Everyone agrees that crime is partly a result of bad material conditions: poverty, lack of education, living within settled home, being parentless, sufferings from other kinds of misfortune, etc.
There are also other factors than material conditions which are responsible for the sharp increase of crime rate. In the first place, some state laws provide a death penalty but some not. Secondly, the Constitution (宪法) allows every citizen to carry weapons for his own protection. It is therefore possible and easy for anyone in the country to get a gun. Finally, there has been too much shown on TV and too much reported in newspaper of all kinds of crimes—the details of which are so accurately described that even children know how to duplicate what they have seen or read. All these have resulted in a high frequency of crimes committed both by professional criminals and by nonprofessional ones in murder, drug smuggling, robbery, etc.
The author intends to tell the readers that______.
A．the United States is a wealthy country although poverty and crime exist there
B．crime has become a serious problem in the United States, although it is said to be a prosperous one
C．despite the fact that crimes have been increasing rapidly in the United States, it is a country of prosperity
D．in spite of stories about poverty and crime in the United States, it is prospering at an increasing rate
In primitive times they did not travel for pleasure but to find new places where their herds could feed, or to escape from hostile neighbors, or to find more favorable climates. They traveled on foot. Their journeys were tong, tiring, and often dangerous. They protected themselves with simple weapons, such as wooden sticks or stone clubs, and by lighting fires at night and, above all, by keeping together.
Being intelligent and creative, they soon discovered easier ways of traveling. They rode on the backs of their domesticated animals; they hollowed Out tree trunks and,' by using bits of wood as paddles, were able to travel across water.
Later they traveled, not from necessity, but for the joy and excitement of seeing and experiencing new things, This is still the main reason why we travel today.
Traveling, of course, has now become a highly organized business. There are cars and splendid roads, express trains, huge ships and jet airliners, all of which provide us with comforts and security. This sounds wonderful. But there are difficulties. If you want to go abroad, you need a passport and a visa, ticket; luggage, and a hundred of other things. If you lose any of them, your journey may be ruined.
In primitive times men traveled ______.
A．for joy
B．from necessity
C．to broaden the mind
D．to escape from the wild animals
In 1870, horses and mules were the prime source of power on U. S. farms. One horse or mule was required to support four human beings—a ratio that remained almost constant for many decades. At that time, had a national commission been asked to forecast the horse and the population for 1970, its answer probably would have depended on whether its consultants were of an economic or technological turn of mind. Had they been "economists" , they would probably have projected the 1970 horse or mule population to be more than 50 million. Had they been "technologists", they would have recognized that the power of steam had already been harnessed to industry and to land and ocean transport. They would have recognized further that it would be the prime source of power on the farm. It would have been difficult for them to avoid the conclusion that the horse and mule population would decline rapidly.
According to the passage, what supplied most of the power on U. S. farms in 170?
A．Animals.
B．Humans.
C．Engines.
D．Water.
