英語(yǔ)語(yǔ)法知識(shí)點(diǎn)(大全15篇)
在平凡的學(xué)習(xí)生活中，說(shuō)起知識(shí)點(diǎn)，應(yīng)該沒(méi)有人不熟悉吧？知識(shí)點(diǎn)就是“讓別人看完能理解”或者“通過(guò)練習(xí)我能掌握”的內(nèi)容。還在為沒(méi)有系統(tǒng)的知識(shí)點(diǎn)而發(fā)愁嗎？下面是小編整理的英語(yǔ)語(yǔ)法知識(shí)點(diǎn)，希望對(duì)大家有所幫助。
英語(yǔ)語(yǔ)法知識(shí)點(diǎn)1
現(xiàn)在分詞表示主動(dòng)關(guān)系，同時(shí)表示動(dòng)作正在進(jìn)行：
There is someone waiting for him.
有人在等他。
There was a man standing in front of me.
我前面站著一個(gè)男人。
There were some children swimming in the river.
有些小孩在河里游泳。
There were a group of young people working in the fields.
有一群青年在地里勞動(dòng)。
有時(shí)現(xiàn)在分詞可表示一種狀態(tài)：
There’s a piano standing against the wall.
靠墻有一架鋼琴。
There’re a lot of difficulties facing us.
我們面前有很多困難。
There is a door leading to the garden.
有一座門通往花園。
有個(gè)別現(xiàn)在分詞用于該結(jié)構(gòu)時(shí)可以表示將來(lái)(正如它們可用進(jìn)行時(shí)表示將來(lái)一樣)：
There are ten people coming to dinner.
有10個(gè)人來(lái)吃晚飯。
英語(yǔ)語(yǔ)法強(qiáng)調(diào)句知識(shí)點(diǎn)：判斷此題是定語(yǔ)從句還是強(qiáng)調(diào)句
有這樣一道題：
It was in the small house _________ was built with stones by his father _________ he spent his childhood.
A. which, that B. that, which C. which, which D. that, where
答案選A，填對(duì)此句的關(guān)鍵是要弄清第二空必須填 that，因?yàn)檫@是一個(gè)強(qiáng)調(diào)句，被強(qiáng)調(diào)部分為 in the small house (以及修飾它的定語(yǔ)從句 which was built with stones by his father)。又如：
(1) It was the boy _________ had been in prison _________ stole the money.
A. who, where B. that, how C. who, that D. that, which
【分析】此題答案選C，全句為強(qiáng)調(diào)句，被強(qiáng)調(diào)成分是 the boy (以及修飾它的定語(yǔ)從句who had been in prison)。
(2) It was just in the room _________ he was born _________ he died.
A. where, which B. that, that C. where, that D. which, that
【分析】此題答案選C，全句為強(qiáng)調(diào)句，被強(qiáng)調(diào)成分是 in this room，where he was born 為修飾 the room 的定語(yǔ)從句。
英語(yǔ)語(yǔ)法強(qiáng)調(diào)句知識(shí)點(diǎn)：強(qiáng)調(diào)句與從句的比較
1. 強(qiáng)調(diào)句與主語(yǔ)從句的比較
強(qiáng)調(diào)句將句子中的it is / was …that同時(shí)省去，句子仍然成立;而主語(yǔ)從句將that與后面部分代替it，成立。如：
(1) It is Li Lei’s brother that you met in the street yesterday. 你昨天在街上所見(jiàn)到的就是李蕾的兄弟。
本句若將It is 及 that同時(shí)省去為：You met Li Lei’s brother in the street yesterday. 句子同樣成立，因此前面的句子是強(qiáng)調(diào)句型。
(2) It is exciting that we have succeeded in sending up Shenzhou V. 我們成功地發(fā)射了神舟五號(hào)這件事情真令人興奮。
本句若將It is 及 that同時(shí)省去為：We have succeeded exciting in sending up Shenzhou V. 顯然句子錯(cuò)誤，因此，前面句子不是強(qiáng)調(diào)句型，而是主語(yǔ)從句。
2. 強(qiáng)調(diào)句與定語(yǔ)從句的比較
◎強(qiáng)調(diào)句中的`It沒(méi)有實(shí)際意義，It be與that可同時(shí)被省略;而定語(yǔ)從句中的It是主語(yǔ)，It be與that不可同時(shí)省略;
◎強(qiáng)調(diào)句型中be的時(shí)態(tài)須跟后面句子的時(shí)態(tài)相一致;而定語(yǔ)從句中主句謂語(yǔ)動(dòng)詞be的時(shí)態(tài)須由主句的時(shí)間確定
◎強(qiáng)調(diào)句將句子中的that不能省略，并且即使前面的名詞是事物時(shí)，也不能將that換成which;而定語(yǔ)從句中的that作賓語(yǔ)時(shí)可被省略，并且當(dāng)先行詞是事物時(shí)可用which代替。
◎當(dāng)it be后面的時(shí)間、地點(diǎn)名詞作主語(yǔ)、賓語(yǔ)或表語(yǔ)時(shí)，引導(dǎo)詞可用that / which;而作其他成分時(shí)，引導(dǎo)詞須用when / which。如：
(1) It is an English book (that / which) I bought yesterday. 它是我昨天買的書。(本句是對(duì)What is that?問(wèn)句的回答，that所引導(dǎo)的是定語(yǔ)從句，that可被省略)
It was the English book that I bought yesterday. 昨天我所賣的就是這本書。(本句相當(dāng)于對(duì)I bought the English book yesterday中an English book進(jìn)行強(qiáng)調(diào))
(2) It was a room where we used to have meetings. 它是我們過(guò)去常在開(kāi)會(huì)的房子。(where 所引導(dǎo)的從句對(duì)前面的room進(jìn)行說(shuō)明，它是定語(yǔ)從句)
It was in the room that we used to have meetings. 過(guò)去我們開(kāi)會(huì)就在這間房子里。(in the room是被強(qiáng)調(diào)的部分，本句是強(qiáng)調(diào)句型)
(3) It is a day when the people celebrate their victory. 這是人們慶祝他們的勝利的日子。 (when所引導(dǎo)的從句對(duì)a day進(jìn)行說(shuō)明，是定語(yǔ)從句)
It was on that day that people celebrated their victory. 就在那一天，人們慶祝了他們的勝利。(強(qiáng)調(diào)on October 1, 1949)
3.強(qiáng)調(diào)句與狀語(yǔ)從句的比較
◎狀語(yǔ)從句句首的It本身就是句子的主語(yǔ);而強(qiáng)調(diào)句首的It不作任何成分也沒(méi)有實(shí)際意義。
◎狀語(yǔ)從句的連接副詞that及句子前面的It be不能去掉。
◎狀語(yǔ)從句的引導(dǎo)詞可以是when / where，而強(qiáng)調(diào)句型中的that不能用其他詞代替。如：
(1) It is such an interesting book that we all like it very much. 它是一本如此有趣的書，我們大家都非常喜歡。(結(jié)果狀語(yǔ)主從復(fù)合句)
It is such an interesting book that we all like very much. 我們大家都非常喜歡的就是一本如此有趣的書。(強(qiáng)調(diào)such an interesting book)
(比較：It is such an interesting book as we all like very much. 這就是我們大家都非常喜歡的如此有趣的書。定語(yǔ)從句)
(2) It was already morning when he woke up. 當(dāng)他醒來(lái)時(shí)，已經(jīng)是早晨了。(時(shí)間主從復(fù)合句)
It was the next morning that he woke up. 就在第二天早晨他醒來(lái)了。(強(qiáng)調(diào)the next morning)
英語(yǔ)語(yǔ)法倒裝句知識(shí)點(diǎn)：“only+狀語(yǔ)”置于句首句子要倒裝
請(qǐng)看下面一道涉及only的倒裝試題：
Only in this way __________ able to finish the work in time.
A. can you be B. are you C. you can be D. you are
此題應(yīng)選 B。容易誤選D。至于A，C，這比較容易排除，因?yàn)榍閼B(tài)動(dòng)詞 can 不能與 be able to用在同一謂語(yǔ)中。本題之所以要選B而不選D，主要是因?yàn)榫涫子昧薿nly in thisway 的緣故，按照英語(yǔ)語(yǔ)法規(guī)則：“only+狀語(yǔ)”位于句首，句子通常要用倒裝語(yǔ)序(部分倒裝——用一般疑問(wèn)句形式)。如：
1. “only 副詞”位于句首。如：
Only then did I realize that I was wrong. 只是到了那時(shí)我才意識(shí)到是我錯(cuò)了。
2. “only+介詞短語(yǔ)”位于句首。如：
Only by working hard can you succeed. 只有努力工作你才能成功。
Only in the reading-room can you find him. 你只有在閱覽室才能找到他。
3. “only+狀語(yǔ)從句”位于句首。如：
Only when one loses freedom does one know itsvalue. 一個(gè)人只有在失去自由后才知道自由的可貴。
注意：若位于句首的不是only+狀語(yǔ)，而是 only+賓語(yǔ)等，則通常無(wú)需倒裝(但有時(shí)也可以倒裝)。如：
Only a policeman the children saw in the street. 孩子們?cè)诮稚现豢吹揭粋�(gè)警察。
Only one more point will I make. 我只再說(shuō)明一點(diǎn)。
英語(yǔ)語(yǔ)法感嘆句知識(shí)點(diǎn)：感嘆句的基本句型
【句型一】What + (a / an) + 形容詞 + 名詞 + 主語(yǔ) + 謂語(yǔ)!
What a clever boy he is! (他是個(gè))多么聰明的男孩啊!
What an interesting story it is! (這是個(gè))多么有趣的故事啊!
What fine weather it is! 多好的天氣啊!
What beautiful flowers they are! (它們是)多么漂亮的花啊!
【說(shuō)明】 在感嘆句中，What a / an 常用來(lái)修飾單數(shù)可數(shù)名詞，若其前面的形容詞為元音開(kāi)頭，則用 an。what 是用來(lái)修飾復(fù)數(shù)可數(shù)名詞和不可數(shù)名詞。但有些不可數(shù)名詞，如 rain, surprise, breakfast, lunch 等，當(dāng)前面有形容詞修飾，使抽象名詞具體化時(shí)，則要用 what a / an，如：
What a heavy rain it is! 多大的一場(chǎng)雨啊!
What a great surprise it is! 這多么令人驚奇啊!
What a rich breakfast it is! 多么豐盛的一頓早餐啊!
【句型二】How + 形容詞 / 副詞 + 主語(yǔ) + 謂語(yǔ)!
How well you look! 你氣色真好!

How beautifully you sing! 你唱得真好聽(tīng)!
Strawberries! How nice! 草莓! 多好呀!
How clever the boy is! 這個(gè)男孩多么聰明啊!
How fast he runs! 他跑得多么快啊!
【說(shuō)明】how還可以修飾動(dòng)詞構(gòu)成感嘆句，但動(dòng)詞不提前。如：
How I want to be a doctor! 我多么想成為一名醫(yī)生啊!
How she dances! 她跳得多好啊!
英語(yǔ)語(yǔ)法感嘆句知識(shí)點(diǎn)：陳述句改為感嘆句
感嘆句通常有what, how引導(dǎo)，表示贊美、驚嘆、喜 悅、等感情。what修飾名詞，how 修飾形容詞，副詞或動(dòng)詞，感嘆句結(jié)構(gòu)主要有以下幾種：
How +形容詞+ a +名詞+其他成分!
How+形容詞或副詞+其他成分!
What +名詞+其他成分!
What +a+形容詞+名詞+其他成分!
What + 形容詞+復(fù)數(shù)名詞+其他成分!
What + 形容詞+不可數(shù)名詞+其他成分!
請(qǐng)看以下例子：
It’s an interesting film. 這是一部有趣的電影。
→ What an interesting film it is! 這是一部多有趣的電影啊!
It’s wonderful weather. 天氣很好。
→ What wonderful weather! 天氣真好!
He did the work carefully. 他做這工作很仔細(xì)。
→ How carefully he did the work! 他做這工作多仔細(xì)啊!
Time passed quickly. 時(shí)間過(guò)得很快。
→ How quickly time passed! 時(shí)間過(guò)得真快!

英語(yǔ)語(yǔ)法知識(shí)點(diǎn)3
1.He hardly had anything to eat, ________ he?A. didn’t B. hadn’t C. had D. did
答案：D (選擇A的同學(xué)要注意hardly表示否定;選擇B和C的同學(xué)要注意，反意疑問(wèn)句要用助動(dòng)詞.)
2.He says that he won’t be free until tomorrow.他說(shuō)他到明天才會(huì)有空。
解析: 在這個(gè)復(fù)合句中, that引導(dǎo)的從句做says的賓語(yǔ),被稱為賓語(yǔ)從句。until用在否定句中,構(gòu)成“not...until...” 結(jié)構(gòu),意為“直到……才……”,謂語(yǔ)動(dòng)詞用非延續(xù)性動(dòng)詞;until用在肯定句中,意為“直到……”,主句的謂語(yǔ)動(dòng)詞要用延續(xù)性動(dòng)詞。例如:They didn’t leave until they finished their work. 他們完成了工作才回家。

A. wrong something B. something wrong C. anything wrong D. nothing wrong
要點(diǎn)點(diǎn)撥:形容詞修飾something, nothing, anything, everything等不定代詞時(shí)要后置,故排除A。答案:B

真題:The whole company _____ for a three weeks’ summer holiday. A. shut down B. shut off C. shut up D. shut away要點(diǎn)點(diǎn)撥:shut down意為“關(guān)閉;停工;歇業(yè)”;shut off意為“關(guān)掉(煤氣)”等;shut up意為“關(guān)閉;住嘴”等;shut away意為“隔離;隔絕”。答案:A
5. Our sports meeting has been ____ till next Monday because of the bad weather.
A. put on B. put up C. put off D. put down要點(diǎn)點(diǎn)撥: put on意為“穿上,上演”;put up意為“舉起,掛起,張貼”;put off意為“推遲,延期”; put down意為“放下,寫下,記下”。 答案:C
6. So it goes on, hour after hour. 就這樣繼續(xù)下去,一小時(shí)接一小時(shí)。解析: hour after hour意思為“一小時(shí)接一小時(shí)”。英語(yǔ)中,用after連接兩個(gè)相同的單數(shù)名詞(名詞前不用冠詞)表示“一個(gè)接一個(gè)”
7. 解析: during(in, for) the last(past) + 一段時(shí)間,表示“到現(xiàn)在為止多長(zhǎng)時(shí)間以來(lái)(內(nèi))”,常與現(xiàn)在完成時(shí)態(tài)連用。例如:In the last twenty years China has changed a lot. 在最近二十年內(nèi)中國(guó)發(fā)生了巨大的變化。

英語(yǔ)語(yǔ)法知識(shí)點(diǎn)7
一、不定式做主語(yǔ)：
1、不定式做主語(yǔ)一般表示具體的某次動(dòng)作。===動(dòng)名詞ding 表示習(xí)慣的，經(jīng)常的動(dòng)作。
e.g: T finish the building in a nth is difficult.
T d such things is flish.
T see is t believe. (對(duì)等)
注: 1). 不定式作主語(yǔ)時(shí),謂語(yǔ)用單數(shù)
2). 當(dāng)主語(yǔ)較長(zhǎng)，謂語(yǔ)較短時(shí)，常用it做形式主語(yǔ)，而將不定式放到謂語(yǔ)的.后面。
it做形式主語(yǔ)，不定式放在謂語(yǔ)動(dòng)詞之后常用于下列結(jié)構(gòu)中：
(1)It is/was +ad.+f sb. t d…
(2) It is +ad.+fr sb.+t d…
It is eas / difficult / hard / flish / unwise / right / wrng / unnecessar
(3) it is +a +名詞+ t d...
It is a pit / a pleasure / a pleasant thing / ne’s dut / an hnr / a shae / a crie / n eas b… t d
It taes (sb.) se tie / curage / patience …t d…
It requires curage / patience / hard wr… t d…
*注意: prbable 和 pssible 均可作表語(yǔ)，但pssible可以用不定式作真實(shí)主語(yǔ)， 而prbable不能用不定式作真實(shí)主語(yǔ)。
It is prbable fr hi t ce t the eeting.(錯(cuò)）
It is pssible fr hi t ce t the eeting.
It is pssible / prbable that he will ce t the eeting.
二、不定式做表語(yǔ)
主語(yǔ)是以ai dut hpe idea intentin plan b suggestin wish purpse tas 等為中心詞的名詞詞組 或以 what 引導(dǎo)的名詞性從句表示，后面的不定式說(shuō)明其內(nèi)容, 不定式作表語(yǔ)常表示將來(lái)或現(xiàn)在的動(dòng)作或狀態(tài)。
eg :M idea is t clib the untain fr the nrth.
ur istae was nt t write that letter.
What I wuld suggest is t start wr at nce.
三 、動(dòng)詞不定式作賓語(yǔ)
以不定式結(jié)構(gòu)為賓語(yǔ)的動(dòng)詞有：
as, agree, care, chse, deand, decide, expect, fail, help, hpe, learn, anage, ffer, plan, prepare, pretend, prise, refuse, want, wish等只能用動(dòng)詞不定式作賓語(yǔ)
口訣（接不定式作賓語(yǔ)的動(dòng)詞）
想要學(xué)習(xí) 早打算（ want learn plan）
快準(zhǔn)備 有希望（ prepare hpe wish expect）
同意否 供選擇（agree ffer chse）
決定了 已答應(yīng)（decide be deterined prise）
盡力去 著手做（anage undertae）
別拒絕 別假裝（refuse pretend）
失敗不是屬于你（fail）
e.g.T refused t lend e his pen.
We hpe t get there befre dar.
The girl decided t d it herself.

理解賓語(yǔ)從句的時(shí)態(tài)響應(yīng)，應(yīng)注意以下幾種情況：
1. 無(wú)需呼應(yīng)的情況：若主句謂語(yǔ)動(dòng)詞的時(shí)態(tài)為現(xiàn)在時(shí)或?qū)?lái)時(shí)，賓語(yǔ)從句的謂語(yǔ)動(dòng)詞可根據(jù)句意的需要使用任何所需要的時(shí)態(tài)。如：
He knows where they live. 他知道他們住哪里。
No one knows where he was born. 沒(méi)有人知道他出生于何地。
Tom says that he'll never get married. 湯姆說(shuō)他永遠(yuǎn)不結(jié)婚。
2. 主句為過(guò)去時(shí)的情況：若主句謂語(yǔ)動(dòng)詞為過(guò)去時(shí)，賓語(yǔ)從句的謂語(yǔ)動(dòng)詞應(yīng)用相應(yīng)的過(guò)去時(shí)態(tài)。如：
She asked me if I'd slept well. 她問(wèn)我睡得好不好。
I didn't know whether they liked the place. 我不知道他們是否喜歡這個(gè)地方。
He said he was going to accompany her home. 他說(shuō)他將陪她回家。
當(dāng)主句謂語(yǔ)動(dòng)詞為過(guò)去時(shí)，即使賓語(yǔ)從句所表示的時(shí)間是現(xiàn)在，通常也用過(guò)去時(shí)。如：
Oh！ I didn't know you were here. 啊！ 我不知道你在這里。(you were here指說(shuō)話的當(dāng)時(shí))
Hello！ I didn't know you were in London. How long have you been here？ 你好！ 我不知道你在倫敦。你來(lái)這里多久了？ (you were in London其實(shí)是指說(shuō)話的當(dāng)時(shí))
當(dāng)然，為避免誤會(huì)，我們也可以直接使用現(xiàn)在時(shí)態(tài)或?qū)?lái)時(shí)態(tài)來(lái)表示現(xiàn)在或?qū)?lái)要發(fā)生的`情況，而無(wú)需考慮與主句謂語(yǔ)的過(guò)去時(shí)相呼應(yīng)。如：
She said she'll be back tonight. 她說(shuō)她今晚回來(lái)。
He said that the meeting is Tuesday. 他說(shuō)會(huì)議于星期二舉行。
3. 從句為客觀真理的情況：當(dāng)賓語(yǔ)從句的內(nèi)容是客觀真理或客觀事實(shí)，可以不受時(shí)態(tài)呼應(yīng)的限制，即使主句謂語(yǔ)動(dòng)詞為過(guò)去時(shí)，從句仍用一般現(xiàn)在時(shí)。如：
The teacher told the students that light travels faster than sound. 老師告訴學(xué)生，光的速度比聲速快。
When we were children， we were told that China is in the east of the world. 我們還是小孩子的時(shí)候，人們就告訴我們說(shuō)中國(guó)在世界的東方。

條件狀語(yǔ)從句
引導(dǎo)詞：if(如果)，unless(除非)，if only(只要，但愿)，only if(只有)，in case(萬(wàn)一)，suppose/supposing(that)
(假設(shè))，provided/providing(that)(只要，假若)，on condition that(要是，在......條件下)，so/as long as(只要)，(let's/let us)say(假設(shè)) 方式狀語(yǔ)從句
引導(dǎo)詞：as(像......一樣，正如......)，as if/as though(好像，宛如) 注意：
1、固定句型A is to B what C is to D.意為“A對(duì)B而言正如C對(duì)D一樣”。
2、as if, as though引導(dǎo)的從句若與事實(shí)相反，用虛擬語(yǔ)氣;若與事實(shí)相符，不用虛擬語(yǔ)氣。
讓步狀語(yǔ)從句
引導(dǎo)詞：though/although/as(雖然，盡管)，even if/though(即使，盡管)，whether/no matter whether...or(not) (不管......是否，不管是......還是)whever/no matter wh-(無(wú)論......) 注意：
(1)though,although,as的區(qū)別
A、Though,although的主句中可以用yet, still, nevertheless,但不可使用but。
B、though引導(dǎo)的從句可以倒裝，也可以不倒裝;as引導(dǎo)的`從句必須倒裝;although引導(dǎo)的從句不能倒裝。
其結(jié)構(gòu)為：形容詞/分詞/副詞/動(dòng)詞原形/名詞(無(wú)冠詞)+as/though+主語(yǔ)+謂語(yǔ)……
(2)though可用作副詞，放在句末，意為“不過(guò)，但是”。Although無(wú)此用法。
(3)某些短語(yǔ)也引導(dǎo)讓步的從句或短語(yǔ)，意為“盡管”，如：in spite of the fact that, despite the fact that, regardless of(the fact that)

五、小學(xué)英語(yǔ)人稱代詞主格及賓格
人稱代詞分為主格和賓格，主格和賓格區(qū)別：主格和賓格漢語(yǔ)意思相同，但位置不同。
Eg:I(主格)"我"-- me (賓格)"我"
主格在陳述句中通常放句首，賓格通常放在動(dòng)詞后或介詞后，也就是說(shuō)賓格，不放在句首。

Excuse me (me 賓格)
I ask him to go (him 賓格)
They sit in front of me (me 賓格)

好這三個(gè)詞呢?請(qǐng)記住下列口決：
2、我是 am（ eg:I am a pupil.）
你是 are （eg:You are a girl.）
Is 用在他、她、它（eg:He is a Chinese boy,She is an English teather,It is a cat.見(jiàn)到復(fù)數(shù)就用are.）
3、記�。篴m ,is 的復(fù)數(shù)是are.;these 這些 ;those 那些(這兩個(gè)詞都表示復(fù)數(shù))
十、英語(yǔ)簡(jiǎn)縮形式的變法語(yǔ)法
1、簡(jiǎn)縮形式的變法：把倒數(shù)第二個(gè)字母，通常是元音字母變成' 但are除外，are要把a(bǔ)打成' 。Eg:he is=he's they are=they're

英語(yǔ)語(yǔ)法知識(shí)點(diǎn)12
1.(誤〕 Three days after he died. 正〕 After three days he died. 〔正〕 Three days later he died.〔析〕 after 與 later都可以用來(lái)表達(dá)一段時(shí)間之后，但它們所處的位置不同，after 在時(shí)間詞前，而later在時(shí)間詞后。
2.〔誤〕 She hid herself after the tree. 〔正〕 She hid herself behind the tree.〔析〕 after多用來(lái)表達(dá)某動(dòng)作之后，所以有的語(yǔ)法書中稱它為動(dòng)態(tài)介詞，如：I run after him. After finishing my homework, I went to see a film. 而behind則多用于靜態(tài)事物之后。
3.〔誤〕 There is a beautiful bird on the tree. 正〕 There is a beautiful bird in the tree.〔析〕 樹上長(zhǎng)出的果實(shí)，樹葉要用on, 而其他外來(lái)的人、物體均要用in the tree.
4.〔誤〕 Shanghai is on the east of China. 〔正〕 Shanghai is in the east of China.〔析〕 在表達(dá)地理位置時(shí)有3個(gè)介詞：in, on, to。 in表示在某范圍之內(nèi); on表示與某地區(qū)接壤;to則表示不相接。如：Japan is to the east of China.
5.〔誤〕 I arrived at New York on July 2nd. 〔正〕 I arrived in New York on July 2nd.〔析〕 at用來(lái)表達(dá)較小的地方，而in用來(lái)表達(dá)較大的地方。at常用于at the school gate, at home, at a bus stop, at the station, at the cinema, at a small village。
6.〔誤〕 He lived in No. 3 Beijing Road. 〔正〕 He lived at No. 3 Beijing Road.〔析〕 在門牌號(hào)碼前要用at, 并要注意它的慣用法：at the end of the street, at the foot of the mountain, at the top of the page。7.〔誤〕 There is a colour TV set at the corner of the hall. 〔正〕 There is a colour TV set in the corner of the hall.〔析〕 在屋內(nèi)的角落應(yīng)用in，而墻的`外角用at，如：There is a tree at the corner of the street.
8. 〔誤〕 Do you know there is some good news on todays newspaper? 〔正〕 Do you know there is some good news in todays newspaper? 〔析〕 在報(bào)紙上的新聞要用in, 而在具體某一版上，或某一頁(yè)上則要用on。
9. 〔誤〕 The school will begin on September 1st. 〔正〕 School will begin on September 1st.〔析〕這里的school應(yīng)看作不可數(shù)名詞泛指學(xué)校的課程，即開(kāi)學(xué)之意。要注意，有些活動(dòng)場(chǎng)所當(dāng)表達(dá)正在從事該種活動(dòng)時(shí)不要加冠詞，如：at table (吃飯)， When I came to Toms home, they were at table. 還有： at desk (學(xué)習(xí))，at work (工作) at school (上學(xué))， in hospital (住醫(yī)院) at church 作禮拜如加上定冠詞則另有他意，如：at the school 即在學(xué)校工作或辦事，in the hospital 即在醫(yī)院工作或去看望病人。
10. 〔誤〕 Ill leave Beijing to Shanghai tomorrow. 〔正〕 Ill leave Beijing for Shanghai. 〔正〕 Ill leave for Shanghai.〔析〕 leave for 是離開(kāi)某地去某處的固定搭配，不可將for改為別的介詞。這樣的搭配還有：start for 動(dòng)身前往某處，set out for， sail for。
英語(yǔ)語(yǔ)法知識(shí)點(diǎn)13
1：“first”是序數(shù)詞，與“the”相連，解釋為第一。
2：像“first，term，world”作為詞組出現(xiàn)時(shí)前面要加“the”。
3：“all”所有;后面的可數(shù)名詞用復(fù)數(shù)形式，be動(dòng)詞用“are”。
4：“any”一些;用在否定句和一般疑問(wèn)句中，與“some”同義�！皊ome”用在肯定句中。
5：there be+數(shù)詞，采用“就近原則”。
6：a map of China 與 a map of the world 要牢記。
7：要用“on the wall”，不能用“in the wall”。門、窗在墻上才能用“in the wall”。
8：can 后+動(dòng)詞原形。
9：play+the+樂(lè)器; play+球類;
10：like的用法
11：動(dòng)詞變動(dòng)名詞形式方法：
A--直接在動(dòng)詞后面+ing形式(大多數(shù))。
B--以不發(fā)音的“e”結(jié)尾的`，要去掉e后再+ing，比如：dancing，making，riding。
C--重讀be音節(jié)，末尾只有一個(gè)輔音，須雙寫末尾的字母后再+ing，如：running，swimming，sitting，putting。
12：現(xiàn)在進(jìn)行時(shí)的構(gòu)成：be動(dòng)詞+動(dòng)詞ing形式。標(biāo)志：now、look、listen、it's time to。
13：現(xiàn)在進(jìn)行時(shí)的一般疑問(wèn)句 /問(wèn)--be動(dòng)詞+人稱+時(shí)態(tài)(動(dòng)詞ing)
答--Yes，he/She/it is/am/are. No，he/She/it isn't/aren't/am not.
14：用Are you...? Yes,I am/ we are. No,I'm not/We aren't.
15: 動(dòng)詞后+人稱賓格形式.
16：一般現(xiàn)在時(shí)的構(gòu)成：第三人稱單數(shù)(三單)。要注意：后面的動(dòng)詞+s或es。
特例：have→has do→dose go→goes; 標(biāo)志：often，usually。
17：有些名詞變動(dòng)詞時(shí)要變形式，例如：teacher→teach;driver→drive.

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)潔句
3.引導(dǎo)表語(yǔ)從句的關(guān)聯(lián)詞的種類：
〔1〕附屬連詞that。如：The trouble is that I have lost his address.麻煩是我把他的地址丟了。
〔2〕附屬連詞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：附屬連詞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 its as if it was only yesterday.這都是20多年前的事了，但猶如昨天一樣。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、勸告、指令'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)。
