| The eyes are one of the most expressive instruments of body language. Keith, seventeen, from Montclair New Jersey, learned the hard way about one 1 the eyes can make. "I had a teacher who graded heavily on classroom discussion," Keith says. "He seemed to have a strong ability to know just when I didn't have the 2 . I couldn't figure out how he could be so sharp. Then it dawned on (为……所明白) me. 3 I didn't know the answer, I would avoid looking at him. When I did know what to say, I always 4 straight back at him. From that moment on, I taught myself to look him in the eye, 5 I knew the work or not. That trick has saved me a lot of trouble." Many people,including some policemen,believe eye contact is a good test of honesty. If someone can't look at you directly in the eye,then he or she is not playing 6 , they insist. After many experiments, however, a number of experts have found out that good liars can make false eye contact. Eye contact, though not a(n) 7 sign of honesty, is a clear way to show interest in another person. When a person looks at you and continues to do so,you know his 8 is placed on you. When he turns his head away, his mind is probably elsewhere. 9 there are exceptions. A shy person may have trouble making and keeping eye contact, no matter how interested he is in the other person. And certain 10 , such as the British and Germans, are much less oriented (适应) to eyeball to eyeball contact than, say, the French and Arabs. | ||||
