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.

A. communication between human beings is usually dull
B. the smallest words are best in effective communication
C. communication without body language would be dull
D. words are not important in communication
