定语从句的主语是哪个?
下面有两个句子,请哪位高手告诉我哪个词是who引导的定语从句的主语啦,
1.He is one of my friends who are working hard.
2.He is the only one of my friends who is working hard.

1.He is one of my friends who are working hard.
引导词who做定语从句的主语,此句中先行词为friends,所以从句中谓语用复数《are》
2.He is the only one of my friends who is working hard.
引导词who做定语从句的主语,此句中先行词为the only one ,所以从句中谓语用单数.
你就记住这个规律:
当one of +名词复数,后跟定语从句时,从句谓语用复数.
当one of +名词复数,前面有the only|the very修饰时,后面的定语从句谓语为单数
