must和must not的区别

must是肯定一般是'must be’句型

must not是禁止,一般是命令的语气,用于祈使句。是'must not do sth'

注意:must一般是用于肯定句,除非是其实句。一般否定都用can't。'i can't do this thing'

must 和must not ,have to 和not have to ,need和not need有什么区别

must must not:前者是必须的意思,后者是不应该,不允许的意思 have to not have to:前者是不得不(去做某件事的意思,后者是不是不得不(去做某件事) need not need :前者是需要(某物或做某件事),后者是不需要,即不是必要(做某件事)

请问must、must not、have to、 not have to的用法是?

must必须,也可以表作推测,例如,he must have the tool,表推测,肯定的意思

must not,禁止,不允许,也可以表作推测的否定意义

have to,have to do sth,不得不去做某事,如,I have to go to the school.

not have to ,并不一定要做某事,如You don't have to choose one, you can buy all of them.
