母亲节是什么时候？when is Mothers Day

母亲节是五月的第二个星期日。今年母亲节那天，我为母亲买了一件毛衣和一束鲜花作为礼物，感谢母亲为我付出的辛苦。母亲收到礼物后，非常高兴。

Mother＇s Day comes on the second Sunday in May each year. On that day this year, I bought a sweater and some flowers for my mother to thank her for her hard work for me. Receiving my gift, my mother was very happy.
