GRE，全称Graduate Record Examination，中文名称为美国研究生入学考试，适用于除法律与商业外的各专业。由美国教育考试服务处(Educational Testing Service，简称ETS)主办，GRE是美国、加拿大的大学各类研究生院（除管理类学院，法学院）要求申请者所必须具备的一个考试成绩，也是教授对申请者是否授予奖学金所依据的最重要的标准。 另有，Generic Routing Encapsulation（通用路由封装）也简称GRE。 A threshold problem with the argument is that it assumes that what improves memory and learning in rats will also improve memory and learning in humans. Although this is entirely possible, the argument provides no evidence to support this assumption. Without such 194 evidence the argument can be rejected out of hand. A second problem involves the fact that PEP increasingly breaks down the chemicals needed for learning and memory as humans age--as the argument points out. Yet the argument seems to daim that inhibiting PEP will be effective in improving learning and memory in young people. (The argument refers to students' "parents," implying that proposed human subjects are young people rather than adults.) Thus the effectiveness of the compounds is likely to be far less significant than it would be for older people. A third problem with the argument is that it assumes that learning and memory are the only significant factors affecting performance in school. Common sense and experience tells us this is not the case, and that a variety of other factors, such as motivation and natural ability, also play major roles. Thus the compounds might very well turn out to be largely ineffective. A final problem with the argument is that it asserts that the compounds will improve concentration, yet it makes no claim that the same compounds improved concentration in rats----only that they improved the rats' learning and memory. Thus the argument's conclusion is indefensible to this extent. In sum, the argument is weak on several grounds. To strengthen it the argument's proponent must provide clear evidence that the same compounds that improved learning and memory in rats will do so in young humans. Moreover, the argument's proponent must show that poor academic performance is due primarily to learning and memory problems, rather than to poor concentration, motivation, or other factors. 感谢您阅读《GRE作文范文大全（115） 》一文，出国留学网(liuxue86.com)编辑部希望本文能帮助到您。
