Question

There are little cars that may some day take the place of today’s automobiles(汽车). If everyone drives such a little car in the future, there will be less pollution in the air, there will be more parking space in cities, and the streets will be less crowded. The space now for one car of the usual size can hold at least three such little cars.

The little cars will cost much less to own and to drive. Driving will be safer, too, as these little cars can go only 65 kilometers an hour.

The cars of the future will be fine for going around the city, but they will not be useful for going far away. If the car is powered by electricity, it will have two batteries—one battery for the motor and the other for the horn (喇叭), signals (信号灯), etc. Little cars which are powered by gas will go 45 kilometers before needing to stop for more gas.

If big cars are still used along with the small ones, two sets of roads will be needed to set up in the future. Some roads will be used for the big, fast cars, and other roads will be needed for the small, slower ones.

1. What’s the advantage (优势) of the small cars?

A．There won’t be so much pollution and the small cars won’t be so expensive as the big ones.

B．It will be safer to drive these small cars.

C．There will be more space for cars to park.

D．All of the above.

2.  Two sets of roads are necessary in the future in order to      .

A．prevent car accidents

B．make the city more beautiful

C．let small cars run fast

D．limit the speed of the cars

3.  Which of the following is true according to the passage?

A．A car of the usual size now is three times as big as the small car.

B．The small car with a speed of 65 kilometers an hour is much more useless than a car of the usual size.

C．the little car will be safer but cost more.

D．The little car will need more gas.

4.  The best title for this passage should be      .

A．Big Cars and Small Cars                   B．How to Drive Small Cars

C．Cars for Tomorrow                      D．Cars for Everyone

【解析】

试题分析：这篇文章主要讲的是在未来，可能会有一种小型车代替现在的汽车，这种小型车会更环保，也更节能，更经济，更安全，即可以用电，也可以用油。那样的话，也需要建造两种道路分别使用于大型高速的车和小型慢速的车。

1.细节题。根据第一段If everyone drives such a little car in the future, there will be less pollution in the air, there will be more parking space in cities, and the streets will be less crowded. 如果将来人们开小型车，那将会排放更少的废气到空气中，城市里也将会有更多的停车位，并且街道就不会很拥挤。根据第二段The little cars will cost much less to own and to drive. Driving will be safer, too。小型车只需花费很少的钱就可以买到，而且更加的安全。由此可知，A,B,C都正确。故选D

2.推断题。由最后一段two sets of roads will be needed to set up in the future. Some roads will be used for the big, fast cars, and other roads will be needed for the small, slower ones.将来需要建设两组道路，一组道路用于大型，高速的车；一组用于小型、慢速的车。由此可了解到，这样的目的是为了防止交通事故的发生。故选A

3.细节判断题。根据第一段The space now for one car of the usual size can hold at least three such little cars.平常汽车所需的空间是这种小型车所需空间的三倍。可知，平常汽车的体积是这种小型车的3倍。故A正确。

由第二段可知，文章只是说这种小型车的速度只有65公里每小时，并没有说比通常大小的车要无用的的多。故B错误

由第二段The little cars will cost much less to own and to drive. Driving will be safer, too,可知，这种小型车又便宜又安全。可C错误。

由第三段Little cars which are powered by gas will go 45 kilometers before needing to stop for more gas.由汽油驱动的小型车在需要加油钱可以行使45公里。文章并没有提到这种小型车需要更多的汽油。故D错误。

所以，本题选A

4.主旨题。本文主要讲的是在将来，可能会有一种小型车，这种车将更节能，更环保，即经济又安全。所以本文的标题应该是Cars for Tomorrow 。故选C
