1. ____ that caused him to serve dinner an hour later than usual.
A. It was we being late B. It was our being late
C. It was we were too late D. It was because we were late
【陷阱】此題容易誤選D，認爲強調的是原因狀語從句 because we were late。
【分析】但實際上，此題的答案爲B，強調的是句子主語 our being late，此題若還原成非強調句，即爲：
Our being late caused him to serve dinner an hour later than usual.
注意，強調句的一個顯著特點是，若去掉強調結構 it is [was]… that…，句子仍然成立;換句話說，該結構中的 that 不能充當句子成分。
2. “How was ______ they discovered the entrance to the underground palace?” “Totally by chance.”
A. it that B. he that
C. it when D. he which
【陷阱】幾個干擾項均可能誤選。
【分析】答案選A，爲強調句的特殊疑問句形式，其相應的陳述句形式爲：
It was totally by chance that they discovered the entrance to the underground palace.
比較以下各題，它們也屬強調句的特殊疑問句形式：
(1) Who was it _____ saved the drowning girl?
A. since B. as C. that D. he
答案選C，被強調成分爲 who，該句實爲類似 It was Tom that saved the drowning girl. 這類強調句的特殊疑問句形式(即對其中的Tom 提問而得)。
(2) What is it _____ his daughter needs most?
A. what B. which C. that D. if
答案選C，被強調成分爲 what，該句實爲類似 It is a bike that his daughter needs most. 這類強調句的特殊疑問句形式(即對其中的a bike 提問而得)。
3. _____ was very ______ that little Jim wrote the letter.
A. It， careful B. It， carefully
C. He， careful D. He， carefully
【陷阱】幾個干擾項均有可能誤選，但最有可能誤選的可能是A，認爲這是一個普通的系表結構，即認爲第二空要填形容詞作表語。
【分析】其實，此題是一個強調句，其非強調形式爲 Little Jim wrote the letter very carefully. 若用 it is … that… 的強調句式強調其中的狀語 very carefully 即爲上面一題的題幹，所以答案應選B。請看下面幾例，也屬強調結構：
(1) It was when she was about to go to bed ______ the telephone rang.
A. since B. as C. that D. then
答案選C，被強調成分爲 when she was about to go to bed 這一時間狀語從句。
(2) It may have been at Christmas _____ John gave Mary a handbag.
A. before B. who C. that D. when
答案選C，被強調成分爲 at Christmas，其中的動詞 be 採用了 may have been 這一較爲複雜的的形式。
4. “Where did you find the professor who made the speech yesterday?” “It was in the hall ______ the students often have a meeting.”
A. where B. which
C. that D. when
【陷阱】很可能誤選C，認爲這是一個強調句，強調地點狀語 in the hall。
【分析】假若選C，即有 It was in the hall that the students often have a meeting，該句的意思是“學生們通常是在大廳開會”，單獨看這一句，無論是其意思還是其語法均未錯，但若將其與上文聯繫起來看，則不通，因爲上文的意思是“你是在哪兒找到昨天作報告的那位教授的?”假若將答句改爲 It was in the hall that I found the professor，則完全可以。
其實，此題的最佳答案是A，where the students often have a meeting 爲定語從句，用以修飾其前的名詞 the hall，句意爲“是在學生們經常開會的那個大廳(找到教授的)”，這樣語意就通順了。
5. It was what he meant rather than what he said ______ annoyed me.
A. which B. as
C. what D. that
【陷阱】幾個干擾項均有可能誤選。
【分析】此題爲一個強調句型，空格處應填 that (即選D)，被強調成分爲 what he meant rather than what he said。句意爲“讓我生氣的不是他說的話，而是他話中的意思”。請再看兩例：
(1) It was his nervousness in the interview ______ probably lost him the job.
A. which B. since C. that D. what
答案選C，爲強調句型，被強調成分爲 his nervousness in the interview，句意爲“很可能是面試時表現出緊張，使他失去了這份工作”。
(2) It is the ability to do the job ______ matters not where you come from or what you are.
A. one B. that C. what D. it
答案選B，爲強調句型，被強調成分爲 the ability to do the job，句意爲“重要的是你做工作的能力，而不是你來自何地或你是從事什麼工作的”。
6. It was in the small house ______ was built with stones by his father ______ he spent his childhood.
A. which， that B. that， which
C. which， which D. that， where
【陷阱】幾個干擾項均有可能誤選，主要是分不清爲強調句型，或即使分清爲強調句型，也分不清強調哪一個成分。
【分析】答案選A，第一空填 which，用以引導定語從句;第二空填that，爲強調句的結構詞，被強調部分爲 in the small house (以及修飾它的定語從句 which was built with stones by his father)。此題難就難在強調句型中套用了定語從句。請再看類似例子：
(1) It was the boy _____ had been in prison _____ stole the money.
A. who， where B. that， how
C. who， that D. that， which
此題答案選C，全句爲強調句，被強調成分是 the boy (以及修飾它的定語從句who had been in prison)。
(2) It was just in the room ____
_ he was born _____ he died.
A. where， which B. that， that
C. where， that D. which， that
此題答案選C，全句爲強調句，被強調成分是 in this room，where he was born 爲修飾 the room 的`定語從句。
7. Was it five o’clock ______the fire broke out?
A. when B. that
C. which D. in which
【陷阱】容易誤選B，誤認爲這是強調句。
【分析】其實，此題應選A，這不是強調句。因爲在強調句中，若去掉強調句的結構詞 it is [was]…that…，句子結構仍然完整，但此句不是這樣，若去掉結構詞，即爲 Five o’clock the fire broke out，句子不完整，但若在five o’clock前加上介詞at則可以，因爲 at five o’clock 用作時間狀語。此題選A可分析爲：it 表時間，when the fire broke out 爲時間狀語從句，全句意爲“火災是5點鐘發生的嗎?”比較下面一題(答案選B，爲強調句)：
Was it at five o’clock ______the fire broke out?
A. when B. that
C. which D. in which
8. “Was it under the tree _____ you were away talking to a friend?” “Sure. But when I got back there， the bike was gone.
A. that B. where
C. which D. while
【陷阱】此題很容易誤選A，認爲這是強調句型。
【分析】其實此題應選D。做好此題的關鍵是正確理解上下文的語境。在此句中，it 是代詞，指代 the bike，句意爲：“當你離開去同朋友談話的時候，你的自行車是在這樹下嗎?”“當然，但當我回來時，自行車就不見了。”現在反過來分析一下，假若選A，將此句判爲強調句，句子即爲 Was it under the tree that you were away talking to a friend? 若進一步轉換爲非強調句，句子則爲 Under the tree while you were talking to a friend，句意顯然很荒唐。
9. It’s more than half a century _____ my grandfather joined the Party and became a servant to the people.
A. when B. that
C. since D. while
【陷阱】容易誤選B，認爲這是強調句型。
【分析】假若選B，將此句分析爲強調句，那麼若將此句還原爲非強調句就應該是My grandfather joined the Party and became a servant to the people more than half a century. 很顯然， 句中的 more than half a century 是一段時間，然而它修飾的謂語動詞 joined…became 卻是兩個終止性動詞，這顯然不合適。其實，此題應選C，屬於“It is+一段時間+since 從句”句型，句意爲“我爺爺加入黨組織成爲人民的公僕已有半個多世紀了”。此句的主句謂語也可以用現在完成時態(has been)，但在口語中多用一般現在時代替。
10. It was lack of money， not of effort， _____ defeated their plan.
A. which B. as
C. that D. what
【陷阱】容易誤選A，受空格前逗號的影響，誤認爲這是一個非限制性定語從句，從而誤選了A。
【分析】其實，此題最佳答案爲C，整個句子爲強調句，被強調成分爲 lack of money， not of effort。由於句中插入 not of effort 這一結構，干擾了許多同學對 it was lack of money that defeated their plan 這一強調句的認識和理解。
