The growing popularity of computer-based activities was widely predicted to result in a corresponding decline in television viewing.Recent studies have found that, in the United States , people who own computers watch, on average, significantly less television than people who do not own computers.In itself, however, this finding does very little to show that computer use tends to reduce television viewing time, since __________.
A. many people who watch little or no television do not own a computer
B. even though most computer owners in the United States watch significantly less television than the national average, some computer owners watch far more television than the national average
C. computer owners in the United States predominantly belong to demographic groups that have long been known to spend less time watching television than the population as a whole does D. many computer owners in the United States have enough leisure time that spending significant amounts of time on the computer still leaves ample time for watching television
E. many people use their computers primarily for tasks such as correspondence that can be done more rapidly on the computer, and doing so leaves more leisure time for watching television

E是加强了。A是完全和论题不在一个点上。论题说的是有电脑和看电视时间的事情，A都没沾边吧作者: xulinran 时间: 2012-8-19 09:25
嘿嘿~~E不是说会给看电视留下更多空闲时间么？我怎么觉得也是削弱呢？作者: 瓦利哥 时间: 2012-8-31 00:16
e说明了使用电脑可能增加看电视的时间，但是题目问的是“this finding does very little to show...”，请注意，这里说的是“this finding”，e的内容跟this finding毫无关系。
求指教！
