It is well-known that the “prom”, a formal dance held at the end of high school or college, is an important date in every student’s lifE.

In May, high school seniors all around the U.S. scramble (争抢) to get ready for prom. Prom, short for promenade, is a formal dance held by a high school before graduation. It’s an important aspect of American school culture because it’s the last high-school dance seniors will ever attenD.

Prom involves countless traditions. First a guy must ask a girl to go to prom with him. Most guys choose to do special prom invitations in hopes of winning the girl’s heart with their creativity. Then they will rent a suit or tuxedo, and the girl will shop for an impressive dress. On the day of prom, girls will often get their hair, nails and makeup done professionally. That night couples will take pictures, and then they will often take a limousine (加长型礼车) to dinner and to the dancE. Several reports state that parents can spend up to $2,000 to give their kids the perfect prom experiencE.

The history of prom can date back to the last half of the 1800s. At that time, American universities and colleges organized dances each year for their graduating students. The purpose was not only to entertain the students but also to prepare them for the wider world by teaching them proper manners for men and women.

Later, high schools took over the prom tradition. In the 1950s, high schools began moving the dance from their gyms to beautiful hotels or country clubs to make the event even more special. Perhaps the most amazing prom took place in 1975, when Susan Ford, the daughter of the country’s president, received permission to hold her high school’s prom at the White HousE. So far, no other prom has managed to top that.

At the prom, boys usually dress in dinner jackets and bow ties, though many different types of formal clothes are worn. Traditionally, girls give boys matching boutonnieres (a small collection of flowers they pin to their jackets). Girls traditionally wear formal dresses, or dress to shock or be noticed, in shiny or brightly colored materials.

Common prom activities include dining, dancing, the crowning (加冠) of a prom king and queen, and just talking to friends. In some cases, high school students collect funds for their class prom through the four years of their high school.
