Now I’d like to tell you something took place in my school yesterday. In the afternoon we are all held together for our 18-years-old birthday. At the first we promised that like grown-ups we should be responsible for our society. Then we expressed thank to our parents who experienced hardships to bring us up and our teachers who educated us heart or soul. And our teachers also gave to us cards expressing our good congratulations and wishes to us. Finally, we put on wonderfully performances.

Our school lies on the foot of a mountain with a small river passes by. It used to be a quiet, clean and beautiful place for a school. It is a pity which things have changed after a chemical factory was built near our school one year ago. Every day the factory produces many waste water and some harmful gases. The terribly pollution is harmful to our health. What’s bad, the great noise from the factory had a bad effect on our activities. As a result, our school is no longer what it used to. Our teachers and students are miserable beyond the description.

Recently, we have had a discussing about if we should study by discussing in free class. Views vary from persons to person. Most of the students consider that it is of greatly help studying by discussing in free class, that, they think, can help to find better ways to solve problems. What is much, they believe that they learn by discussing can last longer in their memories. However, there are 35 percents of the students holding the opposite view it is not good. They insist that discussing mean lacking thinking and the loud noises is caused by it will disturb others.

My classmate except me were in high spirits. At the coming party I would have to do some cleanings, for I wasn’t able to dance and sing. During the party, I tried to keep the room being clean. After the party I got rid the rubbish. Enjoying my classmates’ smiling faces, I felt their job worthwhile. When told the room will have been a dustbin without me I thought of a saying, "There must have a use for my talent." You may have no special talent, so as long as you try to do good in everything useful, you’ll find everything is beautiful at every corner of your life.
