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、It works on wet surfaces.
B、It’s stronger than synthetic glue.
C、It’s a nutritious source of protein.
D、It has been used successfully by doctors.
答案A
解析 “You’d think...”的意思是“你会认为……”，实际上这里肯定表达了否定，恰恰表达了“barnacle”在海底也具有极强的黏性，这也正是科学家们感兴趣的原因，故答案A与之相对应。
