結(jié)構(gòu)為：May＋主語(yǔ)＋謂語(yǔ)＋其他。e.g.Mayyouhaveagoodtime.祝你過(guò)得愉快。Mayyousucceed!祝你成功！Mayyoubehappy!祝你開(kāi)心！1、當(dāng)主語(yǔ)是第一人稱(chēng)時(shí)，may引導(dǎo)的一般疑問(wèn)句的否定回答用can’t和mustn’t,表示“不可以”和“禁止”。2、“MayI...?”較正式，語(yǔ)氣上更委婉。口語(yǔ)中可以用“CanI...?”表示請(qǐng)求許可?！癈ouldI...?”也可表示請(qǐng)求許可，語(yǔ)氣比“CanI...?”更委婉。但是，用“CouldI...”提問(wèn)時(shí)，回答要用can.e.g.---CouldIuseyourpen?---Yes,youcan./No,youcan’t.3、may一般不用于反意疑問(wèn)句。

may表示“可能”時(shí)，相當(dāng)于副詞perhaps,maybe1.Hemaybeathomenow.=Perhapsheisathomenow.=Maybeheisathomenow.2.Shemaynotbehappynow.=Perhapssheisnothappynow.=Maybesheisnothappynow.注意：副詞perhaps,maybe無(wú)法做謂語(yǔ)，但是may(not)＋動(dòng)原

當(dāng)句子中已經(jīng)有謂語(yǔ)動(dòng)詞,而我們又要表達(dá)不止一個(gè)動(dòng)作概念時(shí),其余的動(dòng)詞可以使用非謂語(yǔ)形式表達(dá)。動(dòng)詞不定式就是動(dòng)詞的一種非謂語(yǔ)形式,其基本形式是“to+動(dòng)詞原形”。如：（不用抄，了解即可）Hewantstoplayfootballafterclass.他想課后踢足球。Mymotherforgottoturnoffthelightsyesterday.我媽媽昨天忘記關(guān)燈了。注意:（記筆記）動(dòng)詞不定式在句子中不作謂語(yǔ),因此沒(méi)有人稱(chēng)、單復(fù)數(shù)和時(shí)態(tài)的變化。Weoftenuseto-infinitivesaftertheseverbs.

agreechoosedecidehopelearnplanpreparewantlikestartbeginfailwishtryrememberforgetYoumustpromisenottobelateagain.你必須保證不再遲到了。Hedecidednottogohome.他決定不回家了。注意：（記筆記）動(dòng)詞不定式的否定形式是“notto+動(dòng)詞原形”。Idon’tknowwheretofindmykeys.CanyoutellmehowtoworkoutthisMathsproblem?疑問(wèn)詞＋todo，是名詞短語(yǔ)，可以放在句中，做動(dòng)詞的賓語(yǔ)。remembertodosth.記得去做某事rememberdoingsth.記得做過(guò)某事區(qū)分forgettodosth.忘記去做某事

forgetdoingsth.忘記做過(guò)某事e.g.Tom,記得課后和我們一起打籃球。Tom,remembertoplaybasketballwithusafterclass.我記得上個(gè)月寫(xiě)了一封信給你。Irememberedwritingalettertoyoulastmonth.stoptodosth.停下(正在做的)事去做(另一件)事stopdoingsth.停止做(正在做的)事e.g.讓我們停下來(lái)休息一下。
