Passage Three

Have you ever traveled on any of the giant jet airplanes? If you have not been a passenger on one of these planes, try to imagine a jet which is more than 70 meters long and more than 5 stories high at the tail. [32]Such a plane costs at least 25 million dollars to build. It costs at least $6,000 to fill this giant with fuel. [33]Inside, the jet looks more like a great theatre than a plane. It has 6 kitchens. They are all needed when the plane is full. The jet can hold more than 400 passengers. Imagine that number in one jet plane. Is there any danger that the jet's engines will fail? Fortunately, the planes appear to be quite safe. On each plane, there are twice as many engines as it needs. [34]If two engines fail on the same side, the plane can easily use its other engines to land. [35]There are also two mechanical pilots to take charge, if the human pilots cannot fly the plane.

Questions 32 to 35 are based on the passage you have just heard.

32. How much does it cost to build the giant jet?

正确答案：B

解析：短文说：“制造这种飞机至少要花费2502万美元。”故答案为B。

33. What does the giant jet look like inside?

正确答案：C

解析：短文提到：“这种大型喷气式飞机的内部看上去更像一个大剧院。”故C正确。

34. What do we learn about the engines of the giant jet plane?

正确答案：A

解析：短文提到：“即使同侧有两台发动机失灵，飞机还是可以轻而易举地凭借其他发动机着陆。”故A正确。

35. What will happen if the human pilot cannot fly the plane?

正确答案：A

解析：短文最后一句说：“如果驾驶员不能操纵飞机，两个机械驾驶员就会接替他们的工作。”故选A。
