问题 A small dose of widely used tranquilizer allows people to lie during lie detector tests without being discovered. The stress responses that lie detector tests measure can be inhibited by the drug without noticeable side effects. One of the implications of this fact is that the drug can also be effective in reducing stress in everyday situations. An assumption of the passage is that
选项 A、tranquilizers are always an effective treatment for stress.
B、the inhibition of stress responses increases subjective stress.
C、stress as measured by a lie detector is similar to everyday stress.
D、persons who lie during a lie detector test always display signs of stress.
E、it is not desirable to reduce stress in everyday situations.
答案 C
解析 本题是由一个事实“镇静剂能抑制测谎仪检测的压力反应”，而得出one of the implications ofthe fact：“镇静药也能缓解日常情况下的压力”。虽然本题是由一个事实来进行推理，但是它是把这样一个事实类推至“日常生活情况下的压力”，我们把这个事实称为A，类推(由此及彼)称为B，那么一般推理暗含的假设为测谎仪测量的压力与日常生活中的压力类似，而(C)刚好与之吻合，把A与B之间的跳跃连了起来，所以(C)正确。(A)易误选，但(A)只能是一个支持，支持关键就在always上，我们可以取非验证。如果镇静药在减轻压力方面并不总是有效的，但只要在减轻日常情况下的压力与测谎仪下的压力方面有效，上述推理的结论“镇静剂也能缓减日常情况下的压力”仍然成立，所以(A)必然不是假设。但是当把(A)中的always去掉之后，(A)便可以作为一个假设。(B)、(D)、(E)中均出现了段落推理中没有出现的新概念，因此都不正确。
