也許有人說arguement有什么難寫的，不就是找邏輯錯誤么？那么多錯誤，隨便找3個就ok了，簡單的很。但是，我得告訴大家，arguement不單單是要你找邏輯錯誤，內在的要求是你自己的文章也要很具有邏輯性。

       什么叫很具有邏輯性？那就是你文章的組織、你段與段之間的關系，不能拉出來什么就是什么；什么邏輯問題能說的多就先說什么；什么邏輯來不及說或者說不清楚，就草草結束。邏輯錯誤應該是從大到小排列，而不是簡單的先到先排。

       Arguement 51: The following appeared in a medical newsletter.

       "Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain. This hypothesis has now been proved by preliminary results of a study of two groups of patients. The first group of patients, all being treated for muscle injuries by Dr. Newland, a doctor who specializes in sports medicine, took antibiotics regularly throughout their treatment. Their recuperation time was, on average, 40 percent quicker than typically expected. Patients in the second group, all being treated by Dr. Alton, a general physician, were given sugar pills, although the patients believed they were taking antibiotics. Their average recuperation time was not significantly reduced. Therefore, all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment."

       先看我同學是怎么寫的。他的3段攻擊大概是這樣的：

       1. 2個醫生背景不同；

       2. 2個實驗組的具體情況信息實在太少，不足以判斷；

       3. 并不一定所有的病人都會發生2次感染。

       想來他的思路具有一些普遍性。現在來看我說。

       要寫好arguement，首先就是要學會讀題目。

       怎么讀題目？不是單單找邏輯錯誤就完了的。你更要分析題目句子和句子間的邏輯關系。也許有的人此刻會笑，心說，“哪個模版上不說，‘arguer所說的結論是什么，他的論據是什么……’，有誰會分不清楚？” 雖然誰都知道，但是你有沒有真正想過這里面的內在含義？

       這個題目，我會分成3塊。

       第一是前提：Doctors have long suspected that secondary infections may keep some patients from healing quickly after severe muscle strain.

       第二是結論：Therefore, all patients who are diagnosed with muscle strain would be well advised to take antibiotics as part of their treatment.

       剩下來的都是論據。

       但是請分清楚這些都是誰的論據，他們都是用來證明“This hypothesis has now been proved by preliminary results of a study of two groups of patients”的。換言之，就是前提的論據。

       簡單說來，就是作者的話可以這樣復述：“因為【前提】的存在，所以我的【結論】是……。那為什么說這個【前提】是正確的呢？因為【論據】。”

       那現在我們來分析，這3者間的邏輯關系。前提和結論，可以說是一個因果關系（至少作者想體現出一種因果關系）；論據和前提，也可以說是一個因果關系，因為這里的論據是用來證明前提的。

       但是，究竟哪個邏輯關系是主關系呢？顯然應該是前提和結論的因果關系。如果你承認這點，那么就應該在你的第一攻擊點，首先考慮攻擊這個關系。反過來說，如果你第一段攻擊了那2組病人的實驗，那你就是主次沒分清楚。
