to

的用法:“必須、不得不”.haveto表“必須”時與must意義接近，有時可與must互換，但haveto所表示的“必須”更側(cè)重于客觀需要。情態(tài)動詞must通常表示說話人的主觀看法，“必須”。無人稱和數(shù)的變化，不能單獨(dú)使用，必須與其后的動詞原形構(gòu)成謂語。其否定形式為mustn't，“不準(zhǔn)；禁止”。例如：我不得不在家照顧我弟弟。_________________________________孩子們必須6點(diǎn)前回來。__________________________________________Ihavetolookaftermybrotherathome.Thechildrenmustbebackbefore6o’clock.haveto可用在不同時態(tài)中，有人稱和數(shù)的變化。結(jié)構(gòu):1.肯定形式：主語＋have

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

have

to＋動詞原形＋其他doesn'thaveto(一般現(xiàn)在時，單三式)3.疑問句:Do

(Does)＋主語＋have

to

＋動詞原形＋其他?例如：尼克不必穿制服。_________________________________
