9.28北京760少量双钩(9.28晚小更新)

作文

AI: A powerful business leader has far more opportunity to influence a community or a nation than does a government official

AA: The business department of Apogee Company determines that since Apogee Company had a better profitability when it had only one location of office, it should close all branch offices and centralize its operations in one location now to improve the profitability by cutting costs and keep all employees under monitoring.

数学：

1.DS 一个长方形的油画，长24宽16，外套一油画框，套后仍为长方形，画框各处宽度相等，求画框宽度

(1)油画和画框面积之和为884

(2)画框面积为500

选D

2.PS 一个不规则五边形，内接在一个圆里，ABCDE五个顶点连成的线段中，AC是圆内一条直径，所对角为角B，求其他四个角的和，答案应该是180*(5-2)-90=450

3.DS热狗题:一男一女两人买热狗和饮料，两人所买各热狗的单价相同，各饮料的单价也相同，但热狗和饮料的单价未必相同。求热狗单价

(1)男共花19元

(2)女共花12元

我选E

4.DS: AB同时从100米高处落下，B比A晚10秒开始下落，问AB谁先落地

(1)B的速度比A快1米/秒

(2)B的速度比A快25%

选C

逻辑

1.A与B争论一问题，A说官员不应对违反法律的现象熟视无睹，cracking down lawbreakers will be beneficial to our society.

B说其实大部分被违反的法律都是outdated的，如果repeal所有的outdated laws，会花费很多时间和金钱

问题是两人讨论的issue是什么？

两个比较靠谱的答案是

(1) Whether cracking down lawbreakers is beneficial to society.

(2) official's motivation for not cracking down lawbreakers is benign.

2.遇到了新火车代替旧火车的题，但是国家铁路限速是80的那道题，我读题后觉得比较确定是选新车的维修频率低，因此花在维修上的时间短。供参考。

3.题干讲了半天投资股票和投资债券的区别，大意是投资股票风险高收益也高，但是由于brokers劝说投资者买债券的话，他们自己可以收到更多的手续费。问这个观点以哪个选项为前提，我选的是最后一个，at least some brokers为了自己多赚钱而建议投资者买债券。

4.Diagnosis of drivers who incurred fatal car accidents reveals that among those drivers under 50 with fatal accidents, 5% are diganosed to have P**(一种眼部疾病). This disease affects peripheral vision. However among entire population under 50, only 3% are diagnosed to be infected with P**. Therefore it is the P** disease that has led to drivers' fatal accidents.

A. Many patients with P** in later stage cannot drive because their sights are seriously hurt.

B. Diagnosis of P** requires use of a kind of test. However it's unlikely that people under 50 will take this test.

C. Although P** is considered to happen more often among ppl over 50, some younger ppl, who are in their 30s and 40s, are also infected with it.

D. Except from impact on peripheral vision, P** does not have impacts on other vision abilities.

大意是这样，我选的第一个，但是不确定。

语法

有sth's metabolism is more like the mammal's than the cold-blood reptile's那道，好像之前有人总结了是GWD原题吧。。。

阅读

3篇双钩，分别是加州华人，价格策略，还有一篇犁地的。有一篇新的是关于Study of African American的，讲192*年以前这方面的study集中在南部的黑人上，因为当时80%的黑人都住在南部；之后呢有一个黑人的migration from southern American to northern american，从此之后这方面的研究就转向对northern African American urbanization的研究和对southern African American与southern White American之间的关系的研究。然后作者就说呢，对southern African American与southern White American之间的关系的研究其实是对southern African American不全面的研究，因为southern African American自己这个community也有很大变化，也很值得研究的。

题一：192*年之前对African American的研究为何集中在对southern African American的研究上？

答案：因为学者们chose a region with most African American population

题二：After 192* the scholars who studied southern African American failed to provide a sufficient study in that they____

Answer: failed to regard the improvement in southern African American community itself as important as the relationship b/w southern African American and southern White American

题三：What's the purpose of the passage?

Answer: To introduce and evaluate the study on African American (大致意思)

其他的我再努力回忆一下。。。

先顶后看，谢谢楼主，祝申请顺利~ 

阅读提到的最后一篇，怎么特别像OG中的一篇？

OG上是说就业的，听LZ描述感觉还不太一样

请楼主确认一下是寂静里面的这一篇么：

关于W.E.B. Du Bois就是gwd里出现过的那个黑人，但绝非是gwd里的那篇

共两段，第一段说他先有一篇文章（或是一本书）说他认为研究黑人种族问题和白人问题不同，他要求黑人问题研究者不要把自己的个人经历融入到研究中

第二段说他后来发现这样做会导致缺乏empirical evidence
