九、阅读理解。
In Hong Kong, all the buses and cars drive on the left side of the road. Before you cross the street, you must look to the right and then to the left. When the traffic lights are red, the traffic must stop and people can cross the zebra crossing. When the traffic lights turn green, the traffic can go and people mustn’t cross the road. There is usually heavy traffic on the road in the morning and in the evening when people go to or come from work. When you want to travel by bus, please always remember the traffic keeps to the left. Have a look first, or you may go the wrong way. In this busy city, there are a lot of big buses with two decks(层). I think it is great to sit on the second deck. From there you can watch the city very well. How interesting!
