标题: 求助！OG12 CR97题~ [打印本页] 作者: learking 时间: 2010-7-31 18:05 标题: 求助！OG12 CR97题~ og12 97. Delta Products Inc. has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity. The question has been raised whether it can be concluded that for a given level of output Delta’s operation now causes less fossil fuel to be consumed than it did formerly. The answer, clearly, is yes, since the amount of fossil fuel used to generate the electricity needed to power the new technologies is less than the amount needed to power the older technologies, provided level of output is held constant.
In the argument given, the two boldfaced portions play which of the following roles?
(A) The first identifi es the content of the conclusion of the argument; the second provides support for that conclusion. (B) The first provides support for the conclusion of the argument; the second identifi es the content of that conclusion. (C) The first states the conclusion of the argument; the second calls that conclusion into question. (D) The first provides support for the conclusion of the argument; the second calls that conclusion into question. (E) Each provides support for the conclusion of the argument.
答案是选B，但还是想不通啊~~~
请问各路大侠，为什么第一句boldface是支持结论啊~~我觉得它不过是陈述了一个事实么~~~

第一个boldface有点牵强。。它其实是在介绍个类似背景的东西。。但是从第二个可以判出选B作者: phoenix89 时间: 2010-8-1 04:17 Delta Products Inc. has recently switched at least partly from older technologies using fossil fuels to new technologies powered by electricity.

楼主你说BF1是不是支持了结论的推出？作者: sugaryun 时间: 2010-8-1 04:34
第二个黑体就是结论。看后面说clearly yes就能判断。所以BF2 calls for the argument。 而第一个是事实加强。作者: 魏小妞要出国 时间: 2010-8-2 21:14
it can be concluded that这个地方就暗示了BF2是conclusion作者: crown48 时间: 2011-1-26 12:56 好解释！thx！！！作者: mia113 时间: 2011-7-24 22:19

同问D选项啊。。。作者: 猪王山 时间: 2012-10-22 08:24
选D的同学们，应该把 The question has been raised whether it can be concluded that for a given level of output Delta’s operation now causes less fossil fuel to be consumed than it did formerly.The answer, clearly, is yes。 当成一个整体看，the answer of the question......................is yes. 所以，上述整个部分是结论
