     In the United States, sixteen, eighteen and twenty-one are important ages in a person's life. There are no

special celebrations for these birthdays, but each is a time when a person can do new things. That shows

how she is no longer a child and has made the transition to adulthood.

     In the United States,after turning sixteen a person can work, get a driver's license, and leave home.

Sometimes the laws don't seem to make sense (表明): at eighteen people in the United States can have a vote

and join the army. But people are prohibited (禁止) from going into many nightclubs, buying drinks like beer

or wine until they are twenty-one.

     In many Latin American countries, a young woman's fifteenth birthday is important. At this age, she is no

longer considered to be a girl, but rather a woman. To mark this special day,families with fifteen-year-old

daughters have a celebration. The day begins with the young woman and her family going to church. Later,

there is a party and many guests are invited.

     In Japan, boys and girls are considered to be adults at the age of twenty. At this age, they are allowed by

law to vote, drink wine, and smoke. The second Monday in January is a national holiday called "Coming of

Age Day". On this day, twenty-year-olds celebrate by first going to a shrine (神庙) with their families. Later,

they listen to speeches given by city and school leaders. After that, many get together with family late into the

night.

     In some countries, birthday celebrations continue throughout adulthood. Some people celebrate their

fortieth and fiftieth birthdays, or the year when they retire, with a big party.
