他因削弱

dash 必须成对出现，排除cde；平行结构--> "Archaeologists have excavated a hull that is X and that represents Y." -->选A

为啥不是so persistent were her lobbying….，就是因为看到这个倒装里没有状语才pass的

limited to suppliers of items that are directly related to end products. 文章第一句话指的就是direct purchase

定位句With "indirect" purchases (such as computers, advertising, and legal services), which are not directly related to production, corporations often favor "supplier partnerships" (arrangements in which the purchaser forgoes the right to pursue alternative suppliers), which can inappropriately shelter suppliers from rigorous competitive scrutiny that might afford the purchaser economic leverage.
supplier partnerships会给供货商提供一种庇护，从而使得他们不受消费者货比三家而给自己带来的（负面）影响。competitive scrutiny可以理解为消费者进行货比三家的活动，这种行为能够给消费者带来经济上的杠杆效应（economic levergae），言下之意就是对消费者有利，对供货商则不利。___cd

文中有提到的There are two independent variables—availability of alternatives and ease of changing suppliers—that companies should use to evaluate the feasibility of subjecting suppliers of indirect purchases to competitive scrutiny. 用这两个变量去衡量不同的状况就是strategy，而讨论这个strategy在应用在不同环境就是其application

C. 【错误】《伊莱克特拉》只在中世纪手稿L中有，其它中世纪手稿里没有，在L里没评论，等于说在中世纪的所有手稿中都没有评论，所以E正确。但是在除开中世纪的手稿，古代其它时间的手稿中有没有关于《伊莱克特拉》的评论，我们是无法从文章给定信息中得知的。
medieval意思是中世纪

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.
