大学英语复杂结构的强调句式
导语：强调句是一种修辞，是人们为了表达自己的意愿或情感而使用的一种形式，下面YJBYS小编解析复杂的强调句，欢迎参考!
一、结构分析
强调结构中的it is (was)…that (who)…为使一个非强调句变成强调句的结构词，在通常情况下，去掉它，句子依然是成立的——这是判断一个句子是否为强调结构的重要标志。如下面这个句子是强调句，因为去掉it was…that…后句子依然成立，且意思一致：
It was my mother who finally called the police. 最终报警的是我母亲。
→My mother finally called the police. 最终报警的是我母亲。
请看下面一句，空白处是填that还是其他的什么词?
It was ten o'clock _______ he returned home.
此处不能填that，因为若填that把它视为强调句，那么就可以去掉it was…that…而使句子结构完整，意思不变，事实上并非如此，因为我们是不能说Ten o'clock he returned home的，除非改为At ten o'clock he returned home才是正确的。
比较下面两句(第1句不是强调句，但第2句是强调句)：
It was ten o'clock when he returned home. 他回家的时候已是10点钟了。
It was at ten o'clock that he returned home. 他是10点钟回家的。
二、时态一致问题
一般说来，强调结构it be…that…中的be的时态应与句子时态一致，即同时用现在时，或同时用过去时，有时也可能用将来时。如：
It is not I who am angry. 发怒的不是我。(同时用现在时)
It was my two sisters who knew her best. 是我的两个姐妹最了解她。(同时用过去时)
It will not be you who will have to take the blame for this. 对此须受责难的将不是你。(同时用将来时)
但有时也可以不一致，这主要见于强调结构用it is…that…(即用的是现在时)，而句子用的是过去时。如：
It is Miss Williams who enjoyed reading novels as a pastime. 是威廉姆斯小姐以读小说来消遣。
句子结构比较复杂时，尤其是当被强调成分比较复杂时，有的同学们就不能识别句子所用的强调结构，从而不能正确作出选择。如：
It was lack of money, not of effort, that defeated their plan. 他们的`计划受挫，原因是缺少钱而不是没有尽力。
It was more in sorrow than in anger that he criticized his former colleague. 他批评以前的同事，并非出于气愤而是为他惋惜。
It is the protection for the trees that really matters, rather than how many trees are planted. 真正重要的在于对树木的保护，而不在于种了多少树。
As far as he's concerned, it's not doing something wrong that matters, but not being caught doing something wrong, 就他而论，重要的不是做错事，而是做错事不被抓住。
请看两道题：
(1) It is not who is right but what is right _______ is of importance.
A. which B. it C. that D. this
答案为C。此题考查it is…that…这一强调句式，被强调的是not who is right but what is right，全句意为：重要的不是谁是对的，而是什么才是对的。
有时考查not…but…的同义结构…rather than…与强调结构的综合运用。如：
(2) It is what you do rather than what you say _______matters
A. that B. what C. which D. this
答案为A。被强调成分为what you do rather than what you say，全句意为：重要的是看你怎么做，而不是看你怎么说。
