(关于英语语法的问题,我们是这样认为的:语法不是万能的!而且,要想讲流利的英语,也不是一定要精通语法才行,语法千变万化,每一天都会改变,只要人民改变了说话的习惯,语法也就相应的必须改变了,语法是由人们创造的,而不是由语法家创造的!何况,以英语为母语的人,又有几个是精通语法的呢?当你问他们为什么英语要这么讲时,他们只能告诉你,“我们天生就是这么讲的,That comes naturally!”。我们真的很希望大家最后能达到那样的境界,就是把英语变成一种习惯,这才是学英语的最高境界!希望大家早日突破英语语法关!)

16.3 混合条件句

  主句与从句的动作发生在不同的时间,这时主,从句谓语动词的虚拟语气形式因时间不同而不同,这叫做混合条件句。
  If you had asked him yesterday, you would know what to do now.
  (从句与过去事实相反,主句与现在事实相反。)
  If it had rained last night (过去), it would be very cold today (现在).


16.4 虚拟条件句的倒装

  虚拟条件句的从句部分如果含有were, should, 或had, 可将if省略,再把were, should或had 移到从句句首,实行倒装。
  Were they here now, they could help us.
 =If they were here now, they could help us.
  Had you come earlier, you would have met him
 =If you had come earlier, you would have met him. 
  Should it rain, the crops would be saved.
 =Were it to rain, the crops would be saved.

注意:
  在虚拟语气的从句中,动词'be'的过去时态一律用"were",不用was, 即在从句中be用were代替。
  If I were you, I would go to look for him.
   如果我是你,就会去找他。
  If he were here, everything would be all right.
   如果他在这儿,一切都会好的。

典型例题
 _____ to do the work, I should do it some other day.
A. If were I   B. I were C. Were I D. Was I
  答案C. 在虚拟条件状语中如果有were, should, had这三个词,通常将if省略,主语提前, 变成 were, should, had +主语的形式。但要注意,在虚拟条件状语从句中,省略连词的倒装形式的句首不能用动词的缩略形式。如我们可说 Were I not to do., 而不能说 Weren't I to do.
