2．North China has suffered serious smog（雾霾）recently，especially in big cities like Beijing．What are the reasons for the problem？One of the reasons is the car emission（汽车尾气排放）．With more and more cars on the road，there's no doubt that the climate（气候）is becoming more and more terrible．
As we know，more and more people like driving in China．On one hand，some people think that they should have a car when they have enough money，and then it's easy to go out and they can feel comfortable．On the other hand，a growing number of people hope to use their cars to show off（炫耀）．What's more，years of research has show that one of other reasons for the traffic problem is the driving habit．For example，many young people enjoy driving very fast，so they can feel excited．Most of them only care about the speed rules．
Many governments are working at how to make the traffic better．In my opinion，the governments should educate those people who have cars or plan to buy cars．The governments must make them know that the climate is very serious and set up a much more perfect traffic control system to solve the traffic pressure．
