Task 2 Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45. 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 (一致的) 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. When an American rubs his nose, it may mean he is disagreeing with someone or refusing something. But there are other possible explanations, too. Another example: when a student in conversation with a professor holds the older man's eyes a little longer than usual, it can be a sign of respect it can be a challenge to the professor's authority it can be something else entirely. The researchers look for patterns in the situation, not for a separate meaningful gesture. Communication between human beings would be just dull if it were all done with words. The main idea of this article is that .
