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 will usually plan some fun activities such as watching movies, playing board games or video games. He or she should also prepare some delicious sweets, fruits and fun food like pizza. Guests at a pajama party should bring their own pajamas, toothbrushes, pillows(枕头) and blankets(毛毯).
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 the graduation(毕业) dance. Students should wear formal clothes at the prom.
