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 didnt 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 didnt tell us because he didnt want us to worry about him.And now the disease had got worse and he had to receive treatment.We didnt and couldnt believe! In the class,Mr Zhang encourged us to study diligently and be good perons in the future. This was my unforgettable lesson.Ill keep it in mind forever.
