托福TPO/Official 26 Con 2听力原文According to the professor, why were the jellyfish that the student saw glowing?-新东方托福官方网校手机版

旁白：听一段学生和她生物教授的演讲。

Narrator: Listen to a conversation between a student and her biology professor.

教授：你好，简。会议怎么样啊？

Professor: Hi, Jane. How was the, uh, the conference, right?

我遇到了很多在那个地方工作的人，他们来自非常棒的机构。

I met a lot of people from some really amazing organizations that are working in the area.

现在，让你学生你们在社区里做志愿者已经容易多了。

Now it would be a lot easier to get students to volunteer in the community.

加上，我从来没有去过这些沙滩。

Plus, I've never been to any of the beaches here before.

可以在沙滩绝对是一个额外的好处。

Being at the beach was definitely a plus.

教授：我希望你有时间看一下你在课上错过的笔记。

Professor: Well, I hope you had time to look over the notes from the class you missed.

学生：是的。在明天上课之前我会仔细看一下的。

Student: Yup. I'II look them over before tomorrow's class.

教授：很好。如果有问题就告诉我。

Professor: Good. And let me know if you have any questions.

学生：我现在有一些问题想要问。

Student: Well, there is something that I wanted to ask you now.

It's about something I noticed at the beach.

学生：那里有很多水母，飘在水里。

Student: Well, see, there are a lot of jellyfish there, floating in the water.

教授：那可能听上去让人不舒服。

Professor: That couldn't have been pleasant.

学生：对于游泳来说真的不太爽。

通常我们会在后半学期讨论这个。

And actually we are going to talk about it later in the semester.

生物体之发光主要是由化学反应产生的光。

Basically, bioluminescence is light that's produced by a chemical reaction.

教授：不是所有的水母，大约一半。

Professor: Well, not all jellyfish, about half of them.

事实上，很多海洋生物有这种能力，尤其在海洋深处。

Actually, a lot of marine organisms have this ability, especially in deeper parts of the ocean.

就像是它变得越黑，鱼更多的鱼就需要光，对吗？

Like the darker it gets, the more the fish needs light, right?

教授：生物体之发光起到了很多功能。

Professor: Well. bioluminescence serves a number of functions.

大部分的水生生物用它来交流，来吸引猎物。

Most aquatic organisms use it for communication and for attracting prey.

但是水母通常用它来防御捕食者。

But jellyfish usually use it as a defense against predators.

一些水母会制造出明亮的闪光，这些闪光会迷惑捕食者，会惊吓到它们。

Some jellyfish produce bright flashes of light that confuse predators, to, uh, to startle them.

但是，离表面较近的水母，可能就像你看到的水母，它们利用生物体之发光去隐藏。

But jellyfish closer to the surface, probably like the jellyfish you saw, they use bioluminescence to hide.

它们产生的光和昏暗的日光的颜色吻合，所以他们可以混合进去，然后捕食者就看不见他们。

The light they produce matches the color of the dim sunlight, so they blend in, and, uh, and predators can't see them.

学生：真的吗？我正在为我的论文寻找主题，也许我可以用发光的水母作为主题。

Student: Wow, really? Well, I am looking for a topic for my term paper, so maybe I could do it on these glowing jellyfish.

这是我为什么来问你和它们发光的问题，去看看是否真的有东西可以写。

That's why I wanted to ask you about them, you know, to find out if there was really something to write about.

但是你必须确定这个话题是可以操作的。

But you'II have to make sure the topic is manageable.

就像我说的，大约有一般的水母是生物体发光的，因此你可能想要着手于某种或者一些特定的水母，这些水母以同样的方式通过生物体发光来获益，或者你可以调查一下当今关于生物体发光的研究，关于化学过程，或者，这里有个想法。

Like I said, about half of all jellyfish are bioluminescent, so you may want to look at a particular type of jellyfish or several types that benefit from bioluminescence in the same way, or you could investigate current research on bioluminescence, on, on the chemical process, or, here's an idea.

You seem to be very involved in local issues.

看看你是否能够识别你在沙滩上看到的水母并以及它们时如何融合到当地的生态系统中去的。

See if you can identify the jellyfish you observed on the beach and how they fit into the local ecosystem.

学生：上星期我碰到的一些环境组的人可能可以帮助我。

Student: Yeah, you know, some of the environmental groups I met last week might even be able to help me.

Why does the student go to see the professor?

What does the student say about the conference she attended?

What caused the woman to become interested in bioluminescence?

According to the professor, why were the jellyfish that the student saw glowing?

What does the professor imply about the student's proposed research topic?

Narrator Listen to a conversation between a student and her biology professor． Professor Hi, Jean．How was the…uh, the conference, right? the conference on volunteerism? That’s where you were last week． Student Yeah. It was great. I met a lot of people from some really amazing organizations that are working in the area．Now it would be a lot easier to get students to volunteer in the community．Plus, I’ve never been to any of the beaches here before．Being at the beach was definitely a plus． Professor Well, I hope you had time to look over the notes from the class you missed．You did get the notes, right? Student Yup．I’ll look them over before tomorrow’s class． Professor Good．And let me know if you have any questions. Student Well, there is something that I wanted to ask you now．It’s about something I noticed at the beach． Professor Oh, what’s that? Student Well, see, there are a lot of jellyfish there, floating in the water. Professor That couldn’t have been pleasant. Student Not for swimming. But it was interesting. I mean, the jelleyfish were glowing．I swear they were．And I am wondering what that’s about． Professor Ah, glowing jellyfish．That is interesting. Uh, it’s called bioluminescence．And actually we are going to talk about it later in the semester．Basically, bioluminescence is light that’s produced by a chemical reaction. Student Really? Inside the jellyfish? Professor Well, not all jellyfish, about half of them．Actually, a lot of marine organisms have this ability, especially in deeper parts of the ocean． Student Oh? I get it.
