gre改革后新版gre写作新题库里的作文方面的一个重要变化是有了指导语。而指导语的作用是有助于我们的逻辑性写作，以下是新版gre写作新题库内有关argument91的写作部分：

　　题目：

　　Three years ago, because of flooding at the Western Palean Wildlife Preserve, 100 lions and 100 western gazelles were moved to the East Palean Preserve, an area that is home to most of the same species that are found in the western preserve, though in larger numbers, and to the eastern gazelle, a close relative of the western gazelle. The only difference in climate is that the eastern preserve typically has slightly less rainfall. Unfortunately, after three years in the eastern preserve, the imported western gazelle population has been virtually eliminated. Since the slight reduction in rainfall cannot be the cause of the virtual elimination of western gazelle, their disappearance must have been caused by the larger number of predators in the eastern preserve.

　　Write a response in which you discuss what specific evidence is needed to evaluate the argument and explain how the evidence would weaken or strengthen the argument.

　　中文翻译：

　　3年前，由于P西部野生动物保护区的洪水，100只狮子和100只西部羚羊被转移到了东部，这里也是很多与西部物种属相同种族的物种的家，尽管数量更大，同时也是西部羚羊的近亲-东部羚羊的家。气候上唯一的区别就是东部雨量微少一些。不幸的是，3年后，东部保护区的外来西部羚羊几乎绝迹。因为雨量的微小差别不可能是导致西部羚羊灭绝的原因，其灭绝原因一定是因为东部保护区内大量的食肉动物的存在。

　　写一篇回应，讨论还需要何种具体的证据才能更好的评估上面的论证，并解释这个证据是如何强化/削弱这篇文章的论证的。

　　此上就是新版gre写作新题库 argument91的内容从今天起小编就给大家连续提供新版gre写作新题库argument部分的内容。希望大家能够在练习中提高自己的写作水平。
