            2023職稱英語考試理工類的閱讀理解模擬題2

              閱讀下面的短文。每篇短文的后面有五個問題,每個問題有四個備選答案。請根據短文的內容選擇最佳答案。每個試題計3分,共計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.無人的 booster rocket 助推火箭5skrAmdVet5kB:^Eup

              噴氣發動機

              練習:

              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.

              答案與題解:

              2. B 第四段講了三種發動機的氧氣噴氣式發動機是從空氣中汲取氧氣,火箭發動機必須自攜氧氣,而超音速沖壓噴氣發動機則不必白攜氧氣,而這正是Hyper-X使用的發動機裝置。

              4. D 文章的第六段中,密歇根大學的研究人員Werner J.A.Dahm說,Hyper-X的試飛成功只是研制一種新式快速飛機過程中的一個里程碑,而不是新型飛機的誕生。所以,D是正確選擇,A是錯誤選擇。B也不是Werner J.A.Dahm想要表達的意思。C是其他下程師而不是Werner J.A.Dahm說的話。
