⑴ 英語中虛擬語氣的用法
在表示假想的虛假的、與事實相反的或難以實現的情況時用虛擬語氣， 表示主觀願望或某種版強烈情感時，也用權虛擬語氣。即當一個人說話時欲強調其所說的話是基於自己的主觀想法，願望，假想，猜測，懷疑或建議，而不是根據客觀實際，就用虛擬語氣。主要是英語語法的一種表達，與真實語氣相對。
⑵ 英語語法中的虛擬語氣,教教我該怎麼掌握
虛擬語氣
1） 概念
[Subjunctive Mood]
中文譯作"虛擬語氣"。它是一種動詞形式，表示說話人的某種假設、願望、懷疑、猜測、建議等含義。
2） 在條件句中的應用
條件句可分為兩類，一類為真實條件句，一類為非真實條件句。非真實條件句表示的是假設的或實際可能性不大的情況，故採用虛擬語氣。
●虛擬語氣的使用范圍及判斷
一、虛擬語氣表示一種不能實現的假設。該語法主要用於if條件狀語從句。也可用於主語從句、表語從句、賓語從句等。
二、if條件狀語從句中虛擬語氣的判斷
判斷是真實條件句還是非真實條件句。只有在非真實條件句中才使用虛擬語氣。通過句子意思，看假設的條件是否能夠實現，能夠實現是真實條件句，不能使用虛擬語氣；假設的條件不能實現則是非真實條件句，要用虛擬語氣。
判斷這個假設是與哪個事實相反。通常有三種情況：①與過去事實相反。②與現在事實相反。③與將來事實可能相反。
三、「後退一步法」
後退一步法是指在准確地判斷了該句與哪一事實相反後，按虛擬語氣的後退一步法處理從句謂語動詞的時態。即：在非真實條件狀語從句中，謂語動詞按正常情況「後退一步」。也就是：
①與過去事實相反，在從句中用過去完成時形式表示。
②與現在事實相反，在從句中用過去一般時形式表示。
③與將來事實可能相反，在從句中用過去將來時形式表示。
主句中則用情態動詞would, should, could 等加一個與從句一致的動詞形式。
例：If I had come her yesterday, I would have seen him.
If I were a teacher, I would be strict with my students.
If it should snow tomorrow, they couldn』t go out.
四、注意事項
①if條件句中如有were, should, had，可以省去if，並使用倒裝語序。
②在現代英語中if條件狀與從句中的謂語動詞如果是be其過去形式一般用were。
●賓語從句中的虛擬語氣
一、wish 後面賓語從句中的虛擬語氣
wish 後面賓語從句中的虛擬語氣，按「後退一步法」處理從句的謂語動詞。注意：與哪個事實相反，不能以主句的時態為判斷依據，而是根據從句的意義判斷。
二、表示「要求、建議、命令」等動詞後面的賓語從句中的虛擬語氣
從句中用「should + 動詞原形」構成。而且should可以省去。用於此結構的動詞有：advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest等。
注意：當insist表示「堅持認為」、suggest表示「表明，顯示」時，不用虛擬語氣。
The look on his face suggested that he was quite satisfied with what I had done for him.
He insisted that he was honest.
三、would rather ＋從句
在這種結構中，從句的位於動詞用過去形式表示虛擬。
I would rather you did this instead of me.
●主語從句中的虛擬語氣
一、It be + 形容詞 + that ．．．（should）．．．
用於該句型的形容詞是：necessary, good, inportant, right, wrong, better, natural, proper, funny, strange, surprising ．
一些名詞也可以用於 在該結構中。如：a pity， no wonder．．．．
二、It be + 過去分詞 + that ．．．（should）．．．．
用於該結構中的過去分詞是表示「建議、請求、命令」等詞的過去分詞。如：desired， suggested， requested， ordered， proposed等。
三、It is time（about time， high time）that ．．．（過去式動詞形式或should＋動詞原形）．．．．
It is high time I went home now. = It is high time I should go home now.
●表語從句、同位語從句中的虛擬語氣
在suggestion， proposal， order， plan， idea， advice， decision等需要有內涵的名詞後面的表語從句、同位語從句中，要使用虛擬語氣。其謂語動詞應用：should＋原形動詞。另外連接從句的that不能省略。
例：My suggestion is that weshould go there at once.
What do you think of his proposal that we should put on a play at the English evening?
⑶ 請教英語語法-虛擬語氣的使用方法.
虛擬語氣中有一種叫著虛擬條件句（或叫著含蓄條件句），而非真實條件句中的條件從句有時不表達出來，只暗含在副詞、介詞短語、上下文或其他方式表示出來，這種句子叫做含蓄條件句，在多數情況下，條件會暗含在短語中，如without…，but for…，in the absence of···，otherwise等。這些句子中的結構一般如下：
主句：主語+should/would/could/might+do/have done。
從句，but that/otherwise + 主語 + 過去時態
eg：
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。
We didn't know his telephone number,otherwise we would have telephoned him. 我們不知道他的電話號碼，否則我們就會給他打電話。
in the absence of sunlight, there would be no moonlight. 如果沒有太陽光，就不會月光。
but表示讓步關系，意思是「除非，要不是」，常與that一起構成but that, 相當於"if...not"。 例如：I would have failed but that your helped me.要不是你們幫助我，我就會失敗。

⑹ 英語語法中的虛擬語氣，怎麼用呢
Subjunctive Mood (虛擬語氣)
從句 主句
現在時間 陳述語氣 does shall/will do
虛擬語氣 did should/would do
過去時間 陳述語氣 did should/ would do
虛擬語氣 had done should/would have done
將來時間 陳述語氣 does, am/is/are to do shall/will do
虛擬語氣 should do, were to do should/would do
Wish虛擬句
現在式→過去式， 過去式→過去完成式
＊ 如果wish是過去式，虛擬從句無時態變化。
＊ wish cf· hope wish引導的從句表示願望實現的可能性很小
hope 引導的從句表示願望有可能實現
動詞 advise, agree, appoint, arrange, argue, ask, command, decide, decree, demand, desire, determine, direct, expect, insist, intend, order, permit, persist, propose, prefer, pray, provide, recommend, request, require, suggest, urge等之後加(should) do.
動詞變成過去式，從句無時態變化。
上述動詞轉化成名詞後，引導的從句也加(should) do
eg. I suggest that a meeting (should) be held as soon as possible.
My suggestion is that a meeting (should) be held as soon as possible.
I suggested that a meeting (should) be held as soon as possible.
It is + 下述形容詞+ that+ （should） do
advisable, appropriate, better, desirable, essential. Good, imperative, important, necessary, proper, right, urgent, vital
eg. It is essential that everyone (should) bear this in mind.
It is + 下述形容詞+ that+ should do
absurd, amazing, annoying, awkward, funny, natural, odd, pitiful, a pity, regrettable, to be regretted, ridiculous, strange, surprising.
＊ should 不能省略
if only + 虛擬式
would rather/sooner + that + 虛擬式
＊ would rather/sooner + (to) do
eg. I would rather you came tomorrow.
I would rather wait.
It is (high) time + that + did
lest, for fear that, in case + should do
But for…, 虛擬句
But that…, 虛擬句
With/ without…, 虛擬句
公式化的虛擬句
God bless you.
Long live China.
Suffice to say that we won.
May you live a long and happy life!
Come what may, we will go ahead with our plan.
Heaven forbid that I should let my own parents suffer.
條件句中的were, had, should 等助動詞移到句首，省略if, 構成倒裝虛擬條件句。
Eg. If he had come earlier, he would not miss the bus.
Had he come earlier, he would not miss the bus.
⑺ 英語語法關於虛擬語氣簡單一問
在suggestion, proposal, idea, plan, order, advice……這些命令、建議、要求等名詞後面的表語從句、同位語從句中，要用虛擬語氣，即（should）+動詞原形。例如：
1. My idea is that we (should) get more people to attend the conference.
2. I make a proposal that we (should) hold a meeting next week.
在表示命令、建議、要求，如order, suggest, propose, require, demand, request, insist, command, insist 等一類動詞後面的從句中+ (should) do
1.I suggest that we (should) hold a meeting next week.
2.He insisted that he (should ) be sent there.
注意： 如suggest, insist等詞，表示其本意"暗示、表明"、"堅持認為"時，賓語從句用陳述語氣，不用虛擬語氣。表示"建議" 或"堅持要某人做某事時"，即用虛擬語氣，should+動詞原形
所以說，我們是根據詞意判斷是否用虛擬，而非詞性是動詞或名詞。
⑻ 英語語法中的虛擬語氣，教教我該怎麼掌握
一、虛擬語氣的使用范圍：
虛擬語氣用來表示說話人所說的話並不是事實，而是一種假設、願望、懷疑或推測。該語法主要用於if 條件狀語從句中，也可用於主語從句、表語從句和賓語從句等。
二、虛擬語氣的判斷：
1. if 條件狀語從句中虛擬語氣的判斷。if 條件狀語從句有真實條件句和非真實條件句。假設條件可以實現的句子為真實條件句，反之為非真實條件句，要用虛擬語氣。其形式分為以下三種：
(1) 與過去事實相反的假設。結構為：從句的謂語動詞用「had + 過去分詞」，主句用「should (would, could, might) + have + 過去分詞」。例如：
If it had not rained so hard yesterday, we could have played tennis. 如果昨天沒有下大雨，我們就能玩網球了。
(2) 與現在事實相反的假設。結構為：從句的謂語動詞用過去式，系動詞用were，主句的謂語用「should (would, could, might) + 動詞原形」。例如：
If I were in your position, I would marry her. 如果我是你，我就娶她為妻。
(3) 與將來事實相反的假設。結構為：從句的謂語動詞用「should (were to) + 動詞原形」，主句用「should
(would, could, might) + 動詞原形」。 例如：
If you should miss the chance, you would feel sorry for it. 如果你錯過了這次機會，你會難過的。
2. 賓語從句中的虛擬語氣。
(1) wish後接賓語從句中的虛擬語氣：根據從句的意義來判斷。
A: 表示與現在和將來事實相反的願望，從句謂語動詞用過去時態。例如：
I wish they were not so late. 要是他們來得不是這么晚就好了。
B: 表示與過去事實相反的願望，從句謂語動詞用過去完成時態。例如：
I wished he hadn't done that. 我真希望那件事不是他做的。
(2) 表示「要求、建議、命令」等動詞後面的賓語從句中的虛擬語氣。用於此結構的動詞有：advise, direct, agree, ask, demand, decide, desire, insist, order, prefer, propose, request, suggest等。從句的謂語動詞用「should + 動詞原形」，其中should 可以省去。例如：
I insisted that he (should) go with us. 我堅持讓他和我們一起去。
注意：當insist 表示「堅持認為」、suggest表示「表明，顯示」時，不用虛擬語氣。例如：
He insisted that she was honest. 他堅持認為她是誠實的。
3. 主語從句中的虛擬語氣。
(1) It be + 形容詞 + that... (should)...。用於該句型的形容詞有：necessary, good, important, right, wrong, better, natural, proper, funny, strange, surprising等。例如：
It's natural that he should feel hurt. 他感到疼是很正常的。
(2) It be + 過去分詞 ＋ that... (should)...。用於該結構中的過去分詞是表示「建議、請求、命令」等詞的過去分詞。如： desired, suggested, requested, ordered, proposed等。例如：
It is desired that the building of the house be completed next month. 真希望這所房子在下個月前就能竣工。
(3) It is time (about time / high time) that... + (過去時或should + 動詞原形)...。例如：
It is high time I went home now. = It is high time I should go home. 我該回家了。
(4) 表語從句、同位語從句中的虛擬語氣。在suggestion, proposal, order, plan, idea, advice, decision等需要具體內容解釋的名詞後要使用虛擬語氣，其謂語動詞為：should + 動詞原形，連接從句的that不能省略。例如：
My suggestion is that we should go there at once. 我的建議是我們應該馬上去那兒。
4． 省略形式。有時可以把含有助動詞、情態動詞、be或have的虛擬條件句中的連詞if 省去，而將had, should, were 等詞提到主語之前，即用倒裝結構。這時，如果出現not等否定詞時需放在主語後面。例如：
If she had been here five minutes earlier she would have seen her old friend. → Had she been here five minutes earlier she would have seen her old friend. 如果她早到五分鍾，她就會看見她的老朋友了。
⑼ 老師讓我們自己准備英語語法中虛擬語氣的用法在課上來講，求大家幫忙
虛擬語氣表示說話人的願望、假設、猜測或建議,而不表示客觀存在的事實。虛擬語氣通過謂語動詞的特殊形式來表示。下面分別介紹虛擬語氣在各種句式中的用法。
1. 虛擬語氣用於條件狀語從句
注意:主句中的should通常用於第一人稱,would可用於任何人稱,同時也可根據意思用情態動詞could, might等代替should, would。
1)表示與現在事實相反:
If I were you, I should stay at home.
If the peasants could farm the land themselves, food proction would be much higher.
If fewer cash crops were grown, more food could be proced and there would be less or no starvation.
2)表示與過去事實相反:
If you had come yesterday, you would have met him.
If the hurricane had happened ring the daytime, there would have been many deaths.
3)表示與將來事實相反:If you came tomorrow, we would have the meeting.
If it were to/should rain tomorrow, the meeting would be put off.
If it should rain, the crops would be saved.
4)當條件狀語從句表示的行為和主句表示的行為所發生的時間不一致時,動詞的形式要根據它所表示的時間來調整。例如:If you had followed the doctor's advice, you would be quite all right now. (從句說的是過去,主句指的是現在.)
5)以上句型可以轉換成下列形式:①從句省略if,用倒裝句式"were, had, should+主語"。例如:Were I in school again, I would work harder. Had you been here earlier, you would have seen him. Should there be a meeting tomorrow, I would come.②用介詞短語代替條件狀語從句。例如:Without air, there would be no living things. I would not have succeeded but for your help.
2.虛擬語氣用於賓語從句
1)"wish+賓語從句"表示不能實現的願望,漢語可譯為"可惜……"、"……就好了"、"悔不該……"、"但願……"等。表示現在不能實現的願望,從句的謂語動詞用過去式;表示將來不能實現的願望,用"would(could)+動詞原形";表示過去不能實現的願望,用"had+過去分詞"或"(could)would + have + 過去分詞"。例如:
I wish we could go to the seaside today.
I wish you told me earlier.
We wish we had arrived there two hours earlier.
2)虛擬語氣在動詞arrange, command, demand, desire, insist, order, propose, request, require, suggest 等後面的賓語從句中,用"(should)+動詞原形"。例如:
I suggested that the meeting (should) be put off.
The doctor ordered that she (should) stay in bed for a few days.
They demanded that the black people should be treated as well as white people.
注意:insist作"力言"、"強調"解時,賓語從句不用虛擬語氣。只有當insist作"堅持(應該)"解時,賓語從句才用虛擬語氣。例如:
Mike insisted that he had never stolen anything.
I insisted that you give me my money back.
3.虛擬語氣用於表語從句、同位語從句做advice, idea, order, demand, plan, proposal, suggestion, request 等名詞的表語從句和同位語從句,其謂語動詞要用虛擬語氣的結構"(should)+動詞原形"。例如:
We all agreed to his suggestion that we (should)go to Beijing for sightseeing.
My idea is that he (should) do exercises first.
4.虛擬語氣用於以as if(as though)引導的表語從句或狀語從句
如果從句表示與現在事實相反,謂語動詞用一般過去時;表示與過去事實相反,謂語動詞用"had+過去分詞";表示與將來事實相反,謂語動詞用"would(might, could )+動詞原形"。例如:
He looked at me as if I were mad.
He speaks English so fluently as if he had studied English in England.
It looks as if it might rain.
但as if(as though)後的從句也常用陳述語氣,這是因為從句中的情況往往是可能發生的或可能被設想為真實的。例如:
It looks as if our side is going to win.
5.虛擬語氣用於主語從句
在主語從句中,謂語動詞的虛擬語氣結構用"should+動詞原形"的結構,表示驚奇、不相信、惋惜、理應如此等。例如:
It is necessary (important, natural, desirable, advisable, strange, etc.) that we should clean the room every day.
It was a pity (a shame, no wonder, etc.) that you should be so careless.
It will be desired (suggested, decided, ordered, requested, proposed, etc.) that she should finish her homework this afternoon.
在上述三種主語從句中,should意為"應該"、"竟然",可以省去,但不可換用would。主句所用動詞的時態不限。
注意:這種從句表示的是事實。如果說話人對這種事實表示驚奇,就可用虛擬語氣。反之,如果不表示驚奇,that從句也可用陳述語氣。例如:
It is strange that he did not come yesterday.
It is a pity that you can't swim.
⑽ 英語語法里什麼是虛擬語氣具體講一下
虛擬語氣(subjunctive mood)(有時稱為連接語氣(conjunctive mood))是很多語言都有的動詞語氣。它典型的用在從屬專子句中表達希屬望、命令、情緒、可能性、判斷、必然性、或與當前事實相反的陳述。虛擬語氣的詳情隨語言而不同。
