(A) it is so debilitating that it has become an economic
(B) it is of such debilitation, it has become an economical
(C) so debilitating is it as to become an economic
(D) such is its debilitation, it becomes an economical
(E) there is so much debilitation that it has become an economical
   答案 A，原句没有倒装，就不优选C？；即使A也显得罗嗦？（讨论！）

1.so as to 一般不倒装（没有严格验证过，只是没看到倒装的）
2. so as to 用在句中，无法体现动词的时态
本句中原句时态为has become，表示已经完成的动作，而在so as to 中无法体现这一动作的状态

讨论。。。
