Events in the Middle East and North Africa are of historic importance, but
the even bigger, long-term story is the rise of China. What path will it

For decades there has been debate at the highest levels of the Chinese

四月网 2012-02-06
《纽约时报》1月12日报道，原题：美国人如何输掉了iPhone的工作。以下是文章内容
摘编。
中国河南省2010年招聘会上，富士康科技有限公司的求职者蜂拥而至。
去年二月份，巴拉克•奥巴马在加利福尼亚参加矽谷名人们的晚宴，每个客人都
得到了一个向总统提问的机会。
但当斯蒂夫•乔布斯准备发问时，奥巴马总统打断了他，先提出了自己的一个问
题：怎样才能在美国生产iPhone？
不久之前，苹果还在吹嘘它的产品都是在美国生产的，今天事情已经完全不是这样了。
苹果公司去年卖出的7000万部iPhone、3000万部iPad和5900万部其他产品，几乎全是在
海外生产的。
奥巴马问，为什么不能把这些工作搬到家里来做？
乔布斯先生的回答含糊其辞，据参加宴会的人员回忆，他说：“这些工作回不来了。”
总统的发问触及了苹果公司的核心问题所在，这已经不仅仅是海外廉价劳动力的问题了
。苹果高层认为，海外工厂的规模、工人的灵活性、勤奋程度和操作技巧都已经超过了
美国工人。“美国制造”已经不是大部分苹果产品的明智选择... 阅读全帖 |

Owning and driving a car involves two things most motorists would rather

If you do not maintain your car (meaning regular oil changes, filter

The collapse of the Ming Dynasty was a protracted affair, its roots

Originally a vassal of the Ming emperors, Nurhaci in 1582 embarked on an
inter-tribal feud that escalated into a campaign to unify the Jianzhou
Jurchen tribes. Later Nurhaci announced Seven Grievances and openly
