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 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了農(nóng)場也經(jīng)歷了一場"農(nóng)業(yè)革命"，在今天的農(nóng)場里，機(jī)器幾乎提供了所有的電力，可以幫助農(nóng)民做很多事．
解答 62．A．細(xì)節(jié)理解題．從第二段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可知計(jì)算機(jī)不能幫助農(nóng)民決定每年養(yǎng)的牲畜，故選A．
63．C．細(xì)節(jié)理解題．A答案錯(cuò)誤在totally（完全地），太絕對．根據(jù)第三段Another technological advance which is still in the experimentalstage is the robot機(jī)器人只是在實(shí)驗(yàn)階段，排除B選項(xiàng)，D答案可通過第二段第九至十行的信息排除；故選C．
64．C．從細(xì)節(jié)理解題．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…可以看出機(jī)器人可以干大多數(shù)農(nóng)活；故選C．
65．B．主旨大意題．通讀全文，可知本文就是圍繞第一段第一句中agricultural revolution展開的，最因此佳標(biāo)題是農(nóng)業(yè)革命，故選B．
點(diǎn)評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確的選擇．在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．
