如下：
An Unforgettable Lesson 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.
难忘的一课我们怎么能忘记张先生上个月给我们上的一课呢？张老师是我们学校唯一一位上了年纪的老师。他去年应该退休了。
但他不想离开他的讲台，不想离开所有的学生，一直呆到上个月。4月22日，星期三上午，他像往常一样站在教室门口。铃声响了，张老师出现在讲台上。令我们惊讶的是，他穿着几年前第一节课穿的外套。
“孩子们，很抱歉，这是我给你们上的最后一课……”他一声令下，热泪盈眶。听到这些话，我们都感到震惊。“为什么？张先生。你为什么这么说？”原来张先生得了肺癌。
他很久以前就知道了，但他没有告诉我们，因为他不想让我们担心他。现在病情恶化，他不得不接受治疗。我们不相信，也不相信！在课堂上，张老师鼓励我们努力学习，将来做一个好老师。这是我难忘的一课，我将永远铭记在心。
