考研英语（一）真题：阅读Text 2题源解析 1
The world is goingthrough the biggest wave of mergers and acquisitions ever witnessed. Theprocess sweeps from hyperactive America to Europe and reaches the emergingcountries with unsurpassed might. Many in these countries are looking at thisprocess and worrying: Wont the wave of business concentration turn into an uncontrollableanti-competitive force?
Theres no question that the big are getting bigger and morepowerful. Multinational corporations accounted for less than 20% ofinternational trade in 1982. Today the figure is more than 25% and growingrapidly. International affiliates account for a fast-growing segment ofproduction in economies that open up and welcome foreign investment. InArgentina, for instance, after the reforms of the early 1990s, multinationalswent from 43% to almost 70% of the industrial production of the 200 largestfirms. This phenomenon has created serious concerns over the role of smallereconomic firms, of national businessmen and over the ultimate stability of theworld economy.
I believe that the most important forces behind the massive MAwave are the same that underlie the globalization process: fallingtransportation and communication costs, lower trade and investment barriers andenlarged markets that require enlarged operations capable of meeting customersdemands. All these are beneficial, not detrimental, to consumers. Asproductivity grows, the worlds wealth increases.
Examples of benefits or costs of the current concentration wave arescanty. Yet it is hard to imagine that the merger of a few oil firms todaycould re-create the same threats to competition that were feared nearly acentury ago in the U.S., when the Standard Oil trust was broken up. The mergersof telecom companies, such as WorldCom, hardly seem to bring higher prices forconsumers or a reduction in the pace of technical progress. On the contrary,the price of communications is coming down fast. In cars, too, concentration isincreasingwitness Daimler and Chrysler, Renault and Nissanbut it doesnot appear that consumers are being hurt.
Yet the fact remains that the merger movement must be watched. Afew weeks ago, Alan Greenspan warned against the megamergers in the bankingindustry. Who is going to supervise, regulate and operate as lender of lastresort with the gigantic banks that are being created? Wont multinationalsshift production from one place to another when a nation gets too strict aboutinfringements to fair competition? And should one country take upon itself therole ofdefending competition on issues that affect many othernations, as in the U.S. vs. Microsoft case?
33. What is the typical trend of businesses today?
[A]To take in more foreign funds
[B]To invest more abroad
[C]To combine and become bigger
[D]To trade with more countries
34. According to the author, one of the driving forces behindMA wave is _________.
[A]the greater customer demands
[B]a surplus supply for the market
[C]a growing productivity
[D]the increase of the worlds wealth
35. From paragraph 4 we can infer that _________.
[A]the increasing concentration is certain to hurt consumers
[B]WorldCom serves as a good example of both benefits and costs
[C]the costs of the globalization process are enormous
[D]the Standard Oil trust might have threatened competition
36. Toward the new business wave, the writers attitude can be saidto be _________.
[A]optimistic
[B]objective
[C]pessimistic
[D]biased

One of the simplest and best known kinds of crystal is the ionic salt, of which a typical example is sodium chloride, or ordinary table salt. The fundamental components of an ionic salt are ions: atoms or molecules that have become electrically charged by gaining or losing one more electrons. In forming sodium chloride, for example, sodium atoms give up an electron (thereby becoming positively charged) and chlorine atoms gain an electron (thereby becoming negatively charged). The ions are attracted to one another by their opposite charges, and they stack together compactly, like tightly packed spheres.
Recently, scientists at Michigan State University created a new kind of crystal called an electride. In electrides, the anions (negative ions) are completely replaced by electrons, which are trapped in naturally formed cavities within a framework of regularly stacked cations (positive ions). Electrides are the first examples of ionic salts in which all these anionic sites are occupied solely by electrons.
Unlike other types of anions, anionic electrons do not behave as if they were simple charged spheres. In particular, because of their low mass and their tendency to interact with one another over great distances, they cannot be “pinned down” to any one location. Instead, they wander close to and among the atoms lining the cavity and interact with electrons in nearby cavities, perhaps changing places with them.
The properties of an electride depend largely on the distance between the cavities that hold trapped electrons. When the trapped electrons are far apart, they do not interact strongly, and so behave somewhat like an array of isolated negative charges. When they are closer together, they begin to display properties associated with large ensembles of identical particles. When they are still closer, the ensemble properties dominate and the electrons “delocalize”: they are no longer tightly bound within individual cavities but are more or less free to pass through the spaces within the framework of positive ions.
By synthesizing electrides from a variety of materials, one can vary the geometry of the anionic cavities and their relation to the surrounding cations. The resulting properties may make it possible for electrides to become a basis for economically useful new materials and devices. For instance, because the electrons in some electrides are very weakly bound, these crystals could be effective as photosensitive detectors, in which an impinging photon liberates an electron, resulting in a small electric current. The same weak binding could also make electrides useful in solar energy converters and as cathodes in batteries. One obstacle is the tendency of electrides to decompose through reaction with air and water. Researchers are seeking ways to increase their stability.

[A] readily lose electrons and become positively charged.
[B] move freely in and out of their cavities.
