一、作文：
居然是考了OG13一模一样的题！！！（我也觉得很神奇）现在手头上没有OG13,我电脑上存的“黄金80题” 和“Argument范文OG13标注版” 这题编号是43，手头上有书的同学可以对对。
原题目：
43. The following appeared in an article in the health section of anewspaper.

“There is a common misconception that university hospitals arebetter than community or private hospitals. This notion is unfounded, however:the university hospitals in our region employ 15 percent fewer doctors, have a20 percent lower success rate in treating patients, make far less overallprofit, and pay their medical staff considerably less than do privatehospitals. Furthermore, many doctors at university hospitals typically dividetheir time among teaching, conducting research, and treating patients. Fromthis it seems clear that the quality of care at university hospitals is lowerthan that at other kinds of hospitals.”

译文： 报纸的健康板块上的文章：

        有一种普遍的错误观念认为大学医院比社区或私人医院更好。这个想法是无根据的，我们地区的大学医院较之私人医院，少雇15%的医生，对患者的治愈率要低20%，总体利润要小得多，给一户员工的待遇比私人医院低很多。而且，很多大学医院的医生将他们的时间分为教学，直到研究和看病几部分。从此可明显看出大学医院的服务质量比其他医院低。

范文：

               In thisargument the author concludes that university hospitals provide no better carethan private or community hospitals. The author bases this conclusion on the  following claims about university hospitals:the ones in this region employ 15 percent fewer doctors; they have a 20 percentlower success rate in treating patients; they pay their staffs less money; theymake less profit than community hospitals; and they utilize doctors who dividetheir time between teaching, research and treating patients. This argument isunconvincing for several reasons.

                The most egregious reasoningerror in the argument is the author's use of evidence pertaining to universityhospitals in this region as the basis for a generalization about all universityhospitals. The underlying assumption operative in this inference is thatuniversity hospitals in this region are representative of all universityhospitals. No evidence is offered to support this gratuitous assumption.

                Secondly, the only relevantreason offered in support of the claim that the quality of care is lower inuniversity hospitals than it is at other hospitals is the fact that universityhospitals have a lower success rate in treating patients. But this reason isnot sufficient to reach the conclusion in question unless it can be shown thatthe patients treated in both types of hospitals suffered from similar types ofmaladies. For example, if university hospitals routinely treat patientssuffering from rare diseases whereas other hospitals treat only those whosuffer from known diseases and illnesses, the difference in success rates wouldnot be indicative of the quality of care received.

                Finally, the author assumes thatthe number of doctors a hospital employs, its success rate in treatingpatients, the amount it pays its staff, and the profits it earns are allreliable indicators of the quality of care it delivers. No evidence is offeredto support this assumption nor is it obvious that any of these factors islinked to the quality of care delivered to patients. Moreover, the fact thatdoctors in university hospitals divide their time among many tasks fails todemonstrate that they do a poorer job of treating patients than doctors atother kinds of hospitals. In fact, it is highly likely that they do a better jobbecause they are more knowledgeable than other doctors due to their teachingand research.

                In conclusion, the author'sargument is unconvincing. To strengthen the argument the author would have todemonstrate that university hospitals in this region are representative of alluniversity hospitals, as well as establishing a causal link between the variousfactors cited and the quality of care delivered to patients.

撸主心得：当时看到这题也小吃了一惊，因为这是我上个星期刚练习限时写作的时候练过的题
                这题不算难，攻击点如下：
                1. false analogy：将大学医院与所有其他医院相比较。大学医院与其他医院有好多不同点，例如在规模上，医生质量上，所接纳病人的病情上等；
                2. 样本问题，以偏概全： 仅仅一个region的例子（see red hightlight）就推出所有的大学医院都不好，这种generalization是绝对不严谨的；It is entirely possible that 这个地方的只是一个特例，很有可能在别的地方大学医院成功率就比较高；
                3. low success rate并不代表 low quality of care （如同1中提及的所接纳病人的病情上这一点，如果大学医院里的都是疑难杂症，病入膏肓的病人，而其他医院里的病人都只是小毛病，那当然大学医院的success rate会低）
                4. 其余参照原文吧，其实很多小点都可作为攻击点，例如原文中说的数字15%，20%等，这些既没有证据证明数据的真实性，又没有保证以后都会这样。

二、IR
1. EI投资 （原始稿里第一题）
    三屏，第一屏背景，第二屏first study，第三屏second study. Ethical behaviour and profitability 是EI投资的两大重要指标。EI投资的比例分辨是0% 2%  5% 10% 15%
    详细见原始稿，跟稿里第一题一样，就不复述了：http://forum.chasedream.com/foru ... 6orderby%3Ddateline

2. 选择日期 （稿里暂时没有，残狗，请大大补充）
    某一个地方要办一个fair，fair办完以后有discussion. 两者都在tuesday办，问 number of days between the fair and discussion (好像是)
    选项三栏，一栏fair一栏discussion，后面是天数 （200~300多之间的数，好像有306 这个数）make only one selection per each column

3. ranking method （稿里暂时没有，残狗，请大大补充）
    有100个audience给选手打分，3个级别： 1 2 3； 两种ranking method: mode and median
    下面一个表格，左边是选手，右边是ranking，中间的数据是评分的人数，大概是这样（有些数不确定）：

	级别1	级别2	级别3
选手A	51	20	29
选手B	20	29	51
选手C	0	30	70
选手D	20	40	40

问题问的是 select yes if two ranking methods所得的名次排位都一样

三、数学
撸主的人品大概已经在作文时消耗完毕，数学JJ一道没遇上  能写多少写多少吧
撸主在国外呆了4年后数学智商已为零，恳请各位学霸指错

1. 一个密码有四位, 含26个字母和0到9的数字10个。若是数字和字母能重复使用（can be repeated）, 那么有几种可能？
   既然能重复，那么就都是 36C1， 我的答案是36^4

2. A bird flew from point X, 向西7米，向北9米，向东10米，向南5米到达Y处，求x与y的直线距离
   思路：画个图就清楚多了，上北下南左西右东，实际上就是求直角三角形xy斜边的大小，勾股定理搞定，答案是5


3. 有一Isosceles trapezoid（等腰梯形）ABCD，AD//BC，AB=AC。BC上有点E、F，使得AE垂直于BC, DF垂直于BC。题目告诉坐标如下（数字我不记得了，瞎编的）。求D点x-intercept(横坐标) 超级水题，14
吐槽一下GMAC出题老头，给个图会死么。。。。题目一上来说一大堆坐标，其实画画就出来了。包括那道椭圆操场题，停车场有雪题，鸟飞行题，给个图会死么亲

剩下的有待补充。。。。。。。。

四、阅读
1. 乌龟听力
2. 蟾蜍在死水活水的生活状况
(这两篇在阅读原始里都有,很详细,不再啰嗦,戳http://forum.chasedream.com/foru ... 6orderby%3Ddateline)
3. 污染排放: 讲控制污染排放的几种方法 (emission)
    p1: 介绍控制污染排放，polluters can trade emission permits, 所以污染排放量大的企业会向别的企业trade permits, so that it is cheaper to purchase the permits than to emit pollutant.
    p2: 那么如何定制emission permit的价格呢？ Market efficient的做法是sell it to the highest bidder (竞标)，但后来有的企业觉得不公平，因为原本他们可以get it for free，一旦参加竞标这些permit的价格都会变得很贵（因为是市场推动的）
   P3: 那么如何解决市场价格的不公平呢？最effective最公平的方法是government would impose an emission tax (政府向污染企业征收环境污染税)，后面就是解释如何公平云云。。。

   题目我倒不太记得了。。。。

五、语法
跟27号放狗的大大说的一样，居多平行结构， 具体的考点太细了，有neither....nor, with, 等。。。。想起来在补充

六、逻辑
1. 有boldface的role

2. 某地recession，so people's disposible income has declined. As a result, 许多商家减少了订单，因为他们知道holiday sales的时候人们不会来买定西。但是却有电子产品商家反而加多了订单，相信recession人们会多购买电视。问support
   我选了"recession时人们减少消费，都呆在家里看电视"
   别的选项有“去年这个时候电子产品的销售额很高” 之类

3. 在美国，消费者保护协会为保护消费者不受电话的骚扰，开设了Do Not Call List这一服务。一旦消费者加入了这个list，telemarketer就不会给你打电话了。因此很多telemarketer抱怨说这十分影响他们的生意，但是有business expert说这不但不会使生意下降反而会促进生意，问为什么（justify)
   我选了 “没有加入list的人都是有意向与telemarkete做生意的人，给这些人打电话的potential successful rate and sales会比给一般人打电话要高”


暂时就这么多了，想起别的再上来。撸主考得不好，给各位放狗顺便求求人品

撸主银行全职工作，常加班到8-9pm，晚上回到家已累成狗，几乎都没什么机会可以看书。在这里深深地仰慕下full time工作又能拿700+的大神们！！！32个赞
撸主是请假考的试，明天滚回去继续上班了。。。
这次考试，最大的问题是pace，做到最后一篇阅读的时候根本没时间
所以建议大家，一开始练正确率，正确率到80%以上了就得练pace了，一般是考前两周攻破pace. 你想想，水平就那么回事了，倒不如练练速度（听说没做完的题会double penalty....）
