《麦克米伦高阶英汉双解词典》some 词条指出：some 也可以“后接单数可数名词”，例句是：She married some guy she met on the boat. 她和在船上遇到的一个人结婚了。
请问，some 在那种情况下可以表示“一个”，后面接单数可数名词？
当 some 所表达的意义为 a certain “某一；某个”时，可接可数名词的单数形式。牛津高阶英汉双解词典》有如下讲解：
person, place or thing that is unknown or unspecified 未知的或未确指的人﹑ 地址或事物:
Some man at the door is asking to see you. 门口有人要见你。
She won a competition in some newspaper or other. 她参加某报纸举办的比赛获胜。
▲再提供两个词典例句：
He is working at some place in the north. 他在北方某地工作。《现代汉英综合大词典》
Some careless man has taken my umbrella.某个粗枝大叶的人拿走了我的雨伞。《21世纪英汉汉英双向词典》
