A farewell party was going on. Sylvia Calver hated being the center of any pubic show where she didn’t know anyone. It made her 36  hot and she always felt she wanted to go away somewhere. But on an occasion like this when she knew 37 , there was no 38 to feel shy. 39she had made up her mind to 40  people’s attention for once in her life. Unlike others, Sylvia didn’t have any sad feelings herself at leaving Palmeira Court Hotel or saying goodbye to its 41  — she had left so many other 42 , and known too many people in her life to get upset by such things now.

Yet this 43 was a particular occasion, and she hadn’t had so many of those in her 44. She had put on her 45  black dress and her long earrings. She had wanted to enjoy being the center of 46 for one evening, but now they had 47  old Miss Hutton of all people to give the 48 speech, whom she disliked. Even so, she thought there was no sense in getting 49  about it, for it was the first rule her 50 had given her — avoid all anxiety, take things easy. So, surprising herself by enjoying her own well-rounded white arm as 51 showed through the sleeve of her 52  dress, she took a taste of her drink and then sat back comfortably with her cigarette. And her doctor’s orders worked! For 53  out slowly, she put Miss Hutton off the end of her 54  with a cloud of tobacco smoke, so that she smiled to herself at the old girl’s funny expression. She 55 herself quite well that night, even to her own surprise.

What is intelligence anyway? When I was in the army I   21        an intelligence test that all soldiers took, and, against an average of 100, scored 160.

Dear Mr. Takashhi,

I am writing to apologize for any misunderstandings that occurred when I showed you around Beijing the other day. I noticed that you were a bit 31 when I put the business card you gave me in my 32 without looking at it. And 33 did not know why you kept making an OK sign and why you 34 so many things. After reading a magazine article, I know that Japanese people give out their business cards 35 they greet others and they would like others to look at their cards carefully. So I should have read your 36 before I put it in my pocket. And I also know why you bought so many things 37 . Because gift-giving is expected in Japan and on a trip, you must bring back lots of 38 . As for the OK sign, I now know it is a request for small change.

第三部分： 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）

阅读下面短文，掌握其大意，然后从41~55各题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题卷上将该项涂黑。

(A)

In 1901, H.G. Wells, an English writer, wrote a book describing a trip to the moon. When the explorers landed on the moon, they discovered that the moon was full of underground cities. They expressed their surprise to the “moon people” they met. In turn, the “moon people” expressed their surprise. “Why,” they asked, “are you traveling to outer space when you don’t even use your inner space?”

H.G. Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon. People today know that there are no underground cities on the moon. However, the question that the “moon people” asked is still an interesting one. A growing number of scientists are seriously thinking about it.

Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Chunnel”, a tunnel connecting England and France, is now complete.

But what about underground cities? Japan’s Taisei Corporation is designing a network of underground systems, called “Alice Cities”. The designers imagine using surface space for public parks and using underground space for flats, offices, shopping, and so on. A solar dome (太阳能穹顶) would cover the whole city.

Supporters of underground development say that building down rather than building up is a good way to use the earth’s space. The surface, they say, can be used for farms, parks, gardens, and wilderness. H.G. Wells’ “moon people” would agree. Would you?

1. The explorers in H. G. Wells’ story were surprised to find that the“moon people” ___________.

A. knew so much about the earth            B. understood their language

C. lived in so many underground cities    D. were ahead of them in space technology

2. What does the underlined word “it” (Paragraph 2) refer to?

A. Discovering the moon’s inner space.               B. Using the earth’s inner space.

C. Meeting the“moon people”again.                         D. Traveling to outer space.

3. What sort of underground systems are already here with us?

A. Offices, shopping areas, power stations.

B. Tunnels, car parks, shopping areas.

C. Gardens, car parks, power stations.

D. Tunnels, gardens, offices.

4. The word “wilderness” in the last paragraph means___________.

A. wildlife                                                                  B. poor districts

C. desert                                                         D. an area that is not allowed to build on

5. What would be the best title for the text?

A. Alice Cities — cities of the future

B. Space travel with H. G. Wells

C. Enjoy living underground

D. Building down, not up
