Question

Because they usually receive the same score in the exams, there’s often disagreement as to ______ is the better student, John or Mary.

A．whom

B．which

C．that

D．what

Answer 1

B

试题分析：本题考查宾语从句引导词的使用。本题引导词指人，因为是有范围的选择(John or Mary)，因此用which不用who。句意：因为他们总是得到同样的分数，关于谁是更好的学生，总是有分歧。选B。
点评：考查宾语从句引导词主要看从句的成分，如果是完整的宾语从句，就是that引导定语从句，如果是缺少主宾表，就用what引导，如果缺少疑问词，就看句意。
