Question

(2013·陕西宝鸡二模)In his absence, I would like to thank all concerned on my brother's ________.

A．behalf	B．part
C．business	D．interest

Answer 1

A

选A　考查名词辨析。句意：我弟弟没在场，我想代表他向所有相关的人员表示感谢。on sb.'s behalf ＝ on behalf of sb.，为固定短语，意为“代表某人”，符合句意。for sb.'s part“就某人而言”；on business“因公”；in sb.'s interest“为了某人的利益”。
