can't help doing和can't help but do的区别
如题,另外想问的是,but后面到底是跟动词不定式还是现在分词?为什么有的时候是动名词比如：I like nothing but swiming有时却是动词不定式比如：There was nothing to do but

can't help doing情不自禁地做某事
can't help but do=can only do sth 只能做某事.
but后面是接带to的不定式或是不to的不定式（即动词原形）.
I like nothing but swiming这里的swiming不能说它是动名词,应该是个名词.
but后面接带to的不定式或是不to的不定式（即动词原形）取决于它前面是否出现了实义动词do(做的意思,不是助动词)的具体形式.有,后面就用动词原形,没有,后面就用不定式.
There was nothing to do but wait
We have no choice but to wait.
PS：except也有这个用法.
