argument76

【题目】The following appeared as part of an article in a health and beauty magazine.
"A group of volunteers participated in a study of consumer responses to the new Luxess face cream. Every morning for a month, they washed their faces with mild soap and then applied Luxess. At the end of that month, most volunteers reported a marked improvement in the way their skin looked and felt. Thus it appears that Luxess is truly effective in improving the condition of facial skin."

感觉里面内容太少，一共也找不出几点额。。。求大家说下看法及提纲。。

应该要攻击的，这个题信息太少了。。。

1. Luxess 是否有效。没有对比组，没有排除mild soap的作用，没有排除心理作用。

2. Luxess 有效的话是不是专对这些人起作用。没有数量、特征、之前脸部皮肤情况

3. Luxess 有效性。自我感觉太主观，每个人标准不一。需要加入数量性、可操作的评判方式。

十分谢谢啦！
还是相当奇怪额。。。
再说心理因素是不是放在第三点更好啊。。。
还有一篇A35也帮忙看下，谢谢啦。。。

35.The following appeared in the summary of a study on headaches suffered by the residents of Mentia. "Salicylates are members of the same chemical family as aspirin, a medicine used to treat headaches. Although many foods are naturally rich in salicylates, for the past several decades food-processing companies have also been adding salicylates to foods as preservatives. This rise in the commercial use of salicylates has been found to correlate with a steady decline in the average number of headaches reported by participants in our twenty-year study. Recently, food-processing companies have found that salicylates can also be used as flavor additives for foods. With this new use for salicylates, we can expect a continued steady decline in the number of headaches suffered by the average citizen of Mentia." 这篇的那个has been found to correlate 能反驳么，不是一个肯定语气了，也不是推断。

“has been found to correlate”那句不是他的论据吗？这个他从二十年增加Salicylates同时头痛减少，推出以后头痛也会减少。这个推断当然要反驳啊。。。

我不是高手。。。
