When you drive, there are some things you must do and some things you mustn’t do. For example, when you come to a traffic light, a red light means you must stop. A green light means you can go if it is safe.

There are also lots of traffic signs you must understand. For example, when there is a stop sign, you must stop, and then you must look carefully. You mustn’t continue to drive, because it is not safe. When you see a no-entry (禁止进入) sign, you mustn’t turn into that road.

If you see a keep-left sign, you must drive to the left of it, not to the right. A speed limit (限速) sign, for example, 70 kph, means you mustn’t go faster than 70 kph, but you can go more slowly. Safe driving.

Hello, my name is Li Lin. You can call me Jack. I’m a 14-year-old schoolboy. Now. I am studying at a school in the UK. Let me tell you about the fun things I do in this country.

I like riding my bike in the UK. I can get anywhere on my bike in Cambridge. It’s really fun. But riding a bike in the UK is different from riding in China.

First, you have to ride on the left of the road. In China, you ride on the right. When I went to the UK, I rode on the wrong side. Cars ran fast by me. It was terrible.

UK bikes have lights (灯) on them. They have a white light at the front and a red one at the back. You use them at night and early in the morning.

In China, bikes usually have a stand (支架). But you can’t find them on most UK bikes. Why? You can’t leave your bike where you want. You have to put it in a bike park. It’s a good idea.
