这个讨论贴如此之长,甚至还有人引用了数学公式。。
我来阐述一下自己的观点。
条件:since the people most likely to donate are those who have donated in the past, good fund-raisers constantly try less-likely prospects in an effort to expand the donor base.
结论:laceName w:st="on">SmithtownlaceName> laceType w:st="on">UniversitylaceType>’s fund-raisers succeeded in getting donations from 80 percent of the potential donors they contacted. This success rate, exceptionally high for university fund-raisers, does not indicate that they were doing a good job.
我认为解题的重点在于:
1)紧紧扣住Argument对于good fund-raisers的定义: good fund-raisers为扩展the donor base坚持不懈地尝试less-likely prospects。(Prospects: the chances of being successful),即发掘那些尚未捐过款的人群——contacts with potential donors who had never given before。
2)看看哪个选项提供的条件可以evaluate(support or weaken)
A的条件: S were successful in their contacts as frequently as others——S校effort的成功率与他校相同。
这要作为支持选项还缺少一个Assumption,即没有说明S校是否有constantly try the effort.
即便大家有相同的成功概率,如果你try的次数相对少,拉到的new donors还是会比别人少。
本文中成功“率”不能说明任何问题,as frequently as这一说法不能有效地evaluate,既无支持,也无削弱。因此,A选项似是而无关。
再看C给出的条件: most of the donations came from previous donors。
我们不知道除了most的这些donations之外S校拉到多少new donors,即80%的success rate也不能indicate S校到底为expand the donor base做了多少canvassing effort。
–〉直接支持结论说的:This success rate does not indicate that they were doing a good job.
注意点1:结论说的“does not indicate that they were doing a good job —— 80%也不能表示S做得好。”
并不是断言S就做得不好。
注意点2:正确理解选项A中successful in their contacts as frequently as others的含义。
注意点3:不要混淆概念,文章需要evaluate的不是the size of donations或money,而是donors, 或donations.( donors makes donations ; donation是一种action,giving money or sth else)
我看几个选项是:A-无关,B-无关,D-反,E-无关
一正一反三无关,考试中若是碰到此题我会坚持选C.
