- M: Yeah. It was pretty good—it was about barnacles.' B3 j- @' j5 Q) g3 C

. M- ~+ `% i, j9 W* E- M: You know how they stick themselves to stuff in the ocean-link rocks or boats?
9 N/ a7 C# ^# T$ A" u- W: Uh-huh.
( n, \- d2 W3 r f3 @) H- A- M: Well, they do that when they’re young, and then they stay in the same place forever.* ^3 |4 q" D; V7 F% H
- W: It figures. Have you ever tried removing one of those things? Last summer I tried to scrape some off a pier—I had to give up after a while. You’d think they wouldn’t be able to stick like that underwater.
, f [: H- q& c; H" @% @- }- M: That’s one reason scientists are trying to figure ort what their glue’s made of. It’s one of the strongest adhesives in nature. And it’s natural protein, so it probably wouldn’t be harmful like some synthetic glues.$ Z' b$ S, w, s# F' v- S5 h

9 W( ]: T6 a2 s/ V0 ~' E9 y7 p. o; E-Question 39-42. Listen to a talk by an instructor in a biology laboratory.: I8 A. H3 k: }
- W: Before we start our first lab, I’d like to tell you a little bit about the workbook we’ll using. The first thing I’d like to point out is that the workbook contains a very large amount of material---far more than you could ever handle in a single semester. What you’re supposed to do is choose the experiments and activities that you want to do---within a certain framework, of course. Part of my job is to help you make your choices. Next, I’d like to mention that in each workbook chapter, there are usually two subsections. The first is called “Experiments” and the second is called “Activities”. In the “Experiments” section, the workbook gives full instructions for all the experiments, including alternate procedures. Choose the procedure you wish---there’s plenty of equipment available. In the “Activities” section, you will find suggestions for projects that you can do on your own time. You’ll see that there are usually no detailed instructions for the activities---supposed to do them your own way. It there are no question, let’s turn to Chapter One now.
