How can we forget the lesson Mr Zhang gave us last month?

Mr Zhang was the only teacher who worked over-aged in our school. He should have retired from teaching last year.But he didn't want to leave his platform, his all students, and stay till last month. On the morning of April 22, Wednesday, he stood at the gate of the classroom as usual. The bell rang and Mr Zhang appeared on the platform. Much to our surprise,he was wearing the coat he wore for the first class a few years ago. Boys and girls, I am sorry this is the last lesson I give you... He wispered,tears came to his eyes.Hearing such words,all of us were shocked. Why? Mr Zhang. Why did you say that? It turned out that Mr Zhang had suffered lung cancer. He knew about that long ago but he didn't tell us because he didn't want us to worry about him.And now the disease had got worse and he had to receive treatment.We didn't and couldn't believe!

In the class,Mr Zhang encourged us to study diligently and be good perons in the future.

This was my unforgettable lesson.I'll keep it in mind forever.

我们怎么能忘记张老师给我们上课的最后这个月？

张先生是唯一一个在我们学校超过退休年纪还在上课的老师。他应该本来应该去年就退休了的，但是他不想离开自己的三尺讲台和他的学生，他一直呆到了生命的最后一个月。在四月二十二日上午，星期三，他像往常一样站在教室门口。上课铃声响了，张老师出现在讲台上。令我们吃惊的是，他穿着前几年他第一次给我们上课时的那件外套。同学们，我很抱歉，这是我给你们上的最后一节课他低声说，泪水涌上了他的眼眶。听到这样的话，我们所有的人都震惊了。为什么呢？张老师，你为什么这么说？原来，张老师患了肺癌。呢就以前他就知道了自己的病情，但是他没有告诉我们，因为他不想让我们知道。

在课堂上，张老师鼓励我们努力学习，将来成为有用的人。

这是我终生难忘的一堂课。我会永远记在心底。
