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 a huge pile of troublesome things 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 12. “Oh, dear!” I cried, “ten more books to read before I can go to bed!” We pupils are the most wretched(可怜的) 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 hopeless now. I forgot all I had learnt. 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 heavy, so heavy that I could hardly open them. A few minutes later, with my head on the desk, I fell asleep.
