问题
选择题
Several professors from Peking University came to visit our school, to my surprise, one of ________ was my aunt.
A．them
B．those
C．which
D．whom
答案
答案：D
题目分析：考查非限制性定语从句，先行词是Several professors，定语从句中one of后面用关系代词whom引导定语从句，句意：几个来自北京大学的教授来参观我们学校，使我惊讶的是，一个是我阿姨。选D。
点评：考查定语从句一要看先行词，而要看从句的成分，如果缺少主宾表，要用that或which,如果定语从句中缺少介词，可以用介词+whom/which.
