  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之所以打破紀錄是因為它的飛行速度是音速的7倍。它不是第一架空氣噴氣式飛機,也不是第一架超音速飛機,所以A和D都不對。Hyper-X的試飛并未繞赤道飛行,所以B也是錯誤的選擇。  3. A 根據第五段內容,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。
