Thanksgiving Day is celebrated by Americans and more and more people join this festival. This day reminds people of the grateful heart. The coming of Thanksgiving Day comes back to the 17th century. At that time, about 100 people were driven out of UK and they were sent to the wasted land by the ship called May Flower. The local people taught them how to survive and then the first American were formed. In order to show gratitude to the Indians, American people named a day to celebrate it. It can also teach children to be grateful all the time for the things and the happiness they own.
