lets help后加to do ,do,还是doing

help doing 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。
3、例句：
（1）I can't lift this box — will you help me please? 译文：我举不动这个箱子,请你帮我一下好吗?
（2）I couldn't help crying.译文：我忍不住哭了。
（3）He can't help to do housework,for he is busy. 他由于忙不能帮助干家务。

help的其它用法：
1、help sb.with sth.意为“帮助某人做某事”或“在……方面帮助某人”。有时在上下文意思清楚时，help sb.(to) do sth.意思相近。
例句：You can help me carry the things./ You can help me with the things.译文：你可以帮我拿这些东西。
2、help oneself (to) +名词,意为“请随便吃……”。这是招待客人的常用语,oneself有人称和数的变化。
例句：Help yourself to some chicken. 请随便吃些鸡肉。

help (to) do sth实际上有时候to是省略掉的。
help do sth

还有can't help doing sth.(忍不住/情不自禁去做某事）

help + doing 是与can't一起用的
