Eye behavior, involving varieties of eye-contact, can give
subtle messages which people pick up in their daily life.
Warm looks or cold stares tell more than words can. Meeting
or failing to meet another person's eye produce a particular__1__
effect. When two American look searchingly at each other's __2__
eye, emotions are heightened and the relationship becomes
closer. However, Americans are careful about where and __3__
when to meet other's eye. In our normal conversation, each
eye-contact lasts only a few seconds before one or both
individuals look away, because the longer meeting of the eyes
is rare, and, after it happens, can generate a special kind of __4__
human-to-human awareness. For instance, by simply using his
eyes, a man can make a woman aware of him comfortably or
uncomfortably; a long and steady gaze from a policeman or judge
intimidates accursed. In the US proper street behavior requires__5__
a nice balance of attention and inattention. You are supposed to
look at a passer-by just enough to show that you are being aware __6__
of his presence. If you look too little, you appear haughty; too
much, inquisitive. Much eye behavior is such subtle that our __7__
reaction to it is largely instinctive. Besides, the codes of eye
behavior vary dramatically from one culture to other. In the __8__
Middle East, it is impolite to look at the other person all the
time during a conversation; in England, the polite listener fixes
the speaker with an inattentive stare and blinks eyes occasionally__9__
as a sign of interest and attention. In America, eye behavior
functions as a kind of conversational traffic signal control the __10__
talking pace and time, and to indicate a change of topic. If you
can understand this vital mechanism of interpersonal relations,
the basic American idiom is there.
