2013年GMAT考试阅读模拟试题及答案10

　　The general density dependence model can be applied to explain the founding of specialist firms (those attempting to serve a narrow target market). According to this model, specialist foundings hinge on the interplay between legitimation and competitive forces, both of which are functions of the density (total number) of firms in a particular specialist population. Legitimation occurs as a new type of firm moves from being viewed as unfamiliar to being viewed as a natural way to organize. At low density levels, each founding increases legitimation, reducing barriers to entry and easing subsequent foundings. Competition occurs because the resources that firms seek--customers, suppliers, and employees--are limited, but as long as density is low relative to plentiful resources, the addition of another firm has a negligible impact on the intensity of competition. At high density levels, however, competitive effects outweigh legitimation effects, discouraging foundings. The more numerous the competitors, the fiercer the competition will be and the smaller will be the incentive for new firms to enter the field.

　　While several studies have found a significant correspondence between the density dependence model and actual patterns of foundings, other studies have found patterns not consistent with the model. A possible explanation for this inconsistency is that legitimation and competitive forces transcend national boundaries, while studies typically restrict their analysis to the national level. Thus a national-level analysis can understate the true legitimation and competitive forces as well as the number of foundings in an industry that is internationally integrated. Many industries are or are becoming international, and since media and information easily cross national borders, so should legitimation and its effects on overseas foundings. For example, if a type of firm becomes established in the United States, that information transcends borders, reduces uncertainties, and helps foundings of that type of firm in other countries. Even within national contexts, studies have found more support for the density dependence model when they employ broader geographic units of analysis--for example, finding that the model\'s operation is seen more clearly at the state and national levels than at city levels.

　　文章概况:第一段说有一个density model能解释公司的一些事情.后面一直给细节,low density的时候这个公司能怎么样,high density的时候这个公司能怎么样.第二段文章上来就说虽然这种model能解释一些东西,但是还是和公司的一些东西不一致.后面解释了为什么不一致,并在结尾给出了一个例子!

　　4 细节题,问的是这个model和founding不一致的原因.根据文章脉络我们很容易知道此题考察第二段内容,文章第二段首局就开始说这个model和founding不一致,但是我问的是原因,原因在哪?显然是第二句,我们把第二句读一下: “egitimation and competitive forces跨越了国家边界,而研究只能限于本国.”我们来看看选项

　　A 过度预计影响,没提过,杀

　　B 没有关注竞争起的作用,没提过,杀

　　C 使不同的公司有所区分,没提过,杀

　　D 没有考虑到是国际的,和原文国家边界有点关系,留着

　　E 忽略了某些公司,没提过,杀.
