Nowadays ,with the increase of the private cars,the traffic jam and the air pollution are more and more serious.It has become a common corcern.As for me ,I also think it is necessary to take some immediate measures to solve the problem.There are several things the government should do.First,people are supposed to depend less on the private cars and go out by the public vichels.Second,people should be required to drive their own cars by the last number of the car numbers .Third,the government should develop the public transportion so that people would like to use their cars less.(时间限制,字数不够的话可以追加提问）98个字数- - 不太够,再加个两三句话?在third 那一句前加 If the number of cars out is limited,it will be a effictive way to develop the situation.最后加一句Only everybody put himself in the project can we solve the problem in the root.
