someone
1.someone作“某人”解。例如：Get a light, someone? 不作“某一个”解。说“某一个”该用some one。例如：Some one of his friends will help him. 和Choose some one of these pictures for your room. 把some one用作“某人”解也可以，但不很普通。
2.someone不可用作“若干人”或“某某若干人”解，下面两句意思不同：
- Someone says so. （某人［只有一个人］这样说。）
- Some say so. （若干人［有些人］这样说。）
3.参见somebody 2
4.用了someone，不可用one，one's等词指它，如不可说Someone has left one's handkerchief on the table，该把one's改作his或her。
