虚拟语气语法总结表格(精选范文)：1虚拟语气在英语中起到了很重要的作用，用来表示与事实相反、假设、愿望、建议、命令等不真实的情况。

虚拟语气的正确运用可以使我们的语言更加丰富、准确，因此作为一名优秀的学生，我们应该对虚拟语气有所了解并能正确运用。

首先，虚拟语气用于与现在事实相反的情况。

当我们想表达与现在事实相反的虚拟情况时，通常用"should/were to +动词原形"来表示。

例如：“If I were you, I would study harder.”（如果我是你，我会更努力学习。

）其次，虚拟语气用于与过去事实相反的情况。

当我们想表达与过去事实相反的虚拟情况时，通常用"had + 过去分词"来表示。

例如：“If I had seen him, I would have told him thenews.”（如果我见到他，我会告诉他这个消息。

）除了上述两种情况外，虚拟语气还可以用于表达愿望、建议和命令等。

当我们想表达愿望时，可以使用“wish + 主语+过去式”。

例如：“I wish I had more time to travel.”（我希望我有更多时间去旅行。

）当我们想提出建议时，可以使用“suggest +（that）+主语+（should）+动词原形”。

例如：“I suggest that he should take a break.”（我建议他休息一下。

）当我们想表示命令时，可以使用“demand/order +（that）+主语+动词原形”。

虚拟语气用来表示与实际情况相反的情况或者表达主观上的愿望、建议、猜测等。

虚拟语气的用法包括与现在事实相反、与过去事实相反和与将来事实相反三种情况。

1. 与现在事实相反：使用动词的过去式（be动词用were），从句使用would+动词原形。

例如：If I were you，I would choose to study abroad.（如果我是你，我会选择出国留学。

）2. 与过去事实相反：使用“would+have+过去分词”，从句使用“had+过去分词”。

例如：If we had known the answer，we would have told you.（如果我们知道答案，我们早就告诉你了。

）3. 与将来事实相反：使用“would+动词原形”，从句使用“were+to+动词原形”或者“should+动词原形”。

例如：If it were to rain tomorrow，the football match would be postponed.（如果明天下雨，足球比赛就会被推迟。

）二、定语从句定语从句是英语语法中的另一个重要知识点，也是专四考试的重点。

定语从句用来修饰名词，通常放在所修饰名词之后。

引导定语从句的关联词包括that、which、who、whose等。

1. 使用that的情况：当先行词为all、something、nothing、this等不定代词时，或者先行词被形容词最高级修饰时，多用that引导定语从句。

例如：This is the most interesting book that I have ever read.（这是我读过的最有趣的书。

）2. 使用which的情况：当引导词前面有逗号或放在句末时，通常使用which。

虚拟语气一、条件句中的虚拟语气1. 条件句中虚拟语气的形式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。

2. 条件句中的虚拟语气的举例(1) 将来时的条件句中的虚拟语气。

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。

(2) 现在时的条件句中的虚拟语气。

如：If he studied at this school, he would know you well. 如果他在这所学校学习的话，他会对你很熟悉。

(3) 过去时的条件句中的虚拟语气。

如：If I had seen the film, I would have told you about it. 我如果看过这场电影，我会把电影内容告诉你了。

3. 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。

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。

(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。

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。

英语四级考试中的虚拟语气英语四级考试中的虚拟语气虚拟语气在宾语从句中的用法是一个常见的考点，我们着重讲一下宾语从句常使用虚拟语气的几类特殊动词，以及这些动词的用法、构成虚拟语气的用法等。

下面是店铺为大家带来的英语四级考试中的虚拟语气，欢迎阅读。

一、何谓虚拟?在英语中，语气(mood)和时态，语态一样，都是谓语动词的一种形式。

表明说话的目的和意图，虚拟语气即表示说话人主观愿望或纯假设情况，动词需用特殊形式。

例如If I were a boy。

其中谓语动词用were，而不是am, shall, was, have等，是因为说话人为女士，而“我是男人”仅是其假设的语气，故用了一个在现实情况中绝不可能用到的were来表达这一虚拟的情况。

通过在I的后面加were这一词，能得知这是虚拟假设出来的情况。

常见的虚拟有两种：1. 表示非真实假设情况：If If I had left sooner, I could have caught the train。

如果早点出发，我就能赶上火车了。

(但我事实上已经错过了，对过去的假设虚拟)He talks so loud as if I were deaf。

他说话声太响，就像我聋了一样。

(但事实我没聋，对现在的假设虚拟)这种情况虚拟时，只需将谓语动词变本身的时态再变过去。

第一句话中的虚拟，本身为过去时，因此再变过去，即过去完成时。

left变为had left, could catch变为could have caught。

第二句话中，as if I am deaf，需要对现在假设，因此变为as if I were a deaf。

(不用I was deaf，避免与真实情况过去式混淆)类似表示非真实情况的`词还有wish希望， suppose假设， would rather宁愿， but for要不是等。

2. 表示建议、命令、要求等主观意愿：He suggested that a petition (should) be drawn up。

第十三节虚拟语气虚拟语气是谓语动词的一种特殊形式，用来表达假设、主观愿望、猜测、建议、可能或纯粹的空想等非真实情况。

一if非真实条件句中的虚拟语气1.if非真实条件句的基本用法由if引导的非真实条件句表示对现在、过去、将来的事实进行假设时，主句与从句中谓语动The victim would have had a chance to survive if he had been taken to hospital in time.遇难者如果及时送往医院，他本来就有机会活下来的。

（与过去事实相反）If I knew his telephone number,I would tell you.如果我知道他的电话号码，我会告诉你。

（与现在事实相反）If there should be a heavy snow next Sunday,we would not go skating.如果下周日下大雪的话，我们就不去滑冰了。

（表将来）[专四真题] I f there were no subjunctive mood, English ______ much easier to learn.could have been B. would be C. will be D. would have been译文：如果没有虚拟语气，英语学习起来就会更容易了。

分析：本题表示与现在事实相反的假设。

表现与现在事实相反，条件从句用一般过去时，主句使用should(would)+动词原形，故B为答案。

A项could have been 是对过去事实的假设，与从句所表示的现在事实不吻合；C项will be 不可以用于虚拟语气中；D 是与过去事实相反的假设的虚拟语气从句形式。

2.省略if的虚拟条件句的用法在虚拟条件句中，如果从句中含有were, had或should等词时，可将if省去，把were, had 或should等提到主句之前，引起倒装。
