there are other places where talk loudly is not allowed.talking前为什么不用people are

问题描述:

there are other places where talk loudly is not allowed.talking前为什么不用people are

因为 where 是连接词,引导定语从句,修饰 places.
在定语从句里,talking 是主语,is 是系动词,not allowed 是表语.
如果在 talking 的前面加上 people are,那么这个定语从句里就有两个谓语动词了.
所以不行.
