我答应过我的女朋友过生日进送她一条金项链。可是当珠宝商报出我们看中的那条项链的价格时，我低低地打了个长口哨。“那这条项链多少钱呢？”我指着另一个盘子里的项链问。

“先生，对你来说，”珠宝商答道，“大约值三声口哨。”

I promised my girlfriend a gold necklace for her birthday, but when the jeweler quoted a price for one we liked, I let out a long, low whistle. And how much are they then I asked, pointing to another tray.

You, sir, replied the jeweler, about three whistles.

区别

“研究生班和本科生很容易就能区别开来，”在洛杉矶加利福利亚州立大学给我们研究生上工程学课的老师如此说。“我说‘下午好’，本科生们回答说‘下午好’。研究生们则把我说的话记在笔记本上。”

Difference

＂I can always tell a graduate class from an undergraduate class,＂ observed the instructor in one of my graduate engineering courses at California State University in Los Angeles. ＂When I say, 'Good afternoon,' the undergraduates respond, 'Good afternoon.＂ But the graduate students just write it down.＂
