Text{{/B}} Although "lie detectors"
are widely used by governments, police departments and businesses, the results
are not always accurate. Lie detectors are commonly {{U}}(26)
{{/U}} as emotion detectors, for their aim is to {{U}}(27) {{/U}}
bodily changes that contradict what a {{U}}(28) {{/U}} says. The lie
detector records changes {{U}}(29) {{/U}} heart rate, breathing, blood
pressure, and the electrical {{U}}(30) {{/U}} of the skin. In the first
part of the {{U}}(31) {{/U}} you are electronically connected to the
machine and {{U}}(32) {{/U}} a few neutral questions ("What is your
name?" etc. ). Your physical reactions serve {{U}}(33) {{/U}} the
standard for evaluating what comes {{U}}(34) {{/U}} Then you are
presented with a few {{U}}(35) {{/U}} questions among the neutral ones (
"When did you rob the bank?" ). The idea is that if you are {{U}}(36)
{{/U}}, your body will reveal the truth, even if you try to {{U}}(37)
{{/U}} it. Your heart rate and breathing will change {{U}}(38)
{{/U}} as you respond to the questions. That is the theory,
but psychologists have found that lie detectors are simply not {{U}}(39)
{{/U}}. Since most physical changes are the same across {{U}}(40)
{{/U}} emotions, lie detectors cannot tell {{U}}(41) {{/U}} you are
feeling angry, nervous or excited. {{U}}(42) {{/U}} people may be tense
and nervous {{U}}(43) {{/U}} the whole procedure. They may react
physiologically to a certain word ( "bank" ) not because they robbed it, but
because they recently used a bad check. In either {{U}}(44) {{/U}}, the
machine will record a "lie". On the other hand, some practiced
liars can lie {{U}}(45) {{/U}} hesitation, so the reverse mistake is
also common.
【正确答案】
A
【答案解析】[精解] 本题考查词语搭配。be known as意为“以……知名，被认为是……”，是固定搭配。design意为“设计，计划”；fix意为“修理，固定装置”；produce意为“生产，制造”，都无法与as搭配。故选A。
【答案解析】[精解] 本题考查动词的用法。通过上下文推测句意为“你被问到几个一般性的问题”。这里“…you are…______a few neutral questions…”是被动用法，没有介词，所以要填一个及物动词。investigate调查，用法是investigate sth．；raise提出，其用法是raise sth.，若用在这里应是raise a question to sb.，不能用sb．was raised a question；question询问，用法是question sb./sth.；ask是及物动词，可以用被动，常说ask sb．a question，变为被动就是sb．is asked sth.。故答案选B。
【答案解析】[精解] 此题考查限定词的用法。根据常识我们可以知道，不可能所有的情绪都表现为相同的生理变化，故排除B、C项。 other emotions意为“其他情绪”，结合全句看，就是“对于其他情绪来说，大多数人的生理变化都是相同的”，这与全句句意不符。根据文意和常识判断，应是“对于一些情绪来说，大多数人的生理变化都是相同的”。故选D。
【答案解析】[精解] 本题考查短语的固定搭配。fact一般和in搭配，中间不存在冠词，in fact意为“事实上”；condition一般和under搭配，如under some condition；chance常和by搭配，中间不加冠词，by chance意为“碰巧地”；case和in搭配，in case意思是“万一”，中间有冠词时，如in either case，意为“在(两种情况中)任意一种情况下”，其他搭配还有in such a case/in the case of sth．/in some cases/in most cases为“在……情况下”。所以答案选D。
