请教where引导的地点状语从句和where引导的定语从句的区别

Question

比如状从Tom put books where it was可否等于定从Tom put books at the place that it was?
还有she is from where the sun rises到底是什么从句？请详析句子结构以及区分方法。谢谢～

Answer 1

状语从句 Tom put a book where it was .在意义上的确可等同于定语从句 Tom put a book at the place where it was.但就英语本身来说，后面这种表达很不地道。
定语从句应该只须抓住三要素：先行词，关系代词或关系副词，另外就是关系代词或关系副词代替先行词在从句中做句子成分。
如：上述定语从句 Tom put a book at the place that it was.中，the place就是先行词， where是关系副词，指代先行词做从句中was的表语，
像状语从句Tom put a book where it was .中，where并不指代任何词语，而主句中基本的句子成分完整，主语Tom ,谓语put（过去时），宾语a book，where引导的句子是为了使主句意义更完善，Tom放了一本书，放了书干嘛？放在它之前在的地方。这样意思才表达清楚。
至于句子：She is from where the sun rises.严格来说，我认为where引导的从句属于介词from的宾语从句，像She is from China.China就是介词from的宾语，只不过这里用一个句子代替，因为＂太阳升起的地方＂没有具体而简单的名次表示，所以就用一个句子了。
希望这些观点能帮上你。

Answer 3

You'd better make a mark where you have any questions. You`d better make a mark at the place where you have any questions. 以上两句字意思相同，但第一个是状语从句，后一个是定语从句。定语从句有先行词THE PLACE，而状语从句没有。状语从句中where引导的句子做地点状语，不出现place. 定语从句出现先行词place，再用where引导的定语来修饰place

Answer 4

Tom put books where it was.=Tom put books at the place where it was.
She is from where the sun rises.= She is from the place where the sun rises.
