Todd在洛杉矶上学，趁着放寒假，要回阿拉斯加去和父母一块儿过圣诞节。今天，他来到一家旅行社定机票。
Professor: Do you visit your parents on the holiday, Winnie? 当然了，我可是孝顺女儿呢！ Agent: Good afternoon sir, may I help you? Todd: Yes, I need to buy a ticket from Los Angeles to the capitol of Alaska. Agent: Alright, when would you like to leave? Todd: I would like to leave December 24th and return January 3rd. 圣诞节是12月25号，Todd要订24号飞阿拉斯加的机票，这可够赶的，万一飞机晚点，他就赶不上和家人过平安夜了。 Professor: Well if his flight is delayed, maybe he could ask Santa Claus for a ride home. 搭圣诞老人的车？哈哈，这可是个好主意！ Todd还说，他要1月3号飞回洛杉矶，这样好，可以在新年夜尽情狂欢后休息一下再出发！ Agent: Do you want a direct flight? Todd: Yes, I want to fly non-stop. Agent: Alright, the cheapest direct flight is $500. Todd: Are there any cheaper flights? Agent: Yes, there is a connecting flight with one layover for $400. Professor: Winnie, do you know what a layover is? 知道啊，如果你坐的不是直达航班direct或是non-stop flight，而是要中途转机的话，这个转机就是layover, layover. Professor: Yes. For example, you can say you had a three-hour layover in Chicago when you flew to New York. 嗯，旅行社告诉Todd说，直飞票要500块，有一个layover的便宜些，400块。不知道Todd会买哪种。 Todd: Well, I'll take the direct flight. Agent: Where would you like to sit? Todd: Is there an aisle seat available? Agent: No, there is only a window seat. Todd: Alright, I'll take the window seat. Professor: Winnie, do you like sitting in the window seat or the aisle seat? Window seat就是靠窗的座位，aisle seat则是靠过道的座位。我倒是无所谓，坐哪儿都行，不过千万别有个大哭大闹的孩子坐在我旁边！ Professor: Yes, I really hate it when there is a crying baby near me on a plane. I can never fall asleep. Agent: Would you like to fly first-class? Todd: How much does a first-class ticket cost? Agent: A first-class ticket is $3,000. Todd: Umm ... I think I'll just fly in the economy class. 头等舱要三千块啊！比经济舱贵好几倍！Professor Bowman，你知道吗，我的梦想就是，有朝一日发了财，一定要到头等舱过把瘾！ Professor: Well, there is another way to reach your dream. You could earn frequent flyer miles. Frequent flyer miles? 就是常飞客积攒的里程数吧？对！这也是个好办法，可以用里程换积分，攒够了升级坐头等舱！ Professor: Yes! You know, sometimes people also call economy class "coach." 哦，原来economy class和coach都是经济舱的意思，不过要我说啊，叫“沙丁鱼舱”更合适！ Todd: What if I need to cancel my trip for some reason? Can I get a refund? Agent: You can get a refund if you cancel your trip one day before you leave. Todd: What if I need to cancel my trip at the last minute? Agent: In that case, the tickets are non-refundable. Professor Bowman, 什么叫 at the last minute？ Professor: If you did something as late as possible, you can say you did it at the last minute. For example, "I wasn't going to give any homework at the end of class, but then I changed my mind at the last minute." 哦，就是到最后一分钟才临时决定做什么事。旅行社的人说，Todd如果在出发当天才突然改变主意，就不能退票了。看来他还在犹豫到底是不是要回家，所以才会问退票的事吧？ Professor: Let's tune in next time and find out! 这次的美语三级跳就播送到这里。
