名人教英文：全球面临的三大挑战

全球政治和经济危机四伏，但是美国前总统克林顿在time撰文说我们有乐观的理由。
他的文章题为the case for optimism。case除了解作“盒子”、“个案”之外，还解作“理由”。the case for相等于the arguments for。例如：the case for equal pay for everyone has not been made.

克林顿指出全球面对三大挑战：inequality（贫富悬殊）、instability（政经动荡）和unsustainability（不能持续的资源使用方式）。他举例："the fact that half the world's people live on less than $2 a day and a billion people on less than $1 a day is stark evidence of inequality." "the way we produce and use energy is unsustainable, changing our climate in ways that cast a shadow (近义语为cast a pall，即“布下阴霾”) over our children's future."
