强调句型1. 用It is／was…that／who…句型表示强调。
被强调的部分（通常是句子的主语、状语、宾语或宾语补足语）放在is／was的后面，如被强调的是人，则后面可用who，whom等代替。
He met an old friend in the park yesterday.强调主语：强调宾语：强调时间状语：强调地点状语：（二）not … until …句型的强调句1、句型为：It is/ was not until + 被强调部分+ that + 其它部分e.g. 一般句：He didn’t go to bed until/ till his wife came back.强调句：It was not until his wife came back that he went to bed.2、留意：此句型只用until，不用till。

完整版)高中英语强调句型专题讲解
完整版)高中英语强调句型专题讲解强调句的基本结构及用法强调句是用来强调说话人想要强调的语言信息，以给对方留下强烈印象和感受的句子。
在汉语中，通常会加上“正是”等字眼。
其基本结构为：It + be的适当形式+被强调成分+ that (who) +其他成分。
例如，原句“他昨天在这家店买了这本书。
”可以改写成强调句：It was he that bought the book in this ___.（强调主语he）It was the book that ___.（强调宾语the book）It was in this shop that he bought the book yesterday.（强调地点状语in this shop）需要注意以下几点：在强调结构中，It没有任何意义，不能替换成this或that 等。
It is (was)…that (who)…是结构性词语，不能省略。
如果省略，剩下的部分在语法结构和句子含义上都是完整的，这正是它与定语从句等的本质区别。
当被强调部分指人时，可以用who（被强调部分的人作主语或宾语时）或者whom（被强调部分的人作宾语时）代替that；当被强调部分指物时通常用that；当被强调部分既包括人又包括物时，用that不用who。
当被强调部分是代词时，用who不用that。
当强调时间或地点或原因状语时，不能用when / where/why代替that（尤其是当这些状语为介词短语时）。
例如，下面两个句子中的强调句都是正确的：It was only when I ___.（强调时间状语when）It was in Qingdao that I saw the sea for the first time.（强调地点状语in Qingdao）About 600 years ago。
the first clock with a face and an hour hand was invented。

高中英语高考复习基础语法强调句知识讲解
高中英语强调句为了强调､突出某种意思,为了强调句子的某一部分,会用到强调结构｡笼统的说,强调结构可以分为口语和书面语两种强调结构｡一､口语的强调口语中强调比较简单,主要是通过重读来实现的｡如下句:Tom never goes to the cinema.1) 要强调Tom而不是别人从不去影院,会重读TOM,从而形成'TOM never goes to the cinema.2) 要强调Tom从不去影院,而不是去其他地方,会重读the CINEMA,从而形成Tom never goes to the 'CINEMA.1) 而要强调Tom从不NEVER去影院,会重读NEVER,从而形成TOM 'NEVER goes to the cinema.相对要简单很多｡二､书面语的强调一般我们所说的强调,指的是书面语的强调｡常用的就是强调句､倒装等一些特殊句式｡（一）强调句句型的种类及句型⒈ 陈述句的强调句型: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｡如:It was yesterday that he met Li Ping.⒉ 一般疑问句的强调句型:同上,只是把is/ was提到it前面｡如:Was it yesterday that he met Li Ping?⒊ 特殊疑问句的强调句型:被强调部分(通常是疑问代词或疑问副词)+ is/ was + it + that/ who + 其他部分?如:When and where was it that you were born?⒋ 强调句例句:针对I met Li Ming at the railway station yesterday.句子进行强调｡① 强调主语:It was I that (who) met Li Ming at the railway station yesterday.② 强调宾语:It was Li Ming that I met at the railway station yesterday.③ 强调地点状语:It was at the railway station that I met Li Ming yesterday.④ 强调时间状语:It was yesterday that I met Li Ming at the railway station.⑤注意:构成强调句的it本身没有词义;强调句中的连接词一般只用that､who,即使在强调时间状语和地点状语时也如此,that, who不可省略;强调句中的时态只用两种,一般现在时和一般过去时｡原句谓语动词是一般过去时､过去完成时和过去进行时,用It was…,其余的时态用It is…（二）not … until … 句型的强调句⒈ 句型为:It is/ was not until + 被强调部分 + that + 其他部分如:普通句:He didn't go to bed until/ till his wife came back.如:强调句:It was not until his wife came back that he went to bed.⒉ 注意:此句型只用until,不用till｡但如果不是强调句型,till, until可通用;因为句型中It is/ was not …… 已经是否定句了,that后面的从句要用肯定句,切勿再用否定句了｡（三）谓语动词的强调⒈ It is/ was …… that …… 结构不能强调谓语,如果需要强调谓语时,用助动词do/ does 或did.如:Do sit down. 务必请坐｡He did write to you last week. 上周他确实给你写了信｡Do be careful when you cross the street. 过马路时,务必(千万)要小心啊!⒉ 注意:此种强调只用do/ does和did,没有别的形式;过去时用did,后面的谓语动词用原形。
