    Mr Scott was the owner of a shop. He lived by himself in a small room above his shop. He was always afraid

that someone might break into his shop at night.

    One day, when he checked his money after closing up, he found he had almost 10,000 dollars. He thought

keeping so much money in the shop was a dangerous thing. So he took the money with him to his bedroom,

put it in the pocket of his coat and went to bed with his coat on. At midnight the doorbell rang and woke him

up. He got out of bed and called out in a shaky (颤抖的) voice, "What do you want?" Under the street light

stood a policeman, "Sorry to wake you up," the policeman said, "but all the lights are on in your shop. I think

you just forgot to turn them off when you closed up."
