蒋倩萍回答:
C
对现在事实相反用过去时态
虚拟语气表示一种假设的情况,或一种主观的愿望,即动词所表示的动作或状态并非事实,或不可能实现.英语虚拟语气的形式有下列几种:
一、与现在事实相反
连接词
条件从句
结果从句
If
1.动词过去式(或were)
2.助动词(过去式)+动词原形
Should
Would+动词原形
could
might
Ifhadthetime,JohnwouldmakeatriptoChinatoseetheGreatWall.
IfIwereyou,Iwouldgiveupdrinkingimmediately.
二.与将来事实相反
连接词
条件从句
结果从句
If
1.should+动词原形
2.动词过去式
3、wereto+动词原形
Should
Would+动词原形
could
might
Ifyoushouldlose,whatwouldyoudo?
IfIweretoseehertomorrow,Iwouldtellherthetruth.
Ifyouwenttherenexttime,youwouldseewhatImean.
三、与过去事实相反
连接词
条件从句
结果从句
If
had+过去分词
Should
Would+have+过去分词
could
might
IfI’ddnownthatitwasgoingtorain,Iwouldneverhavegoneforawalkinthecountry.
四、虚拟语气的几种特殊用法
省掉if的条件从句结构:
Hadyouaskedme,Iwouldhavetoldyou.(=Ifyouhadaskedme,…)
2.有时虚拟条件不用条件从句而用不定式、分词、介词、名词、连接词或定语从句来表示,如:
Atruefriendwouldnotdosuchathing.
(=Ifhewereatruefriend,he...)
(=Iftherewerenowater,…)
(=Ifyouhadn’thelpedme,…)
3.有时条件从句中的动作和结果从句中的动作发生的时间不一致,如:
Ifhehadfollowedthedoctor’sadvice,hewouldbequiteallrightnow.
IfIwereyou,Iwouldhavegonehome.
五、虚拟语气的其他用法
1、Suggest,advise等动词之后宾语从句须用虚拟语气,其句子结构如下:
suggest,advise,recommend,demand,
require,insist,urge,request,order,+that…(should)+动词原形
devide,ask,move,propose等
注意:在此结构中that不可省略;should省不省均可.
Hesuggestedthatthey(should)stopsmoking.
上述动词的名词形式出现时,that引导的从句仍用虚拟语气.
Hemadearequestthatthey(should)stopsmoking.
如果that引导的从句所表达的内容是事实,也可用陈述语气.
Heinsiststhatheisright.
2、Itis(was)+necessary,apity等+that引导的从句须用虚拟语气,其句子结构如下:
imperative,advisable,动词完成式
Itis(was)+important,natural,necessary,+that…(should)+
essential,strange,等动词原形
Itisimportantthatyou(should)followthedoctor’sorders.
Itisrightthatyoushouldhavedoneyourhomework.
3、wish的用法
动词过去式或were—与现在事实相反
主语+wish(that)+主语+动词过去完成式—与过去事实相反
助动词过去试+动词原形—与将来事实相反
IwishIwereapopsinger.(=IamsorryIamnotapopsinger..)
IwishIhadneverstoppedteaching.(=IamsorryIstoppedteaching.)
Iwishthey’dletusgetsomesleep.
注意:wish与hope接宾语从句的区别在于:hope表示一般可以实现的希望,宾语从句用陈述语气.wish表示很难或不大可能实现的希望,宾语从句用虚拟语气.试比较:
(1)Wehopetheywillcome,(Wedon’tknowiftheycancome.)
(2)Wewishtheycouldcome,(Weknowtheyarenotcoming.)
4、asif,asthough,would(had)rather(that)引导的从句须用虚拟语气,如:
Heactsasifnothinghadhappened.
Iwouldratheryoudidn’ttellhim.
5、It’s(high)timethat…+动词过去式或should+动词原形,如:
It’stime(that)youhadahaircut.
It’shightime(that)wetooksomeaction.
