On a rainy day, about 150 volunteers worked for eight hours to clean up Carson Creek that is near a river. About nine tons of trash (垃圾) was taken out from there.

         "We did a good job," said Alan Specter, the organizer of the event. "We've planned to come back here one more time, three years from now. Of course, we hope that there won't be so much trash next time."

         The trash came in all shapes, sizes and colors: bottles, bicycles, batteries, furniture, clothing, plastic bags, dolls and even a golf bag with a full set of golf clubs (高尔夫球杆).  

         The dirty and tiring work was done by two volunteering groups - Save the Bay and Watch the Whales. Most of the volunteers came from a local police station and a fire station. And some of them were old people who had already got retired.

         That day, it rained a little. All of them wore boots and raincoats. The work took place along a two-mile river with over 500 big yellow trash bags everywhere.

         No one found anything that cost much. A five-year-old boy found an earring which he thought might be worth a million dollars. He said he'd sell it. Then he'd donate half of the money to Watch the Whales, and use the other half to buy his favourite ice cream every day.

         Many people laughed at the boy's story. However, it was easily found that the environment there did become better.

    Mark Twain was an American writer. One day he went to a city by train. He wanted to see one of his friends there. He was a very busy man, so he usually forgot something.

    When he was on the train, the conductor asked him for his ticket. Mark Twain looked for the ticket here and there, but he couldn't find it. The conductor knew Mark Twain. She said. “Show me your ticket on your way back. And if you can't find it, it doesn't matter.”

     “Oh, thank you!” said Mark Twain. “But I must find the ticket. If I can't find it, how can I know where I'm going?”

    Jerry, 30 years old, owned a pizza restaurant. He lived in a flat about one mile north of the restaurant. He walked to and from work. When it was raining, he took the bus.

    Jerry loved gangster（匪徒）movies. When a new on came out, he would go to the theater and watch the new movie three or four times. Then, when it went to video, Jerry would buy the video at Tom's Video Store. Jerry had a home collection of over 1, 000 gangster videos. Old ones, new ones; coloured, black and white; English, Spanish, Japanese-he loved them all. He could tell you the name of the movie, the director, the stars, and the story.

    Jerry finally decided that he would like to own a gun, just like the gangsters. So he saved his money and one day he went to a gun store and bought one for $300. On Saturday morning, he went to the gun club to practise shooting 射击）. He was in the club for only 10 minutes when he accidentally（偶然）dropped his gun. The gun went off, and the bullet（子弹）went into Jerry's right knee（膝盖）.

    Jerry now walks with a walking stick, just like some gangsters.

Dear Mom and Dad,

How are you in London? I'm very happy in Tianjin. My class is not big. My classmates are all nice to me.

Now I have two good friends in my class. They are Wang Tao and Fang Fang. Wang Tao is a boy and Fang Fang is a girl. Wang Tao is thirteen. We are of the same age. Fang Fang is twelve. Wang Tao is tall. We often play basketball after school. He is good at it. His favorite teacher is Mr Hu, the PE teacher. Fang Fang likes music, and she likes Miss Gao best. What about me? I like Chinese very much, and I want to learn it well. My Chinese teacher, Mr Li often helps me. I like him best. Wang Tao and Fang Fang often help me with my Chinese, too.

I'm happy to have good friends like them.

Yours,

Mark
