◎用法總結(jié):must的用法:1.must是情態(tài)動(dòng)詞,無人稱和數(shù)的變化,也無時(shí)態(tài)變化,后面接動(dòng)詞原形。2.表義務(wù),意為“必須”。如:Youmustfinishtheworkbeforeleaving.你必須在離開前完成工作。3.must表示對(duì)現(xiàn)在狀況或過去狀況的肯定推測(cè)。①對(duì)現(xiàn)在狀況的推測(cè):must+原形動(dòng)詞表示“一定……”。如:Itmustbetrue.這一定是真的。②對(duì)現(xiàn)在正在進(jìn)行的動(dòng)作的推測(cè):mustbe+doing表示“……一定正在……”。如:HemustbewatchingTVnow.他現(xiàn)在一定在看電視。③對(duì)過去或已完成狀況的推測(cè):musthave+過去分詞表示“一定曾經(jīng)/已經(jīng)……”。如:Itmusthaverainedlastnight.昨晚一定下過雨。ShemusthavebeentoParis.她一定去過巴黎?！就卣埂?.must的否定式是在must后面加上not,常縮寫成mustn't,意思是“決不可;千萬不能;務(wù)必不要;禁止”。在對(duì)“MayI...?”作否定回答時(shí)用“No,youmustn't/can't.”。如:Youmustn'ttellherthisnews.你決不能(千萬不要)告訴她這消息。Youmustnotsmokehere.你決不能在這兒抽煙。2.must的疑問式是將must提到主語前。must在問句中意為“必須”時(shí),要注意肯定與否定回答時(shí)的用語。其肯定簡(jiǎn)略答語是Yes,主語+must。若是否定回答,則是No,主語+needn't或don'thaveto。如:—MustIfinishmyhomeworktoday?今天我必須完成我的作業(yè)嗎?—Yes,youmust./No,youneedn't/don'thaveto.對(duì),你必須完成。/不,你不必。對(duì)點(diǎn)自測(cè)用情態(tài)動(dòng)詞的正確形式填空,每空一詞1.Youshoutather,becausesheisonlyatwoyearoldgirl.
