動詞的語態(tài)是動詞的一種形式,表示主語和謂語之間語法或語義的關系，許多同學都掌握得不好。讓我們一起學習吧!以下小編為大家編輯的動詞的語態(tài)英語基礎語法知識點匯總，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想，所說的是一個條件，紛歧定是事實，或與事實相反。
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。非真實條件句示意的是假設的或現(xiàn)實可能性不大的情形，故接納虛擬語氣。
真實條件句
真實條件句用于陳述語氣，假設的情形可能發(fā)生，其中 if 是若是的意思。
時態(tài)關系
句型： 條件從句 主句
一樣平?，F(xiàn)在時 shall/will + 動詞真相
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。真實條件句主句為未來時，從句用一樣平?，F(xiàn)在時。
注重：
在真實條件句中，主句不能用be going to示意未來，該用shall, will.
(錯) If you leave now, you are never going to regret it.
(對) If you leave now, you will never regret it.
示意真理時，主句謂語動詞便不用shall (will) +動詞真相，而直接用一樣平?，F(xiàn)在時的動詞形式。
非真實條件句
時態(tài)：可以示意已往，現(xiàn)在和未來的情形。它的基本特點是時態(tài)退后。
a. 同現(xiàn)在事實相反的假設。
句型 ： 條件從句 主句
一樣平常已往時 should( would) +動詞真相
If they were here, they would help you.
b. 示意于已往事實相反的假設。
句型： 條件從句 主句
已往完成時 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. 示意對未來的設想
句型： 條件從句 主句
一樣平常已往時 should+ 動詞真相
were+ 不定式 would + 動詞真相
should+ 動詞真相
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
主句與從句的動作發(fā)生在差其余時間，這時主，從句謂語動詞的虛擬語氣形式因時間差異而差異，這叫做夾雜條件句。
If you had asked him yesterday, you would know what to do now.
(從句與已往事實相反，主句與現(xiàn)在事實相反。)
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，動詞'be'的已往時態(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詞要用should 加動詞真相， 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語法匯總，希望大家??
,高三地理培訓學校對于基礎知識框架了解不清楚，學習底子特別薄弱的同學來講，或許在校期間老師的進度他已經(jīng)是跟不上的狀態(tài)了。那么這個時候為了快速提升自己也為了不拖自己所在班級的進度，這類同學可以找一個能夠針對自己的學習進度進行系統(tǒng)學習的課外補習班，全面系統(tǒng)的提升自己的能力和成績，這樣的話還是非常有用的。,(suggested
It is (important that…+ (should) do
( a pity
(suggested, ordered, proposed, required, demanded, requested, insisted; + (should) do
(important, necessary, natural, strange
a pity, a shame, no wonder
(It is suggested that we (should) hold a meeting next week.
It is necessary that he (should) come to our meeting tomorrow.
在賓語從句中的應用
在示意下令建議要求等一類動詞后面的從句中。
order, suggest, propose, require, demand, request, insist, command, insist + (should) do
I suggest that we (should) hold a meeting next week.
He insisted that he (should ) be sent there.
注重： 如suggest, insist不示意"建議" 或"堅持要某人做某事時"，即它們用于其本意"示意解釋""堅持以為"時，賓語從句用陳述語氣。
The guard at gate insisted that everybody obey the rules.
判斷改錯:
(錯) You pale face suggests that you (should) be ill.
(對) Your pale face suggests that you are ill.
(錯) I insisted that you ( should) be wrong.
(對) I insisted that you were wrong.
在表語從句，同位語從句中的應用
在suggestion, proposal, idea, plan, order, advice等名詞后面的表語從句同位語從句中要用虛擬語氣，即(should)+動詞真相。
My idea is that we (should) get more people to attend the conference.
I make a proposal that we (should) hold a meeting next week.
wish的用法
用于wish后面的從句，示意與事實相反的情形，或示意未來不太可能實現(xiàn)的愿望。其賓語從句的動詞形式為：
真實狀態(tài) wish后
從句動作先于主句動詞動作 現(xiàn)在時 已往時
(be的已往式為 were)
從句動作與主句動作同時發(fā)生 已往時 已往完成時
(had + 已往分詞)
未來不大可能實現(xiàn)的愿望 未來時 would/could +
動詞真相
I wish I were as tall as you. 我希望和你一樣高。
He wished he hadn't said that. 他希望他沒講那樣的話。
I wish it would rain tomorrow. 我希望明天下雨就好了。
Wish to do表達法。
Wish sb / sth to do
I wish to see the manager. = I want to see the manager.
I wish the manager to be informed at once. (= I want the manager to be informed at once.)
對照if only與only if
only if示意"只有";if only則示意"若是……就好了"。If only也可用于陳述語氣。
I wake up only if the alarm clock rings. 只有鬧鐘響了，我才會醒。
If only the alarm clock had rung. 那時鬧鐘響了，就好了。
If only he comes early. 希望他早點回來。
It is (high) time that
It is (high) time that 后面的從句謂語動詞要用已往式或用should加動詞真相，但should不能省略。
It is time that the children went to bed.
It is high time that the children should go to bed.
need "不必做"和"本不應做"
didn't need to do示意： 已往不必做某事, 事實上也沒做。.
needn't have done示意： 已往不必做某事, 但事實上做了。
John went to the station with the car to meet Mary, so she didn't need to walk back home. 約翰開車去車站接瑪麗，以是她不必步行回家了。
John went to the station with the car to meet Mary, so she needn't have walked back home. 約翰開車去車站接瑪麗，以是她本不必步行回家了。 (Mary步行回家，沒有遇上John的車。)
典型例題
There was plenty of time. She ___.
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，而時現(xiàn)實上不需要。
Mustn't have done 用法不準確，對已往發(fā)生的事情舉行否認性推斷應為couldn't have done, "不能能已經(jīng)"。 must not do 不能以(用于一樣平常現(xiàn)在時)。
