1、历年英语四级阅读全解析（2002-2008）2002.1Passage oneQuestions 21 to 25 are based on the following passage.Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a day in the not-too-distant future when all autos will be abandoned and allowed to rust. Other authorities, however,
2、think the auto is here to stay. They hold that the car will remain a leading means of urban travel in the foreseeable future.The motorcar will undoubtedly change significantly over the next 30 years. It should become smaller, safer, and more economical, and should not be powered by the gasoline engi
3、ne. The car of the future should be far more pollution-free than present types.Regardless of its power source, the auto in the future will still be the main problem in urban traffic congestion (拥挤). One proposed solution to this problem is the automated highway system.When the auto enters the highwa
4、y system, a retractable (可伸缩的) arm will drop from the auto and make contact with a rail, which is similar to those powering subway trains electrically. Once attached to the rail, the car will become electrically powered from the system, and control of the vehicle will pass to a central computer. The
5、 computer will then monitor all of the cars movements.The driver will use a telephone to dial instructions about his destination into the system. The computer will calculate the best route, and reserve space for the car all the way to the correct exit from the highway. The driver will then be free t
6、o relax and wait for the buzzer (蜂鸣器) that will warn him of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway.21.One significant improvement in the future
7、car will probably be _.A) its power sourceB) its driving systemC) its monitoring systemD) its seating capacity（A）22.What is the authors main concern?A) How to render automobiles pollution-free.B) How to make smaller and safer automobiles.C) How to solve the problem of traffic jams.D) How to develop
8、an automated subway system.（C）23.What provides autos with electric power in an automated highway system?A) A rail.B) An engine.C) A retractable arm.D) A computer controller.（A）24.In an automated highway system, all the driver needs to do is _.A) keep in the right laneB) wait to arrive at his destina
9、tionC) keep in constant touch with the computer centerD) inform the system of his destination by phone（D）25.What is the authors attitude toward the future of autos?A) Enthusiastic.B) Pessimistic.C) Optimistic.D) Cautious.（C）这篇材料讲的是未来汽车的问题。第一段先是举出了两种截然相反的观点：“在不久的未来，汽车将会被人类废弃（all autos will be abandon
10、ed and allowed to rust）”，“在可预见的将来，汽车依然会是城市交通的主要方式（the car will remain a leading means of urban travel in the foreseeable future）”。这样本文讨论的侧重点也就呈现出来了这里将要讨论的是汽车的“未来”。下文接续第一段所提的第二个观点，说明未来被人类继续使用的汽车可能会发生的变化。未来的汽车会变得更小，更加安全，也更有经济性，同时不会使用汽油驱动（smaller, safer, and more economical, and should not be powered b
11、y the gasoline engine），污染也会比现在的汽车小得多。以上算是未来汽车相较现在的优点，不过，未来的汽车也依然存在问题，那就是交通拥堵（still be the main problem in urban traffic congestion）。但作者马上提出了解决办法：自动公路系统（automated highway system）。最后的两个大段对这一系统的工作原理进行了解释。汽车进入自动公路系统后，车身上会有一条伸缩臂与铁轨连接，此时汽车的动力便由系统提供电力控制（解决了污染问题），而汽车的操控则转交给中心电脑，由电脑监控汽车所有的运行动作（第四段）。司机所要做的是只是
12、用电话输入指令，告诉系统所要到达的目的地。系统会计算最佳路径，同时保证行进路径的畅通。这时，司机就有时间放松了，因为快要到达目的地的时候系统会自动发出提示（第五段）。这一系统的效率如何呢？它在一个小时内的容量是10000辆汽车，而如今的公路只能容许1500-2000辆汽车通过（will be able to handle 10,000 vehicles per hour, compared with the 1,500 to 2,000 vehicles that can be carried by a present-day highway）。21. A题目问未来汽车的一项重要发展很可能是A
13、，动力来源。B，驾驶系统。C，监控系统。D，可乘坐人数。第二段对未来汽车的可能发展做了展望：It should become smaller, safer, and more economical, and should not be powered by the gasoline engine. The car of the future should be far more pollution-free than present type，这里提到了5种可能的情况，包括大小（smaller），安全性（safer），经济性（more economical），动力来源（not be power
14、ed by the gasoline engine），环保（more pollution-free）。四个选项中只有A与其中一种情况一致，本题选A。22. C题目问作者主要关心的问题是什么。A，如何实现汽车无污染。B，如何制造更小更安全的汽车。C，如何解决交通拥堵问题。D，如何发展一套自动地铁系统。上一题考查了第二段，那么这一题应该考查第二段以后的内容了。第三段指出the auto in the future will still be the main problem in urban traffic congestion，即未来汽车依然会存在交通拥堵问题。此后的两段全部围绕如何解决交通问题
15、展开，说明了一种新的公路系统如何可以解决这一问题。这样 的话，本题的答案应该是C。A和B在第二段中都提到了，但只是一笔带过，没有继续论述。D有一定迷惑性，要注意D说的是subway系统，而不是文章所着 力说明的highway系统。D这个选项应该是源于第四段which is similar to those powering subway trains electrically这句，但这里仅是把highway系统的一项装置（rail）和subway（地铁）的装置进行对比而已（which指代前面的 rail，is similar to是“与相似”，power做动词讲，指为地铁列车提供电力。全句意思
16、就是“与那些在地铁里为列车提供电力的rail一样”）。23. A题目问在自动公路系统中，是什么为汽车提供电力。A，一根铁轨。B，一台发动机。C，一支可伸缩的机械臂。D，一个电脑控制器。文章讲到自动公路系统的动力问题是在第四段。第四段一共三句话，第一句讲的是汽车进入系统后，会从车身伸出一条可伸缩的机械臂，搭在一根铁轨上。第二句讲 的是与铁轨连接后，汽车就交由公路系统提供电力作为动力。第三句讲的是汽车的控制问题，讲的是汽车的操控完全交予电脑。从这三句话可以看出，机械臂是从汽 车车身伸出的，不会提供电力，仅起到一个连接铁轨的作用。铁轨通过机械臂为汽车提供电力，并开始以电力作为动力，与发动机无关了。电脑只起控制汽车的作 用，与动力无关。这样，本题应该选A。24. D题目问在自
