Paragraph 6The contribution of geothermal energy to the world's energy future is difficult to estimate. Geothermal energy is in a sense not renewable, because in most cases the heat would be drawn out of a reservoir much more rapidly than it would be replaced by the very slow geological processes by which heat flows through solid rock into a heat reservoir. However in many places (for example. California, Hawaii, the Philippines. Japan, Mexico, the rift valleys of Africa) the resource is potentially so large that its future will depend on the economics of production. At present, we can make efficient use of only naturally occurring hot water or steam deposits. Although the potential is enormous, it is likely that in the near future geothermal energy can make important local contributions only where the resource is close to the user and the economics are favorable, as they are in California. New Zealand, and Iceland Geothermal energy probably will not make large-scale contributions to the world energy budget until well into the twenty-first century. if ever.

  11. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.

  O Heat flows through solid rock very slowly, so it takes a very long time for geological processes to produce a reservoir of geothermal energy

  O Geothermal energy is not renewable because heat flows very slowly through solid rock into or out of a heat reservoir

  O The heat quickly removed from a heat reservoir is replaced so slowly by geological processes that geothermal energy is not practically speaking, renewable

  O In most cases, heat travels into a heat reservoir so slowly that it is a much quicker process to remove the heat from a reservoir than to replace it

  题型:句子简化题

  解题思路: 所给句子中有一个明显的因果关系,讲的是地热能为不可再生能源的原因,选项C保留了原句主干,为正确选项。选项AD丢失了 renewable这一重要主干;选项B中的原因不全。

重点句子翻译:

  Geothermal energy is in a sense not renewable, because in most cases the heat would be drawn out of a reservoir much more rapidly than it would be replaced by the very slow geological processes by which heat flows through solid rock into a heat reservoir.

  地热能源是在一定意义上不能再生的,因为在大多数情况下,热量被抽出一个水库速度远远超过它被取代的速度,那将是非常缓慢的地质过程,其中热量通过坚硬的岩石流进一热储层。
