经Lawyer兄这么一说,我好像明白了偶是怎么做错的了,如下: 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. 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。 |
