[文法] "help"後面動詞+ing的原因？

[scju (QQ)]

大家好，請教一下。辭典裡看到help的例句

It helped a lot to know that someone understood how I felt.

這句可以理解。to know是不定詞片語修飾helped


It doesn't really help matters knowing that everyone is talking about us.

這句不懂了，knowing用ing的原因是什麼？原本是認為分詞構句，可是knowing改寫回去
的主詞會是it嗎？

我改寫是這樣：
It doesn't really help matters, although we know that everyone is
talking about us.

後面的主詞是we，和前面不一樣，應該不能化減為分詞構句？

還有其他例子，如：

 It helped being able to talk about it.

謝謝！

推 apei0816: 第一句是虛主詞概念：(Knowing that everyone is talkin
→ apei0816: g about us) -> S. doesn't really matter；第二句也是
→ apei0816: 哦：(Being able to talk about it)-> S. helped.
感謝a大，原來是主詞太長，用it虛主詞暫代的概念QQ

[Knowing that everyone is talking about us] doesn't really help matters.

[Being able to talk about it] helped.

名詞子句也有類似的用法呢。

推 serif: 以往看到虛主詞的句型，真主詞都是不定詞或that子句，
→ serif: 第一次看到用動名詞來寫的欸！
→ serif: 是因為不定詞會造成文意的混淆嗎？(真主詞or它幫忙做...)
推 dashihito: 跟樓上一樣問題+1！真主詞用Ving表示的多
→ dashihito: 半不是諺語嗎？
我不曉得耶，那些就是辭典上的例句....
