cant help doing,cant help but do,have no choice but to do,couldn't do nothing but do这些都怎么理解
不要死记,我想知道为什么是这样

cant help doing,情不自禁做某事
cant help but do 不得不做某事
,have no choice but to do,除了做某事别无选择
couldn't do nothing but do只有做否是
再问：那为什么是这样的，有的有to，有的没to
再答：一般情况下就是but to do，but前有do时 to省略 cant help but do 是固定搭配
再问：为什么前面有do的时候to省略？里面语法是什么》？？？？？麻烦了
再答：这本来就是语法
