高中英語虛擬語氣講解及練習(xí)和答案

1、虛擬語氣虛擬條件句就是對現(xiàn)實(shí)條件的一種虛擬假設(shè)，所假設(shè)的條件一般不符合事實(shí)或與事實(shí)相反或在現(xiàn)實(shí)中發(fā)生的可能性極小。根據(jù)時(shí)間的不同，虛擬條件句可分為三種，即與現(xiàn)在事實(shí)相反的虛擬條件句、與過去事實(shí)相反的虛擬條件句及與將來事實(shí)相反的虛擬條件句。具體情況請看下表：條件狀語從句主句與過去事實(shí)相反had過去分詞shouldwouldcouldmighthave過去分詞與現(xiàn)在事實(shí)相反一般過去時(shí)(be用were)wouldshouldcouldmigh

5、表現(xiàn)出來，而是通過某個介詞或介詞短語（如：with，otherwise，without，butf，inthatposition）、上下文或其它方式表現(xiàn)出來。這種句子稱為含蓄條件句。例如：Butfthehelpfromyou，Iwouldnothavehadthechancetogotocollege.二、虛擬語氣在某些從句中的運(yùn)用在某些詞或短語后接的從句中要使用虛擬語氣，表示愿望、建議或命令等。根據(jù)虛擬語氣的形式不同，虛擬語氣可以分為“
