【请教】GWD-T-3-Q13

T-3-Q13.             E

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 these 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 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.

个人倾向于B，原文说用新药比用旧药reinfection的几率要小，B项说新药不比旧药贵，排除了新旧比较的一个方面，strenghten;打个比方，我想买宝马，不买桑塔纳，因为宝马性能好，另一个人跟我说，两者的保修期一样长，者从侧面加强了我买宝马的信念，既然保修期一样，宝马性能好，我当然还坚持原来的主意啦。

而E说most patients feel fully recovered after taking the drug for three days.

只是病人自己feel fully recovered,到底会不会reinfected,不知道，因此不能加强原文！

 个人浅见，请各路大侠指教！！！

谢谢！！

结论是，新药比旧药的感染率低，不是新药比就要好卖。价格高不高，能决定疗效么？如你所说，宝马的价格高不高，能决定他的性能好不好么？

E的feel确实是个问题。所以还是用排除法比较好。

原题中，

因为，a new antibiotic 只需要3天疗程。而旧药需要7天。

所以，新药比就要产生在感染的几率低。

答案：不管新旧，3天后病人都会感到明显好转。

也就是说，3天后新药的疗程期满，病人明显好转，也就完成了疗程，复发可能基本不存在。而旧药需要7天，3天后仍存在复发的可能。

下次发贴，受累调大字号，造福所有人。谢谢

我认为E)中的feel不是问题反正是精华所在也是他成为正确答案的真正原因。他在强调在什么情况下病人会自己停止用药 --- 当然是在自己感觉病已经好的情况下，而由于这种错觉而停止用药对于用旧药的人来说后果比较严重。

其他同xfi883的分析过程就不重复了。
