Today, air travel is far safer than driving a car on a busy motor way. But there is a danger that grows every year.
From the moment an airplane takes off to the moment it lands, every movement is watched on radar screens. Air-traffic controllers tell the pilot exactly when to turn, when to climb and when to come down. The air-traffic controllers around a busy airport may handle 1,000 planes a day. Any plane that flies near the airport comes under the orders of the controllers there. Even a small mistake on their part could cause 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 76 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 and 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. Fifteen seconds later, it flew directly in front of the second plane. They avoided each other by the smallest part of a second. 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 the key role played by air traffic controllers.
B、To show the great responsibility shouldered by the pilots.
C、To give an example of air disasters.
D、To show that air travel is far safer than driving a car.
答案
A
解析
综合理解题。本题的答案虽然并未在短文中直接提供,但是讲话者举出两架飞机的例子是在他提出“飞行调度员即使出现一点儿小差错也可能导致空难发生”这一看法之后,显然是以此作为其观点的论据,所以正确答案选A。
