高二的時(shí)候，英語(yǔ)語(yǔ)法的學(xué)習(xí)可以為高三做好英語(yǔ)學(xué)習(xí)基礎(chǔ)的充足準(zhǔn)備。下面是學(xué)習(xí)啦小編給大家整理的高二英語(yǔ)語(yǔ)法的相關(guān)知識(shí)，供大家參閱!
高二英語(yǔ)語(yǔ)法：表語(yǔ)從句
1. 定義：用作表語(yǔ)的從句叫做表語(yǔ)從句。
2. 構(gòu)成：關(guān)聯(lián)詞+簡(jiǎn)單句
3. 引導(dǎo)表語(yǔ)從句的關(guān)聯(lián)詞的種類：
(1) 從屬連詞that。如：
The trouble is that I have lost his address. 麻煩是我把他的地址丟了。
(2) 從屬連詞whether, as, as if。如：
He looked just as he had looked ten years before. 他看起來(lái)還與十年前一樣。
The question is whether they will be able to help us. 問(wèn)題是他們是否能幫我們。
注：從屬連詞if一般不用來(lái)引導(dǎo)表語(yǔ)從句，但as if卻可引導(dǎo)表語(yǔ)從句，如： All this was over twenty years ago, but it's as if it was only yesterday. 這都是20多年前的事了，但宛如昨天一樣。
能跟表語(yǔ)從句的謂語(yǔ)動(dòng)詞一般為系動(dòng)詞be, seem, look等。如：
It looked as if it was going to rain. 看起來(lái)天要下雨了。
(3)連接代詞who, whom, whose, what, which, whoever, whatever, whichever 連接副詞 where, when, how, why。
如：The problem is who we can get to replace her. 問(wèn)題是我們能找到誰(shuí)去替換她呢。
The question is how he did it. 問(wèn)題是他是如何做此事的。
That was what she did this morning on reaching the attic. 那就是她今晨上了閣樓干的。
解釋：
1. 連詞because可引導(dǎo)表語(yǔ)從句。如：
I think it is because you are doing too much. 我想這是因?yàn)槟阕龅锰唷?/p>
2. 在一些表示“建議、勸說(shuō)、命令”的名詞后面的表語(yǔ)從句中，謂語(yǔ)動(dòng)詞用虛擬語(yǔ)氣。should+動(dòng)詞原形表示，should可省略。如：
My suggestion is that we (should) start early tomorrow. 我的建議是我們明天一早就出發(fā)。
高二英語(yǔ)語(yǔ)法：賓語(yǔ)從句
1. 定義：用作賓語(yǔ)的從句叫賓語(yǔ)從句。
2. 構(gòu)成：關(guān)聯(lián)詞+簡(jiǎn)單句
3. 引導(dǎo)賓語(yǔ)從句的關(guān)聯(lián)詞有三類：
(1) 從屬連詞that。如：
He told us that he felt ill. 他對(duì)我們說(shuō)他感到不舒服。
I know he has returned. 我知道他已經(jīng)回來(lái)了。
注： that在引導(dǎo)賓語(yǔ)從句時(shí)也并不是任何情況下都可以省略。在以下情況下，that不能省略。
1. Everybody could see what happened and that Tom was frightened.(and連接兩個(gè)賓語(yǔ)從句，that賓語(yǔ)從句放在and的后面時(shí)，that不能省略。) 大家都會(huì)看出所發(fā)生的事情并知道Tom非常害怕。
2.I know nothing about him except that he is from the south.(that引導(dǎo)的賓語(yǔ)從句作介詞賓語(yǔ)時(shí)，that不能省略。)
對(duì)他我一無(wú)所知，只知道他是南方人。
3.That he ever said such a thing I simply don’t believe. (that從句位于句首時(shí)，that不可省略。)
我簡(jiǎn)直不相信他曾說(shuō)過(guò)這樣的話。
4. We decided, in view of his special circumstances, that we would admit him for a probationary period. (主句謂語(yǔ)動(dòng)詞與that從句之間有插入語(yǔ)，that不可省略。)
鑒于他的特殊情況，我們決定應(yīng)允他一段試用期。
(2)從屬連詞if/whether。如：
I doubt whether he will succeed. 我懷疑他是否會(huì)成功。
I don’t know if you can help me. 我不知道你能否幫助我。
(3)連接代詞who, whom, whose, what, which, whoever, whatever, whichever 連接副詞 where, when, how, why。
如：
Who or what he was, Martin never learned.
他是什么人?他是干什么的?馬丁根本不知道。
I wonder what he’s writing to me about. 我不知道他要給我寫(xiě)信說(shuō)什么事。 I’ll tell you why I asked you to come. 我會(huì)告訴你我為什么要你來(lái)。 You may do what you will. 你可做任何你想做的事。
(1) 介詞賓語(yǔ)從句
賓語(yǔ)從句也可用作介詞的賓語(yǔ)。如：
He was deeply displeased by what had occurred that day.
他對(duì)那天發(fā)生的事感到很不快。
I walked over to where she sat. 我走向她坐的地方。
I am curious as to what he will say. 我很想知道他要說(shuō)什么。
Your success will largely depend upon what you do and how you do it. 你是否成功將主要取決于你做什么和怎樣做。
有時(shí)介詞可以省略。如：
I don’t care (for) who marries him. 我不管誰(shuí)跟他結(jié)婚。
Be careful (as to) how you do that. 你要注意做這件事的方式。 解釋：
1.如果賓語(yǔ)從句后還有賓語(yǔ)補(bǔ)足語(yǔ)，則用it作形式賓語(yǔ)，而將賓語(yǔ)從句后置。如：
We thought it strange that Xiao Wang did not come yesterday. 我們認(rèn)為小王昨天沒(méi)來(lái)是奇怪的。
He has made it clear that he will not give in.
他已表明他不會(huì)屈服。
2.作介詞的賓語(yǔ)：連詞that引導(dǎo)的名詞性從句很少作介詞的賓語(yǔ)，只用在except, but, in后。其他一些介詞的賓語(yǔ)從句如果由連詞that引導(dǎo)，則需用it先行一步，作形式賓語(yǔ)。如：
He is a good student except that he is careless.
他是一個(gè)好學(xué)生，只是有點(diǎn)粗心。
You may rely on it that I shall help you. 你可以指望我會(huì)幫助你的。 介詞賓語(yǔ)不可以用which來(lái)引導(dǎo)，而要用what來(lái)引導(dǎo)。如：
Are you sorry for what you've done?
你為你所做的一切感到內(nèi)疚嗎?
3.某些形容詞或過(guò)去分詞后常接賓語(yǔ)從句，這類形容詞或過(guò)去分詞有sure, glad, certain, pleased, happy, afraid, surprised, satisfied等，連詞that可省略。如：
I am not sure what I ought to do.
我不能確定我該做什么。
I'm afraid you don't understand what I said.
恐怕你沒(méi)領(lǐng)會(huì)我說(shuō)的意思。
I'm surprised that I didn't see all that before.
我好奇怪，我以前沒(méi)看到過(guò)。
Mother was very pleased her daughter had passed the exams.
媽媽為她的女兒通過(guò)了考試而感到高興。
4.連詞whether („or not)或if引導(dǎo)的賓語(yǔ)從句
if和whether引導(dǎo)的賓語(yǔ)從句可以互換使用，但whether常和or not連用，if一般不與or not連用。如：
I wonder whether it is true or not. 我不知它是真是假。
用if引導(dǎo)賓語(yǔ)從句如果會(huì)引起歧義，應(yīng)避免使用if而用wheter。試比較： Please let me know if you want to go.
Please let me know whether you want to go.
if從句可理解為賓語(yǔ)從句，意為“請(qǐng)告訴我你是否想去”;此句又可理解為條件狀語(yǔ)從句意為“如果你想去的話，請(qǐng)告訴我一聲”。
5.賓語(yǔ)從句的否定轉(zhuǎn)移。在think, believe, suppose, expect等動(dòng)詞后的賓語(yǔ)從句，有時(shí)謂語(yǔ)盡管是否定意思，卻不用否定形式，而將think等動(dòng)詞變?yōu)榉穸ㄐ问健Ｈ纾?/p>
I don’t think you are right. 我認(rèn)為你錯(cuò)了。
I don’t believe they have finished their work yet. 我相信他們還未完成他們的工作。
I don’t suppose he cares, does he? 我想他不在意，是嗎?
6. 賓語(yǔ)從句的時(shí)態(tài)變化規(guī)律：
(1) 當(dāng)主句是一般現(xiàn)在時(shí)態(tài)時(shí)，從句可根據(jù)需要用任何時(shí)態(tài)。
(2) 當(dāng)主句是一般過(guò)去時(shí)態(tài)時(shí)，從句只能使用過(guò)去范圍內(nèi)的任何時(shí)態(tài)。但客觀真理除外。如：
The teacher said that the earth goes round the sun.
老師說(shuō)地球繞著太陽(yáng)運(yùn)行。
高二英語(yǔ)語(yǔ)法：主語(yǔ)從句
1. 定義：用作主語(yǔ)的從句叫做主語(yǔ)從句。
2. 構(gòu)成：關(guān)聯(lián)詞+簡(jiǎn)單句
3. 引導(dǎo)主語(yǔ)從句的關(guān)聯(lián)詞有三類：
(1) 從屬連詞that。 如：That they were in truth sisters was clear from the facial resemblance between them.
很明顯，她們確是親姐妹，她們的臉型很相似。
(2) 從屬連詞whether。如：
Whether he’ll come here isn’t clear. 他是否會(huì)來(lái)這里還不清楚。
(3) 連接代詞who, whom, whose, what, which, whoever, whatever, whichever 連接副詞 where, when, how, why。如：
What she did is not yet known. 她干了什么尚不清楚。
How this happened is not clear to anyone. 這事怎樣發(fā)生的，誰(shuí)也不清楚。 Whoever comes is welcome. 不論誰(shuí)來(lái)都?xì)g迎。
Wherever you are is my home ---- my only home. 你所在的任何地方就是我的家----我唯一的家。
解釋：
1. 主語(yǔ)從句能用it作形式上的主語(yǔ)。常以it作形式主語(yǔ)的句型有：
A. It+be+形容詞(obvious, true, natural, surprising, good, wonderful, funny, possible, likely, certain, probable, etc.)+that從句。如： It is certain that she will do well in her exam. 毫無(wú)疑問(wèn)她考試成績(jī)會(huì)很好。
It is probable that he told her everything. 很可能他把一切都告訴她了。
B. It+be+名詞詞組(no wonder, an honour, a good thing, a pity, no surprise, etc.)+that從句。如：

It’s no surprise that our team should have won the game. 我們沒(méi)贏這場(chǎng)比賽真意外。
C. It+be+過(guò)去分詞(said, reported, thought, expected, decided, announced, arranged, etc.)+that從句。如：

It seems that Alice is not coming to the party at all. Alice似乎不來(lái)參加晚會(huì)。
It happened that I was out that day. 碰巧我那天外出了。
E. It+doesn’t matter (makes no difference, etc.)+連接代詞或連接副詞引起的主語(yǔ)從句。如：

F. 當(dāng)that引導(dǎo)的主語(yǔ)從句出現(xiàn)在疑問(wèn)句中時(shí)，要以it作形式主語(yǔ)，而把主語(yǔ)從句后置。如：
Is it true that the scientist will give us a lecture next week? 下周那位科學(xué)家將給我們作報(bào)告是真的嗎?
Does it matter much that they will not come tomorrow? 他們明天不來(lái)很要緊嗎?
G. 當(dāng)主語(yǔ)從句出現(xiàn)在感嘆句中時(shí)，要以it作形式主語(yǔ)，而把主語(yǔ)從句后置。如： How strange it is that the children are so quiet! 孩子們這么安靜真奇怪!
2.注意連接代詞whoever, whatever, whichever等引導(dǎo)主語(yǔ)從句的含義
Whoever comes will be welcome. (whoever=the person who) 來(lái)的人將受到歡迎。
Whatever he did was right. (whatever=the thing that) 他所做的事情是正確的。
