Americans have been sending the President turkeys for the holidays since at least the 19th century. The White House says Abraham Lincoln may have been the first to decide to let a turkey live, and George H.W. Bush gave the first formal presidential pardon in 1989. [Zhang Jun/Xinhua]

美国人在感恩节给总统送火鸡的习俗始于19世纪。据白宫方面称，林肯是头一位对火鸡“手下留情”的总统；而火鸡第一次得到正式赦免则是在1989年，老布什总统当权时代。（新华社记者张军摄）
