On the old-time farm in America, there were chickens, cows, pigs and horses. But there were very few machines. Most of the work was done by the farm family. Sometimes more workmen were needed in busy seasons. Work done by horses took up 79 percent; by men, 15 percent; and machine work only took up 6 percent.

Today all that has changed. On many modern farms machines now will do 96 percent of the work, while man does 3 percent. As for horses, they do 1 percent of the whole work. The children go to school by bus every morning, the parents work on the farm or in the house and other people’s help is hardly needed. Their work has been replaced (取代) by a whole army of farm machines.

　　On the old-time farms in America there were chickens and turkeys (火鸡). There were also cows, pigs and other livestocks(家畜). But there were very few machines. Most of the work was done by the entire farm family with the help of a “hired man” . Sometimes extra labourers were needed in busy seasons. Horses provided 79 percent of the power used, labour 15 percent and machines only 6 percent.

　　Today all that has changed. On many modem farms machines now provide 96 percent of the power, human labour 3 percent, and horses 1 percent. Modern farms are enterprising (企业性的)business which keep only livestocks that can pay its way(支付费用). The children go to school by bus every morning, the parents work on the farm or in the house, and hired help is seldom needed. Their work has been replaced by a whole army of machines.

　　Farms in the machine age also use the new fertilizer, new feeds (饲料), new hybrid (杂交) seeds, and other helps developed by farm sciences. As a result the farmers are able to produce more food with less labour. This means fewer but larger farms, and fewer but more prosperous farmers.
