    In the United States, 30 percent of the adult (成年人) population has a “weight problem”. To many people, the case is clear: we eat too much. But scientific evidence（证据）does little to support the idea. Going back to the America of 1910, we find that people were thinner than today. Yet they ate more food. In those days, people worked harder physically, walked more, used machines much less, and didn’t watch TV.
    Several modern studies, moreover, have shown that fat people do not eat more on average (平均) than thinner people. In fact, some investigations (调查), such as a 1990 study of 3,545 London office workers, show that fatter people eat less than slimmer people.
    Studies show that slim people are more active than fat people. A study by a research group of Stanford University School of Medicine found the following interesting facts:
    The more the men ran, the more fat they lost.
    The more they ran, the more they ate.
    Thus, those who ran the most ate the most, yet lost the greatest amount of body fat.
    小题1:What kind of physical problem do many adult Americans have?
    A．They are too thin.B．They work too hard.
    C．They are too fat.D．They lose too much fat.
    小题2:Which of the following words can take the place of the word “slim” in this passage?
    A．poorB．thinC．healthyD．rich
    小题3:Compared with the adult American population today, the Americans of 1910 ______.
    A．ate more food and had more activitiesB．ate less food but had more activities
    C．ate less food and had less physical activitiesD．had more weight problems
    小题4:What have modern medical and scientific researches reported to us?
    A．Fat people eat less food and are less active.
    B．Fat people eat more food than slim people but are less active.
    C．Fat people eat more food than slim people but are more active.
    D．Thin people run less, but have greater increase in food intake.

    You feel generally depressed and unable to concentrate. Your pattern of daily activity may change：you find yourself awake and active in the middle of the night；you sleep late into the day.  You stay in your room and have little contact with people except with those who speak your language. In your mind，you criticize the people around you；You are constantly comparing between life here and the perfect life back home. Above a11, you are homesick almost all the time.
    If you ever find yourself behaving in these ways，you are probably suffering from culture shock. Culture shock is a psychological condition that sometimes has physical effects. It affects people who have moved away from an environment where they know how to live into a new environment where much is unfamiliar to them-the food，the weather, the language，and especially the unwritten rules for social behavior.
    Culture shock is caused. therefore，by a lack of familiarity with the system of rules that the new society uses for everyday living. Language is an obvious example of one type of these rules. If your language is limited，even the simplest task can suddenly become difficult for you. However, knowledge of the language doesn’t make you free from the effects of culture shock as many Britons in the United States and many Americans in Britain will experience. Most people are unaware that each culture has its own rules for social behavior；they certainly think that polite， civilized people behave the same way worldwide. This mistaken belief will cause you to behave and judge the behavior of others according to the rules you learned as a member of your own culture. If the rules are different, then people will misunderstand your behavior, and you will misunderstand theirs.
    How can you deal with culture shock? First, you need to realize that every newcomer suffers from some culture shock. You’re not the only case. Second，remember that culture shock can be cured. The process of recovery will start as you begin to become used to the new culture. Of course learning the language will help remove the obstacles to communication and will ease the job of making Mends with people. Recognizing and learning the new cultural rules of behavior, however, may be just as important. You’ll still have emotional reactions to unfamiliar situations but you’11 find yourself making jokes about them rather than condemning the entire society as “stupid.” The jokes are a good sign：they show that you are recovering.
    小题1:What’s the main idea of the first paragraph?
    A．the causes of culture shock
    B．some signs of culture shock
    C．the cure for culture shock
    D．an explanation of culture shock
    小题2:What does the underlined word obstacles mean?
    A．things that make a task easy
    B．things that make at ask enjoyable
    C．things that make a task difficult
    D．things that make at ask funny
    小题3:What can be concluded when you find yourself making jokes about new culture?
    A．You are about to recover from culture shock.
    B．You have completely got rid of culture shock.
    C．You never suffered from culture shock before.
    D．You’re in culture shock for many years.
    小题4: Which of the following statements is true according to the passage?
    A．The passage suggests that culture shock makes you miss your family badly.
    B．A good knowledge of the language will prevent you suffering from culture shock.
    C．In the writer’s opinion，the social rules for polite，civilized behavior are international.
    D．If you have a perfect knowledge of their language, you will never be misunderstood.

    Most schools forbid chewing gum(嚼口香糖), but in a few years they might consider changing that rule. Why? Scientists are finding evidence that gum chewing may be good for your health. It may even help improve your test scores. This exciting research is just beginning. And in the meantime, companies are also experimenting with adding vitamins, minerals, medicines, and other substances that could give gum the power to cure headaches and fight everything from serious diseases to bad breath.
    Other researchers are finding that gum might work better than a pill to deliver medicines and other substances into the bloodstream. That’s because the lining (膜) of our cheeks can absorb certain substances more quickly than our stomachs and intestines (肠) can. That discovery could help other researchers develop medicine-containing gums that fight colds, ease headaches, battle nervousness, and
    more. Scientists might even create anti-microbial (抗菌的) gums that cure bad breath.
    Those projects may take years, but gum scientists have already had at least one recent success: They’ve created a gum that could help us stay awake. Researchers have produced a gum called Stay Alert. Each stick has as much caffeine as a cup of coffee. It can take an hour for the caffeine in coffee to have its full effect, but the caffeine in Stay Alert hits in just a few minutes. The gum is easy to transport and it’s stable in cold and hot climates. Unlike a pill, it doesn’t require water to swallow. Those qualities make it easy for soldiers to use. For now, Stay Alert is available only to the military (军队). The manufacturer may one day offer it for sale to the public. People who work at night, such as truck drivers and medical personnel who ride in ambulances, might benefit from a product like Stay Alert.
    小题1:The passage mainly talks about _____.
    A．the rule of forbidding chewing gum in school
    B．new research on chewing gum
    C．different kinds of chewing gum
    D．the relationship between chewing gum and medicine
    小题2:What does the underlined word “hits” in Paragraph 6 probably mean?
    A．Touches. B．Attacks.C．Takes effect. D．Affects badly.
    小题3:According to the passage, Stay Alert is a gum which can help people _____.
    A．stay awakeB．fight colds
    C．cure headachesD．overcome nervousness
    小题4:It can be inferred from the passage that _____.
    A．stay Alert is not easy to store
    B．stay Alert needs water to swallow
    C．stay Alert is available to the public now
    D．we can’t buy gums which cure bad breath now

    A growing number of health, hunger, and sustainable （可持续的）agriculture groups today announced plans for Food Day-a nationwide campaign to change the way Americans eat and think about food．Food Day will encourage people around the country to sponsor or participate in activities that encourage Americans to “eat real” and support healthy, affordable food grown in a sustainable, humane way．
    Organizers hope Food Day will inspire Americans to hold thousands of events in schools, college campuses, houses of worship and even in private homes aimed at fixing America’s food system．A Food Day event could be as small as a parent organizing a vegetable identification contest at a kindergarten class-or as massive as a rally（集会）in a city park, with entertainment and healthy food．Health departments, city councils and other policy makers could use Food Day to launch campaigns, hold hearings, or otherwise address communities food problems．
    The campaign will advocate progress toward five central goals:
    ·Reducing diet-related disease by promoting healthy foods．The American diet is too low in fruits, vegetables, and whole grains and too high in fatty meat, soft drinks and salty packaged and restaurant foods-contributing to hundreds of thousands of premature deaths each year．
    ·Supporting sustainable farms and stopping subsidies to agribusiness．Billions of federal dollars a year would be better spent helping environmentally conscious family farmers than hugeagribusiness operations．
    ·Expanding access to food and alleviating hunger．Far too many Americans don’t know where their next meal is coming from, or have access to fresh produce in their neighborhood．
    ·Reforming factory farms to protect animals and the environment．Farming of animals can and should be done without cruelty, and without degrading the quality of life．
    ·Curbing junk-food marketing to kids．Food companies should not be targeting children with foods that promote tooth decay, obesity and other health problems．
    小题1:What is the best title of the text?
    A．Food Day CampaignB．Eat Real and Keep fit
    C．How to Observe Food DayD．Food Problems in the USA
    小题2:What can we learn from Paragraph 2?
    A．Food problems are not easy to deal with．
    B．Food Day events should be held in public places．
    C．Kindergarten kids are unable to identify vegetables．
    D．People are invited to create their own Food Day events．
    小题3:One of the aims of Food Day is to ____．
    A．target children with junk foodB．operate more agribusiness
    C．increase access to foodD．cancel a series of events
    小题4:The underlined word "curbing" in the last paragraph is closest in meaning to “          ”．
    A．controllingB．enlargingC．evaluatingD．providing
    小题5:We can infer from the text that _____．
    A．Food Day will not help preserve natural resources．
    B．Food Day can be an opportunity to solve food problems．
    C．Food Day has so far achieved all the central goals．
    D．there are different ideas and views about Food Day．

    Many of us believe that a person’s mind becomes less active as he grows older．But this is not true，according to Dr．Lissy F．Jarvik，professor of psychiatry(精神病学)at the University of California，Los Angeles，and a board member of the New Center for Aging at the Veterans Hospital．She has studied the mental functioning of aging persons for several years.For example，one of her studies concerns 136 pairs of twins, who were first examined when they were already 60 years old．As Dr．Jarvik continued the study of the twins into their 70s and 80s，their minds did not generally decline(下降)as was expected．
    However，there was some decline in their psycho-motor(精神运动的)speed． This means that it took them longer to accomplish mental tasks than it used to．But when speed was not a factor，they lost very little intellectual (智力的) ability over the years.In general，Dr．Jarvik’s studies have shown that there is no decline in knowledge or reasoning ability．This is true not only into the 30s and 40s，but into the 60s and 70s as well．
    As for learning new things，and ability to remember，studies by Dr．Jarvik and others show that the old are equal to the young．It is true that older people themselves often complain that their memory is not as good as it once was．However，much of  what we call“loss of memory”is not that at a11．
    In the cases where the older person’s mind really seems to decline，it is not necessarilv a sign of a decay due to becoming old or“senility”．Often it is simply a sign of a depressed emotional state．This depression usually can be got rid of by counseling(咨询)with a psychologist，or medicine which fights depression.
    In American society，when an older person loses something，we tend to call him or her“senile”．But notice that when a younger person loses something，he does not blame it on senility or loss of memory．He finds some other excuse!
    小题1:A long-term study of 136 pairs of twins showed that the only factor that declined over the years was  .
    A．mental healthB．intellectual ability
    C．the amount of knowledgeD．psycho-motor speed
    小题2:According to Dr．Jarvik’s studies，middle-aged and older persons should expect to     .
    A．reason betterB．learn fewer new things
    C．remember lessD．1ose little ability to remember
    小题3:The word“senility”most likely means       .
    A．excellent healthB．weakness in body and mind because of old age
    C．occasional forgetfulnessD．giving up one’s life
    小题4:Both younger and older persons should realize that          .
    A．a sign of a decay due to old age or“senility’’is a common thing
    B．older persons are wiser than younger ones because of different knowledge amount
    C．senility or mental decay due to aging is much less common than most of us believe
    D．a sign of a depressed emotional state is not a reason of decay

    Beginning in October, more than 13,000 McDonald’s (麦当劳)restaurants in America will use a new variety of cooking oil. McDonald’ s aims to make its French fries (油炸食品) and other fried foods healthier.
    The change will not affect the taste or the number of calories in the food. But by changing the cooking oil, McDonald’s says, it hopes to cut by nearly half the amount of trans fatty acids (转换脂肪酸) in French fries and reduce the amount of saturated fats(饱和脂肪) by 16 percent. Scientists believe that trans fatty acids and saturated fats raise cholesterol(胆固醇) levels and increase the risk of heart disease.
    McDonald’s new step is important because McDonald’s is an industry leader and other fast-food chains and food processors may follow the lead.
    For McDonald’s ,the action comes at a time when Americans are becoming more and more concerned about; obesity (肥胖) and are increasing pressure on food companies to offer healthy and nutritious (有营养的) food to consumers.
    After three years of study, McDonald’s officials say they are switching oil that is lower in saturated fats and trans fatty acids. McDonald’s says the change will not cause higher price for consumers.
    Though there is some change, scientists say that the amount of trans fat in foods at McDonald’s and at other fast-food companies is still important.

    A．lower the costs of the products
    B．maker its food taste hatter than ever before

    Too cold for recess?  School policies vary as much as temps
    When is it too cold for schoolchildren to go outside for recess（课间休息）? The answer varies widely based on where a school is located and what the kids are used to.
    Consider:  One northern Minnesota school says it has to be 15 below zero before kids are kept inside. But in areas along the East Coast, temperatures below 35 to 40 degrees could keep kids inside. Canceling recess because of the cold is no small issue considering that much of the USA is trembling through what may be its coldest winter in a generation, according to AccuWeather.
    There is no national temperature standard for when to keep kids inside during the winter months, the U.S. Department of Education says. Decisions are made at the local level, either by principals or school districts.
    Consequently, policies are all over the map:
    ? In International Falls, Minn., the self-described "Icebox of the Nation," where the average high temperature in January is 13 degrees, Falls Elementary School Principal Jerry Hilfer says, "if it's 15 below (or warmer), they go out, no matter what." "At 20 below, it gets iffy," he adds.
    ? In Wicomico County, Md., principals typically keep children indoors when temperatures drop below freezing, or if it's raining or snowing, says Susan Jones, the school system's director of elementary education.
    "That's the bottom line," says Curtis Twilley, principal of Pemberton Elementary School in Salisbury, Md. Twilley says students get little exercise when recess stays indoors. At Pemberton Elementary, the students will typically play board games or computer games in a classroom because the school's gym is occupied with other classes, he says.
    ? For schools in Marquette, Mich., which averages about 12 feet of snow per season, school officials acknowledge students are probably a little more prepared than those in some more mild climates.
    小题1:Which of the following is not true according to the passage_________.
    A．No national temperature standard is made for when to keep kids inside during the winter months.
    B．Susan Jones insists students get little exercise when recess stays indoors.
    C．In Wicomico County, children are kept indoors when temperatures dip below freezing.
    D．Mich has about 12 feet of snow per season on average.
    小题2: Which place calls itself Box of Ice?
    Wicomico County  B. Marquette    C.Salisbury       D. Minn
    小题3: Considering_______, canceling recess In USA because of the cold is a big issue.
    A．different schools have different principles.
    B．much of the USA has very cold winter.
    C．physical activity can boost student performance.
    D．decisions are made at the local level,
    小题4: The underlined word iffy means _______.
    A．uncertain B．surprisingC． seriousD．worse
    小题5: What will be talked about next?
    A．More school policies
    B．The reasons why school policies vary.
    C．Measures to improve the situation.
    D．Necessities to improve the situation

    Most young people enjoy some form of physical activity. It may be walking, cycling, or swimming, or in winter, skating or skiing. It may be games of football, hockey, golf, or tennis. It may be mountaineering.
    Those who have a passion for climbing high and difficult mountains are often looked upon with astonishment. Why are men and women willing to suffer cold and hardship, and to take risks on high mountains? This astonishment is caused probably by the difference between mountaineering and other forms of activity to which men give their relaxation.
    Mountaineering is a sport and not a game. There are no man-made rules, as there are for such games as golf and football. There are, of course, rules of a different kind which it would be dangerous to ignore, but it is this freedom from man-made rules that makes mountaineering attractive to many people. Those who climb mountains are free to use their own methods.
    If we compare mountaineering and other more familiar sports, we might think that one big difference is that mountaineering is not a “team game”. We should be mistaken in this. There are, it is true, no “matches” between “teams” of climbers, but when climbers are on a rock face linked by a rope on which their lives may depend, there is obviously teamwork.
    The mountain climber knows that he may have to fight forces that are stronger and more powerful than man. He has to fight the forces of nature. His sport requires high mental and physical qualities.
    A mountain climber continues to improve in skill year after year. A skier (滑雪者) is probably past his best by the age of thirty, and most international tennis champions are in their early twenties. But it is not unusual for a man of fifty or sixty to climb the highest mountains in Alps. They may take more time than younger men, but they probably climb with more skill and less waste of effort, and they certainly experience equal enjoyment.
    小题1: The main difference between a sport and a game lies in       .
    A．activityB．uniformC．rulesD．skills
    小题2: Mountaineering can be called a team sport because      .
    A．mountaineers depend on each other while climbing
    B．teams compete against each other
    C．it is an Olympic event
    D．there are five climbers on each team
    小题3:Which of the following might be the best title?
    A．How to Climb High MountainsB．Mountain Climbers
    C．Challenging Sports ActivitiesD．Mountaineering

    To get an extra 14 years of life, don't smoke, eat lots of fruits and vegetables, exercise regularly and drink alcohol in a proper amount．That is according to a study published this Monday in the Public Library of Science Medicine Journal．
    After tracking more than 20,000 people aged 45 to 79 years in the United Kingdom from about 1993 to 2007, Kay-Tee Khaw of the University of Cambridge and his colleagues found that people who adopted these four healthy habits lived all average of 14 years longer than those who didn't．
    “We've known for a long time that these behaviors are good things to do, but we've not seen this benefit before, ”said Susan Jebb, head of Nutrition and Health at Britain's Medical Research Council．“The benefit was also seen regardless of whether or not people were fat and what social class they came from．”
    Study participants（参与者）scored a point each for not smoking, regular physical activity, eating five servings of fruits and vegetables a day and moderate alcohol intake．
    Public health experts said they hoped the study would inspire governments to introduce policies helping people to adopt these changes．But because the study only observed people rather than testing specific changes, it would be impossible to conclude that people who suddenly adopted these healthy behaviors would surely gain 14 years．
    “We can't say that any person could gain 14 years by doing these things, ”said Dr．Tim Armstrong, a physical activity expert at the World Health Organization．“The 14 years is an average across the population of what's theoretically（理论上地）possible．”
    “Most people know that things like a good diet matter and that smoking isn't good for them, ”Susan Jebb said．“We need to work on providing people with much more practical support to help them change．”
    小题1:Which of the following DOESN'T belong to the four healthy habits?
    A．Eat five servings of fruits and vegetables a day．
    B．Do proper exercise in the morning every day．
    C．Drinking alcohol in the proper amount every day．
    D．Having a cigarette before going to bed every day．
    小题2:We can learn from the passage that            ．
    A．Susan Jebb did not take part in the study．
    B．the study observed people as well as tested specific changes．
    C．there's no need for people under 45 to adopt these good habits．
    D．only those from first class can benefit from these healthy behaviors．
    小题3:What can be inferred from the passage?
    A．All the people are well aware of the harm of their bad habits．
    B．People aged 45 to 70 have bad habits in the United Kingdom．
    C．Governments should take measures to help people change their bad habits．
    D．People have adopted the four healthy habits after knowing they're good．
    小题4:What would be the best title for this passage?
    A．Smoking and Drinking Cuts You 14 Years
    B．How to Live a Much Healthier Life
    C．Healthy Habits May Give Extra 14 Years
    D．How to Make Your Life Longer Than Others
