一、 If 引导的非真实条件句

1. 知识基础表格释义
从句中提出一种与客观现实不相符或根本不可能存在的条件,主句会产生的一种不可能获得的结果。条件句中的 虚拟语气根据不同的时间有三种不同的形式。 时间 从句谓语形式 动词过去式(be 用 were) 将来 should + 动词原形 were to + 动词原形 现在

动词过去式(be 用 were) would / should / might / could + 动词原 形 would / should / might / could + 动词原 形 过去 had +动词过去分词 would / should / might / could have + 动 词过去分词 例句如下: If he should go to Qing Hua University, he would make full use of his time. 如果他要上清华大学的话, 他就会 充分利用他的时间了。(将来) If he studied at this school, he would know you well. 如果他在这所学校学习的话,它会对你很熟悉。(现在) If I had got there earlier, I would have met Mr. Li. 如果我早点到那儿,我就会会到了李先生。(过去) 2. 高考考点提示 ① 错综条件句 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。主句从句的结构应分别考虑。 If I had worked hard at school, I would be an engineer now. 如果我在校刻苦的话,我现在应是工程师了。 从句与过去事实相反 主句与现在事实相反 主句谓语形式

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。 从句与现在事实相反 ② 条件句中的倒装 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(from www.yygrammar.com)。 主句与过去事实相反

③ 含蓄条件句 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。常见的特征词有 but,but for,wi thout,or 和 otherwise。例句如下: 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。 You instructed me, or I would not have made such great progress. 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。 Given more attention, the tree could have grown better. 如果多留心的话,这树本来可以长的更好。(MET 1990) (-ed 分词做条件状语,暗示: If the tree had been given more attention) 二、虚拟语气的其它情况
