[问答题]Practice 3　　On his 10-day trip to Asia this week, President George W. Bush is likely to get a polite reception for his ambitious agenda. He wants to rally allies to the war on terror, the confrontation with North Korea and the expansion of transpacific trade. He’ll be asking Japan and China to allow their currencies to get stronger, so they will find it cheaper to buy more goods from struggling US manufacturers. Neither the Japanese nor the Chinese will say no outright, but they won’t say yes, either. Below the polite ambiguities, something disturbing is happening, at least from an American viewpoint.　　For all its military power, political clout and economic might, America could be losing its influence in what is arguably the most dynamic region of the world. Big changes are happening in Asia, for which America’s policies are increasingly out of step. Washington’s preoccupations—-the mess in Iraq, the jobless recovery and the escalating fiscal deficit at home—are not Asia’s preoccupations. When Bush looks into the future, he sees an American Century with a troubled story line dominated by the fight against terror. When Asians look into the future, they see an Asian Century dominated by rising prosperity and the emergence of China, with terror a minor subplot.
