【地点状语从句】where引导的定语从句和地点状语从句的区别是什么?

【答案】 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 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.）温暖而多雨的地方最适合于竹子生长.
