原标题：拜登：成为美国总统的100天
转眼，拜登入主白宫已满一百天。自罗斯福就任美国总统时提出“第一个百日”概念后，“总统执政百天”逐渐被社会舆论用以评判该任美国总统开局是否良好的重要标志。
那么，拜登在任美国总统的头一百天里，究竟表现如何？
在就职之初，拜登曾表示，美国“有太多要完成，太多要治愈，太多要恢复，太多要建设……”百天之后，拜登向美国民众宣告，美国又向前了。
当地时间4月28日，拜登在国会发表百日演讲。他围绕新政府上任以来颁布的一系列政策展开陈述，力图营造一个在大萧条危机中力挽狂澜的施政者形象。
尽管如此，在大多数美国民众心中，拜登的表现只能算是“差强人意”。多家民调显示，一半的美国民众对拜登迄今为止的表现感到满意，其中调查机构皮尤统计的支持率达到59%。即便这样，拜登百日支持率在历任美国总统中排在倒数第三。
U.S. President Joe Biden gave his first address to a joint session of Congress on April 29, laying out the achievements of his 100 days in office and outlining new legislative goals. Though arbitrary to most casual onlookers, this "honeymoon period" has long been used as an early barometer to gauge the success of an administration.
Biden said "America is on the move again" and mentioned his achievements, such as pushing the $1.9-trillion coronavirus relief package through Congress and administrating 200 million COVID-19 vaccine shots in his first 100 days.
