Who give us life，raise us and are our constant support and well­wishers？Our mothers.That’s why millions of people across the world take Mother’s Day as an opportunity to express thanks and send best wishes to their moms.

However，the celebration of Mother’s Day is not the recent thing that many believe it to be.It was the ancient Greeks who started the tradition by celebrating their annual spring festival in honor of Rhea，the mother of many gods and goddesses.

Later，in the 1600s，Mothering Sunday came to be celebrated in England.On the fourth Sunday of Lent (大斋期)，children brought flowers and special fruitcakes to show their respect for their mothers.It may be the root of the modern Mother’s Day.

Thanks to the great efforts of Julia Ward Howe and Anna Jarvis，Mother’s Day became an official festival in the US.It is celebrated on the second Sunday in May.Later，many countries began to celebrate this day as Mother’s Day.

Today，Mother’s Day is an international festival honoring mothers.It is celebrated all over the world in different ways.In Western countries，the most common way is to treat mothers with breakfast in bed.Kids often allow their mothers to sleep till late in the morning while they prepare her favorite breakfast with their fathers.Some also make hand­made gifts or buy beautiful carnations (康乃馨)．It is the day when you acknowledge your mothers contribution in your life and pay a tribute (礼品) to her，often with flowers and gifts.It complements Father’s Day，the celebration honoring fathers.

Today，Mother’s Day is a day celebrated on various days in many places around the world.
