◎用法總結(jié):1.must和haveto都有“必須;不得不”的含義。must表示說話人的強烈要求,含有“命令;義務(wù)”等含義,側(cè)重說話人的主觀意愿和看法;它沒有時態(tài)和人稱的變化,后跟動詞原形。如:Youmustwaitinline.你必須排隊等候。2.haveto則表示客觀原因“不得不”做某事,側(cè)重于外界因素的限制而“被迫”,一般用來表達客觀的需求。haveto有人稱和數(shù)的變化,第三人稱一般現(xiàn)在時的形式是hasto,一般過去式用hadto。如:Tomhastostayathomebecauseitisraininghardnow.現(xiàn)在正下大雨,湯姆必須待在家里。3.對含must一般疑問句的否定回答,不能用mustn't而要用needn't或don'thaveto。對含有haveto的一般疑問句的回答,要根據(jù)時
