Answer 1

A
试题分析：句意：在桌子上有两顶帽子，其中比较小的那顶是汤姆的。这里是非限制性定语从句，that不能引导非限制性定语从句，故排除B；又因为逗号前后都是句子，所以缺少连词，故排除CD；which在从句中作主语，故选A。
考点：考查定语从句的用法。
点评：本题难度适中。定语从句是高中阶段的重难点之一，也是高考的热点，需要考生有分析理解句子的结构的能力，牢记关系词的用法及区别。
即学即练：He has lots of friends, only a few of  ______ invited to his wedding.
A. whom    B. them       C. which      D. who
解析：B。句意：考查定语从句和其他结构的区别。only a few of them invited to his wedding是独立主格结构，此结构不是完整句子，因此不能选其他引导词。
