1. I forget where I read the article, or I _____ it to you now.
A. will show B. would show
C. am going to show D. am showing
【陷阱】几个干扰项均有可能误选。
【分析】正确答案选B。根据上文的语境可知句中的 or 隐含有一个虚拟的条件，即 or=if I didn’t forget where I read the article(要是我没忘记我在哪儿读过这篇文章的'话——但事实上忘了)。
2. “It looks as if he were drunk.” “So it does. _____.”
A. He’d better give up drinking
B. He shouldn’t have drunk so much
C. Health is more important than drink
D. I wonder why he is always doing so
【陷阱】几个干扰项均有可能误选，主要是受句中 drunk 一词的影响。
【分析】最佳答案为D。关键信息是It looks as if he were drunk 中的虚拟语气，句子既然用了虚拟语气，也就是说，“他喝醉了”不是事实，只是他的言行好像是醉了，所以此题的最佳答案是D。
3. “Mary looks hot and dry” “So _____ you if you had so high a fever.”
A. do B. are
C. will D. would
【陷阱】容易误选A或C。选A者，认为前后两句的动词性质应一致;选C者，认为其后带有if 条件状语从句，从语气上看，主句应用将来时态。
【分析】此题最佳答案为D。分析如下：
(1) “so + 助动词 + 主语”是一个很有用的结构，它表示“……也一样”时。如：
He likes to watch TV, and so do I. 他喜欢看电视，我也一样。
When animals and plants disappear, so will man. 当动植物消失的时候，人类也会随之消失。
(2) 由于空格后的 if 条件状语从句的谓语用的是虚拟语气(这是很重要的信息)，所以主句要用 would 而不用 will，即答案应选D。
英语语法经典例题800例：强调句（例题）
【导语】英语语法让很多学生都头疼，因为复杂难懂的句式和词组有时难以记忆。为大家整理了英语语法大全，希望对同学们的英语语法学习有所帮助。更多内容尽在。
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”。
