运气真是太好了，竟然能报到换库第一天，心疼下今天一起考试的小伙伴们和自己，被数学虐到体无完肤，最后Q49 V40，数学不好，所以就不误导大家了，尽量回忆一下题目
数学：
DS：给了一个图，见附件中，问题：AB是直径吗？
（1）AO＝BO；（2）BO=CO
DS：a<10，求a＝？
（1）a有4个因子
（2）忘记了
语法：
1.考了ensurethat someone be appointed to 某个职位
ensurethat someone be appointed 某个职位
ensurethat someone appointed to 某个职位
2.考了ifmore so的用法
3.考了eventhough作为subodinator，不用加连词的用法
整体句子很短，划线部分只有一两句比较长，大部分还好，相信大家都能斩杀SC！
作文：一个gourmetgrocery的manager说最近销售额下滑，为了增加profits，他决定要cut cost，背景：光临这个店的都是wealthycustomers；plan：1、lay off 10 employees and reduce expensive displays and freesamples to cut costs ；2、to offset the bad effects of such an elimination,partner with a nearby Coffee Café，这个café的顾客群体和grocery的顾客群体是一致的，所以在这个café增加smallcoffee counter来卖自己的产品，可以尽可能吸引new customers

一、考到了和OG2018其中一篇阅读背景知识类似的文章，讲的是firstinvertebrate的历史。
过去的生物学家都认为原始生物是从海洋生物进化而来的，随着研究的深入，发现有化石显示原始生物不仅有从海洋中进化而来的，还有从E（大概是介于海洋和淡水中间的一种水域吧）和淡水中进化而来的。
一方面，科学家们承认淡水中营养缺乏是不能单独作为生物发源的地点，一方面科学家们认为淡水也有其独特的优势：即safe和更少的predators
研究发现，有一种生物O，它从海洋中移居到了E，在这里它开始developspecial characteristics to adapt to fresh water，最后生物开始在淡水繁衍
这篇文章比较长，6段左右，虽然很多专业名词，但是不难理解
二、foreigninvestment在wealthy countries和poor countries之间的差别
传统的观点认为developingcountries 因为投资机会比较多，return比较高，所以foreign investment会倾向于流入这些国家；但是实际上正好相反，反而是poorcountries invest more into developed market
原因是：poorcountries的financial market/system不够发达，所以虽然人们的income增长很快，但是人们没有把它用去放贷，而是转而投向wealthycountries，因为这些国家的金融体系更加发达。
本篇文章很短，仅两段，考察的都是对整个理论的理解
对不住大家，逻辑我真是一道也想不起来。

最后祝大家沙棘成功！也祝我自己三战越战越勇！

小呀么小橙砸

找到一篇关于Jupiter的 ：
ugust 22, 1676: Rømer Waits for the Speed of Light
Jupiter’s moon Io with Jupiter in the background, photographed by the Voyager 1 spacecraft on March 2, 1979. The cloud bands of Jupiter provide a sharp contrast to the solid, volcanically active surface of its innermost large satellite.

One of Jupiter’s moons, Io, led the Danish astronomer Ole Rømer to the first measurement of the speed of light in 1676. Rømer spent time observing the movement of Io and Jupiter’s other satellites and compiling timetables of their orbital periods (the time it takes for the moons to revolve around Jupiter once). Io’s orbital period was observed to be 1.769 Earth days. The key phenomenon that Rømer observed was that the time elapsed in between eclipses was not constant. Rather, it varied slightly at different times of year. Since he was fairly confident that the orbital period of Io was not actually changing, he deduced that this was an observational effect. The orbital paths of Earth and Jupiter being available to him, he noticed that periods in which Earth and Jupiter were moving away from each other always corresponded to a longer interval in between eclipses. Conversely, the times when Earth and Jupiter were moving closer together were always accompanied by a decrease in the eclipse interval. This, Rømer reasoned, could be satisfactorily explained if light possessed a finite speed, which he went on to calculate.                                             

Rømer was so dedicated in his studies that he continued tracking and timing Io’s orbital period for years, discovering a very interesting phenomenon as a result. Because Rømer was observing Io’s orbit throughout the year, he was recording data as Earth and Jupiter moved farther apart and closer to each other as they themselves orbited the Sun. What he discovered was a 17-minute delay in a usually clockwork eclipse of Io that occurred when Earth and Jupiter were farther away from each other. Rømer knew that Io’s orbital period couldn’t be changing just because of the distance between Earth and Jupiter, so he developed a theory: if only the distance between the planets was changing, the image of Io’s eclipse must be taking those 17 extra minutes to reach our eyes on Earth. This theory of Rømer’s was rooted in another: that light moved at a fixed speed. Rømer was able to use rough calculations of Earth’s diameter and the time delay from Jupiter to come up with a speed of light that was fairly close to the actual adopted value.
