to

should

GrammarModalverbs情态动词(二)should和oughtto都为“应该”意思，可用于各种人称。oughtto语气稍重一些。他们想必已到那儿了。Theyoughttobetherebynow.他最好不要抽烟了。Heought

tostopsmoking.

1.oughtto/shouldshould表示主语义务或责任：

Youshouldtakecareofyoursister．你应该去照料你妹妹。或指出一个正确、明智动作：

Theyshouldn’tallowparkinghere;thestreetistoonarrow．这儿不该允许停车;马路太窄了。should和oughtto后面跟动词不定式完成式,其必定句表示“过去应该做而未做”,其否定句则表示“过去不该做但做了”。Youshould/oughttohavemadethedecisionaweekago.Ishouldn't

havemadesuchafoolishmistake.多数情况下,oughtto可与should交换使用。oughtto反意疑问句用shouldn’t替换。注意YououghttohavehelpedhimwithhisEnglish,____you?A.won’tyouB.oughtnotyouC.shouldn’tyouD.wouldn’tyouC三者均表示提议,意为“应该”,“应该”或“最好做……”。三者语气程度为渐强。hadbetter指普通性提议,最弱。should&ought

to含义相近,常可交换。区分在于,ought

to常指特殊情况下“应该”。Should则指普通情况。如：had

better,should&oughttoShall用于第一,三人称疑问句中,表征求意见或请求;用于第二,三人称陈说句中,表命令,警告,允诺,威胁等;should

表劝说,提议,命令,顺理成章,和oughtto一样。疑问句中惯用should代替oughtto。ought

to

表应该,语气比should强。shall,should&oughttoYououghttohelphimbecauseheisintroublenow.(语气强,有命令意味)Youshouldhavearestafterfinishingyoursports.(普通性提议)Youought

tocallthepolicewhenyoufindsomethingwronginyourhouse.Heshouldtakecareofthebabiestonight.

haveto表示客观需要去做事情,

意为“必须,不得不”。Ihavetogetthestationearlytocatchthefirsttrain.Wemissedthebussowehadtowalkhome.Wehave

toovercomeallkindsofdifficulties.2.have

tohaveto有各种时态:Wewillhavetogatherattheschoolgateat7tomorrow.普通未来时Ihave

totakemoremoneywithmebecausemygirlfriendhassomuchtobuy.普通现在时Finally,wehad

togiveupourideatoholdapicnicoutsideasitrainedforawholeafternoon.普通过去时--Musttheydotheirhomeworknow?--Yes,theymust.--No,theyneedn’t/don’thaveto.

must用于疑问句问询对方是否定为主语必须做某事;必定回答能够用must,否定回答不能用mustn’t,惯用don’t

have

to

或needn’t。musthaveto主观／客观主观客观时态现在,未来各种表推测√×问询意愿√×否定意思禁止,不允许无须must&have

toneed用于否定句、疑问句或条件句中，needn’t表示“没必要”,needn’thavedone表示过去原来无须做而实际上做了事。3.need注意对need问句回答:--NeedIfinishtheworktoday?--Yes,________________.No,________________.No,________________.youmustyouneedn’tyoudon’thaveto用以下图片造句。做适当运动Youshoulddosomesports.慢慢地进食,并有助消化。Youought
