2013高考英語(yǔ)重點(diǎn)知識(shí)：虛擬語(yǔ)氣

2012-09-27 18:07:42 來(lái)源：中華考試網(wǎng)
 

難點(diǎn)形成原因：

　　1．學(xué)習(xí)過(guò)程太零碎，不系統(tǒng)。

　　2．分不清什么時(shí)候使用，怎么使用。

　　3．一些固定用法記不住。

　　解決辦法：

　　虛擬語(yǔ)氣通過(guò)謂語(yǔ)動(dòng)詞的特殊形式來(lái)表示。由于虛擬語(yǔ)氣表達(dá)的是與事實(shí)相反的行為狀態(tài)，其謂語(yǔ)動(dòng)詞的變化不同于陳述語(yǔ)氣，這也是大家感到困惑和容易出錯(cuò)的地方。做此類(lèi)題目時(shí)，關(guān)鍵要迅速發(fā)現(xiàn)解題信息詞，確定虛擬語(yǔ)氣類(lèi)型，然后按各類(lèi)虛擬語(yǔ)氣的特定表達(dá)方式確定動(dòng)詞的形式。

　　用法講解：

　　虛擬語(yǔ)氣表示說(shuō)的話(huà)不是事實(shí)，或者是不可能發(fā)生的情況，而僅是一種愿望、建議或者與事實(shí)相反的假設(shè)等。一般常用于正式的書(shū)面語(yǔ)中。

　　1．條件從句中的虛擬語(yǔ)氣

典型例句

did／were

混合虛擬

從句與過(guò)去事實(shí)相反

主句與現(xiàn)在事實(shí)相反

had done

would do

It is hard for me to imagine what I would be doing today if I had not fallen in love, at the age of seven, with the Melinda Cox Library in my hometown. (2002上海)

 

　　含蓄虛擬條件句

　　有時(shí)假設(shè)的情況并不以條件從句表示出來(lái)，而是通過(guò)一個(gè)介詞短語(yǔ)或其他方式表示。通常的詞或短語(yǔ)有：without"如果沒(méi)有", but for "要不是", but that, otherwise, or, but等。

　　He hesitated for a moment before kicking the ball, otherwise he would have scored a goal. (2001上海春季)

　　But for my classmates’ help, I would not have finished the work in time.     (2004三級(jí)題)

　　Without heat and sunlight, plants on the earth would not grow well.           ( 2004三級(jí)題)

　　注意：在虛擬條件句中，若有動(dòng)詞were, should或had（+過(guò)去分詞），可以省略if，且把這三個(gè)詞放在主句之前，變成倒裝句。如：

　　What would have happened, had Bob walked farther, as far as the riverbank?     (2001上海)

　　Had I realized you were busy, I wouldn't have bothered you with my questions.     (1996三級(jí)題)

　　Had the weather been good, the children could have gone out for a walk.            (2001三級(jí)題)

　　Had he taken the advice of his friends, he would not have suffered such a heavy loss in his business.      (2004三級(jí)題)
