CAMBRIDGE – The Nobel laureate economist Paul Krugman once quipped that “Canada is essentially closer to the United States than it is to itself.” After all, most of its citizens live in a narrow band along the more than 3,000-mile-long border.
美国剑桥—诺贝尔经济学奖获得者保罗·克鲁格曼（Paul Krugman）曾讽刺说，“加拿大其实与美国比与它自己更接近。”毕竟，大部分加拿大公民都生活在3,000多英里长的加美边境周边狭长带中。大部分加拿大人住得离更多美国人而不是加拿大人更近。
