Question

                                B

      Today,more and more people drive cars. Cars make our lives easier,but they also make problems. One of the biggest problems is air pollution (污染) because most cars use petrol (汽油). So the “green” cars will become popular. It means that there will be a few new kinds of cars that don't use petrol. Here are some of them：

      Battery (電池) cars： These cars use batteries to run. Some battery cars are 97% cleaner than petrol cars. But car factories still can’t make a battery that can be used for a time long enough. 

      Fuel cell (燃料電池) cars: Carmakers are now studying how fuel cells can be used to run cars. The only useless thing they will give out is clean water. Fuel cells,however,are still much too expensive to make. Fuel cell cars can be ten times as expensive as petrol cars.

      Solar (太陽能的) cars: This kind of car gets power (能量) from the sun. The cars keep power in batteries. Solar cars may be the cleanest of all. But no one uses them,because people can’t get enough power from the sun to make a car run for a long time. Also,they are very slow.
