例如：李萍的书 翻译为：Li Ping’s books 具体用法为：
Grammar Focus
“名词+'s”所有格
1) 单数名词后加“ 's ”（以-s结尾的人名后加“ ' ”或“ 's ”）。

2) 以-s结尾的复数名词只加“ ' ”，不以-s结尾的复数名词通常加“ 's ”。

“名词+'s”所有格主要用于有生命的名词的所有关系。

of 所有格
1) of 所有格多用于表示无生命事物的名词的所有关系。
a map of China 一幅中国地图
2) of 所有格也可用于表示人和其他有生命的名词的所有关系。
the name of her cat 她的猫的名字
the girl’s new dress = the new dress of the girl 这个女孩的新连衣裙
3) ’s所有格和of 所有格有时可以互相转换。
