爱华网一、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。试比较：
1. It is strange that he didn’t come yesterday.
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 comeyesterday. 仍是一个表意完整的句子，这是一个强调句。再如：
1. It is what you do rather than what you say ____matters.（05天津）
A.thatB.whatC.whichD.this
答案A。这是一个强调主语的强调句型，去掉强调结构，剩下的是What you do rather than what you saymatters. 表意完整。
2. That was really as plan did evening. It’s years ____I enjoyedmyself somuch.
A.whenB.thatC.beforeD.since （05安徽）
答案D。由强调句型的判断方法可知，该句不是强调句型。It指时间，句意为：好几年我没有这么高兴了。since的意思是“自从那个时候起”。
二、如果强调时间、地点、原因或方式状语时，不可用when,where,why或how，而仍用that。
试比较：It was because of the accident why he was late.(误),
Itwasbecause of the accident that he was late.(正)。再如：
1. It was not until midnight they reached the camp site.（08重庆）
A. thatB.whenC.whileD. as
答案A。该题强干扰项是B，考生容易因强调时间状语untilmidnight而误选。
2. It was after he got what he had desired ____he realized it wasnot soimportant. （06辽宁）
A.thatB.whenC.sinceD. as
答案A。该句强调时间状语从句after he gotwhat he haddesired，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. thatB.howC.whichD.when
答案A。强调地点状语inNew Zealand.
三、注意强调句型的否定句和疑问句形式，在这方面很容易因弄不清句子结构而错选。如:
1. I just wonder ____that makes him so excited.（06山东）
A. why itdoes B. what hedoes C. howitis D. what itis
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 whatthat makes him soexcited,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 losther keys.
A.whenB.thatC.whereD.before （06全国卷二）
答案B。如果去掉强调结构，该句是一个“not…until”句型：Jennifer didn’t realize shehad lost her keys until she gothome. 要强调时间状语until shegothome，这时要把主句中的否定词not放在was之后。
四、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Itis…, 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 theclass.
3. It was on Sunday that he gave George thisticket.
4. It is the little girl who/ that has broken theglass.
五、在复习中有可能把It is/was…that句式都误认为是强调句型的几种情况：
1、把具有实际意义的指示代词it后面接is/was…that误认为是强调句式。
--- Where did you get to know her? （07山东）
--- It was on the farm ____ we worked.
A．thatB．thereC．whichD．where
答案D。该句易误作强调句型，所以A是强干扰项。这里wherewe worked 是定语从句，修饰the farm。It指“与她相识”这件事。欢迎转载分享，腾讯认证蔡章兵主编QQ757722345空间每天有3－5篇资源更新，欢迎点击空间顶部“关注”第一时间获得每天更新的信息。更多英语资讯，欢迎关注奇速英语微信公众号qisuen,奇速英语，助你更快成功。该题很容易受思维定势的影响而拒绝选D，因为平日教学老师一再强调，用强调句型时即使强调地点状语，也不能用where而用that。该句如果要用itwas…that强调句型的话，可改写为“It was on the farm where we workedthat I got toknow her.”
2、把it指时间、天气、距离、环境等后接be的情形误以为是强调句型。
It was twenty miles from ourcity to the village ____theaccident happened.
A.thatB.whenC.thenD.where
答案D。本题貌似Itwas…that强调句型，其实不然。句中It表示距离，where引导地点状语从句。
3、把It is/ was…that结构的主语从句误认为是强调句型。
The Foreign Minister said,“____our hope that the two sideswill work towards peace.”（04北京）
A. ThisisB. ThereisC. ThatisD. It is
答案D。如果选A和C，指示代词This和That在句中找不出指代的内容，选B意义不通。故选D。虽然选Itis后题干中出现了It is…that结构，但这不是强调句型。很明显，题干中的that从句应是主语从句，所缺的是形式主语。
4、____ is our belief that improvements in healthcare will lead to astronger, more prosperouseconomy
A. As B.ThatC.ThisD.It（06浙江）
答案D。如果去掉It is… that, 中间的ourbelief就无法处理，因此该句不是强调句型，而是一个复合句，It是形式主语，that引导真正主语。
强调句型It is/ was… that/who主要用来强调句子的主语、宾语、状语或表语。如果要强调谓语动词,应该用代动词do及其变形does或did，这三种形式常用在谓语动词之前，以加强语气。它一般只能强调现在时与过去时。如：
I do wish I could.我真希望我能。
He does look well.他的确看起来气色很好。
You did give me a fright.你真把我给吓了一跳。
