有一读者问： 有这样两道辨错题：
(1) Mr. Snow is one of those men (A: who appears) to be (B: friendly) however, it is very hard to (C: deal with) (D: him).
(2) Marion is only one of the students (A: in the class that) never (B: admit making) a mistake, (C: even when it) (D: is pointed out) to him.
上述第一道题的答案是A错，应改为appear;第二道题的答案是B错，应改为admits making。上述答案对否？
上述答案是对的。句（1）按其句意来讲，who之后显然应用复数动词appear，因为who的先行词在此不是one，而是men。句（2）按其句意，that之后显然应用单数动词admits,因为that的先行词不是students,而是one。
但应指出，上述句（1）用单数动词appears是英美人常犯的错误，再如：
(3)This is one of the doors that was damaged.
按理说，这里不应用was而应用were,因为that的先行词显然是doors（当然也有可能是one,但这种情况较少）。有人说这里之所以用单数动词was是因为受了one的影响的缘故。由于受到one的影响而用单数动词的情况还有如：
(4)More than one question was asked.
