Student: So then I read the part about dialect accommodation. You know, the idea that people tend to adapt their speaking to make it closer to the speech of whomever they’re talking to, and I’m thinking, yeah, I do that when I talk with my roommates, and without even thinking about it or anything, you know. 学生说自己读了有关方言的适应性的章节，人们在聊天时会调节自己的口音，让听的人尽量听懂。确实如此，我和室友聊天时也是潜意识的这样做。所以选项 A 和 C 正确，即人们调节口音是一种潜意识的行为，并且这一行为现象是很普遍的。

答案: AC
