    A perform in our city made people think more about an overuse of plastic bags. It called on people use more cloth bags instead of plastic one. In front of a largely supermarket, five volunteers wear white plastic bags and walked through the crowd. Some of the plastic bags worn by the volunteers was collected from customers in two food markets, and all the others were collected by 700 students from a secondary school. On that day, upon leaving the food markets, customers were asking to hand in the plastic shopping bags that they didn't need of. Several hundreds plastic bags were collected within just two hours.

Dear Mr. Chen,

    I will graduate in about a month. I have a lot of to say. During the past three years, you have given me so many help and encouragement, but I have done a lot of things what make you angry.

    When I was in Grade Two, I didn't study hardly. I spent too much time in play basketball.

    As a result, I got bad grades. You tried your best to help me on my English, my study habits and my life. Every time I did everything wrong, you always said, "It doesn't matter." At that time, I was too young and foolish understand you. Now I can see all of these thing. I think that I should say sorry to me. I am very sorry, sir!

    Best wishes to you and your family!

Yours,

Steve

My school life is very colorful and I enjoyed it very much. I'd like share my school life. I have four lesson in the morning and three in the afternoon. My teachers make all our lessons interesting. We can get a plenty of knowledges from these classes. On the other hand, my school life is also filled for many challenges. We have much different exams every term and it is hard for you to get good grades in these exams. So I am required to study very hardly. I also love my classmates and teachers what make my school life wonderful.
