结论
强调句型的特点: 用来强调一个句子中除谓语 以外的句子成分。去掉强调句式 It is/was…that…后，剩余句子的 结构和句意是完整的。
强调句的一般疑问句和特殊问句
一般疑问句形式是：Is/Was it + 被强调部分+that+ 句子的其他部分？ It was this car that you bought in that shop last month. → Was it this car that you bought in that shop last month? 特殊问句形式是：Wh-疑问词 + is/was it+that+句子 的其他部分？如： It was last month that you bought this car in that shop . → When was it that you bought this car in that shop?

It’s (high/about) time (that) sb. did sth.
time “时候,时间”其后的that从句常用一般过去时或 者should +动词原形（ should不能省） It is high time that we went to school.

从句的强调： （1）I came home late because it was raining hard. It was because it was raining hard that I came home late.(强调原因状语从句) (2) What you said really made us sad.

如果去掉it is／ was ... that句子仍然通顺成立，则为强 调句型，不成立不通顺，则为定语从句。如果句子通顺， 意思完整，那么，这就是一个强调句型。
