     Mr. Black worked in a factory of a small town. He had been there for about twenty years before

one day he was sent to the capital for important business. He was very happy because he had never

been there before. When he started, he asked his wife and daughters if they wanted him to buy

something for them in London. Mrs. Black began to think it over and then she said she wished her

husband would be able to buy a nice umbrella (伞) for her, and so did their three daughters. As he

was afraid he would forget it, he drew an umbrella on his hand. When he reached the station, he

found his hands were dirty. He washed them and the drawing was gone.

     On the train Mr. Black sat opposite to an old woman. The woman's umbrella was so nice that

he carefully looked at it and said to himself not to forget to buy a few umbrellas like it. When the

train arrived at the station in London, he said goodbye to the old woman, took his bag and her

umbrella and was going to get off.

     "Wait a minute, sir," shouted the old woman. "That's my umbrella!"

     Mr. Black stopped to look at his hands and his face turned red at once. He said in a hurry,

"Oh, I'm very sorry, madam! I didn't mean it!"

     Seven days later Mr. Black left the capital. It surprised the old woman that he sat opposite to

her again. Looking at the four umbrellas, the old woman was satisfied with (对……满意) herself.
