的用法:“必须、不得不”.haveto表“必须”时与must意义接近，有时可与must互换，但haveto所表示的“必须”更侧重于客观需要。情态动词must通常表示说话人的主观看法，“必须”。无人称和数的变化，不能单独使用，必须与其后的动词原形构成谓语。其否定形式为mustn't，“不准；禁止”。haveto可用在不同时态中，有人称和数的变化。结构:1.肯定形式：主语＋have

to＋动词原形＋其他hasto(一般现在时,单三式)2.否定形式:“不必”主语＋don't

have

to＋动词原形＋其他doesn'thaveto(一般现在时，单三式)3.疑问句:Do

(Does)＋主语＋have
