GRE作文改革后对argument写作所造成的变化

　　下面是旧GRE时代一位同学的习作。请大家忽略一些语言/逻辑方面的小问题，关注的是写作角度和模式化语言：

　　In this editorial in a wildlife journal, the author attributes the decline in arctic deer population to the global warming which makes deer unable to follow their migration patterns across the frozen sea. To substantiate his hypothesis, reports from local hunter are cited as an evidence to prove the decline of deer population. Quite convincing though it may appear to be at first glance, the authors argument suffers from several logical flaws which render his conclusion highly dubious.

　　Firstly, he alleges there has been a decrease of deer population merely based on the report from local hunter, which is questionable since local hunter cannot cover the whole arctic region, and thus be unable to provide accurate data concerning deer population. It is very likely that deer have intentionally avoided direct contact with hunters in order to survive the hunting. In such a case, hunters would have naturally observed less deer while the whole population remains the same or even rise. Hence, with inadequate information offered by the author, its unclear whether the deer population has decreased or not.

　　Secondly, the recent trend of global warming cannot necessarily mean there lies an increase of temperature in arctic area. Since Earths climate system is highly intricate, there could be huge difference in separate regions where one suffers from heat waves while the other witnesses an even colder climate. Without any direct temperature data inside arctic region, we could not say the temperature of arctic has actually increased.
