Question

All the students are seated in the classroom,        actually good at their study, listening attentively.

A．most of whom

B．most of who

C．most of them

D．most of which

Answer 1

C

考察句子知识.句意:所有学生都坐在教室里，他们中的大部分实际上很擅长学习，正在聚精会神的听讲。下文为主句的一个分句，省略谓语动词are。选项ACD引导从句，故选C，指代前文all the students，做分句主语。
