Uses of interrogatives as pronouns In English, interrogatives are occasionally used as not as interrogatives but as adverbs and relative pronouns. For example: I don't know why we moved; I don't know how that machine works; I know where she lives; I don't know what she does for a living； I don't know whom she married. Could you use 为什么，怎么，哪里，什么，谁 here, and if not, how would you structure these and similar sentences? 谢谢!
You'll never be able to map one to one English to Chinese, but some things are expressed in a very similar manner in both languages, simply because that is convenient and efficient, I believe.

Relative clauses in Chinese don't follow the English pattern though.

That is the dog [that bit me].
这是那条[咬我的]狗。(Just stick the relative clause content in front of the noun)

I don't know why we moved.
我不晓得我们为什么搬家。
I don't know how that machine works.
我不知道那台机器怎么运作。
I know where she lives.
我不知道她住在哪里。
I don't know what she does for a living.
我不知道她靠什么生活。
I don't know who she married.
我不知道她和谁结的婚。
