8.11二战----感谢CD+感想+jj

今天下午场，先来CD再说。是二战了。一战后看了NN们的帖，受益匪浅，之前只把OG做过一遍而已，后来才知道OG是根本中的根本，一定要多看多研究，不懂的地方就上讨论版，近年来的讨论明显没有以前那样的感人的激烈，因为前人们已经讨论很得够透彻，看着一道题从cr版再到sc，真的是崇拜，这也是这次最大的感受：钻研精神--------------一定要好好学习，CDer们对英语的研究让我看到自己做得还很不够。

也许大家都知道了OG的重要性，但还是再提一下，还有GWD，都是最重点---------希望像我当时一样不了解的朋友看到，

总之，感谢CD。

来说下jj，一直在想，可是太散了，佩服那些记得轻轻楚楚的朋友，我会看帖，想到了补充

这里说一道觉得很妙的math：一个整数x，各位相加为170，还知：x=10^20-y, y是某个两位数，问y可能的值------------------因此，x为一个十九位数，而且前17位均为9，因此后两位和为170-17*9=7，因此可选出答案------怎么好像和当时算得不一致，可能记错了，大家看看题型和思路就好了

刚刚怎么忘了awa呢，来补充：aa，a well-equipped gym to derease cost of group health insurance coverage and thus to achieve budget balance那道；ai，the reponsibility of preserving the natural environment ultimately belongs to each individual person rather than government, 都是golden80上的题

jj重整，为了方便大家，把散乱的jj重新梳理补充，节省大家宝贵的时间：

RC：1. CO2, SO2----------见300；做题时看仔细到底是CO2还是SO2

2.       三段，较长，第一段提出通常观点认为之前妇女地位好很多，而且还有些财产，然后作者反驳了，说从两方面看都不是这样的（记得不太清，很需要补充，以免误导）；第二段提出了一些evidence以支持；第三段讲两个学者提到妇女在当时有工作，作者反驳说他们的研究不充分，没有跟men的情况进行比较，这里有态度题-----------这篇被17楼的Mcbee找到了：Traditional social science models of class groups in the United States are based on economic status and assume that women's economic status derives from association with men, typically fathers or husbands, and that women therefore have more compelling common interest with men of their own economic class than with women outside it.  Some feminist social scientists, by contrast, have argued that the basic division in American society is instead based on gender, and that the total female population, regardless of economic status, constitutes a distinct class.  Social historian Mary Ryan, for example, has argued that in early-nineteenth-century America the identical legal status of working-class and middle-class free women outweighed the differences between women of these two classes:  married women, regardless of their family's wealth, did essentially the same unpaid domestic work, and none could own property or vote.  Recently, though, other feminist analysts have questioned this model, examining ways in which the condition of working-class women differs from that of middle-class women as well as from that of working-class men.  Ann Oakley notes, for example, that the gap between women of different economic classes widened in the late nineteenth century:  most working-class women, who performed wage labor outside the home, were excluded from the emerging middle-class ideal of femininity centered around domesticity and volunteerism. ---------具体出处了解了再补充

SC：实在记不得具体题，总之平行结构出现很多，而且通常是要根据句意择优

CR：1. 供应商（批发级别的）出售的商品价格上升，总收入也上升，可profit却下降，要解释----当然是cost在上升

这是出现在很前面的，所以清楚些，别的零零散散坚决不说了，以免误导，个人觉得CR最可能误导人，大家看jj时谨慎些

MATH：1. 一个整数x，各位相加为170，还知：x=10^20-y, y是某个两位数，问y可能的值------------------因此，x为一个二十位数，而且前18位均为9，因此后两位和为170-18*9=8，因此可选出满足条件的答案（谢谢knowcking的纠正）

       2. 遇到了学校选代表那道，即C（6，4）

       3. 一个圆o，一弦ac与半径ob垂直于d，知道ac=12，bd=2，求圆周长

       4. 星球中心距离那道---------jj中即其说得是很清楚的，两个条件都描述得正确

       5. 河水位某一刻的值是x，高于平均值y a%，问x低于警戒水位z的%：condition一个是关于%，一个是关于绝对数

       6. 公司-个人-总福利费那道关系没看明白的题-------请留意

LZ说的好～ OG十分重要～～～～！！我也快考了，呆会儿再看一次OG

请加油想想鸡精，作文的题目应该记得吧？ 多说一点也会对广大CDER很重要的

赫赫，我一点发送就想起来怎么连作文没写

还有，我遇到了so2，co2那篇；其他的好像没见jj中有
