how - much後面加什麼介詞

後面加介詞of，例如：

1、Reports conflicted on how much of the aid was reaching the famine victims.究竟有多少援助到了饑民手裏，相關報告彼此矛盾。

2、No test will reveal how much of the drug was taken.沒有哪項測試可以測出用藥量。

3、I think there is a limit to how much of this nonsense people are going to put up with.我想人們對這種胡鬧總有一個承受極限。

how much 是多少的意思，它可以作為特殊疑問詞放句首，後跟一般疑問句形式，how much 可以修飾不可數名詞，譬如how much meat多少肉
