人们说,美国是冷战之后崛起的唯一超级大国,是科技、经济最发达的国家,是21世纪的明星,也将是21世纪的脊梁。 也有人说。美国潜在不少问题。未来岁月,挑战大于机遇,这颗历史巨星会要逐渐沉沦。 在科技迅猛发达,思维日新月异,世界充满变数的时代,要“准确”规划或者预言未来,都是很艰难的事。但人又总离不开评判、比较,以至想象。像美国这样一个举足轻重的世界大国,会长此繁荣昌盛?还是会有所变化?它的 People say that the United States is the only superpower that emerged after the Cold War, the country with the most advanced science and technology and economy, the star of the 21st century and the backbone of the 21st century. Others say. Many potential problems in the United States. In the years to come, the challenges will outweigh the opportunities. This historical superstar will gradually sink. In a time when science and technology are rapidly developing, our thinking changes with each passing day, and the world is full of variables, it is very difficult to plan or predict the future accurately. But people are always inseparable from the judge, more, and even imagined. Will this president, a prosperous and powerful world power like the United States, still have some changes?
