天山－９－１８

The growing popularity of computer-based activities was widely expected to result in a

decline in television viewing, since it had been assumed that people lack sufficient free

time to maintain current television-viewing levels while spending increasing amounts of

free time on the computer. That assumption, however, is evidently false: in a recent mail

survey concerning media use, a very large majority of respondents who report increasing

time spent per week using computers report no charge in time spent watching television.

Which of the following would it be most useful to determine in order to evaluate the

argument?

A. Whether a large majority of the survey respondents reported watching television

regularly

B. Whether the amount of time spent watching television is declining among people

who report that they rarely or never use computers

C. Whether the type of television programs a person watches tends to change as the

amount of time spent per week using computers increases

D. Whether a large majority of the computer owners in the survey reported spending

increasing amounts of time per week using computers

E. Whether the survey respondents reports of time spent using computers included

time spent using computers at work

我不明白为什么选Ｅ

谢谢ＮＮ

注意原文里的这句话

assumed that people lack sufficient free

time to maintain current television-viewing levels while spending increasing amounts of

free time on the computer.

说得很清楚是free time， 呵呵，所以当然是要把工作中用电脑的时间给排除出去咯

说得很清楚是free time， 呵呵，所以当然是要把工作中用电脑的时间给排除出去咯

表面看上去， 有道理！

但是仔细想想， 是不是把工作中用电脑的时间排除并不影响这个survey的准确性和有效性，

survey结果说是不减少看电视的时间， 如果算上工作用电脑的时间都不影响，减去工作时间结果也是不会减少看电视的时间。所以E无关。

我认为是A. A 说明survey有片面性，从局部推总体，所以无效。

我的想法有问题吗？

我觉得A.E都有漏洞,

A中的regularly限制的太死了, 被调查者不一顶要时常看电视才能有代表性把.

E中的include只说了包含, 那也有可能工作中和业余时间用电脑的时间都增加.

但我还是偏向E, 感觉象ETS的风格....

open to discuss.

  做题时我也选了a，但事后总结时仔细想想答案确实是e，因为即使大部分被调查者看电视的时间很少也不等于不看电视，只要他看电视就会有看电视时间，因此个人的偏好－－自身看电视时间多少并不能影响原题的结论，原题只是是说看电视的时间，所以排除a，这个选项干扰性极强！

free time/time per week，题干中的survey偷换概念，所以E是应该明确的，才能判断SURVEY的作用。

一开始选A是因为惯性思维，一看题目大概意思，就觉得应该从推论逻辑错误入手，可能并不是因为电脑时间增多而电视时间减少阿，可能因为他们本来电视就看得少或者本来就不看电视...但regularly这词儿太不明确了...

E更明显一些...ETS好狡诈！！

survey concerning media use, a very large majority of respondents who report increasing

time spent per week using computers report no charge in time spent watching television.

Which of the following would it be most useful to determine in order to evaluate the

argument?

We must pick E.  Because we want to eliminate the people who 'increase time spend on computer' by using computer at work.  Because they would not be the population that the survey seeks to target.  We want the people who increase time on computer at home.  

模糊啊...

nn现身

晕啊晕！

谁能把最后一句解释一下？

time spent per week using computers report no charge in time spent watching television
