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】此题容易误选D，认为强调的是原因状语从句 because we were late。

【分析】但实际上，此题的答案为B，强调的是句子主语 our being late，此题若还原成非强调句，即为：

Our being late caused him to serve dinner an hour later than usual.

注意，强调句的一个显著特点是，若去掉强调结构 it is [was] that，句子仍然成立;换句话说，该结构中的 that 不能充当句子成分。

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】几个干扰项均可能误选。

【分析】答案选A，为强调句的特殊疑问句形式，其相应的陈述句形式为：

It was totally by chance that they discovered the entrance to the underground palace.

比较以下各题，它们也属强调句的特殊疑问句形式：

(1) Who was it _____ saved the drowning girl?

A. since B. as C. that D. he

答案选C，被强调成分为 who，该句实为类似 It was Tom that saved the drowning girl. 这类强调句的特殊疑问句形式(即对其中的Tom 提问而得)。

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

A. what B. which C. that D. if

答案选C，被强调成分为 what，该句实为类似 It is a bike that his daughter needs most. 这类强调句的特殊疑问句形式(即对其中的a bike 提问而得)。

3. _____ was very ______ that little Jim wrote the letter.

A. It, careful B. It, carefully

C. He, careful D. He, carefully

【陷阱】几个干扰项均有可能误选，但最有可能误选的可能是A，认为这是一个普通的系表结构，即认为第二空要填形容词作表语。

【分析】其实，此题是一个强调句，其非强调形式为 Little Jim wrote the letter very carefully. 若用 it is that 的强调句式强调其中的状语 very carefully 即为上面一题的题干，所以答案应选B。请看下面几例，也属强调结构：

(1) It was when she was about to go to bed ______ the telephone rang.

A. since B. as C. that D. then

答案选C，被强调成分为 when she was about to go to bed 这一时间状语从句。

(2) It may have been at Christmas _____ John gave Mary a handbag.

A. before B. who C. that D. when

答案选C，被强调成分为 at Christmas，其中的动词 be 采用了 may have been 这一较为复杂的形式。

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】很可能误选C，认为这是一个强调句，强调地点状语 in the hall。

【分析】假若选C，即有 It was in the hall that the students often have a meeting，该句的意思是学生们通常是在大厅开会，单独看这一句，无论是其意思还是其语法均未错，但若将其与上文联系起来看，则不通，因为上文的意思是你是在哪儿找到昨天作报告的那位教授的?假若将答句改为 It was in the hall that I found the professor，则完全可以。

其实，此题的最佳答案是A，where the students often have a meeting 为定语从句，用以修饰其前的名词 the hall，句意为是在学生们经常开会的那个大厅(找到教授的)，这样语意就通顺了。

5. It was what he meant rather than what he said ______ annoyed me.

A. which B. as

C. what D. that

【陷阱】几个干扰项均有可能误选。

【分析】此题为一个强调句型，空格处应填 that (即选D)，被强调成分为 what he meant rather than what he said。句意为让我生气的不是他说的话，而是他话中的意思。请再看两例：

(1) It was his nervousness in the interview ______ probably lost him the job.

A. which B. since C. that D. what

答案选C，为强调句型，被强调成分为 his nervousness in the interview，句意为很可能是面试时表现出紧张，使他失去了这份工作。

(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

答案选B，为强调句型，被强调成分为 the ability to do the job，句意为重要的是你做工作的能力，而不是你来自何地或你是从事什么工作的。

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】几个干扰项均有可能误选，主要是分不清为强调句型，或即使分清为强调句型，也分不清强调哪一个成分。

【分析】答案选A，第一空填 which，用以引导定语从句;第二空填that，为强调句的结构词，被强调部分为 in the small house (以及修饰它的定语从句 which was built with stones by his father)。此题难就难在强调句型中套用了定语从句。请再看类似例子：

(1) It was the boy _____ had been in prison _____ stole the money.

A. who, where B. that, how

C. who, that D. that, which

此题答案选C，全句为强调句，被强调成分是 the boy (以及修饰它的定语从句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

此题答案选C，全句为强调句，被强调成分是 in this room，where he was born 为修饰 the room 的定语从句。

7. Was it five oclock ______the fire broke out?

A. when B. that

C. which D. in which

【陷阱】容易误选B，误认为这是强调句。

【分析】其实，此题应选A，这不是强调句。因为在强调句中，若去掉强调句的结构词 it is [was]that，句子结构仍然完整，但此句不是这样，若去掉结构词，即为 Five oclock the fire broke out，句子不完整，但若在five oclock前加上介词at则可以，因为 at five oclock 用作时间状语。此题选A可分析为：it 表时间，when the fire broke out 为时间状语从句，全句意为火灾是5点钟发生的吗?比较下面一题(答案选B，为强调句)：

Was it at five oclock ______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】此题很容易误选A，认为这是强调句型。

【分析】其实此题应选D。做好此题的关键是正确理解上下文的语境。在此句中，it 是代词，指代 the bike，句意为：当你离开去同朋友谈话的时候，你的自行车是在这树下吗?当然，但当我回来时，自行车就不见了。现在反过来分析一下，假若选A，将此句判为强调句，句子即为 Was it under the tree that you were away talking to a friend? 若进一步转换为非强调句，句子则为 Under the tree while you were talking to a friend，句意显然很荒唐。

9. Its 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】容易误选B，认为这是强调句型。

【分析】假若选B，将此句分析为强调句，那么若将此句还原为非强调句就应该是My grandfather joined the Party and became a servant to the people more than half a century. 很显然, 句中的 more than half a century 是一段时间，然而它修饰的谓语动词 joinedbecame 却是两个终止性动词，这显然不合适。其实，此题应选C，属于It is+一段时间+since 从句句型，句意为我爷爷加入党组织成为人民的公仆已有半个多世纪了。此句的主句谓语也可以用现在完成时态(has been)，但在口语中多用一般现在时代替。

10. It was lack of money, not of effort, _____ defeated their plan.

A. which B. as

C. that D. what

【陷阱】容易误选A，受空格前逗号的影响，误认为这是一个非限制性定语从句，从而误选了A。

【分析】其实，此题最佳答案为C，整个句子为强调句，被强调成分为 lack of money, not of effort。由于句中插入 not of effort 这一结构，干扰了许多同学对 it was lack of money that defeated their plan 这一强调句的认识和理解。
