1. “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)。

　　2. “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。

　　3. 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”。

　　4. 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：
