虚拟语气;一、虚拟语气用在if引导的条件状语从句;Iwouldbuyanexpensivecar.

Iwouldbuyavilla.

Iwouldtravelaroundtheworld.

;IfI____________timelastnight,

I_____________toseethefilmwithyou.;Mark:100;PRACTICE1:Fillintheblanks.

a.Ifthey______(be)here,they__________(take)youradvice.

b.Iftheworld-war___________(break)outagain,what________________(happen)toourpeopleonearth?

c.IfI_______(be)inyourposition,I_____________(ask)forteacher’shelp.;注意1:省略if的虚拟条件句，必须把if从句中的were/should/had位于句首，即采用局部倒装。

IfIweretomeethimtomorrow,Ishouldaskhimaboutit.

Ifheshouldfailintheexperimentthistime,hewouldtryagain.

Ifhehadworkedharder,hewouldhavepassedthefinalexaminations.

;二．含蓄虚拟条件句

有时候假设的情况不以if引导的条件从句形式表现出来，而是通过一个介词或介词短语表示。常用的词或短语有：without〔要是没有，如果不是〕,butfor(要是没有)。

与现在事实相反，句子谓语用would/could/might+V-原形〔注：不用should〕

与过去事实相反，句子谓语用would/could/might+havedone

Eg:Withoutelectricity,humanlifewouldbequitedifficulttoday.=Iftherewerenoelectricity,

Withouthisadvice,Icouldn’thavedoneitallbymyself.=Ifithadn’tbeenforhisadvice,

Butforyourhelp,Iwouldn’thavesucceededindoingthisexperiment.=Ifithadn’tbeenforyourhelp,

Butforthemeeting,IwouldhavegonetoyourpartylastSaturday.

=Ifithadn’tbeenforthemeeting,;;三.在ifitwere(hadbeen)notfor….句型中的虚拟语气，意为‘要不是由于…’。

ifitwerenotfor….与现在事实相反，主句用would/could/should/might+V-原

Ifithadnotbeenfor….与过去事实相反，主句用would/could/should/might+havedone

例子：

Ifitwerenotforpeace,wecouldnotbelivingahappylifetoday.

Ifithadnotbeenforyourtimelyhelp,Iwouldhavegonebankrupt.

;四．虚拟语气在宾语从句的应用

1.wish后面所跟宾语从句，从句谓语动词用虚拟语气〔意为要是，但愿…就好了〕。;IwishIwereastallasyou.

IwishIbecameasfamousasYaoMing.

;Hewishhehadn’t
