　　 you may ask your teacher.
　　Son: I asked, but my teacher
　　didn't tell me the answer.
　　Mom: When?
　　Son: When we took our exam yesterday.

　　Every day in Beijing I take a taxi to work and almost every taxi has the same electronic greeting:"Welcome to take Beijing taxi" which they think means "欢迎乘坐北京出租车".The problem is that in English "welcome" usually means "不客气".What they should say is "Thanks for taking Beijing taxi".
　　在北京，我每天都乘坐出租车上下班，几乎每辆出租车上都有相同的电子问候语：“Welcome to take Beijing taxi”，意思是说“欢迎乘坐北京出租车”。问题是，在英语中，“welcome”的意思是“不客气”。它们应该说：“Thanks for taking Beijing taxi”.（我没说“谢谢”，它们怎么说不客气呢？）
　　中国人热情好客，喜欢说“欢迎”——“welcome to”，但是英语不这样说；西方文化讲究礼貌，喜欢说“谢谢”——“thanks for”。
