英语强调句一、强调句的基本结构及用法强调句常用来突出说话人要强调的语言信息，给对方以强烈的印象和感受。

译成汉语时，常加上“正是…”等字眼。

其基本结构是：It+ be的适当形式+被强调成分+that (who)+其他成分He bought the book in this shop yesterday.→It was he that bought the book in this shop yesterday. (强调主语he)→It was the book that he boug ht in this shop yesterday. (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)【注意】1.在该强调结构中，It 无任何意义但不可以换成this或者that等。

It is (was)…that (who)…为结构词，假如去掉，剩下部分在语法结构和句子含义上均完整，这一点正是它和定语从句等的本质区别。

2. 关于that与who：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，用that不用whoIt was the things and people that they remembered that they were talking about．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that(尤其是当这些状语为介词短语时)。

It was from him，his chemistry teacher，that Paul learned to watch carefully in class．3.关于be的适当形式：在强调结构中，无论被强调的是人还是物，单数还是复数，be动词一律用单数is/was形式。

①如果原句的谓语动词时态是现在范畴(一般现在时、现在进行时、现在完成/现在完成进行时、一般将来时、将来进行时、将来完成时等)，就用is。

在强调句型中，能够被强调的句子成分通常为主语或宾语（名词、代词）、状语（介词短语、时间或地点状语从句或者because 引导原因状语从句）等，但不能强调谓语动词、表语或补语（形容词或名词充当）、although引导的让步状语从句、for、since, as引导的原因状语从句、if条件状语等。
