当关系词做主语时,关系词后就要加be动词或动词,从句如果是主系表结构的话,那么就要用be动词。
例如: The boy who is under the tree is my brother .
例句中的who在从句中做主语,且构成了主系表结构,所以就要用be动词。例句属于从句把主句岔开了,主句是The boy is my brother;从句是who is under the tree
懂了吗?不懂了再问 望采纳哦~

例如:The boy who often plays the football on the playground is my brother.(这是who做主语的)
I love the girl who I played just now.(who作宾语)
