高考英語虛擬語氣語法手記
以下是小編搜集分享給大家的高考英語虛擬語氣語法手記，一起來看看吧。
一。考綱要求
根據(jù)考綱的要求，虛擬語氣部分主要考查情態(tài)動詞的選擇、虛擬語氣在條件句中、在名詞性從句中、在簡單句中或在日常交際中的使用等基本用法。
二。命題導向
依據(jù)語境來判斷虛擬語氣的不同形式是高考試題的主要設題方法之一。在近年的高考試題中，出現(xiàn)了對陳述語氣與虛擬語氣辨析的考查。虛擬語氣在各種從句中的應用是該部分的重點掌握內(nèi)容。
三。復習要點
虛擬語氣是一種特殊的動詞形式，說話人陳述的并不是事實，而是表達一種愿望、假設和猜測等。只有在非真實的條件句中才使用虛擬語氣，如果假設的條件有可能實現(xiàn)，用真實條件句。如果假設的條件無法實現(xiàn)或?qū)崿F(xiàn)的可能性很小，則用虛擬語氣。使用虛擬語氣的情況主要有下列幾種：
1. 虛擬語氣在非真實條件句中的運用
(1) if條件狀語從句中的虛擬語氣
非真實條件句表示不可能實現(xiàn)的或?qū)崿F(xiàn)的可能性很小假設。條件句與主句皆須用虛擬語氣。其虛擬語氣的時態(tài)形式有三種：
�、俦硎九c現(xiàn)在事實相反的假設，從句的謂語動詞用“動詞過去式(be一般用were)”，主句的謂語動詞用“should (would, could, might)+動詞原形”。例如：
If you were the UN Secretary General, could you stop the wars on the earth?
If he had a chance, he would/should/ might/could choose to study abroad。
�、诒硎九c過去事實相反的假設，從句的謂語動詞用“had+過去分詞”，主句的謂語動詞用“should (would, could, might)+have+過去分詞”。
If Li Ming had spent more time on her studies, she might/would/could/should have been admitted to Tsinghua University last year。
⑵ 省略連詞if 的虛擬條件句中
如果把連接條件從句的連詞if省略，必須將從句的謂語部分的助動詞had, 情態(tài)動詞should或系動詞were等移至主語之前，構(gòu)成倒裝語序。例如：
Had he known my address(=If he had known my address)， he would have visited me earlier。
Should I meet Jay Zhou some day(=If I should meet Jay Zhou some day)， I might tell him that I like him.
Were I you(=If you were I)， I would get on well with my teachers and classmates。
【記憶小竅門】可提到句首的詞有三個：had, should和were。諧音記憶：一馬當先“還屬我”。
�、呛钐摂M條件句
有時，可不用條件句表示一個非真實的條件，而用一些介詞短語或通過上下文中暗含某種非真實的條件，這種句子叫做“含蓄條件句”。例如：
�、偻ㄟ^with, without, but for和動詞不定式短語等表示虛擬的條件
She’d look better with shorter hair. =if she had her hair cut shorter
Without your help, we could not have completed the task ahead of time. =If it had not been for your help…
But for the heavy snow, I could have gone on holiday. =If there had not been the heavy snow…
She would be shocked to hear the news. =If she heard the news…
It would be easier to do it in this way. =If you did it in this way…
②句中含有or, or else, otherwise, but等詞語，暗示句子的某一部分(前句或后句)需用虛擬語氣。
He was on business in Beijing at that time; otherwise he might have helped us。
Luckily Mary telephoned to inform me of the meeting, or would have been I absent。
I should have attended my friend’s wedding ceremony, but I couldn’t afford the time。
2.虛擬語氣在名詞性從句中的運用
�、旁谥髡Z從句中， 在下面的幾種情況下，謂語動詞通常用“should +動詞原形”
�、買t is+形容詞+that…句型。常見的形容詞有important, necessary, natural, funny, strange, surprising, astonishing(令人驚訝的)等。
② It is +名詞+that…句型。常見的名詞有pity, shame, advice, suggestion, proposal(提議，建議)， requirement, request, desire, order等。
�、� It is+動詞的過去分詞+ that…句型。常見的動詞有advise, order, propose, request, suggest, demand, require等。
在以上三種句型中，主語從句的謂語動詞要用“should+動詞原形”， should可省略。例如：
It is important that we (should) have a good knowledge of computer in modern times。
It is necessary that these useful expressions (should) be learnt by heart。

The captain insisted that the wounded soldier (should) be sent to hospital at once。

【記憶小竅門】一個“堅持”和”催促”、二個“命令”， 三個“要求”， 四個“建議”。
�、窃诤衋dvice, order, demand, proposal(提議) requirement, suggestion等名詞的表語從句、同位語從句中，謂語動詞用“should+動詞原形”，should可省略。

My suggestion is that the project (should) be completed by the end of the year。
在一些名詞性從句中，謂語動詞用“should+動詞原形”或“should +have done”，表示驚訝、意志等感情色彩，譯為“竟然，居然”。
I am surprised /shocked that you should speak in such a way。
I find it astonishing that he should be so rude to his mum。
It is strange /surprising that she should not have been invited。

�、仍趙ish后的賓語從句中

3. 在as if/though 后的方式狀語從句中，表示某種情況與現(xiàn)在的事實相反， 謂語動詞用過去式;表示即將發(fā)生的情況“用情態(tài)動詞+動詞原形”;表示某種的情況有過去的事實相反， 謂語動詞用過去完成時。

May the friendship between us last long!
四. 注意事項
1. 錯綜時間虛擬條件句中
如果if條件句表示的動作與主句表示的動作發(fā)生的時間不一致，從句和主句的謂語動詞的形式要根據(jù)各自的時間來調(diào)整， 這種情況被稱作“錯綜時間虛擬語氣”或“混合虛擬語氣”。
If America had not made wars on Iraq, the Iraqi people would be living a peaceful life now。
If I were you, I would have visited the museum yesterday.
If we didn’t have an exam tomorrow, my friends and I could be playing football now。

—We have to carry it on, since we’ve got everything ready。

—How was you interview?
—It couldn’t have been better. Luckily, I found all the answers to questions。
—Shall I give you a ride as you live so far away?
4. 若insist表示“堅持說”，suggest表示“暗示，表明”，其后的賓語從句用陳述語氣。
The smile on the boy’s face suggested that he was happy to die for his country。
The man insisted that he had not stolen anything and (should) be set free immediately。
5. 如果as if/though從句描述的是真實的情況，謂語動詞則用陳述語氣，而不用虛擬語氣。
It looks as if it is going to rain。
It sounds as though she has been really ill。
6. 在“had better/would rather, would like/love to, was/were to+ have done sth ”表示過去希望做某事，但事實上未做。例如：
— Do you mind if I open the window?
—I’d rather you didn’t. I feel a bit cold。
