河北三年级下册英语电子课本第三课 When you are in Hongkong,you must be very careful in the streets because the traffic drives on the left.It is different from that in other areas of China.If you are the first time to come to Hongkong,you must look to the right side and then the left before you cross the street. If the traffic lights are red,the traffic must stop.Then people on foot can cross the road carefully.But if the traffic lights are green,the traffic can go.People on foot mustn't cross. When people go to or come from work in the morning and evening,the streets are very busy.Traffic is the most dangerous then,especially for the children. When you go by bus in Hongkong,you have to be careful,too.You must always remember the traffic moves on the left.So you must be careful.Have a look first,or you will go the wrong way. In Hongkong,there are many big buses with two floors you can sit on the second floor.From there you can see the view of the whole city①well.It's very interesting. 本文来源：https://www.wddqw.com/doc/ee84b1ed30d4b14e852458fb770bf78a65293a1a.html
