含蓄條件句

非真實(shí)條件句中的條件從句有時(shí)不表出來(lái)，只暗含在上下文中，這種句子叫做含蓄條件句。含蓄條件句大體有三種情況:

1.條件暗含在短語(yǔ)中。如：

WhatwouldIhavedonewithoutyou?(條件暗含在分詞短語(yǔ)withoutyou中)

Itwouldbeeasiertodoitthisway.(條件暗含在不定式短語(yǔ)todoitthisway中)

Butforyourhelpwecouldn’thavesucceededintheexperiment.(暗含條件是butforyourhelp)

4.without和butfor構(gòu)成虛擬。butfor要不是Withoutsunlight,people’slifedifferentfromtoday.Butforyourhelp,Ifinishedthework.Withoutyourhelp,I.Butforwater,itimpossibletoliveinthedesert.wouldbewouldn’thavewouldhavefailedwouldbe2.條件暗含在上下文中。如：

Youmightstayhereforever.(可能暗含ifyouwantedto)

Wewouldhavesucceeded.(可能暗含ifwehadkepttrying)

Yourreputationwouldberuined.

(可能暗含ifyoushouldacceptit)

Iwouldappreciatealittleofyourtime.

(可能暗含ifyouweresokindastogivemealittleofyourtime)

3.在不少情況下，虛擬式已變成習(xí)慣說(shuō)法，很難找出其暗含的條件。如：

Youwouldn’tknow.你不會(huì)知道。

Iwouldliketocome.我愿意來(lái)。

Iwouldn’thavedreamedofit.這是我做夢(mèng)也不會(huì)想到的。IfonlyIfonly(1)…要是就好了=IwishIfonlyIknewhisnamenow!Ifonlywehadfollowedyouradvicelasttime!IfonlyIcouldseehimagainnextyear!要是我們的父母能和我們住在一起就好了。Ifonlyourparentscouldlivewithus!IfonlyIhadn’tmissedthetrain!要是我沒(méi)錯(cuò)過(guò)火車就好了.現(xiàn)在過(guò)去將來(lái)Did/wereHaddoneCould+動(dòng)詞原形(2)=aslongas常用陳述語(yǔ)氣.如果我們緊密團(tuán)結(jié)就一定能戰(zhàn)勝一切困難.Wecansurelyovercomethesedifficultiesifonlywearecloselyunited.asif/though2.asif/though+Clause現(xiàn)在：過(guò)去：將來(lái):did/were(現(xiàn)在)haddone(過(guò)去)Shelovesthebabyasifitwereherownson.HespeaksasifhehadbeentotheUnitedStates.
