英语短语 "cannot help" 核心含义是“无法控制/忍不住做某事”,常用来表达“情绪或行为不受主观意志支配”的状态。它的用法需结合具体结构细分,以下是详细解析:
表示“因情感、习惯或外部刺激而无法抑制某种行为/想法”,相当于“can’t stop oneself from doing”(忍不住)。

易错点:不能说“cannot help to do sth.”(×),需用“doing”或“but do”。
错误:I can’t help to laugh. → 正确:I can’t help laughing. / I can’t help but laugh.
口语缩写:日常中更常用can’t help(cannot的缩写),更自然。
区分“忍不住”与“不能帮助”:
表“忍不住”:无宾语(或宾语是“doing”),如“I can’t help crying.”
表“不能帮助”:有宾语(sb.),如“I can’t help you.”
He can’t help himself—he always buys too many shoes.(他控制不了自己,总买太多鞋。)
