昨天是马丁·路德·金纪念日。他曾说过 Life’s most persistent and urgent question is, ‘What are you doing for others?’ 人生中最为持久、也最为紧迫的问题是：“你为他人做了些什么？”

Yesterday was Martin Luther King Jr. Day . “What are you doing for others?” Martin Luther King Jr. was a minister and activist who was a leader in the Civil Rights Movement. Learn more about this day on the #AmericanEnglish website here > http://bit.ly/MLKdayAE.
