     Are not you glad that mothers and fathers give names to their children? Names are the quickest and easiest

and the most friendly way to say who's who. Another nice thing about names is that they do not change as

people do. Yesterday Mary's hair was long. Today her hair is short. But her name is still Mary. On his birthday

Uncle Tom didn't have moustache (胡子). At Christmas time he did. But his name is still Tom. People are always

changing a little or a lot. But people's names are still the same. A name sometimes says something nice about

someone. Girls' names often come from words meaning "pretty", "happy", "loving"... Boys' names are often

borrowed from words which mean "strong", "brave".... Do you know how your name comes?
