俺choose A,俺很挣扎,但是确实没有选择E的理由,我认为E是无关项,包不包括工作时间看电视无关紧要。我还是为A找了个理由。如果这写respondents并没有看电视的习惯,那么他们使用电脑当然不会占据看电视的时间了,在他们身上我们是找不到电脑&TV的关系的,也就是他们不representative,要使他们represeantative,那么他们一定是regularly看电视一族,这样我们才能evaluate这个survey对结论的有效性。选A吧,这样又可以少错一个了,sigh

I choose (E). Why? The key lies in "people lack sufficient free time." I have to know whether the respondents of that survey are people lack sufficient free time before making an judgement.


It is important to realize, at first, that the time after your work is a free time. For example, from 7pm to 11pm.


If (E) is right: respondents are increasingly using computer during their work. Their time spent on computer INCREASED, but after work, they use their sufficient free time to watch television. Their time spent on TV remains NO CHANGE, always 7pm to 11pm. --> this is people don't lack sufficient free time.


If (E) is no: respondents are increasingly using computer after their work. Their time spent on computer INCREASED, but they have to sacrifice some of their free time to television now, therefore the time spent on TV DECREASED. (for example, 7pm to 9pm using computer, and 9pm to 11pm watching TV) --> this is people lack sufficient free time.


Therefore, answer (E) helps us to evaluate the author's argument.

支持A,  


题中的假设说人们缺乏充足的时间看电视,结论是这个假设是不正确的,因为最近的survey中大部分的回应者反映说看电视的时间没有受到影响。


看一下A,如果大部分的回应者不是经常地看电视,这个survey根本就是无效的,因为他们本来就不怎么看电视,当然对他们没有影响。反之,survey是有效的。


看一下E,无论电脑使用时间的增加是通过什么方式,都对这个survey是否有效没有影响,根本无法得出结论。

这题是典型的偷换概念的题。


the question is about the allocation of the people's free time spend between the TV and Computer, but the survey is the increasing time spent per week using computers ,


time spent per week using computers ==free time + work time

选e 把握逻辑关键词

A和E都是想说明sample不具备代表性,只是A focus 在看电视这件事上,E focus在电脑上。E对,因为只有E成立了,这个survey才有意义。A的缺点在于not regularly并不代表看电视少于平均水平。

A其实对结论没有影响.即使这些人不regular看电视,但如果他们玩电脑的时间增加.看电视的时间还是会减少的.

这道题的关键是这个 regularly,选A的人基本上都是把它当作“经常”的意思,但它的实际意思是“有规律的”,有没有规律对时间长短没有影响,而是固定在某些点看电视,所以还是E!

regular也有经常的意思,但还是觉得e选项更直接。
