Question

--- Do you know the girl ________ is in red?
--- Yes, she is my friend, Kate.
A. which            B. who          C. Whom

Answer 1

B

试题分析：句意为;---你认识穿红色衣服的女孩吗？认识。她是我的朋友凯特。在定语从句中，引导词在从句中充当主语，所以选择who，但是如果前面有介词则应用whom，比如说：Lily is my best friendwith whom I spent my happy childhood.which的先行词指物。故应选Ｂ。
