高三英語語法知識點1
強調(diào)句句型
1. 陳述句的強調(diào)句型:It is/ was + 被強調(diào)部分(通常是主語、賓語或狀語)+ that/ who(當強調(diào)主語且主語指人)+ 其他部分。
e.g. It was yesterday that he met Li Ping.
2. 一般疑問句的強調(diào)句型:同上,只是把is/ was提到it前面。
e.g. Was it yesterday that he met Li Ping?
3. 特殊疑問句的強調(diào)句型:被強調(diào)部分(通常是疑問代詞或疑問副詞)+ is/ was + it + that/ who + 其他部分?
e.g. When and where was it that you were born?
4. 強調(diào)句例句:針對I met Li Ming at the railway station yesterday.句子進行強調(diào)。
強調(diào)主語:It was I that (who) met Li Ming at the railway station yesterday.
強調(diào)賓語:It was Li Ming that I met at the railway station yesterday.
強調(diào)地點狀語:It was at the railway station that I met Li Ming yesterday.
強調(diào)時間狀語:It was yesterday that I met Li Ming at the railway station.
5. 注意:構(gòu)成強調(diào)句的it本身沒有詞義;強調(diào)句中的連接詞一般只用that, who,即使在強調(diào)時間狀語和地點狀語時也如此,that, who不可省略;強調(diào)句中的時態(tài)只用兩種,一般現(xiàn)在時和一般過去時。原句謂語動詞是一般過去時、過去完成時和過去進行時,用It was …… ,其余的時態(tài)用It is …… .
二、not … until … 句型的強調(diào)句
1. 句型為:It is/ was not until + 被強調(diào)部分 + that + 其他部分
e.g. 普通句:He didn't go to bed until/ till his wife came back.
強調(diào)句:It was not until his wife came back that he went to bed.
2. 注意:此句型只用until,不用till.但如果不是強調(diào)句型,till, until可通用;因為句型中It is/ was not …… 已經(jīng)是否定句了,that后面的從句要用肯定句,切勿再用否定句了。
三、謂語動詞的強調(diào)
1. It is/ was …… that …… 結(jié)構(gòu)不能強調(diào)謂語,如果需要強調(diào)謂語時,用助動詞do/ does或did.
e.g. Do sit down. 務(wù)必請坐。
He did write to you last week. 上周他確實給你寫了信。
Do be careful when you cross the street. 過馬路時,務(wù)必(千萬)要小心啊!
2. 注意:此種強調(diào)只用do/ does和did,沒有別的形式;過去時用did,后面的謂語動詞用原形。

as, though, although引導(dǎo)的讓步狀語從句。
[注意]although位于句首;though位于句首或句中;as位于句中=though。它的詞序是把句中強調(diào)的形容詞、副詞、動詞或名詞放在連詞前。[參考倒裝結(jié)構(gòu)] 請注意下列句式的變化:
[例句]
1. Although/Though I'm young, I already know what career I want to follow.
→Young as/though I am, I already know what career I want to follow.
我雖然年輕,但我已經(jīng)明白我應(yīng)該追隨什么樣的事業(yè)。
2. Although/Though I respect him very much, I cannot agree with his idea.
→Much as/though I respect him, I cannot agree with his idea. 雖然我很尊重他,但是我不同意他的觀點。
3. Although/Though he is a child, he knows a lot of Chinese characters.
→Child(省略冠詞)as/though he is, he knows a lot of Chinese characters. 他雖然還是個孩子,卻認識了許多漢字。
4. Although he tried, he couldn't solve the problem.
→Try as he might, he couldn't solve the problem. 盡管他努力了,但是他沒有解決問題。
5. Although it is raining, I'm going out for a walk.
→Raining as it is, I'm going out for a walk. 天雖然在下雨,我還是要出去散步。
6. Strange as it may seem, nobody was injured in the accident. 這次意外雖然顯得不可思議,卻沒有人受傷。
7. Much as I would like to help, I have a lot to do. 雖然我很想幫助你,但是我有很多事要做。
8. Object as you may, I will go. 縱使你反對,我也要去。

反意疑問句中的易錯點
1.在一般疑問句中,無論肯定的問或是否定的問,如果回答為肯定則用yes,反之則用no.特別注意如果出現(xiàn)省略則看下文所暗示的意義。?
①—Are?you?a?new?comer??
—Yes,?I?came?here?only?yesterday.?
②—Isn’t?Tom?a?good?student??
—Yes,?he?is?excellent.?
③—Don’t?you?think?the?composition?good??
—No,?It?can’t?be?any?worse.?
注意:在②③句中,當回答的意思與問句相一致時,則用No,譯為“是的”,當回答的意思與問句相反時,則用Yes,譯為“不”??
2.情態(tài)動詞must?
①?I?must?leave?now,?mustn’t?I???
②?He?must?be?in?the?classroom,?isn’t??(表推測)?
③?He?must?have?finished?his?homework,?hasn’t?he???(表現(xiàn)在的結(jié)果)?
④?He?must?have?finished?his?homework?yesterday?afternoon,didn’t?he??(表過去)?
當句子中有表示猜測的情態(tài)動詞時,其反意疑問句的構(gòu)成不能再用原句中的情態(tài)動詞,而應(yīng)根據(jù)原句在去掉情態(tài)動詞的情況下的主謂關(guān)系來確定其反問形式。??

名詞性從句的幾個難點
(一)that不可省略的情況
1、主語從句,that從句置于句首時;
2、當一個句子有兩個或多個并列的賓語從句時,引導(dǎo)第二和以后幾個從句的that不可省略;
3、由it作形式賓語時,that引導(dǎo)的賓語從句中,that不可以省略。
(二)wh-ever與no matter wh-的用法區(qū)別
Wh-ever既可引導(dǎo)名詞性從句,又可引導(dǎo)讓步狀語從句;而no matter wh-只能引導(dǎo)讓步狀語從句。
(三)as if/though, because, why可以引導(dǎo)表語從句
注意:because引導(dǎo)的表語從句,主語不能是reason或cause,而且since,as不能引導(dǎo)表語從句。
(四)that引導(dǎo)的同位語從句與關(guān)系代詞that引導(dǎo)的定語從句的區(qū)別
That引導(dǎo)的同位語從句成分是完整的,that在從句中不擔當任何成分;that引導(dǎo)的定語從句成分是殘缺的,that在從句中充當主語、賓語或表語。

助動詞
1)協(xié)助主要動詞構(gòu)成謂語動詞的詞叫助動詞。被協(xié)助的動詞稱作主要動詞。助動詞自身沒有詞義,不可單獨使用。例如:
He doesn′t like English. 他不喜歡英語。
(doesn′t是助動詞,無詞義;like是主要動詞,有詞義)
2) 助動詞協(xié)助主要動詞完成以下功用,可以用來:
a. 表示時態(tài)。例如:
He is singing. 他在唱歌。(北京安通學(xué)校提供)
He has got married. 他已結(jié)婚。
b. 表示語態(tài)。例如:
He was sent to England. 他被派往英國。
c. 構(gòu)成疑問句。例如:
Do you like college life? 你喜歡大學(xué)生活嗎?
Did you study English before you came here? 你來這兒之前學(xué)過英語嗎?
d. 與否定副詞not合用,構(gòu)成否定句。例如:
I don′t like him. 我不喜歡他。
e. 加強語氣。例如:
Do come to the party tomorrow evening. 明天晚上一定來參加晚會。
He did know that. 他的確知道那件事。
3) 最常用的助動詞有:be, have, do, shall, will, should, would等。
3 助動詞be的用法
1) be +現(xiàn)在分詞,構(gòu)成進行時態(tài)。例如:
They are having a meeting. 他們正在開會。
English is becoming more and more important. 英語現(xiàn)在越來越重要。(北京安通學(xué)校提供)
2) be + 過去分詞,構(gòu)成被動語態(tài)。例如:
The window was broken by Tom.. 窗戶是湯姆打碎的。
