解答
  准确地说应该是 I am afraid not to do = I am afraid (that) I can't do
  【解析】be afraid 后面可以跟一下几种结构:
  1、介词 of 短语,如:
    He is afraid of his own shadow.(他连自己的影子都害怕.)
  2、不定式短语(肯定式是 be afraid to do,否定式是be afraid not to do).如:
I'm afraid to be late.我可能要迟到了.
I'm afraid not to be invited.我恐怕不会受到邀请.
  3、that 引导的从句(that 可以省略)
I'm afraid (that) I'm wrong.恐怕我错了
I am afraid (that) you don't see my point.恐怕你还没有明白我的意思.
  只要行为者既是 be afraid 的主语又是不定式的逻辑主语或从句的主语,不定式和从句是可以互相转换的.如:
  不定式转换为从句——
肯定句:I'm afraid to be late 可以转换为 I'mafraid I’ll be late.我可能要迟到了.
否定句:I'm afraid not to be invited.可以转换为 I'm afraid I will/can not be invited.
  从句转换为不定式——
肯定句:I'm afraid I’m wrong 可以转换为 I'm afraid to be wrong.
否定句:I am afraid (that) I don't see yourpoint 可以转换为I am afraid not to see your point.
  至于从句中是用 do not、will not 还是can not/could not 需要视语境的情况而定.
