含蓄條件句

非真實條件句中的條件從句有時不表出來，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.條件暗含在短語中。如：

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

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

Butforyourhelpwecouldn’thavesucceededintheexperiment.(暗含條件是butforyourhelp)

4.without和butfor構成虛擬。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，虛擬式已變成習慣說法，很難找出其暗含的條件。如：

Youwouldn’tknow.你不會知道。

Iwouldliketocome.我愿意來。

Iwouldn’thavedreamedofit.這是我做夢也不會想到的。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!要是我沒錯過火車就好了.現在過去將來Did/wereHaddoneCould+動詞原形(2)=aslongas常用陳述語氣.如果我們緊密團結就一定能戰勝一切困難.Wecansurelyovercomethesedifficultiesifonlywearecloselyunited.asif/though2.asif/though+Clause現在：過去：將來:did/were(現在)haddone(過去)Shelovesthebabyasifitwereherownson.HespeaksasifhehadbeentotheUnitedStates.
