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 and made useless Other experts however think the car is here to stay They hold that the car will remain a leading means of city travel in the foreseeable future
The car will undoubtedly change greatly over the next 30 years It should become smaller safer and more practical and should not be powered 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 essential problem is the automated(自动的)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 hose powering subway trains electrically Once joined to the rail the car will become electrically powered form 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 It is believed that an automated highway will be able to deal with 10.000 cars per hour compared with the 1,500 to 2,000 cars can be carried by a present-day highway

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．

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．

avoid danger and inefficient labour

restore his bodily functions

[ ]
A．

C．
are in a tent
D．
are away from home

Several years ago, my parents, my wife, my son and I ate at one of those restaurants where the menu is written on a blackboard．After a wonderful dinner, the waiter set the check in the middle of the table．That’s when it happened：my father did not reach for the check．
Conversation continued．Finally I realized that I should pick up the check!After hundreds of restaurant meals with my parents, after a lifetime of thinking of my father as the one with dollars, it had all changed．I reached for the check, and my view of myself suddenly changed．I was an adult．I was no longer a kid．
Some people mark off(区分)their lives in years, I measure mine in small events．I didn’t become a young man at a particular age, like 16, but rather when a kid who wandered in the streets called me “mister．” These events in my life are called “milestones”(里程碑)
There have been other milestones．The cops(policemen)of my youth always seemed big, even huge, and of course they were older than I was．Then one day they were suddenly realized that all the football players in the game I was watching were younger than I was．They were just big kids．With that milestone gone was the dream that someday, maybe I, too, could be a football player．Without ever having reached the hill, I was over it．
I never thought that I would fall asleep in front of the TV set as my father did．Now it’s what I do best．I never thought that I would go to the beach and not swim, yet I spent all of August at the shore and never once went into the ocean．I never thought that I would appreciate opera, but now the combination of voice and orchestra attract me．I never thought that I would prefer to stay home in the evenings, but now I find myself passing up parties．I used to think that people who watched birds were strange, but this summer I fond myself watching them, and maybe I’ll get a book on the subject．I feel a strong desire for a religious belief that I never thought I’d want, feel close to my ancestors(祖先)long gone, and echo my father in arguments with my son．I still lose…
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．
