作文：

The following appeared as part of an annual report sent to stockholdersby Olympic Foods, a processor of frozen foods.

“Over time, the costs of processing go down because as organizationslearn how to do things better, they become more efficient. In color filmprocessing, for example, the cost of a 3-by-5-inch print fell from 50 cents forfive-day service in 1970 to 20 cents for one-day service in 1984. The sameprinciple applies to the processing of food. And since Olympic Foods will sooncelebrate its twenty-fifth birthday, we can expect that our long experiencewill enable us to minimize costs and thus maximize profits.”

数学：

1. 一个六位数54xy12（有点记不得万位是不是4了，5和12确定），xy可以是3，5，8中任意一个数，x和y可以是同一个数，问能被8整除的概率（也有可能是不能被8整除的概率，大家考试的时候仔细看题哈）

2. 长方形A的长a宽b，长方形B的长c宽d，a/c=b/d=3/2, 问面积比

3. 圆在xy平面上，圆心在原点，半径过（3，0），问线L是否与圆intersect。
（1）点（2，2）是L上一点
（2）点（4，4）是L上一点

4. 5-根号5<根号x<5+根号5，x是正整数，求x：
1）有点失忆，应该是x是基数/偶数中的一个
2）根号x是一个整数的平方

5. 太阳系外a星距地球1000000000000km，月亮距地球10000km，问地图上月亮和地球的举例是1cm，那a星距地球多少km。（大概是这个意思，数字是我编编的，只记得a到地球的距离是月亮到地球距离的100000000倍，注意最后是问km不是cm，答案我选的1000


6. P=S（1+r/100)^(n)，n是年数，r是利率，S是本金，P是收入，问能否求出n年到（n+5）年之间的增长率
1）已知n
2）已知r

7.奖学金有3个级别1000，3500，9500，问总共94000的奖学金最少能分给几个得住。答案15

差不多都失忆，只能记得大概，希望能有助考古&启发别的构筑们
1. 某国受过专业培训的tailors和自己在家揽生意的妇女们的矛盾，tailors说妇女们抢走生意他们就没法养家糊口了要政府出政策规范市场，政府的立场好像是偏向妇女，因为根据以往的条例认为每个人都有权利sale自己的产品，买卖自由什么的，后面失忆了
2. 有一篇关于过去不同历史学家对黑人不同的关注点。开头是：和A，B不同的是，在XX时期（失忆好像是1970s的south）大多数历史学家并没有关注黑人经济方面（拥有多少土地，产业，商铺，是否wealthy）。下面列举一个时期的历史学家CDE的研究方向大致是黑人政治文化和人权发展。然后又说二战前后历史学家的关注点。最后又列举了F和G，说他俩的研究重点就是黑人如何发家致富的。
3. 讲美国1980s在国际市场的占有率比20年前要低，有些人认为是因为公司不愿意做longterm的研究和投资因为回报慢导致企业竞争力下降。然后作者就说有那要怎么解释同样是invest在长期的research的两个公司一个市场占有率上升一个下降呢？（有题，问为什么提到这两个公司）然后又举了些例子，结论是和每个公司内部决策安排有关。

逻辑和语法都记不得了，逻辑一大半都是如何weaken观点。

只求750

狗主辛苦~~~我觉得第一篇阅读主题和GWD上的一篇阅读有点像，求确认是不是这一篇~
In 1675, Louis XIV established the Parisian seamstresses’（女裁缝） guild（行会组织）, the first independent all-femaleguild created in over 200 years. Guild members could make and sell women’s and children’s clothing, but were prohibited from producing men’s clothing or dresses for court women. Tailorsresented the ascension of seamstresses to guild status; seamstresses, meanwhile, were impatient with the remaining restrictions on their right to clothe women.

  The conflict between the guilds was not purely economic, however.（关键的转这句，明细全文结构） A 1675 police report indicated that （第一方面）since so many seamstresses were already working illegally, the tailors were unlikely to suffer additional economic damage because of the seamstresses’ incorporation.Moreover,（第二方面） guild membership held very different meanings for tailors and seamstresses. To the tailors, their status as guild members overlapped with their role as heads of household, and entitled them to employ as seamstresses female family members who did not marry outside the trade. The seamstresses, however, viewed guild membership as a mark of independenc the patriarchal family.  Their guild was composed not of family units but of individual women who enjoyed unusual legal and economic privileges. At the conflict’s center was the issue of whether tailors’ female relatives should be identified as family members protected by the tailors’ guild or as individuals under the jurisdiction of the seamstresses’ guild.

Q3. A

第四题我选的B，因为根号下x可能等于3，4，5，6，7其中一个，只有等于4的时候才是一个整数的平方。

是我错了，我当成"x是一个完全平方数了"。寂静中的答案是正确的
