Today I'd like to tell you something that I experience in the City Park. In the afternoon of last Sunday, my friend and I were taking a walk along a river in the City Park, when suddenly we heard a boy call for help in the river. We jumped into the river or pulled the boy out. Then we made him to breathe using the mouth－to－mouth way.Before the boy came to himself, we sent her to hospital at once and telephoned his parents.The boy was saved. His parents were very thankful us and the doctors thought high of our first aid. We realized that knowing first aid is very help and important because it can help you to save lives.
Dear sir,
Last year I buy a refrigerator in your store on Chang An road. We all like shape of the refrigerator. And recently I find something is wrong with it. It begins to make noise when it turned on. At first it is low but gradually it become louder and louder. To make the matter worse, it even stops working sometimes. We all feel disappointing. I am writing you to ask for help. Would you please send a people to repair it? I will at home this weekend. Please call me before you come to here. My telephone number is 6606.5531. Thanks you very much.

I often quarrel about my mother over whether I can watch TV after school. She holds view that senior three students have to make fully use of every minute to work hard at their lessons. It seems to me that once I am allowed to do that, I’ll unable to control myself and forget all about my study. She also thinks it is bad for my eye. But I really can’t accept her ideas. In my opinion, watch TV can set my mind at rest after a day’s hard works. Besides, it is important for us to know what had happened at home and at abroad. Thus, we shouldn’t be forbidden to watch TV.

Today we were organized for a short trip to the West Hill. We set out by the school bus at 7:30 a.m. The weather was pleasure and every one of us was excited. After two hour’s ride, we arrived there at nine thirty. We began our programs the moment as we got off from the bus. We played games on the hillside and swimming in the river. After that we had our picnic lunch. In the afternoon we walked along the river, that winds around the hills. We took a lot of photo and enjoyed ourselves very much. Time past quickly and we had to come back. It was over five o’clock that we returned school. What a good trip we had today! I’ll never forget it.

Hunger insects kill crops in the fields Farmers spray the field as to get rid of these insects. Does this means that all insects are harmful? No. Many are of great helpful to man. Bees make honey. With bees and other insects, many trees would have not fruit. Silkworms make silk. Some insects eat other insects that kill fruit trees.
