听力原文: Abraham Lincoln's father, Thomas Lincoln, was born in Virginia in 1778. In 1781 the family moved to Kentucky. He became a skilled carpenter, and he was never short of food. At one time he owned two farms. He always owned one or more horses. On June 12, 1806, Thomas Lincoln married Nancy. She came from a very poor Virginia family. She had no education and signed her name with an X after their marriage. Thomas Lincoln earned his living as a carpenter and handyman. In 1807 a daughter, Sarah, was born. On February 12, 1809, in a log cabin that Thomas Lincoln had built, Abraham was born. When Abraham Lincoln was two, the family moved to another farm. Life was lonely and hard. There was little time for play. Most of the day was spent hunting, farming, hashing, and doing farm duties. In 1816 the Lincolns decided to move to Indiana, where the land was surveyed and sold by the government. In the winter of 1816 the Lincolns took their small property, settled in Indiana. Because it was winter, Thomas Lincoln immediately built a simple, three-sided shelter flat served as home until he could build a log cabin. A fire at the open end of the shelter kept the family warm. At this time southern Indiana was a heavily forested wilderness. Lincoln described it as a 'wild region, with many bears end other wild animals in the woods.' Nancy died on October 5, 1818 because of some serious disease. The next year, Thomas Lincoln went to Kentucky, and married Sarah Bush Johnston, a widow with three children. Abe Lincoln was very much fond of his kind stepmother. (35)
