①We went home, where we had dinner.此句是where引导的"非限制性"定语从句,这里"where"= at home(先行词是home)从句还原" we had dinner at home"全句译:我们回到家,在家里吃了顿饭.
②I walk into the canteen where students are eating此句也是where 引导的定语从句,与上句不同之处在于此句是一个"限制性"定语从句.全句译:我走进了这个同学们都在吃饭的食堂。(限定说明了是一个什么样的食堂)
③地点状语从句与定语从句其本身属性就不同:地点状语从句相当于大的副词;定语从句相当于大的形容词,副词是用来修饰动词的,
例: you can go where you want to go . 你可以去你想去的地方。
