第一段讲起源：
The religious duty,and pleasure,of thanksgiving to God was well established in England before any English speakers came to America,but it was the American colonials who made a feast of it.After the successful harvest of 1621 in the first year of pious Plymouth colony,Governor William Bradford called for a celebration.But rather than spending the day in prayer,the colonists set the pattern for future American Thanksgivings by inviting the neighbors to a big family dinner,with roast fowl as the main dish.
第二段讲庆祝方式：
In the United States,certain kinds of food are traditionally served at Thanksgiving meals.First and foremost,turkey is usually the featured item on any Thanksgiving feast table (so much so that Thanksgiving is sometimes referred to as "Turkey Day").Stuffing,mashed potatoes with gravy,sweet potatoes,cranberry sauce,corn,other fall vegetables,yams and pumpkin pie are commonly associated with Thanksgiving dinner.All of these primary dishes are actually native to the Americas and were introduced as a new food source to the Europeans when they arrived.
