Question

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 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(家畜) 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 pig producers，grain farmers，potato farmers，and dairy fanners. 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 mod?ern 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 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 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 change of the farm is far in the future,but engineers expect that some robots will be used before long.

4. A主旨大意題。根據(jù)文體特征和全文的展開脈絡(luò)，可以確定首段的首句為本文的大意歸納句。第二段的首句僅描述了未來(lái)農(nóng)場(chǎng)的經(jīng)營(yíng)方式，沒有包括下文談到的古代農(nóng)場(chǎng)依靠馬力(horse power) ,現(xiàn)代農(nóng)場(chǎng)依靠機(jī)械力(machine power) ; 第一段的最后一句僅介紹了今天的農(nóng)場(chǎng)經(jīng)營(yíng)方式，所以，C項(xiàng)與B項(xiàng)均以偏概全；D項(xiàng)雖然涉及了從古到今的農(nóng)耕方式，但側(cè)重點(diǎn)放到了未來(lái)的農(nóng)場(chǎng)經(jīng)營(yíng)方式，所以，也有失偏頗。

5. C細(xì)節(jié)理解題。見第二段第三句。

6. B事實(shí)判斷題。第一段和第二段的最后一句分別對(duì)今天的農(nóng)耕方式進(jìn)行了說(shuō)明。A項(xiàng)中的totally過(guò)于絕對(duì)；C項(xiàng)表述與事實(shí)不符，文中也未提到；文章第二段倒數(shù)第二句只是提到農(nóng)業(yè)大學(xué)的學(xué)生被要求學(xué)習(xí)計(jì)算機(jī)課程，并未說(shuō)"they can do nothing without the help of computers on today' s farms"。所以，D項(xiàng)表述與原文不符。

7. C主旨大意題。盡管全文濃墨重彩地談到未來(lái)農(nóng)業(yè)的經(jīng)營(yíng)方式，但全文主旨應(yīng)是農(nóng)業(yè)發(fā)展的歷程。
