    People in the United States honor their parents with two special days: Mother's Day, on the second Sunday

in May, and Father's Day, on the third Sunday in June. These days are set aside to show love and respect for

parents. They raise their children and educate them to be responsible citizens. They give love and care. These

two days make us think about the changing roles of mothers and fathers. More mothers now work outside the

home. More fathers must help with child care. 

    These two special days are celebrated in many different ways. On Mother's Day people wear carnations

which have two colors. A red one symbolizes (象征) a living mother. A white one shows that the mother is

dead. Many people attend religious services to honor parents. It is also a day when people whose parents are

dead visit the cemetery. On these two days families get together to have parties at home, as well as in

restaurants. These are days of fun and good feelings and memories.

    Another tradition is to give cards and gifts. Children make them in school. Many people make their own

presents. These are valued (珍爱) more than the ones bought in stores. It is not the value of the gift that is

important, but it is "the thought that counts". Greeting card stores, florists, candy makers, bakeries, telephone

companies, and other stores do a lot of business during these holidays.
