    We want our children to succeed, in school and, perhaps even more importantly, in life. But the paradox(悖论) is that our children can only truly succeed if they first learn how to fail. Consider the finding that world-class figure skaters fall over more often in practice than low-level figure skaters. At first sight this seems contradictory. Why are the really good skaters falling over the most?

    The reason is actually quite simple. Top skaters are constantly challenging themselves in practice, attempting jumps that stretch their limitations. This is why they fall over so often, but it is precisely why they learn so fast. Lower-level skaters have a quite different approach. They are always attempting jumps they can already do very easily, remaining within their comfort zone. This is why they don't fall over. In a superficial sense, they look successful, because they are always on their feet. The truth, however, is that by never failing, they never progress.

    What is true of skating is also true of life. James Dyson worked through 5,126 failed prototypes(原型) for his dual cyclone vacuum before coining up with the design that made his fortune. These failures were essential to the pathway of learning. As Dyson put it: “You can't develop new technology unless you test new ideas and learn when things go wrong. Failure is essential to invention.”

    In healthcare, however, things are very different. Clinicians don't like to admit to failure, partly because they have healthy egos(自我)(particularly the senior doctors) and partly because they fear litigation(诉讼). The consequence is that instead of learning from failure, healthcare often covers up failure. The direct consequence is that the same mistakes are repeated. According to the Journal of Patient Safety, 400,000 people die every year in American hospitals alone due to preventable error. Until healthcare learns to respond positively to failure, things will not improve.

    But let us return to children. One of the major mistakes in education in the 1970s was the attempt to equip children with confidence by giving them lots of successes (setting the bar very low). The consequence was that the ego of kids became bound up with success, and they became unable to take risks and collapsed as soon as they hit a proper challenge.

    We need to flip(翻转) this approach. In a complex world, failure is inevitable. It is those individuals and institutions that have the flexibility to face up to failure, learn the lessons and adapt which eventually excel(突出).

阅读材料,完成下列要求。

材料一:2016年7月12日,中菲南海争议仲裁庭罔顾基本事实,肆意践踏国际法和国际关系基本准则,公布了严重损害中国领土主权和海洋权益的所谓“裁决”。月13日,国务院新闻办公室发表的《中国坚持通过谈判解决中国与菲律宾在南海的有关争议》白皮书强调,中国尊重和践行国际法,在坚定维护中国在南海的领土主权和海洋权益的同时,坚持通过谈判协商解决争议,坚持通过规则机制管控分歧,坚持通过互利合作实现共赢,致力于把南海建设成和平之海、友谊之海和合作之海。白皮书表示,中国将处于地区国家共同维护南海和平稳定,坚定维护各国依据国际法在南海享有的航行和飞越自由。对此,国际社会广泛支持中国南海问题立场,70多个国家明确表态不承认南海仲裁结果。

材料二:2016年2月2日,春节前夕,******如约来到江西。在井冈山革命烈士陵园,***表示,要让广大党员干部知道现在的幸福生活来之不易,多接受红色基因教育。这并不是***首次向广大党员干部强调党的优良传统的重要性。

十八大以来,***的足迹已经遍布革命老区:河北西柏坡、山东临沂、福建古田、陕西延安铜川、贵州遵义、江西井冈山…… 革命老区有优秀的红色精神。

***多次到老区,既是对老区人民生活的牵挂,也是对广大党员干部的精神洗礼。正如***所说:“每来一次,都能受到一次党的性质和宗旨的生动教育,就更加坚定了我们的公仆意识和为民情怀。历史是最好的教科书。对我们共产党人来说,中国革命历史是最好的营养剂。多重温这些伟大历史,心中就会增加很多正能量。”
