　　The cars of the future will be fine for going 6 the city, but they will not be useful for going far away. The little car needs only two batteries(电池)－one battery for the motor, and 7 for the horn and the lights.

Some day little cars may take the place of (代替) today’s cars. They are good for our earth. If everyone    26    such a little car in the future, there will be     27    pollution in the air. There will be more parking places in the cities, and the street will be      28    crowded(拥挤). Now the space for one car of the usual size can hole more than one such little car. Driving will be     29   , because these little cars can go only 50 kilometers one     30   . The future cars will be fine for going around the city, but they will not be     31    for going far away. The little car needs only two batteries(电池),     32    battery for the motor, and the other for the horn(喇叭) and the lights. If we still     33     the big cars along with the small ones; we will need to     34     two kinds of roads. Some roads will be used for the big fast cars,     35   other roads will be needed for the smaller and slower ones.

Scientists are trying to make some small cars that may some day take the place of today’s big cars. If everyone drives such cars in the future, there will be 1_ pollution in the air. There will _2 be more space or parking cars in cities, and the _3_ will be less crowded. Three such cars can fit in__4__ that it is now needed for one car of the usual size.
The little cars will __5___ much less to own and to drive. Driving will be __6___, too, as these little cars can go only 65 kilometers per hour. The little cars of __7___ will be fine or getting out of the city, but they will not be useful for__8__ trips. Little cars which are powered by gasoline( 汽油 ) will go 450 kilometers __9___ needing to stop for more gasoline .
If big cars still are used together with the small ones, _10__ sets of roads will be needed in the future. Some roads will be used for the big, fast cars, and some roads will be needed for the slower, small ones.

　　The cars of the future will be fine for going ___(6)___ the city, but they will not be useful for going far away. The little car needs only two batteries（电池）, one battery for the motor, and ___(7)___ for the horn and lights.

A kind of little cars may some day take the place of today’s cars. If everyone drives such cars in the future，there will be less pollution from the cars. There will also be more space for parking cars in cities，and the streets will be less crowded. Three such cars can park in the space now needed for one car of the usual size.
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 getting around a city，but they will not be useful for long trips. Little cars will go 450 kilometers before needing to stop for more gas(汽油).
If big cars are still used along with the small ones，two sets of roads will be needed in the future. Some roads will be used for the big，quick cars and other roads will be needed for the slower，smaller ones.
【小题1】There is much pollution from the cars today because________.
