注意：1，條件從句的謂語動詞為be時，不管其主語為單數(shù)還是復(fù)數(shù)通常都用were，但在口語或非正式文體中的單數(shù)第一人稱和第三人稱后，也可用was，不過在IfIwereyou這樣的表達(dá)中，通常還是以用were為宜。Ifhehadlearntaboutcomputers,wewouldhavehiredhimtoworkhere.Hadhelearntaboutcomputers,wewouldhavehiredhimtoworkhere.Ifshewerehere,shewouldagreewithusWereshehere,shewouldagreewithus含蓄虛擬語氣有時假設(shè)的情況并不用條件從句表達(dá)，而是由otherwise,but,or,without,butfor等來引導(dǎo)。Iwasillthatday.Otherwise,Iwouldhavetakenpartinthesportsmeeting.(副詞)我那天病了。否則，我就參加運動會了。Hetelephonedtoinformmeofyourbirthday,orIwouldhaveknownnothingaboutit.(連詞)他打電話告訴我你的生日，否則我對此一無所知。Withoutyourhelp,wecouldn'thavefinishedtheworkaheadoftime.＝

Ifithadnotbeenforyourhelp,wecouldn'thavefinishedtheworkaheadoftime.＝

Haditnotbeenforyourhelp,wecouldn'thavefinishedtheworkaheadoftime.沒有你的幫助，我們不可能提前完成這項工作。如：Withoutyourhelp，Iwouldhavefailed.沒有你的幫助，我當(dāng)時就會失敗的。Butforthestorm，weshouldhavearrivedearlier.要不是暴雨，我們還會早到一些。Withherhelp，Iwoulddotheexperimentbetter.在她的幫助下，我就會把實驗做得更好。Onlyforyourhelp，Iwouldhavefailed.若不是你的幫助，我早就失敗了。虛擬語氣在從句的用法一，wish后的賓語從句1.與現(xiàn)在事實相反------一般過去時及（be的過去式為were）2.與過去事實相反-------過去完成時:（had+過去分詞）3.與將來事實相反--------would/could+動詞原形1.Iwish_____________________________(他再試一次)hewouldtryagain2.Iwish____________________(和你一樣年輕)Iwereasyoungasyou3.Iwish__________________________(我看過這部電影)Ihadseenthatfilm4.Iwish_____________________________(我將來當(dāng)個醫(yī)生)Iwouldbecomeadoctor注意：insist作“力言、堅持說”解時，賓語從句不用虛擬語氣，只有當(dāng)insist作“堅持(應(yīng)該)”“堅持(要求)”解時賓語從句才用虛擬語氣。如：Heinsistedthatshewasinnocentandthatshe(should)besetfree.三，Itissuggested/requested/desired/proposed/….that…后接主語從句時advice,desire,order,plan,,recommendation,request,requirement,suggestion,wish充當(dāng)句子的主語后接同位語從句，或表語從句時從句中都用(should)+do四，asif(though)從句用虛擬語氣與現(xiàn)在事實相反——一般過去時；與過去事實相反——過去完成時；表示將來的可能性不大——would(might,could)+動詞原形：Iloveyouasif_____________(你是我兒子)youweremyson.
