【正确答案】 D

【答案解析】这是一个can't help but“由不得……；不能不”句型的另一种表达方式，只不过把can't的否定意义表现在nobody一词上了，nobody can help but do sth. 相当于anybody can't help but do sth. 。如：Nobody can help but be moved by his stories. “没有人不为他的故事所感动。”注意下面两个句型可以表示类似的意思：can't help doing sth. (接动名词)，cannot but do sth. (接不带to的不定式)。这两个句型的意义完全相同，都是“不能不；禁不住”的意思。如：I can't (can-not) help laughing to hear such a story. I cannot but laugh to hear such a story. 注意区别三个句型在用法上的异同。
