第二次错了！反问一下A中“they”和“their”有指代对象吗？！

无脑选B,虽然犹豫了一下！
It is used in making a "more than" type of comparison where you also want to refer to a previously stated verb / action (that's where the "so" comes in). In this case, the "so" refers to "reported high marital satisfaction."
Notice here that you are comparing two groups of women: those who take new jobs, and those who retire completely. When making a comparison, you have to make sure you explicitly mention both groups.
In fact, B and D change the original meaning of the sentence to make the second part of the comparison a hypothetical - but the original meaning is that the ones who take new jobs are being compared to those who don't.
for comparisons, they two things / groups / whatever compared should be parallel. "women who took" and "those who retired" are parallel.

选项c，in dong 正在做的事情，和人口没有关系

Because there is only one category mentioned (sense of smell) I think the word "difference" is appropriate.
more……as 错；more than/higher than/greater than 对

"even as" is a transition used to imply simultaneity, and is usually used with parallel tenses (i.e., same tense in both parts of the parallel structure). 主句从句的时态要保持一致;这里更需要用although表转折！
here's an example: even as his income has increased, joe has continued to feel less and less satisfied with his life.
比较C和E，C: HCa‘s fairy tales （have been among）……, still his plays，…，and travel books （remain） almost unknown outside.
E: Although HCA wrote fairy tales that (are among)……，his plays……and travel books （remain） ……
* first, the tenses should be parallel, since the descriptions are meant to be simultaneous.
* second, they should be the present tense, since the sentence is stating facts that are statistical truths.

我怀疑这答案有问题，不可能才500

B vs.D:用定语从句修饰同位语优于用伴随状语修饰，后者有明显的正在发生的倾向；
关于expect的固定搭配： expect to do…/sth. is expected to do…/…expect that sth. will do /it is expected that sth. will do /eg. Inflation rose more than we expected. /There is an expectation that……
WRONG：sth. is expected for it to do./ It is expected that sth.should do.

非限定性定语从句里which不是可以指代整个句子吗

原本M说：如果P和Q有交集，那么Q和R就没有交集；然而S推翻了M的说法，S说Q和R是有交集的，那也就是说P和Q没有交集咯，所以B对。。。。。。

个人认为E选项的条件句如果是 if it did so应该也没问题吧？
相比较而言。if it were to do， 强调主句潜在的结果特别糟糕或不可想象，if it did so 则没有这个强调作用

只是这里不能用不定式短语做主语

B-写错了吧？！文中的意图是仅仅次于大豆。

C large in quantities 有歧义

目前想到最快的是用梯形面积减去两三角形。求更快方法

B里面的capacity是产能并不是产量，产能增加了也不会代表产量增加。比如能生产500t，不等于会生产500t

定位：It may be that males can use scarce carotenoids either for immune defense and detoxification or for attracting females. 注意是or，所以不能同步。

和提示词离得远的细节题真的头疼

可以说，科学家到现在为止发现了17颗星星（可能之前发现了16颗，最近又发现了一颗，所以是到现在为止有17颗了），但不能说，科学家到现在为止发现了一件事，因为，发现一件事，要么就是发现了，要么就是没发现，没有“到现在为止发现”一说）。

17颗星星被环绕是一个客观事实，这个动作的时间不受discover的发生时间的影响。

看清楚题目定语从句引导词！
