IV. Reading Comprehension (60 points)
Directions: There are five reading passages in this part. Each passage is followed by four questions. For each question there are four suggested answers marked A, B, C and D. Choose one best answer and blacken the corresponding letter on the Answer Sheet.
Passage One
Wild and farm birds often get a flu virus. Yet they usually are able to carry the virus without getting sick.
In 1997 six people in Hong Kong died of a different kind of bird flu virus. It is called the h-five-n-one virus. The Hong Kong government quickly ordered the killing of all farm birds there. That stopped the spread of h-five-n-one to people in Hong Kong.
Yet the virus bad already spread to other parts of Asia. It was found in 16 countries between 2003 and 2006.
The h-five-n-one virus first appeared in Africa. This raised many concerns about the spread of the disease. Scientists do not know exactly how bird flu came to Africa. At first, they thought wild birds were to blame. Now, officials with the U. N. Food and Agriculture Organization believe the main cause is trade in farm birds.
The bird flu virus is found in the waste and liquids of infected birds. The virus spreads when healthy birds or people touch sick birds or nay infected (被感染了的) part of sick birds. Right now, the virus is not spreading among person to person. But the virus could change and start spreading among people. Health officials believe that it is even more possible now that bird flu has spread in Africa, and that is why international organizations are working so hard to stop its spread.
The best way to stop the spread of bird flu is to kill all the chickens in an area where bird flu has been discovered. More than 145 000 chickens have been killed in Nigeria since bird fin was first found one year ago.
36. The passage focuses on ______.
A. wild and farm birds
B. a fin virus
C. bird flu
D. infected birds
Societies differ in how they structure marriage relationships. Four patterns are found: monogamy, one husband and one wife are found; polygyny, one husband and two or more wives; polyandry, two or more husbands and one wife; and group marriage, two or more husbands and two or more wives. Although monogamy exists in all societies, Murdock discovered that other forms may be not only allowed but preferred. Of 238 societies in this sample, only about one-fifth were strictly monogamous.
Polygyny has been widely practiced throughout the world. The Old Testament reports that both King David and King Solomon had several wives. In his cross-cultural sample of 238 societies, Murdock found that 193 of them permitted husbands to take several wives. In one-third of these polygynous societies, however, less than one-fifth of the married men had more than one wife. Usually it is only the rich men in a society who can afford to support more than one family.
In contrast with polygyny, polyandry is rare among the world's societies. And in practice, polyandry has not usually allowed freedom of mate selection for women; it has often meant simply that younger brothers have sexual access to the wife of an older brother. Thus where a father is unable to afford wives for each of his sons, he may secure a wife for only his oldest son.

Apart from choosing a partner for life and hopefully having a family of ones own,perhaps the most important decision that one takes in life concerns the choice of a career.It is a good idea if young people realise that there is a big difference between a career and ajob. A job can mean anything from doing the washing up in a restaurant during the univer-sity vacation to working ina corner shop. It may be that a particular job lasts for years,but unless it involves some aspect of special training leading to qualifications, it remains a job and not a career, There are of. course. exceptions to this generalisation For example.many pop singers are self-trained, but the suecessful ones think of their development astheir career.
Of course. it has to be said that certain careers require fairly low level qualifications before a person can enter a training programme or gain experience on the job, In Britain,being a policeman or a nurse only requires a person to have the basic school leaving certificate of four or five GCSEs. Unfortunately, with the same kind of qualifications, a police -man can earn a quite reasonable salary, while,ordinary nurses are among the worst paid professionals of that society. Of course, certain careers take years of training for example, if one wants to become an accountant,a doctor or a lawyer. Even senior teachers, particularly those working in universities. may be in full-time educational training for eight years.
It is essential that young people choose their career carefully. It is no good wanting to he a doctor if one cannot stand the sighi of blood! It is pointless considering the teaching profession if one doctors not like young people. Some people even have the most peruliar And unrealistic ideas of what they want to do. Take for example the case of a young man who rang up a radio programme about careers recently and said he wanted advice on how to become a lion tamer! It is very likely that lion tamers (and there are not that many around) start working with animals at a very early age. They are probably born into a show business family. The young man on the radio, on the other hand, did not even seem to like cats.
What other two choices are important in life apart from a career?
A.Choosing a partner for life and doing the washing up in a restaurant.
B.Choosing a partner for life and working in a corner shop.
C.Choosing a partner for life and hopefully havinK a family of one’s own.
D.Taking a job and having a family of one’s own.

D.A detailed statement.
What does it require in Britain to be b policeman or a nurse?A.A training programme

It is not customary to telephone someone very early in the morning in the USA. If someone is called very early in the morning,while he is shaving or having breakfast,the time of the call indicates great importance of the matter which requires immediate attention of the person called. The same implication is attached to telephone calls made after 11:00 p.m. at night. If someone receives a call during sleeping hours,he assumes it’s an urgency of life or death. The time chosen for the call communicates its importance. Time plays a very important role in our social life as you can imagine. In the USA an invitation should be sent to the guests in advance because guests usually believe that they are not highly regarded if the invitation to a dinner party is extended only three or four days before the party date. But it is not always necessarily true of the case all over the world. In some other countries,it may be taken stupid to make an appointment too far in advance because plans made for a date more than a week away tend to be forgotten. The concept of time varies in different regions of the world. Thus,misunderstandings are sometimes inevitable between men of different cultural backgrounds that treat time differently. Promptness is valued highly in America,for example. A lack of promptness is regarded as being impolite or not being fully responsible. In the US it would be incredible to keep a business partner or a guest waiting for an hour,and it would be too impolite and unacceptable by their social etiquettes. A person who is 5 minutes late is expected to give some words of explanation to the people waiting,though he might not complete his sentence.

Steel has given that 20-hour figure when describing her“exhausting”process in the past:“I start thebook and don 't leave my desk until the first draft is finished.”She goes from bed,to desk,to bath,tobed,avoiding all contact aside from phone calls with her nine children."I don 't comb my hair for weeks,”she says.Meals are brought to her desk,where she types until her fingers swell and her nails bleed.The business news website Quartz held Steel up as an inspiration,writing that if only we all followedher“actually extremely liberating"example of industrious sleeplessness,we would be quick to see results.well,indeed.With research results showing the cumulative effects of sleep loss and its impact onproductivity,doubt has been voiced about the accuracy of Steel's self-assessment.Her output may beundeniable,but sceptics have suggested that she is guilty of erasing the role of ghostwriters (代笔人) atworst,gross exaggeration at best.
Steel says working 20 hours a day is “pretty brutal physically.”But is it even possible?“No,”saysMaryanne Taylor of the Sleep Works. While you could work that long,the impact on productivity wouldmake it hardly worthwhile. If Steel was routinely sleeping for four hours a night,she would be drasticallyunderestimating the negative impact,says Alison Gardiner,founder of the sleep improvement programmeSleepstation.“It's akin to being drunk.”
lt's possible that Steel is exaggerating the demands of her schedule. Self-imposed sleeplessness has“become a bit of a status symbol", says Taylor, a misguided measure to prove how powerful and productive you are.Margaret Thatcher was also said to get by on four hours a night,while the 130-hour work weeksendured by tech heads has been held up as key to their success.
That is starting to change with increased awareness of the importance of sleep for mental health.“People are starting to realise that sleep should not be something that you fit in between everything else,"says Taylor .
But it is possible—if statistically extremely unlikely—that Steel could be born a “short sleeper”withan unusual body clock,says sleep expert Dr. Sophie Bostock." It's probably present in fewer than 1% ofthe population.”
Even if Steel does happen to be among that tiny minority,says Bostock,it's “pretty irresponsible”tosuggest that 20-hour days are simply a question of discipline for the rest of us.
