Americans like to have different kinds of parties such as birthday parties, surprise parties, tea parties and house-warming parties. Pajama(睡衣)parties are one of the most popular kinds of parties in the US. At a pajama party, a group of friends spend the night at a person's house. It is a great way for children or teenagers to get together and have a good time.

To hold a pajama party, the host(东道主)will usually plan some fun activities such as watching movies and playing board games and video games. He or she should also prepare some delicious snacks and fun food like pizza. Guests at a pajama party should bring their own pajamas, toothbrushes, pilows and blankets(枕头和毯子).But if they forget something, they don't need to worry because the host will give them what they need.

If a pajama party is mainly for fun, a prom is no doubt a very important thing in most American schools. A prom is a formal(正式的)dance party that is held at a high school. The party is usually held near the end of the senior year, the last year of high school, so it is often called graduation(毕业)dance. Students are supposed to wear formal clothes at the prom. A Prom Queen and a Prom King may also be crowned(加冕)at many schools' proms.
