------摘要------
大纲：
1。学生表现差和老师辞职多不一定是日光减少的原因
2。TVS的学生成绩提高也不一定是用了灯泡提高的，TVS 与SJHS情况不一定相同
3。还有其他的可能提高：用其他牌子的灯泡、修订学校规定等

------题目------
The following appeared in a memo from the Principal of Sherwood Junior High School.
'It appears that the lighting in Sherwood High's classrooms, which have large windows but minimal overhead light sources, is impairing student academic performance and teacher morale. Records show that during December and January, the two months with the fewest hours of daylight, attendance rates fall, average daily class participation drops, and grades decline. Teacher resignations are also highest during these months. According to a study of Tundra Vocational School, which experiences entire seasons with little daylight, students' grade point averages increased when Day Glow light bulbs, which mimic sunlight, were installed in classrooms. This study suggests that Sherwood can improve students' academic performance and teachers' morale by using Day Glow light bulbs in winter.'
------正文------
The author of this argument seems to be a little hasty when offering the suggestion that Sherwood Junior High School(SJHS) should use Day Glow light bulbs in winter, since the several facts he cites does not well substantiate his suggestion.

To begin with, the author assumes that students' worse academic performance and high rate of teacher resignation are caused by the lack of light.  However, the author provides no clear evidence that there is causal relationship between them.  According to the records, during December and January student academic performance deteriorates and teacher resignations are highest, which can be result from various reasons.  The low attendance rates and average daily class participation can be attributed to the cold weather, or holidays.  People tend to be reluctant to get up early in morning in cold days, and students may be too excited about the coming Christmas and New Year to skip classes to shopping or parties.  With this fall of attendance rates and average daily class participation, the decline of grades is no surprising.  And it is entirely possible that teachers are so annoyed by the students' unbearably bad academic performance that they resign to express their anger, or some teachers may wish to have a raise of pay by handing in a resignation.  The fewest hours of daylight as the author mentions, may be just a coincidence rather than a cause.  Therefore, the few hours of daylight may have little or even no influence on the student academic performance and teacher resignations.

Similarly, the increase of average students' grade point after installing Day Glow light bulbs in Tundra Vocational School (TVS) does indicate correlation between the two, but it is not necessarily the causal relationship.  Moreover, the author fails to supply evidence to show that installing Day Glow light bulbs will have the same effect in SJHS.  The situation is totally different.  While students in TVS experience entire seasons with little daylight, students in SJHS may enjoy plenty of daylight in most days of a year.  Unless the author can provide further information to show that Day Glow light bulbs would actually have similar effect on SJHS as TVS, the suggestion is unreasonable.

Even assuming that there is causality between the lack of daylight and student academic performance and teacher morale, and that Day Glow light bulbs can improve student academic performance and teacher morale, the author fails to rule out other possibilities.  Perhaps the Day Glow light bulbs are especially designed for tundra, and other bland of light bulbs would be more suitable for students in SJHS.  Or revising the school rules, such as relate the students' grade to their attendance would actually be more effective.  With these alternatives, it is not justified to simply suggest that using Day Glow light bulbs would be the best way.

To sum up, although students' academic performance and teachers' morale in SJHS are worse in winter, and students in TVS improved their average grade point after installing the Day Glow light bulbs, it might not be the best way to simply using the Day Glow light bulbs to improve.
