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。
