While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity.
再问OG 13 107题 107.While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity. (A) While it costs about the same to run nuclear plants as other types of power plants, it is the fixed costs that stem from building nuclear plants that makes it more expensive for them to generate electricity. (B) While the cost of running nuclear plants is about the same as for other types of power plants, the fixed costs that stem from building nuclear plants make the electricity they generate more expensive. (C) Even though it costs about the same to run nuclear plants as for other types of power plants, it is the fixed costs that stem from building nuclear plants that makes the electricity they generate more expensive. (D) It costs about the same to run nuclear plants as for other types of power plants, whereas the electricity they generate is more expensive, stemming from the fixed costs of building nuclear plants. (E) The cost of running nuclear plants is about the same as other types of power plants, but the electricity they generate is made more expensive because of the fixed costs stemming from building nuclear plants.
想问下D选项,OG 上的解释是The preposition for is redundant in comparing the two objects of run.
这里的it costs about the same to run nuclear plants as other types of power plants,是可以比较的呀???
D选项:It costs about the same to run nuclear plants as for other types of power plants
it是to run的形式主语,句子比较的是run nuclear plants costs $ 和other types of power plants cost $.
而B选项里的as for……及E选项里as后缺少for,是因为: 句子比较的是the cost of running nuclear plants和the cost of running other types of power plants=the cost for other types of power plants。
第一,A中as前后比较不对等。应该是 as to run other types; 而后乱用强调句;可以观察一下A中到底出现了多少个it,其强调句中又套着定语从句,them的指代问题,都是混乱而且支离破碎的。
第二,B中同样是while,但是这里就满足了while从句与主句要尽量严格地平行的要求,cost对cost; 其中 the cost of running is about the same as (the cost) for other types of 是省略的比较——建议参考庖丁解牛的介词短语比较的相关问题。
D选项:It costs about the same to run nuclear plants as for other types of power plants
it是to run的形式主语,句子比较的是run nuclear plants costs $ 和other types of power plants cost $.
而B选项里的as for……及E选项里as后缺少for,是因为: 句子比较的是the cost of running nuclear plants和the cost of running other types of power plants=the cost for other types of power plants。
这只是我自己的理解哈,如果不对,还请指正。

谢谢解释,现在才想到过来看,不好意思啊= = 那就是说,D选项去掉FOR之后变成 It costs about the same to run nuclear plants as other types of power plants 这个句子比较的对象是 run nuclear plants costs 和 other types of power plants,比较对象不对等?是这样吧..
我觉得把D是在比较run后面的宾语,就是nuclear plants和other types. 所以用for的话结构上就不平行了 但是我这里也有一个疑问,就是如果把D的for去掉就和A中while后面一样了,那么A当中的it costs about the same to run nuclear plants as other types of power plants,这样的表述方式是不是正确,会不会产生歧义呢?感觉比较对象是to run...和other types...但是发现OG上的解释并没有提及A有comparison的错误,所以很不确定。 是不是原意应该是it costs about the same to run nuclear plants as (to run)other types of power plans.但是把to run省略掉不会产生歧义么?
