题目内容

Today just as technology changed the face of industry, farms have undergone an “agricultural revolution”. On the farm of today, machines provide almost all the power.

One of the most important benefits will be the farm computer. A few forward-looking farmers are already using computers to help them run their farms more efficiently. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. Programs are being written for hog producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.

　　Another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand” that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make startling changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear sheep, drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is completed, the robots will automatically check to make sure that the milk is pure. The complete mobilization of the farm is far in the future, but engineers expect that some robots will be used before long.

Today just as technology changed the face of industry, farms have experienced an “agricultural revolution”. On the farm of today, machines provide almost all the power.

One of the most important benefits will be the farm puter. A few forward-looking farmers are already using puters to help them run their farms more efficiently. The puters help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock(家畜) to buy, when to sell their products, and how much profit they can expect. Many puter panies have been developing special puter programs just for farmers. Programs are being written for pig producers, grain farmers, potato farmers, and dairy farmers. In the future, farmers will be able to purchase puter programs made to their needs. Because of the growing importance of puters on the farm, students at agricultural colleges are required to take puter classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on puters even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on puter power.

Another technological advance which is still in the experimental stage is the robot, a real “mechanized hired hand” that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that puter-aided robots will make shocking changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to shear（修剪） sheep, drive tractors, and harvest fruit. Even plex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. In addition, when the milking is pleted, the robots will automatically check to make sure that the milk is pure. The plete change of the farm is far in the future, but engineers expect that some robots will be used before long.

Botany, the study of plants, occupies a special position in the history of human knowledge. For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest (含糊的) of insight. It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must extremely ancient. This is logical. Plants are the basis of the food pyramid for all living things, even for other plants. They have always been enormously important to the welfare of peoples, not only for food, but also for clothing, weapons, tools, eyes, medicines, shelter, and a great many other purposes. Tribes living today in the jungles of the Amazon recognized accurately hundreds of plants and know many properties of each. To them, botany, as such, has no name and is probably not even recognized as a special branch of knowledge at all.
Unfortunately, the more industrialized we become the farther away we move from direct contact with plants, and the less distinct our knowledge of botany grows. Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose, an apple, or an orchid. When our Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer productions the next season, the first great step in a new association of plants and humans was taken. Grains were discovered and from them flowed the wonder of agriculture; cultivated crops. From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild and the built up knowledge of tens of thousands of years of experience and close relationship with plants in the wild would begin fade away.
1. Which of the following statements about early humans is expressed in the passage?
A. They probably had extensive knowledge of plants.
B. They thought there was no need to cultivate crops.
C. They did not enjoy the study of botany.
D. They placed great importance on the ownership of property.
2. What does the comment “This is logical.” In the first paragraph mean?
A. There is no clear way to determine the extent of our ancestor’s knowledge of plants.
B. It is not surprising that early humans had a detailed knowledge of plants.
C. It is reasonable to assume that our ancestors behaved very much like people in pre-industrial societies.
D. Human knowledge of plants is well organized and very detailed.
3. According to the passage, why has general knowledge of botany begun to fade?
A. People no longer value plants as a useful resource.
B. Botany is not recognized as a special branch of science.
C. Research is unable to keep up with the increasing numbers of plants.
D. Direct contact with a variety of plants has decreased.
4. In the second paragraph, what is the author’s purpose in mentioning “ a rose, an apple, or an orchid”?
A. To make the passage more poetic.
B. To give an example of plant that are attractive.
C. To give botanical examples that all readers will recognize.
D. To explain the variety of botanical life.
5. According to the passage, what was the first great step toward the practice of agriculture?
A. The invention of agricultural tools and machinery.
B. The development of a system of names for plants.
C. The discovery of grasses that could be harvested and replanted.
D. The changing diets of early humans.
