It's true that humanity has seen a succession of crises, wars and atrocities, but this negative side is offset by advances in technology and cultural exchanges.
的确，人类经历了一连串的危机、战争和暴行，但科技和文化交流的进步抵消了这些负面影响。
A LITTLE ENCOURAGEMENT
给此刻的你，一点向前的力量。
关于学习、善意与成长，读一句，再想一想。
A man never speaks of himself without losing something. What he says in his disfavor is always believed, but when he commends himself, he arouses mistrust.
谈到自己，一个人总会失去一些东西。人们总是相信他说的对自己不利的话，但当他自我表扬时，却引起了人们的不信任。
Any place that anyone can learn something useful from someone with experience is an educational institution.
任何一个人能从有经验的人身上学到有用东西的地方都是教育机构。
