Question

We shouldn't spent our money testing so many people,most of _____ are healthy.

1. A.
   that
2. B.
   which
3. C.
   what
4. D.
   whom

Answer 1

D
思路分析：“most of ________ are healthy”为非限制性定语从句，先行词为“people”，指人，故答案为D，A项that不能用于引导非限制性定语从句；B项which只能指物，C项what不能用于引导定语从句。
点评：本题考查从句的引导词，难度偏难。高考试题会把各种从句的引导词混到一起让考生选择，因此考生必须先理清题目考查的从句属于哪一类从句，然后根据该类从句的特点作出判断。
