一、强调句句型
1. 陈述句的强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其他部分。
e.g. It was yesterday that he met Li Ping.
2. 一般疑问句的强调句型：同上，只是把is/ was提到it前面。
e.g. Was it yesterday that he met Li Ping?
3. 特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其他部分？
e.g. When and where was it that you were born?
4. 强调句例句：针对I met Li Ming at the railway station yesterday.句子进行强调。
强调主语：It was I that (who) met Li Ming at the railway station yesterday.
强调宾语：It was Li Ming that I met at the railway station yesterday.
强调地点状语：It was at the railway station that I met Li Ming yesterday.
强调时间状语：It was yesterday that I met Li Ming at the railway station.
5. 注意：构成强调句的it本身没有词义；强调句中的连接词一般只用that, who，即使在强调时间状语和地点状语时也如此，that, who不可省略；强调句中的时态只用两种，一般现在时和一般过去时。原句谓语动词是一般过去时、过去完成时和过去进行时，用It was ... ，其余的时态用It is ... 。
二、not … until … 句型的强调句
1. 句型为：It is/ was not until + 被强调部分 + that + 其他部分
e.g. 普通句：He didn't go to bed until/ till his wife came back.
强调句：It was not until his wife came back that he went to bed.
2. 注意：此句型只用until，不用till。但如果不是强调句型，till, until可通用；因为句型中It is/ was not ... 已经是否定句了，that后面的从句要用肯定句，切勿再用否定句了。
三、谓语动词的强调
1. It is/ was ... that ... 结构不能强调谓语，如果需要强调谓语时，用助动词do/ does或did。
e.g. Do sit down. 务必请坐。
He did write to you last week. 上周他确实给你写了信。
Do be careful when you cross the street. 过马路时，务必（千万）要小心啊！
2. 注意：此种强调只用do/ does和did，没有别的形式；过去时用did，后面的谓语动词用原形。
1. 陈述句的强调句型：It is/ was + 被强调部分（通常是主语、宾语或状语）+ that/ who（当强调主语且主语指人）+ 其他部分。
e.g. It was yesterday that he met Li Ping.
2. 一般疑问句的强调句型：同上，只是把is/ was提到it前面。
e.g. Was it yesterday that he met Li Ping?
3. 特殊疑问句的强调句型：被强调部分（通常是疑问代词或疑问副词）+ is/ was + it + that/ who + 其他部分？

很好理解。句子中主语为“人”时，可以用“who”来做代词，和文言文中“其”是一个意思。
打个比方：Mike is an arrogant man, who always looks down at others (mike是一个高傲的人，（他）一直从高处看别人）
而句子主语为非人类时（无论动物还是非生物都一样）用“that”做代词。
This is one of the best chairs, that this furniture store sells (这是一款这家商店售卖的最好的椅子）追问

哦哦谢谢能不能顺便问一道题
多年颈椎病算是治好了= =
进行强调是否是指拓展句子？
如果要拓展的话，可以这么写：He told the truth to us, that it was him who did it
这句话中“that”并非代词而是强调了
