Today all that has changed. On many modern farms machines now supply 96 percent of the power, human labor 3 percent, and horses 1 percent. Modern farms are enterprising businesses which keep only the livestock that can pay its way. 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 Their work has been replaced by a whole army of farm machines.
Farmers in the machine age also use the new fertilizers, new sprays, new feeds, new hybrid 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.
In old days, most of the work on a farm was done by______.
A．all the farm family
B．livestock
C．farm machines
D．both A and B
The finest films of the silent era depended on two elements that we can seldom provide today a large and receptive audience and a well-orchestrated score. For the audience, the fusion of picture and live music added up to more than the sum of the respective parts.
The one word that sums up the attitude of the silent filmmakers is enthusiasm, conveyed most strongly before formulas took shape and when there was more room for experimentation. This enthusiastic uncertainty often resulted in such accidental discoveries as new camera or editing techniques. Some films experimented with players; the 1915 film Regeneration, for example, by using real gangsters and streetwalkers, provided startling local color. Other films, particularly those of Thomas Ince, provided tragic endings as often as films by other companies supplied happy ones.
Unfortunately, the vast majority of silent films survive today in inferior prints that no longer reflect the care that the original technicians put into them. The modern versions of silent films may appear jerky and flickery, but the vast picture palaces did not attract four to six thousand people a night by giving them eyestrain. A silent film depends on its visuals; as soon as you degrade those, you lose elements that go far beyond the image on the surface. The acting in silent was often very subtle and very restrained, despite legends to the contrary.
