只想说一做句：所谓道德都是为自己不喜欢的人准备的态度而已。

每个人都有自己价值评判，宽容一点，世界会美好一点。

世界再热闹，我们都要守住自己的坚持！

来吧，做题：

今天的题目：

That the plates are moving is now beyond dispute. Africa and South America, for example, are moving away from each other as new material is injected into the sea floor between them. The complementary coastlines and certain geological features that seem to span the ocean are reminders of where the two continents were once joined. The relative motion of the plates carrying these continents has been constructed in detail, but the motion of one plate with respect to another cannot readily be translated into motion with respect to the earth’s interior. 

68.That Africa and South America were once joined can be deduced from the fact that ________.

[A] the two continents are still moving in opposite directions

[B] they have been found to share certain geological features

[C] the African plate has been stable for 30 million years

[D] over 100 hot spots are scattered all around the globe

昨天题目的解析：

1. Examples of benefits or costs of the current concentration wave are scanty. 

  Concentration=merger=acquisition=consolidation 合并兼并

  Benefits 好处

  Costs 代价（害处）

  Scanty 稀少

  主干：Examples are scanty. 

  关于现在的兼并浪潮的好处和害处的例子还不多。

2.Yet it is hard to imagine that the merger of a few oil firms today could recreate the same threats to competition/

但是很难想象今天几家石油公司的合并就会再次造成对于竞争的同样的（same）威胁.

that were feared nearly a century a in the U.S.

一个世纪以前在美国（人们）就担心过这种威胁

when the Standard Oil trust was broken up.

那个时候标准石油托拉斯破产了。

3. The mergers of telecom companies, such as WorldCom, hardly seem to bring higher prices for consumers or a reduction in the pace of technical progress. 

   电信公司的合并，比如世界电信公司，并没有为消费者造成来更高的价格或者造成技术进步的减缓。

4. On the contrary, the price of communications is coming down fast. 

  相反，通讯费用降低的很快。

5. In cars, too, concentration is increasing -- witness Daimler and Chrysler, Renault and Nissan -- but it does not appear that consumers are being hurt.

   在汽车行业，合并也在增多，比如（witness）戴米尔 和克莱斯勒的合并，雷诺和尼桑的合并，但是看起来消费者并没有受到伤害；

65. From Paragraph 4 we can infer that ________.

   段落推理题就是需要把四个选项分别和原文比对；

[A] the increasing concentration is certain to hurt consumers

   （合并的增加一定会伤害消费者。）

    这和最后一句是明显相反的。所以排除！

[B] WorldCom serves as a od example of both benefits and costs

     （ 世界电信是好处和坏处的好例子）

   第三句很明明确的表示：woirld com 表明了合并的好处；

[C] the costs of the globalization process are enormous

全球化过程的代价是巨大的。

文中没有提到，排除！

[D] the Standard Oil trust might have threatened competition

标准石油托拉斯可能曾经对竞争造成过威胁；

it is hard to imagine that the merger of a few oil firms today could recreate the same threats to competition

造成当初人们担心过得（same）的威胁；

那么意味着曾经有过对竞争的威胁，而且后面谈到了那个时候标准石油托拉斯破产了；

所以这里是有依据的，只是如果直接让大家选这个选项确实有难度，用排除法就会发现这个选项是无比的可爱，而且这个选项中还有might 再次让我们确定这个选项是正确的！
