问题补充：
We are in great need of a more capable manager, with straightforward persona
lity as well as good humor.
A. the one
B. who
C. which
D. one
答案：
A. the one
B. who
C. which
(答案→)D. one
解析：选D考查代词。句意：我们急需一名更能干的经理，他要有直率的性格和良好的幽默感。分析句子成分可知，空处不引导从句，故排除B、C两项；而one ＝ a manager, the one ＝ the manager，这里指代的是a more capable manager，故选D。
