本月20日,美国新任总统奥巴马正式上任,作为美国历史上第一位黑人总统,这样的情景在上世纪六七十年代美国社会改革以前,完全是不可想象的。然而,肩负着重振国家希望的奥巴马将如何带领这个正陷入经济危机中的国家走出低谷呢?他又将出台哪些新的政策?做出哪些社会变革?他的施政方向又是什么? On the 20th of this month, the newly appointed U.S. President-elect Barack Obama officially took office as the first black president in the history of the United States. Such a scenario was unthinkable before the social reforms in the 1960s and 1970s in the United States. However, how will Obama, who is shouldering the hope of revitalizing the nation, lead this country that is falling into an economic crisis? What new policies will he introduce? What kind of social changes will he make? And what is his policy direction?
