第十六段
1 .Well, bioluminescence serves a number of functions.

5 .But jellyfish closer to the surface, probably like the jellyfish you saw, they use bioluminescence to hide.
但水母靠近水面，大概就像你看到的水母，它们使用生物发光来进行躲避。
6 .The light they produce matches the color of the dim sunlight, so they blend in, and, uh, and predators can't see them.
它们产生的光和微弱的阳光下相匹配，所以他们融入其中，捕食者就不能发现它们。

这是一个很棒的话题。
2 .But you'll have to make sure the topic is manageable.

3 .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 form bioluminescence in the same way.
正如我说的，大约一半的水母会生物发光，所以你可能想着眼在一个特定类型的水母或若干类型以同样的方式受益于生物发光的水母。
4 .Or you could investigate current research on bioluminescence, on, on the chemical process, or...
或者你可以研究生物发光研究现状，关于化学过程。
5 .Here's an idea.
这里有一个想法。
