lz现在很绝望 二战了 分数都一样。 不知道该不该继续调整心情 先放狗吧


作文 JJ上好像没有
是说把sandwich shop converts into a burger restaurant的. 可以lower costs, attract consumers。所以burger店的店长建议该地区的sandwich shop都能转换成burger店。 这篇很好写, 考个古吧。


IR
1. 考到了作家的题,就是reviewer和author的那个。primary reviewer之类的。JJ上有,很全
2. 逻辑题。A说应在uptown建车位,因为该地停车场不够用,人已经饱和了,不能再建楼了,除非建些基础设施。B说在地铁站附近有楼房。JJ第24个
剩下记不住了。


数学
这次数学我觉得比我一战时候难好多。
1. 最后一个题 纠结了好久。是说一个工厂每5s(还是6s忘了)manufacture60个nails,,每9s packed100个nails。at the beginning of the shift,1000个nails 没有被packed,问 过了2个小时之后 多少个nails 没有被packed?
2. 还有那个题,以8、8跟好2 为边长的矩形被挖掉两个以y为边的正方形,这个题考试中没有那么简单。说y=1/16矩形的周长(lz不解 矩形的周长是指直接按两条边算,还是还有按加上挖掉的那两个小正方形的边长算)
3. 有道题说x inversely 和y的平方成比例。说y=2时,x=500 问y=10是,x是多少?


阅读
题目都是JJ上的
1.working memory
2. creditor和debtor
3. 音乐剧价格的提高 具体不太记得了大概是 较长(目测JJ上那个cost disease music 和音乐剧的提高是同一篇。)
P1 B某人提出了一个theory, 大概解释了一下
P2 economist可能同意B的观点,但谁谁不同意,因为没有考虑到technology,举例现在许多bands用乐器来吸引观众,什么drum啊
P3 另一拨人反对B 因为他没有考虑到higher pay fee to the musicians 一些agents 和administrations 愿意给自己artists要价更高
还有一篇我忘了。


逻辑
最烂的一部分,所以忘了。不好意思

请LZ帮忙补充一下阅读整理好好嘛
27. 大脑working memory*(谢谢Jocob)
一.文章主旨

新老观点对比,然后某人用实验证实了新观点。



二.段落大意

P1:第一篇是 working memory(WM)讲大脑记忆。先说一个理论,解释“WM”是什么,就是短暂记忆,人们平时用于记电话,读一个句子理解前后文时的短暂记忆。

提出旧观点:executive system理论,说大脑活动区域以前认为当人受某刺激时(貌似。。。),大脑的反应是在cortex(皮层)外面。且传统观点认为大脑的EXECUTIVE INFORMAITON CENTER 管理信息处理,一个区块统一负责处理很多记忆。

新观点:但好像有人(某科学家GP )提出可能是在里面/认为大脑接受信息的功能由前额后面的一个地方负责。并且分为不同的sub-regions, 一个管理information, 一个记忆appearance/如空间信息,形象信息等每个sub-region针对不同性质的刺激,有分工。这个理论推翻了之前的理论。



P2:貌似是某实验证明确实如同那个人所说,活动在cortex里面。/说了mir的理论,用MIR这种方法来pinpoint大脑在用“WM”时的具体活动位置,实验发现:when recognize faces, the middle part of cortex is most active. (此句有题)。实验加强了第一段中新观点的理论。



三.题目

Q1. 我考到了MAIN IDEA/主旨题:这个D的发现的意义是什么

应该就是一个新理论什么的,很好选的(本月V34狗主)



Q2.还有1道是关于 EXECUTIVE SYSTEM和那两个理论的对比还是区别之类的。



Q3.问题有一道较难 就问第二个人的发现可以用作什么的证据?/有1题是问这tech的新发现证明了什么理论是真的(来自考古,本月狗主选择与考古V1相同)

V1我选的是:the middle part of cortex is most important to working memory 类似的,不知道是不是对这篇整体感觉挺难的 大家小心

V2我选新观点是对的。



Q4.有一题,mri的作用是什么。(来自考古)



Q5.问题中问如果试验出什么结果,就会greatly undermine那个女科学家的理论?



Q6. 问哪个是作者的观点?

狗主解释:就给了四个句子,从文章中都可以判断。主要要记住的就是不只有executive function在cortex,不同功能的sub-regions什么的也在cortex(本月V34狗主)


3.  第三个问那个第三段face的实验有什么作用?

进一步论证了第一段里面sub-regions也在cortex(本月V34狗主)



狗主解释:我看到前面有狗主选的是middle part is most active,我考试的时候想了半天,个人认为应该选进一步论证了第一段里面subrigions也在cortex才对



四.备注

1)这篇很短的文章开头前两句好像还是废话类似于背景那种引出话题怎么记忆电话号码之类的。

2)这一篇很多很多生词,短而难。

Working memory is the process of maintaining a limited amount of information in an active representation for a brief period of time so that it is available for use. Therefore, by de¢nition, working memory includes those processes that enable us to hold in our `mind's eye' the contents of our conscious awareness, even in the absence of sensory input. Thus, the study of working memory provides a framework for investigating the neural system underlying our awareness of stimuli, memories and knowledge that are no longer tied to perceptual events. Although the neural system responsible for working memory is known to include a large number of brain regions, there is abundant evidence from neurophysiological and lesion studies in monkeys that prefrontal cortex is a critical component (Fuster 1990; Goldman Rakic 1990). Recent brain-imaging studies, using positron emission tomography (PET) and functional magnetic resonance imaging (fMRI), have also implicated the human prefrontal cortex in working memory. However, there remain questions and somedispute about the functional organization of the human prefrontal cortex and its exact role in working memory.



Here we summarize the evidence for working memory-related activity within human prefrontal cortex. We then present evidence for domain speci¢city within frontal cortex for object working memory as opposed to spatial visual working memory. We also review evidence suggesting an additional dimension of domain speci¢city for object working memory based on whether the type of representation is analytic or image-like. In addition, we discuss evidence suggesting a third dimension for the specialization of working memory function in prefrontal cortex that distinguishes regions important for the maintenance of the contents held in working memory from regions important for the manipulation of those contents.



Finally, we consider the relationship of prefrontal areas important for working memory, both to posterior visual processing areas and to prefrontal areas associated with long-term memory.

谢谢亲。
working memory这篇跟JJ文差不多。
P1 引出wm 说可以记电话什么的。 解释了一下什么是wm。P提出了关于wm的什么theory, 认为brain active都在里层,而不是cortex(好像是 lz记不太清了 但题目有考他的理论)
P2 另一个理论证明p说的正确 举了个栗子

请确认作文:
the following is a newsletter from the Director of Mega Burger franchise Store to the Cindy's Sandwich Store:
Mega Burger, which is the largest national chain store, invite Cindy's sandwich store to convert into the Mega Burger store. Such convert can reduce the operation costs. In addition just as people who go to clothing and home-supply store prefer the well known store, so do people who go to restaurant prefer the meal they known
