语法问题！！adj enough for sb to do

baibaibaibai

manhattan 中的语法问题，，语法idom里提到可以用enough for sb to do这种形式，，但是后面练习题第十题很疑惑：

The chemical processes were complex enough to require additional analysis, (complex
enough to do) RIGHT

这个句子对

The chemical processes were complex enough for them to require additional analysis,
(complex enough for them to do) WRONG

为什么这个句子不对了呢，？？
求人解答哈，，谢谢大神们！！！跪拜·~~

them指代不清 所以第二个错误。 一般来说复数指代可以用ones 或者those 但是不能用they 除非是人
正常来说 enough to的形式是不赞同的，偏向于口语化，多数情况下属于错误选项。

The chemical processes在句子中是主语而非宾语，所以"for them" 多余且没有必要

manhattan中前面几页有另外一个句子“The book was short enough for me to read in one night”－－right， 此句不同的是强调book 是for me的
