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.
A.Animals have driven humanitys success.
B.Tool-making and language are uniquely human habits.
C.Employing wolves is uniquely human habit.
D.People live with animals everywhere.

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 Their work has been replaced by a whole army of farm machines.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 nation’s forests have seen a sharp increase in violent incidents—equipment vandalized, people intimidated—over the past ten years. Shearer now carefully inspects every tree before cutting and has been using metal detectors to check every trunk being processed. Yet Ihor Mereszczak, of the Nez Perce Forest Service, says it has been hard to get the FBI’s attention, and investigations have got nowhere.
The ELF is only one thread in a web of underground radical environmentalists. Its aim is to inflict as much financial pain as possible on organizations or people who, by its lights, are exploiting the environment. The ELF, though made up of anonymous cells, nonetheless operates a website offering tips on how to cause fires with electric timers. Until recently, it also had a public spokesman.
Together with the Animal Liberation Front (ALF), which operates along the same lines, the ELF is estimated to be responsible for over $45m-worth of damage in North America over the past few years. In 1998, it caused fires that did $12m-worth of damage in Vail, Colorado, to make the point that the ski resort’s expansion was threatening places where lynxes live. Earlier this year, the ELF burned down the offices of a lumber company in Oregon. Since September 11th, the ALF and ELF have claimed responsibility for starting a fire at a primate research center in New Mexico, releasing mink from an Iowa fur farm, and firebombing a federal corral for wild horses in California.
Are they terrorists？ The two groups reject the label, claiming to take all precautions against harming “animals, whether humans or not”. But earlier this year Louis Freeh, the FBI’s boss, listed both organizations among the most active domestic terrorist groups. Scott McInnis, the Republican congressman whose district includes Vail, argues it is only a matter of time before somebody gets hurt, and he now expects the FBI to put in more resources.
The House subcommittee on forests, which Mr McInnis heads, will hold a hearing on eco-terrorism in February. But he has annoyed some mainstream green groups by asking them to denounce the ELF’s and ALF’s methods. Greenpeace, for instance, says that its disapproval is self-evident, and resents being asked to express it. Mr. McInnis still wants their answer by December 1st, but the war on eco-terrorism is off to a rocky start.
