本月RC JJ 67- 也是GWD一篇. 求统一答案

jandjshi

最后一段的例子很重要因为是用来证明not all chemical signals transmitted via the VNO qualify as pheromones.

garter snakes detect a chemical signal from earthworms－one of their favorite foods－via the VNO, and they use this signal to track their prey.    违反了
     some reserchers also specify  that the response to pheromones must be Unconscious
      

所以not all chemical signals transmitted via the VNO qualify as pheromones

所以Q9 答案 E

黄色部分是违反了a basic definition of pheromones as chemicals released by one individual of a species which, when detected by another individual of the same species.

conscious还是unconscious不知道.

嘻嘻. jeff 这篇文章是有解释 phermone. 但是你仔细看. 整篇文章是作者构思的一个完整的逻辑题. 指不过提出问题的是他. 解题的也是他. 这才是文章的重心

是呀第一段说 phermone 是 as chemicals released by one individual of a species which, when detected by another individual of the same species.

然后 phermone 不能用作 ordant 的原因是因为 phermones 是在 VNO 中被 process

但现在说了 VNO　中的并不是　Ｐｈｅｒｍｏｎｅｓ

例证是蛇用ＶＮＯ　ｄｅｔｅｃｔ　到的东西去ｔｒａｃｋ　ｅａｒｔｈｗｏｒｍ　（ｗｈｉｃｈ　ｉｓ　ａ　ｈｉｇｈｌｙ　ｃｏｎｃｉｏｕｓ　ｂｅｈａｖｉｏｒ）

所以证明　ｐｈｅｒｍｏｎｅ　不能是　ｏｒｄａｎｔ　的理由不成立

sen4sun, 我完全被你绕晕了

sen4sun

你是被文章绕晕的　不是被我绕晕的　  嘻嘻。　不要怪我。　

camelhill

sen4sun，你几号考？目标是多少？

sen4sun

我提供一个简单的大纲好了

１。phermones= something elicit a specific behavioral response "unconciously"

2. odorant= chemicals that are "consciously" detected

注意这两个　concious 是不同的

(a phermone can be "conscisouly detected," but it should "unconciously elicits" a specific response)- hope this is clear

3. VNO= chemical signals received by VNO go to the brain without going through olfactory system 意思就是说这些ｃｈｅｍｉｃａｌｓ都不是　ｏｄｏｒａｎｔ　（ｂｅｃａｕｓｅ　ｔｈｅｙ　ａｒｅ　ｎｏｔ　ｃｏｎｓｃｉｏｕｓｌｙ　ｄｅｔｅｃｔｅｄ）

4. phermones are not considered as ordants because people think phermones go through VNO.

5. the author proves that not all phermones go through VNO and not all things go through VNO are phermones, therefore the author is aruging that phermones should be considered ordants.

这样再不清楚我就放弃了。我撞豆腐去了

C 是不可能的 因为早在第一段就说的很清楚

phermones =chemicals elicit a specific behavioral response "unconciously"

文章重心根本不在这

谢谢sen4sun的讲解。

我觉得作者并不是在立论 pheromone就是odorant，他是反驳“pheromone不是odorant”，因此可以看出作者的观点实际上是argue pheromone should be classified as odorants，也就是选项E

如果E选项改为"argue against the evidence and reasoning that pheromone doesn't involve conscious perception，就更好了。。
