Question

    Millions of aircraft take off around the world every year. The skies they fly in seem limitless—miles of empty space. But, with the number of flights increasing each year, this emptiness no longer exists. Researchers in the world of aviation(航空)are worried about the increasing pressure on pilots and ground controllers. And increasing collisions, occurring at or near an airport, have called attention to the need for more aids(辅助设备)to aviation control.

    People who travel the skies are not certain about air safety. A great deal of money is spent on new and bigger air craft and airports to deal with the vast increase in passengers traveling by air. Only a small percentage of this money is spent on navigation(导航)and other aids. Actually, suitable electronic equipment has long existed, and many companies market safety aids designed to make it safer for aircraft to take off, fly any distance, and land, whatever the weather. Yet, there are two problems to be solved. The first is to get governments, airlines and airport officials to agree to basic levels of safety aids. The second problem is to find a way of meeting these basic requirements.

    But no matter how well the equipment works, operators of the equipment still play an important role. Communications between pilots and ground controllers are extremely important to air safety. It is worth pointing out that the mishearing or misunderstanding of instructions in English, and the use of another language, in an international conversation, has led to two recent aircraft accidents. A new type of instrument (仪器) called FLIGHTWATCH would help pilots prevent airport collisions. It would be particularly helpful near airports.

1. The increasing number of flights leads to the fact that _____.

A. flying is no longer limited in the sky

B. there is no empty space for aids to aviation control

C. piloting and controlling planes is getting more difficult

D. the pressure on the ground becomes greater

2. There is uncertainty about air safety because _________.

A. planes become bigger for the increasing number of passengers

B. money spent on electronic equipment is far from enough

C. suitable electronic equipment hasn’t been invented yet

D. it is dangerous for planes to take off or land

3. The underlined word “collisions” probably means _______.

A. accidents in which two planes hit each other

B. misunderstandings between pilots and ground controllers

C. quarrels among passengers

D. breakdowns of new types of instrument

4. It can be inferred from the passage that _______.

A. governments and officials have paid great attention to air safety

B. there should be more companies to sell new safety aids

C. English should be used in an international conversation

D. understanding between pilots and ground controllers should be improved

 

Answer 1

答案：ADBC
解析：

1. 细节判断题。原文第一节中“…But, with the number of flights increasing each year, this emptiness (=miles of empty space) no longer exists. Researchers in the world of aviation are worried about the increasing pressure on pilots and ground controllers.”表明由于每年飞机航班数的增长，航空专家担心由此对飞行员和地面控制人员造成不断增长的压力。可见D项最符合题意。 2. 细节综合分析判断题。根据原文第二节的陈述：“…A great deal of money is spent on new and bigger aircraft and airports to deal with the vast (=large) increase in passengers traveling by air. Only a small percentage of this money is spent on navigation and other aids.”说明大量资金花在了为应付大幅度增长的航空旅客而建造新的更大型的飞机和机场。而只把很少一部分资金用于导航及其辅助设备上。因此，B项是本题惟一的正确答案。 3. 语境词义判断题。根据第一节collisions所在句子的前后语境，即：“Researchers are worried about the increasing pressure on pilots and ground controllers. And increasing collisions, occurring at or near an airport, have called attention to the need for more aids to aviation control.”可以得知，航班的大量增加给飞行员及地勤人员造成很大压力，这就自然导致机场及周边地区不断增长的飞行事故。本题答案A项是最贴切的。 4. 逻辑推理题。根据短文的陈述，A、B项与短文基本内容不符。短文对航空运输的现状作了详细阐述后，在最后一节特别强调飞行员与地勤人员的沟通必须引起重视。应该说，本题选D项在情理之中。
