分析句子结构:This book will show you what you have observed can be used in other contexts.
This book will show you what you have observed can be used in other contexts.
我想问:1.what you have observed can be used in other contexts.这是疑问代词what引导的宾语从句,作show的宾语;
2.在这个宾语从句:what you have observed can be used in other contexts中what you have observed 又是由what引导的主语从句.
这样看来what承担了两个引导作用,宾语从句和主语从句公用一个连接词可以吗?
能帮我再试举几个宾语从句和主语从句公用一个连接词的例子吗?

,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,This book will show you how what you have observed can be used in other contexts.
疑问代词引导的宾语从句做主语时例句 I know you have what I want

我认为你的分析有错误，what you have observed can be used in other contexts确实是宾语从句，但是不是what引导的，而是省略的that引导的宾语从句中有一个what 引导的主语从句

how 不能省略

英语不咋地，少说为妙

This book will show you ________ can be used in other contexts.
A. how you have observed
B. how what you have observed
C. that you have observed
D. how that you have observed

答：选B
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。

其实是 This book will show you (that) what you have observed can be used in other contexts.
that 引导的动词宾语从句时，不是可以被省去的么？
比如说：I know what he has heard.
