请解释为什么

can't help to do sth是指不能帮助别人作某事；
eg：i can't help you to finish your work.

而can't help doing sth是指情不自禁作某事
eg：i can not help laughing.

A

B

A 因为help这里是帮助的意思，而can't help+动名词结构是禁不住……

A根据意思来说：他不能帮助修理房间，因为他正忙于做蛋糕。 can't help to do sth是指不能帮助别人作某事； can't help doing sth是指情不自禁作某事.

楼主，是这样的，can't help doing表示情不自禁做某事

这里，我们要把can't 和help分开来看，句子翻译成;他不能帮忙打扫房间，因为她在忙着做蛋糕，所以help to do sth，所以用to clean
