　　鸟类迁徙Bird migration

　　Student having difficulties in writing term paper

　　原文：

　　Conversation：term paper of bird migration

　　Listen to a conversation between a student and his Biology professor.

　　S: Dr. Russell, I was hoping to discuss my term paper with you I'm getting a little bit stuck here.

　　P: Of course, so...what do you have so far? What's your topic?

　　S: Well, I wanted to write about bird migration, but I'm having trouble finding enough sources.

　　P: You're having trouble finding sources on bird migration

　　S: No, actually, on the particular aspect of bird migration that I want to write about.

　　The thing is, I wanted to write specifically on early theories of bird migration...describe some of the theories. Like how Aristotle thought that birds changed into different species during the winter. Or how other naturalists thought that bigger birds carried smaller birds to warmer spots for the wintertime. But I've only got a couple of books to work with right now.

　　P: Hm...I have to admit that it's an interesting topic, and you certainly seem excited by it. But remember I told you all to ask yourselves how your topic is going to help you show that you can apply what you've learned this semester. A summary or description is not really what I'm looking for as much as your analysis of a certain topic.

　　S: I guess it's not really what we're supposed to do, huh

　　P: Right. So, how about we think about some other ideas for your paper. I mean you don't need to discard the idea completely... but... take a really different focus. Um... for example...you could present what you think are some reasons-the rationale-behind some of the erroneous theories early naturalists had. But, you'll be supporting your views with current research; those are the sources you'll need to seek out.

　　S: Ok, I think I see what you're saying. So, like today...today we know that lots of small birds migrate at night, but maybe `cause people didn't see them-didn't see the small birds migrating-they only saw bigger birds, like geese migrating during the day. They thought that the big birds were carrying the small ones under their wings.

　　P: There you go! That's exactly what I mean. You're showing that you're thinking about the topic, not just telling me what you read.

　　S: Ok, I also have a really cool example of a migratory bird that I'd like to discuss in my paper. It's the Common Poorwill—I mean it seems that some Ornithologists believe that the Common Poorwill really does hibernate instead of migrating-that it's maybe the only bird that does.

　　P: If I were you, I would stick just with migration research. Remember, this is only a 15-page paper.

　　S: Ok, I see your point.

　　P: But it's great that you're finding this all so interesting. I want you to come back to see me in a week so we can take a look at the new direction in your paper and evaluate the sources you've found in the meantime.

　　中文粗心:

　　Male Student：教师，我想跟你评论一下我的学期论文。我卡住了，找不到这方面足够的数据。)

　　Female Professor：You can’t find enough sources on bird migration

　　(语调上扬。最终一题，重听题的考点。)

　　Male Student：I wanted to write on theories early bird migration. 关于Aristotle关于这个标题的观点等等。

　　Female Professor：哦～你的确找到了一个好的标题，但是你要知道我的要求是你们的论文要反映你们这学期学了啥。不要仅仅做 summary or description，我想要看到你的special analysis。

　　Male Student：我想，总结和描绘是不行的。

　　Female Professor：没错，不如我们想想别的的方向。本来你不需要彻底抛弃discard之前找的数据，你能够换种想法，用rational 的方法。能够写如今的新研讨(current research) 怎么支撑(support)或许批驳曾经的(historically) old theory。

　　Male Student：我想能够写bird migrate at night。曾经大家大多只看到大鸟，所以以为小鸟在大鸟的翅膀下迁徙啥的，本来新发现是，因为小鸟在夜间迁徙，大家看不到。

　　(经过说这个topic来验证自个理解了教师的目的change the topic from ancient to recent)

　　Female Professor：对，这正是我说的，你要展现你对这个主题的想法，而不是你读了哪些数据。

　　Male Student：I want to write about the birds that do not migrate. They hibernate during winter.

　　Female Professor：如果我是你，我就不会在一份15页的论文中写这么多。

　　Male Student：我知道妳的意思了。

　　Female Professor：期望你一星期内再来找我，看看论文的新的方向(new direction)进行得怎么。

　　Male Student：好的，谢谢。

　　标题：

　　疑问一：Why does the student go to see the professor?

　　答案：(C)he cannot find enough material in writing his paper.

　　疑问二：How does the professor help the student?

　　答案：(A)主张学生改动论文方向。

　　疑问三：What information will the man probably include in his paper (choose two answers)

　　答案：(B)analysis(D)focus on one topic

　　疑问四：Why does the student 说到birds migrate at night?

　　答案：(A)经过说这个topic来验证自个理解了教师的目的he understands what the teacher said.

　　疑问五：Listen again to part of the conversation. Then answer the question.

　　S: Well, I wanted to write about bird migration, but I'm having trouble finding enough sources.

　　P: You're having trouble finding sources on bird migration

　　What does the professor imply when she says this: "You're having trouble finding sources on bird migration... "

　　答案：(B)教授以为找资料很简单

　　背景常识弥补：

　　这篇听力内容，虽然是通常教授与同学评论论文内容的长对话，不过值得注意的是，动物迁徒，包括动物、鸟类、昆虫、乃至鱼类等，生物对栖息地迁徒有关内容，一向不断出如今新托福iBT考题中，不管在听、说、读、写都曾呈现有关考题，因而备考新托福的同学，应当对动物迁徒有必定的知道。

　　Migration Birds Know No Boundaries (鸟类迁徙无鸿沟)

　　¨ The migration of birds is one of the most fascinating and least understood events in nature.

　　¨ Arctic terns are the champions of long-distance migration. They fly about 11,000 miles (17,700 kilometers) from their breeding grounds in the Arctic to their winter home in the Antarctic.

　　Why birds migrate (为啥鸟类迁徙)

　　¨ In many parts of the world, the foods that birds eat become scarce during certain seasons of the year. Most birds would starve if they had to remain in such places through the unfavorable season.

　　¨ Although birds migrate to survive, the factors that actually trigger their migrations are much more difficult to explain. For example, many northern species leave their summer home while the weather is still warm and the food supply plentiful.

　　¨ Bird migrations are probably regulated by the glandular system. The glands produce chemical substances called hormones.

　　¨ Changes in hormone production stimulate the birds to migrate. Among some northern species, hormone production is affected by the length of daylight. As the daylight hours shorten, hormonal changes cause the birds to prepare for their migratory flight south.
