2. Fill in: mustn't, needn't or can't.
John, I want you to look after your brother this evening. He 1) mustn't go out and he 2) mustn't forget to do all his homework. You 3) mustn't let him watch TV until he's finished it. He 4) mustn't watch the film either - it starts very late. He 5) needn't have a bath; he had one in the morning. There's a cake in the cupboard but you 6) mustn't/can't eat it all - leave some for your sister. You 7) needn't do the washing-up: I'm going to do it tomorrow. You 8) mustn't make too much noise. We might be quite late home because we 9) can't leave the party tonight until most of the guests have left. And you 10) mustn't go to bed without having a wash and brushing your teeth. But you 11) needn't wait for us.
