M: Have you done the lab experiment for physiology yet--the one on taste?
W: Yeah, it was kind of fun--mapping the taste buds. Didn’t you think so?
M: I’m doing it this afternoon. How long will it take?
W: It went pretty quickly--under an hour, anyway. See, first you mix up the four solutions.
M: You take water and add either sugar, lemon juice, salt, or... uh... What was it?
W: Bitter quinine.
M: That’s it... uh... then what?
W: Then all you have to do is taste each sample and describe where each flavor seems most intense.
M: Is that hard?
W: Not really. One thing to remember though--not all the taste buds are on the tongue.
M: Right. I’ll keep that in mind. And thanks for going over this with me. Maybe we could talk about this after I’ve tried it--we could get a pizza or something.
W: Great. Give me a call.
选项 A、To see how certain chemicals produce different flavors.
B、To determine if a person can distinguish salty and sweet solutions.
C、To map the location of taste buds.
D、To count the number of taste buds.
答案 C
解析 这道题需要考生听出“mapping the taste buds”，意思是“测定味蕾的分布位置”。或者是通过后面W所说的“并非所有味蕾都在舌头上”，也可以大致推测出实验的主要目的是选项C。
