1.虛擬語氣在條件句中的用法現(xiàn)在事實(shí)相反的假設(shè)

(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(dòng)詞原形）；

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

IwouldcertainlygoifI___________(have)time．（現(xiàn)在）

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

（3）若表示與過去事實(shí)相反的假設(shè)，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．

（4）含有虛擬語氣的條件狀語從句中，如有had，should，were這三個(gè)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(dòng)詞實(shí)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(shí)間不一致，即條件從句表示與過去事實(shí)相反，主句表示與現(xiàn)在事實(shí)相反；或者條件從句表示與現(xiàn)在事實(shí)相反，主句表真實(shí)情況，則從句中應(yīng)采用與具體時(shí)間相對(duì)應(yīng)的虛擬形式。如：
