     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 offer a chance to think about the changing roles of mothers and fathers.

More mothers now work outside the home. More fathers must help with child-care.

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

carnations. A. red one stands for a living mother. A. white one shows that the mother is dead. Many

people attend religious services(宗教仪式)to honor parents. It is also a day when people whose parents

are dead visit their graves. On these days, families get together at home and in restaur ants. They often

have outdoor BBQs for Father's Day. 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 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,

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