问题  
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、They eat protein.
B、They never move from one location.
C、They cause erosion of rocks.
D、They are found only in deep water.
答案B
解析 这是一道细节题，如果能听出“they stay in the same place forever”这句话，就可看出选项B“They never move from one location”与之完全相对应。另外，通过“Last summer I tried to  scrape some off a pier”这句话，可以判断他们并不是只生活在深水区，因此选项D是不正确的。对于选项A，文中并没有提及藤壶以什么食物为生。选项C文中也没有提到。
