Aren't 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.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 always 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?
