一、重点突出的强调句型
强调句型可强调除谓语动词和表语外的其他任何成分，如主语、宾语、状语等。强调句型的灵活运用不仅有助于增强表达效果，突出要强调的重点，更能彰显考生对英语表达的把握能力。其基本结构为：It is/was＋被强调部分＋that/who＋其他。

1.强调句型的写法
在写作时，可以使用强调句型来提升句子的层次，写作时可采用“四步法”。
第一步：写出一个句子
I picked up an old bag on the playground last Sunday.
第二步：找出要强调的句子成分
假如要强调地点状语on the playground。
第三步：确定强调句型的时态是is还是was
原句用了一般过去时，所以此处的强调句型也用一般过去时，即it was...
第四步：套用强调句型：It is/was＋被强调部分＋that＋其他。
It was on the playground that I picked up an old bag last Sunday.
2.强调句型的其他形式
(1)Is/Was it＋被强调部分＋that＋其他？
Was it on that farm that his father spent his childhood?
是在那个农场里他的父亲度过了童年吗？
(2)特殊疑问词＋is/was it＋that＋其他？
What was it that made the girl so sad that day?
是什么使那个女孩那天那么难过？
(3)It is/was not until...that...
It was not until he failed the exam that he realized that he was wrong.
直到他考试不及格，他才意识到自己错了。
