对话
[00:10.20]It's great to meet you, Susie. I've been longing to meet a sociology student on the campus. I'd love to have a talk with you and pick your brains.
苏西，遇到你真是太好了。我一直希望在校园 里遇到一个社会学系的学生。我很想和你谈谈 并且向你请教。
[00:20.96]It's my pleasure to meet a psychology student，actually. There are many things I seem to be unable to understand. For instance, why should we sometimes be down in the mouth while at other times we are in the seventh heaven?
事实上遇到一个心理学系的学生也是我的运 气。我有很多事情难以理解。比如，为什么我 们有时垂头丧气，而有时却十分高兴？
[00:36.51]That's a good question. This usually has something to do with self-satisfaction. If you're not satisfied with something, you are down in the mouth and in low spirits. And if you are satisfied with something , you may become excited or be beside yourself. A:问得好。这通常和自我满足有关。如果你对某 事并不满意，你就会垂头丧气，情绪低落。而如 果你对某事感到满意，你就会情绪高涨，不能自已。
But that depends on how you look at things, doesn't it? So it's personal rather than social.
这就看你凡事怎样想了，对吗？所以这个问题是个体的，而不是社会的。
