6. perimeter of a equilateral triangle T和perimeter of a square R是否相等。
(1) a side of T of
(2) the ratio: T and R=4:3
7.花费65mil投资一个年利率12％的项目, 单利. 问要增加多少年收益可以达到10mil.
8.
A的工作效率是否超过12k每小时?
(1)A的效率>2g每秒；（2）A的效率<5g每秒 (k、g是单位，1k＝1000g，我选E)
9.这个题目是费费原来题目, 但数字变了, 大家注意不要背诵答案:
一直线L过点A(5,0)，B(0,10)，坐标原点为O，点P(x,y)为三角形OAB中的一点，问：y<x的概率为多少？
【思路】面积求法：直线y=x交AB于C（10/3，10/3）,将三角形AOB分为两个三角形，三角形OCA中个点都满足Y<X所以所求概率=OCA的面积/OAB的面积
10.大人是小孩的三倍，女人是男人的2倍，小孩，男人，女人一共是x个，问男人是多少个？
答案: x /4
11. 问k和l是否垂直:
(1) k和l在y轴上intercept为2
(2) k在x轴上intercept为2, l在x轴上intercept为-2 (好像是这样的..)
12. (mq+np)/pq是整数, must be true?
I. m/p为整数
II. np/pq是整数
III. p^2/mn (不确定)
13. 好像还有一个开根号sqrt的题目, 但和JJ不太一样…

32. The following appeared in the editorial section of a West Cambria newspaper.
“A recent review of the West Cambria volunteer ambulance service revealed a longer average response time to accidents than was reported by a commercial ambulance squad located in East Cambria. In order to provide better patient care for accident victims and to raise revenue for our town by collecting service fees for ambulance use, we should disband解散, 裁减our volunteer service and hire a commercial ambulance service.”

5. “All groups and organizations should function as teams in which everyone makes decisions and shares responsibilities and duties. Giving one person central authority and responsibility for a project or task is not an effective way to get work done.”

第一篇: 前人的15-19日JJ总结
1.美国黑人在new york的在17xx-18xx的生活状况
大概是说一直以来历史学家认为纽约的黑人生活状况比较好，但是一个叫white的人的研究认为不是这样的，说new york的黑人待遇不比别的地方好，论据是，虽然纽约的free的黑人 increased, however, slavery 其实也增加了，并且无论wealthy white,还是white artison（工匠）
都有黑人奴隶，而其前的研究认为white artisan 是倾向越黑人工人和白人工人
但是作者又说，white的研究在某些方面不对，好像是关于黑人community类的，说有很多黑人的church. 然后最后一段作者又说如果white说研究的时间能够延长到1830年会更好
2.
纽约黑人的问题。第一段，很多科学家都认为17-18世纪，纽约的黑人都生活的比较好，因为纽通过了废除黑奴的法律，而美国其他州没有。（有题目）
然后说，有个学者否定这个观点，认为纽约黑人的生活并不好。
第二段，说这个学者的观点，因为学者提出了纽约虽然free的黑人增加了，但同时美国的黑奴也增加了。而且纽约的有钱人，和artisan，也雇用了黑奴（egalitarian是个关键词，考点）。
第三段，说这个学者的观点片面了，如果能考虑1813的什么事件，并且把研究时间推到1830年会更好。
题目，1，主题，2，问artisan的，文章中说artisan被普遍认为是egalitarian，而这个学者的调查说明了他们并非是egalitarian，问的是这个学者之前的人怎么看artisan
第二篇: 前人的15-19日JJ总结
恐龙冷热血的讨论，两种观点，一个说恐龙是温血的，因为他们的骨骼很类似温血动物的，一个反对，作了一个试验，总结说是因为activity 而形成了这样的骨骼。题目有问主旨，
还有问两个观点的不同。
少量补充:
第一段: 提出观点:一个说恐龙是温血的，因为他们的骨骼很类似温血动物的
第二段: 做试验反对, 通过比较活动的(activity)的热血动物和冷血动物, 观察他们的骨骼, 说明是activity造成的骨骼区别
问题: 1. 主旨题目, 2.题目忘了, 答案就是第二段段意
还有一篇类似JJ的, 失忆…让我再想象再发

8. GWD-29-Q40
Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream. However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur. These results provide support for researchers’ prediction that naltrexone will turn out to be toxic to certain types of bacteria.
Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction?
A. After being administered to mice, naltrexone does not pass from the bloodstream into the intestine.
B. Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream.
C. Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance.
D. The increased risk of blood poisoning is not the only harmful effect on mice of being given morphine.
E. Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice
