单选题Thanksgiving Day is the most truly American of the national holidays in the United States and is most closely connected with the earliest history of the country. In 1620, the settlers, or Pilgrims, sailed to America on the Mayflower, seeking a place where they could have freedom of worship. After a two-month voyage, in icy November, they landed at what is now Plymouth, Massachusetts. During their first winter, over half of the settlers died of starvation or epidemics (流行病). Those who survived began sowing in the first spring. All summer long they waited for the harvests with great anxiety, knowing that their lives and the future of the colony depended on the coming harvest. Finally the field produced a yield rich beyond expectations. And therefore it was decided that a day of thanksgiving to the Lord be fixed. Years later, President of the Unites States decided the fourth Thursday of November as Thanksgiving Day every year. The celebration of Thanksgiving Day has been observed on that date until today. The pattern of the Thanksgiving celebration has never changed through the years. The big family dinner is planned months ahead. On the dinner table, people will find apples, oranges, chestnuts and grapes. There will be pudding, mince (肉馅) pie, other varieties of food and cranberry (越橘) juice and lemon juice. The best and most attractive among them are roast turkey and pumpkin pie. They have been the most traditional and favorite food on Thanksgiving Day throughout the years.

单选题Americans have contributed to many art forms, and jazz, a type of music, is one of the art forms that were started in the United States. Black Americans, who sang and played the music of their homeland, created jazz. Jazz is a mixture of music of Africa, the work songs the slaves sang, and religious music. Improvisation (即兴) is an important part of jazz. This is why a jazz song might sound a little different each time it is played. Jazz bands formed in the late 1800s. They played in bars and clubs in many towns and cities of the South, especially New Orleans. New Orleans is an international seaport, and people from all over the world come to New Orleans to hear jazz. Jazz became more and more popular. By the 1920s, jazz was popular all over the United States. By the 1940s, you could hear jazz not only in clubs and bars, but in concert halls as well. Today, people from all over the world play jazz. Jazz musicians from the United States, Asia, Africa, South America, and Europe meet and share their music at festivals on every continent. In this way jazz continues to grow and change.

单选题A great change in agriculture in the 19th century included two things: the invention of labor-saying machines and the development of scientific agriculture. Labor-saving machines naturally appeared first where more labor was needed. "In Europe," said Thomas Jefferson, "the object is to make good use of their land, labor being abundant (充裕的); here it is to make good use of our labor, land being abundant." It was in America, therefore, that the great advances in the 19th century agricultural machines first came. At the opening of the century, with the exception of a crude plow, farmers could have carried practically all of the existing agricultural tools on their backs; by 1860, most of the machines in use today had been designed in an early form. One of the most important early inventions was the iron plow. As early as 1790 Charles Newbold of New Jersey had been working on the idea of a cast-iron plow and spent his entire fortune in introducing his invention. The farmers, however, would have none of it, declaring that the iron poisoned the soil and made the weeds grow, however, many people devoted their attention to the plow; until in 1869 James Oliver of South Bend, Indiana, turned out the first chilled-steel plow.
