GWD6-Q15: Capuchin monkeys often rub their bodies with a certain type of millipede. Laboratory tests show that secretions from the bodies of these millipedes are rich in two chemicals that are potent mosquito repellents, and mosquitoes carry parasites that debilitate capuchins. Some scientists hypothesize that the monkeys rub their bodies with the millipedes because doing so helps protect them from mosquitoes. Which of the following, if true, provides the most support for the scientists’ hypothesis? A. A single millipede often gets passed around among several capuchins, all of whom rub their bodies with it. B. The two chemicals that repel mosquitoes also repel several other varieties of insects. C. The capuchins rarely rub their bodies with the millipedes except during the rainy season, when mosquito populations are at their peak. D. Although the capuchins eat several species of insects, they do not eat the type of millipede they use to rub their bodies. E. The two insect-repelling chemicals in the secretions of the millipedes are carcinogenic for humans but do not appear to be carcinogenic for capuchins.
太感谢了。。。。 很清楚明白了。。。 然后我还有一个问题，就是逻辑所有给出的这段话，是不是全部都要用到解题过程中去，还是要进行取舍去找条件，要是这样的话，要怎么才能取舍到有用的条件呢作者: 2008115061 时间: 2010-8-21 00:39
呵呵不客气。不是的，逻辑一般只要关注条件和结论。刚开始的背景信息不是太过重要，能看懂当然好。但记住条件和结论不要忘了 不要看到答案很支持结论 就很脑热的去选了。看清楚作者的逻辑链是怎么形成的~作者: sxf112233 时间: 2010-8-21 00:41

A. A single millipede often gets passed around among several capuchins, all of whom rub their bodies with it. 沾，先放着 B. The two chemicals that repel mosquitoes also repel several other varieties of insects. 其他的种类的虫，无关，范围错 C. The capuchins rarely rub their bodies with the millipedes except during the rainy season, when mosquito populations are at their peak. 支持 D. Although the capuchins eat several species of insects, they do not eat the type of millipede they use to rub their bodies. C吃什么，无关 E. The two insect-repelling chemicals in the secretions of the millipedes are carcinogenic for humans but do not appear to be carcinogenic for capuchins. 化学物对谁有害，无关 C明显》A,选C。作者: grubesure 时间: 2010-8-21 18:04
妹儿，杂我以上就看到你这帖子哦....作者: 云南 时间: 2010-8-21 18:41
我也是逻辑不好，老美的思维很紧凑的，我的思维就太发散了。总之，一定要结合文章的信息选答案，没提到的必错，除非是用他因削弱。GWD的逻辑有的比较绕，而且思考方式和咱们都不太一样。不过lawyer的精华帖子还是挺有帮助的，楼主可以参考下作者: Hamburger530 时间: 2012-4-13 10:32
its not about the millipede, its about the mosquitoes作者: richardliu6 时间: 2013-7-31 20:42
我也选的c，可为什么有人说选d呢？http://forum.chasedream.com/foru ... ;highlight=GWD6-Q15
