1、“It is/was + 被強調(diào)部分 + that/who + 句子其他部分”是強調(diào)句型。除了謂語動詞不能強調(diào)外，句子中其它成分都可以用該句型加以強調(diào)。一、強調(diào)句型的功能：1. 強調(diào)主語被強調(diào)的主語是人時，可用it is/was . that/ who .，但如果被強調(diào)的部分既包括人又包括物，只能用that。It is Wei Fang who has broken the record. 是魏方打破了紀錄。2. 強調(diào)賓語It was me that she helped yesterday. 昨天她幫助的人是我。3. 強調(diào)賓語補足語It was chairman of the meeting

2、 that we elected him. 我們選他是做會議的主席。4. 強調(diào)狀語英語中的狀語種類很多,一般都可以用it is / was . that .來強調(diào)。 時間狀語It was at the age of 5 that he left his hometown for Taiwan.注意：如果強調(diào)由notuntil/till 引導(dǎo)的時間狀語時，要否定前移。如：It was not until after liberation that he returned to his hometown. 頻率狀語It is once in a while that he comes to see

3、 me. 地點狀語It was in this street that the car accident happened yesterday. 方式狀語It was by turns that they took care of their sick mother. 目的狀語It was to catch the early bus that he got up early. 原因狀語It was because the water had risen that they could not cross the river.二、強調(diào)句的一般疑問句和特殊疑問句1. 強調(diào)句的一般疑問句句型是：I

4、s/Was + it + that +句子其它成分。如：Was it in the office that he saw you just now？他剛才見你的地方是在辦公室嗎？2. 強調(diào)句的特殊疑問句的基本句型是：疑問詞+ is/was + it + that + 句子其它成分。如：When was it that you first went to the Great Wall？你究竟什么時候第一次去長城的？即學(xué)即練：翻譯下列句子1. 是他昨天買了一架照相機。2. 他們經(jīng)常談?wù)摰氖菍W(xué)校和老師。3. 我們把墻漆成的是白色。4. 他經(jīng)常去的地方是圖書館嗎？5. 究竟是誰告訴你這件事的？Key：

Is it the library that he often goes to?5. Who was it that told you about it?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(dāng)強調(diào)主語且主語指人）+

6、 其他部分。 例子 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。 例子 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？ 例子 When and where was it that you were born? 4.not until 句型的強調(diào)句 A. 句型為：It is/ was not until + 被強調(diào)部分 + that +

7、 其他部分 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. B. 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。 5.謂語動詞的強調(diào) A. 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

8、 Do sit down. 務(wù)必請坐。 Do be careful when you cross the street. 過馬路時，務(wù)必（千萬）要小心??！ B. 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。 編輯本段強調(diào)形式常見到的強調(diào)形式，共有以下七類： 用dodoesdid + V可表強調(diào) Some people do believe that nuclear power poses a threat to the world peace. adv或adj可表強調(diào)：Never only Very This is the very que

9、stion that deserves careful analysis. 雙重否定可表強調(diào) Taking part-time jobs is never without drawbacks. what引導(dǎo)的主從可表強調(diào) What really matters is cooperation. 倒裝可表強調(diào)(凡是倒裝都可以表示強調(diào)) Little do people take into account the seriousness of this problem. 比較狀語從句可表強調(diào) Nothing is more imperative than to learn from the past

10、. 強調(diào)句型可表強調(diào) It is was +被強調(diào)部份+ that who +原句剩余部份 It is stability that destroys peoples ambition and barricades peoples steps. 編輯本段語法結(jié)構(gòu)強調(diào)句的十種結(jié)構(gòu)： 1用助動詞“do（does/did）+動詞原形”來表示強調(diào)： Do write to me when you get there你到那兒后務(wù)必給我來信。 2用形容詞very，only，single，such等修飾名詞或形容詞來加強語氣： How dare you buy such expensive jewels？你

11、怎么敢買這么貴的寶石呢？ 3用ever，never，very，just等副詞和badly，highly，really等帶有l(wèi) y的副詞來進行強調(diào)： I really dont know what to do next我的確不知道下一步該怎么做。 4用in the world，on earth，at all等介詞短語可以表達更強的語氣（常用于疑問句）： Where in the world could he be？他到底會在哪兒？ 5用感嘆句來表示強烈的感情，突出說話人的情感： How interesting a story it is！這是一個多么有趣的故事??！ 6用重復(fù)來表示強調(diào)： Why！

23、erful. Its years _ I enjoyed myself much. A. after B. before C .that D. since 從句辨析 強調(diào)句將句子中的it is / was that同時省去，句子仍然成立；而主語從句將that與后面部分代替it，成立。如： (1) It is Li Leis brother that you met in the street yesterday. 你昨天在街上所見到的就是李蕾的兄弟。 本句若將It is 及 that同時省去為：You met Li Leis brother in the street yesterday. 句

24、子同樣成立，因此前面的句子是強調(diào)句型。 (2) It is exciting that we have succeeded in sending up Shenzhou V. 我們成功地發(fā)射了神舟五號這件事情真令人興奮。 本句若將It is 及 that同時省去為：We have succeeded exciting in sending up Shenzhou V. 顯然句子錯誤，因此，前面句子不是強調(diào)句型，而是主語從句。 與定語從句的比較強調(diào)句中的It沒有實際意義，It be與that可同時被省略；而定語從句中的It是主語，It be與that不可同時省略； 強調(diào)句型中be的時態(tài)須跟后面句

25、子的時態(tài)相一致；而定語從句中主句謂語動詞be的時態(tài)須由主句的時間確定 強調(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，也不能將that換成which；而定語從句中的that作賓語時可被省略，并且當(dāng)先行詞是事物時可用which代替。 當(dāng)it be后面的時間、地點名詞作主語、賓語或表語時，引導(dǎo)詞可用that / which；而作其他成分時，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What is that?問句的回答，that所引導(dǎo)的是定語從句，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I bought the English book yesterday中an English book進行強調(diào)) (2) It was a room where we used to have meetings. 它是我們過去常在開會的房子。(where 所引導(dǎo)的從句對前面的room進行說明，它是
