Ⅰ IF虚拟语气的三种时态是什么

1、提出将来会发生的事：主句：主语＋would/should/might/could＋动词原形；

从句：should＋动词原形/were to＋动词原形；

2、提出现在的条件： 主句：主语＋would/should/might/could＋动词原形；

从句：动词过去式；

例句：If he studied at this school, he would know the enviornment around the school very much.

if的用法

if作为从属连词,可引导条件状语从句、让步状语从句和名词从句。

if引导条件状语从句,从句可为真实条件从句,也可为虚拟条件从句。如为真实条件从句,谓语用陈述语气,表示可能性很大,作“假使”“如果”解,通常用一般现在时代替一般将来时; 如果if从句中用will,表示意愿。

从句如为虚拟条件从句,谓语动词要用虚拟语气,表示可能性不大或与过去事实相反,作“要是,假如”解。可指过去的情况,也可指现在和将来的情况。指将来情况时可用were to或should。在现代口语中,一、三人称后常用was代替were。if引导的虚拟条件句中,助动词were,should,had可以移至主语前,此时if可省略。

if引导的条件从句中可以省略be和主语。

if引导的条件从句,有时后接only以加强其语气,表示说话人非常盼望某人提出的条件能够实现。

if可引导让步状语从句,作“虽然,即使”解,常和even连用。

if可引导名词性从句,作“是否”解,常放在ask, doubt, know, learn, see, wonder等动词后。一般用在口语中,而且不能用于句首。

Ⅱ if虚拟语气的三种时态

1、对现在情况的虚拟

条件从句中谓语动词用一般过去式，主句用“would/should/might/could+动词原形”形式，表示对现在不可能实现情况的假想。

If I were you,I would choose to work in a small town.

如果我是你，我会选择在小城镇工作。（事实上我不是你）

注意：在条件从句中，如果谓语动词是be的形式，不管主语是单数还是复数，书面语中用were,而口语中如果是单数，也可以用was,不过在if I were...中一般用were.

2、对过去情况的虚拟

条件从句中谓语动词用过去完成式，主语用“would/could/should/might+have+动词的过去分词”形式。

If it had not been for your help yesterday,I could not have caught the bus.

如果昨天没有你的帮助，我不会赶上公交车。（事实是你昨天已经帮助了我，所以我赶上了车)

3、对将来情况的虚拟

在表示与将来事实相反的条件从句中，谓语动词可用should do,were to do或动词的过去式三种形式表示，但意义略有不同。should表示的可能性最大，动词过去式的可能性次之，were to do 的可能性最小。

If things were to be twice，all would be wise.

假如凡事都可以重新做一次，人人皆可成为聪明人。（事实是并不是所有的事都可以重新做一次)

注意：在书面语中，如果虚拟条件从句中有were，had 或 should，可以把if省略，把这几个词放到主语之前，构成主谓倒装。

其他条件句：

1、错综时间条件句

有些条件句的主句谓语和从句谓语表示的动作在时间上并不一致，这类句子称为错综时间条件句。

If you had taken my advice then,you would not be in trouble now.

如果当时听我的劝，你现在就不会有麻烦了。(if 条件句是对过去的虚拟，故用过去完成时，而主句是对现在的虚拟，故用“would+动词原形”形式）

2、含蓄条件句

有些句子虽不含条件从句，但意思和条件句相差不多，这种句子称为“含蓄条件句”，这种句子有时候会用虚拟语气。

如: Without air (If there were notair), there would be no living things.

But for your help (If it ha dn'tbeen for your help) I couldn't have don e it.

Ⅲ 表后悔的虚拟语气的时态搭配是什么样的讲清楚点，我只要结构，每个带点例句更好

个人觉得这个讲的还可以
仅供参考，不代表个人观点
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。
时间 从句谓语形式 主句谓语形式

将来 动词过去式(be用were)
should + 动词原形
were to + 动词原形
would / should / might / could + 动词原形
现在 动词过去式(be 用 were) 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
2. 条件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。
If he were to come here, he would tell us about it. 如果他要来的话，他会通知我们一声。
(2) 现在时的条件句中的虚拟语气。如：
If he were free, he would help us. 要是他有空的话，它会帮助我们的。
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) 过去时的条件句中的虚拟语气。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。
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 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。

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。
(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。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。
(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。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。
(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。
You could have passed this exam. 你应该会通过这次考试了。
②省略主句

Ⅳ 求英语倒装句分类及复杂例句！以及三种时态虚拟语气的分别例句！越复杂越好！

倒装句

英语最基本的语序是主语在前，谓语动词在后。但有时由于句子结构的需要或表示强调，就要采用倒装形式。将谓语动词完全移到主语之前称为完全倒装，只将助动词或情态动词放到主语之前称为部分倒装。强调性倒装和以so， neither， nor开头的句子是高考例题的热点。
一、倒装句的意义

1. 适应一定的语法结构的需要，主要是指疑问句句型结构的需要。

e.g. May I come in？

Was the People‘s Liberation Army founded in 1927？

2. 为了强调某一部分，而把这部分放到句首，构成倒装。

e.g. Never have I been late for school this term.

So early did he come to school that no other students came.

二、倒装的使用情况

1. 在“there be”结构里，there是引导词，主语在be后。

e.g. There is a box on the table.

2. 在疑问句中。

e.g. Is she singing in the classroom？

What does your mother do？
3. 在here， there等副词开头的某些句子里（要用一般现在时态）。如果主语是人称代词，主语和主要动词的词序不变。（完全倒装）

e.g. There goes the bell.

Here is an apple for you.

There she comes.

4. 重复倒装句型，用在以so， nor， neither开头，表示谓语所述的情况也适用于另一个人或一事物的肯定或否定句中。so用于肯定句，表示“也一样”“也这样”；nor， neither用于否定句，表示“同样也不，也不这样”。

e.g. I am watching TV. So is she.

My parents didn't watch TV last night. Neither （Nor） did I.
5. 直接引语的全部或一部分放在句首时，主句中的主谓也常直接倒装。（完全倒装）

e.g. "Very well，" said the French student.

"Bring me two eggs and a cup of tea， please." said he.

6. 在以never， little， hardly， not only， few， not， seldom等否定副词开头的句子中，采用部分倒装。如不放在句首就不要倒装。

e.g. Little did he say at the meeting.

Never shall I forget the day when I joined the Army.

比较：I shall never forget the day when I joined the Army.
7. 用于以only所修饰的副词、介词短语或状语从句的句子中。

e.g. Only when the war was over in 1918 was he able to get happily back to wrk.

Only in this way can we learn English well.

注意：如果only后的词组不是状语，不需倒装。

e.g. Only Wang Lili knows this.
8. 为了表达生动，有时把表地点、方位的副词，如 up， down， out， away， in等放在句首，同时把谓语动词放在主语之前。若主语为人称代词，主语和谓语动词的位置不变，只将副词放在句首。（完全倒装）

e.g. Away hurried the boy.

Out rushed the girl.

9. 在虚拟结构中，条件从句的谓语含有were， had 和should这三个词是，可省去if，将这些词移至主语之前。

e.g. Had I time （= If I had time）， I would go and help you.

Were I you （= If I were you）， I would go abroad.

Should he come （=If he should come）， tell him to ring me up.

10. as引导让步状语从句时要倒装（形容词/ 副词/ 名词/ 动词 + as + 主语 + 谓语）。

e.g. Proud as they are， they are afraid to see me.

Child as he is， he seems to know everything.（child前不加冠词）

Hard as he worded， he made little progress.
11. 用于某些表示祝愿的句子里。

e.g. May you succeed！

Long live the People‘s Republic of China！

12. So + 形容词、副词及such 置于句首时要倒装。

So happy did he feel.

Such was me.

Ⅵ 求助虚拟语气各种情况的例句举例和解析~

第一步：掌握对现在，对过去，对将来的虚拟的固定时态
对现在的虚拟：
If he were free, he would help us. 要是他有空的话，它会帮助我们的。
注意，虚拟中的is,都用were
注意，主句用would +动词原型，从句用过去式
对过去的虚拟
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
注意时态：主句用would +现在完成时，从句用过去完成时
对将来的虚拟
If he were to come here, he would tell us about it.
如果他要来的话，他会通知我们一声。
或，if he came here...
if he should come here....
主句用would +动词原型，从句分三种：过去式，were to,should
第二步：掌握错综虚拟，即主从句的动作（看时态提示词），有错综

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。
本来主句用了would +现在完成时，说明是对过去的虚拟，从句本来应该用过去完成时，但是，由于从句中有个时态提示词，today,则套用对现在的虚拟的公式，用过去式
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。
从句用了过去完成时，说明死对过去的虚拟，本来主句要用would +现在完成时，可是，主句里有个时态提示词，now,则主句套用现在的虚拟，用would +动词原型
这样根据主句，从句不同的时态，针对不同时间的虚拟，叫错综虚拟

第三步，含蓄虚拟语气，就是把if 省略，用倒装
Were she here, she would agree with us. 如果她在这儿的话，她会同意我们的。
=if she were here,she would agree with us
第四步，虚拟语气再名词性从句中的应用
对于表建议，命令，要求的词，虚拟比较固定，一律用should +动词原型，但是should 可以省略

advise, ask, demand, desire, decide, insist(坚决要求) , order,
propose, request, suggest(建议) 表示请求、要求、命令或建议等意义的动词所接的宾语从句一般用虚拟语气，其虚拟语气的结构为：(should) + 原形动词。如：
The teacher advised that we （should） make good use of every minute here.
老师劝我们要好好地利用在这儿的每一分钟。

Ⅶ 如何辨别虚拟语气中的三种时态

1、对现在的虚拟结构：if+主语+动词动词过去时，主语+should/would+动词原形 ，should不可以省略。

【例句】If I had had enough money, I would have joined the swimming club.

【翻译】如果我有足够的钱，我就能去参加游泳俱乐部了。

2 、对过去的虚拟结构：if+主语+had+过去分词，主语+should/would+have+动词过去时。

【例句】If she had told him about the danger, he would not have got hurt.

【翻译】如果她能早点告诉他危险，他就不会受伤了。

3 、对将来的虚拟结构：if+主语+should+动词原形（were to+动词原形），主语+would/should+动词原形，这个should可以省略。

【例句】If he had followed my advice, he would not suffer so much now.

【翻译】如果他当初听我的意见，现在就不会受那么多的罪了。

Ⅷ 给你一个句子，如何辨别虚拟语气中的三种时态，请举例子

一、与现在事实相反
若与现在事实相反，虚拟语气的条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如：
If you took a taxi，you'd get there quicker. 如果你坐出租车去，你可以快一点到那里。(但你不坐)
If I knew her number I could ring her up. 要是我知道她的电话号码，我就可以给她打电话了。(可惜我不知道)
二、与过去事实相反
若与过去事实相反，虚拟语气的条件从句的谓语用过去完成时(had+过去分词)，主句谓语用“should (would, could, might)+have+过去分词”。如：
If I'd left sooner，I'd have been on time. 要是我早点动身，我就准时到了。(但我动身太迟了)
If we had found him earlier we could have saved his life. 要是我们当时早点找到他的话，我们就可以救活他。(可惜我们找到他太晚了)
三、与将来事实相反
若与将来事实相反，条件从句的谓语用过去式(be通常用were)，主句谓语用“should (would, could, might)+动词原形”。如：

Ⅸ 虚拟语气的的三种情况下主句从句各用什么时态并写一个例句

在for
fear
that，in
case，lest引导的从句中，若用虚拟语气时，从句谓语为：（should）
+
do。并且should能省略（for
fear
that，lest），in
case不能省略
