一、什么叫錯(cuò)綜時(shí)間虛擬條件句

　　所謂錯(cuò)綜時(shí)間虛擬條件句即條件從句與主句所指時(shí)間不一致，如從句指過(guò)去，而主句即指的是現(xiàn)在或?qū)��?lái)，此時(shí)應(yīng)根據(jù)具體的語(yǔ)境情況，結(jié)合上面提到的三種基本類型對(duì)時(shí)態(tài)作相應(yīng)的調(diào)整：

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

　　You would be much better now if you had taken my advice. 假若你當(dāng)時(shí)聽(tīng)我的話，你現(xiàn)在就會(huì)好多了。

　　二、一點(diǎn)特別說(shuō)明

　　條件從句用 if I were…時(shí)，既可指現(xiàn)在也可指過(guò)去：

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

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

　　If I were not busy, I would have come. 假若我不忙，我早就來(lái)了。

　　也可用 if I had been you也表示過(guò)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。
