Slide 3: History of Halloween

Halloween can be traced back to ancient Celtic festivals, such as the Samhain Festival. This festival marked the end of summer and the beginning of winter, with people offering sacrifices to the gods in order to ensure a good harvest in the coming year. As Christianity spread through Europe, Halloween evolved into a day of prayer and fasting, with people dressing up in costumes to ward off evil spirits. Today, Halloween has become a family-friendly event, with people of all ages dressing up in costumes, carving pumpkins, and trick-or-treating.

Slide 4: Halloween Traditions

One of the most popular Halloween traditions is carving pumpkins. Pumpkins are carved into jack-o'-lanterns, which are then lit up and placed on doorsteps or windowsills. Another tradition is dressing up in costumes, with people dressing up as ghosts, witches, and other spooky characters. Trick-or-treating is also a common tradition, with children going from house to house to collect candy. Some people also participate in haunted house events or watch horror movies on Halloween night.

Slide 5: Halloween in English

In English, Halloween is often referred to as "Halloween Day" or "Halloween Eve". The word "Halloween" itself is derived from the Old English phrase "hallowe'en", which means "holiday of the dead". On Halloween Day, people often say "Happy Halloween" to each other, just like they would say "Happy Birthday" on someone's birthday. Children might also say "Trick or Treat" when they go trick-or-treating.

Another common phrase on Halloween is "Boo!", which is used to scare someone or to express excitement about the holiday. People might also dress up in "costumes" or "disguises" to look like their favorite Halloween characters. The most common costumes include ghosts, witches, and vampires.
