    Believe it or not, many of the biggest change in how English is spoken have come from common people in the streets. And one of the most important places which English has changed is the playground! These playgrounds can be any place where the young people meet, such like a sports field or a beach. Often words using by black kids in big cities become popular for other kids many years later. On the beaches of southern California, teenagers invented words to describe what they felt when they surfed. These words found its way into the high schools and then to other places. Similar changes happen among young people in Ireland and Australia. Children from one group would find ways to play with another group more easily. Often they made new words just develop an identity different from their parents.

I'm Cindy, a student for electronic engineering. To tell to you the truth, it wasn't my choice—it was my parents. I wanted to study psychology and they said I wouldn't get the good job. I wish I will not have accepted by the school to do engineering. I'm sitting in the library now and I ought to be doing some physics problem but instead I'm reading Erich Fromm's Escape from Freedom. I think my parents should read this as good, so they would understand us better.

    I still remember how I become a good table tennis player. The first day I went to high school, I saw some of my classmates playing the table tennis. Amazed at how skillful they were, I was determined to be just as good. Late on, I often watched them carefully learn their techniques. Then I kept practiced until I became confident enough to challenge him. At the end of the term I became one of the best player in my class.

    I am really proud in this experience. It helps me realize what we all can fulfill our potential and have our goals achieve through hard work. It also helps me better understand the proverb “Practice makes perfect.”

Dear Mr Smith,

    How are you? As a exchange student, I am writing to tell you I would prefer to move into a single room in next term, as I find it inconvenient share a room with others. My roommate often held parties at night, made much noise. Besides, his friends are always visiting him, that disturbs me a lot. So I hope to draw your attentions to this problem. If you think in my position, I am sure he will agree that the only solution for me is to get a room of my own, one not in the same building and as near to the school campus as possible. I would be gratefully if you could do me the favor.

    Best wishes.

Yours sincerely,

Li Ming
