问题描述:

This book will show you ___ can be used in other contexts.A.how you have observed B.how that you have observed
C.that you have observed D.how what you have observed
我不明白为什么要加how

简单一点说,"what you have observed"可以被看作一个整体,意思是"你观察到了的"
整句的意思就是:这本书会告诉你你所观察到了的是怎样在其它文章中应用的.

show的宾语是how...can be used这句话,what you have observed是这句话的主语。

这本书可以告诉你,你所观察的怎样运用在别的背景下..
how这里表示怎么运用的意思.what you have observed 整个看作一个整体sth
就可以看成 how sth can be used in other contexts

这是句how引导的宾语从句,what you have observed 是从句的主语
