強調句基本定義
強調句(The Emphatic Pattern)是一種修辭，是人們為了表達自己的意願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是"It is (was)+被強調部分(主語、賓語或狀語)+who (that)..."。一般說來,被強調部分指人時,用who;指事物時用that,但that也可以指人。在美國英語中指事物時常用which來代替that。
常用句型
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）+ 其他部分。
例子 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。
例子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 + 其他部分？
例子When and where was it that you were born?
4.not … until … 句型的強調句
A. 句型為：It is/ was not until + 被強調部分 + that + 其他部分
普通句：He didn't 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.
B. 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後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
A. 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
Do sit down. 務必請坐。
Do be careful when you cross the street. 過馬路時，務必（千萬）要小心啊！
B. 注意：
此種強調只用do/ does和did，沒有別的形式；過去時用did，後面的謂語動詞用原形。
強調形式
常見到的強調形式，共有以下七類：
⒈用do\does\did + V可表強調
Some people do believe that nuclear power poses a threat to the world peace.
⒉adv或adj可表強調：Never \ only\ Very
This is the very question that deserves careful analysis.
⒊雙重否定可表強調
Taking part-time jobs is never without drawbacks.
⒋what引導的主從可表強調
What really matters is cooperation.
⒌倒裝可表強調(凡是倒裝都可以表示強調)
Littlie do people take into account the seriousness of this problem.
⒍比較狀語從句可表強調
Nothing is more imperative than to learn from the past.
⒎強調句型可表強調
It is \was +被強調部份+ that \ who +原句剩餘部份
It is stability that destroys people’s ambition and barricades people’s steps.
語法結構
強調句的十種結構：
1．用助動詞“do（does／did）＋動詞原形”來表示強調：
Do write to me when you get there．你到那兒後務必給我來信。
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 y的副詞來進行強調：
I really don’t 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（常用於疑問句）：
Where in the world could he be？他到底會在哪兒？
How interesting a story it is！這是一個多么有趣的故事啊！
6．用重複來表示強調：
Why！why！The cage is empty！啊！啊！箱子是空的。
7．用倒裝句（也就是將要強調的句子或被強調的部分置於句首）來加強語氣：
On the table were some flowers．桌上擺著一些花。（強調地點）
8．用強調句型：“It is（was）＋被強調的部分＋that（who）＋原句其它部分”來強調說話人的意願：
It was on Monday night that all this happened．所有這一切發生在周一晚上。
1）If從句＋I don’t know who／what，etc．does／is／has，etc．
主語部分也可以用nobody does／is／has，etc．或everybody does／is／has，et c．來代替（這裡的if從句往往是正話反說，反話正說）：
If he can’t do it，I don’t know who can．要是他做不了這件事，我不知道還有誰能做。（強調只有他能做） If Jim is a coward，everybody is．要是吉姆是個膽小鬼，那么人人都是膽小鬼。（強調吉姆不是膽小鬼）
2）if從句＋it be主句（此用法可看成是第8中強調句型的變形，即把所要強調的內容放在it be的後面，把其它內容放在由if引導的從句中）：
If anyone knew the truth，it was Tom．如果說誰了解事實的真相，那便是湯姆。
It’s because of hard work—ten years of hard work．那是因為艱苦的工作--十年艱苦的工作！
He began the work in late May．他在五月底開始的這項工作。（強調時間）

【答案與解析】
1. A。該句強調時間狀語。判斷是否是強調結構的方法是：將 it is卼hat 三個詞去掉，句子(有時要調整順序)依然正確，就是強調結構，否則就不是。
2. B。強調時間狀語從句。
3. B。強調的是主語。
4. B。對強調結構的一般問句的回答，若是過去式用 Yes, it was. 或 No, it wasn’t.
5. A。強調賓語(you)。強調結構的一般問句是：Was / Is it+被強調部分+that+句子的其他部分？強調結構的特殊問句是：疑問詞+was / is it that+句子的其他部分？如 When was it that you came back?
6. A。強調 what 引導的主語從句。
7. B。強調主語。
8. B。It was…that…是強調結構。此結構可強調除謂語外的任何一個句子成分，該句強調的是how引導的主語從句。
9. C。強調的是作原因狀語的介詞短語。
10. C。因為not…until…的強調結構是：it be not until…that…(肯定)。也不要用倒裝，故選C。順便說說，也可用not until開頭來強調，此時要倒裝，請比較：Not until midnight did he went back…。
11. A。考查強調結構的特殊問句的句式。因為及物動詞say要接賓語，排除C和D; 這是一個疑問句，所以is要放在it之前，排除B，只有A正確。
12. D。因為It wasn’t until…that…是not…until…的強調結構。
13. A。強調結構，強調的是主語從句。
14. C。強調結構，由答語可知，應當用how。
注意事項
that後的強調句如果是原因狀語從句，從句只能用because引導，不能用since，as或why。
Itwasbecausethewaterhadrisenthattheycouldnotcrosstheriver。

從句辨析強調句將句子中的itis/was…that同時省去，句子仍然成立；而主語從句將that與後面部分代替it，成立。如：
(1)ItisLiLei’sbrotherthatyoumetinthestreetyesterday.你昨天在街上所見到的就是李蕾的兄弟。
本句若將Itis及that同時省去為：YoumetLiLei’sbrotherinthestreetyesterday.句子同樣成立，因此前面的句子是強調句型。
(2)ItisexcitingthatwehavesucceededinsendingupShenzhouV.我們成功地發射了神舟五號這件事情真令人興奮。
本句若將Itis及that同時省去為：WehavesucceededexcitinginsendingupShenzhouV.顯然句子錯誤，因此，前面句子不是強調句型，而是主語從句。
與定語從句的比較
◎強調句中的It沒有實際意義，Itbe與that可同時被省略；而定語從句中的It是主語，Itbe與that不可同時省略；
◎強調句型中be的時態須跟後面句子的時態相一致；而定語從句中主句謂語動詞be的時態須由主句的時間確定
◎強調句將句子中的that不能省略，並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，並且當先行詞是事物時可用which代替。
◎當itbe後面的時間、地點名詞作主語、賓語或表語時，引導詞可用that/which；而作其他成分時，引導詞須用when/which。如：
(1)ItisanEnglishbook(that/which)Iboughtyesterday.它是我昨天買的書。(本句是對Whatisthat?問句的回答，that所引導的是定語從句，that可被省略)
ItwastheEnglishbookthatIboughtyesterday.昨天我所賣的就是這本書。(本句相當於對IboughttheEnglishbookyesterday中anEnglishbook進行強調)
(2)Itwasaroomwhereweusedtohavemeetings.它是我們過去常在開會的房子。(where所引導的從句對前面的room進行說明，它是定語從句)
Itwasintheroomthatweusedtohavemeetings.過去我們開會就在這間房子裡。(intheroom是被強調的部分，本句是強調句型)
(3)Itisadaywhenthepeoplecelebratetheirvictory.這是人們慶祝他們的勝利的日子。(when所引導的從句對aday進行說明，是定語從句)
Itwasonthatdaythatpeoplecelebratedtheirvictory.就在那一天，人們慶祝了他們的勝利。(強調onOctober1,1949)
與狀語從句的比較
◎狀語從句句首的It本身就是句子的主語；而強調句首的It不作任何成分也沒有實際意義。
◎狀語從句的連線副詞that及句子前面的Itbe不能去掉
◎狀語從句的引導詞可以是when/where，而強調句型中的that不能用其他詞代替。如：
(1)Itissuchaninterestingbookthatwealllikeitverymuch.它是一本如此有趣的書，我們大家都非常喜歡。(結果狀語主從複合句)
Itissuchaninterestingbookthatwealllikeverymuch.我們大家都非常喜歡的就是一本如此有趣的書。(強調suchaninterestingbook)
(比較：Itissuchaninterestingbookaswealllikeverymuch.這就是我們大家都非常喜歡的有趣的書。定語從句)
(2)Itwasalreadymorningwhenhewokeup.當他醒來時，已經是早晨了。(時間主從複合句)
Itwasthenextmorningthathewokeup.就在第二天早晨他醒來了。(強調thenextmorning)
