to

的用法:“必須、不得不”.haveto表“必須”時(shí)與must意義接近，有時(shí)可與must互換，但haveto所表示的“必須”更側(cè)重于客觀需要。情態(tài)動(dòng)詞must通常表示說(shuō)話人的主觀看法，“必須”。無(wú)人稱和數(shù)的變化，不能單獨(dú)使用，必須與其后的動(dòng)詞原形構(gòu)成謂語(yǔ)。其否定形式為mustn't，“不準(zhǔn)；禁止”。haveto可用在不同時(shí)態(tài)中，有人稱和數(shù)的變化。結(jié)構(gòu):1.肯定形式：主語(yǔ)＋have

to＋動(dòng)詞原形＋其他hasto(一般現(xiàn)在時(shí),單三式)2.否定形式:“不必”主語(yǔ)＋don't

have

to＋動(dòng)詞原形＋其他doesn'thaveto(一般現(xiàn)在時(shí)，單三式)3.疑問(wèn)句:Do

(Does)＋主語(yǔ)＋have
