一点机经，一点感想。希望对大家有用。
先上机经
AI B1 | The primarily responsibility of citizen is to obey the nation’s civil and criminal law. |

124. The following appeared in a memorandum from the owner of Carlo’s Clothing to the staff. “Since Disc Depot, the music store on the next block, began a new radio advertising campaign last year, its business has grown dramatically, as evidenced by the large increase in foot traffic into the store. While the Disc Depot’s owners have apparently become wealthy enough to retire, profits at Carlo’s Clothing have remained stagnant for the past three years. In order to boost our sales and profits, we should therefore switch from newspaper advertising to frequent radio advertisements like those for Disc Depot.”
数学遇到几道机经，有机会大家还是要好好看。尤其是最好能把答案记住。我这次数学没有满分的原因就是没有记答案，实战中浪费了很多宝贵的时间。如果看JJ能把答案记住的话会有更多时间来做那些新题难题。我觉得考试的时候脑子远没有平时清醒，问题很难想的那么周到。建议大家把数学JJ一定要搞懂，另外就是数学如果想拿满分的话，不是那么容易。
1. 一道新题，说得很复杂，最终就是告诉你V=2W 求
(V+W)/(V/10+W/20 ) .数字可能不对，但是理解了前面话的意思，做起来很简单。
2. 一个厨师买面粉玉米小麦2种，告诉你总的面粉重量，告诉你面粉混合以后的价格，问你买了多少小麦面粉？
A．
告诉你小麦玉米的比例。
B. 告诉你二者各自的价格。
我选了D。
3. [x] is the least integer that is equal or greater than X, if [x]=0, what is the range of x? 我选-1<x<=0 4． 很多人遇到的9边形对角线条数问题， 9*6/2=27 5. 5个整数，其平均值比最小的整数大0.6，问这5个整数中最多可能有几个奇数？
A. 1
B. 2
C. 3
D. 4
E. 5 假设这5个整数是a,b,c,d,e 所以我们可以根据条件得出
4a = 3 + b + c + d + e 4a为偶数，3 + 奇数 = 偶数
所以 b+c+d+e=奇数，所以 b,c,d,e中最多可以又3个奇数，而a也可以为奇数，所以最多有4个奇数
所以是D
6. 一个圆，做一条与直径平行的弦长AB，长度等于半径，弦的2个端点与圆点连接形成一个等边三角形OAB。同时弦的2个端点做垂线与直径相交C，D二点，求三角形OCA的面积。
My key: 根号3乘以r的平方再除以8（对不起，不会打根号）
7. 另外一到常见JJ 有一道转盘题，转换成数学模型就是从1到8的整数中任选3个，记顺序，加起来等于16的有多少中情况。
（补充版本）图形题，一个圆盘，分成1～8八个区间，中间一个指针。问指针转动3次所得数字的和等于16的次数是多少？
42 把有重复和无重复的分开算。比如(8,4,4)把它算成P（3，3）是错误的。
8,7,1 8,6,2 8,5,3 3*P(3,3)
8,4,4 1*3
7,7,2 1*3
7,6,3 7,5,4 2*P(3,3)
6,5,5 6,6,4 2*3
数学能想起来的就这些。

GWD-29-Q17
The total market value of real estate in Altonville has steadily declined over the past four years. This decline has meant that the overall figure on which the city’s property tax is based—the assessed value of that real estate—has also declined. The percentage of assessed value that was paid as property taxes to the city, however, did not change from year to year during this period. The information above most strongly supports which of the following? A. The percentage of Altonville’s yearly revenue that comes from money collected in property taxes did not change over the past four years. 那只能比例也降低
B. The percentage of Altonville’s yearly revenue that comes from money collected in property taxes has declined steadily over the past four years.
C. The amount of revenue that Altonville collected from property taxes was lower la st year than it was four years ago.
D. During the past four years, Altonville officials increased tax rates on other source s of revenue such as retail sales and business profits.
E. Altonville will soon require property owners to pay a higher percentage of the as sessed value of their property as property tax.
Answer: C
还有一道是完成填空。大意是说某个地方现在经济发展不错，政府领导说了，现在这个经济形势下是实行一个什么整改措施的最好时机。那个措施不能在经济萧条时期进行，因为--------- 我选了因为这个措施会影响经济发展
还有一个什么杀虫药，做了试验，效果很好，这个药厂就说了，我们这个药很好，要大力推广。问你如何削弱？我预测的答案是其他原因引起，和他的杀虫药没有关系。花了大概6，7分钟愣没有找出来。最后选了个提到什么杀虫药，什么这个公司的选项。自此方寸大乱，在遇到逻辑题就看不懂了，开始瞎选了。建议大家如果不在前十道题的话超过3分钟坚决放弃。我就是被这道题打乱pace，后面很难再保持前面那种心态和节奏了。平时我做GWD，prep我逻辑基本不错，或者最多就错一个。此题以后做题时一点感觉都没有了，只考了这么一点分数
应该就死在逻辑上了。
SC T-7-Q41
Scientists have dated sharp-edged flakes of stone found in the fine-grained sediments of a dry riverbed in the Afar region of Ethiopia to between 2.52 and 2.60 million years ago, pushing back by more than 150,000 years the earliest date when it is known that humans made stone tools. - when it is known that humans made
- at which it is known that humans had made
- at which humans are known to have made
- that humans are known to be making
- of humans who were known to make
A when做定语从句还是状语从句不清楚。 C the best D be making错 这里还有一个主要问题：A/B都没有指明when/at which是修饰从句中的it is known（知道“人类用石器”的时间）还是humans (had) made（人类用石器的时间）. 属修饰歧义错误。
其他还考了as用法，主谓一致，代词指代等问题，实在记不清楚了。总体感觉和prep很接近。
RC 简爱，
potter，
美国企业投资市场份额问题三篇JJ，
还有一个很长的，最后一篇就是美国学者研究双语环境（西班牙语，英语）与那些只说英语的学生的学习成绩对比研究。结论就是双语更好。文章一开始有一道细节定位题，大概是回答为什么要进行这项研究，因为西班牙语裔人口多了。文章结论里面有一句暴长的话，看文章就没有看懂。偏偏这里有一道考题，问你那个选项的情况，可以支持这个结论所说的情况。大家看仔细了。
终于考完了，非常感谢老婆，妈妈，和我儿子的支持。我属于老同志了，呵呵！
总的来说，还是有些失望。我做prep4次，成绩750，760，780，770。跟论坛的很多兄弟姐妹相反，人家是平时600多，实际7百几十分。真的很不好意思。总结来看，就是大家还是要重视pace，不要被一道题浪费太多时间，特别是在自己最有把握的部分（就如我的逻辑）。很可能一但最有把握部分的题没有做出来，对心里的那种打击绝对的大。大家引以为戒。
另外对阅读JJ的看法，除了对于特别详细的JJ外，我建议大家读文章以前，最好采用头脑空白原则。我实际考试过程中，发现因为是JJ文章，颇不急待的就去看答案了，结果没有JJ里描述的答案，再回答看文章的时候很难看进去了。而且这种情况下对心态影响很大，很难决定到底还要不要相信jj。我在最prep的时候。从来都是看文章，在做题。很稳当，遇到拿不准的回原文看一下就行了。以我失败的例子，给大家提个醒。
