來吧，做題：

今天的題目：

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

昨天題目的解析：

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

  Concentration=merger=acquisition=consolidation 合并兼并

  Benefits 好處

  Costs 代價（害處）

  Scanty 稀少

  主干：Examples are scanty. 

  關于現在的兼并浪潮的好處和害處的例子還不多。

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

但是很難想象今天幾家石油公司的合并就會再次造成對于競爭的同樣的（same）威脅.

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

一個世紀以前在美國（人們）就擔心過這種威脅

when the Standard Oil trust was broken up.

那個時候標準石油托拉斯破產了。

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. 

   電信公司的合并，比如世界電信公司，并沒有為消費者造成來更高的價格或者造成技術進步的減緩。

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

  相反，通訊費用降低的很快。

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

   在汽車行業，合并也在增多，比如（witness）戴米爾 和克萊斯勒的合并，雷諾和尼桑的合并，但是看起來消費者并沒有受到傷害；

65. From Paragraph 4 we can infer that ________.

   段落推理題就是需要把四個選項分別和原文比對；

[A] the increasing concentration is certain to hurt consumers

   （合并的增加一定會傷害消費者。）

    這和最后一句是明顯相反的。所以排除！

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

     （ 世界電信是好處和壞處的好例子）

   第三句很明明確的表示：woirld com 表明了合并的好處；

[C] the costs of the globalization process are enormous

全球化過程的代價是巨大的。

文中沒有提到，排除！

[D] the Standard Oil trust might have threatened competition

標準石油托拉斯可能曾經對競爭造成過威脅；

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

造成當初人們擔心過得（same）的威脅；

那么意味著曾經有過對競爭的威脅，而且后面談到了那個時候標準石油托拉斯破產了；

所以這里是有依據的，只是如果直接讓大家選這個選項確實有難度，用排除法就會發現這個選項是無比的可愛，而且這個選項中還有might 再次讓我們確定這個選項是正確的！
