Task 1 Directions: This part is to test your reading ability. There are 5 tasks for you to fulfill. You should read the reading materials carefully and do the tasks as you are instructed. The traditional American Thanksgiving Day celebration goes back to 1621. In that year a special party was prepared in Plymouth, Massachusetts. The colonists (殖民者) who settled there had left England because they felt that they were not given religious freedom. They came to the new land and faced difficulties in coming across the ocean. The ship which carried them was called the Mayflower. The North Atlantic was difficult to travel. There were bad storms. They were helped in learning to live in the new land by the Indians who inhabited the region. The Puritans(清教徒), as they were called, had much to be thankful for. Their religious practices were no longer a source of criticism by the government. They learned to adapt their farming habits to the climate and soil. When they selected the fourth Thursday of November for the Thanksgiving celebration, they invited their neighbors, the Indians, to join them in dinner and a prayer (祈祷) of gratitude for the new life. They recalled the group of 102 men, women, and children who left England. They remembered their dead who did not live to see the shores of Massachusetts. They reflected their 65 days' Journey which tested their strength.
