单选题 The passage mainly discusses the problem that ______.

A、 people are easily cheated when they buy something
B、 people are afraid to speak for themselves
C、 some people think too low of themselves
D、 some people are afraid of superiors

【正确答案】 C

【答案解析】[试题分析] 文章主旨题。
[详细解答] 题干要求实际上是归纳文章的中心。文章由三个问题引入话题，谈到了许多人都不能正视自我，然后根据艾尔波特的话直接说出症结，然后又通过AT课程的成功经验分析只要克服了恐惧心理就能重新认识自我，实际上都是围绕许多人看低自己来展开的，因此，C为正确答案。
