　　ne

　　One / ones is used to avoid repeating a countable noun, but there are some times when you should not use it, especially in formal speech or writing. one/ones用以避免重复可数名词，但有时候，尤其在正式谈话或书面语中，不应使用：

　　1 After a possessive ( my , your , Mary’s , etc.), some , any , both or a number, unless it is used with an adjective. 在表示所有关系的词（如my、your、Mary's 等）、some、any、both或数字之后不用one/ones，除非与形容词连用：

　　‘Did you get any postcards?’ ‘Yes, I bought four nice ones.’
