(may/might,can/could,must,should,oughtto)1.may(过去式might)“可能”Theremaybelittlewaterleftinthebottle.Hethoughtitmightbewisetotryhisluckthere.Shemaynotbewaitingforyounow.mightmight注意:

可以用might代替may,以表示说话语气更加不肯定;may表示推测时,不能用于疑问句中.如果在疑问句中出现may,则表示请求许可,意为“可以”.MayIuseyourcellphone?

注意:1)可以用could代替can,以表示语气婉转;could2)表示推断,can不能用于肯定陈述句,但could可以用于肯定陈述句,相当于may/might;

Thisstorycouldbetrue,butIhardlythinkitis.may/might2.can(过去式could)“可能会”

Thatcan’tbetrue.Whatonearthcanthismean?

couldn’t3)can可以用于肯定陈述句,表示一时的情况,意为“有时候会…”;

Ourhouseisonthetopofthehill,andinwinterthewindscanbeprettycold.4)maynot/mightnot意为“可能不”,而cannot/couldnot意为“不可能”、“肯定不”,其语气要比maynot/mightnot强得多.3.must“肯定”、“准是”Youmustbejoking,aren’tyou?注意:1)must表示推测不用于否定句,因为mustnot/mustnever只能表示禁止,意为“不准”、“不可以”;

---MayIwatchTVaftersupper?---No,youmustn’t.(maynot/can’t也可)

Judgingbythesmell,thefoodmustbegood,isn’tit?2)must表示推测不用于疑问句,因为must在疑问句中只能表示“必须”或表示反感“(干吗)偏要…”“硬要”;MustIfinishitbytheendofthisweek?WhymustyouaskmesomanyquestionswhenI’mbusycooking?

3)must表示推测不用于将来.应该用别的句型表示推测“肯定会…”、“准会…”.You’resuretosucceed./Itiscertainthatyouwillsucceed./I’msurethatyou’llsucceed.4.should,oughtto“照说应当”,“想比一定”,“按理应该”Fredshould/oughttobeupnow.Mynewpoemsshould/oughttobeoutinamonthatmost.二.表示必要性,、职责、劝告、建议等(need,must,should,oughtto)

1.need“必需”“需要”;must“必须”---MustIbeherebefore9o’clock?---No,youneedn’t.(不能说:No,youmustn’t.)---NeedIbeherebefore9o’clock?---Yes,youmust.(不能说:Yes,youneed.)注意:1)need作情态动词,不能用于肯定陈述句,在陈述句中,应该用need的实义动词表达.Youn
