请问：how much 是做状语修饰 has 吗？为什么后面有个 of？

为什么不能写成：how much it has a chance of achieving such unprecedented goals.？

不可以那样改写，因为how much of a chance 作为一个整体充当动词 have 的宾语了

即结构为：have "how much of a chance of achieving such an unprecedented goals.（how much=百分之几=X%)

相当于：have +限定词+chance of doing sth 有一个“多大”做某事的可能性（这里限定词=how much of a chance)   (of doing sth是用来修饰chance可能性)

How much of +名词，表示“该名词所占比例即X%/机会/可能性/数量是多少？

how much of a chance =机会/可能性有多大=即X% 百分之几的可能性
