    First it was jogging. Then aerobics（有氧运动）. Not too long ago, Americans discovered race walking.
    Now Americans are into a new fitness craze. They’re taking 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 are falling in love with biking because it has speed, the benefits of jogging and beautiful scenery.
    Bicycling is a very appropriate sport, which is important to people who injured their knees while jogging or whose joints are aching from aerobics. And biking is a real awakening for people who have been into race walking in the past. Race walking is as 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 a fixed frame with wide tires and upright handles. Mountain bikes also have many gears（齿轮） 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.
    Costs range from about ＄130 for a bottom-of-the-line bicycle to more than ＄2,700 for an expensive bicycle.
    Mountain biking has attracted some people who race down the sides of mountains like a bat out of hell. But most riders ride slowly and they rarely venture far from home.
    The biking craze has brought an unexpected profit（盈利） to clothing and bicycle accessory（附属品）makers. Last year, bikers paid ＄630 million for biking clothes and accessories.
    Bicycling seems likely to continue its fantastic growth.
    53. Race walking is about as dull as watching paint dry because _______         
    A. race walking is a slow-moving sport
    B. the number of adults who ride for fitness has grown 70 percent in four years.
    C. it has speed, the benefits of jogging and beautiful scenery.
    D. Americans are taking up bicycling.
    54. The bicycling craze has been a profit for _______.
    A. people who want to ride like a bat out of hell
    B. bicycle accessory makers
    C. race walkers
    D. twice as many women as men
    55. What does the underlined word “bottom-of-the-line” mean?
    A. poor       B. modern    C. old        D. cheapest
    56. The main idea of the article is _______
    A. riding a bicycle is one of the most dangerous sports in America
    B. Americans are rolling along
    C. bicycling is the latest fitness craze to hit America
    D. most people in America want to own a hand-made bicycle that can cost more than 2,700

    Moods, say the experts, are feelings that tend to become fixed, influencing one’s outlook for hours, days or even weeks. That’s great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely.
    Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology（药理学）offers a lot of tranquilizers（镇静剂）What many people don’t realize, however, is that scientists have discovered the effectiveness of several non-drug methods to set you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you feel out of sorts, don’t head for the drug-store but try the following methods.
    Of all the mood-altering self-help techniques, aerobic exercise seems to be the most efficient cure for a bad mood. “If you could keep up the exercise, you’d be in high spirits, ” says Kathryn Lance, author of Running for Health and Beauty.
    Researchers have explained biochemical and various other changes that make exercise compare favourably to drugs as a mood raiser. Physical exertion such as housework, however, does little. The key is aerobic exercise—running, cycling, walking, swimming or other repetitive and sustained activities that increase the heart rate, increase blood circulation and improve the body’s use of oxygen. Do some of the activities for at least 20 minutes a session three to five times a week.
    小题1:What is the main subject discussed in the passage?
    A．How to beat a bad mood.B．How to talk bad moods out.
    C．How to do physical exercises.D．How to join in aerobic exercises.
    小题2:According to the passage, all of the statements are true EXCEPT that       
    A．climbing is an efficient cure for a bad mood
    B．moods can have a bad effect on people’s health
    C．aerobic exercise can help people get rid of bad moods
    D．pharmacology has provided people with many tranquilizers
    小题3:“Feel out of sorts” in paragraph 2 could best be replaced by “       ”
    A．put things in orderB．are in high spirits
    C．are in a bad moodD．search for tranquilizers
    小题4: It can be inferred from the passage that        
    A．some drugs are more effective than physical exercises
    B．a person does not need aerobic exercise if he is in a good mood
    C．the best way to overcome a bad mood is to talk to oneself
    D．when in a bad mood, one may not work very efficiently

    Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.
    1. Most historians hold that the Chinese invented fireworks in the 9th century when they
    discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.
    2. In May of 1886, a law led John Pemberton, a pharmacist（药剂师）, to rewrite the formula(配方) for "Pemberton’s French Wine Coca,” his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world –wide drink came into being.
    3. During World War II, scientists at the University of Birmingham invented the magnetron—an important heat-producing part of the microwave oven(微波炉). While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook.

    The Food and Drug Administration is, again, threatening to impose(征税) milk and meat from cloned animals on a public that opposes the technology and its products.
    Respected polls report that more than 60% of Americans think animal cloning is immoral, and that most people said they wouldn’t knowingly eat the products even if the FDA approved them. But because the FDA would allow cloned meat and milk to be sold without identifying labels, consumers wouldn’t be able to avoid them. The FDA has consistently tilted toward those who want cloned milk and meat in our food. Agency officials have repeatedly asserted that science shows cloned milk and meat are safe for humans. But the FDA has never published the complete scientific studies it says support that claim.
    The argument that cloning is safe for animals is unconvincing. Cloned meat and milk offer no public economic benefits. Having cloned cows produce more milk wouldn’t reduce milk prices. US farmers produce more milk than we drink, and the government is required to buy the surplus. Since 2000, dairy support programs have cost taxpayers more than $ 5 billion.
    Most important, this first decision to advance animal biotechnology raises ethical issues beyond the FDA’s expertise（专家意见）. Techniques used to clone animals will advance the ability to clone humans－and create animals with human genes. Neither the agency nor animal scientists are qualified to tell us whether and when it is ethically acceptable for humans to alter the essential nature of animals. We need a national discussion, including ethicists and religious leaders, to consider the wisdom of cloned and transgenic animals. Given the risk of unintended consequences, we should proceed cautiously. The president should halt further FDA action on cloning and set in motion(运作) a process for beginning this broader discussion.
    1. The author’s attitude towards cloning is __________.
    A. standing in the middle      B. opposed     C. approving     D. supportive
    3. In US many people buy cloned foods __________.
    A. to support the new technique
    B. because FDA approved them
    C. because they cannot tell which is cloned food
    D. because they cannot read the labels.
    3. From the text we know that cloning technique ___________.
    A. developed well enough to clone human beings
    B. may cause unintended bad results to human beings
    C. will bring more unexpected economic benefits
    D. is supported by ethicists and religious leaders
    4. What’s the best title of this passage?
    A．Public Is Against Cloned Food     B．Benefits of Cloned Food
    C．Cloned Food Is Illegal            D．Technique in Cloned Food

    The United Nations Children’s Fund (UNICEF) has declared October 15 as Global Handwashing Day in 2005．The first Global Handwashing Day is on October 15 of 2008.Activities are planned over twenty countries to get millions of people in the developing world to wash their hands with soap. Global Handwashing Day is the idea of the Public-Private Partnership for Handwashing with Soap. Partners include the UN Children's Fund, American government agencies, the World Bank and soap makers Unilever and Procter and Gamble. The goal is to create a culture of hand washing with soap.
    Hand washing can prevent the spread of disease. Experts say people around the world wash their hands but very few use soap at so-called critical moments. These include after using the toilet, after cleaning a baby and before touching food.
    When people get germs on their hands, they can infect themselves by touching their eyes, nose or mouth. Then they can infect others.
    The organizers say all soaps are equally effective at removing disease-causing germs. The correct way to wash is to wet your hands with a small amount of water and cover them with soap. Rub it into all areas, including under the fingernails. Rub for at least twenty seconds.Then, rinse well under running water. Finally, dry your hands with a clean cloth or wave them in the air. Soap is important because it increases the time that people spend washing. It also helps to break up the grease and dirt that hold most of the germs.And it usually leaves a pleasant smell,which increases the likelihood that people will wash again.
    Washing with soap before eating and after using the toilet could save more lives than any medicine. It could help reduce cases of diarrhea(痢疾) by almost half. And it could reduce deaths from pneumonia and other breathing infections by one-fourth. Diarrhea is the second leading cause of child deaths, killing more than one and a half million children a year. Pneumonia is the leading cause, killing about two million children under five each year. Hand washing can also prevent the spread of other diseases.
    50.We can learn from Paragraph 1 that _______.
    A.the first Global Handwashing Day was held in 2005
    B.many originations support the idea of Global Handwashing Day  
    C.Global Handwashing Day was founded by many soap makers
    D.the content of Global Handwashing Day is to wash your hand frequently
    51.The underlined phrase “critical moments” in Paragraph 2 refers to _______.
    A.the turning points    
    B.schedules  
    C.the arrangement of a time
    D.the necessary parts in health
    52.The main purpose of the story is to tell us ________.
    A.hand washing is very important
    B.to create a culture of hand washing with soap
    C.germs can infect ourselves and others
    D.soaps play an important role in everyday life
    53.The last paragraph implies that ___________.
    A.a soap is a kind of medicine to prevent a disease
    B.it is important for children to wash hands in a correct way
    C.Pneumonia kills about two million children each year
    D.Diarrhea is the second leading cause of child deaths.

    “Human influenza viruses can survive and be infectious for several days when they are deposited on banknotes,” according to the latest study by Yves Thomas and his colleages in Switzerland. Scientists put different types of flu virus onto Swiss franc notes and found that they could survive from a few hours to more than a week. The results depended on the type of flu virus.
    According to the study, Swiss-banknotes are mostly cotton covered by a nonporous resin(无孔树脂). Banknotes from other countries may be composed of different materials, and this could affect viral transmission. “Whether similar results would be obtained with banknotes from other countries and with different characteristics needs to be studied.” the authors wrote. In an interview with Reuters, Thomas said. “Our studies have convinced us that it is possible to catch the flu from banknotes, but the chances are very, very small and there is no cause for concern among the gneral population,” To be sure, many kinds of frequently touched surfaces could temporarily hide the flu virus. Broadly speaking, scientists consider the risk of transmission in this way to be low. Particularly if hand-washing and other hygiene measures are practiced.
    Three things must happen for a flu virus to be transmitted from one person to another via money. First, a person who is infected with the flu virus must sneeze or cough onto the banknote. Next, an uninfected person would need to touch the money while the virus si still present. Finally, that person would need to put his hand in his mouth or pick his nose, says Thomas. The best defense against infection: follow public health guidelines and wash your hands frequently.
    49. What does the underlined word “this” refers to in the second paragraph?
    A. The time when people stay in a bank.
    B. The fact that banknotes may consist of deferent materials.
    C. The bank where people draw their money.
    D. The country where the banknotes are in circlation.
    50. From the last paragraph, we can know that an infected person should ________.
    A. pay attention to his personal hygiene    B. wash his hands after leaving a bank
    C. be monitored at a bank                D. not cough at a bank
    51. What can we learn from the passage?
    A. Any person who touches banknotes will become infected.
    B. Different flu viruses stay on the surface of banknotes for different lengths of time.
    C. The bank should not allow any infected person to enter.
    D. Only banknotes in Switzerland can transmit the flu virus.
    52. What is the best title for the passage?
    A. Is it Dangerous to Stay in a Bank?
    B. How to Avoid Being Infected with the Flu Virus?
    C. Can You Catch the Flu from Handling Money?
    D. Why Do People Refuse to Use Banknotes in Switzerland?

    British and American scientists are raising genetically modified(转基因的) pigs in the hope of providing organs for transplant(移植) to humans, the project leader wrote in a newspaper Sunday.
    Scientists in London and California have begun conducting the genetic experiments to find a solution to record–long waiting lists for organ transplants, Robert Winston said in an opinion piece written for Britain's Sunday Times.
    In Britain alone, around 8,000 patients are waiting for a transplant.
    "People needing a new heart or liver are waiting for someone else to die – usually a violent death in a traffic accident," Winston wrote in the newspaper. He said his team was "trying to modify pigs so their organs might save the lives of humans."
    The scientists are introducing human genes into the animals to reduce the chances of the organs being rejected by patients, as has been common in previous attempts to use animal tissues, said Winston, who heads the Institute of Reproductive and Developmental Biology at London's Hammersmith Hospital.
    Working with Dr. Carol Redhead of the California Institute of Technology, Winston's team has injected human genes directly into male piglets(猪仔), adding them to the animal's sperm(精子).
    He said that pigs involved in experiments had successfully produced transgenic sperm, but acknowledged that British and European laws had prevented the team from using the pigs to mate.
    The Sunday Times newspaper reported that the experiments would be moved to the United States following difficulties with funding and regulations in Britain. It said the pigs would be bred in Missouri.
    "Our U.S. friends will benefit from our technology and the income we might have produced for Britain will be lost," Winston wrote.
    Some scientists have previously blamed the idea of using animal organs for human transplant, saying the technique risks spreading animal viruses to humans. Winston said his research project is attempting to breed virus-free pigs.
    49. Scientists are introducing human genes into the animals to ____________.
    A. make the organs healthier
    		B. reduce the pain of animals
    C. make the organs live longer
    		D. reduce the chances of rejection
    50. Some scientists have blamed the idea of using animal organs for human transplant because ____________.
    A. the technique is not perfect now
    B. humans may be infected with animal viruses
    C. it is against laws and regulations
    D. it may cause a conflict between humans and animals
    51. According to Winston, it seems ___________ to Britain to move the experiments to the United States.            
    A. a pity
    		B. a pride
    		C. a disaster
    		D. a good idea
    52. It can be inferred from the passage that ____________.
    A. animal organs are commonly used for human transplant now
    B. lots of patients need animal organ transplants now
    C. examples of the animal tissues being rejected have happened
    D. it is not safe to use animal organs for human transplant

    Ⅲ 阅读（共两节。满分40分）
    第一节阅读理解（共15小题；每小题2分，满分30分）
    阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。
    A
    Good health is the most valuable thing a person can have, but one cannot take good health for granted. It is important to remember that the body needs proper care in order to be healthy. There are three things that a person can do to help stay in good shape: eat right food, get enough sleep, and exercise regularly.
    Proper nutrition (营养) is important for good health. Your body cannot work well unless it receives the proper kind of “fuel”. Don't eat too much food with lots of sugar and fat. Eat plenty of foods high in protein (蛋白质) , like meat, fish, eggs and nuts. Vegetables and fruits are very important because they provide necessary vitamins (维他命) and minerals. However, don't overeat. It is not helpful to be overweight.
    Getting the proper amount of sleep is also important. If you don't get enough sleep, you feel tired and easily get angry. You have no energy. Over a long period of time a little amount of sleep may even result in a change of personality. Be sure to allow yourself from seven to nine hours of sleep each night. If you do, your body will feel strong and refreshed, and your mind will be sharp.
    Finally, get plenty of exercise. Exercise firms the body, strengthens the muscles, and prevents you from gaining weight. It also improves your heart and lungs. If you follow a regular exercise program, you will probably increase your life-span (寿命).Any kind of exercise is good. Most sports are excellent for keeping the body in good shapes: basketball, swimming, bicycling, running and so on are good examples. Sports are not only good for your body, but they are enjoyable and interesting, too.
    If everybody were to eat the right foods, get plenty of sleep and exercise regularly, the world would be a happier and healthier place. We would all live to be much older and wiser.
    41. According to the passage,_________.
    A .we should always keep fit
    B. if we were healthy, we could spend our days in doing things with less sleep
    C. one can eat a lot to stay in good shape
    D. one needn't take any exercise if he is healthy
    42. In order to keep good health, ___________ .
    A. we should eat a lot of sweets      
    B. one needs a large amount of fat
    C. people should eat according to the foods nutrition
    D. we must try to sleep now and then
    43. Eating more and sleeping less________.
    A. can keep healthy                 B. is no good for you
    C. gets you more energy           D. will keep your personality
    44.The writer explains ________in this passage.
    A. how to eat                         B. the importance of doing exercise
    C. how to keep healthy             D. what to eat
    45.The title of the article should be___________ .
    A. Eating and Exercising           B. How Vitamins Work in Man's Body
    C. Staying Healthy                   D. Sleeping Well
