【单选题】
(B) Editor :Today our topic is part-time jobs. Are they good for school children or not? Headmaster : 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. White : I agree. I know school hours are short, but there is homework, too. Children need a lot of sleep. Mrs. White : Young children perhaps, but some boys stay at school until they’re eighteen or nineteen. A part-time job can’t do harm to them. In fact, it is good for them. They get their pocket money. If the pupils from poor families don’t take part-time jobs, they can’t stay at school. Businessman : I think so. Part-time jobs can help the students from poor families and can make the students from rich families know that it is not easy to make money. Editor : Well, two of you agree and two don’t. what do our readers think? 36、The headmaster thinks that students ________ .
