问题描述:

He often helps the students _______ he thinks are not so good at English A who Bwhom Cwhose Dthey.

B

A. 在从句中作主语
he thinks 是插入语

选A,这句话意思是 他经常帮助那些他认为英语不够好的人.句子分析的话是He thinks who are not so good at English,and he often helps them.B是宾格不能做“are not so good at English” 的主语 CD两项也都不对

who,定语从句,who在从句中作主语,用主格
