强调句型复习指导

一、强调句的基本结构及用法

1. 基本结构。如：It+be+被强调成分+that (who)…

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】在该强调结构中，it is (was)…that (who)…为结构词，它通常可以省略，而不影响句子的意思。

2. 关于that与who。当被强调部分指人时，可以用who代that；当被强调部分指物时通常用that。注意：强调事物时，通常不宜用which来代that，另外当强调时间或地点状语时，通常也不能用when / where代that(尤其是当这些状语为介词短语时)。

3. 关于被强调成分。该强调句型中，被强调的成分除了是名词、代词、介词短语等之外, 也可以是从句。如：

It is when he got back that he knew what had happened. 他回来后才知道所发生的情况。

It was because he loved my money that he married me. 他是因为爱我的钱才同我结了婚。

【注】(1) 该句型可强调because引导原因状语从句，但通常不能强调由 since, as引导的原因状语从句，另外也不强调由although引导的让步状语从句。

(2) 该句型可以强调主语，但不强调表语。

二、两种值得注意的强调句结构

1. 强调句的特殊疑问句形式。强调句型的陈述句形式和一般疑问句形式一般还好理解，但若以特殊疑问句形式出现，则很容易误解。比较：

Jim told us the news.(非强调句)

It was Jim that told us the news.(强调句型的陈述句形式)

Was it Jim that told us the news.(强调句型的一般疑问句形式)

Who was it that told us the news.(强调句型的特殊疑问句形式)

特殊疑问句形式的强调句可视为对陈述句强调中的被强调成分提问得来，如对It was yesterday that he arrived. 这一句中的yesterday提问，即得到When was it that he arrived?

2. not...until用于强调句。其基本形式为It is (was) not until…that…。比较：

He didn’t come until his wife left. 他妻子走了之后他才来。

It was not until his wife left that he came. 他妻子走了之后他才来。

They didn’t start until the rain stopped. 直到雨停他们才出发。

It was not until the rain stopped that they started. 直到雨停他们才出发。
