GRE作文是中国学生比较头痛的，经常准备很多时间最后还是只得到3.5。我之所以得到6分，个人认为我的文风比较淳朴扎实，有科学性，写的思路比较广(正、反、特)，字数也比较多(I800+、A700+)。
A threshold problem with the argument involves the statistical reliability of the survey. The
222
director provides no evidence that the number of respondents is statistically significant or that
the respondents were representative of auto workers in general. Lacking information about the
randomness and size of the survey's sample, the director cannc;to make a convincing
argument based on that survey.
Even if the survey's respondents are representative of the entire population of auto workers,
the argument relies on the assumption that the responses themselves are reliable. Yet the
director ignores the possibility that a young, inexperienced worker is less likely to be forthright
about the value of supervision--for fear of retaliation by that supervisor. For that matter,
younger workers might not have enough experience working without supervision to determine
when they are most productive. Lacking evidence that the respondents' reports were both
truthful and meaningful, the director cannot confidently draw and conclusions about worker
productivity from them.
Even assuming that the survey data accurately reflect the auto industry, the argument
unfairly assumes that supervision affects worker productivity similarly at PPC. Perhaps PPC
employs certain unique equipment or processes that require close worker supervision--even
for older, more experienced workers. For that matter, perhaps youth or inexperience is an
advantage in working productively at PPC, whereas in the auto industry either is a
disadvantage. In short, without accounting for possible differences between PPC and auto
manufacturers the director cannot convince me that his recommendation for PPC is sound.
The argument also assumes that older people are more experienced, and thus less likely to
benefit from supervision, than younger people. Although this assumption might gen erally be
sound, it nevertheless might not hold true for workers at PPC specifically. In other words,
despite their age many younger PPC worker might be more experienced at their jobs, and
therefore more productive without supervision, than many older PPC workers. 感谢您阅读《GRE作文范文大全（129） 》一文，出国留学网(liuxue86.com)编辑部希望本文能帮助到您。
