Too much______can possibly lead to unhappiness, even to thoughts of suicide as few people have the courage to analyze themselves objectively and minutely.
【正确答案】 B
【答案解析】本句意为“过多的反省有可能带来不开心,甚至想到自杀,因为很少有人有勇气来客观地、仔细地分析自己”。introspection意为“内省,反省”;retrospect意为“回顾”;perspicacity意为“敏锐”;perspicuity意为“明白”。只有B项符合句意。
