Question

【題目】根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

【1】 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. 【2】 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． 【3】 Recently such a disaster almost happened． 【4】 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. 【5】

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】

【1】D

【2】G

【3】A

【4】B

【5】E

【解析】

試題分析：本文講述飛機安全。

【1】D 空后說的是“但是每年仍然有不斷增加的危險。”以及根據(jù)后面講飛機飛行，故可知這里首先提出“現(xiàn)在坐飛機比開車旅行安全”，然后又轉(zhuǎn)折，坐飛機的危險依然在不斷增長。故這里選D。

【2】G 后一句說的是：空中交通控制準確的告訴飛行員何時轉(zhuǎn)彎何時上升何時下降。飛機從起飛到降落，都在雷達上被監(jiān)控。后文繼續(xù)寫空中控制的重要性。故這里選G（飛機從起飛到落地，每一刻都被雷達監(jiān)視。）正確。

【3】A 空后句意：最近這樣的災難差點發(fā)生。所以這里A（每個小的失誤都會導致災難的發(fā)生。）符合語境。

【4】B 空后句意：一架有69個乘客的飛機來自多倫多，另一架有176個乘客的飛機來自芝加哥。列舉例子，兩架飛機要在一個機場降落。所以這里B（兩架飛機都向機場方向飛行。）符合語境。

【5】E 上面整個段落都是日益增長的風險的一個例子。故這里E（這是每年日益增長的風險的一個例子。）符合語境。
