一、什么叫錯綜時間虛擬條件句

　　所謂錯綜時間虛擬條件句即條件從句與主句所指時間不一致，如從句指過去，而主句即指的是現(xiàn)在或將來，此時應根據(jù)具體的語境情況，結合上面提到的三種基本類型對時態(tài)作相應的調(diào)整：

　　If it had rained last night, the ground would be wet now. 要是昨晚下過雨的話，現(xiàn)在地面就會是濕的。

　　You would be much better now if you had taken my advice. 假若你當時聽我的話，你現(xiàn)在就會好多了。

　　二、一點特別說明

　　條件從句用 if I were…時，既可指現(xiàn)在也可指過去：

　　If I were you, I would stay. 我要是你我就會留下。

　　If I were you, I’d go to night school. 我要是你，我會上夜校。

　　If I were not busy, I would have come. 假若我不忙，我早就來了。

　　也可用 if I had been you也表示過去：

　　If I had been you，I’d have taken the job. 我要是你，我就接受那份工作了。
