　　③(2014·四川高考改编)Was it because Jack came late for school that Mr. Smith got angry?

　　二、强调句的特殊用法

　　强调句与其他句型的结合，注意以下几种用法：

　　1．强调句型与名词性从句的结合

　　句式特征为： 整个强调句型用作名词性从句或者在强调句型中含有名词性从句时，从句要用陈述语序。

　　Do you know what it is that they will do next?

　　你知道他们下一步究竟要做什么吗？

　　2．强调句型与定语从句的结合

　　句式特征为： 在强调句型的被强调部分或其他部分中找出一个先行词，附上修饰该部分的定语从句，这样整个句子结构就变得非常复杂。应特别注意不要混淆定语从句的关系词和强调句型中的that/who部分。

　　It was last Spring when they worked together(when引导的定语从句) thatthey began to become good friends.

　　是在一起工作的去年的春天里他们开始成为了好朋友。

　　It was in the school where they had their schooling (where引导的定语从句) thatthey had a get­together again twenty years later.

　　二十年后，他们是在曾接受教育的学校里又聚在了一起。

　　3．强调句型与not ... until句型的结合

　　"It is/was not until＋被强调部分＋that＋其他剩余部分．"

　　It was not until he came backthat I knew the result.

　　直到他回来，我才知道结果。
