推荐文章
Millions of aircraft takeoff around the world every year. The skies they fly in seem limitless—miles ofempty space. But, with the number of flights increasing each year, thisemptiness no longer exists. Researchers in the world of aviation(航空)are worried about the increasing pressure on pilotsand ground controllers. And increasing collisions, occurring at or near anairport, have called attention to the need for more aids(辅助设备)to aviation control.
People who travel the skiesare not certain about air safety. A great deal of money is spent on new andbigger air craft and airports to deal with the vast increase in passengerstraveling by air. Only a small percentage of this money is spent on navigation(导航)and other aids. Actually, suitable electronicequipment has long existed, and many companies market safety aids designed tomake it safer for aircraft to take off, fly any distance, and land, whateverthe weather. Yet, there are two problems to be solved. The first is to getgovernments, airlines and airport officials to agree to basic levels of safetyaids. The second problem is to find a way of meeting these basic requirements.
But no matter how well theequipment works, operators of the equipment still play an important role.Communications between pilots and ground controllers are extremely important toair safety. It is worth pointing out that the mishearing or misunderstanding ofinstructions in English, and the use of another language, in an internationalconversation, has led to two recent aircraft accidents. A new type ofinstrument (仪器) called FLIGHTWATCH would help pilotsprevent airport collisions. It would be particularly helpful near airports.
1. The increasing number of flightsleads to the fact that _____.
A. flying is nolonger limited in the sky
B. there is noempty space for aids to aviation control
C. piloting andcontrolling planes is getting more difficult
D. the pressure onthe ground becomes greater
2. There is uncertainty about airsafety because _________.
A. planes become biggerfor the increasing number of passengers
B. money spent onelectronic equipment is far from enough
C. suitableelectronic equipment hasn’t been invented yet
D. it is dangerousfor planes to take off or land
3. The underlined word “collisions”probably means _______.
A. accidents inwhich two planes hit each other
B.misunderstandings between pilots and ground controllers
C. quarrels amongpassengers
D. breakdowns ofnew types of instrument
4. It can be inferred from the passagethat _______.
A. governments andofficials have paid great attention to air safety
B. there should bemore companies to sell new safety aids
C. English shouldbe used in an international conversation
D. understandingbetween pilots and ground controllers should be improved
试题答案
答案：ADBC
解析：1. 细节判断题。原文第一节中“…But, with the number of flights increasingeach year, this emptiness (=miles of empty space) no longer exists. Researchersin the world of aviation are worried about the increasing pressure on pilotsand 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 andbigger aircraft and airports to deal with the vast (=large) increase inpassengers traveling by air. Only a small percentage of this money is spent onnavigation 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：“Researchersare worried about the increasing pressure on pilots and ground controllers. Andincreasing collisions, occurring at or near an airport, have called attentionto 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。
