解析：[听力原文]
What are you expected to do when you have a conversation with an American
题目问你和美国人谈话时，他们会期待你怎么样。原文提到“In other countries，looking into one’s eyes is expected．For example，if you don’t do it in the United States，people may think that you are afraid，embarrassed，or angry”，可见和美国人交谈是要看着对方，否则对方会以为你害怕、尴尬或生气。
