Question

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。 But still there is a danger that grows every year．Airliners get larger. Some airplanes can hold over 300 passengers. And the air itself becomes more and more crowded. If one giant airliner crashed into another in mid-air 600 lives could be lost. 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 like London-Heathrow may handle 2500 planes a day．Not all of them actually land at the airport．Many plane that flies near the airport comes under the orders of the controllers there. Recently such a disaster almost happened. One with 69 passengers had come from Toronto and the other with 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 and to climb. But he made a mistake. He ordered the wrong plane to do this. 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.
A. Even a small mistake on their part could cause a disaster.
B. Two large jets were flying towards the airport.
C. Nowadays people like traveling more by air than by car.
D. Today air travel is far safer than driving a car on a bus motor-way.
E. This is an example of the danger that grows every year.
F. In a word air travel is more dangerous we should choose others.
G. From the moment an airliner takes off to the moment it lands, every movement is watched on radar screen.

Answer 1

【答案】D；G；A；B；E
【解析】本文讲述飞机安全。

① 空后说的是"但是每年仍然有不断增加的危险。"以及根据后面讲飞机飞行，故可知这里首先提出"现在坐飞机比开车旅行安全"，然后又转折，坐飞机的危险依然在不断增长。故这里选D。

② 后一句说的是：空中交通控制准确的告诉飞行员何时转弯何时上升何时下降。飞机从起飞到降落，都在雷达上被监控。后文继续写空中控制的重要性。故这里选G（飞机从起飞到落地，每一刻都被雷达监视。）正确。

③ 空后句意：最近这样的灾难差点发生。所以这里A（每个小的失误都会导致灾难的发生。）符合语境。

④ 空后句意：一架有69个乘客的飞机来自多伦多，另一架有176个乘客的飞机来自芝加哥。列举例子，两架飞机要在一个机场降落。所以这里B（两架飞机都向机场方向飞行。）符合语境。

⑤ 上面整个段落都是日益增长的风险的一个例子。故这里E（这是每年日益增长的风险的一个例子。）符合语境。
