英語語法強調句知識點
漫長的學習生涯中，不管我們學什么，都需要掌握一些知識點，知識點是指某個模塊知識的重點、核心內容、關鍵部分。相信很多人都在為知識點發愁，下面是小編精心整理的英語語法強調句知識點，希望對大家有所幫助。
英語語法強調句知識點：有關強調結構的幾類重要考點
強調句型的基本結構是“It+be+被強調成分+that (who)…”。如：
He bought the book in this shop yesterday.
→It was he that bought the book in this shop yesterday. (強調主語he)
→It was the book that he bought in this shop yesterday. (強調賓語the book)
→It was in this shop that he bought the book yesterday. (強調地點狀語in this shop)
綜觀近幾年的語法考題，我們發現對強調句型的考查主要集中在以下幾個方面：
一、考查強調句的基本形式
這類考題主要涉及被強調成分為介詞短語的情形。如：
It’s in the park that Jack met your sister yesterday.
杰克昨天是在公園與你的姐姐見面的。
It is on political questions that their views are different.
他們在政治問題上見解不同。
【真題實例】
1. —Where did you get to know her?
—It was on the farm _________ we worked.
A. that B. there C. which D. where
2. David said that it was because of his strong interest in literature _________ he chose the course.
A. that B. what C. why D. how
(答案分別為DA)
二、考查強調句的特殊疑問句形式
強調句型的陳述句形式和一般疑問句形式一般還好理解，但若以特殊疑問句形式出現，則很容易誤解。比較：
Jim told us the news.(非強調句)
→It was Jim that told us the news.(強調句型的陳述句形式)
→Was it Jim that told us the news.(強調句型的一般疑問句形式)
→Who was it that told us the news.(強調句型的特殊疑問句形式)
特殊疑問句形式的強調句可視為對陳述句強調中的被強調成分提問得來，如對It was yesterday that he arrived. 這一句中的yesterday提問，即得到When was it that he arrived? 請再看以下例子：
How long ago is it that you last saw her? 你上一次看見她是多久以前的事?
Why is it that I always land up cleaning the bath? 為什么總是該我來洗刷浴缸?
Who was it that won the World Cup in 1982? 誰贏得了1982年的世界杯?
【真題實例】 (答案分別為DCA)
1. I just wonder _________ that makes him so excited.
A. why it does B. what he does C. how it is D. what it is
2.— _________ that he manage to get the information.
—Oh, a friend of his helped him.
A. Where was it B. What was it C. How was it D. Why was it
3. Why! I have nothing to confess. _________ you want me to say?
A. What is it that B. What it is that C. How is it that D. How it is that
三、考查被強調成分為從句的情形
如果被強調成分為一個詞或一個詞組還比較好理解，但如果被強調的是一個從句，則比較容易出錯。如：
It was after he got married that he got to know Mary.
他是在結婚之后才認識瑪麗的。
It was not what he he said but how he behaved that made us angry.
使我們生氣的不是他說的話，而是他做的樣子。
【真題實例】 (答案分別為CAAA)
1. It is not who is right but what is right _________ is of importance.
A. which B. it C. that D. this
2. I don’t mind her criticizing me, but _________ is how she does it that I object to.
A. it B. that C. this D. which
3. It was after he got what he had desired _________ he realized it was not so important.
A. that B. when C. since D. as
4. It is what you do rather than what you way _________ matters.
A. that B. what C. which D. this
朋友說話的時候它在這兒嗎?
四、考查not...until句式的強調結構
其基本形式為It is (was) not until…that…。比較：
He didnt come until his wife left. 他妻子走了之后他才來。
→It was not until his wife left that he came. 他妻子走了之后他才來。
They didnt start until the rain stopped. 直到雨停他們才出發。
→It was not until the rain stopped that they started. 直到雨停他們才出發。
注：這類句型不用倒裝語序，但若改成Not until…，則要用倒裝。如：
Not until his wife left did he come. 他妻子走了之后他才來。
Not until the rain stopped did they start. 直到雨停他們才出發。
【真題實例】 (答案分別為DBD)
1. It _________ we had stayed together for a couple of weeks _________ I found we had a lot in common.
A. was until; when B. was until; that C. wasn’t until; when D. wasn’t until; that
2. It was not until she got home _________ Jennifer realized she had lost her keys.
A. when B. that C. where D. before
3. It wasn’t until nearly a month later _________ I received the manager’s reply.
A. since B. when C. as D. that
五、考查強調句與非強調句的辨別
1. 設置陷阱，使考生將強調句誤判為非強調句。如：
It might have been John _________ bought a present for Mary yesterday.
A. that B. when C. what D. which
【解析】答案選A，為強調句型，由于句中動詞be采用了might have been這一復雜結構，所以許多同學們可能會看不出它是一個強調句型。
2. 設置陷阱，使考生將非強調句誤判為強調句。如：
It was evening we reached the little town of Winchester.
A. that B. until C. since D. before
【解析】答案選D。有的考生一看到句首的it was，再聯系到選項中的that，就以為這是考查強調句。其實錯了。此題是考查連詞before的用法。因為去掉It was…that這一結構后，原句不能成為一個完整的句子，所以這不是強調結構。句意是：我們還沒有到達Winchester這個小鎮，天就夜了。
英語語法強調句知識點：It is...that…句式通常不能強調哪些成分
有這樣一道考題：
It was a teacher that she __________.
A. was B. seemed C. looked D. married
此題應選D。從句意上看似乎4個選項都行，其實這里只能填D。因為填A，B，C 中的任意一個選項，都會導致句中的 a teacher成為表語，然而按照強調句句法規則，It is...that這一強調句型是不能強調表語的。一般說來，以下成分不能用于強調句中的被強調部分：
1. 表語：
她很美。
正：She is beautiful.
誤：It is beautiful she is.
他是醫生。
正：He is a doctor.
誤：It is a doctor that he is.
但是賓語補足語卻可以用作被強調部分：
他們選他擔任主席。
正：They elected him chairman.
正：It was chairman that they elected him.
2. since 和 as 引導的原因狀語從句(但 because 從句卻可以)：
他不能來是因為他病了。
正：It is because he is ill that he can’t come.
誤：It is since[as] he’s ill that he can’t come.
3. although 引導的讓步狀語從句：
雖然累了，但他還是去了。
正：He went although he was tired.
誤：It was although he was tired that he went.
英語語法強調句知識點：當心假強調句考點
【導語】英語語法讓很多學生都頭疼，因為復雜難懂的句式和詞組有時難以記憶。為大家整理了英語語法大全，希望對同學們的英語語法學習有所幫助。
有這樣一道題，它是考查強調句嗎?
It was 9 o’clock __________ he came back last night.
A. that B. when C. since D. this
此題應選 B。容易誤選 A，誤認為這是強調句型。假若這里填 that，構成強調句型，那么被強調的 9 o’clock 是什么成分呢(注意它不能作狀語)?但是若在 9 o’clock 前加一個介詞(at，after，before等)，則可以填 that 構成強調句。
試比較：
It was at ten o’clock that he came back. 他回來時是10點鐘。
It was after ten o’clock that he came back. 他是在10點過后回來的。
It was before ten o’clock that he came back. 他是在10點前回來的。
以上分析告訴我們，上題填 that 不對 (除非 9 o’clock前有介詞)。那么填 when 又作何解釋呢? 本題填 when，全句構成主從復合句，其中的when引導時間狀語從句(意為“當……的時候”)，全句意為：當他回來時，時間是晚上9點。
再請比較：
1. a. It is autumn when leaves fall. 當樹葉落的時 候就是秋天了。
b. It is in autumn that leaves fall. 樹在秋天落 葉。
2. a. It was lunchtime when he called. 當他來訪時，已是吃中飯的時候。
b. It was at lunchtime that he called. 他是在吃 中飯的時候來訪的。
強調句的概念：
強調句 (The Emphatic Pattern) 是一種修辭，是人們為了表達自己的意愿或情感而使用的一種形式。通過各種方式對句子中的某個部分進行強調，從而起到修辭的作用。英語常用的強調結構有：It is (was)+被強調部分(主語、賓語或狀語)+that/who...；what…be…句型；
強調句的使用:
一、強調句句型：
1、用It is／was...that／who...句型表示強調。
（1）陳述句的強調句型：It is/was+被強調部分（通常是主語、賓語或狀語）+that/who（當強調主語且主語指人）+其它部分。
e.g. It was yesterday that he met Li Ping.
�。�2）一般疑問句的強調句型：同上，只是把is/was提到it前面。
e.g. Was it yesterday that he met Li Ping?
�。�3）特殊疑問句的強調句型：被強調部分（通常是疑問代詞或疑問副詞）+is/was+it+that/who+其它部分？
e.g. When and where was it that you were born?
注：被強調的部分（通常是句子的主語、狀語、賓語或賓語補足語）放在is／was的后面，如被強調的是人，則后面可用who，whom等代替。
如：原句：He met an old friendin the park yesterday.
強調主語：It was he who/that met an old friendin the park yesterday.
強調賓語：It was an old friendthat/who he met in the park yesterday.
強調地點狀語：It was in the park that he met an old friendyesterday.
強調時間狀語：It was yesterday that he met an old friendin the park.
2、用助動詞do, does或did來強調謂語動詞。
如：Do come early.
He did sendyou a letter last week.
Were pleased that she does intendto come.
3、用主語從句+be+被強調部分，主語從句常用what引導。
如：What John wants is a ball.
What Mary does every day is(to) give piano lessons.
二、not...until...句型的強調句：
1、句型為：It is/was not until+被強調部分+that+其它部分：
e.g. 普通句：He didnt go to bed until/till his wife came back.
強調句：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。但如果不是強調句型，till, until可通用；
因為句型中It is/was not...已經是否定句了，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：
1、It is/was...that...結構不能強調謂語，如果需要強調謂語時，用助動詞do/does或did。
e.g. Do sit down.務必請坐。
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，務必（千萬）要小心�。�
2、注意：此種強調只用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。
使用強調句型有以下幾點請注意：
�、購娬{句的謂語is或was永遠用單數。
如：It was yesterday that I met your father in the street.
�、诓还鼙粡娬{部分是哪種狀語，只能用that連接，不得使用where、when等連詞。
如：It was in the street that I met your father yesterday.
�、郾粡娬{部分為人時，可用who(主格或賓格)和whom(賓格)代替that，用that也行。
如：It was your father that/whom/who I met in the street yesterday.
It was I that/who met your father in the street yesterday.
④強調句中也要注意主謂一致、人稱一致和否定轉移的問題。
如：It is they who are our friends.
It was not until ten oclock that we got home last night.
�、葑⒁獠灰煜龔娬{句和其他從句。It is/was...that...為強調句標志，去掉后仍可組成一個完整的句子，只是沒被強調，而其他從句一般不具備這一特征。
比較：1）It was ten oclock when we got home last night. 我們昨晚到家時已十點了。
2）It was at ten oclock that we got home last night. 我們昨晚是在十點到家的。
第一句不是強調句，when不可改為that，因為去掉it was和that后，只能組成“We got home ten oclock last night.”這樣一個不完整的句子；第二句是強調句，that不可改為when。
強調句型用法拓展：
1、句首詞用“It”，不能用“This”，“That”等。
2、be動詞的形式是is或was，不能用復數形式are或were。若原句的謂語動詞用了現在時或將來時，則用is；
若原句的謂語動詞用了過去時或過去完成時，則用was。
如：It___the Chinese women that___a great role in the socialist construction.
A. is; plays
B. are; play
C .is; play
D. are; plays
答案：C
3、被強調的部分如果是代詞，強調主語用主格，強調賓語用賓格。
如：It is him that/who/whom I met in the street yesterday.
It is I who/that am wrong.
4、連接詞一般用that，當強調部分是人時，既可用that也可用who。特別注意當強調部分是時間狀語或地點狀語時，不能用when或where。
如：It was on Oct1st, 1949 that Peoples Republic of China was founded.
It was at the gate____he told me the news.
A. that
B. what
C. which
D. when
答案：A
5、主謂一致問題被強調的主語要和that后面的謂語動詞在數上保持一致。
如：It is Mary who often _____(help) me with my English. （helps）
It is I that ____(be) against you. （am）
6、not...until結構的強調。
強調“not...until”引導的時間狀語時，要用“it is/was not until...that...”結構，that后面的句子要用肯定式，且須用陳述句語序。
如：We did not get off the bus until it stopped. ?
It was not until it stopped that we got off the bus. (注意：強調該結構時not until不能分開)
英語語法強調句的易錯點
一、關于結構中的that
此結構中，除強調的是作主語或賓語的人時可以用who外，其它任何情況都只能用that。如：
It was Kate that/who told me about it. 是凱特告訴那件事的。
It was yesterday afternoon that she told me about it. 是昨天下午她把那件事告訴我的。(that不能用when替代)
二、關于結構中be的形式
原句中謂語動詞是過去式，強調結構的be用is，原句謂語動詞是現在時或將來時，強調結構的be用was。如：
It is he that likes playing games. 是他喜歡打游戲。
It is tomorrow that we will have a meeting. 是明天我們要開會。
注：be有時與表示推測的情態動詞連用。如：
It must be John that/who cleaned the room. 一定是約翰打掃房間的。
三、關于主謂一致問題
被強調的是原句的主語時，要注意that/who后的謂語動詞與原句主語一致。如：
It is I that am in trouble. 是我陷入了困境。
