4. 强调句型与时间状语从句的辨析

当用强调句型强调时间状语时，去掉“it is/was”和连词“that”原句仍然成立。而在时间状语从句中，若去掉“it is/was”和连词“when/before”，原句不能成立。

It was at 14:28 that the terrible earthquake broke out. (强调句型)

It was 14:28 when the terrible earthquake broke out. (状语从句)

3. 强调句型结构与定语从句的混合使用

在高考试题中，为了增加试题的难度，命题人将强调句型与定语从句混合起来，使句子结构更加复杂。我们要注意从语法角度来分析句子，理清结构强调句型语定语从句。例如：

It was on the farm where we worked that I got to know her。
