　　Some experts feel that cars are certain to fall into disuse．They see a day in the not-too-distant future when all cars will be deserted(被遗弃的)and made useless．Other experts, however, think the car is here to stay．They hold that the car will remain a lead-ing means of city travel in the foreseeable future．

　　The car will undoubtedly(无容置疑的)change greatly over the next 30 years．It should become smaller, safer, and more practical, and should not be powered⑨ by the gas engine．The car of the future should be far more pollution-free than present types．

　　Unless changes take place in the power system, the car in the future will still be the main problem in city traffic jams．One suggested solution to this essential⑩ problem is the automated(自动化)system, which seems to hold water．

　　When the car enters the highway system, a small arm will drop from the car and connect with a rail, which is similar to those powering subway trains electrically(用电的，与电有关的)．Once joined to the rail, the car will become electrically powered from the system, and control of the car will pass to a central computer．The computer will then monitor all of the car's movements．

　　The driver will use the telephone to dial instructions about his position and the place he heads for into the system．The computer will find the best way and reserve space for the car all the way to the correct exit from the highway．The driver will be free to relax and wait for the call that will warn him of his coming exit(出入口)．It is believed that an automated highway will be able to deal with 10 000 cars per hour, compared with the 1500 to(2000 cars that can be carried by a present-day highway．

(1)

What is the main concern of the author of the passage?
[　　]
A．	How to make cars pollution free．
B．	How to make cars smaller and safer．
C．	How to solve the problem of traffic jam．
D．	How to develop an automated subway system．

(2)

We can infer from this passage that ________．
[　　]
A．	the car connected to the rail on the highway will be powered by electricity
B．	the lack of oil is forcing people to find new means to power automobiles
C．	the driver under the system will be told where to get out of the highway
D．	the future car will become larger, faster, prettier and less expensive

(3)

What provides cars with electric power in an automated highway system?
[　　]
A．	An engine．
B．	A rail．
C．	A computer controller．
D．	A small arm．

(4)

Which of the following statements is true according to the passage?
[　　]
A．	The driver puts his information in the system by e-mail．
B．	The new system can deal with 10 times as many cars as the present one．
C．	After entering the automated system, the driver needs to do nothing but relax himself．
D．	Some experts are not confident of the future, while the author is in favor of the opposite view．

答案：1．D;2．B;3．B;4．D;
解析：

(1)	推理判断题。根据文章的第三段第一句话“unless changes take place…traffic jams”(句意为：如果电力系统方面不改革的话，未来汽车的主要问题将表现在城市的交通堵塞上)可知：作者最关注的是如何开发出一种自动电力系统。
(2)	推理判断题。A、C两项在文章中是直接叙述不用推测，D项不符合题意。

提示：

(3)	细节理解题。根据文章的第四段第二句话“Once joined to the rail, the car will become electrically powered from the system”可知：一旦汽车被连接在路轨上，汽车就会从系统中获取电力。
(4)	根据文章最后一段可知：A、B、C三项都不符合事实，根据文章第一段可知，作者对汽车的前景看好。

　　Many Americans are turning to Japan, they think, a country of high academic achievement and economic success, for possible answers．However, the answers provided by Japanese preschools are not the ones Americans expected to find．In most Japanese preschools, surprisingly little emphasis is put on academic instruction．In one survey, 300 Japanese and 210 American preschool teachers, child development specialists, and parents were asked about various aspects of early childhood education．Only 2 percent of the Japanese respondents(答问卷者)listed“to give children a good start academically”as one of their top three reasons for a society to have preschools．In contrast, over half the American respondents chose this as one of their top three choices．To prepare children for successful careers in first grade and beyond, Japanese schools do not teach reading, writing, and mathematics, but rather skills such as determination, concentration, and the ability to work as a member of a group．The huge majority of young Japanese children are taught to read at home by their parents．

　　Like in America, there is diversity(多样性)in Japanese early childhood education．Some Japanese kindergartens have specific aims, such as early musical training or potential development．In large cities, some kindergartens are attached to universities that have elementary and secondary schools．Some Japanese parents believe that if their young children attend a university-based program, it will increase the children's chances of eventually being admitted to top-rated schools and universities．Several more progressive programs have introduced free play as a way out for the heavy intellectualizing in some Japanese kindergartens．

　　In the United States, boys and girls start school when they are five years old. In some states they must stay in school until they are sixteen. Most students are seventeen or eighteen years old when they graduate from secondary school. Another name for secondary school is high school.

　　Most children go to public elementary (初小) and secondary school. The parents of public school pupils do not have to pay directly (直接地) for their children's education because tax (税)money supports the public schools. If a child attends a private (私立) school, his parents pay the school for the child's education.

　　Today about half of the high school graduates go on to colleges and universities. Some colleges and universities receive tax money from the governments. A student at a state university does not have to pay very much if his parents live in that state. Private colleges and universities are expensive. However, almost half of the colleges students in the United States work while they are studying. When a student's family isn't rich, he has to earn money for part of his college expenses.

　　Suppose we built a robot(机器人)to explore the planet Mars．We provide the robot with seeing detectors(探测器)to keep it away from danger．It is powered entirely by the sun．Should we program the robot to be equally active at all times?No．The robot would be using up energy at a time when it was not receiving any．So we would probably program it to stop its activity at night and to wake up at dawn the next morning．

　　According to the evolutionary(进化的)theory of sleep, evolution equipped us with a regular pattern of sleeping and waking for the same reason．The theory does not deny(否认)that sleep provides some important restorative functions(恢复功能)．It merely says that evolution has programmed us to perform those functions at a time when activity would be inefficient and possibly dangerous．However, sleep protects us only from the sort of trouble we might walk into; it does not protect us from trouble that comes looking for us．So we sleep well when we are in a familiar, safe place, but we sleep lightly, if at all, when we fear that bears will nose into the tent．

　　The evolutionary theory explains the differences in sleep among creatures．Why do eats, for instance, sleep so much, while horses sleep so little?Surely cats do not need five times as much repair and restoration as horses do．But cats can afford to have long periods of inactivity because they spend little time eating and are unlikely to be attacked while they sleep．Horses must spend almost all their waking hours eating, because what they eat is very low in energy value．Moreover, they cannot afford to sleep too long or too deeply, because their survival(生存)depends on their ability to run away from attackers．

(1)

The author uses the example of the robot in space exploration to tell us ________．
[　　]
A．	the differences between robots and men
B．	the reason why men need to sleep
C．	about the need for robots to save power
D．	about the danger of men working at night

(2)

Evolution has programmed man to sleep at night chiefly to help him ________．
[　　]
A．	keep up a regular pattern of life
B．	prevent trouble that comes looking for him
C．	avoid danger and inefficient labour
D．	restore his bodily functions

(3)

According to the author, we cannot sleep well when we ________．
[　　]
A．	are worrying about our safety
B．	are overworked
C．	are in a tent
D．	are away from home

(4)

Cats sleep much more than horses do partly because cats ________．
[　　]
A．	need more time for restoration
B．	are unlikely to be attackers
C．	axe more active than homes when they are awake
D．	spend less time eating to get enough energy

(5)

Which of the following is the main idea of the passage?
[　　]
A．	Evolution has equipped all creatures with a regular pattern of sleeping and waking．
B．	The study of sleep is an important part of the evolutionary theory．
C．	Sleeping patterns must be taken into consideration in the designing of robots．
D．	The sleeping pattern of a living creature is determined by the food it eats．

　　One day I bought a house．One day－what a day!–I became a father, and not too long after that I picked up the check for my own father．I thought then it was a milestone for me．One day, when I was a little older, I realized it was one for him, too, another milestone．
