Q13:

The traditional treatment of strep infections has been a seven-day course of antibiotics, either penicillin or erythromycin.  However, since many patients stop taking those drugs within three days, reinfection is common in cases where those drugs are prescribed.  A new antibiotic requires only a three-day course of treatment.  Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed.

Which of the following, if true, most strengthens the argument?

A.  Some of the people who are allergic to penicillin are likely to be allergic to the new antibiotic.

B.   A course of treatment with the new antibiotic costs about the same as a course of treatment with either penicillin or erythromycin.

C.   The new antibiotic has been shown to be effective in eradicating bacterial infections other than strep.

D.  Some physicians have already begun to prescribe the new antibiotic instead of penicillin or erythromycin for the treatment of some strep infections.

E.   Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days.

我觉得B/D都像，可没想到给出的答案是E，我想想也有道理；但没办法排除B/D

你觉得呢？

原文结论：Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed

就是说新药好，管用，灵光。

问题：如何加强结论。

B. 新旧药价格花销差不多。 和结论新药的效果好无关，排除。

D. 一些大夫已经开始给病人开此新药了。  和结论新药的效果好无关，排除。

E. 三天肯定病好。  搞定，新药只工作3天。加强。

这题的陷阱出得很妙！

结论是： Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed.

（B）（D）讨论的是措施是否可行，而原文的结论是：如措施实可施(in cases where new antibiotic is prescribed)，那么实施之后效果如何。

不知我的理解是否到点子上。open to further discussions.

正是正是

我问过的37题D选项，也是这样的。不能只关注方案是否可行来做加强。

看来，偶要加强“加强题”！

1。方法可不可行的概念很含糊，很泛，难以界定，所以很容易被TRICK，建议慎用，我是从来不用。

2。B错的原因同joe11兄。D错的原因是结论是比较病人有吃新药的情况，所以医生没开新药从而病人没吃新药的情况不在结论讨论范围。其实该题用排除法很容易排除剩下E。

3。E的支持较复杂。原文说旧药疗程7天，有些病人才吃3天，所以reinfection较普遍（这句话要表达的意思reinfection是没完成疗期之故），新药疗程只要3天（言下之意吃完3天药，reinfection就少，加强不需要充分性，所以这点意思不需要明确从原文说出）。得出结论说吃旧药reinfection比吃新药普遍。E说不管吃旧药新药，多数病人吃三天就觉得好了。言下之意就是多数吃三天就不吃啦，这样就导致结论情况的出现，所以加强结论。

经Lawyer兄这么一说，我好像明白了偶是怎么做错的了，如下：

E.   Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days.

偶在做这道题之前，一直把加强与假设两种类型的题混同了。

偶在看到结论的时候，没有看到than in cases where either penicillin or erythromycin is prescribed这个内容，只关注了reinfection will probably be less common 。于是心中想着：reinfection减少的前提一定是用新药的人多了，那么满足这样的前提的，也就是D了，后来看到B，发现 “B非”会导致  reinfection will probably be less common 错，所以觉得B也像。至于E嘛，看了看，也觉得可以。。。

综上：这道题做错的原因有两个：

1）没有把结论看完全；

2）对假设与加强题的做法不敏感。

感谢各位。

袄觉得最重要是题目再问什么？

说实话，﹙E﹚实在有点令人难以接受，先看题目在问什么，下面是最后一句话。
Therefore, reinfection will probably be less common in cases where the new antibiotic is prescribed than in cases where either penicillin or erythromycin is prescribed.

Which of the following, if true, most strengthens the argument?

题目最后一句话提出了比较性，说是新药比旧药﹙penicillin or erythromycin﹚会有比较少的reinfection。

看一下选项﹙E﹚，

E. Regardless of whether they take a traditional antibiotic or the new one, most patients feel fully recovered after taking the drug for three days.
不论新药或旧药，大部分的病人会在3天左右完全恢复，选项﹙E﹚不但weaken题目的前提﹙题目说若吃旧药3天就停止容易reinfection﹚，而且也证实了新药和旧药大约3天内就可使大部分病人恢复，从而也weaken了题目所说的新药比旧药﹙penicillin or erythromycin﹚会有比较少的reinfection

请问C为什么不对？

而E阐述的是不论新药或旧药，我一来就把它否了。

错的太多了！
