In many parts of the world，cars play an important role in daily life and many societies would not exist without them. So the idea that in 20 years’ time, no one will own cars may be hard to believe. But this is the prediction made by a team of transport researchers who are taken seriously, not only by government but also by car manufacturers.
The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. The team there believes that by 2020 all cars will be computerized, which will mean much saving，no accidents and better use of roads. The super-intelligent car of the 21st century will drive itself, and it will not be owned by one individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.
According to Dr. David Davis，who leads the research team, these predictions are based on the rising cost of the car culture, which had blocked up our cities, polluted our air, and caused more deaths than both world wars put together.
Davis says cars will be fitted with some intelligent devices to regulate the distance between one car and another. The car will automatically speed up, or slow down, to match the speed of the car in front. Computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people. By 2010, Dr. David Davis believes, car technology will give motorists a clear view of the road, whatever the weather conditions, by projecting an image of the road ahead on to the car’s windscreen. And by 2020, cars will travel in convoy linked to each other electronically. Cars will be connected by an electronic tow bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the normal amount.” says Davis. “But all the others in the train would bum about ten percent 0f the normal amount, and so produce about ten percent of the pollution.”
【小題1】 We know from the passage that governments and car manufacturers        .

   A. do not believe the prediction that no one will own cars by 2020
   B. are devoted to the technological revolution in car industry
C. consider the predictions seriously

   A. The car will speed up out of control．
   B. We will own as many cars as we want．
C. All cars will be driven by computers．
D. Cars will produce more pollution than present ones．
【小題3】The leader of the research team believes that the present car culture will change because        .
A. cars play a very important role in daily life
B. many societies would stop functioning without cars
C. cars should not be owned by one individual
D. it causes many deaths to human society
【小題4】The expression closest in meaning to the phrase “in convoy” in the last paragraph is        .
A. in line         B. sidelong
C. side by side     D. shoulder to shoulder
【小題5】 What will happen if cars are joined to each other electronically in 2020？

Cars are an important part of life in the United States. Without a car most people feel that they are poor. And even if a person is poor , he doesn’t feel really poor when he has a car.

Henry Ford was the man who first started making cars in large numbers. He probably didn’t know how much the car was going to change American culture. The car made the United States a nation on wheels. And it helped make the United States what it is today.

There are three main reasons why the car became so popular in the United States. First of all, the country is a big one and Americans like to move around it. The car makes the travel the most comfortable and cheapest. With a car people can go to any place without spending a lot of money.

The second reason cars are popular is the fact that the United States never really developed a practical and cheap public travel system. Long distance trains have never been as common in the United States as they are in other parts of the world. Now there is a good system of air-service provided by planes. But it is too expensive to be used often.

The third reason is the most important one, though. The American spirit of independence is what really made cars popular. Americans don’t like waiting for a bus, or a train or even a plane. They don’t like to have to follow an exact timetable. A car gives them the freedom to plan their own time. And this is the freedom that Americans want most to have.

Less oil has caused a big problem for Americans. But the answer will not be a bigger system of public transportation. The real answer will have to be a new kind of car, one that does not use so much oil.

1.We can learn from this passage that Americans ______.

A．spend a lot of money traveling by car        B．travel a lot in their cars

C．seldom travel by plane                   D．use public traffic often

2.Which of the following statements is TRUE?

A．In the United States even the poor own cars.

B．In the United States all the poor have no cars.

C．When an American has a car, he will never be poor.

D．An American will feel poor unless he has a car.

3.In the writer’s opinion, cars are popular in the United States mainly because ___.

A．Americans like to plan their own time

B．The United States does not have enough public transportation

C．Americans will not feel poor when they travel in their cars

D．Americans cannot move around without their own cars

4.“A nation on wheels” in the second paragraph means that _______.

A．everyone in the United States owns a car

B．the United States produces most of the cars in the world

C．cars play an important part in American’ life

D．the United States depend on car industry for its development

In many parts of the world cars play an essential role in daily life and many societies would stop to function without them. So the claim that in 20 years’ time no one will own cars may be hard to believe. But this is the prediction made by a team of transport researchers who are taken seriously not only by governments but also by car manufacturers.

The Human Science and Advanced Technology Institute at Loughborough in the UK is part of an international research program. The team there believes that by 2020 all cars will be computerized, which will mean extremely large fuel savings, no accidents and better use of roads. The super-intelligent car of the 21st century will drive itself and it will not be owned by on individual. Instead, we will have a choice of cars and change them as frequently as we change our clothing.

According to Dr. David Davis, who leads the research team, these predictions are based on the rising cost of the car culture ,which had blocked up our cities, polluted our air and caused more deaths than both world wars put together.

Davis says cars will be fitted with intelligent cruise control devices to regulate the distance between one car and another. Brakes and accelerators (加速器) will become redundant（多余的） because the car will automatically speed up or slow down to match the speed of the car in front. Computers are much safer drivers than people, so cars in a road train will be able to drive much closer together than cars driven by people.

By 2010 Dr. David Davis believes car technology will give motorists a clear view of the road whatever the weather conditions by projecting an image of the road ahead onto the car’s windscreen. And by 2020 cars will travel in convoy linked to each other electronically. Cars will be connected by an electronic tow(牽引) bar to the car in front to form “road-trains”. “The front vehicle in such a train burns the ordinary fuel” says Davis. “But all the others in the train would burn about ten percent of the normal amount and so produce about ten percent of the pollution.

1.We know from the passage that governments and car manufactures ________.

   A. don’t believe the prediction that no one will own cars by 2020.

   B. are devoted to the technological innovation (創(chuàng)新) in car industry.

   C. consider the predictions made by the researchers seriously.

   D. have put the super-intelligent car into mass production.

   A. There will be no brake and accelerator in cars.

   B. We will own as many cars as we want .

   C. All cars will be driven by computers.

   D. Car accident will no longer happen.

3.The expression closest in meaning to the underlined phrase “ in convoy”(Para 5) is ______.

   A. in line B. sidelong C. side by side D. next to one another

4.What will happen if cars are linked to each other electronically in 2020 ?

   B. The weather conditions won’t have effect on motorists.

   C. There will be a decrease in the pollution caused by car .

   D.All trains will burn less fuel than present.
