     In many countries, unusual names for children are becoming more popular, especially when more and

more stars give their children special names. In Britain, you can call a child almost anything you like except

dirty words.   

     Some parents choose names which come from popular culture. Because of the film the Lord of the Rings

(指环王), six boys were named Gandalf. Names about sport are very common, too. Since 1984, 36 children

have been called Arsenal after the football team.

     Other parents like to make up names, or combine (合并) two names to make a special one. A mother in

Britain invented the name Tiaamii for her daughter. She combined the names Thea and Amy (the two

grandmothers). 

     In China, there are some rules about names ―- you can't use foreign letters or symbols (符号) in a Chinese

name. For example, parents are not allowed to name their baby @. In New Zealand, a name beginning with a

number is not allowed. Other countries have stricter rules about calling children. For example, Japan,

Denmark, Spain, Germany and Argentina have a list of names. Parents must choose the names in the lists for

their children.

     In Britain, some old-fashioned (过时的) names have become popular again, such as Maisie or Ella for a girl,

and Alfie or Noah for a boy. But the most popular names are not the strange ones. The top names are very

traditional--Jack and Thomas for boys, or Grace and Jessica for girls.
