同近义词辨析

cannot but, cannot help, cannot help but

这组词都有“不得不，不禁”的意思，其区别是：

cannot but后跟不定式连用，是一种较正式的用法，主要用于美国英语。

cannot help与动名词连用，表示“不得不”是口语用法，词组中的help相当于avoid或prevent，是一种比较好的用法。

cannot help but 跟动词不定式连用，是cannot but与cannot help的混用，系书面用语，多用于美国英语。由于cannot help but含有双重否定，所以有人反对使用，认为不合习惯，但此表达法已经沿用下来。
