Today just as technology changed the face of industry, farmers have undergone an agricultural revolution. On the farm of today, machines provide 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(猪) 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. 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 complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the special barn(畜棚), 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.

(答案→)A 解析：文章讲述了农业革命，未来的农业将依靠计算机和机器人。【小题1】大意题。文章的主题段就是第一段，主题句也就是第一句Today just as technology changed the face of industry, farmers have undergone an agricultural revolution.农业面临着革命。【小题2】推理题。根据第一段倒数第2句modern farms depend on machine power可知现在的农民主要依靠的机器。【小题3】细节题。根据第2段5,6行Even complex jobs will be done by robots. For example, in order to milk their cows。【小题4】主旨大意题。文章的第一句就提及了本文的中心思想农业的革命。

对的，就是这个意思
