學(xué)習(xí)英語(yǔ)的幫手就是興趣，英語(yǔ)有許多的知識(shí)是需要記憶的，也是學(xué)習(xí)英語(yǔ)的基礎(chǔ)。下面小編給大家分享一些高中英語(yǔ)重要知識(shí)點(diǎn)，希望能夠幫助大家!

高中英語(yǔ)重要知識(shí)1

疑問(wèn)代詞概說(shuō)

"疑問(wèn)代詞有who(誰(shuí)，主格)，whom(誰(shuí)，賓格)，whose(誰(shuí)的，所有格)，what(什么)和which(哪個(gè)，哪些)等。

疑問(wèn)代詞用于特殊疑問(wèn)句中

疑問(wèn)代詞一般都放在句首，并在句中作為某一句子成分。如：

Who is going to speak to us tomorrow?明天誰(shuí)來(lái)跟我們講話?(who作主語(yǔ))

Who told you so?是誰(shuí)告訴你的?(who作主語(yǔ))

Whom are you talking about ?你們?cè)谡f(shuō)誰(shuí)?(whom作賓語(yǔ)，但在句首時(shí)口語(yǔ)常用who代替whom)

Whose umbrella is this ?這是誰(shuí)的傘?(whose作定語(yǔ))

What is that? 那是什么?(what作表語(yǔ))

What did he say?他說(shuō)什么?(what作賓語(yǔ))

Which is yours，the blue pen or the redone?藍(lán)筆和紅筆哪一支是你的?(which作主語(yǔ))

[注一]關(guān)于疑問(wèn)代詞的各種用法，可參看77.70-77.72。

[注二]疑問(wèn)代詞who，what，which等后面加單詞ever，可強(qiáng)調(diào)語(yǔ)氣，表達(dá)說(shuō)話人的各種感情。如：

What ever do you want?你到底想要什么?

Who ever is she looking for ?她究竟是在找誰(shuí)?

[注三]which表示在一定范圍之內(nèi)的選擇，what則沒(méi)有這種限制。如：

What do you usually have for lunch?你們午飯通常吃些什么?

Which do you like best?你最喜歡哪一個(gè)?

Which of you comrades come from the Northeast? 你們同志們中間誰(shuí)是東北人?

疑問(wèn)代詞可以引導(dǎo)一個(gè)間接疑問(wèn)句

間接疑問(wèn)句在句中可用作主語(yǔ)、賓語(yǔ)、表語(yǔ)等。疑問(wèn)代詞本身在間接疑問(wèn)句中又擔(dān)任一定的句子成分。如：

Who will be in charge of the work is still not decided.誰(shuí)將負(fù)責(zé)這項(xiàng)工作，現(xiàn)在還沒(méi)有決定。(疑問(wèn)代詞who引導(dǎo)一個(gè)主語(yǔ)從句，它本身又在從句中用作主語(yǔ)。)

Do you know what his name is?你知道他叫什么名字嗎?(疑問(wèn)代詞what引導(dǎo)一個(gè)賓語(yǔ)從句，而它本身又在從句中用作表語(yǔ)。)

[注一] what所引導(dǎo)的名詞性從句(即主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句) 有時(shí)不是間接疑問(wèn)句。如：

What he says is quite true.他所講的話很對(duì)。(what相當(dāng)于that which。它引導(dǎo)一個(gè)主語(yǔ)從句，這個(gè)從句不是間接疑問(wèn)句。)

Children do what the nurse tells them to do.保育員讓孩子干什么他們就做什么。(what引導(dǎo)一個(gè)賓語(yǔ)從句，這個(gè)從句也不是間接疑問(wèn)句。)

[注二] whatever，whoever，whichever等詞可引導(dǎo)名詞性從句。這些名詞性從句也不是間接疑問(wèn)句。whatever，whoever，whichever也可引導(dǎo)表示讓步的狀語(yǔ)從句。見(jiàn)15.65和15.72)如：

They eat whatever they can find.他們找到什么就吃什么。(whatever引導(dǎo)一個(gè)賓語(yǔ)從句，并在從句中作賓語(yǔ)。)

I've got plenty of books 1eft.Whoever wants an extra copy can get one from me.我還剩下許多書(shū)，誰(shuí)還想再要一本可來(lái)拿。(whoever引導(dǎo)一個(gè)主語(yǔ)從句，并在從句中作主語(yǔ)。)

高中英語(yǔ)重要知識(shí)2

關(guān)系代詞

兩種可用來(lái)引導(dǎo)從句并將從句和主句連接起來(lái)的代詞

這樣的代詞一方面在從句中用作句子成分，可作主語(yǔ)、賓語(yǔ)、定語(yǔ)等;另一方面又起連詞的作用。這樣的代詞有關(guān)系代詞和疑問(wèn)代詞兩種。

關(guān)系代詞概說(shuō)

關(guān)系代詞有who，whose，whom，that，which等，用來(lái)引導(dǎo)定語(yǔ)從句。它們?cè)诙ㄕZ(yǔ)從句中可用作主語(yǔ)、賓語(yǔ)、定語(yǔ)或表語(yǔ);另一方面它們又代表主句中為定語(yǔ)從句所修飾的那個(gè)名詞或代詞(這樣的名詞和代詞叫做先行詞)。如：

The man who is talking with Mr. Brown is an eye Specialist和布朗先生談話的那個(gè)人是個(gè)眼科大夫。(關(guān)系代詞who在從句中用作土語(yǔ)，它的先行詞是man)

He is the comrade whom you have been looking for他就是你要找的那位同志。(關(guān)系代詞whom在從句中作賓語(yǔ)，它的先行詞是comrade，whom在口語(yǔ)中一般可省去)

The old man whose son is in the navy used to be carpenter.兒子在海軍的那位老人過(guò)去是個(gè)木匠。

(關(guān)系代詞whose在從句中用作定語(yǔ)，先行詞為man)

The film which I saw last night is about a young teacher.我昨晚看的那部電影說(shuō)的是一個(gè)年輕教師的事。(關(guān)系代詞which在從句中用作賓語(yǔ)，先行詞為film, which在口語(yǔ)中可省略)

This is the plane that will fly to Tokyo in the afternoon.這是下午要飛往東京的飛機(jī)。(關(guān)系代詞that在從句中用作主語(yǔ)，先行詞為plane)

高中英語(yǔ)重要知識(shí)3

不定代詞的用法

不定代詞大都可代替名詞和形容詞，在句中可用作主語(yǔ)、賓語(yǔ)、表語(yǔ)和定語(yǔ)。如：

1.用作主語(yǔ)

Both of them are waiters.他們倆人都是男侍者。

Is everybody here?人都到了嗎?

2.用作賓語(yǔ)

I know little about the novel關(guān)于這本小說(shuō)我知道的很少。

china will become a powerful modern country in another twenty years.再過(guò)二十年中國(guó)將成為現(xiàn)代化強(qiáng)國(guó)。

[注]有些不定代詞也可用作同位語(yǔ)和狀語(yǔ)。如：

Wang and Li both made good progress.王和李兩人都有很大進(jìn)步。

They all went to the Zoo.他們都去動(dòng)物園了。

Are you any good at mathematics?你數(shù)學(xué)好嗎?

高中英語(yǔ)重要知識(shí)5

一. 直接引語(yǔ)和間接引語(yǔ)

(一)直接引述別人的原話，叫做直接引語(yǔ);用自己話轉(zhuǎn)述別人的話，叫做間接引語(yǔ)。間接引語(yǔ)一般構(gòu)成賓語(yǔ)從句。直接引語(yǔ)必須放在引號(hào)內(nèi)，間接引語(yǔ)則不用引號(hào)。直接引語(yǔ)改為間接引語(yǔ)時(shí)，除將引語(yǔ)部分變成賓語(yǔ)從句外，還必須對(duì)直接引語(yǔ)中的人稱、時(shí)態(tài)、指示代詞、時(shí)間狀語(yǔ)、地點(diǎn)狀語(yǔ)等進(jìn)行改變。

1. 時(shí)態(tài)的變化：直接引語(yǔ)變?yōu)殚g接引語(yǔ)時(shí)，通常受轉(zhuǎn)述動(dòng)詞said, asked等的影響而使用過(guò)去化的時(shí)態(tài)，即把原來(lái)的時(shí)態(tài)向過(guò)去推，也就是一般現(xiàn)在時(shí)變?yōu)橐话氵^(guò)去時(shí)，現(xiàn)在進(jìn)行時(shí)變?yōu)檫^(guò)去進(jìn)行時(shí)，等等。例如：

Tom said to me,“My brother is doing his homework.”

→Tom said to me that his brother was doing his homework.

2. 人稱代詞、指示代詞、時(shí)間狀語(yǔ)、地點(diǎn)狀語(yǔ)等等的變化：根據(jù)意義進(jìn)行相應(yīng)的變化，例如：

She asked Jack,“Where have you been?”

→She asked Jack where he had been.

He said,“These books are mine.”

→He said that those books were his.

(二)直接引語(yǔ)改為間接引語(yǔ)時(shí)，都使用陳述語(yǔ)序，但是因?yàn)樵涞木涫讲煌?，所以變成間接引語(yǔ)時(shí)所用的連詞會(huì)有所不同。直接引語(yǔ)如果是一般疑問(wèn)句，用連接詞whether或if;如果是特殊疑問(wèn)句，則用疑問(wèn)詞引導(dǎo)間接引語(yǔ)。轉(zhuǎn)述的動(dòng)詞一般用asked，可以在其后加上一個(gè)間接賓語(yǔ)me, him, her, us等。如：

She said,“Is your father at home?”

→She asked me if/whether my father was at home.

“What do you do every Sunday?”My friend asked me.

→My friend asked me what I did every Sunday.

直接引語(yǔ)如果是祈使句，改為間接引語(yǔ)時(shí)，要將祈使句的動(dòng)詞原形變?yōu)閹o的不定式，并在不定式的前面根據(jù)原句的語(yǔ)氣(即請(qǐng)求或命令)加上ask, tell, order等動(dòng)詞，如果祈使句為否定式，則在不定式前加not。其句型為：ask / tell / order someone (not) to do something. 例如：

She said to us,“Please sit down.”

→She asked us to sit down.

He said to him,“Go away!”

→He ordered him to go away.

He said, “Don’t make so much noise, boys.”

→He told the boys not to make so much noise.

二. 各種時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)

被動(dòng)語(yǔ)態(tài)概述

被動(dòng)語(yǔ)態(tài)的概念：它是動(dòng)詞的一種形式，表示主語(yǔ)與謂語(yǔ)之間的執(zhí)行或被執(zhí)行關(guān)系。主動(dòng)語(yǔ)態(tài)表示主語(yǔ)是謂語(yǔ)動(dòng)作的執(zhí)行者，例如：They saw the little boy crying by the river. 被動(dòng)語(yǔ)態(tài)表示主語(yǔ)是謂語(yǔ)動(dòng)作的承受者，例如：The little boy was seen crying by the river.

被動(dòng)語(yǔ)態(tài)的構(gòu)成

被動(dòng)語(yǔ)態(tài)的形式是由“助動(dòng)詞be+動(dòng)詞的過(guò)去分詞”構(gòu)成。助動(dòng)詞be隨著主語(yǔ)的人稱、數(shù)、時(shí)態(tài)等的不同而變化。幾種常見(jiàn)時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)形式如下：

1. 一般現(xiàn)在時(shí) am/is/are + 過(guò)去分詞

例如：Rice is planted in the south of China.

2. 一般過(guò)去時(shí) was/were + 過(guò)去分詞

例如：These trees were planted the year before last.

3. 一般將來(lái)時(shí) will/shall + be + 過(guò)去分詞

例如：A sports meeting will be held next week in our school.

4. 現(xiàn)在進(jìn)行時(shí) am/is/are + being + 過(guò)去分詞

例如：Your radio is being repaired now.

5. 過(guò)去進(jìn)行時(shí) was/were + being + 過(guò)去分詞

When he got there, the problem was being discussed.

6. 現(xiàn)在完成時(shí) have/has + been + 過(guò)去分詞

His work has been finished.

Has his work been finished? Yes, it has. / No, it hasn’t.

7. 過(guò)去完成時(shí) had + been + 過(guò)去分詞

注意：

1.除了be之外的其它系動(dòng)詞如get, stay等也可以和過(guò)去分詞構(gòu)成被動(dòng)語(yǔ)態(tài)。例如：Their questions haven’t got answered.

2. 含有情態(tài)動(dòng)詞的謂語(yǔ)變成被動(dòng)語(yǔ)態(tài)使用“情態(tài)動(dòng)詞+ be + 過(guò)去分詞”結(jié)構(gòu)。例如：

More attention should be paid to the old in this country.

This work can’t be done until Mr. Black comes.

3. 含有“be going to”, “be to”等結(jié)構(gòu)的謂語(yǔ)，其被動(dòng)語(yǔ)態(tài)分別用“be going to + be + 過(guò)去分詞”和“be to + be + 過(guò)去分詞”。例如：

The problem is going to be discussed at the next meeting.

All these books are to be taken to the library.

4. 被動(dòng)語(yǔ)態(tài)與系表結(jié)構(gòu)的區(qū)別：“連系動(dòng)詞+用作表語(yǔ)的過(guò)去分詞”構(gòu)成的系表結(jié)構(gòu)，與被動(dòng)語(yǔ)態(tài)的形式完全一樣，所以應(yīng)注意它們的區(qū)別。被動(dòng)語(yǔ)態(tài)中的過(guò)去分詞是動(dòng)詞，多強(qiáng)調(diào)動(dòng)作;系表結(jié)構(gòu)中的過(guò)去分詞相當(dāng)于形容詞，多強(qiáng)調(diào)狀態(tài)。前者通?？捎胋y 引出動(dòng)作的執(zhí)行者，而后者則不可以。例如：

The map was changed by someone.(被動(dòng)結(jié)構(gòu))

That custom remained unchanged for many centuries.(系表結(jié)構(gòu))

系表結(jié)構(gòu)中的過(guò)去分詞通常可被very修飾，被動(dòng)語(yǔ)態(tài)中的過(guò)去分詞往往要用much修飾。

例如：

He was very excited.(系表結(jié)構(gòu))

He was much excited by her words.(被動(dòng)結(jié)構(gòu))

5. 主動(dòng)形式表被動(dòng)意義。有些動(dòng)詞的主動(dòng)形式有被動(dòng)意味，如 open, read, sell, shut, wash, wear, write等。此時(shí)句子的主語(yǔ)一般是物。例如：

These books sell well. 這些書(shū)很暢銷。

The door won’t shut. 這門(mén)關(guān)不上。

The clothes wash well. 這些衣服很好洗。
