运用条件句中的虚拟语气时,须注意的几个问题
1) 当从句的主语为第三人称单数时,谓语动词若是系动词be时,可用 was 代替 were但在倒装虚拟结构及 if I were you, as it were 中,只能用 were。
If I were you, I would try my best to grasp the chance. 要是我是你的话,我要尽力抓住这次机会。 2) 有时,虚拟条件句中,主、从句的动作若不是同时发生时,须区别对待
①从句的动作与过去事实相反,而主句的动作与现在或现在正在发生的事实不符
If I had worked hard at school, I would be an engineer, too.
②从句的动作与现在事实相反,而主句的动作与过去事实不符
If he were free today, we would have sent him to Beijing.
③从句的动作与过去发生的情况相反,而主句的动作与现在正在发生的情况相反
If it had not been raining too much, the crops would be growing much better.
(3) 当虚拟条件句的谓语动词含有 were, should, had 时,if 可省略,而将 were, should, had等词置于句首
Should he agree to go there, we would send him there. 要是他答应去的话,我们就派他去。
(4) 有时,句子没有直接给出假设情况的条件,而须通过上下文或其他方式来判断
I would have come to see you, but I was too busy. 我本该来看你了,然而我太忙了
(5) 有时,虚拟条件句中,主、从句可以省略其中的一个,来表示说话人的一种强烈的感情。
①省略从句
He would have finished it. 他本该完成了
②省略主句
If I were at home now. 要是我现在在家里该多好啊。
