这样子说吧，（it is that） 你的原句 当强调对象是人的时候可以把 that 改成 who接着把你原句中要强调的部分（时间状语，地点状语，主语，宾语====）挪到it is 后面就成了强调句啦
拿一杯铁
强调句型：It is/was +… who/that…；被强调部分如果为主格人称代词，who/that后的动词和主格人称代词在人称和数上保持一致。
1. 如强调句型指现在或未来的情况用It is指过去用It was。
e.g. It is I who/ that am wrong.
分析：被强调部分为人强调词可用who也可用that. 指现在的情况所以以 It is开头，被强调部分是 I谓语用 “am”
原句： I am wrong.
e.g. It was him who\that I saw the day before yesterday.
原句为 I saw him the day before yesterday.
分析：指过去的情况用It was 开头，被强调部分为人所以强调词仍是who\that.
2. 被强调部分往往为句子的主语、宾语、时间状语、地点状语等，但有时也可以强调比较复杂的内容。 如时间状语从句、地点状语从句、not until… 结构、not only…but also…和as well as…等结构。
e.g. It was only when I reread his poems recently that I began to appreciate their beauty. (appreciate means understand and enjoy the good qualities or value of something欣赏、鉴赏、领会)
分析：强调部分为复杂的时间状语从句强调词不能使用when只可用that
e.g.It is not only he but also his parents who\that have been to Beijing.
3. 被强调部分为人称代词时，原句用什么格强调句也用什么格。
It强调句型最基本的句式结构为：
It be＋被强调部分＋that/who＋句子。被强调部分是除谓语之外的其他句子成分，可以是单词、短语，也可以是从句；当强调人时，可以用who 或that；强调其他成分，则只能用that。对not……until……结构的强调句型为：It is/ was not until+被强调部分+that+其他部分。

It is/was + 强调的部分 + that/who + 句子剩下部分（语序不要变，只要把强调部分放到强调的部分的位置即可）集注这个句型不能强调谓语，其他成分都可以，（可以是一个名词、人），一般强调的是状语。如果前面是is，那么that/who 后面接的句子的谓语时态就是现在时如果前面是was，那么that/who 后面接的句子的谓语时态就是过去时强调的部分是人who和that都可以用，一般用who ，强调其他的只能用that 。集注只能是who或that ，绝对不会有其他什么when啊what啊例：It is I who/that am right. It was in the park that Tom lost his watch. Is it Professor Wang who teaches you English? （疑问句只要把is/was 提前） Was it during the Anti-Japanese War that he died? It is there that accidents ofen happen. It is love that makes the world turn around.最快判断是否是强调句的方法：把 It is/was that/who 去掉，剩下的部分是完整的句子则是强调句。如上面第1句去掉后，再调整语序就是Tom lost his watch in the park。该句强调的是在公园丢的。而不是在别的地方。常见的强调句还有这两种：It is + 时间 + since + 句子It was + 时间(not long/ two years等)+ before + 句子
