高考英语语法之：强调句型
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 bought 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。
I t 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that(尤其是当这些状语为介词短语时)。
