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.
