阅读理解。 When you are in England, you must be very careful (小心) in the street because the traffic (交通) drives on the left. You must look at the right first and then the left, and then you can go across the street. If the traffic lights are red, the traffic must stop. Then the people on foot can cross the road. If the traffic lights are green, the traffic can go. People on foot mustn't cross. When you go by bus in England, you have to be careful, too. Always remember the traffic moves on the left. Have a look first, or you will go the wrong way. In many English cities, there are big buses with two floors. You can sit on the second floor. From there you can see the city very well. It's very interesting. 1.  判断正（T）误（F）。 (     ) (1). The traffic in England drives on the right. (     ) (2). When the traffic lights are green, people on foot can cross the street. (     ) (3).
