　　American farmers entered this century with some of the same problems that they came across during the last century. The most important of the problems continued to be overproduction (生产过剩). It is true that continuing improvements in farm machinery, better seeds, better fertilizers, and other good conditions have made farmers more and more successful in what they do.

　　In fact, American agriculture has become an "agribusiness", which includes a variety of farm businesses and organizations, from small, one-family companies to huge multinational companies (跨国公司) that own a great deal of land and that produce goods and materials used by farmers. The appearance of agribusiness in the late 20th century meant fewer but much larger farms. Sometimes owned by stockholders (股东) who didn't manage the farms, these large farms used more machinery and far fewer farm hands. In 1940, there were 6 million farms averaging (平均为) 67 hectares (公顷) each. In the late 1990s, there were only about 2.2 million farms averaging 190 hectares in size. During the same period, the number of farmers became smaller - from 12.5 million in 1930 to 1.2 million in the 1990s. In 1900, half of the labor force were farmers, but at the end of the last century only 2% worked on the farm. And nearly 60% of the remaining farmers at the beginning of this century worked only part-time on farms; they held other, non-farm jobs to add to their farm income. The high cost spent on land and equipment makes keeping the full-time farming going on very difficult for most people.

　　As these numbers show, the American "family farm" - rooted in the nation's history and in the story of the hard-working peasants - faces powerful economic challenges. Americans continue to imagine the neat barns (谷仓), fat farm animals, and beautiful fields of the traditional rural landscape, but it remains uncertain whether they will be willing to pay the price, either in higher food prices or in government aids to farmers who own the family farm.

　　1) What is the most important problem the American farmers meet with now?

A. The farm machinery needs to be improved.
