I've had quite a lot of lessons in my school life. Among them the one given by an American young man is the most unforgettable.

It was on Tuesday morning in May. Our teacher told us all of a sudden that an American would give us an English lesson. Then in came a young man. He greeted us in English and then began his class. It was quite different from those we had before. During the whole class he taught us several English songs, played games with us and helped us act out a dialogue. He neither taught us English grammar rules nor asked us to do lots of written exercises. He was not serious at all. He was always smiling at each of us.Happy time was always short. Before we knew it, the class was over. We took a photo with our American teacher in the classroom.

I will never forget his smile, his songs and everything he had done in his class.

我在学校上过很多很多的课。其中，一位年轻的美国老师上的课最令我难忘。

那是五月的一个星期二的上午，老师突然告诉我们，一位美国老师将给我们上一节英语课。随后进来了一位年轻人。他用英语向我们打过招呼，然后就开始上课了。他的课与我们以前的课大不相同。整节课，他教我们唱了几首英语歌，与我们一起做游戏，表演了一个对话。他没教我们语法，也没让我们做大量的笔头练习。他一点也不严肃，一直对我们每个人微笑。欢乐的时光总是短暂的，很快就下课了。我们和美国老师一起在教室里合了影。

我永远不会忘记他的微笑，他唱的歌，他在课上所做的一切。
