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
不认得assimilated和commonplace
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

这个削弱是同因异果的削弱! 要注意manufacturing是上升了的
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"
这题art glass前面应该再加一个逗号的吧?
