CHRISTMAS DAY 圣诞节 On Christmas Eve -- the night before Christmas Day -- children all over Britain put a stocking at the end of their beds before they go to sleep. Their parents usually tell them that Father Christmas will come during the night.
Father Christmas is very kind-hearted. He lands on top of each house and climbs down the chimney into the fireplace. He fills each of the stockings with Christmas presents.
圣诞老人心肠很好。他降落在每一家的房顶，顺着烟囱爬进壁炉。他给每一只长统袜装上圣诞礼物。
Of course, Father Christmas isn't real. In Jim and Kate's house, "Father Christmas" is really Mr. Green. Mr. Green doesn't climb down the chimney. He waits until the children are asleep. Then he quietly goes into their bedrooms, and fills their stockings with small presents. When they were very young, Mr. Green sometimes dressed up in a red coat. But he doesn't do that now. The children are no longer young, and they know who "Father Christmas" really is. But they still put their stockings at the end of their beds.
Mr. And Mrs. Green have stockings, too. They put small presents in each other's stockings. You're never too old to enjoy a Christmas stocking. They say. So they still have them.
Christmas Day always begins before breakfast. The children wake up very early, and can't wait to open the presents in their stockings. Then they wake up their parents, calling: "Merry Christmas!" They help their parents to open their stockings, too.
What does Christmas mean? Christmas Day is the birthday of Jesus Christ. When Christ was born nearly two thousand years ago, many people, rich and poor, gave him presents. So today, people still do the same thing to each other. Of course, everyone likes presents. But Mr. Green says: "It is better to give than to receive."
