这题做了两遍都错了.
E选项错在，检测了变色龙种类中的一个共性，没有提到它们的共性，文章只是研究变色龙是到达岛屿之前还是之后进化出三个种类。用examine也不对，提出的两个explanation都是正确的，只是确定这个变色龙的进化属于哪一种

By the mid-1850's the inclusion of women in the rituals of party politics had become commonplace and the ideology that justified such inclusion had been assimilated by the Democrats.
had become commonplace=imitated；
C：文章只说了assimilated（同化、吸收）该ideology，并没有说该ideology是被他们create的

原文说的是低估women's political allegiance ，E选项说的是忽略woman's rights movement。
不认得allegiance ,意思是忠诚.

没找到定位句,最后一句The culprits for service-sector productivity stagnation are the forces—such as corporate takeovers and unnecessary governmental regulation—that distract managers from the task of making optimal use of available resources.
culprits罪魁祸首

读懂题干！削弱budget-deficit对discrepancy的解释！
discrepancy是指为什么manufacturing的productivity增长了，而service sector的productivity下降。budget的explanation是说因为interest rate的上升导致的，第三段第一句说道利率越低，投资越好，productivity就高，而现在service sector的productivity低就是因为利率高造成的。E选项正确在于，它说道利率贵manufacturing和service sector的影响是一样的，也就是不会出现一个growth了另一个却decline，就weaken了budget这个解释

E. 解决关于技术使用的分歧意见（未涉及解决争端，非正确选项）
C. 对意外的调查结果作出解释（通篇解释 paradox: IT 没有带来预料中的经济优势，即使段末说明了一些好处，也是和其他补充一起获得，不是单纯依靠 IT, 正确）
unexpected findings = "productivity paradox"

定位:seamstresses, meanwhile, were impatient with the remaining restrictions on their right to clothe women.
seamstresses女裁缝
没有看懂这篇文章

定位句:yet no countries-with the possible exceptions of Malaysia and Thailand-have even approached their success.大部分国家都失败了(除了泰国和马来西亚).理解错了,以为泰国失败了.
A 承认一个广泛传播的说法的不真实性,没有说不真实,只是有例外
B对,说明有例外

” Aspens' need for fire may seem illogical since aspens are particularly vulnerable to fires; whereas the bark of most trees consists of dead cells, the aspen's bark is a living, functioning tissue that-along with the rest of the tree-succumbs quickly to fire”，前面提及Aspen需要火看起来不合理因为易受到伤害， whereas后转折，大不多数树树皮是死的，而Aspen树皮是活的，抵挡不住火
succumb：v. 屈服; 屈从; 抵挡不住(攻击、疾病、诱惑等);bark树皮

定位: If a clone loses many stems simultaneously, the resulting hormonal imbalance triggers a huge increase in new, rapidly growing shoots tha.
t can outnumber the ones destroyed.
如果有火（或者别的disturbance）这一篇地区的树都会挂，由此带来的imbalance会引发大量新的快速发育的枝芽，并且新芽数量比因为火烧而挂了的还多
其实这个disturbance是刺激杨树细胞生长的，通过产生不平衡的荷尔蒙使杨树产生新细胞。A这个选项乍一眼看上去是一个负面的表达，大家肯定是想找disturbance带给杨树的好处。但是仔细读文章就能发现其实不平衡才会刺激新细胞产生，和文章说的意思一样。

For example, G10 garnets, a type of garnet typically found in diamond-rich pipes（D）, are lower in calcium and higher in chrome(C) than garnets from barren pipes. Geochemists John Gurney showed that garnets with this composition were formed only in the diamond-stability field(E); more commonly found versions(B） came from elsewhere in the mantle.
这里的同意替换比较难.

A明显说的是后面的氧化问题。和这个G10没关系.

In the last sentence of the passage, the author refers to "recent archaeological discoveries" most probably in order to?
White发现Martin的thesis取决于人类到来的时间与大型动物的灭绝的时间相同，而Krech虽然意识到了时间有争议，但他并没有提出异议。但最近的考古研究证明人类到来的时间其实早了11000年。因此说明人类到来与灭绝没有直接关系。因此反对Martin和Krech，也就是支持了White。

Which of the following, if true, would most weaken Krech's objections to Martin's theory?
C的问题是，选项想用“同因反果”来削弱K的观点，即，P era有climatic change, 有灭绝，其他era也有climatic change, 但是却没有灭绝，所以climatic change不是导致灭绝的原因。但是选项中并没有提到其他era没有灭绝这件事，这是我们自己脑补的事实，即选项中并没有提供“果”，所以错
有关B的argument是：“Nor were extinctions confined to large animals: small animals, plants, and insects disappeared, presumably not all through human consumption.”意思是说，不光大动物灭绝了，小动物和植物昆虫也灭绝了，不可能人类还consume小动物啥的吧（所以不可能是human consumption导致大动物灭绝）。所以B说人类确实use了这些小动物，就是一个很直接的削弱。

错误定位到White observes that Martin's thesis depends on coinciding dates for the arrival of humans and the decline of large animal species, and Krech, though aware that the dates are controversial, does not challenge them.这里M并没有提出对日期的争论!
正确定位Krech also contradicts Martin's exclusion of climatic change as an explanation by asserting that widespread climatic change did indeed occur at the end of the Pleistocene.
这句话没理解,意思是K反驳了M把气候变化排除掉.

D. 是这些norms受到了mercantilist notions的支持，而不是norms帮助贯彻了mercantilist notions，故错误

原文：Clearly price promotions are generally run at a loss, otherwise there would be more of them.
所以 没有经常举办这个活动的原因是因为run at a loss即亏本，没有利润
问题问价格促销对于利润的影响（即没有利润）的证据是什么，就是因为没有经常举办这个活动呀，没有经常举办这个活动就是它亏本的证据

A.他们证实了研究人员对地幔内部对流可以垂直抬升或降低地球表面的理论的怀疑。
D.他们已经让以前持怀疑态度的研究人员相信，非洲南部地下地幔深处的岩层可能创造了superwell.
没注意问题里面的细节词语!!不是confirm doubt.
做CR也经常错这个

定位点在However, recent technological advances have allowed geophysicists to make three-dimensional "snapshots" of the mantle by measuring vibrations, or seismic waves, set in motion by earthquakes originating in the planet's outer shell and recording the time it takes for them to travel from an earthquake's epicenter to a particular recording station at the surface. Because geophysicists know that seismic waves become sluggish in hot, low-density rock, and speed up in colder, denser regions, they can now infer the temperatures and den- sities in a given segment of the interior.我看成后面一句话了.

have greatly downsized复数，表明主语是companies而不是B company。

tech = plant varieties + chemical
文章后半段分为：
1. 教育程度 ⬆️ => plant ⬆️ chemical ⬇️
2. 市场连接 ⬆️ => both ⬆️
3. 可用未开垦土地 ⬆️ => both ⬇️
4. kinship ⬆️ => plant ⬆️ chemical ⬇️
在不用想太复杂的情况下，看完题干就会想到是两个都⬇️的情况，就是D了
