Three years ago I failed an important exam in my life and became a student in a ordinary school. Disappointing as I felt at the shabby campus and the poorly-equipped classroom, I found the teachers patiently and considerate. Besides, I enjoyed the friendly atmosphere in class. I decided make the best of it. I worked hard and get along well with my teachers and classmates. Whenever I had difficulties, they were always available. Soon, I became one of the top student in my class, and which greatly increased my confidence and got him motivated.
My experience tell me that it is not what you are given but how you make use for it that determines who you are.

Friendship is very importance. Everyone needs friendship. In all our lives we can’t live without friendship just as we can’t live without air and water. Friendship makes us getting on well with one another to
go ahead under different kind of difficulties in the front of us. But real friendship is no easy to come by. True friendship must be sincerely and be based on understand each other but not on benefits of each other. A good friend can always be a good teacher to us. By his advices we are persuading to go the right way. Therefore more friends we have, the better we can improve ourselves.

Dear Mary,
I've received your e-mail. Don't worried about me. I'm getting on well with my research work in the lab. But in my great surprise, you say you will give up learn English. The reason is because you have not done well in it recently and you have lose interests. I'm afraid I can't agree with you. I know it is not easy to learn English, and English is widely used in the world today and it will be important tool in the future. Beside, it is becoming more and more important in our daily life. I am sure that if you study hardly, you will succeed. I'm looking forward to hearing a good news from you.
