阅读下面的短文,然后按要求写一篇150词左右的英语短文.

     Halloween is very popular in western countries. On October 31st, dozens of children dressed in

costumes(节日服装)knock on their neighbors' doors and yell "Trick or Treat" when the door opens.

Pirates and princesses, ghosts and popular heroes of the day all hold bags open to catch the candy or

other goodies that the neighbors drop in. As they give each child a treat the neighbors exclaim over the

costumes and try to guess who is under the masks.

     Today school dances and neighborhood parties called "block parties" are popular among the young

and the old. More and more adults celebrate Halloween. They dress up like historical or political figures

and go to masquerade parties(化妆舞会). In larger cities, costumed children and their parents gather

at shopping malls early in the evening. Stores and businesses give parties with games and treats for the

children. Teenagers enjoy costume dances at their schools and the more outrageous the costume the

better!

     Certain pranks(恶作剧)such as soaping car windows and tipping over garbage cans are expected.

But partying and pranks are not the only things that Halloweeners enjoy doing. Some collect money to

buy food and medicine for needy children around the world.
