Eye behavior can give subtle messages which
people pick up in their daily life. It tells more than
words can. Meeting or failing to meet another person's
eyes produce a particular effect.When two Americans __1__
look searchingly at each other's eye, emotions are __2__
heightened and the relationship becomes closer. How-
ever, Americans are careful about where and when to __3__
meet other's eye. In our normal conversation, each
eye-contract 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 __4__
a special kind of human-to-human awareness. For instance,
by simple 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 accused. __5__
In the U.S., proper street behavior requires 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 of his presence. If you look too little, __6__
you appear haughty; too much, inquisitive. Much eye
behavior is such subtle that our reaction to it is __7__
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 __9__
stare and blinks eye occasionally 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.

参考答案及解析:
1.把produce改为produces
本句中两个主语meeting和failing to meet another person's eye 用or连接，这时谓语动词应该采取就近原则，与最相邻的主语一致。

2.把at改为into
此处的动作应该是look into（注视），而不是一般的“看”（look at）。

3.把where改为how
上下文介绍的是目光交流的方式方法。

4.把after改为when/if

5.在accused前面加上the
intimidate（胁迫）是一个及物动词，后面不能只接形容词，此处应该加上定冠词，与accused构成名词短语，表示一类人，即“被告”。本句的意思是：
例如，只要运用目光，男人就可以让女人很自在或者不舒服地感觉到他的存在；而警察或法官的长时间的注视可以威吓被告。

6.删除being

7.把such改为so

8.把other改为another
表示不定指代的“一个或者另一个”应该用one and/or another。

9.把inattentive改为attentive

10.在control前面加上to
control the talking pace and time 应该和to indicate a change of topic并列，作为conversational traffic signal 的定语，也要用动词不定式。
