    On June 5, 1981 the Centers for Disease Control in Atlanta, U.S. announced the presence of a rare, infectious disease in five American homosexuals(同性恋). Soon doctors were finding similar cases all over the country and the world. The AIDS epidemic(流行病)had officially begun. By 1983 it was clear that AIDS had spread around the world. More than twenty years later, AIDS has left twenty-six million dead and another forty million infected.  AIDS has become the worst medical disaster ever experienced by mankind.
    Hundreds of young people between the ages of 20 and 45 died each week during the early years of the U.S. AIDS. More than 600,000 cases of AIDS have been reported since 1981 in the United States, and it is estimated that there may be as many as 900,000 Americans infected with HIV.
    Though the rate of HIV infections continues to increase in the United States, the number of AIDS cases has fallen sharply since 1996, when antiretroviral drugs came onto the market. Unfortunately, the AIDS epidemic continues today in Africa and much of Asia, where antiretroviral treatment is not available and health care is far from enough. AIDS is the fourth leading cause of death worldwide, and the No. 1 cause of death due to infectious disease.
    HIV, the virus that causes AIDS, was first separated in 1983 by a team at the Pasteur Institute in Paris. That discovery made it possible to develop a test for AIDS and trace back to victims who may have died before doctors were aware of the disease.
    However, scientists still don't know exactly how and where AIDS started. Finding the source of AIDS could be important in developing a vaccine(疫苗) and be important in mapping the future course of the epidemic.
    小题1:It can be inferred from the passage that       
    A．antiretroviral drugs will be obtained easily all over the world
    B．the best way to stop AIDS is to develop a vaccine
    B．scientists will soon find a way to cure AIDS
    D．there will be fewer AIDS cases in the world in the future
    小题2:Which areas are the most worrying places where AIDS spreads quickly? 
    A．Africa.B．Asia.C．The United States.D．France.
    小题3:The number of AIDS cases has greatly decreased in the United States due to the fact
    A．a team at the Pasteur Institute in Paris succeeded in separating HIV
    B．some effective medicine has been invented
    B．scientists understand AIDS better and better.
    D．The rate of HIV infections continue to rise in the United States
    小题4:What's the importance of the discovery of the source of AIDS?
    A．It can be used to develop a test for AIDS.
    B．It can stop HIV forming AIDS.
    B．It can reduce the rate of death caused by AIDS.
    D．It can help develop a drug to prevent AIDS.

    Most of us think that when we step under a shower we’re getting clean．We are, but we’re also giving a home to lots of tiny little creatures we didn’t even know about．
    A showerhead carries thousands of bacteria (细菌) called Mycobacterium．These can cause problems like coughs and tiredness, and a general feeling of poorliness (身体不舒服)．When you turn on the water, the bacteria go from the showerhead onto and into your body．
    This is a finding of Norman R．Pace and his team at the University of Colorado, in the US．The scientists investigated bacteria in all kinds of human environment, including showers．
    Pace's team looked at 45 showerheads in nine American cities．They discovered that 30 percent of them had large amounts of flying Mycobacterium．
    But Pace said that they pose few threats to the health．Only those with a frail (脆弱的) immune (免疫的) system might need to worry．
    He told the New York Times that the bactertia are not as unpleasant as might be thought．He said that having a shower is no more dangerous than anything else we do in the morning．
    But for those who feel sick about the idea of all those microorganisms (微生物), he had some advice．
    Let the water run for 30 seconds before getting into the shower．Why? The number of bacteria is smaller than when the water is just turned on．If that seems like a waste of water, he added that you could also change your showerhead every few months．
    But Pace had good news too．He has also been testing the air in US subways．Apart from iron particles (粒子), which are ground off the track by the wheels of trains, subway air is fresh．The reason is that a train’s movement pumps fresh outdoor air into the tunnels(隧道)．
    Pace explained that he wanted to understand the natural microbial(微生物的) environments of public places．This kind of knowledge might help detect the microbes to be used in a bioterrorist (生物恐怖分子) attack．
    49．According to the finding of Norman R．Pace, after taking a shower, we might ______．
    A．get much dirtier                B．be covered by bacteria
    C．get a frail immune system      D．catch a cough or feel tired
    50．Pace’s research into showers shows that ______．
    A．there is no reason to fear microorganism
    B．shower water contains much less bacteria after being left to run for 30 second
    C．having a shower in the morning is more dangerous than at other time
    D．of 45 showerheads surveyed in nine cities, 30 carried large amounts of Mycobacterium
    51．According to the research of Pace’s team, which of the following contributes to fresh air in US subways?
    A．Train wheels．               B．Iron particles．
    C．The movement of the trains． D．Air conditioners on the trains．
    52．The word “detect” in the last paragraph probably means “______”．
    A．to discover      B．to protect        C．to make   D．to prevent

    And adolescents who slept five hours or less a night were 71 percent more   15  to suffer depression and 48 percent more     16  becoming suicidal, the study said.
    "It is a common perception and societal   17  that adolescents do not need as much sleep as pre-adolescents, yet studies suggest that adolescents may  18  require more sleep," said Gangwisch.
    "Studies have found that adolescents do not go to bed   19  enough to make up for earlier school start times, and transitions to earlier school start times have been shown to be   20  with significant sleep deprivation（剥夺）. "

    Want to be a happy married couple? Consider having kids．
    A new study found that having children boosts happiness．And the more, literally, the merrier．
    But unmarried couples shouldn’t expect to find greater happiness through child-raising．The study, published in the Oct．14 online edition of the Journal of Happiness Studies, suggests that having children has little or no effect on boosting happiness among couples who aren’t hitched(和谐)．
    The findings contradict previous research that suggested that having more offspring doesn't lead to greater happiness and might even make people less satisfied with their lives．One theory behind the conclusion is that parents don’t receive many rewards in return for the hard work of raising children．
    The new study, however, notes that parents say children are one of the most important things in their lives, if not the most important．
    The study found that life satisfaction for married people -- women especially -- goes up the more kids they have．Single, separated and co-habiting people, by contrast, report negative experiences．
    “One is tempted to advance that children make people rich under the ‘right conditions’ -- a time in life when people feel that they are ready, or at least willing, to enter parenthood,” Dr．Luis Angeles, of the University of Glasgow in Scotland, said in a news release from the journal’s publisher．“This time can come at very different moments for different individuals, but a likely signal of its approach may well be the act of marriage．”
    小题1:he underlined word “offspring” in the fourth paragraph can be replaced by _____．
    A．generationB．childrenC．mothersD．marriage
    小题2:The best title of this passage should be _______．
    A．Children Are the Source of Happiness
    B．Are You Happy Married Couple?
    C．Married with Children Paves Way to Happiness
    D．The Right Conditions of Having Children
    小题3:Which of the following can be inferred from the passage?
    A．The more children women have, the happier they are．
    B．The more children the married women have, the more unsatisfied they become．
    C．Raising kids can give any person happiness．
    D．Without marriage, one woman had better not raise kids．
    小题4:In the passage, the underlined part ‘right conditions’ refers to _______．
    A．a time when the couple are ready and willing to become parents
    B．the situation where the family is rich enough to raise a child
    C．the situation where the couple are very happy
    D．a time when the couple thinks raising children can boost happiness

    Drinking wine in moderation improves the IQ and may boost mental agility in old people,according to Japanese researchers.
    A study of the effects of alcohol on the middle aged and elderly found the average IQ of men who drink wine (whether made from grapes or rice) was 3.3 points higher than that of men who do not imbibe.
    Similarly,the IQ of women drinkers showed an improvement of 2.5 points over their teetotal sisters.The findings are part of an ongoing study by Japan’s National Institute for Longevity into the links between human intelligence and what we eat and drink.
    The tests measured general knowledge,powers of judgment and concentration in drinkers and non-drinkers over 40,all living in Aichi prefecture,central Japan,and sharing the same income level-roughly￡50 000 a year—and educational background.All were university graduates.
    But while wine-drinkers appeared to be brighter,the same was not true of those who drank deer,shochu (a local gin) and whisky.
    “The benefits of wine and sake (rice wine) in raising IQ could be due to substances they contain,such as polyphenol,which are believed to slow the ageing process,” Hiroshi Shimokata,head of epidemiology research,said.
    It was premature to conclude,he added,that drinking wine or sake slowed the deterioration of brain functions in the elderly,or warded off senility.The research does,however,suggest that this is one way to stay mentally alert longer.
    But there is a sobering caveat:drinking too much may make you dimmer.“People who drink more than 540 milli-litres (a little over a pint) of sake or wine a day had lower intelligence quotients than those who did not drink at all,”Hiroshi Shimokata said.“Moderation is very important.”
    小题1:Which one is the topic of the passage?
    A．Drinking wine in a large amount improves the IQ of old people.
    B．Drinking wine in a reasonable amount raises the IQ of old people.
    C．Drinking wine in moderation does good to any one.
    D．Drinking wine helps improve the IQ of women.
    小题2:According to the passage,which of the following is NOT wrong?
    A．Every wine drinker’s IQ is 3.3 points higher than that of men who don’t drink.
    B．The IQ of women drinker is 2.5 points lower than that of the non-drinking women.
    C．Drinking beer and whisky cannot improve one’s IQ.
    D．Drinking wine can only do good to the IQ of rich old people.
    小题3:The reason why wine and sake can improve IQ is that _________.
    A．wine and sake have special taste
    B．wine and sake can make us excited
    C．wine and sake contain substances considered to slow the ageing process
    D．wine and sake contain something believed to prevent us from ageing
    小题4:From the text,it seems that we can conclude _________.
    A．the more wine we drink,the brighter we are
    B．the less wine we drink,the brighter we are
    C．drinking wine less than 540ml a day,we’ll become dimmer
    D．drinking wine in moderation,we’ll become brighter

    Anti-bird flu contingency (意外事故) measures, including a proposal to separate poultry from humans and a series of traffic and logistics (后勤) measures will be discussed at the Legislative Council's Food Safety and Environmental Hygiene Panel meeting next month. Secretary for Health, Welfare and Food Dr York Chow says the contingency plan would come into force if an outbreak occurred near Hong Kong.
    Speaking on a radio talk show this morning, Dr Chow said the separation of poultry from humans policy, which will be determined after a decision whether to set up a central slaughtering (屠宰) house or several regional ones, would be based on the demand for live chickens.
    He pointed out that at present there were 30,000 live chickens imported from the Mainland and 30,000 supplied locally. If this demand persisted, there would be no central slaughtering house or wholesale point that could handle such an amount and regional slaughtering houses could be the choice.
    He added that building of regional slaughtering houses took time, but stressed the need to study the views of the public and the sector before a final decision was made.
    Regarding avian flu vaccination (种痘) for humans, Dr Chow said it was still being developed. He added that it may not be reliable in the case of an outbreak as records show vaccination can only offer 5% protection against a virus.
    He said Hong Kong had more experience and expertise than neighbouring territories in the fight against viral outbreaks, and was willing to offer them help. He added there was no “boundary” for infectious diseases and close cooperation among different countries had to be maintained to fight against a possible outbreak.
    小题1: It can be inferred from the first paragraph that ______.
    A．the government is planning to take strong action to fight against bird flu
    B．an outbreak which happened near Hong Kong made people very frightened
    C．anti-bird flu contingency measures will come into use next month
    D．Dr York Chow will organize a meeting to discuss the contingency plan
    小题2:According to the passage, the best way to fight against bird flu is to ______.
    A．separate poultry from humansB．set up a central slaughtering house
    C．set up several regional slaughtering housesD．get avian flu vaccination
    小题3:When the final decision will be made mainly depends on ______.
    A．the demand for live chickensB．the views of the public
    C．the advice from experts
    D．the time when regional slaughtering houses will be finished
    小题4:Which of the following statements isn’t Dr York Chow’s opinion?
    A．Hong Kong is better at dealing with viral outbreaks than its neighbours.
    B．Infectious diseases could happen in any country.
    C．Other territories should ask Hong Kong for help because it has more experience.
    D．Cooperation is quite necessary when danger is coming.

    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
