上)G、Itisnecessarythatweshouldcleantheroomeveryday,(主語(yǔ)從句虛擬)H、HespeaksEnglishsofluentlyasifhewereEnglish.(特殊從句虛擬)高三英語(yǔ)知識(shí)點(diǎn)3虛擬語(yǔ)氣在一些特殊詞中的使用或含蓄條件句1.wish后的賓語(yǔ)從句。與現(xiàn)在愿望不一致，用主語(yǔ)十過(guò)去時(shí)，例如：Iwi。hIwereyou.與過(guò)去愿望不一致，用主語(yǔ)+had+過(guò)去分詞，例如：IwishIhadvisitedtheWhiteHousewhenIwasintheStates與將來(lái)愿望不一致，用主語(yǔ)+would(could)+原形。2.It'stime句型：當(dāng)lt'stine后用that從句時(shí)應(yīng)該為主i吾+should+動(dòng)詞原形或主語(yǔ)十過(guò)去時(shí)，例如：It，stimethatyouwenttoschool.或It'stimethatyoushouldgotoschooL(2)IfonlyIhadknowntheanswer.我要早知道答案就好了。4.WOuldrather，asif(though)引導(dǎo)的從句也需使用虛擬語(yǔ)氣，表示過(guò)去的情況用過(guò)去完成時(shí)，表示現(xiàn)在與將來(lái)的情況用過(guò)去時(shí)，例如：(l)I'dratheryoupostedtheletterrightaway.(2)Shelovesthechildrenasiftheywerehers.5.含蓄虛擬條件句含蓄條件句是指句中沒(méi)有明顯的虛擬條件句，而是利用其他手段來(lái)暗示存在虛擬條件。但是這類隱含式虛擬條件句往往都可以轉(zhuǎn)化為if引導(dǎo)的條件句。常用來(lái)表示含蓄虛擬條件的手段有：介詞或介詞短語(yǔ)。如butfor，butthat，without,incaseof,undermorefavorablecondition等。連詞。如sothat,unless,incase,supposing,lest,provided(倘若……)，forfearthat(唯恐)，inorderthat,onconditionthat,ifonly(要是……就好了)等。注意：lest,forfearthat和incase引起的從句中謂語(yǔ)動(dòng)詞多用should+動(dòng)詞原形，但也可以不用虛擬語(yǔ)氣，而用動(dòng)詞的陳述語(yǔ)氣形式。例如：Theforeignteacherspokeslowlyincasewemisunderstoodhim這位外籍教師說(shuō)得很慢以免我們誤解。通過(guò)上下文及內(nèi)在含義，句中往往有but,o
