. The four telescopes will take pictures of the same patches of sky because _ .

No woman can be too rich or too thin. This saying often attributed to(...) the late Duchess of Windsor represents much of the strange spirit of our times. Being thin is assumed as such a virtue. The problem with such a view is that some people actually attempt to live by it. I myself have fantasies of slipping into narrow designer clothes. Consequently, I have been on a diet for the better --or worse-- part of my life. Being rich wouldn't be bad either, but that won't happen unless an unknown dies suddenly in some distant land, leaving me millions of dollars. Where did we go off the track? When did eating butter become a sin , and a little bit of extra flesh unappealing, if not unpleasant? All religions have certain days when people stop from eating and overeating is one of Christianity's seven deadly sins. However, until quite recently, most people had a problem getting enough to eat. In some religious groups, wealth was a symbol of probable high morals, and fatness a sign of wealth and well-being. Today the opposite is true. We have shifted to thinness as our new mark of virtue. The result is that being fat -- or even only somewhat overweight -- is bad because it implies a lack of moral strength. Our obsession with thinness is also fueled by health concerns. It is true that in this country we have more overweight people than ever before, and that in many cases, being overweight correlates with an increased risk of heart and blood vessel disease. These diseases, however, may have as much to do with our way of life and our high-fat diets as with excess weight. And the associated risk of cancer in the digestive system may be more of a dietary problem -- too much fat and a lack of fiber -- than a weight problem. The real concern, then, is not that we weigh too much, but that we neither exercise enough nor eat well. Exercise is necessary for strong bones and both heart and lung health. A balanced diet without a lot of fat can also help the body avoid many diseases. We should surely stop paying so much attention to weight. Simply being thin is not enough. It is actually dangerous if those who get (or already are) thin think they are automatically healthy and thus free from paying attention to their overall life-style. Thinness can be pure vain glory. Swept by the current trend, the author _ .

Americans have developed an olive oil habit. Out to dinner recently, I saw a man dipping his white bread in olive oil and then pouring it all over his salad, saying, "Wow, this is so good for me!" But is olive oil the healthiest fat? No, it's not. You might ask, doesn't it lower cholesterol ? Well, only when you substitute olive oil in equivalent amounts for butter or oils that are higher in saturated fat. Olive oil doesn't lower cholesterol; it just doesn't raise it as much. You may be better off with canola oil. The 1999 Lyon Diet Heart Study found that a Mediterranean diet significantly reduced heart attacks and premature deaths. Many people attributed this to eating a lot of olive oil. But it was increased consumption of canola oil that accounted for these improvements. Also, study participants ate more whole-grain bread, vegetables, fish and fruit, and less meat. Butter and cream were replaced with man-made butter made from canola oil, which has more healthy omega-3 fatty acids than olive oil does. Another study found that olive oil reduced blood flow by 31%. Canola oil and fish oil don't. (You want to increase blood flow to all body parts.) I like the taste of olive oil, and I use it sometimes. It's a healthier fat than many others, but it's not nearly as healthy as canola oil -- or fish oil and flaxseed oil, for that matter, which also have lots of omega-3s. And a tablespoon of any oil has 126 calories. Think about that before you pour it on. It can be inferred that in America _ .

From the moment that an animal is born it has to make decisions. It has to decide which of the things around it are for eating, and which are to be avoided; when to attack and when to run away. The animal is, in fact, playing a complicated and potentially dangerous game with its environment, discomfort or destruction. This is a difficult and unpleasant business and few animals would survive if they had to start from the beginning and learn about the world wholly by trial and error, for there are too many possible decisions which would prove fatal. So we find, in practice, that the game is always arranged in favor of the young animal in one way or another. Either the animal is protected during the early stages of its learning about the world around it, or the knowledge of which way to respond is built into its nervous system from the start. The fact that animals behave sensibly can be attributed partly to what we might call genetic learning, to distinguish it from individual learning that an animal does in the cause of its own life time. Genetic learning is learning by a species as a whole, and it is achieved by selection of those members of each generation that happen to behave in the right way. However, genetic learning depends upon a prediction that the future will more or less exactly resemble the past. The more variable individual experience is likely to be, the less efficient is genetic learning as a means of getting over the problems of the survival game. It is not surprising to find that very few species indeed depend wholly upon genetic learning. In the great majority of animals, behavior is a compound of individual experience added to the action patterns animals are born with.That is why animals can survive. Most animals survive because they can make right decisions by _ .

When you cut your skin, you bleed . If a person loses a lot of blood, he will become ill and may die. Blood is very important. People have always known that. At one time, some people even drank blood to make them strong! When doctors understand how blood goes around inside the body, they try ways of giving blood to people who need it. They take blood from the healthy people and give it to people who need it. This is called "blood transfusion". The blood goes from the arm of the healthy person into the arm of the sick person. But there are two problems. First, it does not always work. Sometimes people die when they have blood transfusion. Later, doctors find that we do not all have the same kind of blood. There are four groups--O, A, B and AB. We all have blood of one of these groups. They also find that they can give any kind of blood to people of group AB. But they find that they must give A-group blood to A-group people and B-group blood to B-group people. I have O-group blood and the doctor told me that I could give blood to anyone else safely. ks5u There is another problem. To give blood of the right kind, doctors have to find a person of the right blood group. Often they can not find a person in time. If they have a way to keep the blood until someone needs it, they can always have the right kind of blood. At first they find they can keep it in bottles for fifteen to twenty days. They do this by making it very cold. Then they find how to keep it longer. In the end they find a way of keeping blood for a very long time. We call a place where we keep money a "bank". We call a place where we keep blood a "blood bank". One day, when you grow up, you may decide to give blood to a "blood bank". In this way you may stop someone from dying. Or perhaps one day you may become ill. You may need blood. The "blood bank" will give it to you. People set up the "blood bank" so that they can _

Security--for the information on your smart phone, as well as for the phone itself--is a hot topic these days.The truth is that you're packing a lot of sensitive information on your phone, and you should keep it safe. When it comes to physical security, iPhone users would do well to download Find My iPhone, a free app from Apple that allows you to visit a website and see your (lost, stolen or misplaced) phone on the map.You can then sound an alarm, send a message that will pop up on its screen, lock the phone or erase all your data. Android does not have an exact equivalent , but there are plenty of alternatives. A free app called Lookout offers the findmyphone feature.The paid version allows you to wipe the data from your phone remotely. Then there is your coffee shop's WiFi network.Anyone with minimal technical expert skill can snoop on people using shared wireless networks, harvesting passwords and other personal data. Lookout will caution you when you've logged on to an insecure network, but cannot protect you once you're there. In order to protect yourself on such networks, you can use a virtual private network, or VPN. This turns all your activity into nonsense to anyone trying to read along with you from across Starbucks. It also keeps websites from tracking you and, if you're travelling, allows you to get access to sites that may be blocked in other countries. If you have an iPhone, the simplest VPN app is probably Hotspot Shield, whose distinguishing feature is said to be that it automatically kicks in each time you start browsing , as opposed to other VPN apps that require you to start them up manually .This matters, because even if you decide you want a VPN app, you want to spend approximately zero time thinking about it. For the most part, _ was true of Hotspot Shield, though occasionally it took a while to connect or temporarily lost connection without warning. I found myself having to turn the app on and off sometimes, which involved setting my phone constantly. If even reading about the settings on your phone drive you crazy, then it is probably best to stay away from a VPN app. But if you're the type who can't resist checking your bank balance from your corner bar, the hassle may be preferable to the risk. By using VPN, users can _ .

Most American children eat potatoes every day, but they don't know which part of potato is most nourishing .Take a sharp knife and cut a very thin slice from it and hold it to the light, and you will see that the potato has skin, an outside rim and the inner part. The outside rim which is right under the skin is most nutritious.But this part is often thrown away with the skin. Even the skin itself is better for food than the inside. When eating a cooked potato, if you choose the inside and leave the outside, you are wasting the best part of it. If you can't eat the whole potato, it is better to eat the outside rim and leave the inner part. A potato has _ .

Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21st-century lifestyle is also loud and, if we don't take notice, it can have an effect on our hearing. Most teenagers don't think about hearing loss. But if you experience any of the followingsymptoms , you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people's expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears. iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of itsmaximum volume , and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal. Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss. Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it's like working in a loud factory all day, being amaintenance person under a jet airplane or using ajackhammer on a building site. Similarly, iPod music can cause a short time orpermanent hearing damage. A loud iPod can cause aruptured eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to theauditory nerves that connect to the brain. If this happens, hearing loss becomes permanent. This passage is mainly about _ .

Perhaps you have seen them on the playground, at preschool drop-off or piano lessons, or even in TV shows like Up All Night. They are the stay-at-home dads, and lately, it seems they're everywhere. The latest research shows that 32 percent of dads regularly care for their children, and among those with preschool-age kids, one in five dads is the primary caregiver. In families where mom works, that figure rises to nearly one in three. Stay-at-home dads have become so common that even toy makers like Mattel are catering to them. A recent study finds that today's full-time fathers aren't trying to be "Mr. Moms". Instead, they're carving out their own unique roles as parents. I spoke with some experienced stay-at-home dads, who agreed that their parenting styles are different. "I do let the kids take more risks on the playground, while my wife tends to get nervous that they'll fall and hurt themselves," says Kyle, 38, an artist. Besides, as there are more and more stay-at-home dads, they are turning to each other for support. They have created Meet Up groups and held Dads Nights Out. Kyle admits he had noticed a change recently. "Several years ago, I was checking out at a store with the kids, and the cashier was very curious why I was buying food instead of my wife. I told her that I was a full-time dad, and she commented, 'Wow, I have never met one of you before.' Now, my next-door neighbor is a dad who works from home and we often trades off watching the kids after school. " As for my own husband, although he admits that being a full-time dad is encouraging, he's also proud of the strong bond with our daughter, which will offer her benefits that last for years. Children wit caring dads tend to have higher intelligence and more confidence, and do better in school. They also are less likely to experience depression or get into trouble, and have better social skills. What change has Kyle noticed recently?

If you've been joining in chat room conversation, or trading e-mail with your e-pals, you have become one of the millions who write in a special short form of English. And you've got a sense of humor about short forms like SOHF(="sense" of humor failure) to describe Internet newcomers who understand you. Across the globe, every night teenagers and their elders are "talking" online -- many of them all talking at the same time. It's fast: try talking to six people at once. It's brief: three or four words per exchange. It takes wit , and quick fingers. Want to enter a conversation? Just type PMFJI(="pardon" me for jumping in). Interested in whom you're talking to? A/S/L, the nearly universal request to know your pal's age, sex and location. You may get 15/M/NY as a response from your pal. If something makes you laugh, say you're OTF(="on" the floor), or LOL(="laughing" out loud), or combine the two into ROTFL(="rolling" on the floor laughing). And when it's time to get back to work or go to bed, you type GTG(got to go) or TTYL(="talk" to you later).People want to write as fast as possible, and they want to get their ideas across as quickly as they can. Capital letters are left in the dust, except when expressing strong feelings, as it takes more time to hold down the "shift" key and use capitals. Punctuation is going, too.

First it was jogging. Then aerobics . Not too long ago, Americans discovered race walking. Now Americans are into a newfitnesscraze. They'retaking up bicycling. Over hills and down mountainsides and across quiet country roads, Americans are busily rolling along. The number of adults who ride for fitness is around 17 million, an increase of 70 percent over four years ago. Twice as many women as men are coming to the sport. Americans arefalling in love withbiking because it has speed, the benefitsofjoggingand beautiful scenery. Bicycling is a very appropriate sport, which is important to people who injured their knees while jogging or whosejointsareachingfrom aerobics. And biking is a real awakening for people who have been into race walking in the past. Race walking isas dull as watching paint dry. The most popular kind of bicycle for people who are new to the sport is the mountain bike, which has afixed framewith wide tires andupright handles. Mountain bikes also have manygears to make it easier to climb hills. About 5 million Americans ride mountain bikes, compared with 200,000 who rode them only five years ago. Costsrangefrom about $130 for abottom-of-the-linebicycle to more than $2,700 for an expensive bicycle. Mountain biking has attracted somepeoplewho race down the sides of mountainslike a bat out of hell. But most riders ride slowly and theyrarelyventurefar from home. The biking craze has brought an unexpected profit to clothing and bicycle accessory makers. Last year, bikers paid $ 630 million for biking clothes and accessories. Bicycling seems likely to continue its fantastic growth. The bicycling craze has been a profit for _ .

If a child has a learning problem before he leaves the Second or Third Grade, it's difficult for him to study well. ADHD is one of the most common learning disabilities. Even with parents and doctors working together without schools' help, it is very hard to get rid of the disability. Sadly, even today, there are many schools that don't know how to deal with the children with these disabilities. Fairfield Primary School is a good place for children that have been diagnosed with ADHD. The teachers really care about all of their students and they are willing to work with parents and doctors in order to help these children. When they see the child want to act up in class, they usually give the child something physical to do in order to get rid of the excess energy. They never punish the child for something that is beyond the child's control. Overall, Fairfield Primary School has all of things that a child with ADHD needs. They provide interesting class games for the child's excess energy. They also provide the school rules the child needs. They give the child a caring environment where they are not kept apart because they are different. This is a very good school for a child who is suffering from one or more of these problems. We believe your child with ADHD can learn, change and succeed if they come to study in Fairfield Primary School. The passage is mainly about _ .

Each summer,you hear news that some sports players are sent to hospitals because it is too hot. Our bodies can't be outside in the sun for a long time. So in hot summers,be careful about playing sports outside. Firstly,to play sports safely in hot weather,you must drink water. Sports drinks are great for athletes,but they have so much sugar that they'll dehydrate you more. However,drinking a few bottles of sports drinks will be good for you. Secondly,be sure to take enough breaks to let your body rest. If your coach doesn't let you take enough breaks in the heat,don't wait until you feel uncomfortable. Just be honest with your coach when you need breaks. Thirdly,when you have a break,don't sit in the sun. With the sun beating down on you,you'll only heat up and sweat more. Take a seat under a tree,or even better,go indoors for a little while. Cooling yourself down can help you stay active longer. Fourthly,remember that the earlier in the day you start your exercise,the cooler it will be. If you can start practice before the sun comes up,you have a few good hours to practise in the cool hours of the morning. Also,the earlier you practise,the earlier you can finish the exercise. If you need more practice time,come back to the field later in the evening,when the sun is setting. Last but not least,you should watch what you eat. Eat food which is high in water,starch and carbonhydrate ,but be sure to get a good balance in your diet. As long as you pay attention to the above,playing sports safely in the heat isn't a difficult thing. Which of the following is true according to the passage?

Most American teenagers can't wait to get rid of their "mental mouth" nickname . They count down the days they can finally take their braces off. However, trendy teenagers in Indonesia, Malaysia and Thailand can't wait to get them on, even if they don't need them. Braces are the latest teenage fashion trend in Southeast Asia. Having a mouthful of metal has become so popular with Asian teens that there have been reports of many teens wearing fake braces. Many Asian beauty shops are now offering to put in cheap fake braces. There are even cheaper do-it-yourself braces such as " Hello Kitty," Mickey Mouse" or others for a price of around $100. Braces are considered a sign of wealth in Southeast Asia. A real set of braces in Bangkok, the capital city of Thailand, for example, will cost around $ 1,200, which is a large amount for the country with a GDP of $345 billion ( a billion is 1,000 million), compared to the US which had a GDP of $1,506 Trillion ( a Trillion is 1,000 billion) last year. While Asian teens may think that their colorful fake braces are cool, experts say that these trendy fashion braces can cause illness and can even lead to death. According to the New York Daily News, fake fashion braces have already been linked to the deaths of two teens in Thailand.A 17-year-old in the northeast city of Khon Kaen died from heart failure caused by a thyroid infection from a pair of fake fashion braces. Police also linked the death of another 14-year-old girl in Chonburi to a pair of fashion braces she had brought from an illegal shop. Although the government is giving warnings about fake braces, the trend has been going strong for at least four years. What's worse, the trend for fake braces shows no sign of slowing down.

These days, if you still think the cellphone is just for talking, you will get laughed at. Yes, it's true, voice-only handsets have become out of date. Today's do-it-all mobiles have a lot in common with the computer. The only difference may be that they fit in your pocket and you pay by the minutes to use them. Some of the things a cellphone can do for you will be available this year: Surf at speed Cellpones that let you use the Web have been around for years. So, what's new? Well, faster third-generation(3G) net works let you surf at anywhere. This then allows a carrier to send video, music, and games to your phone. Possible choices are from LG Electronic VX 8000 and Motorola V 1150. Listen as you go The problem with most cellphone MP3 players is that they hold only a handful of songs. But, that's about to change. Sony Ericsson's new W800i can hold around 150 songs in its 500 MB memory. And Sumsung's SPH-V5400 even comes with a 1.5 GB hard drive. Mobile phones may eventually replace mini-MP3 players, especially for teens. Say cheese Camera cellphones are not new either. But, most of them have limitations: around 1-megapixel . But new technology has made 2-megapixel units more common and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson's K750i, offer limited zoom and focus controls. Others, like LG's recent MMA7110, can even capture 30 minutes of full- motion video. Portable TV You say you like "watching TV"? That's what Sumsung MM-A700 wants to give you. The new model lets users watch popular TV programs--for a fee. Other choices are Nokia's 6620, Sanyo's MM 7400 and NEC's N940.The NEC model lets you watch public TV--no fee. The above are just a handful of what you will see in the coming months. Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator... So what is there that a cellphone can't do? What's the difference between NEC's N940 and other models?

EVERYBODY in this world is different from one another. But do you know that understanding differences can help you better manage your money? As we grow up, we gradually develop a set of our own values or beliefs. These are influenced by society, our family, the education we receive and so on. Once this value system is set up, it's not easy to change later in life. Financial experts say that everyone also has their own belief of how to manage their finances. This is part of our value system and it has a great impact on the way we look after our money. According to our different values, experts put us in three categories. They are: the ant, the cricket and the snail. The ant--works first Just like ants who work heart and soul in summer in order to store food for winter, these people don't care about enjoying the moment. They work very hard and save money they earn so that they can enjoy life when they get old and retire. The ant loves to save but they could make more out of their money if they were willing to invest in some funds and stocks with low risk. The cricket--fun first The cricket wants to enjoy everything now and doesn't think too much about the future. They even borrow money when they really want something. Many young people now belong to this group. These people have little savings. When they get old, they might have problems. They should learn to save and buy insurance. The snail--lives under pressure The snail refers to people who make life difficult for themselves. They take big long-term loans from the bank in order to buy things such as luxury houses. They are happy to take big loans even though they are not sure they can afford it. This can cause problems in the future. They should plan more carefully. We can learn from the text that _ .

Birmingham----The wedding took place in aprefix = st1 /Birminghamhotel. The bride and her father arrived in a new black American sports car. Her father looked nervous and uncomfortable in front of the cameras. The bride wore a silk wedding dress. She smiled nervously at the waiting photographers and went to a room on the first floor where she met her future husband for the very first time. Carla Germaine and Greg Cordell were the winners of a radio station's competition. The aim of the competition was to find two strangers prepared to marry without having met each other. Miss Germaine,23, is a model. Mr. Cordell, 27, is a TV salesman. They were among the two hundred people who entered for a peculiar "experiment" organized by BMRB radio in Birmingham,England. Greg and Carla were among eight finalists who were interviewed live on radio. They took a lie detector test and the station also spoke to their friends and family about their personalities. The competition judges included an astrologer who declared that they were suited. The couple celebrated their wedding with a wedding breakfast and a party for 100 guests in the evening, but not everyone shared their joy. Miss Germaine's mother looked anxious throughout the wedding and Mr. Cordell's parents are reported to be less than delighted. Organizations, including the marriage guidance service Relate, have criticized the marriage. As one person put it, "We have enough problems getting young people to take marriage seriously without this. Marriage should always be about love." The couple are now on a Caribbean honeymoon followed by journalists. Their other prizes include a year's free use of a wonderful apartment in the centre ofBirmingham, and a car. But will it last? How did the couple's parents react to the wedding?

At East China University of Science and Technology, students who finish their food in the dining hall can get a coupon when they return their tray . They can exchange coupons for small gifts, such as books, magazines, mobile phone covers and hand warmers. "It's been a big surprise," said Liang Zhaoyun, 19, a student in the university of Shanghai. "It makes us try our best to finish the food!" But some food in the dining hall is so poorly prepared that students are _ to finish it all. Some schools have paid some attention to it. "The dishes in our canteen are all right, generally speaking. We've tried our best to make it tasty. But of course it's difficult to make all the students love it." said Wang. Other universities also pay attention to the size of food. At Nanjing University, rice is divided into three different-sized bowls that students can choose from. "I like to try different dishes at each meal. So I had to throw away a lot of food because the bowls were too big. But now the dining hall offers small sizes. It's great because I can try different dishes at half price and don't waste so much food," said Fan Peng, a student from Nanjing University. But what if you really can't finish all your food? Some universities also provide a take-away service. If you can't finish all your food, you can get a box to take the leftovers home. Even if you feed the cat, it's not wasted. So you see, if we call on students not to waste food, schools should also improve the service and meal quality. How can the students at East China University of Science and Technology get a coupon?

Celia was shocked. She had always been in good shape during high school, but now, in her first year of college, she was suddenly ten pounds heavier. "My friends and I often had pizza or ice cream when we studied late at night," she said, "and I was always drinking Coke to stay awake." Celia's experience is common. Many students enter college and find it so different that they cannot deal with changes properly. They're away from their parents and in a new stressful environment. Pressures together with freedom to sleep and eat however they please cause many students to experience the "Freshman 15": gaining weight suddenly in their freshman year of college. Most students do not realize that the "Freshman 15" can cause some serious health problems. Of course, college-age adults are still developing bone mass, so gaining some weight is normal. Sudden weight gain, however, puts too much strain on the heart and lungs, resulting in little energy and some difficulty thinking and remembering. In later life, it can lead to heart disease, diabetes, obesity, and possibly cancer. The solution to the "Freshman 15" is simple--pay attention to developing good habits! In general: * Eat normal-sized meals at regular times. Eat slowly and enjoy it, so you don't need to go back for more. * Keep only healthy snacks in your room--and don't snack too often! * Control drinking and smoking. Alcohol has a lot of calories, and smoking too much makes exercise difficult. * Exercise regularly! Even just 30 minutes a day--such as walking quickly to class from your dorm--will make a big difference! What do most college students fail to realize?

Running a marathon Have you ever taken part in a marathon? A marathon is 42km long. It is the longest race in the world. To make the runner's body work, harder training is quite necessary. A runner should start to prepare for a marathon at least three months before. Preparation may have races, many hours of running at different speeds and changes in diet . During the training time the runner must eat a fit diet. The diet should have lots of things needed in training the players. In the early days of training, runners run 80km per week. The running is increased every two or three weeks and at least two long runs per week are needed. Two weeks before the marathon, the training programme becomes less, from 100km per week down to 60km and then to 30km in the final week. On the last two days they may not run at all. Breakfast should be eaten at least three hours before the race. Easily digested food such as cereal , toast and scrambled egg is best, with as much fluid as possible. Runners should drink water about half an hour before the race to keep up the body fluid. According to the passage, when should a marathon runner begin his training?

Getting in touch with nature can help keep people fit, reducing the burden of sickness on the health service, conservation experts say. Natural England is starting a campaign to get people to spend more time outside among the country's wildlife and natural environment. The aim of the campaign is to get people to have more contact with nature by promoting green spaces and encouraging health professionals to incorporate (......) the thought into the advice and care plans that they give to patients. Being close to nature can cut stress and increase physical activity. Dr. William Bird from Natural England said: "Increasing evidence suggests that both physical and mental health are improved through contact with nature. Yet people are having less contact with nature than at any time in the past. This has to change. Children with attention disorders have been shown to improve when they have contact with nature. People recovering from operations have been shown to need fewer painkillers if they look out at green fields." He also said people were more likely to keep up with their regular exercise in natural settings, rather than in a gym or leisure centre. Natural England is working with the BBC and more than 300 partners to promote its campaign, which will be the first of four campaigns to get people more involved in nature. Liz Cleaver, from the BBC, said: "These campaigns now provide the public with the opportunity to get outside and to get actively involved in nature close to where they live. That's great for wildlife --but it's also fantastic for everyone's health and well-being." The campaign has also received support from the government. Dr. Fiona Adshead, England's deputy chief medical officer, said: "I welcome Natural England's commitment to encourage and enable people to make use of the country's outdoor space for physical activity." What attitude does Dr. Fiona Adshead have towards the campaign?

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

As we all know, the ocean moves. But waves breaking on the beach make the ocean fun. When you stand on the shore and look at the waves, it seems like the water is moving towards you. But the water is not really moving forward. The moving you see is wave energy. And wave energy comes from the wind. Let's think about how this works. As wave energy passes through the water, the energy makes particles of water move up and down. Just give you an example of a wave passing under a basketball. We put a basketball on the sea. When the wind blows, a wave comes from behind the basketball. The basketball moves up to the top with the wave. Then the wave continues and leaves the basketball behind. The basketball looks lower, but it doesn't move forward. That's because the wave energy just moves the water which is under the basketball. So why can you see a wave knock you down on the shore?When a wave moves toward the shore, the bottom of the wave slows down because _ meets the ocean floor. But the top, which is called crest , keeps moving. The different action causes the wave to fall over or break onto the shore. If a wave is very large, it carries a lot of energy when it hits the land. As time goes by, waves can break up and carry away the rocks and other things on the shore. Shorelines are changing all the time because of wave action. Which of the following is NOT true according to the passage?

"Wave energy comes from the water.",
"Large waves carry plenty of energy.",

Imagine you're in a dark room, running your fingers over a smooth surface in search of a single dot the size of this period, How high do you think the dot must be for your finger to feel it? Scientists have determined that the human finger is so sensitive it can detect a surface bump just one micron(l0-6m)"high. The human eye, by contrast, can't tell anything much smaller than100 microns.No wonder we rely on touch rather than eyesight when faced with a new roll of toilet paper. Biologically, touch is the mother of all sensory systems.It is an ancient sense in evolution: even the simplest single-celled living things can feel when something brushes up against them and will respond by moving closer or pulling away. It is the first sense aroused during a baby's development and the last to weaken at life's peak. Patients in a deep coma who seem otherwise lost to the world will show skin reaction when touched by a nurse. "Touch ,is so central to what we are that we almost cannot imagine ourselves without it," said Chris Dijkerman."It's 'not like eyesight, where you close your eyes and you don't see anything. _ .It's always there." Long ignored in favor of the sensory heavyweights of eyesight and hearing, the study of touch lately:: has been gaining new concern among scientists.They're exploring the effects of recently reported false touch impressions, of people being made to feel as though they had three arms, for example, with the hope of gaining the true understanding of how the mind works. Others are turning to touch for more practical purposes: to build better touch screen instruments and robot hands, a more well-rounded virtual life.. "There's a fair amount of research into new ways of offloading information onto our sense of touch," said Lynette Jones. "To have your cell phone buzzing (making a low sound) as opposed to ringing turned out to have a lot of advantages in.some situations." Touch is our most active sense, our means of seizing the world and experiencing it 'first hand. Dr.Susan Lederman pointed out that while we can become aware of something by seeing or hear,ing7;-.from a distance and without really trying, if we want to learn about something by means of touch, we must make a move.We must rub the cloth, or pet the cat. Touching is a two-way street, and that's not true for seeing or hearing. If you have a soft object and you squeeze it, you change its shape. The physical world reacts back." Our hands are smart and can do many tasks automatically - button a shirt, fit a key in a lock, play the; piano for others.Dr.Lederman and her colleagues have shown that blindfolded subjects can easily recognize a wide range of common -objects placed.in their hands.But on some feeling tasks, touch is all thumbs (very clumsy). When people are given a raised line drawing of a common object, they're puzzled."If all we've got is outline information;" Dr.Lederman said,."no weight, no texture, no temperature information, well, we're very, very bad with that." Touch also turns out to be easy to fool, Among the sensory tricks now being investigated is something called the Pinocchio illusion. Researchers have found that if they shake the band of the biceps , many people report feeling that their forearm is getting 'longer, their hand floating ever further from their elbow . And if they are told to touch the forefinger of the shaken arm to the tip of their nose, they feel as though their nose was lengthening, too. Which of the following statements is true according to the passage?

Lindsay Binegar of Greenfield, Ohio, made her first $ 100 at the age of four, when she won a prize for showing a pig from her family's farm to the local 4H Club. Most kids would be thrilled to spend that money on toys, but not Lindsay. "I didn't get the money; it went to the bank," she told the Columbus Dispatch. Over the years, Lindsay kept on raising and showing pigs, and kept on winning prizes. Some were $ 100 for small wins, but she won thousands of dollars for championship prizes at county fairs. Before long, she earned an impressive amount of cash--but, aside from a purse when she was 14, Lindsay had never spent a dollar of her savings. By the time she was 18, she had got more than $ 40,000, which she planned to put towards her college education at nearby Ohio University. But her parents said that if she continued living at home while attending school, they wouldn't have to pay for her dorm housing, and would be willing to cover the entire cost of her education. It sounded like a good deal to Lindsay. But what should she do with her savings? Her father had an idea:buy a house, just as he'd done when he was young. He used the house's sale to help him buy the family farm where Lindsay had grown up and raised all those lucrative pigs. Lindsay was able to buy a house in Greenfield, paying for the entire purchase in cash. She did a bit of painting and then rented it out for $ 450 a month. After finishing college, Lindsay plans to marry Heath McNeal, and use the income from her house to buy a block of land and build a new house. But she'll never move too far from home. "I would like to stay in Greenfield," she said. "I just love everybody here. " At her current rate, she'll probably be the town's biggest real estate tycoon by the age of 25. By the time she was 18, Lindsay had got more than $ 40,000 by _ .

Recently a man came to me, because he was told that there is fluid around his heart. After trying many drugs which were of no use to reduce the fluid, the doctor told him the only other choice was to have an operation. He refused because he knew that every illness has a mental cause and that if he had the operation but did not clear the mental cause, the fluid would return. At last, he searched the Internet to find a metaphysical healer , and he found me. The mental cause of his disease was an experience of breaking up five years ago with several friends, whom he had known for over twenty years. This experience broke his heart. Not knowing how to "mend" his broken heart, his body created a "repair" by surrounding his heart with fluid to protect it from the sad feelings. Our work focused on reminding him of the feelings of being loved and forgiving his friends. Months later, his hearts was mended and the fluid disappeared. He left my office after the final session with a smile on his face and a spring in his step. The key is: to create a healthy body, you must be healthy not only in body, but also in mind. To be mentally healthy, you need to build up strong relationships. Creating strong relationships will insure that you are accompanied by a network of loving persons. _ is important for building a support system that lifts your spirits. Even when you are alone, you will not feel lonely or upset. Strong relationships are not spaceships----they are not hard to build. Which of the following views may the writer agree to?

How could we have thought so wrongly of as banana peel that it always hits the garbage? Utility of anything seems to be in the eyes of the beholder. The banana peel hasn't been an exception. What most of us looked at as waste was converted to a thing of utility by Prithwis Mukhopadlyay, a 14-year-old prodigy. This Bengali boy, nourished in the US, Lake Junior High in Woodbury, Minnesota, has come up with an idea to convert banana peels to biogas. . It's well known that almost any organic waste can be converted to biogas. But why biogas from banana peel has hit the news is because it produced five times as much biogas as manure , a commonly used source for producing biogas, in the experiments Prithwis conducted. He filled two airtight containers, one with manure and the other with banana peels. Then he mixed each content with water and connected them to empty jars via pipes to collect the gas produced. He placed a heater next to each jar and measured the gas collected for 60 days. His studies proved that banana peels produced five times more biogas than manure. This project titled 'Comparison analysis: Eco-friendly source of energy for the future,' earned him a spot in Discovery Channel Young Scientist Challenge. This weekend, the young whiz is to showcase his research work along with 40 other finalists at Washington. "Initially, I thought of doing a project that would reduce global warming. Things changed after I visited a biogas plant in a village in India during my summer vacations. It was an amazing experience," Prithwis says. This article probably appeared in a _ magazine.

Education in the United States is compulsory for children up to about the age of sixteen.Most young people stay in school longer than that. Most graduate from high school at the age of 17 or 18. Almost half of these high school graduates continue their education at a college or university.Education for most young people in this country is free up to the time they graduate from high school.There are private schools, but most parents send their children to public schools, where students do not pay tuition . When young people go to college, however,they must pay tuition at a public university or a private university.University costs are going up a lot:private universities have become very expensive because the government does not help them. Who pays? The parents of children in college may have to pay more,or often the students may have to find jobs.These students have to worry about assignments and grades and also about their jobs.If they work too much at their jobs they may be absent from class or miss assignments or make too many errors on tests.They may even fail their courses and have to leave the university. For many students, the problem of getting an education is not just a problem of homework and exams.They also have to make money to pay for tuition.And professors don't teach them how to do that!

ABC News anchor Peter Jennings died on Aug.7, 2005 at home in New York after a brief battle with lung cancer. ABC News anchors said they hope if anything good can be taken from Jennings' death, it is a great awareness of the dangers of smoking. "I want to give a message," Barbara Walters said. "If you have kids who are smoking, tell them that we lost Peter." Lung cancer is the worst killer in America, taking more lives each year than any other cancer, according to the America Cancer Society. About 160,440 Americans die each year of cancer, making up 28 percent of all cancer deaths. More than 87 percent of lung cancers are smoking related. Dr. Derek Raghavan, director of the Cleveland Clinic' s Taussing Cancer Center , said that once a person stops smoking, he starts getting better. Three to five years after quitting, the possibility of getting lung cancer is reduced by half. Warning signs of lung cancer can also be mixed with symptoms connected with long-term smoking. The three main warning signs are an increase of coughing that doesn't clear up, coughing up blood and sharp chest pains. People with those symptoms should see a doctor. Raghavan said there have been promising developments in the treatment of lung cancer, including uses of radiation and surgery and drugs. "But the fact is that stopping smoking is the most important thing we can do," Raghavan said. "There is no treatment that even comes close." To fight against lung cancer, what matters much to smokers is _ .

People are so busy these days that many people have no time to cook. This becomes a problem, because most families love home cooking. The food tastes good and warm, and a family meal brings everyone together. In some families, meals are often the only times everyone sees one another at the same time. Another reason people enjoy home cooking is that it is often a way of showing love. A parent who makes some cookies is not just satisfying a child's sweet tooth. She or he is sending a message. The message says, " I care about you enough to send an hour making cookies that you will eat up in 15 minutes if I let you." There is also something about the smell of home cooking. The smell of home cooking please people of all ages. It makes most of us feel good and loved---- even if we are the ones doing the cooking.

Micro blogs like Weibo are nothing new for the young Chinese. A newspaper in Chengdu did a survey last month. It found that 90 percent of junior high school students use micro blogs. They give students an outlet for emotion. "I use micro blogs to record my life. I let everyone 'see' my feelings and complaints ," said Liu Fangyue, 14, from Xiamen No. 1 Middle School. They have fun with classmates even after school. "I would send a message to praise someone who came first in the exam," said Liu. Teachers also join in the fun. "When I sit down to talk to my students, they may not tell me their real thoughts," said Lu Dongping at Nanning No. 2 Middle School. "But on micro blogs, they are more relaxed. They even make fun of me." You would be wrong if you think micro blogs are all about fun. Zhong Yun from Xiamen Haicang Experimental School sees it as a tool to learn English. The 13-year-old girl follows foreign stars such as Avril Lavigne and Justin Bieber. "In order to understand their English posts, I have to check the dictionary and learn many new words," said Zhong. "Micro blogs widen students' perspectives , but there are rules to follow," said Shi Zhongying, a professor from Beijing Normal University. He shares some of them with micro bloggers. "Manage your time, and don't let micro-blogging affect your studies and health," said Shi. "Don't give out your name, family address or phone number on micro blogs. You should also respect truth and other people's privacy ." Zhong Yun often _ on micro blogs.

What will man be like in the future----in 5000 or even 50,000 years from now? We can only make guesses, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller. Five hundred years is relatively short period of time, so we may assume that man will continue to grow taller. Again, in the modern world we use our brains a great deal. Even so, we still make use of only about 20% of the brain's capacity. As time goes on, however, we shall have to use our brains more and more, and eventually we shall need larger ones! This is likely to bring about a physical change to the head, in particular the forehead, will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over very long period of time it is likely that man's eyes will grow stronger. On the other hand, we tend to make less use of our arms and legs. These, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life. But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. In the future, then, both sexes are likely to be bald. Perhaps all this gives the impression that future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. He will still be a human being, with thoughts and emotions similar to our own. The passage mainly tells us that _ .

For a long time, people who fish have had to rely on luck to catch fish. Even big fishing ships, fitted out with radar and modern equipment, have their share of bad days. Wouldn't it be nice if fish could be trained to come at the call of a whistle the way some days are trained? Well, the days of "fish whistle" may be just _ . Japanese companies are working on methods that will train fish to return to harvest areas at the sound of an underwater whistle. The method works like this: First, fish eggs are hatched in a laboratory. Whenever feeding time arrives, a whistle sounds. The young fish learn to return to their feeding areas at the sound of the whistle. Later, the fish are set free at sea, near special-made under water "barns". There, the whistle-plus-feeding program continues. Being well fed and sheltered, the fish continue to live around the barn. So when fishing time arrives, all the harvesters need to do is to sound the whistle, drop their nets, and draw in a lot of fish. Many countries have closed their offshore fishing waters to ships from other countries. With fish whistle and barns, Japan hopes to become less dependent on importing fish from other countries. From the passage we learn that _ .

Everybody needs blood Have you ever seen buses on the street for donating blood? Medical workers on board collect blood from volunteers. The blood is then stored up and given to people who have lost a large amount of it due to accidents or diseases. Blood is one of the most important substances supporting our lives. But for now, the only way we can get more of it is through donation. And donated blood has its own problems. First of all, certain blood types are extremely rare. Type O negative blood (O-), for example, only exists in 7 percent of people, according to Sunday Times. There are fewer donors and therefore there isn't enough of this type of blood for everybody who needs it. In addition, donated blood comes from various people, which means that it has to be examined carefully for disease such as hepatitis and HIV to make sure that it's safe for transfusion. This is why scientists all over the world have been trying to make blood in labs. And now, someone finally succeeded--Marc Turner at the Scottish National BloodTransfusion Service has produced blood fit for transfusion, reported Forbes. Unlike many other scientists, who have tried to make blood substitutes by mixing up different ingredients together, Turner chose to grow blood directly from human stem cells . He developed a special technique to create a chemical environment similar to that in our bone marrow . This environment encourages stem cells to develop fully into red blood cell. According to Turner, his version of artificial blood is unlikely to contain disease viruses or produce side effects. And the best part is that what he managed to produce was type O- blood. Not only is it a rare blood type, it's also a universal type, which means it can be transfused into any patient. The new blood is scheduled for human tests in 2016. However, Turner stressed that the new study should not be taken as a signal for people to stop donating blood because it could be another 20 years before the artificial blood can be manufactured on a large scale. "It is one thing to bake a cake and another thing to bake a cake 100 times the size," said Turner. "It's not just a matter of putting in 100 times the ingredients." Which of the following words best describes Turner's attitude towards theapplication of his artificial blood?

Isn't it interesting how we expect others to behave in a certain way so we can feel good about ourselves? And then when people don't behave as we want them to, we feel so disappointed and angry --- when really, most times, we're not actually surprised at their actions? We just want those actions to be different --- actions we'd be more comfortable with. This week I shared a friend a wonderful home-cooked meal and a bottle of wine. About the time we got to the freshly-baked cookies, the conversation turned to her somewhat crazy sister. I had to smile, just a little, since her sister-stories had had much the same theme for the last two decades.When her frustration was just about to peak over her sister's latest unbelievably selfish act, I suggested she begin trying "The Law of Patient Acceptance." "How can I possibly accept her behavior?" my friend asked. "Acceptance doesn't necessarily mean tolerance," I shared. "It just means that you accept the person for who they are and you stop knocking yourself out trying to change them." Everyone has these difficult people in their lives from time to time. "Think of it this way," I said. "If you were to go out and buy an ottoman today, thinking you were buying a chair, you'd be really angry that the ottoman was such a pathetic chair. But once you realize what you're dealing with, once you accept the ottoman for what it is and you stop trying to turn it into a chair, your anger largely goes away." You have to accept people for who they are. Even when you've had high hopes that they might have been able to be someone else. "You can't change people," my Mother always said. And she was right. The best we can do is to see people as clearly and objectively as possible. For they rarely change. By mentioning the example of buying an ottoman, the writer intends to explain _ .

Our voice gives away a lot of information about ourselves. It can tell us our gender and age. And now, scientists say that it can also tell us our height. Scientists at Washington University, Indiana University and University of California found that listeners could accurately tell the height of speakers, just by their voices. And the key to this mystery is a sound known as the subglottal resonance . It _ with height and helps us build a mental picture of a person. "The best way to think about subglottal resonances is to imagine blowing into a glass bottle with water. The less water in the bottle, the lower sound," said John Morton, a scientist at Washington University. And it's the same for humans. The frequency of the subglottal resonance depends on the height. The taller we are, the deeper the resonance frequency is. In order to find out whether people could identify the resonance, scientists did experiments. A number of same-sex pairs of different heights were told to read the same sentence aloud. It was played back to listeners who had to choose which one of the pairs was taller. Then, other listeners had to rank the speakers from the shortest to the tallest. The listeners were able to identify the tall people 62.17% of time, much higher than a lucky guess. Why not try the experiment yourself? Find out if your tall friends have deeper voices. Which of the following is TRUE?

Farming is moving indoors, where the sun never shines, where rainfall is irrelevant and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature,humidity,air quality and nutrition. It could be in a New York high- rise or a complex in the Saudi desert. It may be an answer to the world's food problems. The world already is having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those - about 3 billion - are hungry or ill-fed. Food prices, currently increasing, are badly affected by dryness, floods and the cost of energy required to plant, harvest and transport it. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world already are using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6.8 billion to 9 billion. To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to greatly increase crop output. Gertjan Meeuws and three other Dutch bioengineers grow vegetables and house plants in closed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating "day" and "night", but according to the rhythm of the plant. Meeuws says a building of 100 square meters and layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables for the entire population of Ken Bosch, about 140,000 people. Their idea isn't to grow foods that require much space, like corn or potatoes. Sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoor agriculture. And city farming means producing food near the consumer, so there's on need to transport it long distances. What is the purpose of the text ?

If a snake bites you, take a photo with your mobile phone! It save your life. This is the surprising advice of a British cook. One day Henry Jackson was working in a restaurant kitchen. He picked up a dish from a table, and suddenly a snake appeared and bit him on the hand. A few days earlier, the snake came to the restaurant from Asia in a box of bananas. It climbed out of the box and hid under the dish. " I tried to pick it up and it bit me. I threw it away, but it landed in the fridge. So I closed the door." Jackson said. Anyway, Jackson was cool and he took a photo of the snake with his mobile phone. Soon his hand began to ache and he went to hospital. Then his chest began to hurt. Doctors couldn't say what was wrong because they didn't know what kind of snake it was. Then Jackson remembered his mobile phone photo. The doctors sent it to London Zoo. When they knew the kind of snake, they could give Jackson the right medicine, and he left hospital the next day. " So my advice is this: If a snake bits you, pick up your phone. Take its photo first and then call the hospital. Show the photo to the doctors," suggests Mr. Jackson. " Oh, and if the snake doesn't smile for its photo, don't worry!" When the snake bit Mr. Jackson, it was _ .

I'm a Chinese student studying in Canada. I have been a boarder with the Carsons for more than a year and a half. The Carsons live in their own house, which has four bedrooms including the one in the basement which I live in. Judy does all the work in the house and Andrew is responsible for the work in the garden. When they go out in they evening, they often ask me to look after their children. Judy's parents, Mr. and Mrs. Morris, lived in another city. Judy was their only child and naturally they doted on Judy's children. They often sent the children presents. Last April Mr. Morris died. Now that Mrs. Morris was quite alone, I expected that Judy would want her to come and live with them. One day, Margaret, Judy's daughter, told me grandma was coming to live with them and her daddy and mummy would want my room back. The news didn't surprise me and the next day I went to Judy and asked her about it. I said I couldn't think of living in their basement room any longer if it was needed for Mrs. Morris. Judy seemed surprised at first. Then she told me there was no deed for me to move, for they hadn't yet come to any decision about her mother coming to live with them. "Naturally I'm worried about my mother. She has been in poor health." She smiled sadly and added. "To be honest, Andrew and my mother have never got on well. We'll wait a bit and see what happens. Perhaps Mohter will be all right living herself, or perhaps they will both change their minds." That was six months ago. During this time I've heard that Mrs. Morris has had two illnesses and that her health has got worse. A nursing home was mentioned once but Mrs. Morris refused to go there. So up to now she's still living alone and I'm still living in the basement room. Why didn't Mrs. Morris come to live with her daughter's family?

The term "bionic man" came from The Six Million Dollar Man which was a popular TV show in the U.S.A. in the 1970s. It was a story about a former astronaut whose body was rebuilt by using artificial parts after he nearly died. Now, a team of engineers has made a robot by using artificial organs , limbs and other body parts that comes close to a true "bionic man". The parts come from 17 manufacturers around the world. "This is the first time they've been assembled together," says Richard Walker, the director of a robot company. "It's an attempt to show the development of medical science," he says. Walker says the robot has about 60 to 70 percent of the function of a human. It stands six-and-a half feet tall and can step, sit and stand with the help of a walking machine. This kind of machine is used by people who have lost the ability to walk. It also has a functioning heart that beats and circulates artificial blood . Its blood carries oxygen just like human blood. Although the parts are used in the robot work, there is a long way to go. There are some key parts missing. There's no liver, skin or brain for the robot. The robot "Bionic man" in the passage _ .

Looking back on China's road to outer space, people can easily find it has not been very smooth. In the past years, Chinese people have made hard and determined efforts to realize the dream their ancestors had for thousands of years. After China's first satellite into the Earth's orbit in 1970 came four flights of unmanned Shenzhou missions from 1999 to 2002. The country carried out its first one-piloted space flight in October, 2003, making China the third country in the world to have independent human spaceflight ability after the Soviet Union and the United States. Then came another breakthrough on October 12, 2005, when Shenzhou 6, China's second human spaceflight, was launched, with a crew of two astronauts. What's more, the landmark spacewalk done by Zhai Zhigang, one of the three boarding Shenzhou 7, launched on Sept. 25, 2008, leads the country further in its space exploration. Meanwhile, China's moon exploration project, started in 2004, has also been progressing satisfactorily. Fifty years after the Soviet Union launched Sputnik, the world's first man-made satellite, China's first circumlunar satellite Chang'e 1 took off on Oct.24, 2007, which became another milestone in China's space achievements after the above-mentioned manned flights. Chang'e 1 was expected to fulfill four scientific goals, one of which was to probe mineral elements on the moon, especially those not existent on Earth. It's said that the lunar regolith is abundant in helium-3, a clean fuel that may support the Earth's energy demands for more than a century. Nearly 3 years later, Oct. 1, 2010 witnessed the blasting off of Chang'e 2, China's 2nd unmanned lunar probe, marking another step forward in moon exploration. This time the aim is to test the key techniques of Chang'e 3 and Chang'e 4, as a preparation for a soft lunar landing in the future. With great expectations, people all over the world are looking forward to China's greater space achievements. Altogether how many astronauts have made successful spaceflight by Shenzhou spaceship by now?

Studies show that children who eat breakfast do better in school. It doesn't take much further thought to know that adults will feel better and do better at work as well. Whether you work at home, on the farm, at the office, at school, or on the road, it is not a good idea to have no breakfast. If we have no breakfast, we are likely to become tired when our brains and bodies run low on fuel . By mid-morning, a lot of us grab a cup of coffee or eat a sugary candy bar to wake up again. This might work for a few minutes, but by lunch time we are hungry. Eating a good breakfast sets the tone for the rest of the day. Having no breakfast is a popular way to lose weight, but not a smart one. Many people believe that they will lose weight if they have no meals, but that just isn't true; the body expects to be refueled a few times a day, starting with a healthy breakfast. Eating breakfast is good for losing weight. In fact, people who eat breakfast are more likely to keep a healthy weight. A healthy breakfast should have some protein and some fiber . Protein can come from low fat meats, eggs, or beans. Fiber can be found in whole grains, vegetables and fruits. A good example of a healthy breakfast might be something simple like a hard boiled egg, an orange, and a bowl of whole grain cereal with low fat milk. Stay away from sugary foods and white bread because they are digested quickly and will leave you hungry and tired in several hours. Protein and fiber will keep you feeling full until lunch time. According to the passage, we feel tired at work probably because _ .

Mike Maietta was eating lunch when he got a text message from his mom. "Notre Dame," it said. " _ !" Mike, a senior at a Californian high school, shouted with joy. The big envelope meant that the excellent university in Indiana had offered him a place in its Class of 2013. But the $51,300 annual fee is a big trouble. So Mike and his parents are considering offers from several other colleges and are figuring out the costs of tuition, housing and holiday trips home. This year, money is the driving factor for a growing number of high school seniors, who have to decide what colleges to attend this fall. Less jobs and house prices have changed family spending. "We're excited that Mike got into eight great schools," said Mike's father, an engineer at Microsoft. "But if you consider going to school out of state, you've got to think about all of the other costs: moving, flying back and forth for the holidays. You're looking at about $3,000 a year, just for travel." As families weigh their choices, some are going back to financial aid offices hoping help packages can be increased. Rachel Brown was happy to get a thick envelope from New York University (NYU). Although she has always wanted to live in Manhattan, she is seriously considering the University of California San Diego (UCSD), because of the high cost in New York. "The tuition for NYU is twice as much as UCSD," said Rachel, 17. "My mom doesn't want me to have a big debt when I graduate, and I don't want that either. I'd have to take out a loan of $15,000. I'll check and see if there's any way that NYU can offer me any financial aid." More than 7.6 million American students have filled out the Free Application for Students Aid, 19.9 percent increase over last year. This month the Federal Department of Education urged college financial aid officers to give more help to certain families. A record 30,428 students applied for 2,300 places at Stanford, partly because the university increased financial aid for families earning below $10,000. The passage mainly focuses on _

Experts recently suggested that teens should start adopting early bedtimes. Before you dismiss it as a habit suited only for young kids, consider that there are serious advantages in being well-rested. And now, even more research suggests that putting phones away before going to sleep is important to teens' well-being. A new study from Seton Hall University School of Health and Medicine Science found that 62 percent of kids used their smart phones before bed, and it's causing less sleep and poor performance in school. Those teens who text before bedtime tend to go to sleep later, and get up later in the morning. Such behavior can be associated with mental health issues like depression or anxiety. Besides, once teens do receive a text, experts found, they tend to respond right away. Then the text conversation continues -- resulting in an even later bedtime. The study's co-author Dr. Peter Polos says this leads to excessive stimulation at night. Light from electronic devices can block the secretion of melatonin -- a hormone that promotes sleep, which makes sleep difficult in the face of overuse of smart phones at night. It's true! More screen time means less sleep time; other studies have suggested the same idea. As for a final piece of advice, Dr. Sushanth Bhat says, since getting the proper amount of sleep is very important for brain development and learning in the teenage years, our study should encourage parents and guardians to limit adolescent smart phone usage at night. Keep in mind that teens aren't the only ones addicted to their phones! Adults can also benefit from setting a tech curfew for themselves. After all, kids learn by example! The author advises parents to _ .

Our "Mommy and Me" time began two years ago. My next-door neighbor and fellow mother, Christie, and I were out in our front yards, watching seven children of age 6 and under ride their bikes up and down."I wish I could take one of my children out alone," said Christie. Then we worked out a plan: When Christie takes one of her children out, I'll watch her other three. And when she watches two of mine, I'll take someone out. The children were extremely quick to accept the idea of "Mommy and Me" time. Christie's daughter, McKenzie, went first. When she returned, the other children showered her with tons of questions. McKenzie was smiling broadly. Christie looked refreshed and happy. "She's like a different child when there's no one else around,"Christie shared with me quietly. With her mother all to herself, McKenzie didn't have to make an effort to gain attention. Just as Christie had noticed changes in McKenzie, I also discovered something different in each of my children during our alone times. For example, I am always surprised when my daughter, who is seldom close to me, holds my hand frequently. My stuttering son, Tom, doesn't stutter once during our activities since he doesn't have to struggle for a chance to speak. And the other son, Sam, who's always a follower when around other children shines as a leader during our times together. The "Mommy and Me" time allows us to be simply alone and away with each child-talking, sharing, and laughing, which has been the biggest gain. Every child deserves to be an only child at least once in a while. Right after McKenzie came back, the other children were _ .

There are a lot of things you can do to help in your community, whether with your mom's chores, or if a friend is upset. Here are some little things you can do to give a helping hand. Be a volunteer. Being in charitable organizations is a great way to help the poor, like giving away food or money. You can also donate money on some charitable website like Tencent Charity. Put yourself in another person's shoes. It can give a strong reason to help someone else if you show your sympathy. It is the best way to show people that you really care about someone. Try to offer first. When people need your help, they'll probably ask you first. But if you have the chance, try to offer to help before they ask you. This will show that you are willing to help from the start. Think about what might happen if you don't help. More people will feel sad if you just leave them when they need you, you don't want to see people unhappy, do you? It's always nice to lend a hand.

Nutrition influences not only students' grades at school but their growth and development. Improper nutrition is one of the causes of childhood obesity. What can you do to help your child avoid childhood obesity? My first piece of advice is to look in your fridge. What are you buying at the grocery store? Think about it: if you don't buy junk food or snacks, your kids won't eat them at home. Now if you're like me -- both of your kids are at school, you'll know you can't police them every second of the day. This is the time when you'll need to talk to your children about their food choices. If you don't know the right food choices, there are so many free resources on-line to guide you. Try new things. I was very surprised to find out my 4-year-old daughter likes balsamic vinegar -- she calls it the "black sauce". She likes to have it with tomatoes and cucumbers. You just never know what your kids might like. Don't get stressed if you can't always prepare something healthy. You may sometimes leave the house and forget to take something out for dinner, or you are running late and there's no time to cook before you have to take one of the kids somewhere. However, you can still make healthy choices while dining out. Many of the fast food restaurants offer fruit and milk instead of soda. I like to buy organic frozen pizzas from the organic market -- for a quick dinner solution . All the ingredients are natural. What I do is to serve the pizza with something raw: lettuce, cucumbers, tomatoes, or fruit to try to give the kids something healthy with that meal. In closing, take baby steps. Don't try to change your family's eating habits in one go, or you'll go nuts. The writer believes it is very important for parents to _

Some people believe that schools will no longer be necessary in the near future.They said that because of the Internet and other new technology, there is no longer any need for school buildings, classes or teachers.Perhaps this will be true one day, but if the world has no schools, I can 't imagine how our society will be, In fact, we should learn how to use new technology to make schools better.We should invent a new knid of school that is linked to libraries, museums, science centers, labs and even companies.Technological companies should create learning programs for schools.Scientists or professors could give talks through the Internet.TV networks and local stations could develop programs about things students are actually studying in school.Labs could set up websites to show new technology so students could see it on the Internet. Is this a dream? No.There are already many cities where this is beginning to happen.Here the whole city is linked to the Internet, and learning can take place at home, at school, and in the office.Businesses provide programs for the schools and the society.The schools provide computer labs for people without their own computers at home.Because everyone can be on the Internet, older people use it as much as younger ones.And everyone can visit distant libraries and museums as easily as nearby ones.How will this new kind of school change the usual way of learning? It is too early to be sure, but it is very exciting to think about it.Technology will change the way we learn; schools will change as well; and we will all learn something from the Internet. Which of the following sentences is NOT true?

We now think of chocolate as sweet, but once it was bitter. We think of it as a candy, but once it was a medicine. Today, chocolate can be a hot drink, a frozen dessert, or just a snack. Sometimes it is an ingredient in the main course of a meal. Mexicans make a hot chocolate sauce called mole and pour it over chicken. The Mexicans also eat chocolate with spices like chili peppers. Chocolate is a product of the tropical cacao tree. The beans taste so bitter that even the monkeys say "Ugh!" and run away. Workers must first dry and then roast the beans. This removes the bitter taste. The word "chocolate" comes from a Mayan word. The Mayas were an ancient people who once lived in Mexico. They valued the cacao tree. Some used the beans for money, while others crushed them to make a drink. When the Spaniards came to Mexico in the sixteenth century, they started drinking cacao too. Because the drink was strong and bitter, they thought it was a medicine. No one had the idea of adding sugar. The Spaniards took some beans back to Europe and opened cafes. Wealthy people drank cacao and said it was good for the digestion. In the 1800s, the owner of a chocolate factory in England discovered that sugar removed the bitter taste of cacao. It quickly became a cheap and popular drink. Soon afterwards, a factory made the first solid block of sweetened chocolate. Later on, another factory mixed milk and chocolate together. People liked the taste of milk chocolate even better. Besides the chocolate candy bar, one of the most popular American snacks is the chocolate chip cookie. Favorite desserts are chocolate cream pie and of course an ice cream sundae with hot fudge sauce. It can be inferred from the passage that _ .

Food serves as a form of communication in two fundamental ways. Sharing bread or other foods is a common human tradition that can promote unity and trust. Food can also have a specific meaning, and play a significant role in a family or culture's celebrations or traditions. The foods we eat--and when and how we eat them--are often unique to a particular culture or may even differ between rural and urban areas within one country. Sharing bread, whether during a special occasion or at the family dinner table, is a common symbol of togetherness. Many cultures also celebrate birthdays and marriages with cakes that are cut and shared among the guests. Early forms of cake were simply a kind of bread, so this tradition hits its roots in the custom of sharing bread. Food also plays an important role in many New Year celebrations. In the southern United States, pieces of corn bread represent blocks of gold for prosperity in the New Year. In Greece, people share a special cake called vasilopita. A coin is put into the cake, which signifies success in the New Year for the person who receives it. Many cultures have ceremonies to celebrate the birth of a child, and food can play a significant role. In China, when a baby is one month old, families name and welcome their child in a celebration that includes giving red-colored eggs to guests. In many cultures, round foods such as grapes, bread, and moon cakes are eaten at welcome celebrations to represent family unity. Nutrition is necessary for life, so it is not surprising that food is such an important part of different cultures around the world. The author explains the role of food in celebrations by _ .
