GRE官方题库原题153

The data from a survey of high school math and science teachers show that in the district of Sanlee many of these teachers reported assigning daily homework, whereas in the district of Marlee, most science and math teachers reported assigning homework no more than two or three days per week. Despite receiving less frequent homework assignments, Marlee students earn better grades overall and are less likely to be required to repeat a year of school than are students in Sanlee. These results call into question the usefulness of frequent homework assignments. Most likely the Marlee students have more time to concentrate on individual assignments than do the Sanlee students who have homework every day. Therefore teachers in our high schools should assign homework no more than twice a week.

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.

题目翻译

Attra州的教育部建议高中学生应该每天都被布置家庭作业。然而最近一项对于全州的数学和理化高中教师的调查却对每天布置家庭作业的作用提出了疑问。在Sanlee地区，86%的教师报告说他们每周布置3-5次家庭作业，而在Marlee地区，只有少于25%的教师报告说每周布置3-5次作业。而Marlee地区的学生综合成绩更好，而且比起Sanlee的学生更不容易留级。因此，我们高中的所有教师每周布置作业都不应该超过两次。

题目分析

1. 首先，作业更少不一定是学业成绩更好的原因。可能有其他因素导致了M地区的学生成绩更好，比如M地区的老师水平高，或者是M地区的学生本身素质较高，或是M地区学生的家庭条件较好等等。

2. 即使作业少是M地孩子成绩好的原因，这一因果关系在S地也未必能成立。因为两个地区有诸多的不同，可能会导致因果关系不再成立。比如S地的学习氛围不佳，如果不是那么多作业，孩子们就会学会赌博吸毒等，从而学坏。

3. 即使这个建议能够提高孩子们的成绩，这个建议也可能有负面影响和必要性的问题。比如减少作业量可能会让学生轻视学习;或者是可能有其他更好的方案来达到相同的效果，如引进能力更强的一批教师等。
