Tom is my new classmate.He is from the America.Some of my classmates have become good friend with him.They often talk happy together.I also want to join them or talk with them.But my written English is not so good.I am afraid that they will laugh me when I talk with them on English.When I was in junior middle school,I work very hard at English.In fact ,I did very well in the examinations so I learnt English grammar very well.However,now I don't think that is enough.They should also learn to speak English.
