第二句最后一句扭转了态度：Even within national contexts, studies have found more support for the density dependence model when they employ broader geographic units of analysis

1.主谓一致，排A
2.平行结构，排E
3.如果主语和谓语动词之间有插入的定语成分，要么用双逗号或者双破折号隔开（非限定性定语），要么均不用逗号隔开（限定性定语），排CD
4.逻辑：没有转折关系，排ACD

“But when the energy coming from the galactic center is compared to widely held predictions based on how much matter should be falling into a theoretical central black hole, there is a discrepancy by a factor of a few thousand.”说现在收到的energy比本应收到的少，A说现在假设的黑洞吃的太多，也就是说实际情况下黑洞吃的没这么多，吃的少那么放的能量就少，问题就没有了。

只有第一段最后一句提了一下而已。可是后面文章的反驳都没有提到了，这也算？那我就觉得D那个combination可以接受诶。

答案D至少是补充说明了，有例子证明左大脑有语言中枢的，stroke了以后会damage至少一边。

文章是在讲环境恶化吗？文章不是在讲amphibian的数量下降和灭绝吗？什么鬼啊。。。

1. idioms: try to do. b中try and recover逻辑上不平行，try uranium?不对，排除b。d中try for也不对，排除d
2. idioms: recover from. not "recover out of",排除c/d
剩下a/e, e中worthwhile to try就可以了，后面的to do有点redundant. sth may be worthwhile to try. try后面的宾语又是该句的主语，这就变成了“sth may be worthwhile to try sth“--> redundant.
最后剩下a.

Again, such simplifications and obscurities exist in order to give prominence to the depiction of sharply delineated moral values, values derived from a character’s purely personal sense of honor, rather than, as in a Jamesian novel, from the conventions of society.

Indeed, most twentieth-century commentators regard Melville not as a novelist but as a writer of romance, 这是第一段中critics的观点，后面坐着承认了Melville是浪漫主义，但又说这不是硬伤，只是表达自己的方式不同，完美对应E

最后一句有parallel，"and lowering the heat" which shows us slowing, instead of slows, 所以排除 B和E
"in which thin layers of extra paper are used "= thin layers of extra paper are used in a cigarette" 所以要用in不是for or that.

be likely to.. 不能省略be

but不是和同位语从句平行

(a) the lake holds..., more than ... combined. correct

problem in choice (e), which implies that lake baikal itself is somehow "more than all the North American Great Lakes combined". that doesn't make sense. →the fresh water才是比较对象
problem in choice (d), this is a direct comparison:(amount of water) IS MORE THAN (specific lakes) that's an illogical comparison; you can't compare a numerical amount of water (a numerical quantity) to a lake (a physical object).

被request的是increase，不是wages。。。。呃。。。

a选项：划线部分的were和之前的were重复了，一个句子只能有一个谓语动词，或者需要连词and把两个谓语动词隔开。

固定句型，just as A do B，so C do D

e选项，rates和exceeds主谓不一致，错误；而且rates和immigrants‘ 使用了双重所有格，错误。
