閱讀下面的短文。每篇短文的后面有五個(gè)問(wèn)題，每個(gè)問(wèn)題有四個(gè)備選答案。請(qǐng)根據(jù)短文的內(nèi)容選擇最佳答案。每個(gè)試題計(jì)3分,共計(jì)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(wú)人的 booster rocket 助推火箭5skrAmdVet5kB:^Eup
噴氣發(fā)動(dòng)機(jī)
練習(xí)：
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(fā)動(dòng)機(jī)的氧氣噴氣式發(fā)動(dòng)機(jī)是從空氣中汲取氧氣，火箭發(fā)動(dòng)機(jī)必須自攜氧氣，而超音速?zèng)_壓噴氣發(fā)動(dòng)機(jī)則不必白攜氧氣，而這正是Hyper-X使用的發(fā)動(dòng)機(jī)裝置。
4. D 文章的第六段中，密歇根大學(xué)的研究人員Werner J.A.Dahm說(shuō)，Hyper-X的試飛成功只是研制一種新式快速飛機(jī)過(guò)程中的一個(gè)里程碑，而不是新型飛機(jī)的誕生。所以，D是正確選擇，A是錯(cuò)誤選擇。B也不是Werner J.A.Dahm想要表達(dá)的意思。C是其他下程師而不是Werner J.A.Dahm說(shuō)的話。
