2 (3)must not 禁止,不许。
►You must come early tomorrow.
►They must be at home. The light is on.
►You must not tell lies.
注意:must开头的疑问句,其否定回答通常用don’t have to 或needn’t,而不用mustn’t。

—No, you don’t have to/ needn’t.
4. need的用法:(1)情态动词 "需要, 有必要",一般用于否定句或疑问句中。(2)行为动词 "需要, 有必要",可以用于各种句式中。
►You needn’t come here this afternoon.
►You don’t need to go now.
need用法口诀:
实义动词表"需要",后接名、代、不定式。 need后接动名词,主动形式表被动。
情态动词表"需要",没有人称、数之变。 其后直接加动原,多用疑问与否定。
