American has always been a land of beginnings. After Europeans 'discovered' America in the fifteenth century, the mysterious New World became for many people a genuine hope of a new life, an escape from poverty and persecution, a chance to start again. We can say that, as nation, America begins with that hope. When, however, does American literature begin？ American literature begins with American experiences. Long before the first colonists arrived, before Christopher Columbus, before the Northmen who 'found' America about the year 1,000, Native Americans lived here. Each tribe's literature was tightly woven into the fabric of daily life and reflected the unmistakably American experience of lining with the land. Another kind of experience, one filled with fear and excitement, found its expression in the reports that Columbus and other explorers sent home in Spain, France and England. In addition, the journals of the people who lived and died in the New England wilderness tell unforgettable tales of hard and sometimes heartbreaking experiences of those early years. Experience, then, is the key to early American literature. The New World provided a great variety of experiences, and these experiences demanded a wide variety of expressions by an even wider variety of early American writers. These writers included John Smith, who spent only two-and-a-half years on the American continent. They included Jonathan Edwards and William Byrd, who thought of themselves as British subjects, never suspecting a revolution that would create a United States of America with a literature of its own. American Indians, explorers, Puritan ministers, frontier wives, plantation owner -- they are all the creators of the first American literature. What does 'that hope' in the first paragraph refer to？ A．The hope that America would be discovered. B．The hope to start a new life. C．The hope to see the mysteries of the New World. D．The hope to find poverty here.

The American victory in the Revolutionary War united 13 of the English-speaking settlements into the largest and most powerful political unit in the territory , even though those first 13 states hugging the eastern coast seem small compared with the country' s eventual size. As a result of the Revolution ,approximately 71 , 500 people out of a population of some 2. 5 million fled the new United States. Some were Loyalists - political or economic refugees whose loyalties to Great Britain remained strong; others were blacks seeking refuge from slavery. Immigration and the commercial slave trade after the war quickly restored the population to its former level. The Revolution also opened up the area west of the Appalachian Mountains to settlement , as fur traders and farmers were no longer confined by British settlement restrictions. Pioneering citizens , immigrants , and slaves moved west , displacing Native Americans who had hoped to preserve their cultures undisturbed by the expanding United States. The 17th and 18th centuries saw a growing importation of Africans into North America. After 1808 U. S. law forbade the importation of slaves from abroad , although some smuggling of slaves continued. Few people from Africa chose to come to the United States voluntarily (the free African population was small) because they were considered second-class citizens , and confined largely to the northern states. Large numbers of Europeans migrated to the United States in the early national period , drawn by the promise of freedom , cheap land in the West , and jobs in the first factories of the emerging industrial age. The influx of Europeans , the end of the slave trade , and the ongoing wars removing Native Americans meant that some of the racial diversity of the population was diminishing. By the early decades of the 19th century , a greater proportion of Americans were of western European and Protestant heritage than at the time of the Revolution. Over the course of the 19th century , the United States gradually absorbed the French colonists in the upper Midwest and in New Orleans , Louisiana; the Spanish and Russian colonists in the South , West ,and Northwest; and the territories of the Hawaiian people and other indigenous groups. Sometimes these territories were added by diplomacy , sometimes by brute force. European visitors were surprised at the diversity in nationalities and in religious and secular beliefs in early America , as well as the number of intermarriages between people of differing European heritages. There were also cross-racial births , sometimes voluntary and sometimes by force , but rarely within legal marriages. The population continued to grow through migration as well , driven in part by English , Irish , and German settlers who came in large numbers around 1848 to escape political repression and food shortages in Europe. 31.

听力原文： The traditional American Thanksgiving Day celebration goes back to 1621. In that year a special feast was prepared in Plymouth, Massachusetts. The colonists who had settled there had left England because they felt denied of 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 assisted in learning to live in the new land by the Indians who in habited the region. The Puritans, 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 adjust their fanning habits to the climate and soil. When they selected the fourth Thursday of November for their Thanksgiving celebration, they invited their neighbors, the Indians, to join them in dinner and a prayer 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 on the 65 days' journey which tested their strength. What is the best title for this passage？ A．First Settlers in Plymouth. B．Puritans and Indians. C．Mayflower. D．American Thanksgiving Day.
