这是半月前写的,我这个人不喜欢背模板,经过两次自己修改,请大家看一下能得几分,也好让我对自己的水平有个数.谢谢 since cars were invented nearly 100 years ago, they have improved our life a lot. with cars, we can go everywhere we want to go , convey heavy goods to remote place, and save much time to do other things which are more important to us .so it seems that we humans now can not live without cars. but nowadays there is a statement that there will be fewer cars in 20 years than those are today. may be these people feel that cars have brought some problems, for instance some influence to environment and the poor transportation situation of cities, to our society .to me , i do not believe that cars will withdraw from our life. some evidence supports my idea. First of all , there is no doubt that a car is so effective that there is no other transportation can compare with it. for example, the trains and planes have their schedules, if one has departed out, we have to wait for the next one. on the other hand, the ships and bicycles are too slow. sometimes my father will give me a ride if i may be late for school, that saves much time that may be used on road. so cars will still be the best choice for us in future as transportation. Also cars will be more economical in the future. with the development of technology and market competition, the cost of making a car will drop to a much lower level, meanwhile ,the price of a car must go down too. at the same time, people's living condition is always being improved ,so more and more families can afford buying cars belong to themselves. in my community, every year i can see more and more neighbors drive their cars to work or take vacation ,and the parking lot has been more crowd .under this trend ,how will the number of cars all over the world decrease? Moreover, we have the confidence that our scientists can resolve the problem of the waste gas discharged by cars . and by further research, scientists will eventually find cleaner energy for cars, for instance ,the hydrogen , methane and solar energy which are very promising now. the next step is just putting them into widely use. at that time ,the influence of cars to environment will come down to the lowest level. cars can be more environment friendly Though many people will say that if so many cars run in cities ,whether the traffic condition can afford the pressure brought by them. yes ,it is actually a big problem need to be resolved. with the phenomenon of urbanization ,the government gives much financial assistant to the construction of city road and highway. under this situation ,this political decision will efficiently shift the road capability to meet the demand of traffic. in conclusion, during the next 20 years ,human beings can come over the difficult and cars will make more contribution to human civilization. so we can see more cars running on the road.
