    Mr. Li lives in a small city. Bad traffic is a big problem there. There are too many cars but there are not enough roads. Buses are the only kind of public transport(公共交通). There isn't a subway. There are traffic jams (交通堵塞) all the time. Most people don't like driving. One day, Mr. Li is going to have an important meeting. He gets on a very crowded (拥挤的) bus. There are lots of cars on the road so the bus is moving very slowly. Mr. Li is very late. When he gets to the meeting room, there is no one there. The meeting is over!
