    Children all over the world like to celebrate their birthdays. American children are of no difference.

They usually celebrate with a party. They invite their friends to their birthday parties. The party may

not be held on the right date of their birthday if it comes on a school day. It may be held on the weekend

instead.

    Today two kinds of parties are the most popular. One is held at home. Parents decorate the house

beautiful with balloons and coloured paper. They prepare a special birthday meal. The children play games.

The other kind is held away from home. Some are at a special restaurant. The children eat pizza and ice

cream. The waiters, who serve the food, also sing and tell jokes to the children. Other parties may be held

at a park, or at a movie theatre, or in some other places. Every birthday party has a cake with candles on it.

There is one candle for each year of a birthday boy's or girl's age. When the candles are lighted (点燃),

everyone sings the special birthday song: HAPPY BIRTHDAY TO YOU. 

    As Americans grow older, their birthday parties change. In fact, many people stop having them. They

say they would like to forget how old they are. Yet they do like to keep the happy birthday parties of their

childhood in mind.
