虛擬語氣三種時態造句

Ⅰ IF虛擬語氣的三種時態是什麼

1、提出將來會發生的事：主句：主語＋would/should/might/could＋動詞原形；

從句：should＋動詞原形/were to＋動詞原形；

2、提出現在的條件： 主句：主語＋would/should/might/could＋動詞原形；

從句：動詞過去式；

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

3、提出過去的未發生的條件：主句：主語＋would/should/might/could have＋動詞過去分詞

從句：had＋動詞過去分詞

例句： If I had read the book, I would have told you about it.

if的用法

if作為從屬連詞,可引導條件狀語從句、讓步狀語從句和名詞從句。

if引導條件狀語從句,從句可為真實條件從句,也可為虛擬條件從句。如為真實條件從句,謂語用陳述語氣,表示可能性很大,作「假使」「如果」解,通常用一般現在時代替一般將來時; 如果if從句中用will,表示意願。

從句如為虛擬條件從句,謂語動詞要用虛擬語氣,表示可能性不大或與過去事實相反,作「要是,假如」解。可指過去的情況,也可指現在和將來的情況。指將來情況時可用were to或should。在現代口語中,一、三人稱後常用was代替were。if引導的虛擬條件句中,助動詞were,should,had可以移至主語前,此時if可省略。

if引導的條件從句中可以省略be和主語。

if引導的條件從句,有時後接only以加強其語氣,表示說話人非常盼望某人提出的條件能夠實現。

if可引導讓步狀語從句,作「雖然,即使」解,常和even連用。

if可引導名詞性從句,作「是否」解,常放在ask, doubt, know, learn, see, wonder等動詞後。一般用在口語中,而且不能用於句首。

Ⅱ if虛擬語氣的三種時態

1、對現在情況的虛擬

條件從句中謂語動詞用一般過去式，主句用「would/should/might/could+動詞原形」形式，表示對現在不可能實現情況的假想。

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

如果我是你，我會選擇在小城鎮工作。（事實上我不是你）

注意：在條件從句中，如果謂語動詞是be的形式，不管主語是單數還是復數，書面語中用were,而口語中如果是單數，也可以用was,不過在if I were...中一般用were.

2、對過去情況的虛擬

條件從句中謂語動詞用過去完成式，主語用「would/could/should/might+have+動詞的過去分詞」形式。

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

如果昨天沒有你的幫助，我不會趕上公交車。（事實是你昨天已經幫助了我，所以我趕上了車)

3、對將來情況的虛擬

在表示與將來事實相反的條件從句中，謂語動詞可用should do,were to do或動詞的過去式三種形式表示，但意義略有不同。should表示的可能性最大，動詞過去式的可能性次之，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，人人皆可成為聰明人。（事實是並不是所有的事都可以重新做一次)

注意：在書面語中，如果虛擬條件從句中有were，had 或 should，可以把if省略，把這幾個詞放到主語之前，構成主謂倒裝。

(2)虛擬語氣三種時態造句擴展閱讀

其他條件句：

1、錯綜時間條件句

有些條件句的主句謂語和從句謂語表示的動作在時間上並不一致，這類句子稱為錯綜時間條件句。

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

如果當時聽我的勸，你現在就不會有麻煩了。(if 條件句是對過去的虛擬，故用過去完成時，而主句是對現在的虛擬，故用「would+動詞原形」形式）

2、含蓄條件句

有些句子雖不含條件從句，但意思和條件句相差不多，這種句子稱為「含蓄條件句」，這種句子有時候會用虛擬語氣。

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 表後悔的虛擬語氣的時態搭配是什麼樣的講清楚點，我只要結構，每個帶點例句更好

個人覺得這個講的還可以
僅供參考，不代表個人觀點
一、 條件句中的虛擬語氣
1. 條件句中虛擬語氣的形式
從句中提出一種與客觀現實不相符或根本不可能存在的條件，主句會產生的一種不可能獲得的結果。條件句中的虛擬語氣根據不同的時間有三種不同的形式。
時間 從句謂語形式 主句謂語形式

將來 動詞過去式(be用were)
should + 動詞原形
were to + 動詞原形
would / should / might / could + 動詞原形
現在 動詞過去式(be 用 were) would / should / might / could + 動詞原形
過去 had +動詞過去分詞 would / should / might / could have + 動詞過去分詞
2. 條件中的虛擬語氣的舉例
(1) 將來時的條件句中的虛擬語氣。如：
If he should go to Qing Hua University, he would make full use of his time. 如果他要上清華大學的話，他就會充分利用他的時間了。
If he were to come here, he would tell us about it. 如果他要來的話，他會通知我們一聲。
(2) 現在時的條件句中的虛擬語氣。如：
If he were free, he would help us. 要是他有空的話，它會幫助我們的。
If he studied at this school, he would know you well. 如果他在這所學校學習的話，它會對你很熟悉。
(3) 過去時的條件句中的虛擬語氣。如：
If I had seen the film, I would have told you about it. 我如果看過這場電影，我會把電影內容告訴你了。
If I had got there earlier, I would have met Mr. Li. 如果我早點到那兒，我就會會到了李先生。
3. 運用條件句中的虛擬語氣時，須注意的幾個問題
(1) 當從句的主語為第三人稱單數時，謂語動詞若是系動詞be時，可用was代替were。但在倒裝虛擬結構及if I were you, as it were中，只能用were。如：
Were I ten years younger, I would study abroad. 要是我還年輕十歲的話，我會去國外學習。
If I were you, I would try my best to grasp the chance. 要是我是你的話，我要盡力抓住這次機會。
(2) 有時，虛擬條件句中，主、從句的動作若不是同時發生時，須區別對待。
①從句的動作與過去事實相反，而主句的動作與現在或現在正在發生的事實不符。如：
If I had worked hard at school, I would be an engineer, too. 如果我在學校學習刻苦的話，我現在也會使工程師了
If they had informed us, we would not come here now. 如果他們通知過我們的話，我們現在就不會來這里了。
②從句的動作與現在事實相反，而主句的動作與過去事實不符。如：
If he were free today, we would have sent him to Beijing. 如果他今天有空的話，我們會已經派他去北京了。
If he knew her, he would have greeted her. 要是他認識她的話，他肯定會去問候她了。
③從句的動作與過去發生的情況相反，而主句的動作與現在正在發生的情況相反。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話，莊家會長得更好。
If he had been working hard, he would be working in the office now. 要是他工作一直努力的話，他現在已進了辦公室了。
(3) 當虛擬條件句的謂語動詞含有were, should, had時，if可省略，而將were, should, had等詞置於句首。如：
Should he agree to go there, we would send him there. 要是他答應去的話，我們就派他去。
Were she here, she would agree with us. 如果她在這兒的話，她會同意我們的。
Had he learnt about computers, we would have hired him to work here. 如果她懂一些電腦知識的話，我們會已經聘用他來這里工作了。
(4) 有時，句子沒有直接給出假設情況的條件，而須通過上下文或其他方式來判斷。如：
I would have come to see you, but I was too busy. 我本該來看你了，然而我太忙了。
But for his help, we would be working now. 要不是他的幫助，我們還會在工作呢。
Without your instruction, I would not have made such great progress. 要是沒有你的指導，我不會取得如此大的進步。
(5) 有時，虛擬條件句中，主、從句可以省略其中的一個，來表示說話人的一種強烈的感情。
①省略從句
He would have finished it. 他本該完成了。
You could have passed this exam. 你應該會通過這次考試了。
②省略主句
If I were at home now. 要是我現在在家裡該多好啊。

Ⅳ 求英語倒裝句分類及復雜例句！以及三種時態虛擬語氣的分別例句！越復雜越好！

倒裝句

英語最基本的語序是主語在前，謂語動詞在後。但有時由於句子結構的需要或表示強調，就要採用倒裝形式。將謂語動詞完全移到主語之前稱為完全倒裝，只將助動詞或情態動詞放到主語之前稱為部分倒裝。強調性倒裝和以so， neither， nor開頭的句子是高考例題的熱點。
一、倒裝句的意義

1. 適應一定的語法結構的需要，主要是指疑問句句型結構的需要。

e.g. May I come in？

Was the People『s Liberation Army founded in 1927？

2. 為了強調某一部分，而把這部分放到句首，構成倒裝。

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

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

二、倒裝的使用情況

1. 在「there be」結構里，there是引導詞，主語在be後。

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

2. 在疑問句中。

e.g. Is she singing in the classroom？

What does your mother do？
3. 在here， there等副詞開頭的某些句子里（要用一般現在時態）。如果主語是人稱代詞，主語和主要動詞的詞序不變。（完全倒裝）

e.g. There goes the bell.

Here is an apple for you.

There she comes.

4. 重復倒裝句型，用在以so， nor， neither開頭，表示謂語所述的情況也適用於另一個人或一事物的肯定或否定句中。so用於肯定句，表示「也一樣」「也這樣」；nor， neither用於否定句，表示「同樣也不，也不這樣」。

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

My parents didn't watch TV last night. Neither （Nor） did I.
5. 直接引語的全部或一部分放在句首時，主句中的主謂也常直接倒裝。（完全倒裝）

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等否定副詞開頭的句子中，採用部分倒裝。如不放在句首就不要倒裝。

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

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

比較：I shall never forget the day when I joined the Army.
7. 用於以only所修飾的副詞、介詞短語或狀語從句的句子中。

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後的片語不是狀語，不需倒裝。

e.g. Only Wang Lili knows this.
8. 為了表達生動，有時把表地點、方位的副詞，如 up， down， out， away， in等放在句首，同時把謂語動詞放在主語之前。若主語為人稱代詞，主語和謂語動詞的位置不變，只將副詞放在句首。（完全倒裝）

e.g. Away hurried the boy.

Out rushed the girl.

9. 在虛擬結構中，條件從句的謂語含有were， had 和should這三個詞是，可省去if，將這些詞移至主語之前。

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引導讓步狀語從句時要倒裝（形容詞/ 副詞/ 名詞/ 動詞 + as + 主語 + 謂語）。

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

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

Hard as he worded， he made little progress.
11. 用於某些表示祝願的句子里。

e.g. May you succeed！

Long live the People『s Republic of China！

12. So + 形容詞、副詞及such 置於句首時要倒裝。

So happy did he feel.

Such was me.

Ⅵ 求助虛擬語氣各種情況的例句舉例和解析~

第一步：掌握對現在，對過去，對將來的虛擬的固定時態
對現在的虛擬：
If he were free, he would help us. 要是他有空的話，它會幫助我們的。
注意，虛擬中的is,都用were
注意，主句用would +動詞原型，從句用過去式
對過去的虛擬
If I had seen the film, I would have told you about it. 我如果看過這場電影，我會把電影內容告訴你了
注意時態：主句用would +現在完成時，從句用過去完成時
對將來的虛擬
If he were to come here, he would tell us about it.
如果他要來的話，他會通知我們一聲。
或，if he came here...
if he should come here....
主句用would +動詞原型，從句分三種：過去式，were to,should
第二步：掌握錯綜虛擬，即主從句的動作（看時態提示詞），有錯綜

If he were free today, we would have sent him to Beijing.
如果他今天有空的話，我們會已經派他去北京了。
本來主句用了would +現在完成時，說明是對過去的虛擬，從句本來應該用過去完成時，但是，由於從句中有個時態提示詞，today,則套用對現在的虛擬的公式，用過去式
If he had been working hard, he would be working in the office now.
要是他工作一直努力的話，他現在已進了辦公室了。
從句用了過去完成時，說明死對過去的虛擬，本來主句要用would +現在完成時，可是，主句里有個時態提示詞，now,則主句套用現在的虛擬，用would +動詞原型
這樣根據主句，從句不同的時態，針對不同時間的虛擬，叫錯綜虛擬

第三步，含蓄虛擬語氣，就是把if 省略，用倒裝
Were she here, she would agree with us. 如果她在這兒的話，她會同意我們的。
=if she were here,she would agree with us
第四步，虛擬語氣再名詞性從句中的應用
對於表建議，命令，要求的詞，虛擬比較固定，一律用should +動詞原型，但是should 可以省略

advise, ask, demand, desire, decide, insist(堅決要求) , order,
propose, request, suggest(建議) 表示請求、要求、命令或建議等意義的動詞所接的賓語從句一般用虛擬語氣，其虛擬語氣的結構為：(should) + 原形動詞。如：
The teacher advised that we （should） make good use of every minute here.
老師勸我們要好好地利用在這兒的每一分鍾。

Ⅶ 如何辨別虛擬語氣中的三種時態

1、對現在的虛擬結構：if+主語+動詞動詞過去時，主語+should/would+動詞原形 ，should不可以省略。

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

【翻譯】如果我有足夠的錢，我就能去參加游泳俱樂部了。

2 、對過去的虛擬結構：if+主語+had+過去分詞，主語+should/would+have+動詞過去時。

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

【翻譯】如果她能早點告訴他危險，他就不會受傷了。

3 、對將來的虛擬結構：if+主語+should+動詞原形（were to+動詞原形），主語+would/should+動詞原形，這個should可以省略。

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

【翻譯】如果他當初聽我的意見，現在就不會受那麼多的罪了。

Ⅷ 給你一個句子，如何辨別虛擬語氣中的三種時態，請舉例子

一、與現在事實相反
若與現在事實相反，虛擬語氣的條件從句的謂語用過去式(be通常用were)，主句謂語用「should (would, could, might)+動詞原形」。如：
If you took a taxi，you'd get there quicker. 如果你坐計程車去，你可以快一點到那裡。(但你不坐)
If I knew her number I could ring her up. 要是我知道她的電話號碼，我就可以給她打電話了。(可惜我不知道)
二、與過去事實相反
若與過去事實相反，虛擬語氣的條件從句的謂語用過去完成時(had+過去分詞)，主句謂語用「should (would, could, might)+have+過去分詞」。如：
If I'd left sooner，I'd have been on time. 要是我早點動身，我就准時到了。(但我動身太遲了)
If we had found him earlier we could have saved his life. 要是我們當時早點找到他的話，我們就可以救活他。(可惜我們找到他太晚了)
三、與將來事實相反
若與將來事實相反，條件從句的謂語用過去式(be通常用were)，主句謂語用「should (would, could, might)+動詞原形」。如：

Ⅸ 虛擬語氣的的三種情況下主句從句各用什麼時態並寫一個例句

在for
fear
that，in
