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. 1. 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. 3. 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. 5. What has NASA planned to do? B To make three more Hyper-X experiments. D To make the aircraft fly higher and longer. 1. C Hyper-X之所以打破紀(jì)錄是因?yàn)樗娘w行速度是音速的7倍。它不是第一架空氣噴氣式飛機(jī)，也不是第一架超音速飛機(jī)，所以A和D都不對(duì)。Hyper-X的試飛并未繞赤道飛行，所以B也是錯(cuò)誤的選擇。 3. A 根據(jù)第五段內(nèi)容，B、C、D都是正確的說法。第四段最后一句告訴我們，A的說法是不正確的。 5. A 答案可在最后一段找到。
