We use names every day. When we meet a new person, we usually ask, "What's your name?" It's important (重要的) to know a person's name. Names are different all over the world, so it is very difficult to know all names.
In the US, many people have a first name, a middle name and a last name. Parents choose the first names and middle names for their babies. There are names for boys and girls. For example, John, Peter, Tom and Mike are all names for boys. Elizabeth, Bonnie, Susan and Mary are all girls' names. The last name is the family name. Usually, it is the father's family name.
Everything has a name. Names are important.
