强调句型的构成是：It is (was) + 被强调部分+ that (who) + 句子的其他成分。被强调的部分放在 It is (was) 之后，其它部分置于that之后。被强调部分可以是主语，宾语，表语或状语。强调的主语如果是人，可以由who代替that。
1. 被强调的成分举例：
原句：Tom found my pen in the classroom yesterday.
强调主语：It was Tom who / that found my pen in the classroom yesterday.
强调宾语：It was my pen that Tom found in the classroom yesterday.
强调地点状语：It was in the classroom that Tom found my pen yesterday.
强调时间状语：It was yesterday that Tom found my pen in the classroom.
2. 强调句型的一般疑问式：
直接把is或was提到it之前即可。例如：
Was it Tom that found your pen in the classroom yesterday?
3. 强调句型的特殊疑问式：
特殊疑问词+ is (was) it + that +句子的其他成分。特殊疑问词即是被强调的成分。例如：
Who was it that found your pen in the classroom yesterday?
4. that (who) 有时可以省略：
这种强调句型中的that或who有时可以省略。例如：
It was my brother (that / whom) you saw the other day.
5. 强调原因状语从句要注意：
若从句由as或since引导，强调时则改为because，这是因为，because引导的原因从句表示的意义非常强烈，符合强调句的目的。例如：
As she got up late, she missed the first bus. 变为：
It was because she got up late that she missed the bus.
6. 强调句的否定转移：
有些否定句在变成强调句时，要把否定转移到被强调的词语之前。尤其是“not... until...”句式的强调要特别注意。例如：
He didn't realize his mistake until the teacher had told him. 变为：
It wasn't until the teacher had told him that he realized his mistake.
【注意】 在强调句式中，虽然not被提前，但“not... until...”句型不要倒装。
高考中强调句型考查热点
考点一：强调句型的基本结构
强调句型“It is / was + 被强调的成份 + that + 其他成份”用来强调主语、宾语和状语等成份。that只起连接作用，不作成份，但不能省略。有时强调的部分比较特殊，如主语从句、状语从句、名词、不定式短语、V-ing的复合结构等。如：
It was in the library that I saw her yesterday. 我昨天正是在图书馆见到她的。
考点二：特殊句式中的强调句型
1. 如果强调的是特殊疑问句中的疑问词，表示“到底”、“究竟”等语气时，就用如下结构：
“特殊疑问词 + is / was + it + that + 该句的其余部分”。如：
How is it that you usually go to work? 你通常是怎样去上班的？
2. 在强调“not... until”结构中由until所引导的短语（或从句）作时间状语时，要用固定的强调句型：“It + is / was + not until... + that + 该句的其余部分”，that所引导的从句中的谓语动词用肯定式。如：
His father didn't come back from work until 12
o'clock. = It was not until 12 o'clock that his father came home form work. 直到12点他的爸爸才下班回家。
考点三：强调句型与时间状语从句、定语从句的判断
强调句型要注意和it代表时间、距离、温度、自然现象、具体事物或人物等时所构成的各种句型的区别。试比较：
It was on March 1 that I had my hair cut. (强调句)
It was March 1 when I had my hair cut. (后面是定语从句)
判断是否是强调句，可采用“还原法”。如果还原为一般句式后，句子各种成份完整，则是强调句。否则不是。如第一句可还原成：I had my hair cut on March 1.
考点四：偶尔考查谓语动词的强调句式
英语中常用助动词do、does或did强调谓语。如：
He did go to the airport yesterday, but he didn't find you. 他昨天确实去了机场，但他没有找到你。
1." I watch him play basketball."整个句子结构为S+V+O+O.c. "play"在句中做宾语补足语（Object complement），补充说明宾语的动作或状态。其实，paly和playing都可以，如果没有具体语境的话。只是，用"play"时，主语看到的是宾语动作的整个过程。而用，"playing"时,更侧重于看到宾语所发出的动作正在进行。这里是“我看到他打篮球的整个过程”，所以用"play"。
2." take care of "这类v+n+prep结构在有的语法书中被称为词组动词，意思是“照顾，照看”。在这里，做个简单的句型转换，整个题目，应该就明白了。
You must take good care of your little sister for she is too young to look after herself.(主动语态）
Your little sister must be taken good care of for she is too young to look after herself.(被动语态）
Good care must be taken of your little sister for she is too young to look after herself.(被动语态）
通过以上转换，不难看出，类似的句子由主动语态转换为被动语态时，有两种转换方法。以上三句，第一句可能为讲述事实；第二句，更侧重于说动作的承受者，即“你的妹妹而不是别人必须好好被照顾”；第三句，也就是你问题中的那句，更加强调，“精心的照顾必须给你的妹妹”。所以说，这里的"Good care"被提前，是强调，是说话人为了引起听话人的注意，特别嘱托。
2)the facts and the order of the facts is enough.
3)But if the open air and adventure mean everything to Defoe, then they mean nothing to Jane Austen.
4)we turn to Hardy, and we are once more spun around.
前面一塌糊涂，没有改的价值，根本不知道在说什么。从yet之后没有错误而且很有文采。

问题深刻。有两点：1. they thought是插入语，去掉不影响句子结构正确。2. whichever way 与whoever, whatever (+名词） 一样，可以引导【名词性】从句，=（任一）名词+that-定语从句。我觉得这个句子应该是 in whichever way(that) they thought would be most attractive to audiences。这是一个常见...
