I first met Li Ming at a friend birthday party five years ago. Then I invited Li Ming over in my place. We listen to my CDs together and soon become best friends. Three years ago, Li Ming’s parents invited I to spend two wonderful week in Qingdao with them during the summer holiday. Li Ming and I loved walking along the beautifully beaches there. Last year I was ill but had to stay in hospital for a week. Li Ming came see me every day. Then his father has changed jobs and they moved to another city. Since then we haven’t see each other much. But we’ve kept writing to each other.
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.
It was 7:15 in the morning of February 8, 2007． I was walking along Park Road towards the east while an old man came out of the park on the other sides of the street． Then I saw a yellow car drive up Third Street and made a right turn into Park Road． The next moment the car hit the man while she was crossing the road． He fell with a cry． The car didn’t stop and drive off at full speed heading west． I noticed the driver was young woman wore a pair of glasses and the plate number was AC864． After two minutes later, I stopped a passed car and took the old man to the nearest hospital．
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.
