Some pessimistic experts feel that the automobile is bound to fall into disuse. They see a

day in the not-mo-distant future when all autos will be abandoned and allowed to rust. Other authorities, however, think the auto is here to stay. They hold that the car will remain a leading means of 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 engine. 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 highway 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 computer will then monitor all of the car's 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 to relax and wak for the buzzer(蜂鸣器) that will warn of his coming exit. It is estimated that an automated highway will be able to handle 10,000 vehicles per hour, compared with the 1,400 to 2,000 vehicles that can be carried by a present-day highway.

One significant improvement in the future car may probably be ______.

A．its power source

B．its driving system

C．its monitoring system

D．its seating capacity

答案

A
解析：关键提示出现在第二段第二句，以及第三段开头，可得知需改进汽车的能量来源，C项表示"汽车的监控系统"，有一定的干扰度，文章的第三、第四段都谈到了这一问题。但该问题不是汽车本身需改进的问题。

cording to a global survey of educational achievement. In the 3rd International Mathematics and Science Study, 13-year-olds from Singapore achieved the-best scores in standardized tests of math and science that were administered to 287,896 students in 41 countries in 1994 and 1995．The survey suggests that science and math education is especially strong in the Far East, while well behind those top scores, students from Australia earned higher marks in math than their counterparts in England, who in turn did better than American students. The study collected information on the students' teachers and homes. Not surprisingly, the highest-scoring students had well-educated parents or came from homes containing studying aids such as computers, dictionaries or even such elemental facilities as desks. The study shows that boys generally did better than girls in science, but there was little difference between them in math. Boys scored better than girls in physics and chemistry. There were no sex differences in the life and environmental sciences. In addition to being tested, students in the project were asked how proficient they thought they were in math and science. Students in some countries, such as Columbia and Kuwait, had an overly optimistic view of their skills. Meanwhile, some of the best students from Japan and Korea, for example, were needlessly pessimistic even though they did far better in math than almost all of the other students.
