思馬得英語100個(gè)句子學(xué)英語語法（38）：虛擬語氣在條件句中的用法

　　<例句>

　　If you had taken her advice, you wouldn't be in such trouble now.

　　如果你聽了她的勸告，你現(xiàn)在就不會(huì)有這種麻煩了。

　　有些條件句主句謂語和從句謂語表示的動(dòng)作在時(shí)間上并不一致，這類句子成為錯(cuò)綜時(shí)間條件句。還有些句子雖不含條件句，但意思和條件句差不多，這類句子成為含蓄條件句，在這種句子中，也可能需用虛擬語氣。某些情態(tài)動(dòng)詞在口語里使用得很多，可以使語氣變得委婉。
