[00:00.45]M: Good morning , Professor Perkins. I hope I am not disturbing you.
早上好，帕金斯教授，希望没有打扰到您。 [00:04.26]W: Not at all, Tom, come right in. I'm always at my office in the morning.
没关系，汤姆，请进，我早上一直都是待在办公室。 [00:09.30]M: I thought I'd get an early start on my research paper and would like to discuss my topic with you if you have a moment.
如果你有时间的话，我在开始写我的研究报告前想和您讨论我的主题。 [00:17.01]W: Of course. I recommend all my students discuss their topics with me before they begin their research. What do you want to work on?
当然啦，我建议我所有的学生在开始做研究之前和我交流他们的想法。你想往哪方面开始？ [00:26.93]M: I was especially interested in your lecture on dinosaurs and the apparent mystery surrounding their extinction. I'd like to explore that question, but I'm not too sure how to go about it.
我对您关于恐龙的演讲以及有关其灭绝的明显谜团特别感兴趣。我很喜欢去探索这个问题，但是我不确定怎么样去做。 [00:38.76]W: Well, according to the most widely held theory, the dinosaurs died out because of a sudden cooling of the earth's temperature. Your textbook summerizes the conclusions of several paleontologists on this point.
根据最广泛使用的理论，恐龙灭绝是由于地球温度的突然降温。你的教科书总结了几位古生物学家在这一点上的结论。 [00:53.68]M: Didn't you also mention a second theory in your lecture that the dinosaurs may simply have been replaced by mammals gradually and might not have died out as a direct response to the colder weather?
您是否还在演讲中提到第二种理论，即恐龙可能只是逐渐被哺乳动物所取代，并且可能寒冷天气不是恐龙消失的直接原因？ [01:06.40]W: Yes, Van Wehlen and Sloane are proponents of this theory, and I've put some of their articles on reserve in the library.
是的，范·韦伦和斯隆是这一理论的拥护者，我已经把他们的某些文章放在图书馆了。 [01:15.87]M: Van Wehlen and Sloane, I'd better write that down.
范·韦伦和斯隆，写下来最好不过了。 [01:20.30]W: Let me know how your work progresses, Tom. If you should run into any problems, be sure to stop by again.
汤姆，让我了解你的工作进展如何。如果你遇到任何问题，请务必停留下来。
