Recently I was an observer at _____ parent education seminar about the depression, suicide, and anxiety disorders affecting _____ children.

A．the ; the

B．the ; a

C．a ;

D．a ; the

答案

C

解析

试题分析:考查冠词用法。从语境判断seminar不是特指某一个研讨班，而仅指“一个研讨班”；而且children指所有的孩子们，也是泛指概念，所以C选项正确。句意：最近我做了一个家长教育研讨班的旁听者，这个研讨班是关于抑郁、自杀和影响孩子们的焦虑性障碍的。
