在托福考试当中，每个词都认识，但就是听不懂？听力对话模拟的是学生在美国大学校园当中会碰到的生活和学术场景，在对话里面或多或少会有一些大家从来没有接触过的口语化表达。

1. don’t sell yourself short

Professor ：
Hey, don’t sell yourself short. People your age are a very attractive market for advertisers who promote their products on television. (TPO18C2)

Student: Could you, could you possibly check? I know it s a long shot but …my friend Susanne, she takes photography classes in Harrison Hall and...um...she sort of thought there might be an opening in the janitorial staff. (TPO48C1)
