All of us communicate with one another nonverbally, as well as with words. Most of the time we’re not aware that we’re doing it. We gesture with eyebrows or a hand, meet someone else’s eyes and look away, shift positions in a chair. These actions we assume are random(随意的) and incidental. But researchers have discovered in recent years that there is a system to them almost as consistent and comprehensible (可充分了解的) as language.
Every culture has its own body language, and children understand its meanings along with spoken language. A Frenchman talks and moves in French. The way an Englishman crossed his legs is nothing like the way a male American does it. In talking, Americans are apt to end a statement with a droop(垂下) of the head or hand, a lowering of the eyelids(眼皮). They wind up(结束)a question with a lift of the hand, a tilt(倾斜) of the chin or a widening of the eyes. With a future-tense verb they often gesture with a forward movement.
