问题描述:
1.He has made a lot of promises,none of ( )carried out.2.He has three sisters,( )is a doctor.
1.A.them B.which
2.A.all of them B.all of whom C.none of whom
并分析不同之处
答
1.A.them 选B得话后面得加谓语 are
2.C.none of whom 根据从句谓语 is 只能选C为什么要加谓语are,第一个句子是什么句第一句 none of them carrried out ,them 做promises 的同位语, carried out 后置定语。如果用which就是定语从句,从句必须要有完成的主谓语
