回了那么多次贴,自己第一次发帖== 回报CD,祝大家好人有好报!


作文题目是说一个memorandum上出现的关于一个公司是否需要make heavily investment on information technology hardware/software,说可以提高员工的productivity 最终可以导致marginal profit。由于没有背过作文JJ,不知道有没有人放过了,姑且算一个吧--


数学
数学以为能51的,最终还是只有50,想不通想不通。。。感觉没什么题太难的,好多JJ中的题目都出现了,而且一道和除尽除不尽,排列组合的题都没考到......但是要注意,有变体
题目是1. km都是整数,km是一个整数吗? 本来看到想秒选的,但是题目竟然改变了== 没有关于m大于零的选项
(1)km>0 这个没变
(2)改成了m<0
大家考试的时候别秒选==
还有一题是给出公式y=0.5xt^3,问怎样才能使y大于零,是DS题,选项真心记不清了,但是有个跟t有关的,挺绕的不是直观能看出来要推下,有待大家补充哈..抱歉抱歉
还有一题PS是关于整数A,B两数,给出了两个公式能推出AB的关系,然后问选项中哪个可以是B的值,选项是16,17,18,19,20。 可以根据公式推出2A+B的一个关系,最后只有19是可行的,别的都会使A,B不是整数。
逻辑
LZ很没有节操的把逻辑JJ全背了....遇到了好多啊,真心很有用,推荐大家多看看吧(ps 小剧场最有爱了),最后我做还剩下10道题的时候多除了30分钟,印象特别深刻,从来没多出过这么多时间......提醒一点吧,那道广告牌的boldface题目选项还是蛮绕的,要注意推理~ 提供一个错误选项: 加粗的项分别支持了最后的结论。
阅读
4篇全是JJ的,但是一篇关于污染的题目遇到了五道考题......


没了,暂时想不全了,很多都是模糊的碎片,如果有什么残狗可以帮忙回忆神马的, 由于考试V和Q都多出了蛮多时间,所以要回忆还是可以的...但是考好出门左转购物去了== 所以暂时有点模糊,抱歉抱歉


祝大家圣诞快乐!

逻辑新狗印象不深哈,自己出国多年了,其实很多题目都是读一遍读完就选了,没什么记忆。。。如果有新残狗可以帮忙确认!

LZ帮忙确认一下题目好嘛?此篇段意和题目都需要补充呢 谢谢~~


*42. 污染认识转变

一、主旨

有个是讲对于污染的认识转变,应把污染物看成是检测生产中是否有漏洞的指标,以提高生产率的态度来治理污染。/污染是说企业认为环境治理会增加成本。



二、段落大意

P1. 很多company认为控制环境污染会增加不必要的cost,然后作者反驳说环境污染会带来一些潜在的cost, 然后举了几个例子(这里有一道考题问整个潜在的cost怎么解释,我选得是环境污染会在其他方面产生cost, 原文表述这个潜在的cost用了一个什么词我忘了)



P2. 类比说defect,以前公司认为defect是不可避免的,减少defect会增加公司的cost, 但是后来发现,通过改进流程可以减少defect也不会增加cost(有一道题问这段的作用,我选得是类比那个)。



P3. 总结说环境污染也可以像defect一样被控制.然后用了improve processing efficiency来说,其实在治理过程,能发现一些降低成本的地方。/第三段又回头说治理污染方面的事,似乎没有考点。



三、题目

Q1. 主旨题

答案是:提出一个概念并谈了他的影响(V42 by daxian)



Q2. 第二段(defect)的作用

我选得是类比那个



Q3. pollution的opportunity cost指的是什么?

我选的是因为污染产生的lost。

在污染之前就产生的成本。 (V42 by daxian)

狗主解释:解释:有些污染并不是产品释放的,可能因为流程不科学等原因增加原料等从而增加污染。很多污染并不是事后治理的,而是之前就可以控制治理的。因此答案因选之前的成本。大仙对此答案非常自信,这是从经管角度解读的。



Q3.第二段后半截黑脸的作用in order to,

选underline principal 怎样 affect影响了…

迷惑选项:opportunity cost的pricipal怎样apply应用到防止污染。因为本段未提及应用方法,且黑脸前面有一句话:as a result….正确选项带有underline字样。(V42 by daxian)



四、背景知识

机会成本(Opportunity Cost,OC)是指为了实现某个目标而必须放弃的其他收益,又称为“替代性成本”,就是俗语的“有得必有失” -----维基百科,自由的百科全书


三、参考背景



灰常感谢Elaine0905(ID: 676375) 提供英文背景,考古狗主确认相似,尤其是红字部分。

Environmental improvement efforts have traditionally overlooked these systems costs. Instead, they have focused on pollution control through better identification, processing, and disposal of discharges or waste -- costly approaches. In recent years, more advanced companies and regulators have embraced the concept of pollution prevention, sometimes called source reduction, which uses such methods as material substitution and closed-loop processes to limit pollution before it occurs.



But, although pollution prevention is an important step in the right direction, ultimately companies must learn to frame environmental improvement in terms of resource productivity. [1] Today managers and regulators focus on the actual costs of eliminating or treating pollution. They must shift their attention to include the opportunity costs of pollution --wasted resources, wasted effort, and diminished product value to the customer. At the level of resource productivity, environmental improvement and competitiveness come together.



This new view of pollution as resource inefficiency evokes the quality revolution of the 1980s and its most powerful lessons. Today we have little trouble grasping the idea that innovation can improve quality while actually lowering cost.



But as recently as fifteen years ago, managers believed there was a fixed trade-off. Improving quality was expensive because it could be achieved only through inspection and rework of the inevitable" defects that came off the line. What lay behind the old view was the assumption that both product design and production processes were fixed. As managers have rethought the quality issue, however, they have abandoned that old mind-set. Viewing defects as a sign of inefficient product and process design -- not as an inevitable byproduct of manufacturing -- was a breakthrough. Companies now strive to build quality into the entire process. The new mind-set unleashed the power of innovation to relax or eliminate what companies had previously accepted as fixed trade-offs.



第二段用defect做类比  Like defects, pollution often reveals flaws in the product design or production process. Efforts to eliminate pollution can therefore follow the same basic principles widely used in quality programs: Use inputs more efficiently, eliminate the need for hazardous, hard-to-handle materials, and eliminate unneeded activities. In a recent study of major process changes at ten manufacturers of printed circuit boards, for example, pollution-control personnel initiated thirteen of thirty-three major changes. Of the thirteen changes, twelve resulted in cost reduction, eight in quality improvements, and five in extension of production capabilities. [2] It is not surprising that total quality management (TQM) has become a source of ideas for pollution reduction that can create offsetting benefits. The Dow Chemical Company, for example, explicitly identified the link between quality improvement and environmental performance by using statistical-process control to reduce the variance in processes and to lower waste.

多谢JJ整理人的帖子...可惜很抱歉我考的是那个tabacco三个占1%的那个污染,而不是这个cost的....所以这篇没什么办法帮忙啦,抱歉抱歉!!

Ir 由于没看过JJ,所以不知道题目是否出现在JJ上了

我考到的IR印象比较深的是第一题,问的是一个长方形,长增加2宽不变,面积是原来的2倍,假如长不变宽增加2,面积是原来的1,5倍,然后问以下哪个数字分别对应A,B,选项中是3,4,5,6,7


印象深刻是不知道由于我读题失误还是公式列错,算出了两组a和b,由于是第一题,最后胡乱选了其中一个.......
