All of us communicate with one another nonverbally (不使用言语地), as well as with words. Most of the time, we are not aware that we are doing it. We gesture with eyebrows or a hand,, meet someone else’s eyes and look away, change positions in a chair. These actions we assume are occasional. However in recent years researchers have discovered that there is a system to them almost as consistent and understandable as language.
One important kind of body language is eye behavior. Americans are careful about how and when they meet one another’s eyes. In our normal conversation, each eye contact lasts only about a second before one or both of us look away. When two Americans look searchingly into each other’s eyes, they become more intimate. Therefore, we carefully avoid this, except in suitable situations.
Researchers who are engaged in the study of communication through body movement are not prepared to spell out a precise vocabulary of gestures.

But we do know exactly what information we need to fill in our knowledge, and we have a pretty good idea of how to go about getting it.
Perhaps the best way to think of our present situation is to imagine a train coming into a switch yard(调车场). All of the switches are set before the train arrives, so that its path is completely determined. Some Switches we can see, others we cannot. There is no ambiguity (不明确) if we can see the setting of a switch; we can say with confidence that some possible futures will not materialize (实现) and others will. At the unseen switches, however, there is no such certainty. We know the train will take one of the trac
