强调句
一、定义
要强调句子的某一成分，一般可用强调句型。
二：结构
It is (was) +被强调部分+that/who +句子其余部分
练习：
Li Lei’s father will work in America. —It is in America that Li Lei’s father will work.
I studied at this school a few years ago. —It was at this school that I studied a few years ago. Tom and Lucy gave us much help.
—It was Tom and Lucy that gave us much help. 2. 强调句句型转换----一般疑问句
Tommy answered the telephone. It is Tommy who answered the telephone? -- Is it Tommy who answered the telephone? 总结强调句一般疑问句的结构：
“Is / Was it+ 被强调部分 + that / who+句子其他部分…”。
3. 强调句特殊疑问句：
He got married in 1995. It was in 1995 that he got married. Was it in 1995 that he got married? When was it that he got married?
总结强调句的特殊疑句：
特殊疑问词+is / was it that+句子其余部分…
4． 对not…until时间状语从句进行强调时，其句型是：
It is / was not until… that-从句， 即not和until在强调句中总是紧挨着的。例如：
It was not ____ she took off her dark glasses ____ I realized she was a famous film star. A. when; that B. until; that C. until; when D. when; then 强调句型注意事项：
注意：
1、 比较：
It is strange that he didn’t come yesterday.
It is you and Tom that didn’t come yesterday.
3、强调句型的否定句和疑问句形式，如: 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? 1. I just wonder ____that makes him so excited.
A. why it does B. what he does C. how it is D. what it is 答案D。正常语序的强调句型容易看出，但要注意它的变体。如果把该题变换一下语序：it is what that makes him so excited,不难看出这是强调句型的特殊疑问句形式，强调了疑问代词what，因为wonder后宾语从句，故用了陈述语序。
2. It was not until she got home ____Jennifer realized she had lost her keys. A. when B. that C. where D. before
答案B。如果去掉强调结构，该句是一个“not… until”句型：Jennifer didn’t realize she had lost her keys until she got home. 要强调时间状语until she got home，这时要把主句中的否定词not放在
