改:In twenty years there will be fewer cars in use than there are today.
With the development of the science and technology, a conflict between high-technology and sense of protecting environment is coming to our mind gradually. So, people cannot help to asking whether there will be fewer cars in use than there are today.In my opinion, the answer is yes. I will give my explains.
The main reason can account for,i think, is the sense of protecting environment. As the development of the high-technology, people feel more and more comfortable. On the other hand, people also feel the disadvantage of the high-technology. It is universally acknowledged that using cars can bring air pollution, which has bad effect on our lives. A good case for this point is the story of my grandfather. He always complain the climate. The sky was blue when he was a child. However, With much pollution produced by the car, the sky is gray. He advocates to go work by walk, so as most of people in the world.
The other aspect is the replacement of the car. There is no denying that we can use more transports instead of the car. For example:underground ,air plane or bus. "Why not we must use the car". More and more people ask the same question.According to the report, in the city, people prefer to choose the subway other than the car.There is no account that the role of car is not so important as it in a few years ago.
Alough the car has some benefit, such as convinent, fast and so on, there is a whole tendency that car will be out-date and more people will use other transportation otherwise the car. 最后结尾我会再改善,看看句式。umm。。。明天暂停,我要好好研究下以前的错误,你也是,总结一下,后天继续。
