有读者问：有这样一个句子：
(1)Seventeen, she is the daughter of a friend, a woman I love and admire， a woman of accomplishment whose children are accomplished and who love her.
这里为什么用 and who?
and who 常为英美一些人所用, 有时是错用，如句（1）。 从语法结构看，这个 who 与 whose 并列，应与 whose 共用一个先行词 a woman of accomplishment, 但这显然讲不通。从逻辑上看，此 who 应指 children。 所以 and who 是错用了，应去掉 who 才对。这种错用 and who 的情况并不罕见，再如：
(2)Most of the applicants were already working at jobs which did not fit what they had learned and who wanted a move for a variety of reasons, the spokesman explained. （这里的who应为they）
(3)Every male Kaffir must go to a passing office and obtain a form, which he presents to his employer immediately he enters his employ, and who keeps it as long as the Kaffir is with him.
(and who 之前没有与其并列的定语，故属错用；它乃指 his employer, 所以应改为 and the latter)
但还有一种具有争议的情况。比如：
(4)She was a lady very learned in stones, ferns, plants, and vermin, and who had written a book about petals.
对于像这种句子中的 and who, 有人认为不妥，因为它与其前面的形容词短语 very learned in stones... 并不对等并列。有人则认为形容词短语 very learned in stones... 实际上具有与 who 从句同样的句子功用，两者都是 lady 的定语，所以不能算是错误。还有一种人可说是中间派，他们认为这种and who 也常用在优秀作家的著作之中，并不影响读者的理解，所以无伤大雅，充其量仅属微疵而已。但他们又劝人们要避免这种用法，句（4）即可改为：
(5)She was a lady who was learned in stones, ferns, plants, and vermin, and had written a book about petals.
顺便提及，上述结构不仅限于 and who, 还有 but who, and (but)which 等，这里恕不一一举例说明了。
