Today, air travel is far safer than driving a car on a busy motorway. 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 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 167 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. The distance between them was less than that of a large swimming pool. This is an example of the danger that grows every year.
Questions 23 to 25 are based on the passage you have just heard.
23. Which factor can most seriously endanger airplanes according to this passage?
24. What happened to the large jets?
25. Why were the two large jets specially mentioned?
选项
A、They bumped into each other over a swimming pool.
B、They avoided each other by turning in different directions.
C、They narrowly escaped crashing into each other.
D、One plane climbed above the other at the critical moment.
答案
C
解析
D)中的One plane和the other表明,选项中的They指的是two planes。由短文中提到的They avoided eachother…of a second可知,收到空中交通管制员错误指令的两架大型喷气客机最终没有撞到一起,故答案为C)。
