单选题
Proper street behavior in the United States requires
a nice balance of attention and inattention. You are supposed to look at
a{{U}} {{U}} 1 {{/U}} {{/U}}just enough to show that you
are{{U}} {{U}} 2 {{/U}} {{/U}}of his presence. If you look too
little, you appear proud,{{U}} {{U}} 3 {{/U}} {{/U}}much and you
are curious. Usually what happens is that people{{U}} {{U}} 4
{{/U}} {{/U}}each other until they are about eight feet{{U}} {{U}}
5 {{/U}} {{/U}}, at which point both cast down their eyes. Sociologist
Erring Goffman{{U}} {{U}} 6 {{/U}} {{/U}}this as "a king of
dimming of lights". Much of eye behavior is so{{U}}
{{U}} 7 {{/U}} {{/U}}that we react to it only on the intuitive
level. The next time you have a{{U}} {{U}} 8 {{/U}} {{/U}}with
someone makes you feel liked, notice what he does with his eyes.{{U}}
{{U}} 9 {{/U}} {{/U}}are he looks at you more often than is usual
with{{U}} {{U}} 10 {{/U}} {{/U}}a little longer than the normal.
You interpret this as a sign -- a polite one --{{U}} {{U}} 11
{{/U}} {{/U}}he is interested in you as a person{{U}} {{U}} 12
{{/U}} {{/U}}than just in the topic of conversation. Probably you also feel
that he is both{{U}} {{U}} 13 {{/U}} {{/U}}and
sincere. All this has been demonstrated in elaborate{{U}}
{{U}} 14 {{/U}} {{/U}}. Subjects sit and talk in the psychologist's
laboratory,{{U}} {{U}} 15 {{/U}} {{/U}}of the fact that their

{{/U}} {{/U}}were induced to cheat while performing a task, then were{{U}}

"shifty eyes" -- to use the mystery writers' stock phrase -- can actually be a
tip-off to an attempt to deceive or to feelings of guilt.
【答案解析】根据句意，空格中应填入一个表示“可能性”的词，Possibilities“可能性”，但常以单数的形式出现在以下句型中：There is possibility that...，不能用于Possibilities are...；Opportunities“机会”，Expectations“期望，预望”，两者从意思上均不符合句意；Chances除表示“机会”外，还可以表示“可能性”，且可用于以下句型There is a/the chance that...和Chances are...。因此答案为A。
单选题
A. glances
B. touches
C. talks
D. sights
【正确答案】
A
【答案解析】本段讨论的是眼睛的微妙动作。由上文notice what he does with his eyes可推断，空格中不可能填入touches“触摸”；sighs“视力，视觉”；空格所在的结构是对句子中“看”这一动作的进一步说明，因此talks也不恰当，而应选择glances“匆匆看”。整个句子的意思是“他看你的次数很可能比通常时候多，扫视你的时间也比正常时候长。”
【答案解析】由上文he looks at you more often than is usual with glances a little longer than he normal．可推断，对方是对你而不是对谈话的主题感兴趣，因此答案应选：rather than“而不是”，其他选项other than“除了”，better than“比…好”和less than“比…少”，均与上文不符合。
