2023职称英语考试理工类阅读理解必备训练题

  Flying the Hypert1 Skies

  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.

  The Hyper-X broke the record because

  B it flew along the equator.

  D it traveled at a supersonic speed.

  A A jet engine that gets oxygen from the air.

  C A rocket engine that carries its own supply of oxygen.

   What is NOT true about the scramjet engine?

  B It extracts oxygen from the air that flows through the engine.

  D It doesnt carry its own oxygen supply.

  A It indicated the birth of a very fast airplane.

  C It can transportcargo quickly and cheaply to the brink of space.

  What has NASA planned to do?

  B To make three more Hyper-X experiments.

  D To make the aircraft fly higher and longer.

  C Hyper-X之所以打破纪录是因为它的飞行速度是音速的7倍。它不是第一架空气喷气式飞机,也不是第一架超音速飞机,所以A和D都不对。Hyper-X的试飞并未绕赤道飞行,所以B也是错误的选择。

  A 根据第五段内容,B、C、D都是正确的说法。第四段最后一句告诉我们,A的说法是不正确的。

  A 答案可在最后一段找到。
