※ 引述《sunnyE (原来改不了?)》之铭言： : ※ 引述《CGHS13 (.......)》之铭言： : : The traditional treatment of step 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 prescirbed. A new antibiotic require only a three-day course of : : treatment. Therefore, reinfection will probably be less common in cases where : : the new antibiotic is prescibed than in cases where either penicillin or : : erythromycin is prescribed. : : which of the following, if true, most strength the argument? : : A Some of people who are allergic to penicillin are likely to be allergic to : : the antibiotic : : B A course of treatment with the new antibiotic costs about the same as a : : course of treatment with either penicilline or erythromycin : : C The new anitibiotic has been shown to be effective in eradicating bacterial : : infection othe than step : : D Some physicians have already begun to prescibe the new antibiotic instead of : : penicillin or erythrimycin 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 : : ANS: E : : why? : 因为原题提到traditional疗法是7天course，but病人常三天内就懒的再吃所以病复发 : 但是新药是三天course : 所以选项E可以支持题目 : 其实旧的跟新的药都是吃三天就好，只是病人觉得七天很烦，还没三天就不吃了 : 那现在新药只有三天的疗程，病人可能就比较愿意接受。(重点是他们病会好) : SO这样的疗程可能比较common 想问一下 是不是因为其实多数人都在三天内好 所以 多数人选择 只需要吃三天的新药-病就好了 ->所以新药的使用增加 ->增加了新药的使用 就降低了reinfection 所以可以strenghten new ->infection less 的结论? 那麽 D 有些医生开新药给病人吃 那不是也可以增加新药的使用->降低reinfection ? --
