虚拟语气用法的详解

来源:101教育网整理 2016-08-18 字体大小: 分享到:

  运用条件句中的虚拟语气时,须注意的几个问题

  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。如:

  Were I ten years younger, I would study abroad. 要是我还年轻十岁的话,我会去国外学习。

  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。

  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。如:

  If I had worked hard at school, I would be an engineer, too. 如果我在学校学习刻苦的话,我现在也会使工程师了

  If they had informed us, we would not come here now. 如果他们通知过我们的话,我们现在就不会来这里了。

  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。如:

  If he were free today, we would have sent him to Beijing. 如果他今天有空的话,我们会已经派他去北京了。

  If he knew her, he would have greeted her. 要是他认识她的话,他肯定会去问候她了。

  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。如:

  If it had not been raining too much, the crops would be growing much better. 如果天不下太多的雨的话,庄家会长得更好。

  If he had been working hard, he would be working in the office now. 要是他工作一直努力的话,他现在已进了办公室了。

  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。如:

  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。

  Were she here, she would agree with us. 如果她在这儿的话,她会同意我们的。

  Had he learnt about computers, we would have hired him to work here. 如果她懂一些电脑知识的话,我们会已经聘用他来这里工作了。

  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。如:

  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。

  But for his help, we would be working now. 要不是他的帮助,我们还会在工作呢。

  Without your instruction, I would not have made such great progress. 要是没有你的指导,我不会取得如此大的进步。
