爱华网强调句的结构
常考的强调句结构是： It is (was) 被强调部分+ that (who) + 句子其它部分。 此结构强调的成分仅限于主语，宾语和状语。 It is from the sun that we get light and heat. It was not until I had read your letter that I understood the true state of affairs.
原句为陈述句： Mary did the experiment in the lab yesterday evening.
强调主语： It was Mary who did the experiment in the lab yesterday evening.
强调宾语： It was the experiment that Mary did in the lab yesterday evening.
强调时间： It was yesterday evening that Mary did the experiment in the lab. (注意不用when)
强调地点： It was in the lab that Mary did the experiment yesterday evening. (注意不用where)
原句为特殊问句:
How did he come here?
强调how: How was it that he came here?
Why did he came late?
强调Why: Why was it that he came late?
原句为not... until 结构
He didn't come until 7 o'clock.
强调not... until : It was not until 7 o'clock that he came.
强调句的时态: 如果被强调句为过去时则强调句用It was ... that.
1）典型例题 It was last night ___ I saw the car. A. where B. when C. that D. which 答案C. 强调句的结构是： It +be +强调部分 + that (who) + 主谓句。 强调句的连词只有两个，that和who。当强调的部分是人，且为句子的主语时，才用 "who"，其余用that。
2）易错试题 It is ten years ___ Miss Green returned to Canada. A. that B. when C. since D. as 答案C. 考点是连词用法。 本题易误选为A. that. 其实本句不是强调句。若是，去掉It be… that还应是一个完整的句子。而本句去掉 'It is…that'，只剩下ten years Miss Green returned to Canada. 不成句。因此本句不是强调句。 It is /was +时间+ since… 其中is等于 has been; was 相当于 had been.

从高考试题看强调句型的用法
山东阳谷二中 玄志斌丁玉荣
英语中“Itis/was+被强调部分+who/that+其它”是强调句型的基本构成。这种结构在中学英语课本中频频出现，引起高考命题者的格外关注。下面让我们看一下与强调句型有关的高考试题：
1．It is not who is right but what is right___is ofimportance.(2007高考 重庆27)
A. which B. it C.that D. this
解析：选C。考查强调句型，that是强调句型的结构词，句意是“重要的不是谁正确，而是什么是正确的。”
2．It __we had stayed together for a couple of weeks___I found wehad a lot in common.（2007高考浙江10）
A. was until; when B. was until;that C. wasn’t until; when D.wasn’t until; that
解析：选D本题考查not…until结构的强调句式。在not…until结构中，如果对until及其后面的部分进行强调，要将not一词提前，形成“Itis/was not until…that…”的结构注意尽管强调的是时间，但不可以用when。
为了帮同学们更好地掌握强调句型的用法，笔者依托高考经典试题，对这一句型进行分析和归纳，供同学们参考。
强调句的基本句型是：“Itis/was+被强调部分+that/who从句。”被强调部分可以是主语、宾语和状语等，使用时应注意以下几点：
⑴不论强调的是哪一部分，后面都用that，指人时可用who.
It is I that/who am going to the park this Sunday.
说明：当被强调的是主语时，代词要用主格形式。如：
It was I that put forward the question.
⑵被强调的是时间、地点、原因或方式等状语或状语从句时，不能用when, where,how，用that.
It was in the park that I met her yesterday.
It was yesterday that I met her in the park .
例：（1）.It was there, the police believe,___she was able toactivate the recorder she kept in her bag .
A.until B. which C.that D. when
解析：选C 被强调部分为地点状语there，the police believe为插入语
（2）It was after he got what he had desired___he realized it wasnot so important.(2006辽宁 35)
A.that B. when C.since D. as
解析：选A 被强调的是时间状语after he got what he haddesired
⑶原句的谓语动词如果是现在或将来时态用Itis…that/who…，如果原句的谓语动词是过去时态，则用Itwas…that/who…。
It is he that reads the book .
It was he that read the book .
⑷对not…until时间状语从句进行强调时，用It is/wasnotuntil…that从句，也就是说not和until在强调句中不可分离。
It was not until he came back that I went to bed.
例:（1） It was not until she got home ___Jennifer realised she hadlost her keys.（2006全国卷II 9）
A.whenB.thatC.where D.before 、
解析：选B 考查强调句中对not until的强调，是否能辨析出引导词that.
（2）.___the catastrophe happened that the local governmentrealized the importance of substantial development .(2007江苏常州)
A.It was until B. Not until C.Until D.It was not until
解析：选D 考查强调句中not until的用法.考查了 It was not until the catastrophehappened that .
⑸强调句的疑问形式：
Was it in the street that I met him yesterday?
When was it that he made up his mind to study English?
例：(1) Was it form the lake___he often went fishing___he savedthe drowning girl?（2007山东潍坊二模）
A. that; that B. where;where C. where;that D. that;where
解析：选C 解答此题关键是能够对句型进行正确的分析和判断。本题题干为一个强调句式，it was+被强调部分+that/who，lake后面是个定语从句，由关系副词where引导，第二空才是强调句中的that。
(2) I really don’t know ___ I had my moneystolen.（2006山东烟台3月）
A. when was it that B. that it waswhen C. where it was that D. itwas where that
解析：选C强调句作know的宾语，语序应为陈述句语序，被强调部分为where，但是强调句为宾语从句时，这类wh-连接代词或副词常置于it之前，作宾语从句的连接词。
⑹强调句型与定语从句及其他句式的区别。
即去掉强调句式结构或经过语序相应调态后，原句仍成立。
It was because he was ill that he didn’t go to school.
= He didn’t go to school because he was ill.
It was at midnight that I got back home yesterday.
It was midnight when I got here yesterday.
It was two years ago that I joined the army.
It is two years since I joined the army.
