The clock struck eleven at night. The whole house was quiet. Everyone was in bed except me. Under the strong light，I looked sadly before me at a huge pile of that troublesome stuff（东西） they call “books”.
I was going to have my examination the
next day. “When can I go to bed？” I asked myself. I didn’t answer，in fact, I dared not.
The clock struck twelve. “ Oh，dear！” I cried. “Ten more books to read before I can go to bed！” We pupils are the most wretched creatures in the world. Dad does not agree with me on this. He did not have to work so hard when he was a boy.
The clock struck one. I was quite desperate（绝望的）now. I forgot all I had learned. I was too tired to go on. I did the only thing I could. I prayed，“Oh，God，please help me pass the exam tomorrow. I do promise to work hard afterwards，Amen.” My eyes were so heavy that I could hardly open them. A few minutes later，with my head on the desk，I fell asleep.
