Mother's Day is a holiday for mothers. It is celebrated (庆祝) in the United States, English, India and some other countries. In a short time, it becomes widely celebrated. Mother's Day falls on the second Sunday in May. On that day, many people send gifts (礼物) of love to their mothers. Those whose mothers are still living often wear a pink (粉红色) or red rose (玫瑰) or carnation (康乃馨花) , while those whose mothers are dead wear a white one. The idea of a day for mothers was first given by Miss Anna Jarvis of Philadelphia. As a result of her hard work, the celebration of the first American Mother's Day was held in Philadelphia on May 10,1908. Soon the holiday became popular all over the country and around the world.

In China, people do the same on the day for mothers. And , in some cities, people sometimes ask a song to be broadcast (广播) for his or her mother only. This might cost a little money for some of them, but, as it is said, "Love is invaluable."

On May 8,1999, just the day before the Mother's Day this year, a Chinese mother was killed in criminal bombing (罪恶轰炸).Her name is Shao Yunhuan , a heroic (英雄的) mother. All the Chinese will remember her for ever.
