e.g. You mustn’t shout in public.
注意: 不用mustn’t 来回答由must（必须、一定要）开头的问句, 而应用needn’t (don’t have to)。Grammar focuse.g. ---- Must we hand in our exercise books today?
---- Yes, you must.
---- No, you don’t have to / you needn’t. May
表示请求和允许。might比 may语气更委婉，而不是过去式。否定回答时可用can’t 或mustn’t，表示“不可以，禁止”。
----Might/ May I smoke in this room?
---- No, you mustn’t.
---- May/Might I take this book out of the room?
---- Yes, you can. (No, you can’t / mustn’t. ) 用May I...？征徇对方许可时比较正式和客气，而用Can I...？在口语中更常见。
