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(rèn)為強(qiáng)調(diào)的
是原因狀語(yǔ)從句 because we were late.「分析」但實(shí)際上，此題的答案為B ，
強(qiáng)調(diào)的是句子主語(yǔ) our being late ，此題若還原成非強(qiáng)調(diào)句，即為：Our being
late caused him to serve dinner an hour later than usual. 注意，強(qiáng)調(diào)句
的一個(gè)顯著特點(diǎn)是，若去掉強(qiáng)調(diào)結(jié)構(gòu) it is [was]… that …，句子仍然成立；
換句話說(shuō)，該結(jié)構(gòu)中的 that 不能充當(dāng)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(gè)干擾項(xiàng)均可能誤選。

    「分析」答案選A ，為強(qiáng)調(diào)句的特殊疑問(wèn)句形式，其相應(yīng)的陳述句形式為：
It was totally by chance that they discovered the entrance to the underground
palace. 比較以下各題，它們也屬?gòu)?qiáng)調(diào)句的特殊疑問(wèn)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(qiáng)調(diào)成分為 who，該句實(shí)為類(lèi)
似 It was Tom that saved the drowning girl. 這類(lèi)強(qiáng)調(diào)句的特殊疑問(wèn)句形式
（即對(duì)其中的Tom 提問(wèn)而得）。

    （2 ） What is it _____ his daughter needs most ？

    A. what B. which C. that D. if答案選C ，被強(qiáng)調(diào)成分為 what ，該句實(shí)
為類(lèi)似 It is a bike that his daughter needs most. 這類(lèi)強(qiáng)調(diào)句的特殊疑問(wèn)
句形式（即對(duì)其中的a bike提問(wèn)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(gè)干擾項(xiàng)均有可能誤選，但最有可能誤選的可能是A ，認(rèn)為這是一個(gè)普通的系表
結(jié)構(gòu)，即認(rèn)為第二空要填形容詞作表語(yǔ)。

    「分析」其實(shí)，此題是一個(gè)強(qiáng)調(diào)句，其非強(qiáng)調(diào)形式為 Little Jim wrote the
letter very carefully.若用 it is… that …的強(qiáng)調(diào)句式強(qiáng)調(diào)其中的狀語(yǔ) very
carefully 即為上面一題的題干，所以答案應(yīng)選B.請(qǐng)看下面幾例，也屬?gòu)?qiáng)調(diào)結(jié)構(gòu)
：（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(qiáng)調(diào)成分為 when she was about
to go to bed這一時(shí)間狀語(yǔ)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(qiáng)調(diào)成分為 at Christmas ，
其中的動(dòng)詞 be 采用了 may have been這一較為復(fù)雜的形式。

    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(rèn)為這是一個(gè)強(qiáng)調(diào)句，強(qiáng)調(diào)
地點(diǎn)狀語(yǔ) 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(xué)生們通常是在大廳開(kāi)會(huì)”，
單獨(dú)看這一句，無(wú)論是其意思還是其語(yǔ)法均未錯(cuò)，但若將其與上文聯(lián)系起來(lái)看，
則不通，因?yàn)樯衔牡囊馑际?ldquo;你是在哪兒找到昨天作報(bào)告的那位教授的？”假若
將答句改為 It was in the hall that I found the professor，則完全可以。

    其實(shí)，此題的最佳答案是A ，where the students often have a meeting
為定語(yǔ)從句，用以修飾其前的名詞 the hall ，句意為“是在學(xué)生們經(jīng)常開(kāi)會(huì)的
那個(gè)大廳（找到教授的）”，這樣語(yǔ)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(gè)干擾項(xiàng)均有可能誤選。

    「分析」此題為一個(gè)強(qiáng)調(diào)句型，空格處應(yīng)填 that （即選D ），被強(qiáng)調(diào)成分
為 what he meant rather than what he said.句意為“讓我生氣的不是他說(shuō)的
話，而是他話中的意思”。請(qǐng)?jiān)倏磧衫�：�? ） It was his nervousness in the
interview ______ probably lost him the job. A. which B. since C. that
D. what 答案選C ，為強(qiáng)調(diào)句型，被強(qiáng)調(diào)成分為 his nervousness in the interview，
句意為“很可能是面試時(shí)表現(xiàn)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 ，為強(qiáng)
調(diào)句型，被強(qiáng)調(diào)成分為 the ability to do the job，句意為“重要的是你做工
作的能力，而不是你來(lái)自何地或你是從事什么工作的”。

    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(gè)干擾項(xiàng)均有可能誤選，主要是分不清為強(qiáng)
調(diào)句型，或即使分清為強(qiáng)調(diào)句型，也分不清強(qiáng)調(diào)哪一個(gè)成分。

    「分析」答案選A ，第一空填 which，用以引導(dǎo)定語(yǔ)從句；第二空填that，
為強(qiáng)調(diào)句的結(jié)構(gòu)詞，被強(qiáng)調(diào)部分為 in the small house （以及修飾它的定語(yǔ)從
句 which was built with stones by his father）。此題難就難在強(qiáng)調(diào)句型中
套用了定語(yǔ)從句。請(qǐng)?jiān)倏搭?lèi)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 ，全句為強(qiáng)調(diào)句，被強(qiáng)調(diào)成分是 the boy（以及
修飾它的定語(yǔ)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， thatD. which ， that 此題答案
選C ，全句為強(qiáng)調(diào)句，被強(qiáng)調(diào)成分是 in this room ，where he was born 為修
飾 the room 的定語(yǔ)從句。

    7. Was it five o'clock ______the fire broke out ？

    A. when B. that C. whichD. in which 「陷阱」容易誤選B ，誤認(rèn)為這是
強(qiáng)調(diào)句。

    「分析」其實(shí)，此題應(yīng)選A ，這不是強(qiáng)調(diào)句。因?yàn)樵趶?qiáng)調(diào)句中，若去掉強(qiáng)調(diào)
句的結(jié)構(gòu)詞 it is [was]…that…，句子結(jié)構(gòu)仍然完整，但此句不是這樣，若去
掉結(jié)構(gòu)詞，即為 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?yàn)?at five o'clock用作時(shí)間狀語(yǔ)。此題選A
可分析為：it表時(shí)間，when the fire broke out 為時(shí)間狀語(yǔ)從句，全句意為
“火災(zāi)是5 點(diǎn)鐘發(fā)生的嗎？”比較下面一題（答案選B ，為強(qiáng)調(diào)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(rèn)為這是強(qiáng)調(diào)句型。

    「分析」其實(shí)此題應(yīng)選D.做好此題的關(guān)鍵是正確理解上下文的語(yǔ)境。在此句
中，it是代詞，指代 the bike ，句意為：“當(dāng)你離開(kāi)去同朋友談話的時(shí)候，你
的自行車(chē)是在這樹(shù)下嗎？”“當(dāng)然，但當(dāng)我回來(lái)時(shí)，自行車(chē)就不見(jiàn)了。”現(xiàn)在反
過(guò)來(lái)分析一下，假若選A ，將此句判為強(qiáng)調(diào)句，句子即為 Was it under the tree
that you were away talking to a friend？若進(jìn)一步轉(zhuǎn)換為非強(qiáng)調(diào)句，句子則
為 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. sinceD. while「
陷阱」容易誤選B ，認(rèn)為這是強(qiáng)調(diào)句型。

    「分析」假若選B ，將此句分析為強(qiáng)調(diào)句，那么若將此句還原為非強(qiáng)調(diào)句就
應(yīng)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(shí)間，然而它修飾的謂語(yǔ)動(dòng)詞 joined …became卻是兩個(gè)終止性動(dòng)詞，這顯然
不合適。其實(shí)，此題應(yīng)選C ，屬于“It is ＋一段時(shí)間＋since 從句”句型，句
意為“我爺爺加入黨組織成為人民的公仆已有半個(gè)多世紀(jì)了”。此句的主句謂語(yǔ)
也可以用現(xiàn)在完成時(shí)態(tài)（has been），但在口語(yǔ)中多用一般現(xiàn)在時(shí)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(hào)的影響，
誤認(rèn)為這是一個(gè)非限制性定語(yǔ)從句，從而誤選了A.「分析」其實(shí)，此題最佳答案
為C ，整個(gè)句子為強(qiáng)調(diào)句，被強(qiáng)調(diào)成分為 lack of money， not of effort. 由
于句中插入 not of effort這一結(jié)構(gòu)，干擾了許多同學(xué)對(duì) it was lack of money
that defeated their plan這一強(qiáng)調(diào)句的認(rèn)識(shí)和理解。
