从CD下载了prep2007和prep2008语法，加本月数学寂静。刚考完，赶紧把记得的倒出来回报CD。

AA：一经理说人家非盈利组织的员工都很motivated而且productivity很高，我们公司应该把盈利的一部份捐给人道组织，这样才能improve motivation and productivity.

数学：只记得两道我做错了的题。
第一道题（1）我算了很久也没算出答案。
（1）A电脑卖出的量是B电脑的3倍，A的利润是80%，B的利润是20%， 问总利润是多少？ 我用3/4乘80%加1/4乘20%得出65%但没这个答案。我要么算错了要么理解错了题意。
（2）DS。正方形A内切于圆B，圆B内切于另一个正方形C，问圆B的周长是否大于10。
--1， A的边长大于2
--2， C的边长大于4

英语：
只记得3篇作文。
（1）妇女准备食物这事儿一直没受到学者的重视，后来有个学者说这事儿挺值得研究。古代秘鲁的宴会食物都是妇女准备的，里面提到一个叫Root beer的食物。后来在准备另一种食物的时候，这种食物更耗时，但是比喻携带。让人们可以在离家更远的地方工作。
（2）争论纽西兰什么时候开始有人居住。一开始有科学家从老鼠的骨骼化验中推出在公元前200年就有人把老鼠带到了纽西兰。后来有科学家重新作了实验，推翻了以前的结论，说其实是从12世纪末才有人到纽西兰。然后最后一段说气候和生态变化的罪魁祸首要重新判定。 --补充，和楼下考古的那一篇很接近，但不完全一样
（3）讲了一个collateral screening的概念。说是成本比较低的小公司比较愿意用collatal向银行贷款。因为银行在贷款的时候会调查公司的成本，调查的费用是由贷款获得批准的公司支付的。那些成本比较高的大公司，它们的贷款向较于成本小的小公司比较难批准。这样这些小公司实际上帮大公司付了银行调查的费用。于是小公司用collateral 向银行贷款，这样贷款批准的时候它们就不用付银行调查的费用了。   --补充，就是楼下考古的那一篇

补充两个落籍：
（1）说某地冬天下雪比秋天猛，但是保险公司接到车辆被雪压的case秋天的多过冬天的，问原因。
有几个选项很让人九届，我选了应为常青树冬天可以承受更多雪的那一项，不一定对哈
（2）说美国一个医疗器械要能被医生采用必须先经过很严格的检测，只有跟1985年前Equivalent的可以免检，问原因。
我选了因为1985年前的检验标注比现在更严格那项。


最后祝本月考试的同学们Good  luck!

确定一下？
economist 有一个 hypothetical model, 内容主要说： when firms apply for a bank loan, 他们需要知道自己的operating costs,但是operating cost会被其他因素影响，因此还需要向bank 申请evaluation, bank要对他们进行investigation.

　 　higher cost firms不容易被approved,while low cost firm更容易被approved，那么high cost firms will be subsidisized by low cost firms. and the low cost firm knows that. 因此，to distinguish from the high cost firm, they will 跟银行弄一个collateral.而collateral 的风险成本很大，所以high cost firm基本上不会collateral，而low cost firm 因为本身low cost，不特别在乎其带来的风险. 所以到后来，就只有low cost firm 弄collateral(质押)，而且他们只要弄了collateral银行就基本上不会对他们进行eveluation.

　　问题好像有:

　　(1)银行只对批准贷款的公司作风险评估,为什么?

　　(2)high cost firms 在什么情况下会去做质押?

An international team of researchers, led by Dr Janet Wilmshurst from Landcare Research, spent 4 years on the project which shows conclusively that the earliest evidence for human colonisation is about 1280-1300 AD, and no earlier. They based their results on new radiocarbon dating of Pacific rat bones and rat-gnawed seeds. Their results do not support previous radiocarbon dating of Pacific rat bones which implied a much earlier human contact about 200 BC.
The original old rat bones dates have been hotly debated ever since they were published in Nature in 1996. The ages are controversial because there is no supporting ecological or archaeological evidence for the presence of kiore or humans until 1280-1300 AD and the reliability of the bone dating has been questioned. This is the first time that the actual sites involved in the original study have been re-excavated and analyzed.
Dr Wilmshurst and her team researchers re-excavated and re-dated bones from nearly all of the previously investigated sites. All of their new radiocarbon dates on kiore bones are no older than 1280 AD. This is consistent with other evidence from the oldest dated archaeological sites, Maori whakapapa, widespread forest clearance by fire and a decline in the population of marine and land-based fauna.
“As the Pacific rat or kiore cannot swim very far, it can only have arrived in New Zealand with people on board their canoes, either as cargo or stowaways. Therefore, the earliest evidence of the Pacific rat in New Zealand must indicate the arrival of people” Dr Wilmshurst said.
The dating of the rat bones was also supported by the dating of over a hundred woody seeds, many of which had distinctive tell-tale rat bite marks, preserved in peat and swamp sites from the North and South Islands.
“These rat-gnawed seeds provide strong additional evidence for the arrival of rats, and therefore humans, and are an indirect way of testing the veracity of the dates we have done on rat bones,” said Dr Tom Higham, Deputy Director of the Oxford Radiocarbon Accelerator Unit at Oxford University.
Rats leave rows of narrow grooves or bite marks on woody seed cases when they gnaw open the seed, and these distinctive teeth marks can be seen with the naked eye. “The width of the teeth marks left on the woody seeds exactly match those of a rat's two front teeth, and cannot be mistaken for any other seed predator. We have dated over 100 individual seeds, some rat-gnawed, others intact or bird-cracked, which show that rat gnawed seeds only occur in both the North and South Islands of New Zealand after about 1280 AD”, Dr Wilmshurst said.
With over 165 dates on seeds and bones from a large number of sites, the overwhelming evidence suggests that rats and their human carriers did not reach New Zealand until about 1280 AD.
这个和新西兰的那篇是原文吗
