     I started my school life at the age of six. At first the school for me, a boy, meant play, play and more play

instead of sitting in the classroom and learning something. However, I changed the way I used to behave (表现) at school with the help of my teachers. I tried my best to do well in my schoolwork and follow the school rules.

     Growing and learning were great fun. Every year we had different kinds of school trips. Not only could we

learn things from them, but also we were given many projects (课题) as homework. It helped us know more.

At the same time, we made many good friends. In Grade 8, I won prizes in drawing and English speech

competitions. When I was in Grade 9, I realized that I should give all my attention to my studies because I was

going to take the exams to get into senior (高级的) middle school.

ups and downs (苦乐; 盛衰) that influence his life. School is a place where all of us learn to care and share.

success, school plays a key role. I can describe my school in "Three Ss". They are: Small, Sweet and Simple.

My school was the best, is the best and will always be the best.
