where怎么引导了定语从句?
There are information and entertainment services ,where people can download anything from legal texts and lists of “great new restaurants”to game software or dirty pictures.
定语从句的引导词是根据其先行词在从句充当的成份来决定的,先行词在从句中充当状语用关系副词,充当主语或宾语用关系代词.但我发现这好像对限定性定语从句比较好判断,但是非限定性定语从句中先行词有时在从句中不充当成份.
如上句先行词services在从句中充当什么成份呢?
为何用where引导?先行词不是地点呀?
对于非限定性从句引导词该如何使用引导词?
