Today, air travel is far safer than driving a car on a busy motor way. But there is the danger that grows every year. From the moment the airplane takes off to the moment it lands, every moment is watched on radar screens. Air traffic controllers tell the pilot exactly when to turn, when to climb and when to come down. The traffic controllers around the busy airport may handle 1,000 planes a day. Any plane that flies near the airport comes under the orders of the controllers there. Every small mistake on their part could cause a disaster. Recently, such a disaster almost happened. Two large jets were flying towards the airport. One was carrying 69 passengers and had come from. Toronto, the other was carrying 176 passengers from Chicago. An air traffic controller noticed on his radar screen that the two planes were too close to each other. He ordered one to turn to the right to climb, but he made a mistake. He ordered the wrong plane to do this. So, instead of turning away from the second plane, the first plane turned towards it. 15 seconds later, it flew directly in front of the second plane. They avoided each other by a second. The distance between them was less than that of a large swimming pool. This is an example of the danger that grows every year.
选项
A、To show that air travel is far safer than driving a car.
B、To show the great responsibility shouldered by the pilots.
C、To give an example of air disasters.
D、To show the key role played by air traffic controllers.
答案
D
解析
该题问“为什么特别提到这两架大飞机?”从这个例子前面的一句"Ever a small mistake on their part could cause a disaster."(他们的一个小小的失误都会带来一场灾难。)和例子后面的一句"This is an example of the danger that grows every year."(这是一个每年都在增长的危险的例子。)可以知道这个例子是为了说明空中管制员的责任大小,一个细微的错误就可能导致大祸。故[D]“为了说明空中管制员的关键责任”正确
