强调”就是使句子的某一部分比一般情况下显得更加重要。英语表达中，要强调句子的某一成分，一般可用强调句型“It is (was) +that (who) +句子的其余部分”。It在句中无意义，只起引出被强调部分的作用。被强调的部分指人时，除可用that外，还可换用who(强调宾语指人时也可用whom)。
强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其他部分。
e.g. It was Li Ming who locked the class door last night.
e.g. It was a deer that I saw in the park yesterday.
e.g. It was yesterday that he met Li Ping.
It was in New Zea land that Mike first met Mr. Smith.
强调主语时，that或who后面的谓语动词的形式仍然取决于原句中的主语;be的变化只有is和was两种形式，如果要表示现在时将来时的其它各种形式时，就用It is…, 表达过去时的各种形式时，用It was….一般要与谓语动词的时态一致。如:
1.It is I who/ that am an English teacher.
2.It is the boy who/ that speaks English best in the class.
3.It was on Sunday that he gave George this ticket.
4.It is the little girl who/ that has broken the glass.
试比较:It was because of the accident why he was late. (误)
It was because of the accident that he was late. (正)
1.It was not until midnight they reached the camp site. (08重庆)
A. that B.when C.while D. As
2. It was after he got what he had desired ____he realized it was not so important.
A.that B.when C.since D. As
答案A。该句强调时间状语从句after he got what he had desired，题干意思是“得到他所梦寐以求的东西后他才意识到一切都不那么重要”。不要误选B。
3.It was in New Zea land ___ Elizabethfirst met Mr. Smith. (08全国II)
A. that B.how C.which D.when
去掉强调结构It is (was) … that(who)…后，剩下的词仍能组成一个完整的句子。这是判断是不是强调句型的关键。
句1. It is strange that he didn’t come yesterday.
句2. It is you and Tom that didn’t come yesterday.
显然：句1去掉It is…that …后，句子结构不完整，是主语从句;
句2去掉It is… that …后，句子变为 you and Tom didn’t come yesterday. 仍是一个表意完整的句子，这是一个强调句。
