强调句的基本结构是It+be+被强调成分+that (who)…，其中的结构词it 和that (who)为高考英语考查强调句时最常考查的考点。如：
1. I don’t mind her criticizing me， but _________ is how she does it that I object to.
A. it B. that C. this D. which
【解析】答案选A。此题考查it is ...that…这一强调句句型。句意为：我不介意她批评 我，我反对的是她批评我的方式。句中空格处填强调句结构词it。
2. It is not who is right but what is right _________ is of importance.
A. which B. it C. that D. this
【解析】答案选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。句中空格处填强调句 结构词that。
Jim told us the news.(非强调句)
It was Jim that told us the news.(强调句型的陈述句形式)
Was it Jim that told us the news？(强调句型的一般疑问句形式)
Who was it that told us the news？(强调句型的特殊疑问句形式)
特殊疑问句形式的强调句可视为对陈述句强调中的被强调成分提问得来，如对It was yesterday that he arrived. 这一句中的yesterday提问，即得到When was it that he arrived？
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
【解析】答案选D。注意what it is that makes him so excited为宾语从句，用作动词wonder 的.宾语。如果去掉主句I just wonder将原句改为疑问句则是：What is it that makes him so excited？
2.— _________ that he manage to get the information？
—Oh， a friend of his helped him.
A. Where was it B. What was it C. How was it D. Why was it
not...until用于强调句型时的基本形式为It is (was) not until…that…。如：
1. It _________ we had stayed together for a couple of weeks _________ I found we had a lot in common.
A. was until； when B. was until； that
C. wasn’t until； when D. wasn’t until； that
【解析】答案选D。此题考查not…until…句式的强调形式。又如：It was not until she took off her dark glasses that I realized she was a famous film star. 直到她取下墨 镜，我才意识到她是一位著名影星。
2. It was not until she got home _________ Jennifer realized she had lost her keys.
A. when B. that C. where D. before
【解析】答案选B。考查not…until…句式的强调形式。又如：It was not until I met you that I knew real happiness. 直到我遇到你以后，我才真正体会到幸福。
1. It will soon be five years _________ we came to live in Cairo.
A. that B. when C. since D. as
【解析】答案选C。此题不是考查强调句型，而是考查since的用法，句意为我们来到开 罗居住快五年了。又如：It is two years since he left the country. 他离开这个国家已经两 年了。/ It’s quite some time since we wrote to each other. 我们互相通信已有不少时间了 。
2. Was it here _________ you were away talking to a friend？ Sure. But when I got back there， it was gone.
