代替 bananas 用 one 与 ones 的区别

Do you like bananas?
A: Yes,I do. But I don't want one.
B: Yes,I do. But I don't want any.

答案A和B有什么区别？

答案A为什么用 one 而不用 ones, bananas 是复数，如果用 one 代替前面出现过的词，不是要用 ones 吗？

one和ones作为名词替代词，替代前面出现过的可数名词以避免重复该名词。

替代不同于指代。指代词与先行词为共指，即先行词与指代词表示的是同一个人或事物，因此指代词的数必须与先行词的数保持一致。而替代词仅仅是避免了重复名词，先行词与替代词表示的是不同的人或事物，因此替代词的数不受先行词的数的限制。

例如：I don't want this small apple. Give me two big ones. (ones=apples, 但不包括前面所说的那个small apple.)

These apples look nice. Can I have a small one? (one 为名词替代词，=apple)

These apples look nice. Can I have one? (one为数词，=one apple. one不是名词替代词，后面省略了名词apple，不是替代。）

These apples look nice. Can I have any? (any为不定代词，=any apples)
