One day, our English teacher Mr. White came into the classroom with a book in his hand. He started his lesson with a ___1___ , “Who can describe what stress is like?” No one answered. Then he raised the book and asked, “How ___2___ is the book?”
On hearing the question, we began to think and ___3___ . One student said, “I think it is 100g.” Another student said, “It’s 200g.” Our answers were different. ___4___, Mr. White explained, “It doesn’t only depend on the real weight. It also has ___5___ to do with the time we hold it. If I hold it for a minute, it is OK. If I hold it for an hour, I will have a ___6___ in my right arm. If I hold it for a day, I will have to see a doctor. It is the exact same weight, ___7___ the longer I hold it, the heavier it becomes. This book ___8___ stress. If you hold it without putting it down, sooner or later, you will not be able to keep on. No matter how much ___9___ you have, stop and have a rest for a while if possible. Boys and girls, you should learn to relax yourselves. I am sure you will live a happy school life.”
We all ___10___ Mr. White for giving such a meaningful lesson which made a difference to us.
