听力原文：M: Hi, Sue.
W: Hello, Jill, how are you？
M: I'm fine. Did you watch the TV special about barnacles last night？
W: No, I missed it. What did you learn about them？
M: They glue themselves to rocks in the ocean, shortly after birth. They also stay in the same place forever.
W: Right, have you ever tried removing one of these things？ It would be easier to chip the rock away than to get the barnacles off.
M: Exactly, and that's why scientists are trying to figure out what the barnacles glue is made of. It's considered one of the strongest adhesives in nature.
W: And it would have the advantage of being able to work on wet surfaces too.
M: Precisely, and because it's natural protein, it probably wouldn't be harmful to people like so many synthetic glues in use today.
W: Think of all the ways in which doctors and dentists could use such a glue to mend broken bones and fasten false teeth.
M: There could be countless uses. Scientists hope to learn soon exactly how the glue is made, so that people can make use of it.
W: That's good news for the general public. I hope it won't take long for the new glue to be put into use.

听力原文：M: Hey, Karen. Look like you've got some sun.
W: I guess so. I spent the weekend on the beach.
M: Really？ That sounds great. Where did you stay？
W: Some friends of my parents live there. They invited me there for as long as I want to stay.
M: So why don't you stay there for a longer time？
W: Oh, I have a paper to work on. And I just couldn't do any serious studying on the beach.
M: I don't blame you. So what did you do out there？ I mean besides lying out in the sun.
W: I played some volleyball. I never realized how hard it is to run on sand. I couldn't get through a whole game because I had to sit down. It's much easier to run on wet sand near the water.
M: It must be cool. Did you go swimming？
W: I intended to. But they said the water wasn't warm enough for that. So I just wetted in up to my knees.
M: All sounds so relaxing.
W: How about your weekend？ Don't tell me you spent it in the library again.
