     Fred is a sports fan(迷). He likes all kinds of sports games. He never plays football, but he knows

much about it. When there is a football game on TV, he watches it. Sometimes he does not go to school.

    One day, there are two games on TV. One is at 8:00 in the morning, and the other begins at two in the

afternoon. Fred decides to stay at home for the whole day.

    At 7:30, Fred's mother comes to Fred. She sees him still in bed.

    "Is there anything wrong with you?"she asks.

    "I am not feeling well,"Fred answers.

    "Shall I take you to the doctor?" she asks.

    "No. Don't worry, Mum. I will be OK soon,"says Fred.

    "Then I'll go to work. My students are waiting for me,"she says, "If you really feel bad, do call me.

OK?"
