2.跳蚤是害虫 Lyme disease is caused by a bacterium transmitted to humans by deerticks. Generally deer ticks pick up the bacterium while in the larval stagefrom feeding on infected white footed mice. However, certain other species onwhich the larvae feed do not harbor the bacterium. Therefore, if the populationof these other species were increased, the number of ticks acquiring thebacterium and hence the number of people contracting Lyme disease—would likelydecline. Which of the following, if true, most strengthens the argument? A. Ticks do not suffer any adverse consequences from carrying thebacterium that causes Lyme disease in humans. B. There are no known cases of a human’s contracting Lyme diseasethrough contact with white-footed mice. C. A deer tick feeds only once while in the larval stage. D. A single host animal can be the source of bacteria for many ticklarvae. E. None of the other species on which deer tick larvae feed harborother bacteria that ticks transmit to humans.
F:F:莱姆病是一种细菌感染性疾病,通过鹿蜱传染给人类。鹿蜱在幼体阶段用白足鼠喂养时沾染上细菌。而其他用来喂养的种群没有携带这种病毒。 P:如果其他种群的数量上升了 C:带有这种病毒的蜱和因此感染莱姆病的人的数量就会下降 Q:问加强 思路:直接加强其他用来喂养的种群数量上升与带病毒的蜱和感染人数的下降;排除它因 选项:A项,无关;B项,无法加强;C项,只进食一次,说明数量受到这个白足鼠的限制;D项,被多只幼体吃,不会减少以白足鼠为食的幼体的,削弱;E项,无法加强;

P:十八世纪中期第一次犯罪的人突然上升,人口也上升,但增长速度慢 C:不能说人们变得暴力了 Q:问原因 思路:断开初次犯罪率上升与人变得暴力的联系 方向:法律进行了修改,变得更严格了所以犯罪率上升了 |
