M: Hey, Li Hua, what are you doing here? You taking this class too?

　　L:对，我选了摄影课。可是这节课那么早，我最讨厌起大早。

　　M: Yeah, I'm really bummed that I have to get up so early! I'm also bummed out that Dr. Johnson is teaching this class. I've heard she's really tough.

　　L:嗨，Michael,什么是bummed?我记得Bum不是指无家可归的人吗？

　　M: Yeah, that is true. But here I used bummed and bummed out. They both mean to be unhappy or upset.

　　L:噢，你看，就这一个字就把我弄糊涂了。原来是bummed，或者是bummed out，意思是不高兴，感到烦恼。嗨，Michael,你刚才说什么来着？

　　M: I'm really bummed that I have to get up so early! I'm also bummed out that Professor Johnson is teaching this class.

　　L:现在我清楚了，你是说要那么早起床实在叫你不高兴，Johnson博士教这门课也让你不高兴，因为她很严格。嗨，要是女同学拒绝你的邀请，那你就会更难受，对不对?

　　M: Ha ha. Very funny. But you are right, if I got turned down for a date I'd be bummed. I'm also bummed that summer vacation is over.

　　L:嘿，我可了解你，要是遭到女同学的拒绝，你肯定会垂头丧气的。你连暑假结束也会感到烦恼。不过，这个单词很有用。我希望学期结束时，我不会因为分数不好而感到bummed out。

　　M: Me too. Hey, I got an idea. Let's go to the student center and relax after class.

　　L:我当然知道Johnson博士有多严格。好吧，下了课我们去学生中心休息一下。

　　M: Glad class is over! I'm ready to chill for the rest of the morning. I haven't had a chance to chill out these last few days, getting ready for school and all.

　　L:什么？你说上完课很高兴，但是为什么一上午你会发冷呢？

　　M: Oh, no! Chill or chill out here means to relax. Chill,

　　L:噢，chill或者chill out在这里是指休息。刚才你还说开学前没有机会chill out，到底是什么意思？

　　M: I said: "I haven't had a chance to chill out these last few days getting ready for school."

　　L:原来你是说：过去几天为了准备开学而没有机会休息。

　　那你能说去打棒球，休息一下？

　　M: You normally go someplace calm and peaceful where you can relax. I like to chill out at the cafe with a book sometimes. And I know that you like to chill at the museum.

　　L:打棒球不能说是chill out。不错，要到比较安静的地方才能休息。每个人还不一样，你喜欢坐在咖啡馆里看书，你知道我喜欢到博物馆去。能不能说到酒吧间去chill out?

　　M: Sure, but we usually only say that if the bar is quiet and not too crowded.

　　L:对，要是酒吧间人不多，也不闹，那就能这样说。这个单词太好了。谢谢你教我。我想今晚我到我的朋友家去chill out。

　　M: Sounds great! Ah, look at the time. I need to go meet my friend at the bookstore. Sorry that I have to go, I'm really bummed to have to leave you!

　　L:得了，你要去书店跟朋友一起买书，你就走吧，别说什么跟我分手很难受这种话。走吧，下回我们到别的地方去玩。

　　M: Cool. Have fun chilling tonight at your friends'. See you later!

　　L:我今晚在朋友家肯定会玩得很高兴，Bye!

　　Michael和李华在对话里用了两个常用语，一个是：bummed或者是bummed out,意思是不高兴，烦恼；另一个是：chill或者是chill out，意思是休息，放松，或者玩。
