大全515，too。。to

515.Most energy analysts now agree that the costs of building and maintaining nuclear reactors are too high for nuclear power to likely prove cheaper than coal or oil in the long run.

(A) too high for nuclear power to likely

(B) high enough for nuclear power to be unlikely to

(C) high enough that it is unlikely nuclear power will

(D) so high that nuclear power is unlikely to（D）

(E) so high as to be unlikely that nuclear power will

我答案是选对了，但我不明白A里的too－－to为什么错，大家对too－－to的用法有好的建议吗？请多多指教呀

too...to likely prove

awkward

A项，太高了以至于不能说明便宜。。说得通吧？？为啥？？A不对

A 的逻辑有问题.

costs of building and maintaining nuclear reactors are too high for nuclear power to likely prove cheaper than coal or oil in the long run

=> costs are too high to prove cheaper than coal or oil =>costs to prove cheaper than coal or oil 错.

cost high是原因. nuclear power to prove (nuclear power ) cheaper than coal or oil.

谢谢楼上的解释，通了，PROVE的发出者应该是NUCLEAR POWER，A TOO B TO C， C的动词发出者是A

如下举例

老贴新问，请指点。

A是 A too B for C to D,有解释：

用 "too…to…"句型表达时，我们可以将for + Noun/Pronoun结构用在to + infinitive之前。eg. (1) The question was so difficult that we could not answer it.

(从句中的Subject为 "we" ，而主句的Subject为 "The question"。) = The question was too difficult for us to answer.

如同正确答案一样，这里的nuclear power的确是prove的发出者啊
