31. Society should make efforts to save endangered species only if the potential extinction of those species is the result of human activities.
Write a response in which you discuss the extent to which you agree or disagree with the statement and explain your reasoning for the position you take. In developing and supporting your position, you should consider ways in which the statement might or might not hold true and explain how these considerations shape your position.
点评：此题在Issue考试中为top 5的高频题，与63跟67题本质上是相同的。观点的评价其实应该不难，我简单的说下。
1>诚然，过去很多的动物都是因为自身不能够适应自然条件或者竞争法则而灭绝的。
The first is essentially the Darwinian argument that extinction results from the inexorable process of so-called "natural selection" in which stronger species survive while weaker ones do not.
然而，professional agency of species protection公布的数据表明，目前动物因为人类灭绝的数量是自然灭绝的 100 倍。人类对环境的污染导致很多生物不能够适应剧变的环境而灭亡;人类的大量开发土地和 deforest 导致生物的生存空间越来越小。人类正在成为 leading killer，所以，我们有责任去保护那些濒临灭绝的动物。
2>保护那些濒临灭绝的动物对我们的生态系统有好处。
3>一个国家的人类财力是有限的，不能一味的全用来保护濒危物种。保护濒危物种与社会的进步，经济的发展不应该对立。

82.Colleges and universities should require their students to spend at least one semester studying in a foreign country.
学院或大学应该要求学生在国外至少留学一个学期。
Write a response in which you discuss the extent to which you agree or disagree with the recommendation and explain your reasoning for the position you take. In developing and supporting your position, describe specific circumstances in which adopting the recommendation would or would not be advantageous and explain how these examples shape your position.
点评：此题相对高频，top20的样子，而本身难度其实很低，大家都是要出国的人，如果连这么简单的辩证分析都搞不出来那也不用混了。
1>当今出国留学已成为一股热潮，增长知识，丰富阅历，感受文化，培养独立能力。
2>没有必要人人都出国，有些专业出国给学生自身的提升带不来什么提升。
3>正确定位，选择最适合的方式。要考虑家庭负担以及自控能力;有些学生因为要适应环境，或者无法适应环境，不但没有学到预想的知识，还浪费了大好青春。
2.Argument
60/145/146/150/154/155
60.The following appeared in a letter from a firm providing investment advice to a client.
"Homes in the northeastern United States, where winters are typically cold, have traditionally used oil as their major fuel for heating. Last year that region experienced twenty days with below-average temperatures, and local weather forecasters throughout the region predict that this weather pattern will continue for several more years. Furthermore, many new homes have been built in this region during the past year. Because of these developments, we predict an increased demand for heating oil and recommend investment in Consolidated Industries, one of whose major business operations is the retail sale of home heating oil."
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.
翻译：在冬季非常寒冷的美国东北部的房屋，一直都使用传统的油料作为采暖的主要燃料。去年该地区经历了90天低于往年平均气温的严寒，并且气象预测家们预测这种天气会持续未来数年。而且，去年本地建造了很多的房屋。按此趋势，我们预测对于油料的需求将会增加. 所以我们建议对CI公司投资，该公司的主要业务之一就是家用采暖油料的零售。
点评：这是Argu中最高频的题目，没准备过绝对要打屁股!
1>90多天的冬季看似很久，可以以前的天气情况没有提，要是一般的冬季都比这个时间长的话，那么这个冬天就是暖冬了，自然油料的使用量可能就不会提高，相反还会下降，而且泛泛的指出是在零下，没有说零下多少度，要是很冷的温度只持续了一小段时间，而大多数的时间都是比零度低一点点的话，那么温度总体上还是提高的，油料也是没有用处的。
2>很多的住宅新建起来，不见得很多人都会立刻搬进去居住，可能是房子的质量不好，也可能是人们的工资负担不起那里昂贵的房价> 又或者交通不便利，环境不好等因素。
3>这个公司是零售的，而那里的人们，小区什么的都是承包给大的集团公司，他们这样的小公司可能没有市场>

62.The following appeared in a memo from the director of a large group of hospitals.
"In a laboratory study of liquid antibacterial hand soaps, a concentrated solution of UltraClean produced a 40 percent greater reduction in the bacteria population than did the liquid hand soaps currently used in our hospitals. During a subsequent test of UltraClean at our hospital in Workby, that hospital reported significantly fewer cases of patient infection than did any of the other hospitals in our group. Therefore, to prevent serious patient infections, we should supply UltraClean at all hand-washing stations throughout our hospital system."
Write a response in which you examine the stated and/or unstated assumptions of the argument. Be sure to explain how the argument depends on these assumptions and what the implications are for the argument if the assumptions prove unwarranted
翻译：再一次对于抗菌洗手液的实验研究中，UC浓缩液比我们医院目前使用的洗手液多杀40%的细菌。我们对在W的医院做的随后测试中发现，该医院上报的患者感染数量明显少于我们集团的其他医院。因此，为防止严重的患者感染，我们应该在我们的医院系统内的所有洗手站提供UC洗手液。
点评：这题也是挺热门的，难度也不大，下面是解析，大家可以稍微参考下：
1>前提不一定成立，即使用N洗手能减少感染，论者提供的论据不足以支持结论。
2>首先室验室的结果不证明在现实使用中效果一样显著，因为N有可能受到现实环境中其它化学和物理因素的影响，而使其失效。
3>论据没有说服力，关于S医院的经验。首先S医院的感染病人比其它医院少，但是与它不使用N的时候呢?如果不使用N，S医院的此类病人也少，就不能证明是N防止了病人感染。其次S医院对N的测试，但未说是如何使用，可能并不只是用于洗手液。结论：首先N是否有副作用，
4>其次，N杀死的细菌是否是能引起严重感染的，还是只是较弱的细菌。
结论：论者应进一步了解N用于洗手液在实际情况中的杀菌效果，并一步了解S医院的经验是否值得推广
3.作文总结
这次考试的作文组合大概是两个版本：Issue 31 + Argu 60 或者Issue 82 + Argu 62的组合。应该来说，GRE作文在经历了黑暗3月份的冷门迭爆之后，ETS终于脑子正常的出了回正常题，本次的作文题无论是难易度还是热门度上都可以说对于认真准备的考生而言，so easy~
