M: Did you watch" Undersea Discovery" last night?
W: No, I missed it. Did you?
M: Yeah. It was pretty good--it was about barnacles.
W:  Hmm.
M: You know how they stick themselves to stuff in the ocean-like rocks or boats?
W:  Uh-huh.
M: Well, they do that when they’re young, and then they stay in the same place forever.
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.
M: Yeah. These biomedical researchers were talking about its possible uses. Orthopedists could use it for mending broken bones; or it could be used in dentistry.
W: I wish I’d seen that.

选项 A、The reproductive cycle of barnacles.
B、A new source of protein.
C、Types of sea animals.
D、The adhesive quality of barnacles.

答案 D

解析 这是一道考主题的题目,通常只要抓住反复出现的词汇就可解题。本文只提到了一种海底生物,就是barnacles(藤壶,附着在水下船底或柱石上的贝属动物),所以可以排除选项C。反复出现的单词是“strongest adhesives(带黏性的)in nature”,“synthetic glues”(胶水),“stick”(粘住)等等,所以可以判断不是在讲barnacles的reproductive cycle,而是讲它们的adhesive quality,所以得出答案D。
