3、/was被強調(diào)部分that/who .句首詞用“it”；be動詞總是用單數(shù)形式，即is或was。連接詞一般用that，當強調(diào)部分是人時，強調(diào)連接詞也可用who。一、強調(diào)句的基本用法強調(diào)句就是把句中要強調(diào)的部分(通常是主語、賓語、狀語或狀語從句)放在It is/was和that/who之間，原句中剩余部分放在that/who之后。1強調(diào)句的陳述句式“It is/was被強調(diào)部分that/who其他剩余部分”The 2022 Winter Olympic Games will take place in Beijing and Zhangjiakou.It is in Beijing and Zh

4、angjiakou that the 2022 Winter Olympic Games will take place.在北京和張家口將要舉行2022年冬季奧運會。名師點津(1)強調(diào)句中的連接詞只用that(指人或物)或who(只指人)，且都不可省略。(2)強調(diào)句可以強調(diào)主語、賓語和狀語，但不能強調(diào)謂語，強調(diào)謂語動詞要用do/does/did動詞原形。He did write to you last week. 上周他確實給你寫了信。2強調(diào)句的一般疑問句式“Is/Was it被強調(diào)部分that/who其他剩余部分？”Is it in Beijing and Zhangjiakou that

5、the 2022 Winter Olympic Games will take place?是在北京和張家口將要舉行2022年冬季奧運會嗎？3強調(diào)句的特殊疑問句式“被強調(diào)的疑問詞is/was itthat其他剩余部分？”Whats it that Professor Liu teaches us this year?劉教授今年到底教我們什么？How is it that she turned down our help?什么原因使得她拒絕我們的幫助的？When and where was it that you got to know Mary?究竟在何時何地你認識的瑪麗？Who was it

6、 that came up with the bright idea? 究竟是誰提出了好的主意？4強調(diào)句的識別方法如果把強調(diào)結(jié)構(gòu)去掉，句子的意思是完整、清楚的，句子結(jié)構(gòu)也是完整的，這個句子就是強調(diào)句。如果把強調(diào)結(jié)構(gòu)去掉后，意思不通順，結(jié)構(gòu)也不完整，則句子不構(gòu)成強調(diào)句式。It was because he refused to obey the policeman that he was sent to the police station.他是因為拒絕服從警察而被送到警察局的。把強調(diào)結(jié)構(gòu)去掉，則變?yōu)椋篐e was sent to the police station because he re

7、fused to obey the policeman.因為他拒絕服從警察，所以被送到了警察局。去掉強調(diào)部分后，句子結(jié)構(gòu)和意義仍然完整，說明這是個強調(diào)句。即時演練1(1)句型轉(zhuǎn)換They met each other in that supermarket.

9、 that Mr. Smith got angry?二、強調(diào)句的特殊用法強調(diào)句與其他句型的結(jié)合，注意以下幾種用法：1強調(diào)句型與名詞性從句的結(jié)合句式特征為： 整個強調(diào)句型用作名詞性從句或者在強調(diào)句型中含有名詞性從句時，從句要用陳述語序。Do you know what it is that they will do next?你知道他們下一步究竟要做什么嗎？2強調(diào)句型與定語從句的結(jié)合句式特征為： 在強調(diào)句型的被強調(diào)部分或其他部分中找出一個先行詞，附上修飾該部分的定語從句，這樣整個句子結(jié)構(gòu)就變得非常復(fù)雜。應(yīng)特別注意不要混淆定語從句的關(guān)系詞和強調(diào)句型中的that/who部分。It was last

10、Spring when they worked together (when引導的定語從句) that they began to become good friends.是在一起工作的去年的春天里他們開始成為了好朋友。It was in the school where they had their schooling (where引導的定語從句) that they had a gettogether again twenty years later.二十年后，他們是在曾接受教育的學校里又聚在了一起。3強調(diào)句型與not . until句型的結(jié)合“It is/was not until被強調(diào)

11、部分that其他剩余部分”It was not until he came back that I knew the result.直到他回來，我才知道結(jié)果。即時演練2(1)單句語法填空The question is whom it is that we can turn to for help.

12、ry that counts.(2)補全句子Ive already forgotten where_it_was_that you put the dictionary.我已經(jīng)忘了你到底把字典放到哪里了。It_was_playing_computer_games_that cost the child plenty of time which he ought to have spent doing his lessons. 是玩電腦游戲花去了這個孩子大量的應(yīng)該用在功課上的時間。(2013天津高考改編)It_was_not_until_near_the_end_of_the_letter_th

13、at she mentioned her own plan.直到將近信的結(jié)尾她才提到她自己的計劃。三、強調(diào)句應(yīng)注意的問題1即使被強調(diào)成分是句中的時間狀語、地點狀語、原因狀語等，也不能用when, where, because等而要用that。It was in front of the bank that the old lady was robbed.老太太是在銀行前面被搶劫的。2強調(diào)句型中的主謂一致還原后，由真正的主語來確定謂語動詞的形式。Personally I think it is the sales manager, rather than the sales girls, tha

14、t _ to blame.強調(diào)句還原：Personally I think the sales manager, rather than the sales girls, _ to blame.根據(jù)主謂一致中的“就遠原則”可以判斷使用第三人稱單數(shù)；根據(jù)平行謂語動詞think，可以確定使用一般現(xiàn)在時，故此處應(yīng)為is。3強調(diào)句型的反意疑問句句式“It is/was被強調(diào)部分that/who ., isnt/wasnt it？”It was Alice and her boyfriend who sent the old man to the hospital, wasnt it?是愛麗絲和她的男朋

15、友把這老人送到醫(yī)院的，是嗎？4強調(diào)句型的省略形式句式特征為： 在一定的上下文中，強調(diào)句型的某個部分可以省略，解題時要特別注意將其復(fù)原并加以比較。Who is making so much noise in the garden?It is the children (who are making so much noise in the garden)是誰在花園里弄這么大的噪音？是孩子們。5易與強調(diào)句混淆的幾個句型(1)It is時間when .“當?shù)臅r候；時間是”when 引導的是時間狀語從句，主句中的 it 指時間，表語由具體的時間充當。試比較：It was ten oclock when

16、 we got home last night. 我們昨晚到家時十點了。(狀語從句)It was at ten oclock that we got home last night. 我們昨晚是在十點到家的。此句是強調(diào)句，去掉“It was . that”后句子仍然完整合理，注意that不能改成when。而上句不是強調(diào)句。(2)It was/will be . before . “過就”It was not/will not be . before . “不久就”主句中的 it 指時間，表語多是long, not long, three days, two weeks等表示“一段時間”的詞或短

17、語。試比較：It was three days before he went to Beijing. 三天后他就去了北京。It was three days ago that he went to Beijing. 他是三天前去的北京。此句是強調(diào)句，去掉“It was . that”后句子仍然完整合理。即時演練3單句語法填空(2015湖南高考書面表達)It is the teachers praise that contributes to my success.It is either he or you who are (be) in charge of the project and s
