高二英語補(bǔ)習(xí)機(jī)構(gòu)_虛擬語氣英語語法知識(shí)點(diǎn)匯總
--> I was made to go out of the classroom (by the teacher).
動(dòng)詞的語態(tài)是動(dòng)詞的一種形式,表示主語和謂語之間語法或語義的關(guān)系,許多同學(xué)都掌握得不好。讓我們一起學(xué)習(xí)吧!以下小編為大家編輯的動(dòng)詞的語態(tài)英語基礎(chǔ)語法知識(shí)點(diǎn)匯總,歡迎大家閱??
看法
虛擬語氣用來示意語言人的主觀愿望或設(shè)想,所說的是一個(gè)條件,紛歧定是事實(shí),或與事實(shí)相反。
在條件句中的應(yīng)用
條件句可分為兩類,一類為真實(shí)條件句,一類為非真實(shí)條件句。非真實(shí)條件句示意的是假設(shè)的或現(xiàn)實(shí)可能性不大的情形,故接納虛擬語氣。
真實(shí)條件句
真實(shí)條件句用于陳述語氣,假設(shè)的情形可能發(fā)生,其中 if 是若是的意思。
時(shí)態(tài)關(guān)系
句型: 條件從句 主句
一樣平常現(xiàn)在時(shí) shall/will + 動(dòng)詞真相
If he comes, he will bring his violin.
典型例題
The volleyball match will be put off if it ___.
A. will rain B. rains C. rained D. is rained
謎底B。真實(shí)條件句主句為未來時(shí),從句用一樣平?,F(xiàn)在時(shí)。
注重:
在真實(shí)條件句中,主句不能用be going to示意未來,該用shall, will.
(錯(cuò)) If you leave now, you are never going to regret it.
(對(duì)) If you leave now, you will never regret it.
示意真理時(shí),主句謂語動(dòng)詞便不用shall (will) +動(dòng)詞真相,而直接用一樣平?,F(xiàn)在時(shí)的動(dòng)詞形式。
非真實(shí)條件句
時(shí)態(tài):可以示意已往,現(xiàn)在和未來的情形。它的基本特點(diǎn)是時(shí)態(tài)退后。
a. 同現(xiàn)在事實(shí)相反的假設(shè)。
句型 : 條件從句 主句
一樣平常已往時(shí) should( would) +動(dòng)詞真相
If they were here, they would help you.
b. 示意于已往事實(shí)相反的假設(shè)。
句型: 條件從句 主句
已往完成時(shí) should(would) have+ 已往分詞
If she had worked harder, she would have succeeded.
The rice would not have been burnt if you had been more careful.
If my lawyer had been here last Saturday, he would have prevented me from going.
If he had come yesterday, I should / would have told him about it.
寄義:He did not come yesterday, so I did not tell him about it.
If he had not been ill and missed many classes, he would have made greater progress.
寄義: He was ill and missed many lessons, so he did not make greater progress.
c. 示意對(duì)未來的設(shè)想
句型: 條件從句 主句
一樣平常已往時(shí) should+ 動(dòng)詞真相
were+ 不定式 would + 動(dòng)詞真相
should+ 動(dòng)詞真相
If you succeeded, everything would be all right.
If you should succeed, everything would be all right.
If you were to succeed, everything would be all right.
夾雜條件句
主句與從句的動(dòng)作發(fā)生在差其余時(shí)間,這時(shí)主,從句謂語動(dòng)詞的虛擬語氣形式因時(shí)間差異而差異,這叫做夾雜條件句。
If you had asked him yesterday, you would know what to do now.
(從句與已往事實(shí)相反,主句與現(xiàn)在事實(shí)相反。)
If it had rained last night (已往), it would be very cold today (現(xiàn)在).
虛擬條件句的倒裝
虛擬條件句的從句部門若是含有were, should, 或had, 可將if省略,再把were, should或had 移到從句句首,執(zhí)行倒裝。
Were they here now, they could help us.
=If they were here now, they could help us.
Had you come earlier, you would have met him
=If you had come earlier, you would have met him.
Should it rain, the crops would be saved.
=Were it to rain, the crops would be saved.
注重:
在虛擬語氣的從句中,動(dòng)詞'be'的已往時(shí)態(tài)一律用"were",不用was, 即在從句中be用were取代。
If I were you, I would go to look for him.
若是我是你,就會(huì)去找他。
If he were here, everything would be all right.
若是他在這兒,一切都市好的。
典型例題
_____ to do the work, I should do it some other day.
A. If were I B. I were C. Were I D. Was I
謎底C. 在虛擬條件狀語中若是有were, should, had這三個(gè)詞,通常將if省略,主語提前, 釀成 were, should, had +主語的形式。但要注重,在虛擬條件狀語從句中,省略連詞的倒裝形式的句首不能用動(dòng)詞的縮略形式。如我們可說 Were I not to do., 而不能說 Weren't I to do.
特殊的虛擬語氣詞:should
It is demanded / necessary / a pity + that…結(jié)構(gòu)中的主語從句的謂語動(dòng)詞要用should 加動(dòng)詞真相, should 可省略。
句型:
) 疑問句(Interrogative Sentences):提出問題。有以下四種:
句子的類型句子可以從不同的角度進(jìn)行分類。按照句子的語氣,句子可分為陳述句祈使句感嘆句疑問句四種,一般稱為句類。以下是小編整理的句子的種類英語基礎(chǔ)語法匯總,希望大家??
,高三地理培訓(xùn)學(xué)校對(duì)于基礎(chǔ)知識(shí)框架了解不清楚,學(xué)習(xí)底子特別薄弱的同學(xué)來講,或許在校期間老師的進(jìn)度他已經(jīng)是跟不上的狀態(tài)了。那么這個(gè)時(shí)候?yàn)榱丝焖偬嵘约阂矠榱瞬煌献约核诎嗉?jí)的進(jìn)度,這類同學(xué)可以找一個(gè)能夠針對(duì)自己的學(xué)習(xí)進(jìn)度進(jìn)行系統(tǒng)學(xué)習(xí)的課外補(bǔ)習(xí)班,全面系統(tǒng)的提升自己的能力和成績(jī),這樣的話還是非常有用的。,(suggested

order, suggest, propose, require, demand, request, insist, command, insist + (should) do

注重: 如suggest, insist不示意"建議" 或"堅(jiān)持要某人做某事時(shí)",即它們用于其本意"示意解釋""堅(jiān)持以為"時(shí),賓語從句用陳述語氣。
The guard at gate insisted that everybody obey the rules.
判斷改錯(cuò):
(錯(cuò)) You pale face suggests that you (should) be ill.
(對(duì)) Your pale face suggests that you are ill.

wish的用法
用于wish后面的從句,示意與事實(shí)相反的情形,或示意未來不太可能實(shí)現(xiàn)的愿望。其賓語從句的動(dòng)詞形式為:
真實(shí)狀態(tài) wish后
從句動(dòng)作先于主句動(dòng)詞動(dòng)作 現(xiàn)在時(shí) 已往時(shí)
(be的已往式為 were)
從句動(dòng)作與主句動(dòng)作同時(shí)發(fā)生 已往時(shí) 已往完成時(shí)
(had + 已往分詞)
未來不大可能實(shí)現(xiàn)的愿望 未來時(shí) would/could +
動(dòng)詞真相

Wish to do表達(dá)法。

對(duì)照if only與only if

A. mustn't have hurried B. couldn't have hurried C. must not hurry D. needn't have hurried
謎底D。needn't have done. 意為"本不必",即已經(jīng)做了某事,而時(shí)現(xiàn)實(shí)上不需要。
Mustn't have done 用法不準(zhǔn)確,對(duì)已往發(fā)生的事情舉行否認(rèn)性推斷應(yīng)為couldn't have done, "不能能已經(jīng)"。 must not do 不能以(用于一樣平?,F(xiàn)在時(shí))。
