Passage Two
How can a single postage stamp be worth $ 16,800？
Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one in expensive' postage stamp has made the stamp worth a million and a half times its original value.
The mistake was made more than a hundred years ago in the British colony of Mauritius, a small is land in the Indian Ocean. In 1847 an order for stamps was sent to a London printer, and Mauritius was to become the fourth country in the world to issue stamps.
Before the order was filled and delivered, a ball (舞会) was planned at Mauritius' Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the de sign for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the sever al hundred stamps that he printed.
Today there are only twenty-six of these misprinted stamps left--fourteen "One Penny Orange-Reds" and twelve "Two Penny Blues". Because of the Two Penny Blue's rareness (罕见) and age, collectors have paid as much as $ 16,800 for it.

A. there are few others like it
B. there are no errors on the stamps
C. a mistake is made in the ,printing

This spurt of suburban expansion, however, does not alter the basic fact that the United States has become one of the most urban nations on the face of the earth. Census (人口调查) Bureau figures show that the rural population has been shrinking steadily since 1830. When the United States became a nation it had no large cities at all; today some fifty cities have populations of more than 258 ,000. Mammoth complexes of cities are developing in the area of the East Coast and the east north-central states, on the Pacific and Gulf coasts, and near the shores of the Great Lakes. Some sociologists now regard the entire 600-mile stretch between Boston and Washington, D. C.—an area holding a fifth of the country' s population—as one vast city or, as they call it, megalopolis.
A traditional American belief is that ______.
A．few people live on farms
B．the nation consists mainly of small towns and wide open spaces
C．the population is the greatest in the world
D．the United States is a nation of big cities
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
