在职2月无休假，28日半裸考740，饮水思源

meimei0222

本来最后一个星期猛看基金来弥补复习时间不足的缺陷，然而周五杯具地换题库了。。。没办法，上就上吧。感觉碰到的寂静不多，各4、5道的样子。Pace没掌握好，verbal最后十题剩下12分钟的样子，最后一篇阅读题都没怎么看清就乱点，以为肯定会考砸，但出来结果还可以，报学校也够用了吧？所以我感觉前面的准确率还是挺重要的，如果可以的话pace能掌握好就更好了。

我记忆力比较差，只能尽力而为了：
作文题库应该没换，两篇都是题库里的。AA是讲job market in college level teaching position会增加那道。AI是讲individual还是team work重要的issue

数学只记得几道：
1. 开始点X, 向左9米，上7米，向右10米，向下4米到Y, 问X与Y的距离。（具体数字不准）
2. 1/（根号29-根号20）=？
3. 卡片有方，园，三角三种，颜色有红蓝黄三种。方的概率0.5，蓝的概率0.6（数字不准），问两者是否independent
   给了两个条件，但是忘了，这题挺难的
4. 2^(-2), 2^(-3), 2^(-4), 9/(2^7)比较大小

语文阅读：
1. 美国 GDP的那道，寂静上有原体
2. 有一道小鸡凭颜色辨别食物是否能吃的研究，具体内容记不清，看是否有考古
3. Advertising中hierachical model的研究
4. 第四篇时间不够忘了。。。

逻辑及语法真的想不起来了，但语法有很多冒号，破折号等的题，大家碰到时注意下。。。

LZ辛苦了，但从你的回忆我觉得小鸡那篇和GWD里一篇的内容很相似，麻烦确认一下，谢谢：
Sociallearning in animals is said to occur when direct or indirect social interactionfacilitates the acquisition of a novel behavior.  It usually takes the form of an experiencedanimal (the demonstrator) performing a behavior such that the naïve animal (theobserver) subsequently expresses the same behavior sooner, or more completely,than it would have otherwise.  One exampleof social learning is the acquisition of preferences for novel foods.
     Some experiments have suggested thatamong mammals, social learning facilitates the identification of beneficialfood items, but that among birds, social learning helps animals avoid toxicsubstances. For example, one study showed that when red-wing blackbirdsobserved others consuming a colored food or a food in a distinctly markedcontainer and then becoming ill, they subsequently avoided food associated withthat color or container.  Another experimentshowed that house sparrows consumed less red food after they observed otherseating red food that was treated so as to be noxious.  Studies on nonavian species have not producedsimilar results, leading researchers to speculate that avian social learningmay be fundamentally different from that of mammals.
     But Sherwin’s recent experiments withdomestic hens do not support the notion that avian social learning necessarilyfacilitates aversion to novel foods that are noxious or toxic.  Even when demonstrator hens reacted with obviousdisgust to a specific food, via vigorous head shaking and bill wiping, therewas no evidence that observers subsequently avoided eating that food. Sherwin’sresearch team speculated that ecological or social constraints during theevolution of this species might have resulted in there being little benefitfrom the social learning of unpalatability, for instance, selective pressuresfor this mode of learning would be reduced if the birds rarely encounterednoxious or toxic food or rarely interacted after eating such food, or if theconsequences of ingestion were minimal. In a related experiment, the sameresearchers showed that if observer hens watched demonstrator hens reactfavorably to food of a particular color, then observer hens ate more food ofthat color than they ate of food of other colors. These results confirmed that avianspecies can develop preferences for palatable food through social learning.
