八、虛擬語(yǔ)氣在條件從句(Protasis)中的用法：
條件從句有兩類：（1）真實(shí)條件句；（2）虛擬條件句。如果假設(shè)情況有可能發(fā)生的，就是"真實(shí)條件句"。如：
1. If time permits, we'll go fishing together.
　(如果有時(shí)間的話，我們就一起去釣魚。）
如果假設(shè)的情況與事實(shí)相反，則為"虛擬條件句"。如：
1. If it had rained yesterday, we would have stayed at home.
�。ㄈ绻�昨天下雨的話，我們就會(huì)留在家里。） 
這回我們要談的就是關(guān)于"虛擬條件句"的一些句型。
* 這種句子一般由"從句"（Subordinate Clause)和"主句"(Main Clause)組成。如上
例：
　If it had rained yesterday, we would have stayed at home.
　"If it had rained yesterday" 就是"從句"；"we would have stayed at home" 則為"主句。
* 無論"從句"或"主句"的謂語(yǔ)都要用虛擬語(yǔ)氣。它們所用的動(dòng)詞有三種時(shí)態(tài)(Tenses)，就是：現(xiàn)在時(shí)態(tài)、過去時(shí)態(tài)、將來時(shí)態(tài)。
* 句型：
8.1　與現(xiàn)在事實(shí)相反的假設(shè)(事情的發(fā)生都在同一時(shí)間內(nèi)):
　從句：if + 主語(yǔ) + 動(dòng)詞的過去式(be 用 were) + ……

　(從句動(dòng)詞用 were staying, 主句動(dòng)詞用 let)
