18.The growing popularity of computer-based activities was widely expected to result in a decline in television viewing,since it had been assuemd that people lack sufficient free time to maintain current television-viewing levels while spending incresasing amounts of free time on the computer.That assumtion,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 sprent 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 wathcing television is declining among people who reprot 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. 该题选择D为什么不对呢。 正确E。我第一眼看到结尾at work 就把这个选项剔除了。觉得是无关的。怎么就变成答案了。 牛牛们帮帮我丫 |
