Answer 1

这是个固定搭配，意思是恐怕不能怎么样、、、如果放在前面意思是我不怕、、、意思就不一样了。

Answer 2

"Not" can be used with certain verbs such as hope, seem, believe, expect, think, guess and also with be afraid, being a more polite than just saying no.
Ex. `Have you got much money?' `I'm afraid not';
Ex. `Is he going to fail his exam?' `I hope not'.

Answer 3

固定搭配 我恐怕不是这样
