I'm taking this great course Psychology of Language, it's really interesting. Since you're psychology major, you should sign up for it. Actually I tried to do that, but they told me I had to take language studies first. What do we learn from the conversation? 我选了“语言心理学”这门有趣的课程。因为你是心理学专业的,你最好也选这门课。 其实我去报过了。但是他们告诉我,让我先学语言学。 我们从这个对话中学到了什么?
