犬类杂谈

佛罗里达州盖恩斯维尔——美国约有7000万条狗生活在人类家庭中,比15岁以下儿童还多1000万。其它欧洲国家的情况也大体相似。约有40%的狗狗可以睡在主人的床上。

With cooperation unlikely, the world should prepare itself for the erosion of the World Trade Organization.

    The Globalization of Our Discontent

    Globalization, which was supposed to benefit developed and developing countries alike, is now reviled almost everywhere, as the political backlash in Europe and the US has shown. The challenge is to minimize the risk that the backlash will intensify, and that starts by understanding – and avoiding – past mistakes.

    A Better British Story

    Despite all of the doom and gloom over the United Kingdom's impending withdrawal from the European Union, key manufacturing indicators are at their highest levels in four years, and the mood for investment may be improving.
