Mother’s Day is a holiday for mothers. And on this day, mothers don’t work. It is on the second Sunday in May. It is celebrated in the United States, England, Sweden, India, Mexico and some other countries. Little by little, it becomes widely celebrated. On the day, many people send presents of love to their mothers. Those whose mothers are still living often wear a pink or red rose or carnation(康乃馨). 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. The celebration of the first American Mother’s Day was held in Philadelphia on May 10, 1908. Soon the holiday became popular around the country and the world.
