4(典型例题Ⅱ C)

It's not the flashiest car in the world. Not even close. But the 1971 Volkswagen named Helios can do something most cars can't: nm on solar energy--energy from the sun's light and heat !　　　　

Joshua Bechtold, 14. and the other students at the Riverside School in Lyndonville, Vermont, worked many months to get Helios ready for the 1999 American Tour de Sol("Sol" is the Latin word for "sun"). They named their car after Helios, the sun god in Greek mythology(神话) .

　　　 The 4-year-old Tour de SOl encourages the use of "green", or environmentally friendly, cars to help reduce pollution and save energy. It's not a race. Cars are judged on fuel efficiency (耗油量) rather than speed. In the week-long event, 44 cars took the 350-mile tour from Waterbury, Connecticut, to Lake George, New York. Of the 23 student cars, Helios was the on- ly one built by middle school students.

　　　 A teacher drove Helios, but the children talked with people wherever they stopped along the road "That was my favor- ite part. "says Anna Browne, 15. "We explained how the car runs."

　　　 Due in part to old, inefficient batteries (电池), Helios finished　 fourth out of four　　 in its kind, the sun-powered class. "We were 　there for the fun of it. "Anna says. "We're proud of Helios, ' says　 Ariel Gleicher, 14. "It's a car that's good for the environment."

3. The underlined word "land" in the last paragraph probably means______.

　 A. keep for some time

　 B. successfully get

　 C. immediately start

　 D. lose regretfully

答案: B　 指导：这是一道猜义题。根据land后的宾语the first job 可判断出它的意思是“成功地获得”。

2. Compared with graduates of other subjects, social science graduates______.

　　 A. are ready to change when situations change

　　 B. are better able to deal with difficulties

　　 C. are equally good at computer skills

　　 D. are likely to give others pressure

答案: A　 指导：这是一道细节推断题。根据第二段中“Studies 　show that social science maiors are．．”可判断出与其他专业的毕业生相比，社会科学的毕业生在形势改变时，他们更乐意改变。

1. By saying that" you may have had the last laugh" in the first　 paragraph, the author means that you　 may have______.

　 A. shared the jokes with computer majors　

　　 B. earned as much as computer majors

　　 C. found jobs more easily than computer majors　

　　 D. stopped joking about computer majors

答案: C　 指导：这是一道推断作者意图题。从第一段"Thereare many advantages for the social science major．．．”可知，灵活和好的交际技巧在“信息社会中”是十分重要的，所以学习社会科学的毕业生比学习计算机的毕业生可能更容易找到工作。

4. What can we infer from the last three paragraphs?

　A. Most of us could be good at sports even at 120.

　 B. The average human life span cannot be doubled.

　 C. Scientists believe mice are aging at a slower speed than before.

　 D. New techniques could be used to change flies into a new　 species. Passage

答案: B　 指导：根据后三段的内容可推断出人们的平均寿命不会加倍。

　　 If you are a recent social science graduate who has had to listen to jokes about unemployment from your computer major classmates, you may have had the last laugh. There are many advantages for the social science major because this high-tech "Information Age" demands people who are {lexible(灵活) and who have good communication skills.

　　 There are many social science majors in large companies who fill important positions. For example, a number of re- search studies found that social science majors bad achieved greater managerial success than those how had technical train- lng or pre-professional courses; Studies show that social science majors are most suited for change, which is the leading featured (特点) of the kind of high-speed, high-pressure, high-tech world we now live in.

　　　 Social science majors are not only experiencing success in their long term company jobs, but they are also finding jobs more easily. A study showed that many companies had filled a large percentage of their entry level positions with social science graduates. The study also showed that the most sought-after quality in a person who was looking for a job was communica- tion skills, noted as "very important" by 92 percent of the companies. Social science majors have these skills, of ten without knowing how important they are. It is probably due to these skills that they have been offered a wide variety of positions.

Finally, although some social science majors may still find it more difficult than their technically trained classmates to land the first job, recent graduates report that they don't regret their choice of study.

3. Who would agree that a scientist will become famous if he makes the wildest guess at longevity?

　A. Jerry Shay.

　 B. Steve Austad.

　 C. Rich Miller.

　 D. George Martin.

答案: C指导：第五段"Anyone can make up anumber，”says Rich Miller at the University Of Michigan。“Usually the scientist who picks the highest number gest his nalne in Time magazine．”说明RichMiller认为对人类的寿命估计最高的科学家会出名。

2. According to Steve Austad at the University of Texas,_________.

　　 A. the average human life span could be 110

　　 B. scientists cannot find ways to slow aging

　　 C. few people can expect to live to over 150

　　 D. researchers are not sure how long people can live

答案: D　 指导：根据第四段Steve Austad的论述可判断出研究人员不能确定人们的寿命有多长。
