Part I 教材原文&翻译
I just got a new laptop. It is very helpful. When Ms. Liu asked us to write a report about Easter, I decided to do all of my research on the Internet. I entered some key words into a search engine to find information on this topic. Here is what I found.
What is Easter
Easter is an important festival in Western culture. It's one of the biggest holidays in many countries.
When is Easter
Easter does not fall on the same day each year. The date depends on the moon, but it is always in March or April.
How do people celebrate Easter
People celebrate Easter with their family and friends. They eat delicious food together. In this way, it is like the Chinese Spring Festival. On Easter Day, many children have egg hunts and eat chocolate rabbits. Rabbits and eggs are symbols of new life. Children believe that the Easter Bunny comes and hides chocolate eggs for them to find.
