7.23一战760回报cd放狗

Atropa

楼主运气超好中了四篇阅读分别是岛上遗骨，学习曲线，铺power line，海洋共有资源。虽然有些题有点难但我觉得看了机经还是要好很多。

作文是说辞去工作在家self-employed得人经常会被手机，噪音，家务转移注意力。他们会变得social and professional isolated，从而 less opportunities for career advancement.结论好象是sticking with office job would  have greater earnings。

数学也中了一些机经，比如倒放梯形算高的，几分几秒range的那个之类的。

有几个之前错误和待补充的机经说一下。
1.那个图片外面套border的题，是without boder的长是宽的两倍，然后without border的面积是196。
2.最小公倍数和最大公约数的题是12250与n的最小公倍数是24500，最大公约数是350。
3.然后什么french 之类的那个韦恩图我遇到的是求 只有两个language的人数。
4.直角梯形那道题字母好像标错了，图应该是下底边是AD，上底边是BC。P在bc上。题目是bc=cd，bc//ad，求abcd面积
条件1，dp=6，
条件2，ad=10

补充其他的数学题
1.DS 已知苹果比桔子贵0.1元，求昨天桔子的total revenue。
条件1，桔子比苹果多卖了5个。
条件2，苹果昨天的revenue是15（还是多少我忘记了）
2.DS b^2+1是否为5的倍数？
两个条件都是【一个含b和常数的表达式】是5的倍数。具体是b+什么我忘记了，反正可以写成b的通项式代回 b^2+1来。两个都可以证明是5的倍数。

IR
1.给了1月的investment on R 和CI，二月的investment on R和CI， 然后说investment on R 和investment on CI是线性关系，所以可以通过这两组数求表达式。我记得求出来是R=-0.8CI+一个什么数忘记了。然后问三月应该减少多少R，增加多少CI。 给了几组数，应该选25 20 的那一组。
2.有很多个projects 给出了它们success的概率，success的话会gain多少，fail的话会loss多少。
三个statement，第一个是说有个的fail的概率是最低的，很简单一眼就可以看到。
第二个说有个success的gain是最高的，也很简单。
第三个说F项目的expected gain是最高的，这个需要计算！是错的！
3.超市调查
有总调查人数一半的人【今天要purchase】，然后【今天要 purchase人数】超过一半的人【更prefer传统购物神马的】

大概就这么多了~如果我等会灵感突现会过来补哒~
最后说一下阅读机经大家最好自己把脉络理一遍特别是每个自然段的脉络，不要只看一下~这样考试的时候基本上看了开头就知道是讲什么并且在哪里定位了~biu~
大家加油~~~

对了之前考过的同学可不可以告诉楼主你们的unofficial report上是不是有什么authenticated code？？为什么我的没有？？

"What these new fossils are telling us is that the early species of our genus, Homo, were more distinctive than we thought. They differed not only in their faces and jaws, but in the rest of their bodies too," said Carol Ward, a professor of pathology and anatomical sciences in the MU School of Medicine. "The old depiction of linear evolution from ape to human with single steps in between is proving to be inaccurate. We are finding that evolution seemed to be experimenting with different human physical traits in different species before ending up with Homo sapiens."

Three early species belonging to the genus Homo have been identified prior to modern humans, or Homo sapiens. Homo rudolfensis and Homo habilis were the earliest versions, followed by Homo erectus and then Homo sapiens. Because the oldest erectus fossils that have been found are only 1.8 million years old, and have different bone structure than the new fossil, Ward and her research team conclude that the fossils they have discovered are either rudolfensis or habilis. Ward says these fossils show a diversity in the physical structures of human ancestors that has not been seen before.

"This new specimen has a hip joint like all other Homo species, but it also has a thinner pelvis and thighbone compared to Homo erectus," Ward said. "This doesn't necessarily mean that these early human ancestors moved or lived differently, but it does suggest that they were a distinct species that could have been identified not just from looking at their faces and jaws, but by seeing their body shapes as well. Our new fossils, along with the other new specimens reported over the past few weeks, tell us that the evolution of our genus goes back much earlier than we thought, and that many species and types of early humans coexisted for about a million years before our ancestors became the only Homo species left."

A small piece of the fossil femur was first discovered in 1980 at the Koobi Fora site in Kenya. Project co-investigator Meave Leakey returned to the site with her team in 2009 and uncovered the rest of the same femur and matching pelvis, proving that both fossils belonged to the same individual 1.9 million years ago.

嗨，楼主确认下好吗~~~
