虚拟语气用于条件句 语气及其种类 语气是一种动词形式 随着说话人的意图的不同 动词需要用不同的语气 英语中有三种语气 1 直陈语气 indicativemood 表示所说的话是一种事实 动词可用各种时态 如 1 ithinkyourapproachiscorrect 我认为你的方法是正确的 2 thesituationcouldstillberemedied 事情还有挽回的余地 3 howmanystepsgothroughfromrawmaterialstoproducts 从原料到成品需要多少工序 2 祈使语气 imperativemood 表示说话人向对方提出请求或命令等 动词用原形 如 1 don tmakeanoise 别出声 2 remembertoe mailme 记得给我发电子邮件 3 虚拟语气 subjunctivemood 虚拟语气是一种特殊的动词形式 用来表示说话人所说的话并不是事实 而是一种假设 愿望 怀疑或推测 如 1 iwishicouldhavesleptlongerthismorning butihadtogetupandcometoclass 我希望今天早上能多睡一会 但我得起来去上课 2 hisdoctorsuggestedthathe should takeshortleaveofabsence 医生建议他休几天假 3 ifheweretoleavetoday hewouldgettherebyfriday 如果他今天出发 星期五前就能到那 虚拟语气用于条件句 条件句有真实条件句和非真实条件句两种 1 真实条件句所表示的假设是可能发生或实现的 句中的条件从句和结果从句皆用直陈语气 如 1 ifihaveenoughmoney iwillbuyacomputer 假若我有钱 我就买台电脑 2 iftheykeeponstealing theywillreapwhattheysow 如果他们继续偷窃 必将自食其果 3 ifyouhavenotfinishedwiththatbook youcankeepitforonemoreday 如果那本书你还没读完 你可以再看一天 2 非真实条件句所表示的假设则是不可能或不大可能发生或实现的 句中的条件从句和结果从句皆需用虚拟语气 与现在事实相反的非真实条件句 虚拟语气用在与现在事实相反的条件句中时 条件从句的谓语用动词的过去式 be的过去式用were 结果主句的谓语should would could might 动词原形 如 1 iamsorryiamverybusynow ifihadtime iwouldcertainlycometoseeyou 很抱歉 我很忙 如果有时间我一定去看你了 2 ifitwerenotfortheirsupport wewouldbeinadifficultsituation 要不是有他们的支持 我的处境会很困难 3 ifplaceswerealike therewouldbelittleneedforgeographers 如果各个地方都一样 就不需要地理学家了 4 ifiwereyou iwouldapplyforthejob 如果我是你 我会申请那份工作 exercise ifhe smoke less he notcough somuch ifi be you i go tohospital ifit be notsnowing we go out doors ifi be you i think differently i help himifhe ask me ifi be abird i be veryhappy smoked wouldnotcough were wouldgo were wouldgo were wouldthink wouldhelp asked were wouldbe 与过去事实相反的非真实条件句 虚拟语气用在与过去事实相反的条件句中时 条件从句的谓语用had 过去分词 结果主句的谓语用should would could might have 过去分词 如 1 ifihadtakenyouradvice iwouldnothavemadesuchamistake 如果当时听了你的话 我就不会犯这样的错误了 2 ifithadnotbeenforyourhelp iwouldnothavefinishedtheworksoeasily 要不是你的帮助 我的工作不会这么容易完成 3 ifwehadknownthebasicprinciples weshouldhavecontrolledtheprocessevenbetter 如果我们知道这些基本原理 我们早就能更好的控制这个工序了 4 iffactshadbeencollectedoneweekearlier weshouldhavehadmoretimetostudythem如个早一个星期收集事实 我们就能有更多的时间研究他们了 exercise ifyou leave alittleearlier you catch thetrain ifi finish thejob i go tothefilmwithyou ifi know hernumber i call her ifhe notlose hismoney he buy thecomputerlastweek ifi know hername i talk withher ifyou get upearlier you reach schoolontime hadleft wouldhavecaught hadfinished wouldhavegone hadknown wouldhavecalled hadnotlost couldhavebought hadknown wouldhavetalked hadgot wouldhavereached 与将来事实相反的非真实条件句 虚拟语气用在与将来事实相反的条件句中时 条件从句的谓语用动词的过去式 be的过去式用were should 动词原形或wereto 动词原形 结果主句的谓语用should would could might 动词原形 如 ifitrainedtomorrow ishouldstayathome 如果明天下雨 我就呆在家里 iftheteacherknewit hewouldbeangry 万一老师知道了这件事 他会生气的 iwouldnotlosecourageevenifishouldfailagain 即使再次失败我也不会气馁 ifimadeamistake ishouldtrytoremedyit 如果我犯了错误 我就会设法补救 ifiweretodoit iwoulddoitanotherway 要是我来做这件事 我会用另一种方式 exercise ifit notrain i go tothecinema ifi have anotherchance i learn howtousecomputer ifit snow thisevening they go out ifi become ayoungmanagain i study harder ifhe come tomorrow i speak tohimaboutit ifshe become morebeautiful she be amodel shouldnotrain wouldgo weretohave wouldlearn weretosnow wouldnotgo weretobecome wouldstudy weretocome wouldspeak shouldbecome wouldbe 动词原形 have 过去分词 动词原形 exercise 1 evenifi have themoney i buy it 2 i try itagainifi be you 3 ifit benot forthewater theplants notlive 4 ifi nothave thatchancetoshowmyability i notbecame thepresidentofthisschool 5 ifit notbe yourhelp i notbecome asuccessfulman had wouldnotbuy wouldtry were werenot wouldnotlive hadnothad wouldnothavebecame hadnotbeen shouldnothavebecame 6 ifyourteacher know thismatternextweek she blame you 7 ifjane receive thisletter she be happy 8 ifthestudents do moreexercisesthey notfail inthisexam 9 ifyou speak loud
