Professer Lee's book will show you_can be used in other fields.
A that you have observed
B that how you have observed
C how that you have observed
D how what you have observed
请详细解答！谢谢！

Answer 1

选A 你记住两点，第一点，how where which 什么的不能引导名次性质从句（宾语从句什么的）
只能用what 和 that。 第二，只有that 后面可以加how where which 什么的，因为that 放在从句开头引导从句的时候什么含义都没有，相当于数字0，that you have observed=you have observed, that how you have observed = how you have observed 一样，只是有时候有些人习惯说从句时候开头说个that 说话顿一顿。但是除了that 以外所有的引导词引导从句时（how what where which等等）一个从句开头只能用一次。好，让我们一个一个看，B，that how you have observed=how you have observed 我说过不是一个名词性质的句子，翻译过来是，你怎么看，明显是个状语从句。不选。C how that you have observed更错，首先how 引导就不说了，一看就不能当名词性从句用，后面还放着一个that不知所谓，that想当那个顿一顿无意义的引导词的时候只能发句子开头。D how what？大错特错，首先how 不说了，然后how +what?一个引导词引导一个从句，他两个引导词引导一个从句，一个是怎样看，一个所看到的。刚才说了，一个从句开头只允许一个引导词，不然句意就混乱了。
希望那个对你有帮助。

Answer 2

Professer Lee's book will show you that you have observed can be used in other fields.
李教授的书会告诉你，你所观察到的东西可以用在别的领域
选A

这里的that不是类似于I can tell you that或I can show you that中的that
你可以把that you have observed替换成the things that you have observed，只是the things 省略了而已.
把that you have observed 看做一个整体，这个整体其实是can be uesd...这半句的主语
that you have observed表示你所观察到的东西，you have observed 修饰that，很久不想语法了，可能是同位语吧
如果还原全句，就是Professer Lee's book will show you (that) that you have observed can be used in other fields. 容易混淆的是两个that是不一样的用法
也可以用what替代you前面的that
Professer Lee's book will show you (that) what you have observed can be used in other fields.

Answer 3

选D

解析：该句考查句子结构。其中show后接的双宾语，直接宾语常为疑问副词或疑问代词引导的宾语从句或不定式短语。该题中how引导一个带有主语从句(what you have observed)的宾语从句，what you have observed在宾语从句中做主语，故答案为D。

Answer 4

B.
