Dear Mr. Wang,
       Someone comes to the office to see you in the morning, but you and your wife are out. He comes here at 10 a.m. Because he is very busy, he goes away half an hour later. He tells me that he is your classmate at college(大学). Now he teaches Chinese in a high school(高中) in this city and he lives near the No. 6 Middle School. He is a very tall man with short hair. He wears a pair of glasses. He tells me his telephone number is  33426685. He is often at home at 7:00 p.m. So you can call him in the evening.

    There are two mice. They are called Bill and Paul. They are good friends. One mouse lives in the country; the other mouse lives in the city. On a sunny day they meet in the street.

Paul: Hi, Bill! Have a look at my house in the country. I'm sure you can enjoy yourself.

Bill: I'd love to. But I hear that the food is not delicious, and your house is not good. Is it so?

Paul: No, that's not true. Go and see!

Then Bill goes to the countryside with Paul.

Bill: Why do you live in a hole in the field? You should come and live in the city. You would live in a nice house made of stone. You would have better food to eat. You must come and see me at my house in the city.

Paul: Thanks! Maybe you are right. I'll visit your house one day.

____days later Paul goes to Bill's house in the city. The house is big and beautiful. They are sitting in the sitting-room, having a big dinner comfortably. Suddenly, there a great noise.

Bill: Run! Run! The cat is coming!

Paul: Oh, no! It's terrible! Both the house and the food are nice, but I do not like living in the city. I enjoy living in my hole in the field, for it is nice to be poor but happy than to be rich but afraid.

Everyone was happy on Saturday morning, but not Tom. He sat in front of a high fence(围栏). "Too bad! It's a nice Saturday morning but I must paint the fence. My friends are playing, but I'm sitting here. " He got up slowly and started to paint. Then he had a great idea. 

His friend Ben was walking down the street and he was eating a big red apple. He saw Tom and said, "Tom, I'm going swimming, but you can't come with me. You're working. "

Tom said, "I like it! I can go swimming every day, but I can't paint a fence every day. "

Ben was surprised and he watched Tom. He painted slowly and carefully, and he often smiled. He looked happy. At this time, Ben wanted to paint too. 

"Listen, Tom, let me paint a little, " said Ben. "I want to try. "

 Tom looked at Ben and said, "I'm really sorry, Ben, but Aunt Polly wants me to do it. You know, I'm very good at painting. My brother Sid wants to do it, but he's not good at painting. "

"Oh, Tom, let me try, please!" said Ben. "Here, you can have my apple. "

Tom was happy but he didn't smile. "OK, Ben, you can paint for a short time. "

Then Tom's other friends came by. They watched Tom paint and they all wanted to try. They gave Tom a new kite, a cat, an old knife, a key and some other things. 

Tom's friends painted the big fence, and Tom just sat under the big tree and watched them. He thought, "When something is difficult to get, everyone wants it. "
