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, stemmingfrom 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.


B选项中的for是什么意思？为什么不能删掉？谢谢！

我觉得barry说的很对，在此我来补充一下，如果有不对欢迎大家指正
——虽然前面zhima427的回复可以帮到大家明晰选项，但是并没有戳到本质

首先，五个选项可以分为两组
（1）ACD，开头结构都是it costs，其比较对象是to run different plants
（2）BE，开头是the costs of running，其比较对象是costs

我来把A、B选项的第一句话补充完整，大家就可以更好的看到区别了
A While it costs about thesame to run nuclear plants as other types of power plants,
——> to run nuclear plants costs about the same as (to run) other types of power plants

B While the cost of runningnuclear plants is about the same as for other types of power plants,
——> the cost of running n-plants is about the same as (the running costs) for other types ofpower plants


如果从语义来看，我们会发现，这道题想要比较的是cost本身。因为原句想要表达的是：
虽然运营成本基本一样，但是由于投建n-plant的固定成本高，因此n-plant发电总成本高。
因此答案只能集中在B和E中间选。
由于后一句已经省略了cost，那么介词结构for不能省略。

我们再回过头来看OG答案中提到for的问题的地方，应该就会觉得很清晰了：

D The preposition for is redundant in comparing the two objects of run.

E The preposition for is necessary in the comparison of the costs.

A说, it is the fi xed costs
that stem from building nuclear plants that makes it
more expensive for them to generate electricity，强调句就是去掉it is that 依然完整。。。这里面去掉之后，主语是costs，谓语是makes,主谓不一致。66 C D 多了一个for，，原文相比较的是run nuclear plants 比other type power plants 花费更高。。。不要加for。。。。。。。。。。。j                         E选项的 as other types of power plants少了一个for，不用for的话原句变成cost of running nuclear plants is about the same as other types of power plants，比较对象变成cost of runnng nuclear和 cost of other plants，核工厂的运营成本与其它工厂的成本（可能是收购成本）对比。当用for时，句子变成the cost for other plants，歧义消除
