    If you use fire carefully, fire can help you a lot. But if you don't, you will be dangerous.

    People know the danger of fire. It's good for us to know how to protect us from fire.

    First, get a smoke alarm in the house. It can make a loud sound. The sound tells everyone to leave the house immediately (立刻) in case of emergency (紧急情况).

    Next, have an escaping (逃生) plan. Make sure we all know where is the safety exit (出口) of your house. In case of fire emergency, everyone should follow the right way to escape.

    Then, it is necessary for every family to buy a fire extinguisher (灭火器). And also make sure that every family member know how to use it.

    Sometimes fire is dangerous. We must be careful. We know the danger of fire and we should know how to protect ourselves.

    We should get a smoke alarm. So we can find the fire and escape quickly.

    We should have an escaping plan. We should know where the safety exit.

Dear Tom,

    Today we got up very early. We went to the Great Wall by bus. It was very far. It was about three hours by bus. The guide told us the food there was very expensive, so we bought some cakes, juice and peaches. We put them in one backpack, Zhang Fang took the backpack and I took the camera, because he said he was older and stronger than me.

When we got to the Great Wall, we saw many people at the entrance (入口). We had to stand in line and waited. It was our turn at last. We began to climb. At first I counted the steps, but soon I couldn't remember the number. It is too high. We stopped to have a rest for several times. At last we got to the top of the wall. We were so excited! We've become real men!

    There is a cinema on the wall. We saw a movie of the Great Wall. It was evening when we came back. We ate beef and noodles for supper. We had a good day today.
