单项选择题

All of us communicate with one another verbally (口头的) as well as non-verbally. Most of thetime we are not aware that we’re doing it. We wave a hand, meet someone else’s eyes or lookaway, shift positions in a chair. We make these movements unconsciously. But researchers havediscovered that there is a system to them almost as consistent (一致的) and comprehensible aslanguage.
Every culture has its body language. The way an Englishman crosses his legs is nothing likethe way a male American does it. In talking, Americans are likely to end a statement with a lowering of the eyelids. They conclude a question with a lift of the hand or a widening of theeyes. With a future-tense verb they often gesture with a forward movement. There are regionalidioms too. Your sex, ethnic background, social class and personal style all influence your bodylanguage. Nevertheless, you move and gesture within a certain idiom.
Usually, the wordless communication acts to qualify the words. What the non-verbal elements express very often, and very efficiently, is the emotional side of the message. When a personfeels liked or disliked, often it’s a case of "not what he said but the way he said it."
Experts in the study of communication through body movement are not prepared to spell outa precise vocabulary of gestures. When an American rubs his nose, it may mean he is disagreeingwith someone or rejecting something. But there are other possible interpretations, too. The expertlooks for patterns in the context, not for an isolated meaningful gesture.
