专升本英语条件句中的虚拟语气用法,别说你不知道


从教育中整理出来的英语条件句中虚拟语气的用法供考生参考学习,希望对大家有所帮助。

1.过去时,虚拟语气用法为主句谓语形式would / should / might / could have + 动词过去分词,从句谓语形式had +动词过去分词。
例如: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。

2.现在时,虚拟语气用法为主句谓语形式would / should / might / could + 动词原形,从句谓语形式为动词过去式(be 用 were)。
例如: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。

3.将来时,虚拟语气用法为主句谓语形式would / should / might / could + 动词原形,从句谓语形式为动词过去式(be用were)/should + 动词原形/were to + 动词原形。
例如: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。

4.条件句中运用虚拟语气的特殊情况汇总

(1) 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。

(2) 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。
例如:But for his help, we would be working now. 要不是他的帮助,我们还会在工作呢。

(3)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。
例如: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。

②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。
例如: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。

③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。
例如: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。

(4)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。
例如: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。

(5)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。
例如:Were she here, she would agree with us. 如果她在这儿的话,她会同意我们的。
