　　Thanksgiving which falls on the fourth Thursday of November, is one of the biggest American holidays. Thisholiday started in the early 1600's after settlers arrived in America. These people who came from Europedidn't know how to survive in the wild new country. Luckily, they met some friendly American Indians, whoshowed them how to hunt turkeys and grow corn. In the fall, after the harvest, the settlers had a greatfeast. They invited the Indians to thank them for their help.
