◎用法总结:must的用法:1.must是情态动词,无人称和数的变化,也无时态变化,后面接动词原形。2.表义务,意为“必须”。如:Youmustfinishtheworkbeforeleaving.你必须在离开前完成工作。3.must表示对现在状况或过去状况的肯定推测。①对现在状况的推测:must+原形动词表示“一定……”。如:Itmustbetrue.这一定是真的。②对现在正在进行的动作的推测:mustbe+doing表示“……一定正在……”。如:HemustbewatchingTVnow.他现在一定在看电视。③对过去或已完成状况的推测:musthave+过去分词表示“一定曾经/已经……”。如:Itmusthaverainedlastnight.昨晚一定下过雨。ShemusthavebeentoParis.她一定去过巴黎。【拓展】1.must的否定式是在must后面加上not,常缩写成mustn't,意思是“决不可;千万不能;务必不要;禁止”。在对“MayI...?”作否定回答时用“No,youmustn't/can't.”。如:Youmustn'ttellherthisnews.你决不能(千万不要)告诉她这消息。Youmustnotsmokehere.你决不能在这儿抽烟。2.must的疑问式是将must提到主语前。must在问句中意为“必须”时,要注意肯定与否定回答时的用语。其肯定简略答语是Yes,主语+must。若是否定回答,则是No,主语+needn't或don'thaveto。如:—MustIfinishmyhomeworktoday?今天我必须完成我的作业吗?—Yes,youmust./No,youneedn't/don'thaveto.对,你必须完成。/不,你不必。对点自测用情态动词的正确形式填空,每空一词1.Youshoutather,becausesheisonlyatwoyearoldgirl.
