Host: Hello! I'm Gavin from All Talk 970 FM. Welcome to our program. Today our topic is part-time jobs. Are they good for school children or not?

　　Headmaster (校长) : Certainly not. Children have got two full-time jobs already: growing up and going to school. Part-time jobs make them so tired that they fall asleep in class.

　　Mrs Bttck: I agree. I know school hours are short, but there's homework too, and children need a lot of sleep.

　　Mr Black: Young children perhaps, but some boys stay at school until they're eighteen or nineteen. A part-time job can't harm them. In fact, it's good for them. They themselves earn their pocket-money. And they see something of the world outside school.

　　Businessman: You're quite right. Boys learn a lot from a parttime job. And we mustn't forget that some families need the extra money. If the students don't take part-time jobs, they can't stay at school.
