Ⅲ.阅读理解(共15题,每小题2分,满分30分)

(A)

Audrey Hepburn was born on May 4, 1929 in Brussels, Belgium. Her father was a wealthy English banker. After her parents divorced, Audrey went to London with her mother where she went to a private girl school. While vacationing with her mother in Holland, Hitler’s army suddenly took over the town. It was here that she fell on hard times during the Nazi occupation. After the liberation, Audrey went to a ballet school in London on a scholarship and later began a modeling career. As a model, she was graceful and, it seemed, she had found her niche(位置) in life—until the film producers came calling. After being spotted modeling by a producer, she was signed up to a bit part in the European film Nederlands in 7 lessons in 1948. Later, she headed to America to try her luck there.

Audrey gained immediate prominence in the US with her role in Roman Holiday in 1953. This film turned out to be a big success as she won an Oscar as Best Actress. This gained her enormous popularity and more plum roles. Roman Holiday was followed by another similarly wonderful performance in the 1957 Classic Funny Face(1957). In 1959, she received yet another nomination(提名) for her role in Nun’s Story. Audrey reached the top of her career when she played Holly Golightly in the film Breakfast at Tiffany’s in 1961. For this she received another nomination. One of Audrey’s most radiant(辉煌的) roles was in the fine production of My Fair Lady in 1964. Her co-star Rex Harrison once was asked to identify his favorite leading lady. Without hesitation, he replied, “Audrey Hepburn in My Fair Lady”.

By the end of the sixties, after her divorce from actor Mel Ferrer, Audrey decided to retire while she was on top. Later she married Dr. Andrea Dotti. In 1988, Audrey became a special ambassador to the UNICEF helping children in Latin America and Africa, a position she retained until 1993. She was named to People’s magazine as one of the 50 most beautiful people in the world. Audrey Hepburn died on January 20, 1993 in Switzerland. She had made a total of 31 high-quality movies.

1. Where did Audrey Hepburn become famous? ____.

A. EnglandB. AmericaC. SwitzerlandD. Belgium

2. We can infer that Audrey Hepburn was ____.

A. a learned womanB. satisfied with her marriage

C. a woman with sympathyD. very popular as a model

3. Which is the right order about the life of Audrey Hepburn? ____.

a. Audrey began a modeling career.

b. Audrey went to London with her mother.

c. Audrey became popular in the film Roman Holiday.

d. Audrey became a special ambassador to the UNICEF.

e. Hitler’s army suddenly took over the town.

f. Audrey married Dr. Andrea Dotti.

A. a, b, c, d, e, fB. b, e, a, c, f, d

C. c, a, b, f, e, dD. b, e, f, c, a, d

4. The underlined word “spotted” can be replaced by ____.

A. seenB. shotC. coveredD. dropped

(B)

In 1901, H.G.Wells, an English writer, wrote a book describing a trip to the moon. When the explorers (探险者) 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 travelling 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 didland 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 “Channel”, a tunnel(隧道) 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
