Q3: TTGWD11-Q19:
In Rubaria, excellent health care is available to virtually the entire population, whereas very few people in Terland receive adequate medical care. Yet, although the death rate for most diseases is higher in Terland than in Rubaria, the percentage of the male population that dies from prostate cancer is significantly higher in Rubaria than in Terland.
Which of the following, if true, most helps to explain the disparity between the prostate cancer death rate in Rubaria and Terland?
A.Effective treatment of prostate cancer in its early stages generally requires medical techniques available in Rubaria but not in Terland. 加强
B.Most men who have prostate cancer are older than the average life expectancy for male inhabitants of Terland.
C.Being in poor general health does not increase one’s risk of developing prostate cancer. 反对前提
D.It is possible to decrease one’s risk of getting prostate cancer by eating certain kinds of foods, and such foods are more readily available in Rubaria than in Terland.
E.Among men in Rubaria, the death rate from prostate cancer is significantly higher for those who do not take full advantage of Rubaria’s health care system than for those who do.
分析选项:
A R地能治疗P,T地不能治疗。无法解决矛盾,排除。
B 大多数有P病的男性要老于T地男性的平均寿命。在这种情况下,实际有可能得P病的人就非常少了(因为高于平均寿命,大部分人都在平均寿命左右死去了)。因此可以解释。本选项没有解释为啥R地多,但解释了为啥T地少,因此也可以为正确选项。
C 在不好的医疗条件下,不会增加得P病的概率。文章关注的是死于P病的概率,与得病没有关系。实际是无关选项。没抓住主关键点。
D 能预防P病的食物,在R地有,在T地没有。和A一样,无法解决矛盾,排除。
E 死于P病的比例在R地的人,没有很好利用R地的医疗优势。那最多就是两个地方差不多呀,因此无法解释。 (用范围的观点看,这个范围出去了,是R和T比,不是R内部比)
不知道正确答案是不是B,呵呵作者: bastencool 时间: 2011-7-18 06:34
B是答案~ 解释很强大

其实没那么复杂。。首先看题干,既然是发现the percentage of the male population出现了disparity,那么以下选项解释的中心词一定是 male,即正确选项一定要从male下手。
其次,D选项不是explain the disparity, 反而是 strengthen the disparity, 既然在这种食物在R地有在T地没有,那么更能说明R地的death rate for this disease 比T地的低才对,这样更能加深矛盾性,而不是解释矛盾性。
E选项一看限定短语.Among men in Rubaria, 这个选项无疑就是错误的,因为题干是比较两个地点的 death rate for disease, 那么解释的着手点当然是在比较这两的地点上的差异, 而.Among men in Rubaria 此限定词,就发现E选项所做的比较是在R地内部里面比较,而不是R与T在比较。作者: philipyu1025 时间: 2011-7-19 06:23
