单选题 Text Although "lie detectors" are widely used by governments, police departments and businesses, the results are not always accurate. Lie detectors are commonly (26) as emotion detectors, for their aim is to (27) bodily changes that contradict what a (28) says. The lie detector records changes (29) heart rate, breathing, blood pressure, and the electrical (30) of the skin. In the first part of the (31) you are electronically connected to the machine and (32) a few neutral questions ("What is your name?" etc. ). Your physical reactions serve (33) the standard for evaluating what comes (34) Then you are presented with a few (35) questions among the neutral ones ( "When did you rob the bank?" ). The idea is that if you are (36) , your body will reveal the truth, even if you try to (37) it. Your heart rate and breathing will change (38) as you respond to the questions. That is the theory, but psychologists have found that lie detectors are simply not (39) . Since most physical changes are the same across (40) emotions, lie detectors cannot tell (41) you are feeling angry, nervous or excited. (42) people may be tense and nervous (43) 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 (44) , the machine will record a "lie".

【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。
