我在大学教经济学。上周一上课前,我兴致勃勃地问学生们周末过得怎样。一个男生说他周末拔了智齿,因此过得不太愉快。随后,他反问我为何总是这么快乐。他的问题令我记起,曾经读到这样一句话:“每天早上当你起床时,你可以选择如何面对一天的生活。”于是我答道:“因为我选择快乐。” I teach economics in college. Before class on Monday, I happily asked the students how weekends were. A boy said he wore a wisdom tooth on the weekend and therefore did not fare so well. He then asked why I was always so happy. His questions reminded me that once read the sentence: “Every morning when you get up, you can choose how to face the day’s life.” So I replied: “Because I choose to be happy.”
