单选题
His constant attempts to ______ his colleagues' achievement eventually caused his dismissal.(2009年北京航空航天大学考博试题)
【正确答案】
B
【答案解析】解析：四个选项的意思分别是：withdraw撤回，取回；diminish轻视，贬低增强；restrain约束，抑制；confine限制，限定。所以正确答案是B选项。如：It’s not fair to diminish her efforts；she’s worked very hard．(贬低她的努力是不公平的，她已非常努力地工作。)
