  阅读下面的短文。每篇短文的后面有五个问题,每个问题有四个备选答案。请根据短文的内容选择最佳答案。每个试题计3分,共计15分。

  A little airplane has given new meaning to the term going hyper.

  The Hyper-X is an unmanned,experimental aircraft just 12 feet long. It achieves hypersonic speed using a special sort of engine known as a scramjet3.It may sound like something from a comic book,but engineers have been experimenting with scramjets since the 1960s.

  Out of the three experimental Hyper-X aircrafts built for NASA5,only one is now left.The agency has plans for another 11-second hypersonic flight,this time at 10 times the speed of the sound.

  hypersonicadj.超音速的   boostern.助推器

  unmannedadj.无人的 booster rocket 助推火箭5skrAmdVet5kB:^Eup

  喷气发动机

  练习:

  A it was the first air-breathing jet plane.

  C it flew at speeds smaller than five times the speed of sound.

  2. What kind of an engine did the Hyper-X use?

  B A scramjet engine that doesnt carry its own oxygen supply.

  D A iet engine that uses no oxygen.

  A It goes slower than a rocket.

  C It works only at speeds greater than five times the speed of sound.

  4. What did Werner J.A.Dahm of the University of Michigan say about the Hyper-X test flight?

  B It was self-powered,so it lasted only 11 seconds.

  D It is a major milestone in the journey of making a new type of very fast airplanes,

  A To make another 11-second hypersonic flight at 10 times the speed of the sound.

  C To retest the aircraft that is left.

  答案与题解:

  2. B 第四段讲了三种发动机的氧气喷气式发动机是从空气中汲取氧气,火箭发动机必须自携氧气,而超音速冲压喷气发动机则不必白携氧气,而这正是Hyper-X使用的发动机装置。

  4. D 文章的第六段中,密歇根大学的研究人员Werner J.A.Dahm说,Hyper-X的试飞成功只是研制一种新式快速飞机过程中的一个里程碑,而不是新型飞机的诞生。所以,D是正确选择,A是错误选择。B也不是Werner J.A.Dahm想要表达的意思。C是其他下程师而不是Werner J.A.Dahm说的话。
