第二段说researches 拒绝了abc三种解释，然后又提出一种plausible explanation。这种情况，作者想强调的很明显就是最后一个explanation，所以A：present several explanations错误（只有一个plausible explanation）。
文中真实目的是such thorough carcass consumption implies 很好地对应了选项的Implication。【转】错选A，因为觉得整篇文章都在说这个finding的可能的解释，文章提出了唯有一个可能的解释，所以several错误。文章最后部分给出结论： Such thorough carcass consumption implies to the researchers either that········这表明了文章的目的不在于finding的explanation，而在于研究的含义。→这常常是主旨题的一个技巧，文章中最高频率提及的词不一定就是文章的主旨，这篇文章我没找到明确的转折点，但它有明确的结论：由转折点或者结论判断文章主旨。
错选(C) even as所表达的含义与原句不同，even as是“正当，恰好在…时候”，有at the same time的意思，而原句表达的是让步转折含义;将原句定语从句内容fairy tales that…改变为句子谓语’s fairy tales have been…，改变原句强调重心。(E) 正确，although引导让步状语从句，其主语是Han Christian Andersen，谓语是wrote，宾语是由that引导的从语从句所修饰的名词fairy tales;整个句子的主语是his plays, novels, poems, and travel books，系动词是remain。【AE】AE这就是限定性定语从句与非限定性定语从句的区别，这就话的主要意思就是啥出名啥不出名，如果用了非限定性，那就说这个定语从句可以去掉不影响句子，但是不可以啊，这就把句子的重点给去掉了
【转载】RON： if "with ____" is modifying xxxxx, then it should be describing some aspect, or sub-component, of xxxxx.【with表示某物的一部分】 here, "each" = each style of cooking. we can't use "with each style of cooking..." to describe "styles of cooking".【此处不能说styles的一部分，所以不能用with】。注意，each在此题是代词，找到代表的内容
定位在“Some individual firms in developing countries have raised their productivity but kept their wages (which are influenced by average productivity in the country's economy) low. ”。员工的工资是受国家经济的平均产量的影响的。并不是只受到自己的产量影响。所以选D，错选C原文是说有影响，选项说没影响
第一段说了陆栖蛇有adaptation，第二段用一个例子说了和水栖蛇相比，陆栖蛇的adaptation是个什么情况，第三段才正式介绍这个adaptation是什么.
正确B选项：The problem confronting terrestrial snakes is best illustrated by what happens to sea snakes when removed from their supportive medium.
C选项：文中没提到：effectiveness of an organism's adaptation; only 极端词；【尽量避免极端词！！】
错选D选项：文中只提到物种适应不同环境，没提适应相同的环境；
MGMAT says that as can also appear with a phrase, rather than a full clause when as clause acts as a modifier.
However, there is no comma in C and thus “as in most other developed countries” has to be read not as a modifier but as a part of comparison as trying to convey. But for proper comparison we need a verb and E gives us that lacking “they did”, avoiding the mistake made by C. Therefore, C is incorrect not for ambiguity but for wrong structure.
平行关系it was ... that ... and it was ... that ...错选B，时态错误，won praise应该发生在后面，不能用had done。B uses past perfect incorrectly (simple past for "it was only after" and past perfect for "it had won high praise" which comes later chronologically than when KG became publisher)
1.show that 后面跟一个完整句子，错选D，不是完整句子。而且 countries who也不正确。ABC错在 in people的说法上！！！
RON:
as noted in the post above -- choices a, b, c say "in these people, they consume..."
taken literally, this construction suggests that someone located inside these people is consuming nutrients.
