2.9 广州少少狗~

alphazeng

本人在职，考试战线拖得很长，其实真正看书也就半个月吧。前两个月每天晚上十点以后才下班，直接导致没有时间复习。考试下来发现没有下苦功夫真的有差，而且，pace很重要！！我每一个部分都很紧张。数学最后两题连题目都没有看就直接乱点了因为只剩二十秒。。。verbal差不多，杯具的是看错了，最后一题还没点就出来time expired了。。。当时想shi的心都有了。心一横点了report。。。690。必须得重考了。希望不要再OT了！平时练习不够啊。。废话一大堆。现在上狗。不过，上了考场才知道大家有多牛，居然都记得题目还有数字。。。我现在是基本上都想不起来了。。。

AA: 说一个神马economic杂志上的一篇memo关于某tire manufacturing company的内容。说是一般来说培训新员工都需要一定的费用和精力，为了节省费用，这个公司实施了一种Apprentice Training Program。这个培训项目的strategy是，公司会给自愿带新员工的senior employee奖金。在培训过程中，新员工跟着老员工学习，follow the pattern of work that the senior employees conduct之类的，因此相关的时间和费用也会减少。然后作者就说，the program should be applied to our company。

AI: Public figures should avoid expressing opinions about things that they have not personally experienced or been directly affected by.

数学（由于考试时间太紧，事后记忆力又太烂，我只有先把碰到的J先列出来了，还有两三道仅有的能回忆起来的，其它的想到再补充。。。大家见谅）

JJ：
3. 10个人里面也四个人懂法文,其他六个人不是懂西班牙文就是懂忘了什么语言(不重样) 从这10人里面选三个,至少一个人懂法文有几种可能
选项好像是 20, 40, 60, 80, 100 （答案100)


7.問m^n 完全平方數嗎
补充:m的n次方是不是一个完全平方数？
1.m是完全平方数
2.n是完全平方数好像是B吧
不一定，比如3^3

补充：

（1）可以 m=k^2m^n=k^2n

（2）不可以，m=2,n=9

选A


10. (a - b + c)/(x - y + z) + R = 0，问R是多少？（加减号不是很确定，不过应该算出来没问题，注意结果有两种可能的表示方法）
Hsien0803补充:注意答案選項把-放到分母就行了
r= - (a - b + c)/(x - y + z)

36. 一个圆柱形油罐车，半径6feet，长9feet，油50 pound/cubic feet。空车重11000 pound，求满车油加车重多少吨（给出pound和ton的转化公式）
M=M车+M油=11000+36π*9*50=61893 pound / 2000 = 31 (约）



59. c糖果由a，b两种原料组成，2磅
a，3磅b组成c，每磅c价格 3.06刀（数不确定）每磅a比b贵2刀.问每磅b多少钱2a+3b=15.3

a=b+2

b=2.26

104. DS一个三角形PQR，PQ=8 PR=4，角PRQ是不是大于90度？
（1）QR > 4.5
（2）QR< 6.5
思路：若角PRQ=90度，那么QR=4倍根号3≈6.82

条件一：QR>4.5没办法推出它与4倍根号3的大小关系不可以

条件二：QR<6.5<4倍根号3→角PRQ<90°可以

答案：B


129. 两个机器A,B. A单独工作每小时生产3onze, B单独工作生产4onze.两个机器工作一共生产了77onze东西,总共工作了14小时,而且任何时候都至少有一台机器在工作.问A,B一起工作的最小小时是多少? 答案有7小时,7又二分之一,8又四分之三等
思路：因为要做满14h，一起时间最少，b就做14h，那么剩下的交给a去做就好，果断7小时

非JJ：
1. DS 两个数列S和T（好像是），各自包含的数字的数目是一样的，问S的median和T的算术平均值谁大谁小。。
(1) S是连续偶数集，T是连续奇数集
(2) S的和大于T的和
我选的C

2. 直角坐标系上的一个square area为1,问以下哪两个点应该落在这个square上。五个选项完全不记得了。。。很简单。

原谅我只记得这两题了，因为今天心情差加重了我的失忆证。。。

阅读：
1. 非洲导演那题，问题记不得了。。。
2. 讲一个人提出的"Cost disease"理论。说一般的industries在几十年的发展过程中都会因为技术的提高等原因使得cost下降，但是music performance这个行业不同，因为不涉及很多技术的东西所以没有改进也没有使cost下降。
第二段说另一个人提出反对的意见，说music表演行业也有技术设备之类的改进。记不得了。。。
第三段说第一个人在提出理论的时候忽略了一个重要问题，就是那些大牌演员的要价问题。说classic music行业，有一小群占着dominant地位的经纪人什么的，为这些大牌开很高的价。。。（这里有问题，好像问文章讲第一个人忽略了什么：是开高价的演员，还是拿很高pay的经纪，这两个选项想了一下，还是选了前者）
由于本人看的复习材料实在有限，所以不知道这个在不在之前的JJ里。我在网上搜了一些关于cost disease的资料供参考（当然这基本上和第一段有关，帮助大家了解下背景吧。。。）
Baumol’s cost disease (also known as the Baumol Effect) is a phenomenon described by William J. Baumol and William G. Bowen in the 1960s. It involves a rise of salaries in jobs that have experienced no increase of labor productivity in response to rising salaries in other jobs which did experience such labor productivity growth. This goes against the theory in classical economics that wages are always closely tied to labor productivity changes.

The rise of wages in jobs without productivity gains is caused by the necessity to compete for employees with jobs that did experience gains and hence can naturally pay higher salaries, just as classical economics predicts. For instance, if the banking industry pays its bankers 19th century style salaries, the bankers may decide to quit and get a job at an automobile factory where salaries are commensurate to high labor productivity. Hence, bankers’ salaries are increased not due to labor productivity increases in the banking industry, but rather due to productivity and wage increases in other industries.

The original study was conducted for the performing arts sector. Baumol and Bowen pointed out that the same number of musicians are needed to play a Beethoven string quartet today as were needed in the 1800s; that is, the productivity of Classical music performance has not increased. On the other hand, wages of musicians (as well as in all other professions) have increased greatly since the 19th century when not adjusted for inflation.

In a range of businesses, such as the car manufacturing sector and the retail sector, workers are continually getting more productive due to technological innovations to their tools and equipment. In contrast, in some labor-intensive sectors that rely heavily on human interaction or activities, such as nursing, education, or the performing arts there is little or no growth in productivity over time. As with the string quartet example, it takes nurses the same amount of time to change a bandage, or college professors the same amount of time to mark an essay, in 2006 as it did in 1966.

Baumol’s cost disease is often used to describe the lack of growth in productivity in public services such as public hospitals and state colleges. Since many public administration activities are heavily labor-intensive there is little growth in productivity over time because productivity gains come essentially from a better capital technology. As a result growth in the GDP will generate little more resources to be spent in public sector. Thus public sector production is more dependent on taxation level than growth in the GDP.

暂时写到这里吧。昨晚就是三点多睡的，直接导致考试精神不济。。。明天又要回万恶的公司上班去了。。。再接再厉，争取二战时记住多一点发给大家。祝大家考试顺利！！成功进入自己的理想学校！！
