虚拟语气
l虚拟语气的使用范围及判断
一虚拟语气表示一种不能实现的假设.该语法主要用于if条件状语从句.也可用于主语从句、表语从句、宾语从句等.
二if条件状语从句中虚拟语气的判断
If条件状语从句有真实条件句和非真实条件句.假设条件可以实现的句子为真实条件句(如在阴天说ifitrains,wewouldnotgoout),反之为非真实条件句,要用虚拟语气.
三假设条件一般为:
1)与过去事实相反,从句谓语动词用过去完成时,主句动词为情态动词+完成时态.
e.g.IfIhadcomehereyesterday,Iwouldhaveseenhim.
2)与现在事实相反,从句谓语动词用一般过去时,主句动词为情态动词+动词原形.
e.g.IfIwereateacher,Iwouldbestrictwithmystudents.
3)与将来事实可能相反,从句谓语动词用过去将来时,主句动词为情态动词+动词原形.
e.g.Ifitshouldsnowtomorrow,theycouldn’tgoout.
主句谓语动词为情态动词(should,would,could)+和相应的从句一致的动词形式.
四if条件句中如果有were,should,had,可以省去if,并使用倒装句序.
l宾语从句中的虚拟语气
一wish后面宾语从句中的虚拟语气:根据从句的意义来判断:
1.与现在和将来相反的事实,从句谓语动词用过去时态;
e.g.IwishIwereabird.
2.与过去相反的事实,从句谓语动词用过去完成时态.
e.g.Iwishedhehadn’tdonethat.
二表示“要求、建议、命令”等动词后面的宾语从句中的虚拟语气
从句用“should+动词原形”构成.而且should可以省去.用于此结构的动词有:advise,direct,agree,ask,demand,decide,desire,insist,order,prefer,propose,request,suggest等.
e.g.Iinsistedthathe(should)gowiththem.
Hesuggestthatameeting(should)beheldtodiscussthematter.
HedemandedthatI(should)helphim.
注意:当insist表示“坚持认为”、suggest表示“表明,显示”时,不用虚拟语气.
e.g.Heinsistedthathewashonest.
ThelookonhisfacesuggestedthathewasquitesatisfiedwithwhatIhaddoneforhim.
三wouldrather+从句
在这种结构中,从句的谓语动词用过去形式表示虚拟.
e.g.Iwouldratheryoudidthisinsteadofme.
l主语从句中的虚拟语气
一Itbe+形容词+that….(should)….
用于该句型的形容词有:necessary,good,important,right,wrong,better,natural,proper,funny,strange,surprising,etc.
e.g.Itisnecessarythatweshouldgeteverythingreadybytheendoftheweek.
It’snaturalthatheshouldfeelhurt.
一些名词也可用于此结构中,如apity,nowonder,…..
二Itbe+过去分词+that……(should)……
用于该结构中的过去分词是表示“建议、请求、命令”等词的过去分词.如:desired,suggested,requested,ordered,proposed等.
e.g.Itisdesiredthatthebuildingofthehousebecompletednextmonth.
三Itistime(abouttime/hightime)that…..(过去时动词形式或should+动词原形)…..
e.g.ItishightimeIwenthomenow=ItishightimeIshouldgohomenow.
l表语从句、同位语从句中的虚拟语气
在suggestion,proposal,order,plan,idea,advice,decision等需要具体内容解释的名词后的表语从句、同位语从句中,要使用虚拟语气、其谓语动词为:should+动词原形.连接从句的that不能省略.
e.g.Mysuggestionisthatweshouldgothereatonce.
WhatdoyouthinkofhisproposalthatweshouldputonaplayattheEnglishevening?
TheproposalthatweshouldstaylongerinShanghaiwasrejected.
