阅读下面文章，完成小题。
                                                                                                              品味瑕疵
        ①我国有“金无足赤，人无完人”的谚语，英谚也有“世上没有不长杂草的花园”之说。由此看来，任何事物都有缺点，都有瑕疵。如何对待这些瑕疵，却因人而异：有些人斤斤计较，换得的是不满和不快乐，而有些人却学会品味瑕疵，从而收获了很多。 
        ②瑕疵铸就了别样的美。最美女神维纳斯，成就其美的，不是无瑕绝伦的美貌，不是艺术家高超的技艺，而是一双无法修复的手臂。两只残缺的手臂，却激发了人们无穷的想象力，从而成就了一种撼人心魄的艺术美。月缺是瑕疵，但是“无言独上西楼，月如钩，寂寞梧桐深院锁清秋”中那一弯如钩的月，却把李煜的国破家亡之恨、孤独寂寞之情渲染得如此传神，从而写出了深深触动我们内心的凄清之美。正是瑕疵，酝酿出这些别样的风景。
        ③瑕疵也能超过完美，创造奇迹。在美国有个叫拉里恩的玩具商人开办了一家玩具娃娃公司，设计了一个可爱的娃娃名为Bratz，却总是无法超越完美的经典——诞生于1959年的芭比。当他为此苦恼时，他那只有7岁的孩子不小心把几滴墨水溅到娃娃脸上，令他感到意外的是，对这个脸上有瑕疵的娃娃，孩子反而更喜欢了。“你不觉得他跟我很像吗？看他那一脸的雀斑，很可爱！”他的孩子指着娃娃脸上的污渍说。拉里恩得到启发，大胆地设计了有五位成员的娃娃组合，最主要的是她们脸上都有一些雀斑，这就是如今的Bratz。经过十年的发展，拉里恩用持续市场销量说明了Bratz已经成为了世界上最受欢迎的玩具娃娃。美国《时代》杂志这样评价说：“拉里恩创造了一个不可思议的奇迹——用瑕疵超越了完美的经典！”
        ④品味瑕疵，能战胜挫折，获得更大成功。司马迁身受大刑之辱，成为了他人生中抹不去的瑕疵，可他并没有因此消沉，却将此作为激励自己的动力，奋笔疾书，夜以继日，终于完成了《史记》而声誉斐然。卓别林因为相貌丑陋而被很多工作拒绝，但在喜剧方面逐渐显露出了他的优秀之处，从此，一位著名喜剧大师诞生了。正是他的瑕疵成就了他的事业。然而也有一些人却不是这样，比如一些运动员在自己事业上升时期，为了有个完美的结局，想方设法回避该有的挑战，早早结束运动生涯，失去了获得更大成功的机会。因此，有时瑕疵虽然使我们的人生不完美，却激发出更大的能量，绽放出更美丽的花朵。
        ⑤尼采说：“追求完美是正常而有缺憾的人性。”允许瑕疵的存在，是人生淡然的大智慧。学会品味瑕疵，才能感受到不完美的完美，才能创造奇迹，才会收获更大的成功。
