Question

help Do sth与help doing sth有什么区别？

Answer 1

help doing sth和help to do的区别是释义不同、用法不同等。

1、释义不同：help doing与can't连用，意为忍不住／情不自禁去做某事；help to do意为帮助、援助。

2、用法不同：help (to) do sth实际上有时候to是省略掉的，用作help do sth。

help + doing是与can't一起用的，用作can't help doing sth。容易与can't help doing混淆的是can't help to do，译为不能帮助做某事。

I can't help doing sth.我情不自禁做。

Need sb to do sth I need her to help me with the cooking.我需要她来帮我做饭。

May I ask a favour of you (ie ask you to do sth for me)?请您帮个忙行吗？

Take it into one's head to do sth.突然决定做某事，心血来潮。

很高兴为你解答！
help do sth.实际上是help后加省略to的不定式，有时也可以不省略，即help to do sth. 表示“帮忙做某事”，例句：
Can you help (to) clean the room?
help doing sth. 一般用于否定句，表示“忍不住或情不自禁做某事”
He couldn't help missing his parents.
