情态动词must与haveto1.must的用法

(1)表示有做某一个动作的必要和义务，它的意思是“必须、应该”。

(2)表示有很大把握的判断或者推测，意思是“一定、准是”。2.

haveto的用法haveto表示客观需要做的事情，意思是“必须，不得不”。(2)haveto有人称、数和时态的变化，其第三人称单数形式为hasto。(3)含有haveto,hasto的句子变疑问句或否定句需分别借助助动词do,does。

(1)haveto后接动词原形，意为“必须做……；不得不做……”。

否定形式是：主语+don’t+haveto+动词原形+其他.（一般现在时，当主语是第三人称单数时，用doesn’thaveto，—般过去式用didn’thaveto)2.
