【小题1】But still there is a danger that grows every yearAirliners get larger．Some airplanes

【小题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．【小题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．【小题3】． Recently such a disaster almost happened． 【小题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．【小题5】． A．Even a small mistake on their part could cause a disaster．B．Two large jets were flying towards the airportC．Nowadays people like traveling more by air than by carD．Today air travel is far safer than driving a car on a bus motor-wayE． 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 screenD

(答案→)D 解析：【小题1】后文讲到But still there is a danger that grows every year仍然存在危险，而且每年都在上升，前后意思应该是相对立的，故选D【小题2】后文讲到Air traffic controllers tell the pilot exactly when to turn when to climb and when to come down．航空管理员精确地告知飞机何时爬升何时下降，故选G，飞机都会在雷达上进行显示。【小题3】根据后文Recently such a disaster almost happened．讲到了这样的灾难差点就发生了，故选A【小题4】根据后文One with 69 passengers had come from Toronto and the other with 176 passengers from Chicago ,讲到两辆飞机朝着机场飞行的情况，故选B【小题5】前文讲到The distance between them was less than that of a large swimming pool．它们之间的距离仅仅只有一个游泳池那么大的距离，所以灾难差点发生，故选E

这个问题我还想问问老师呢
