SC，原本是我的强项啊，今天考到的感觉没啥语法点啊！ 最荒谬的一题是：If you blablabla（没仔细看）, please let me know and I would(and I would划线) prepare a copy（貌似）. 真的懵了，这破题在考什么啊！搞到我犹豫了，最后选了so I can。哎杯具...
P.S.特别感谢Pudgysphere，认识没多久但是很感激。你那句No matter what, tomorrow is another day是我们俩天涯沦落人的内心写照，搞到我不争气地猛掉眼泪。还有下午那句“你不是我，我没考好跟你没有任何关系~不要紧张，好好发挥~”，除了感动我不知道还能说什么。
frombluewoods 我遇到的otter-seal题事后对了一下狗狗（考前没怎么看CR的jj,因为一战看了好象有些反作用，每个人情况不一样当然），发现我的那道很奇怪，说的是otter会吃seal,而seal多了会常去beach导致beach遭到破坏，所以otter的存在保护了beach, 但是现在海面遭到了oil pollution导致otter大量死亡。问：Which of the following, if true, would serve to weaken the conclusion?
麻烦lz确认个哈哈谢谢 14.再见sea otter V1 from cytlc1978 sea otter那题，原题问weaken，我考的这道问support，题干略有变动，选项跟原题完全不同 V2 from xzbest otter数量下降，与此同时seal数目上升。Seal是被killer-whale吃的。说whale数目增加，又说seal怎样怎样，所以说otter是被whale吃了。问啥忘了。。 V3 from qq309790244 kill whale：seaotter数量减少。report说sealion 和seal也下降，killwhale吃sealion和seal，但是报告说killwhale吃seaotter is rare，但在1980前根本没有报告。所以seaotter下降是由于killwhale。问支持 GWD原题： GWD-8-Q3: In the late 1980’s, the population of sea otters in the North Pacific Ocean began to decline. Of the two plausible explanations for the decline—increased predation by killer whales or disease—disease is the more likely. After all, a concurrent sharp decline in the populations of seals and sea lions was almost certainly caused by a pollution-related disease, which could have spread to sea otters, whereas the population of killer whales did not change noticeably. Which of the following, if true, most seriously weakens the reasoning? Killer whales in the North Pacific usually prey on seals and sea lions but will, when this food source is scarce, seek out other prey. There is no indication that substantial numbers of sea otters migrated to other locations from the North Pacific in the 1980’s. Along the Pacific coast of North America in the 1980’s, sea otters were absent from many locations where they had been relatively common in former times. Following the decline in the population of the sea otters, there was an increase in the population of sea urchins, which are sea otters’ main food source. The North Pacific populations of seals and sea lions cover a wider geographic area than does the population of sea otters.
