天山3-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.
看到CD不錯的解釋轉貼過來
我覺得這麽解釋可能會好理解一些: 題目的意思是說一些病人在3天以內就停止服藥,而療程是7天,所以復發的情況很普遍,而新藥療程是3天。 而選項E,most patients feel fully recovered after taking the drug for three days 不論新藥舊藥,病人都覺得3天以後病就全好了 可能很多人包括我自己,開始都在想,題目說的是舊藥7天療效,E選項卻說不論新藥舊藥都能3天就好,不是胡扯麽?我思考了半天才想明白E選項的真正語氣和企圖,關鍵就在這一句most patients feel fully recovered ,其中的含義應該是,很多病人吃了3天藥都覺得自己病好了,但這只是他們覺得,但是病是不是真的好了就難說了。換句話說,就是因爲有E選項中描述的這種心�――大多數病人覺得自己吃藥3天病就好的這種想法,才導致了大部分人都是只吃3天藥,這�的重點是說明大部分人都只堅持吃3天藥。這樣與題幹中爲什麽復發情況很普遍就一致,因爲7天療效吃3天當然不行。同時,也排除了“很多人只吃1、2天藥”的可能,因爲這種可能也是weaken新藥來的。比如F選項,大多數病人只吃1天藥,就weaken新藥了,還是治不好。 然後,我們拿著“病人有吃3天藥的習慣”的這個條件再來看就很明顯了,大部分人都吃3天藥,吃新藥舊藥的結果就大大不同,吃新藥的人病就可以好(療程夠了),吃舊藥就很可能不好(療程不夠)。是新藥的出現,讓病人只吃3天藥病就好的理想變成現實。所以,能夠加強結論吃新藥病好的人多於吃舊藥的,吃新藥不復發的人少。 不知小弟這樣理解是否合適
