2.12 一战惨败 愿JJ帮助不是牛牛的战友

stilllife

AA: 11. The following appeared in the editorial section of a local newspaper.

“In the first four years that Montoya has served as mayor of the city of San Perdito, the population has decreased and the unemployment rate has increased. Two businesses have closed for each new business that has opened. Under Varro, who served as mayor for four years before Montoya, the unemployment rate decreased and the population increased. Clearly, the residents of San Perdito would be best served if they voted Montoya out of office and reelected Varro.”

AI: 68. “Since the physical work environment affects employee productivity and morale, the employees themselves should have the right to decide how their workplace is designed.”

Math:

1. 一个人今年的工资比去年多10%，which （注意指的是去年的工资）is 10% less than the previous year，如果前年的工资是S，那么他今年的工资是多少。（答案0.99S）

2. 直线方程aX +bY =c，另一条线与它垂直，且过（2c, 0），求这条线的方程。（注意：Perpendicular垂直的意思，我不认得，猜是平行，挂了……）

3. 一条直线垂直平分一条线段（线段端点分别是（0,0）和（2,0）），这条直线是？答案：X=1

4. 2^51与(2^n)*(3^3)的因子个数相同，求n，答案是12

5. 一个人的平均速度是否小于110km/h？

（1）平均速度大于25m/s

（2）平均速度小于30m/s

选B

6. (x^4-1)/(x^4+x^2)代表的是哪个实数集？答案应该是除了1的所有数

7. X是10-20的一个数，问X是质数吗？

（1）X+1能被3整除

（2）X+2是质数

应该选C，因为X可以是11或17，都是质数

8. 一种什么东西（好像是鱼），各个种类的数量分别是4，5，x，y，z，11（中间三个数记不清了，但我是按升序排列的），一段时间后，原来最少的那种增加了3，最多的那种增加了2，其他增加了1，问现在的range。

答案：7。小心啊，4+3变成7，5+1只有6，最大的11+2=13，所以range是13-6=7，不要看成13-7了。

9. 两圆相切，大圆半径18，小圆半径8，同时两圆都与X轴相切（JJ有），问两圆与X轴相切两点的距离。答案是24。

RC：

第一篇（短）
  

P1一个公司在动态的竞争环境下需要有专人负责进行竞争分析。在选择这样的专人时，可能采取两种策略，一种是雇佣有竞争分析经验的，即在分析竞争方面有专长（expertise）的，另一种是雇佣有整体战略思维的，他们会从更宏观的高度看待竞争。

P2 认为雇佣前者比后者好，后者有弊端，因为这些人往往追求个人事业的成功（类似personal achievement），不太愿意按前人的规章制度行事（这里有考题）。

第二篇（长）：零售店货物摆放（JJ有，但是题目和JJ很不一样！我估计就是栽在这道题上了。四道题的题目至少两道都很长，五六行……）

第三篇（长）：女性工作机会（刚才发现JJ有，但是我没看）

认为男女工作是否应该平等有三个理论模型，一个是open opportunity model，另两个忘记了……主要涉及的是服务业，争论焦点在服务业规模的扩大对女性是否更有利。

第四篇：忘记了，不是机经，长度正好是一页

语法应该没有OG、GWD、prep原题，感觉和prep也不是很像。特别注意，我考的不好，但是到30多题还出现全划线和长划线的题，所以我猜这个应该已经不是区分分数的因素了。

逻辑也没有遇到JJ和做过的题，有好几道evaluate、judge的题，包括倒数两道都是。即使是问加强削弱，问题也都写得很长。

还有一篇GWD原文：

Q36: The passage suggests which of the following about divided demand among a growing number of SKU's?
A. It has increased the average lifetime of products.
B. It has resulted from retailer’s attempts to predict demand more accurately and avoid both understocks and overstocks.
C. It has decreased the use of flexible manufacturing by companies.
D. It has not increased the expense of keeping inventory of certain products.
E. It has not prevented companies from predicting aggregate demand with some certainty.

还有就是这道题，为什么正确答案是 E.？好像文章并没提到 demand divided among a growing number of SKU's 是否妨碍了企业精确地预测累积总需求啊？请大家发表意见。

另外 SKU's 的准确翻译应该是什么意思？

还有一篇GWD原文：

Companies that must determine well in advance of the selling season how many units of a new product to manufacture often underproduce products that sell well and have overstocks of others. The increased incidence in recent years of mismatches between production and demand seems ironic, since point-of-sale scanners have improved data on consumers' buying patterns and since flexible manufacturing has enabled companies to 24 produce, cost-effectively, small quantities of goods. This type of manufacturing has greatly increased the number of new products introduced annually in the United States. However, frequent introductions of new products have two problematic side effects. For one, they reduce the average lifetime of products; more of them are neither at the beginning of their life (when prediction is difficult) or at the end of their life (when keeping inventory is expensive because the products will soon become obsolete). For another, as new products proliferate, demand is divided among a growing number of stock-keeping units (SKU's). Even though manufacturers and retailers can forecast aggregate demand with some certainty, forecasting accurately how that demand will be distributed among the many SKU's they sell is difficult.  For example, a company may be able to estimate accurately the aggregate number of shoes it will sell, but it may be uncertain about which specific types of shoes will sell more than other types.

 

Q35: Which of the following most accurately describes the function of the last sentence in the passage (lines 35-40)?
A. To cite a situation in which the aggregate demand is more important than the distribution of demand among SKU’s
B. To refute an assertion about the side effects of flexible manufacturing
C. To illustrate an assertion about companies' ability to forecast demand
D. To provide an example of ways in which companies address the difficulties of forecasting demand
E. To note an exception to the author's assertion about distributing demand among SKU's

蓝皮书上也有这篇文章。标准答案是C.，可是我觉得D.选项才正确。你的意见呢？

Q37:TTGWD-6
According to the passage, which of the following has led to growth in the number of new products introduced in the United States each year?  The increased incidence in recent years of mismatches between production and demand seems ironic, since point-of-sale scanners have improved data on consumers’ buying patterns and since flexible manufacturing has enabled companies to 24 produce, cost-effectively, small quantities of goods. This type of manufacturing has greatly increased the number of new products introduced annually in the United States.
A. Reduced average lifetime of products
B. Increased ability to forecast aggregate demand
C. More cost-effective ways of keeping inventory for products
D. Cost-effective production of small quantities of goods
E. Increased ability to divide demand among a number of SKU’s and to forecast how that demand will be distributed among those SKU’s
