where引导的定语从句和地点状语从句的区别是什么？_dhy where地点状语从句

最简单的办法是看where是否有指代先行词
应到定语从句还是状语从句的区别主要可以从以下三点来看：
一、where引导定语从句时, where是关系副词, 在从句中作地点状语, 其前面有表示地点的先行词,where引导的从句修饰先行词。例如:
The bookshop where I bought this book is not far from here.
This is the house where I lived two years ago.
We will start at the point where we left off.
二、where引导状语从句时, where是从属连词, where引导的从句修饰主句的谓语动词,where前面没有表示地点 的先行词。例如:
Wuhan lies where the Changjiang River and the Han Jiang Rivermeet.
Make a mark where you have any doubts or questions.

I found my books where I had left them.
有时, where引导的地点状语从句兼有抽象条件含义, 可放在主句的前面, 而where引导的定语从句则不能。例如:
Where there is a will, there is a way. 〔谚语〕有志者事竟成。
Where there is water, there is life. 有水的地方就有生命。
三、在有些情况下, where引导的定语从句可转换为where引导的地点状语从句。例如:
A tall building was put up at the place where there used to be adesert. （＝A tall building was put up where there used to be adesert. ）在以前曾是沙漠的地方盖起了一幢高楼。
Bam boo grows best in places where it is warm and where it rainsoften. （＝Bamboo grows best where it is warm and where it rainsoften. ）温暖而多雨的地方最适合于竹子生长。
