20．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．

分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了农场也经历了一场"农业革命"，在今天的农场里，机器几乎提供了所有的电力，可以帮助农民做很多事．
解答 62．A．细节理解题．从第二段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可知计算机不能帮助农民决定每年养的牲畜，故选A．
63．C．细节理解题．A答案错误在totally（完全地），太绝对．根据第三段Another technological advance which is still in the experimentalstage is the robot机器人只是在实验阶段，排除B选项，D答案可通过第二段第九至十行的信息排除；故选C．
64．C．从细节理解题．最后一段 Scientists are now developing robots that will be able to shearsheep，drive tractors，and harvest fruit．Even complex jobs will be done by robots…可以看出机器人可以干大多数农活；故选C．
65．B．主旨大意题．通读全文，可知本文就是围绕第一段第一句中agricultural revolution展开的，最因此佳标题是农业革命，故选B．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
