      1.虛擬語氣在條件句中的用法現在事實相反的假設

      (1)若表示與,則條件從句中用過去式,主句中用過去將來式(would,should,could,might+動詞原形);

      (2)若表示某事將來實現的可能性不大,則條件從句中用should+動詞原形也可用“wereto+動詞原形”或用過去式動詞。如:

      IwouldcertainlygoifI___________(have)time.(現在)

      Ifitshouldrain,wewouldn''''tgoout.(將來)

      (3)若表示與過去事實相反的假設,從句中用過去完成式,主句中用過去將來完成式(should,would,could,might+have+過去分詞)。如:

      IfIhadsetoffalittleearlier,I____________________caughtthetrain.

      Shewould/mighthavecomeifshe__________beensobusy.

      IfIhadn''''t___________(take)youradvice,Iwouldhavemadeabadmistake.

      (4)含有虛擬語氣的條件狀語從句中,如有had,should,were這三個詞的話,在正式或書面語言中可將if省略,再將句子的主語和謂語動詞實行全部倒裝或部分倒裝。如:

      ___________theytime(=Iftheyhadtime),theywouldcertainlycomeandhelpus.

      ____________itbefine(=Ifitshouldbefine),wewouldgoforanouting.

      ___________Iyou(=IfIwereyou),Iwouldgo.

      (4)若主句從句所指的時間不一致,即條件從句表示與過去事實相反,主句表示與現在事實相反;或者條件從句表示與現在事實相反,主句表真實情況,則從句中應采用與具體時間相對應的虛擬形式。如:

      Ifit__________rainedlastnight(過去),Itwouldbeverycoldtoday(現在).

      IfI_____takenyouradvice(過去),Ishouldhavenotroublewiththeworknow(現在).

      2.虛擬語氣在賓語從句中的用法

      在動詞suggest,order,demand,propose,request,command,insist等后的賓語從句中,用虛擬語氣(即Should+動詞原形或只用動詞原形)來表示愿望、建議、命令、請求等。在動詞wish/wouldrather后的賓語從句中,用過去式表示與現在事實不符,用過去完成式表示與過去事實不符。如:

      Isuggestthatwe(should)setoffatonce.

      Thedoctorinsistedthatthepatient(should)beX-rayed.

      IwishI____________asstrongasyou.

      3.虛擬語氣在主語從句中的用法

      在Itisnecessary/important/strange/natural;Itisrequested/suggested/desired/proposed;itisapity等結構后的主語從句中要用虛擬語氣,即Should+動詞原形或只用動詞原形。如:

      Itisnecessarythathe(should)besentthereatonce.

      ItisrequestedthatProfessorLi(___________)giveusaspeech.

      Itisdesiredthatwe(should)geteverythingreadybytonight.

      4.虛擬語氣在表語從句、同位語從句中的用法。

      在suggestion,proposal,idea,plan,order,advice等名詞后的表語從句、同位語從句中要用虛擬語氣,即should+動詞原形或只用動詞原形。如:

      Oursuggestionisthatyou(should)bethefirsttogo.

      Myadviceisthatwe(____________)sendforDoctorLi.

      Doyouknowtheorderthatyou(should)keepwatch?

      5.虛擬語氣在其他狀語從句中的用法

      在asif引導的狀語從句中,用過去式表示與現在事實不符,用過去完成式表示與過去事實不符;

      在sothat,inorderthat引導的狀語從句中,常用should/would/could/might+動詞原形來表示虛擬語氣。如:

      Theytalkedasifthey__________________friendsforyears.
