普通高中课程标准实验教科书《英语》电子课本 Book 3 Unit 1 Festivals around the world B3U1P1-3 FESTIV ALS AND CELEBRATIONS Ancient Festivals Festivals and celebrations of all kinds are held everywhere. The most ancient festivals would celebrate the end of the cold weather, planting in spring and harvest in autumn. Other celebrations were held when hunters could catch animals. They would starve if food was difficult to find, so they celebrated when they had food. They lit fires and made music because they thought these festivals would bring a year of plenty. Festivals of the Dead Some festivals are held to honour the dead, or satisfy and please the ancestors, who could return either to help or to do harm. In Japan the festival is called Obon, when people should go to clean the graves and light incense in memory of their ancestors. They light lamps and play music because they think that this will lead the ancestors back to earth. In Mexico they have the Day of the Dead in early November. On this important feast day, people might eat food in shape of skulls, and cakes with “bones” on them. They offer food, flowers and gifts to the dead. The festival of Halloween had its origin as an event in memory of the dead. It is now a children’s festival, when they can go to their neighbours’ homes and ask for sweets. They dress up and try to frighten people. If they are not given anything, the children might play a trick. Festivals to Honour People Festivals can be held as an honour to famous people or to the gods. One of these is the Dragon Boat Festival in China, which honours the famous ancient poet, Qu Yuan. Another is Columbus Day in the USA, in memory of the arrival of Christopher Columbus in America. In India there is a national festival on October 2 to honour Mahatma Gandhi, the leader who helped gain India’s independence from Britain. Harvest Festivals Harvest and Thanksgiving festivals can be very happy events. People are grateful because their food is gathered for the winter ,and because a season of agricultural work is over. In European countries it is the custom to decorate churches and town halls with flowers and fruit, and people get together to have meals. Some people might win awards for their animals, flowers, fruits and vegetables, like the biggest watermelon or the most handsome rooster. In China and Japan there are mid-autumn festivals, when people admire the moon and give gift of mooncakes. Spring Festivals The most energetic and important festivals are the ones that look forward to the end of winter and to the coming of spring. At the Spring Festival in China, people eat dumplings, fish and meat, and may give children lucky money in the red paper. There are dragon dances and carnivals, and families celebrate the lunar New Year together. In some Western countries there are very exciting carnivals, which take place forty days before Easter, usually in February. They might include parades, dancing in the streets day and night, loud music and colourful clothing of all kinds. Easter is an important religious and social festival in Christian countries. It celebrates the return of Jesus for Christians and it also celebrates the coming of spring. In Japan, the Cherry Blossom Festival happens a little later. The country is covered with cherry tree flowers so that it looks as though it might be covered with pink snow. People love to get together to eat, drink and have fun with each others. Festivals let us enjoy life, be proud of our customs and forget our daily life for a little while.
