The idea of Mother’s Day is a very old idea. It was started by the ancient Egyptians (埃及人),who celebrated(庆祝) a day to honor (向……表示敬意) Isis, the mother of the pharaohs. The early Christians(基督教徒) celebrated a day to honor Mary, the mother of Jesus.
Later, English Christians celebrated to honor all mothers. This English holiday was called “Mothering Sunday”. When the English came to America, they did not have time for Mothering Sunday, so the holiday was not celebrated in America. In 1914,the U.S passed a law which designated(规定) the second Sunday in May as Mother’s Day to honor the mothers who had lost sons in war.
Today, Mother’s Day is celebrated in many other countries for all mothers. In Canada, Australia, New Zealand, Mother’s Day is celebrated on the same day as in the United States—the second Sunday in May. Children give their mothers cards, gifts, and flowers. Schools plan Mother’s Day’s special activities.
In China, the holiday is celebrated to show the respect(尊重) the Chinese have for the old people, and the love they have for their parents. Ten top mothers are chosen by the government. People all over the country try different ways to help mothers who are poor.
