题目

where 引导的什么时候是地点状语从句...
where 引导的什么时候是地点状语从句?什么时候是定语从句?

答案

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.我买这本书的那个书店离这里不远.
This is the house where I lived two years ago.这就是我两年前住的那个房子.
We will start at the point where we left off.我们将从上次停下来的地方开始.
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 River meet.武汉位于长江和汉江汇合处.
Make a mark where you have any doubts or questions.在有疑问的地方做一个记号.
I found my books where I had left them.我在我原来放书的地方找到了我的书.
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 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.
