祝所有还在奋斗的CDer们节日快乐!!!

今天还在做的预习作业:

管东卫数学光盘讲解笔记

1、
                            
思维陷阱

出现的原因是不客观的思考,想当然;整不整,正不正,等不等;不是不等式就一定求不了具体值;排列组合中也有陷阱,要判断是否分堆;概率中的陷阱,是否独立;集合论中,子集之和是否是全集;

执行:注意解题的客观,永远不要想当然;关注问题所问与条件的差异;对于数字而言,公式有了仍就需要计算;任一条件都是一种限制,有限制和没限制是不一样的;考虑特殊值,0,12,如分母不为零,非零的零次方才能为1

2、
                            
知识点遗忘

4.1单利single 复利compound 注意是年利还是月利

4.2几何 记哪些是直角三角形 3*3945 5*5251213 任一一奇数平方后分解两个相邻两数的和;一个外角等于两个不相邻的内角之和;大角对大边;同弧对应的圆心角是圆周角的两倍;弧长/圆周长=弧所对应的角度/360度;以直径为一边,圆外为锐角,圆周为直角;菱形,对角互相垂直且平分,所以面积是对角线相乘除以2n边形内角和为(n-2)*180;立体几何,球和圆椎不用管。

4.3平面直角坐标系 各种对称点的坐标;解析几何,截距有正负,为与坐标轴相交交点处非零的坐标值;两点之间的距离;直线方程 斜率是最重要的;抛物线方程 

4.4 数列 等差数列,以算术平均值为左右对称;等比数列,任何中间项的平方是前后项的乘积

4.5集合论 经常要画圈;IABAB+非AB IABCABBCCAABC+非ABC;两种关系,即画两维表格

4.6计算能力 如何能简化计算,关注变化量

4.7代数 比例较多;因式分解;不等式,分式不等式转为乘积不等式;二次不等式;
        

3、
                            
有难度的知识点

5.1 统计知识点 mean算术平均值; mode众数 出现最多的数值range 最大值与最小值之差;median 中数,有序排列后,奇数个数的中间数,偶数为中间两数的算术平均值,中值,对于连续量,是最大值与最小值的算术平均值, 两堆合并后中数及平均值均在原两堆各中数及平均值之间;deviation 标准差 反映距算术平均值的偏移程度, 加入的数是在算术平均值+标准差及算术平均值-标准差这个范围内,会使数堆的标准差减少;标准正态分布,即以算术平均值为轴左右对称

5.2 04/01:00:0005/00:48:00 排列组合 C指不可区分,P指先取完再排列;排列组合题的思维过程 看问题是否要分类考虑,注意不重且不漏,按顺序,在每类计算时,要坚持原则是先计算有限制的或数目多的,再计算无限制的或数目少的字母,在任一个局部的计算中坚持先考虑如何取,再考虑如何排(区分);加法原则和乘法原则,加法原则问这件事完成没有,完成了是加法,没完成是乘法; 需要将题目转化为排列组合,研究明白问题的实质

5.3 概率 分子是满足问题要求的所有情况,分母是所有情况;无限制就是全概率事件,就等于1;独立重复事件发生的概率。概率中的注意点:是否独立;概率包括排队组合,有与集合论相联系的可能;

5.4数论 数论的各种概念 负数也有奇偶概念 0是偶数 质数只说自然数所以负数一定不是质数;互质数 两数最大公约数为1,任两个连续自然数都是互质的;任一个大于等于四的偶数都可以表示为两个质数和的形式;最大公约数,所有质因子取出并取最小幂,最小公倍数,所有质因子取出并取最大幂,两数相乘之积为最小公约乘以最小公倍,最小公约数也可用辗转相除法得到,(60/3624, 36/241224/120,则最小公约数是12;然后最小公倍数就等于60*36/12

英语难句读法

1、  正确的阅读应该是,如何读一遍就能把握到句子的大意,抛弃语法结构和语法分析,可以多关注句子的感情色彩。

2、  词汇要注意其引申意思,学会在文章中理解单词,将单词抽象为一个模糊的概念,注意动词和形容词的变化和引申。另外还有一个单词广度的问题,只关注认识的单词,并将它们连在一起对整段进行理解。

3、在句子中创造断点:断点内句子具有最简洁的完整性;在被断开的各部分间加入连接词。

5.4数论 数论的各种概念 负数也有奇偶概念 0是偶数 质数只说自然数所以负数一定不是质数;互质数 两数最大公约数为1,任两个连续自然数都是互质的;任一个大于等于四的偶数都可以表示为两个质数和的形式;最大公约数,所有质因子取出并取最小幂,最小公倍数,所有质因子取出并取最大幂,两数相乘之积为最小公约乘以最小公倍,最小公约数也可用辗转相除法得到,(60/3624, 36/241224/120,则最小公约数是12;然后最小公倍数就等于60*36/12;整除,余数,因子,2 4 5 8的余数都是最后两位数余数为几就是几, 11的余数是错位相加再和相减,1983056――>(1806)-(953)不为零,所以不能被11整除。3,9的位数,各位相加除以39余数是几,那么原数整除就余数几;被9整除的特点,ab-ba一定是9的倍数,ab+ba一定是11的倍数,两位数两位的差值就是ab-ba对于9的倍数,两位数两位的和值就是ab+ba对于11的倍数。如何理解同余的概念,被3除余1,被,4除余2,被,5除余2:[1333]+121212 每次加前两数的最小公倍数,这个数就是符合条件里最小的数。复杂幂指数的余数计算:第一步将各各数分开算,先底数后指数,指数化简到1,再进行计算。任何数的因子,先将数表达成质因子相乘的形式,再将幂加一相乘;N如果有奇数个因子,那么它一定是完全平方数。尾数循环的特点,幂数除以一个循环内的个数,余数就是对应的尾数位置;奇偶的概念:N为偶数,N2N的质因子相等。记一些特殊的值:2 4 8 16 32 64 128 256 512 1024; 阶层  1 2 6 24 120 760;0.5 0.333 0.666 0.25 0.5 0.75 0.2 0.4 0.6 0.8; 1/6=0.16 5/6=0.83 1/8=0.125 3/8=0.375; n/9 就是0.n 循环;1/7 0.142857 2/7 285714 以排第N小的数开始循环

GWD数学特别是数论部分听一遍还是有许多不懂的地方,给出的方法里也有许多不记得的,第二遍的复习是必须的了。

  

作文光盘课笔记

作文光盘课笔记

1、  两类作文在内容上的要求

内容是语言的基础,如果内容不合要求语言再好也不能得分。

ISSUE 观点明确,选择支持或驳斥;论述的多样性;论述的多面性;论述内容丰富且有深度;测试点以语言能力为主

ARGUMENT 观点明确,找出各种逻辑错误;逻辑清晰;错误点正确;内容丰富;以逻辑推理和逻辑思维为主

ARGUMENT 错误在哪 一共七类错误

现象类错误 列举的现象主观被认为就是另一个现象的联系,而这种联系并不一定是客观存在的,起码存在的理由和证据并未给出。

范围类错误 将原因中的范围发生不合理的扩大,缩小或转移,而推导出的错误结论。

偷换概念类错误 在结论中用一个表面类似的概念偷换掉原因现象中的概念。

割肉类错误 未考虑边际效益递减的趋势。

循环认证型错误 将不一定对的结论当成事实来循环认证这一个结论。

动静态性错误 由一个静态的过程推出动态的结果,或者反之。这类错误起来会很合理,这时可以考虑这类错误了。

比较类错误 现象中的比较与结论中的比较对象不一致而导致的结论无法推出。非常多的情况是,现象中是对象自身的比较,而结论中是对象A与对象B的比较。

ARGUMENT如何根据错误类型给出一个详细模板(四段):找出错误,错误有N个时,先确定哪个是主要错误,或哪个是比较好写的错误;

第一段 根据原文所说,我们可以看出A能够推出B,而这个推理至少依赖于两个假设,首先它假设AB有必然联系,其次它假设了并不是A之外的因素影响了B,但这两个假设是站不住脚的;

尾段,综上所述,这个推理是有一定缺陷的,如果作者能把上述的错误纠正,且能够提供额外的证据证明AB存在的真实性,或者其它逻辑错误是站得住脚的,那么这个推理会变得更加严密;

中间段落,首先说具体的推理错误,即刚说的七类错误,再有一段写它因。

它因段的写法:其次,从原文我们能够看得出,得出的结论是B,而根据我们的生活常识,或科学知识,我们知道,对B而言,我们可以从CDE等几个方面来探讨B存在还是否存在。但在我们刚才看到的论述中,即没有看到除A之外,CD等原因是否存在,也没有告诉我们在对于B的影响上A是比CD更加重要的。那么,在这种情况下就认为只是A而不是其它因素导致B的就太武断了。

现象类错误模板:原文之所以认为A能推出来B,不过是因为A是先发生的,而B是后发生的。但我们知道有时间先后关系的两个现象不见得有必然联系,否则我们可以设想这么一个事实,C能推出来B,这是一个多么荒唐的结论。

范围类错误模板:原文这所以论述A能推出B,不过是因为A是一个局部的数据,而B是一个整体的数据,但我们知道局部不一定能代表整体,而整体也并不一定能代表局部,因为局部有它的特殊性,而整体有它的一般性,否则的话,我们可以假想这样一个事实,(加入一个范围类错误的事实),而这是一个多么荒唐的结论。

偷换概念类错误模板:原文这所以论述A能推出来B,不过是根据ABC上有一定的相似性。但是AB毕竟不是完全一样的东西,因此它们两之间也不见得有必然联系,否则的话,我们可以做出一个相似的推论,(加入一个偷换概念类错误例子),而这是一个多么荒唐的推论(难道这是一个合理的推论吗)。

循环认证类错误模板:原文在推理过程中,在结论B得出之前,在某处已经把B当成一个正确的事实使用过了,而这就是犯了循环认证的错误。也就是说,原文的推理过程,可以简化成B推出B,而这个推理从本质上讲是和A没有任何关系的。

割肉内错误模板:原文在推理过程中认为AB是有必然联系的,这个思维是不严紧的,因为若想得到B,必须保证某个东西是必然存在的,而从原文的推理中,我们可以看出作者主观的认为这个东西必然存在,但是这个东西是否存在是需要有确凿的证据来证明的,而不是靠一个人假想来证明的。正是由于这个推理的不严密,使得AB有必然联系,这个论断站不住脚的。

动静态错误模板:首先,原文仅仅考虑了有A就会有B这个部分事实,但常识告诉我们,有些有A的人,根本就没有B,而有些有B的人,根本就没有A,其主要原因就是,因为A是在阐述一个东西的过程,是动态的,而B是在强调一个事情的结果是静态的,但动态与静态这两者的关系不是必然的,而这些因素使得,上述AB有必然关系的假设站不住脚了。

比较类错误模板:首先,原文在推理过程中是在对比两个东西,而对比的这个东西在其上结果上所反映的是其概率是大还是小,而就我们的科学知识而言,概率所反映的是,在总集中满足这种条件的反占的百分比。但在上述的推理中仅仅对比了两部分群体中满足条件群体的量,而忽略了影响概率值的总量,这就使得现在所在的比较是一种绝对化的比较,而不是相对化的比较。也就导致了,原因和结论有必然联系的这个推论点站不住脚。

 

ISSUE 最好写成五段,开头段表明观点,中间三段从不同角度论证自己的方向,尾段

第一段:(先有引子引出观点,而不是直接说出观点。)在日常生活中,我们会遇到许许多多值得推敲的问题,当我们见到作者提出这样一个观点,我们应从什么角度来考虑这个问题呢?有的人认为____,而有的人认为______。而我的生活经验使我认为____是正确的。

尾段:(总结前面的观点,补全充分性)综上所述,我认为___是合理的,当然就这个问题而言,如上所能讨论的原因仅仅是从几个大的方向认证了这个观点的合理性。除此之外,我们还可以在一些小的方向,如生活,工作继续探讨这个话题,比如___,这个例子也是挺合理的。在讨论了这么多方面来认证这个观点的合理性之后,难道你还认为这个观点是可以的吗?

中间段:从不同的角度来论证自己的观点,A表明为什么我会有这样一个观点,B如果我持有这样的观点的话会带来什么样的好处,C为了实现这个观点我们应当如何去做

Tip当话题比较抽象时就很难想出一个原因时,可以重述,用不同的方式将话题重新说一遍

感觉的作文没有XDF的讲得好。。。个人感觉

终于结束预习听课了。。。。明天开始难句和OG

1、
                            
数学最后的难点

原因:没做到把题目转化为数学概念;欠缺数学中的思想 固定即考虑不变量 极值思想考虑最大值或最小值;研究问题的意思,极限的思想,趋进即相等

各种数学方法:数形结合思想,特别是集合的题;极值法;代入法,简化,简省变量;设1法,在计算题不给值只给比例时,设总量为1;排除法,列举选项的用选项排除,数据充分性的构造不同的情况;对称性;归纳法;求极值可以取导数;若出现特别难的考题,要注意深度理解题目,另外有些题是不计分的,所以调整心态,计经中的难题要注意做;

2、
                            
问题求解与数据充分性的小技巧总结

问题求解的技巧:根据答案凑数,一般从C这个中间选项开始试,根据试的结果调整洁试的范围;条件不清时应立即检查条件,重新列举。

数据充分性的技巧:客观;思维清晰,;学会运用答案中的相关性,通过选项中的共性来猜答案;什么是数据充分性,不是要我们算出来,是否判断可以算出来,是是唯一的;考虑特殊值;构造是否存在不同情况; 

作文太没内容了,不贴了

以下是引用gloven在2009-6-6 9:33:00的发言:
davina 你有几天没更新了?

电脑坏了,正版的vista被我整没了! 不过这几天还是有学习的。先是做完了OG11的逻辑题,然后做了一套GWD。总结了一下紫皮书上的阅读,发现还是不得要领。

首先分享一部分逻辑题的笔记。

笔记范围:OG11的逻辑部分
            

完成了OG11的逻辑部分124题,题目的难度在
            

笔记明显比做review逻辑是笔记减少了很多,在练习时对正确问题提出的关注也使自己在做某些题目时几乎可以在浏览选项前就猜出正选的逻辑思路。现在最大的问题是,如何在没有看懂题干时尽量的排除错误选项,也就是管老师说的不是通过文章来解题,而是单纯通过判别有关无关来解题。事实上,许多削弱题会通过他因来削弱,要判断有关无关难度就更大了。
            

T12 在这个cable-television的题中,people who do not watch television are irrelevant to the argument,这是另一类分类错误。练习练习分辩哪些分类是无关分类。
            

T14 难句 within 20 years it will probably be possible to identify the genetic susceptibility an individual may have toward any particular disease.

T25 假设题中,前置假设与后置假设给予逻辑角度是不一样的。前置假设是直接推了结论的假设,他表现为架桥式加强,一定是前面的条件与后面结论断桥的补充。
            

T27 此为后置假设,在前文的逻辑推理不存在断桥时,给出的假设通常只是对原条件的改写。Bicycle racers do not generate a strong demand for innovations that fall outside what is officially recognized as standard for purposes of competition. 这个选项其实是对 the only cyclists seriously interested in innovation and willing to pay for it are bicycle racers.的原因的一个解释,也是对结论中否定式肯定结论的解释,这里并不存在架桥。
            

T34 for the balance的理解是解题的关键。
            

T43 其中对opportunities的理解,就是从机会成本和机会收益角度去考虑损失。
            

T44 which calls into question the explanation above? 这是削弱选项的另一表达。
            

T45 whereas: formal used to say that although something is true of one thing, it is not true of another

T46 C选中只说明了如何保证销量没说明如何维持价格, 而结论中也说到了if classical economics is true即在这个前提下, 价格已经是平等的了,从价格上考虑利润已经不行了,只能从销量考虑.

???T48 Indeed, any forager society with which anthropologists are familiar has had considerable contact with modern, non-forager societies.

???T51

T53 有一种看懂的感觉,能接收到的信息只限于一种怎么样的塑料容器由小的塑料粘合成。只能只有粘合材料能降解,最后剩下小塑料,最后一句
    no less plastic refuse per container is produced when such containers are discarded than when comparable nonbiodegradable containers are discarded
。如何解
            

trash compactor a machine that presses waste material together into a very small mass/ not ... any the less/no less (=not less) Your second point is no less important.It's a common problem but this doesn't make it any the less disturbing.I know he's done a dreadful thing, but I don't love him any the less./ discard o get rid of something

不过这题从管老师说的信息有关无关考虑,Arefuse compactor是无关的,Cprefer to buy consumers是无关的,DE无法排除。
                

T56 underrepresentednot on councils

T57 the number of people for whom seeing an excerpt of a book in a magazine provides an adequate substitute for reading the whole book is smaller than the number for whom the excerpt stimulates a desire to read the book./Excerpt: a short piece taken from a book, poem, piece of music etc

T59 句中的结论是however所引导的部分,应该对这一转折进行支持
                

T61 在类似于成本收益这类题中,重点是改变的部分,哪一部分的成本和收益是改变了的。
                

T62 reveal absurdity of the conclusion 削弱的另一种说法/absurd: completely stupid or unreasonable

T68 这就是一个很难理解原文逻辑的逻辑题,很绕,因为原文中有一个逻辑悖论,而选项还是用问题的形式回答的。
                

T69 excavation:
   
if a scientist or archaeologist excavates an area of land, they dig carefully to find ancient objects, bones

T70 针对一段话提出两个问题时最能看出相关与不相关不是仅仅与文章有关的,还与问题有很大的关系,这两个问题很可能一个是针对段落中的现象提出的,一个是针对段落中的结论提出的。
                

T73 visual image: relating to seeing/
   
Artists translate their ideas into visual images.

T74 exempt from: not affected by something, or not having to do it or pay it/ The interest is exempt from income tax .

T81 名词的细节限定,这个考点在数学中也经常出现:3% of drivers33%of all vehicles ticketed 可以看出,后者在全集范围上已经进行了缩水,从全部驾驶员缩减到了被罚的那群人。

今天周末,多发一贴

GWDTN练习中阅读部分的分析汇总。主要是按管老师说的方法进行抽象和总结。

GWD05年录音听课笔记

1、  不能有不读的地方,只需准确快速的定位及如何初步有效分析问题使干扰选项的干扰度降低。

2、  阅读的步骤:第一步是先读原文,重点是怎么读,怎么记;第二步读问题,不要一看题就马上到文章里找,要先对题干进行分析后再做题,重点是选项挑选的方法

怎么读:读文章,整篇文章不是一个整体,而每段是一个整体,任一段的第一句是最重要的要慢读,其余部分可以快读。一但发现比较点,观点结论性的句子。另外,整篇文章的最后一句话要注意。快读地方的阅读重点应该是名词

问题中,if only等限定词很重要。读到问题后,先根据自己对原文的记忆分析问题,排除若干干扰选项。

一定要坚持傻子原则,不要自己乱加东西。机考一篇文章只出34四题。

GWD-8-Q4-Q6

       Frazier and Mosteller assert that medical research could be improved by a move toward larger, simpler clinical trials of medical treatments. Currently, researchers collect far more background information on patients than is strictly required for their trials—substantially more than hospitals collect—thereby escalating costs of data collection, storage, and analysis. Although limiting information collection could increase the risk that researchers will overlook facts relevant to a study, Frazier and Mosteller contend that such risk, never entirely eliminable from research, would still be small in most studies. Only in research on entirely new treatments are new and unexpected variables likely to arise.

        Frazier and Mosteller propose not only that researchers limit data collection on individual patients but also that researchers enroll more patients in clinical trials, thereby obtaining a more representative sample of the total population with the disease under study. Often researchers restrict study participation to patients who have no ailments besides those being studied. A treatment judged successful under these ideal conditions can then be evaluated under normal conditions. Broadening the range of trial participants, Frazier and Mosteller suggest, would enable researchers to evaluate a treatment’s efficacy for diverse patients under various conditions and to evaluate its effectiveness for different patient subgroups. For example, the value of a treatment for a progressive disease may vary according to a patient’s stage of disease. Patients’ ages may also affect a treatment’s efficacy.

第一段:FM要用简单的实验治疗来改进Medical研究方法。然后有说到这种改进的风险。

第二段:FM不仅限制了数据使用还要求实验治疗中更多的接纳病人,这里在说改进的另一方面措施。接着对这一措施进行了解释与分析。

另外借鉴一下网上给出的逻辑简图:

1P: F and M assert that research improved by….. Currently… although, F and M contend that….

2P: F and M propose not only…. .but also, thereby obtaining…. F and M suggest…for example….

--------------------------------------------------------------------


GWD-8-Q4 :

According to the passage, Frazier and Mosteller believe which of the following about medical research?

A.      It is seriously flawed as presently conducted because researchers overlook facts that are relevant to the subject of their research.

B.      It tends to benefit certain subgroups of patients disproportionately.

C.      It routinely reveals new variables in research on entirely new treatments.

D.      It can be made more accurate by limiting the amount of information researchers collect.

E.       It cannot be freed of the risk that significant variables may be overlooked.

???问题分析:FM对医学研究的看法。记忆中FM提出了新的方法。选项中提出建设性意见的只有D。而E选项是有关于新建议的一个风险分析,并不是看法的重点。

------------------------------------------------------------------

GWD-8-Q5 :

The author mentions patients’ ages(line 40) primarily in order to

A.      identify the most critical variable differentiating subgroups of patients

B.      cast doubt on the advisability of implementing Frazier and Mosteller’s proposals about medical research

C.      indicate why progressive diseases may require different treatments at different stages

D.      illustrate a point about the value of enrolling a wide range of patients in clinical trials

E.       substantiate an argument about the problems inherent in enrolling large numbers of patients in clinical trials

-------------------------------------------------------------------

GWD-8-Q6 :

The passage is primarily concerned with

A.      identifying two practices in medical research that may affect the accuracy of clinical trials

B.      describing aspects of medical research that tend to drive up costs

C.      evaluating an analysis of certain shortcomings of current medical research practices

D.      describing proposed changes to the ways in which clinical trials are conducted

E.       explaining how medical researchers have traditionally conducted clinical trials and how such trials are likely to change

问题分析:选择文章的中心思想,中心就是对原研究方法的改进。

GWD-8-Q7-Q10

      

      The system of patent-granting, which confers temporary monopolies for the exploitation of new technologies, was originally established as an incentive to the pursuit of risky new ideas. Yet studies of the most patent-conscious business of all—the semiconductor industry—suggest that firms do not necessarily become more innovative as they increase their patenting activity. Ziedonis and Hall, for example, found that investment in research and development (a reasonable proxy for innovation) did not substantially increase between 1982 and 1992, the industry’s most feverish period of patenting. Instead, semiconductor firms simply squeezed more patents out of existing research and development expenditures. Moreover, Ziedonis and Hall found that as patenting activity at semiconductor firms increased in the 1980’s, the consensus among industry employees was that the average quality of their firms’ patents declined. Though patent quality is a difficult notion to measure, the number of times a patent is cited in the technical literature is a reasonable yardstick, and citations per semiconductor patent did decline during the 1980’s. This decline in quality may be related to changes in the way semiconductor firms managed their patenting process: rather than patenting to win exclusive rights to a valuable new technology, patents were filed more for strategic purposes, to be used as bargaining chips to ward off infringement suites or as a means to block competitors’ products.

这一段,首先是提出专利权的一些东西,后来说这些东西对于半导体公司不实用。然后以一个年代段为例说明这个问题。
            

------------------------------------------------------------------


GWD-8-Q7 :
            

The passage is primarily concerned with discussing

A.      a study suggesting that the semiconductor industry’s approach to patenting during the period from 1982 to 1992 yielded unanticipated results

B.      a study of the semiconductor industry during the period from 1982 to 1992 that advocates certain changes in the industry’s management of the patenting process

C.      the connection between patenting and innovation in the semiconductor industry during the period from 1982 to 1992

D.      reasons that investment in research and development in the semiconductor industry did not increase significantly during the period from 1982 to 1992

E.       certain factors that made the period from 1982 to 1992 a time of intense patenting activity in the semiconductor industry

问题分析:文章的主旨。感觉是专利权有没有起作用的一个争论。当然做题只觉得1982-1992只是一个例子,没想到所有选项这个时间都是论述的主要点。
            

--------------------------------------------------------------------

GWD-8-Q8 :
            

The passage suggests which of the following about patenting in the semiconductor industry during the period from 1982 to 1992 ?

A.      The declining number of citations per semiconductor patent in the technical literature undermines the notion that patenting activity increased during this period.

B.      A decline in patent quality forced firms to change the way they managed the patenting process.

C.      Increased efficiencies allowed firms to derive more patents from existing research and development expenditures.

D.      Firms’ emphasis on filing patents for strategic purposes may have contributed to a decline in patent quality.

E.       Firms’ attempts to derive more patents from existing research and development expenditures may have contributed to a decline in infringement suites.

GWD-8-Q25-Q28

      Jon Clark’s study of the effect of the modernization of a telephone exchange on exchange maintenance work and workers is a solid contribution to a debate that encompasses two lively issues in the history and socialogy of technology: technological determinism and social constructivism. Clark makes the point that the characteristics of a technology have a decisive influence on job skills and work organization. Put more strongly, technology can be a primary determinant of social and managerial organization. Clark believes this possibility has been obscured by the recent sociological fashion, exemplified by Braverman’s analysis, that emphasizes the way machinery reflects social choices. For Braverman, the shape of a technological system is subordinate to the manager’s desire to wrest control of the labor process from the workers. Technological change is construed as the outcome of negotiations among interested parties who seek to incorporate their own interests into the design and configuration of the machinery. This position represents the new mainstream called social constructivism.

      The constructivists gain acceptance by misrepresenting technological determinism: technological determinists are supposed to believe, for example, that machinery imposes appropriate forms of order on society. The alternative to constructivism, in other words, is to view technology as existing outside society, capable of directly influencing skills and work organization. Clark refutes the extremes of the constructivists by both theoretical and empirical arguments. Theoretically he defines “technology” in terms of relationships between social and technical variables. Attempts to reduce the meaning of technology to cold, hard metal are bound to fail, for machinery is just scrap unless it is organized functionally and supported by appropriate systems of operation and maintenance. At the empirical level Clark shows how a change at the telephone exchange from maintenance-intensive electromechanical switches to semi-electronic switching systems altered work tasks, skills, training opportunities, administration, and organization of workers. Some changes Clark attriutes to the particular way management and labor unions negotiated the introduction of the technology, whereas others are seen as arising from the capabilities and nature of the technology itself. Thus Clark helps answer the question: “When is social choice decisive and when are the concrete characteristics of technology more important?”
                

文章分析:开篇指出clark的研究对于技术决定论和社会构造论的影响的决定有重要意义,并且clark是通过电话这一科技影响来说明他的观点的。第一段然后说明了科技决定论的一些东西。这里科技论受到的挑战主要来自于B这个人。
                

第二段,承第一段篇末留下的对比,说明社会论是对科技论错误理解后的产物。Clark在理论和实证两个方面说明了社会论与科技论的区别联系。
                

 理解方面不到位的地方是:没理解clark对于社会论与科技论的主要态度和立场。
                

借鉴网上给出逻辑简图:
                

JC’s study is a solid contribution to debate two issues: technological determinism and social constructivism. C decisive evidence… C believes obscured; exemplified….. C refutes the extreme… Thus, C helps answer….

GWD-8-Q25 :
            

The primary purpose of the passage is to

A.      advocate a more positive attitude toward technological change

B.      discuss the implications for employees of the modernization of a telephone exchange

C.      consider a successful challenge to the constructivist view of technological change

D.      challenge the position of advocates of technological determinism

E.       suggest that the social causes of technological change should be studied in real situations

问题分析:文章的主旨。应该就是C对科技与社会的理解分析。由此可以排掉BDE,第二段C用理论和实证来challenge社会论。而A选中more positive并没有相关比较。
                

--------------------------------------------------------------------

GWD-8-Q26 :
            

The information in the passage suggests that Clark believes that which of the following would be true if social constructivism had not gained widespread acceptance?

A.      Businesses would be more likely to modernize without considering the social consequences of their actions.

B.      There would be greater understanding of the role played by technology in producing social change.

C.      Businesses would be less likely to understand the attitudes of employees affected by modernization.

D.      Modernization would have occurred at a slower rate.

E.       Technology would have played a greater part in determining the role of business in society.

问题分析:would be是一个虚拟时,就是在文章并没有原文论述题中的情况。关键词是acceptancesocial constructivism。第一段最后和第二段开始有说到。C认为社会论的接受是一个错误,所以答案应该是一个积极的反应。所以排CD
                

--------------------------------------------------------------------

GWD-8-Q27 :
            

The author of the passage uses the expression “are supposed to” in lines 34-35 primarily in order to

A.      suggest that a contention made by constructivists regarding determinists is Inaccurate

B.      define the generally accepted position of determinists regarding the implementation of technology

C.      engage in speculation about the motivations of determinists

D.      lend support to a comment critical of the position of determinists

E.       contrast the historical position of determinists with their position regarding the exchange modernization

问题分析:are supposed to 是一个带有虚拟语气的短语,这里是说作用,那么应该与前句有关,看它对前句产生什么影响:这里的作用其实是更正。
                

--------------------------------------------------------------------

GWD-8-Q28 :
            

Which of the following statements about the modernization of the telephone exchange is supported by information in the passage?

GWD-8-Q35-Q37

This passage was adapted from an article written in 1990.

     Research data indicate that there is a great deal of poverty in the United States among single-parent families headed by women. This problem could result from the fact that women’s wages are only 60 percent of men’s. Some economists believe that rigorous enforcement of existing equal pay laws would substantially decrease this wage inequity. But equal pay laws are ineffectual when women and men are concentrated in different occupations because such laws require only that women and men doing the same jobs be paid the same. Since gender concentration exists (for example, 80 percent of clerical workers are women), other economists argue that a comparable worth standard, which would mandate that women and men in any jobs that require comparable training and responsibility be paid the same, should be applied instead. But some policy analysts assert that, although comparable worth would virtually equalize male and female wages, many single-parent families headed by women would remain in poverty because many men earn wages that are below the poverty line. These policy analysts believe that the problem is not caused primarily by wage inequity but rather by low wages coupled with single parent hood, regardless of sex. As a solution, they challenge the government’s assumption that a family’s income should depend primarily on wages and urge the government to provide generous wage supplements (child and housing allowances) to single-parents whose wages are low.

文章分析:根据研究数据对单亲妇女的收入进行讨论。从经济学家认为是性别差异导致的收入差异,到最后得出只要是单亲家庭生活都挺苦的,与性别无关。
                

--------------------------------------------------------------------


 

GWD-8-Q35 :
            

The passage suggests that the United States government’s policy towards providing wage supplements to parents whose wages are low is

A.      considered ill advised by most economists who have studied the issue

B.      based on assumptions about the appropriate sources of family income

C.      under revision in response to criticism from some policy analysts

D.      capable of eliminating wage inequality but not of raising incomes for both women and men

E.       applicable to single-parent families headed by women but not to single-parent families headed by men

问题分析:文章的建议。应该是在文章最后才提出了最终的建议。只根据单亲与否不根据性别。所以应该选B

--------------------------------------------------------------------

GWD-8-Q36:
            

Which of the following is most clearly an example of the policy advocated by the policy analysts mentioned in line 26 ?

A.      A government provides training to women who wish to move out of occupations in which women are concentrated.

B.      A government supports research that analyzes the connection between wage inequality and poverty among single-parent families headed by women.

C.      A government surveys wages annually to make certain that women and men in the same jobs receive the same pay.

D.      A government analyzes jobs in terms of the education and responsibility they require and publishes a list of jobs that should be considered equivalent for wage purposes.

E.       A government provides large rent subsidies to single parents whose wages are less than half the average worker’s wage.

问题分析:L26里的政策分析所支持的。这时应该先看L26,这里就是说平等收入了也解决不了问题。那么这里有性别工资平等的选项要先被排除即ABC,另外D中还是一个工资平等问题所以也错。
                

--------------------------------------------------------------------

GWD-8-Q37:
            

According to the passage, some economists believe that, in the United States, there would be smaller differences between the wages of women and men who do the same jobs if

A.      equal pay laws were enforced more fully

B.      more stringent equal pay laws were passed

C.      a more rigorous comparable worth standard



 

    were developed and applied

D.      more men entered the occupations in which women are concentrated

E.       women received the same kind and amount of job training that men receive

???问题分析:在什么情况下男女工资就会平等,这个应该是前段的内容,一个可比的标准,保证教育训练相同的职位男女工次一样,要实施。这题的问题在于,some economists是文中所提到的哪些人?
