Long long ago, there was no paper in the world. People had to write characters(汉字) in bamboo slips or stones.Then there was a man named Cai Lun who was a Chinese man. He made people use all kinds of things to invent paper. From then on, people can use paper to write on. Paper is a great invention. We always remember the great inventor Cai Lun. Nowadays paper is very useful in our work, study and our life.It really means a lot to human beings

    Mr. Black decided to know more about the different jobs of his students' parents. But some of students were laughing as he talked with Mary. Betty shouted, "Mary's father is a garbageman!"Then everybody in the class laughed out loud. Mary felt her face tum red.

    "Be quiet! Stop laughing!"Mr. Black said," It is difficult but useful to be a garbageman. We should all be thankful to Mary's father."

    Mary's father came to walk her home from school as usual, but she didn't run up to him the way she always did. When they got back home, Mary went to her room and cried for a long time. Her father came into her room, "What happened? Why are you so sad?"

    Mary told her father what happened and looked at him sadly. He didn't seem angry or hurt, "Well." He said," They are right. Being a garbageman is a dirty job. Tomorrow's Saturday. Come to work with me, Mary."

    Mary wrinkled her nose because of the bad smell. "Don't worry. In five minutes you won't smell a thing." said her father.

    Everybody there was working hard, and they seemed to have a good time. Mary's father handed her a pair of gloves and told her to get the little plastic bags and throw them into the truck.

    It was fun, but also hard work. At last, no more garbage was left and Mary felt very proud and happy.

    "Garbage makes us uncomfortable and unhealthy but when we clear it away, everything is nice and clean. You can make yourself happy only by making others happy."

    Mary gave her dirty, smelly garbageman daddy a big kiss because she regarded him as an unselfish man. Now whenever someone asks Mary what her daddy does, she says, "He is a garbageman! Everyone makes garbage, but my daddy takes it away!"

    My name is Lucy. I am now in China. I am a student of No. 4 Middle School. There are some clubs in our school. They are an English club, an art club, a music club, a ball game club, a swimming club, a chess club and a computer club. There is a "Show Yourselves (你们自己)!" Festival in our school. On that day, students from different clubs show their talents in difficult ways (用不同的方式). They can sing English songs and draw. They can play the guitar, the violin, the piano and drums. They can also play chess and show us their swimming skills (技巧). They like this festival very much. I join the art club. I draw many nice pictures for the festival. That makes me very happy.
