A Few years ago, a university professor tried a little experiment. He sent Christmas cards to a sample of perfect strangers.

the receipt of such things that a term like “much obliged” has become a synonym for “thank you,” not only in the English language but in others as well.
The impressive aspect of the rule for reciprocation and the sense of obligation

SECTION A MULTIPLE CHOICE QUESTIONS
In this section there are three passages followed by ten multiple choice questions. For each multiple choice question, there are four suggested answers marked A, B, C and D. Choose the one that you think is the best answer and mark your answers on ANSWER SHEET TWO.
）
PASSAGE ONE
（1）The earliest settlers came to the North American continent to establish colonies that were free from the controls that existed in European societies. They wanted to escape the controls placed on their lives by kings and governments, priests and churches, noblemen and aristocrats. The historic decisions made by those first settlers have had a profound effect on the shaping of the American character. By limiting the power of the government and the churches and eliminating a formal aristocracy, they created a climate of freedom where the emphasis was on the individual. Individual freedom is probably the most basic of all the American values. By freedom, Americans mean the desire and the ability of all individuals to control their own destiny without outside interference from the government, a ruling noble class, the church, or any other organized authority.
(2) There is, however, a price to be paid for this individual freedom: self-reliance. It means that Americans believe they should stand on their own feet, achieving both financial and emotional independence from their parents as early as possible, usually by age 18 or 21.
(3) A second important reason why immigrants have traditionally been drawn to the United States is the belief that everyone has a equal chance to enter a race and succeed in the game. Because titles of nobility were forbidden in the Constitution, no formal class system developed in the .
(4) There is, however, a price to be paid for this equality of opportunity: competition. If much of life is seen as race, then a person must run the race in order to succeed; a person must compete with others. The pressures of competition in the life of an American begin in childhood and continue until retirement from work. In fact, any group of people who does not compete successfully does not fit into the mainstream of American life as well as those who do.
(5) A third reason why immigrants have traditionally come to the United States is to have a better life. Because of its abundant natural resources, the United States appeared to be a “land of plenty where millions could come to seek their fortunes. The phrase “going from rags to riches”became a slogan for the American dream. Many people did achieve material success. Material

New technologies and a rising interest in healthier and organic eating have had a huge impact on how farms do business. At the same time, a growing population has put more demands on farmers. They need to find ways to increase their production levels. The small family farms that used to produce most of the products have been largely replaced by factory farms. Small family farms that are still operating are struggling to keep up. Technology has made most aspects of farm life easier than it has ever been before. Bigger and more efficient equipment makes work such as plowing up fields and sowing the seeds easier. Such tasks used to take two or three times as long. These advances have allowed farmers to work faster and more efficiently than ever before. In addition to newer technology, factory farms produce more products for less money than traditional farming would require. Modern farm life, despite the introduction of new technologies, has not changed much from what has always been. Farmers still wake up early, and spend their days doing hard work. There are animals to feed, cows to be milked, and fields to be plowed. Farm still requires a lot of hard work and sacrifice. The main change in modern farm life is still in the way farms are run. It is common for even small farms to have several hired workers and even an animal manager. Family-run farms are becoming rarer. Factory farms, with other larger farm corporations, are becoming the norm. Although there are still many traditional family farms, they are quickly dying as modern practices change farm life forever. 1.Factory farms now produce most of the products A.True B. False C.
