With the rapid development of our country's economy more and more cars are coming into common families which causes serious traffic jams environmental pollution as well as loss of economy.     As far as I am concerned the solutions to this problem are presented as follows: first of all the governments ate supposed to restrict the amount of car-buying and meanwhile raise the costs of owning private ears. Besides vehicles from other places should be properly limited to enter downtowns. In addition the governments should design the reasonable traffic systems of their own cities.     In a word the traffic jams have increasingly affected aspects of social life. Therefore we must spare no efforts to solve this problem to keep up our country's economic rise.答案不唯一。
