including不对 好像前面小说包括后面两本似的 而且 the others being是为数不多的being正确用法

平行，前面的是书那后面的也必须是书，排除acd
且前面是Jean Toomer's Cane，(b) is not as parallel as (e), either. since the original says "jean toomer's cane", the others should also have the form "X's Y", not "Y by X".

RON：
word choice is a sticky thing. for instance, it's actually better to say "birds have a four-chambered heart" than to say "birds have four-chambered hearts", because the former makes it clear that each bird has exactly 1 heart. both, however, are acceptable.
in a similar vein, the construction of (d) and (e) makes it more clear that each book has exactly 1 author.

C选项是两者共同点

我们需要知道对比的两者为“两个时间发生的情况”。本句的意思是：“历史上没有哪次哈雷彗星回归造成了跟1910-1911回归的这样的世界性范围的轰动。”

比较主谓 共用一个主语 比较状语

Were it not for意思是：如果不是的话，和instead意思重复了。所以A,B错误。同时需要注意的是前半句用到了代词it和its，所以后半句需要明确指出代词指代对象，通过代词its core这里就可以判断出its指代的是star。最后，would do 和would have done的区别在于，would do是指将来，would have done是指过去应该做什么，完全不同。

在语法上，代词they和it（包括他们的宾格）会“完全指代”一个名词，即，先行词的所有定语部分均被包括在这个代词的指代对象中。在(A)(B)(E)中，their/them/the doctors都属于特指前文中出现的Nineteenth-century doctors；在(C)(D)中，doctors指“另外一些医生”。

注意 E 只说了压力 压根没说长寿 不能臆想！ C同理 完全没说长寿 而且 即便与原文再契合 哪怕是只差一两个单词 不符合CQ就是错的

关于“being”有一点不是很赞同老师的解释。
转换为共同所有权应该是修饰”building“的吧，那就不存在老师说的反复出现啥的。这个解释是不是就不通了。更赞同下面的这个解释

Also, we don't want to say "undergoing being converted." Like most uses of "being," this is awkward and unnecessary. In this case, we have a simple noun--"conversion"--so there's no reason not to use that.

请教老师，E选项的Efforts have not been significant in a reduction of the gaps，是不是可以理解为 Efforts 不够 significant，曲解了愿意，愿意是努力没有带来足够的结果？

A 句子不完整
B rise不能defy
C 并列表独立不相关，此处不合适
D correct
E and to do不对，is continuing不对

"growing them naturally" is illogical.
in this construction, "them" (= fish) is the OBJECT of "growing". this implies that someone else must be growing the fish -- which doesn't make sense if we're talking about natural growth.

notice that the correct answer contains "they grow naturally", a more accurate description of what actually happens -- the fish just grow, by themselves.

D

ok 我看错了 以为主语是impeachment

有点像数学题，根据原文提供的条件：1 眼疾患者对中等强度的亮光敏感 2 他们对暗淡的光线敏感度一般（可接受） 3 对红色中等强度的亮光接受度也还可以 =====问哪个结论可以由这些信息推出----只有D可以依靠原文信息推出

定位句：If a clone loses many stems simultaneously, the resulting hormonal imbalance triggers a huge increase in new, rapidly growing shoots that can outnumber the ones destroyed.

However, recent studies on harbor seals, a phocid species.../The maternal strategy evolved by harbor seals may have to do with their small size and the large proportion of their fat stores depleted in lactation.

定位句：Zoologists had assumed that females of all phocid species, by contrast, use a fasting strategy in which mother phocids, having accumulated large energy stores before they arrive at breeding sites, fast throughout the entire lactation period, which lasts from 4 to 50 days depending on the species.

还是没有理解题意
