    I am a teacher in a middle school. I have a good friend called Mr White. He is the head of an office. He's often busy and has no time to do the housework. His wife knows him well and does all at home.

    Unluckily, their daughter Rose got hurt in a traffic accident two weeks ago, and had to be in hospital. Mrs White had to look after her there and she couldn't look after Mr White well. Mr White often ate in restaurants. As he never did any cleaning, the rooms were all in a mess(混乱) .

    Yesterday morning, before Mr White got up, the telephone rang. He sat up to answer it. His friend Tony told him to write down an important telephone number. But he could not find a pen or a piece of paper. He found there was much dust(灰尘) on the table and wrote the number on it with his finger. But soon he forgot about it and went to work.

    This morning, Mrs White and their daughter came back home.

    At noon, Mr White came in while Mrs White was cleaning the rooms. He sadly found the table was clean and the number was gone(不见了) .
