有读者问： 有一道选择题：
(1)A：_________is the man_________is feeling the elephant over?
B: He is a trainer_________job is to train the elephant.
A. Who...that...whose B. Who...who...whose
C. That...who...whose D. Who...who...who
应选A还是应选B?
这里选A较顺，以避免连用两个who。关系代词that亦可指人，有一位英国学者说过：
(2)We may well speak of the man that built the house.
可见表人的名词之后不一定非用关系代词who不可。
