听力原文：

Ross:And everyone's telling me, you gotta pick a major, you gotta pick a major. So, on a dare, I picked paleontology. And you have no idea what I'm saying, because, let's face it, you're a fetus. You're just happy you don't have gills anymore.
Carol:Look, you don't have to talk to it. You can sing to it if you want.
Ross:Oh, please. I am not singing to your stomach, ok?
