同学你好~

这里where引导定语从句，在从句中作地点状语。

定语从句是用来修饰一个名词的，如果是where引导的定语从句，那么先行词应该是一个表示地点的名词，用来说明说明那是一个什么样的地点。

而如果是where引导的地点状语从句，则用来修饰句子的谓语动词的，说明那个动作发生的地点的。

定语从句
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.
注意都有一个表示地点的词

状语从句
Wuhan lies where the Changjiang River and the Han Jiang River meet.
Make a mark where you have any doubts or questions.
I found my books where I had left them.
没有表示地点的词

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 a desert. （＝A tall building was put up where there used to be a desert. ）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 rains often. （＝Bamboo grows best where it is warm and where it rains often. ）温暖而多雨的地方最适合于竹子生长。

祝同学学习进步~
