Little Tom likes cartoons (动画片) very much .When the cartoons begin on TV, he does nothing until they’re over. Sometimes he’d rather wait for a long time and go to bed late. In the morning his mother has to wake him up, or he will be late for school.

Yesterday Tom heard there would be an interesting cartoon today. This morning, as soon as he got up, he turned the television, but didn’t receive the programme. He had to have breakfast and then went to school. After school he ran home while his mother was cooking supper in the kitchen (厨房). He hurried to the sitting room and turned on the television again, but he couldn’t find the cartoon. He rushed into the kitchen and asked his mother to help.
