第2题

Tokyo, the capital of Japan, is one of the largest cities in the world. It is also one of

the world's most modern(现代化的)cities. Twice this century, the city was destroyed and rebuilt. In 1923 a major earthquake struck the city. Thousands of people were killed and millions were left homeless as buildings collapsed(倒埸)and fires broke out throughout Tokyo. It took seven years to rebuild the city. During World War Ⅱ ,Tokyo was destroyed once again. As a result of these disasters(灾难), there is nothing of old Tokyo remaining in the downtown area.

After the war, the people of Tokyo began to rebuild their city. Buildings went up at a fantastic(令人惊奇的)rate, and between 1945 and 1960, the city's population more than doubled. Because the Olympic Games held in Tokyo in 1964, many new stadiums(体育场), parks and hotels were built to accommodate(供给……住宿)visitors from all over the world. As a result of this rapid development, however, many problems have arisen (出现). Housing shortage (缺乏), pollution and waste disposal(处理) have presented serious challenges(挑战) to the city, but the government has begun several programs to answer them.

What kind of city is Tokyo？

A．A historic city.

B．A world famous seaport.

C．A highly modernized city.

D．A most attractive city for tourists.

Imagine a world in which children would be the rulers and could decide not only the outcom

e of each and every occurrence, but also dictate the very structure and form. of the environment. In this world, a child's wildest thoughts would become reality, limited only by the extent of his or her imagination. While such a world might sound both fantastic and frightening, at least from a logical, adult perspective, it does exist. What's more, it has been in existence for some time and is populated by hundreds of thousands of children who spend hours within its boundaries experimenting and learning. This world is not real, at least not in the traditional sense, but exists within a computer and is generated by an educational programming language called LOGO. Unlike other computer languages and programs that are designed to test children and provide applications that formally dispense information, LOGO allows children, even preschool children, to be in total control. Children teach the computer to think and as a result develop and sharpen their own reasoning abilities.In the imagined world ______ would restrict children's wildest thoughts.A.the limits of their imaginationB.the structure and form. of the environmentC.the reality of lifeD.the roles of the society

Millions of words have been written about young people in the United States. There are rea

sons for this great interest in the ideas, feelings, and actions of youth.

Today there are about seven million Americans in the colleges and universities. Young persons under twenty-five make up nearly half of the American population. Many of these will soon be in charge of the nation. Naturally, their ideas are important to everyone in the country, and it is necessary for older people to understand what they think and feel.

College students today have strong opinions about right and wrong. They are deeply interested in making a better life for all people, especially for those who have not been given a fair chance before now. They see much that is wrong in the lives of their parents. It is hard for them to see what is right and good in the older ways. As a result, there is often trouble in American families.

Which of the following statements is true？

A．People haven' t written much about American youth.

B．Writers have wasted a great deal of their effort to write about American youth.

C．Much has been written about American youth.

D．Young people' s ideas are not important enough to the USA.

Could HIV, the virus that causes AIDS, be weakening？ The results of a study conducted in Belgium, at the Institute of Tropical Medicine in Antwerp, seem to suggest that in one corner of the world it might be. The report, published in the latest issue of AIDS, a specialist journal, concludes that HIV's ability to replicate (known technically as its virulence) may have decreased since the start of the pandemic. Kevin Aden, the lead author of the paper, stresses that the study is based on a small set of samples and does not prove that HIV's virulence is attenuating around the world. However, it does offer new insights into the evolution of the disease.

Dr. Arien looked at 24 blood samples collected from untreated patients attending an HIV/ AIDS clinic in Antwerp. A dozen of these samples were taken between 1986 and 1989; the other 12 were collected between 2002 and 2003. First, he analyzed the samples to find their viral load (the number of virus particles per cubic centimeter) and the subtype of virus involved. In Europe and North America, the predominant subtype is B; in sub-Saharan Africa, where the epidemic is at its worst, the predominant subtype is C. Most of Dr. Arien's samples were of subtype B. Having done this analysis, he paired the samples off for a series of replicative "duels". Each sample from the earlier series was matched with the most similar one from the later series, and they were placed in identical cell cultures to see which would multiply the most. The result was that 75% of the viruses from 2002-03 were less virulent than apparently similar counterparts from 1986-89—a statistically significant observation.

Dr. Arien's caution is sensible, at least until someone replicates the work elsewhere. But his conclusion is not necessarily surprising. Such viral attenuation, as it is known, is one way that vaccines are produced.

What causes attenuation in wild viruses, though, is a matter of speculation. Dr Arien believes that in this case the attenuation could be the result of what he calls "serial genetic bottlenecks" during transmission from host to host. These act to reduce the genetic diversity (and thus the replicative fitness) of the virus. Genetic diversity is known to be an important component of HIV's virulence. But what might cause the bottlenecks is still unclear.

A second reason for caution besides the small size of the study is, as Geoffrey Garnett, a professor of microparasite epidemiology at Imperial College, London, points out, that the ability of a virus to infect cells in a test-tube is not the same as its ability to cause disease and death in a human host. Nevertheless, Dr Aden's result is intriguing, and surely worth following up in a larger piece of research.

The word "attenuating"(Paragraph 1) most probably means

A．weakening.

B．accentuating.

C．accelerating.

D．increasing.

Born in 1830 in rural Amherst, Massachusetts, Emily Dickinson spent her entire life in the

household of her parents. Between 1858 and 1862, it was later discovered, she wrote like a person possessed, often producing a poem a day. It was also during this period that her life was transformed into the myth of Amherst. Withdrawing more and more, keeping to her room, sometimes even refusing to see visitors who called, she began to dress only in white -- a habit that added to her reputation as an eccentric.

In their determination to read Dickinson's life in terms of a traditional romantic plot, biographers have missed the unique pattern of her life -- her struggle to create a female life not yet imagined by the culture in which she lived. Dickinson was not the innocent, lovelorn and emotionally fragile girl sentimentalized by the Dickinson myth and popularized by William Luce's 1976 play, the Belle of Amherst. Her decision to shut the door on Amherst society in the 1850's transformed her house into a kind of magical realm in which she was free to engage her poetic genius. Her seclusion was not the result of a failed love affair, but rather a part of a more general pattern of renunciation through which she, in her quest for self sovereignty, carried on an argument with the puritan fathers, attacking with wit and irony their cheerless Calvinist doctrine, their stem patriarchal God, and their rigid notions of "true womanhood."

What's the author's main purpose in the passage？

A．To interpret Emily Dickinson's eccentric behavior

B．To promote the popular myth of Emily Dickinson

C．To discuss Emily Dickinson's failed love affair

D．To describe the religious climate in Emily Dickinson's time

We first think of the traditional or nuclear family. This is a two-generation family, the

father and the mother and their own children. Most couples wanted to have four children, two boys, two girls.

Some nuclear families, however, may add one or more grandparents to come to live with them, that is three generations. This kind of family with grandparents, parents, and grandchildren is called an extended family. This family type was not very common during the later half of the twentieth century, but it's becoming more common now as an elderly grandparent moves in to live with a son or daughter. This is more possible now that American homes have become larger. What is interesting, however, is that after the grandchildren move out of the home and start their own families, this extended family shrinks back to a nuclear family, with just two generations again living together, a grandparent and parents, with the grandchildren coming only for occasional visits.

Now, the fatherless or motherless family is one kind of what we call a single-parent family. In the fatherless family it's just the mother and her children. As I said, this can be the result of the husband's death, of an unmarried mother, of a separation or divorce. There are also a growing number of motherless families--where the father raises the children, for any of the same reasons. A motherless family may also be fatherless, but still a family with one adult. This is becoming more common in the big cities where a grandmother will raise her daughter's children while the daughter goes elsewhere to work.

One other new kind of family is becoming increasingly more common. A single parent with one or more children will marry again. Perhaps the other parent is also a single parent. Together they will start what is called a blended family, which blends together or combines the children from two other families.

An extended family usually has ______.

A．two generations

B．three generations

C．four generations

D．one generation

Passage Two

In 2000, with little but a bar and a church left to make it a destination, tiny St. James, Nebraska, was taken off state highway maps. Then the church closed, and the small farm village in the state’s northeast corner looked set to just disappear. Thanks to five devoted women, it didn’t.

In May 2001, after meeting with staff from the Center for Rural Affairs, the friends—Louis Guy, Vicky Koch, Jeanette Pinkelman, Mary Rose Pinkelman and Violet Pinkelman—opened a weekend market for vendors(小商贩) to sell handcrafts and local food.

“We felt like, what can we do to bring the community together？” says Mary Rose Pinkelman, “We decided to make a place to sell local goods.” They set up shop in the church school, which, though closed for nearly 40 years, had been well maintained. The first weekend, 16 vendors look over an old classroom. The result was an instant hit. Today, the market draws up to 70 vendors----who sell such items as homemade jellies, baked goods, hand-woven rugs, and farm-grown produce----and what Pinkelman calls an unexpected number of visitors. In the process, the market has made St. James a destination again, putting it back on the state road map.

40. According to Para. 1, what fate was St. James Nebraska suffering？

A The replacement of the church school

B The disappearance from highway maps

C The closedown of the bar

D The set-up of a market
