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