模仿文本：A pessimistic world view does not have to entail a life stripped of joy. Pessimists can have a far greater capacity for appreciation than their opposite numbers for they never really expect things to turn out well. And so they may be amazed by the modest successes which occasionally break out across their darkened horizons. 

 

译文：悲观的世界观未必导致人生乐趣全无。悲观主义者比其他人更能欣赏全世界，因为他们从不真心期待发生好事，所以在他们阴郁的世界里，偶尔爆发一次普通的成功，也会让他们感到惊喜
