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.
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。作者: WayneCH2012 时间: 2012-10-11 20:30
同样不懂，那个for不是不对称吗？the cost of running unclear plants 怎么和介词短语for other types of power plants对称呢？如果像3楼说的那应该是that of types of power plants.这不是很好的对称吗？怎么就用for呢？作者: aduoyi 时间: 2012-10-12 06:32

(C) Even though it costs about the same to run nuclear plants as for other types of power plants, it is the fixed coststhat stem from building nuclear plants that makes the electricitthey 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 costsof 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 buildingnuclear plants
