51.Thanksgiving p.348

    Thanksgiving which falls on the fourth Thursday of November, is one of the biggest American holidays. This holiday started in the early 1600's after settlers arrived in America. These people who came from Europe didn't know how to survive in the wild new country. Luckily, they met some friendly American Indians, who showed them how to hunt turkeys and grow corn. In the fall, after the harvest, the settlers had a great feast¹. They invited the Indians to thank them for their help. Today the tradition continues. On Thanksgiving Day, Americans invite their friends over for a turkey dinner and give thanks for what they have.
