题目内容：

There are other places where talking loudly is not allowed.
分析一下这个句子的成分,places为什么是状语?talking loudly 在定语从句中做主语?什么时候用关系副词?等,

优质解答

places在这是地点名词,where引导的一个定语从句,主句是There are other places.places是先行词,定语从句where talking loudly is not allowed用来修饰places,talking aloudly是非谓语动词,可以起到名词的作用.当主句里主语、谓语、宾语都有的时候,其后的定语从句的引导词就必须用关系副词,可以是when where why.
