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.

Recently some American scientists have given a useful piece of advice to people in industrialized nations.They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago.   

       The scientists say that the human life has changed greatly.Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses.      So they are called "diseases of civilization".Many cancers and diseases of the blood system are examples of such diseases.

       Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none.     However, a change in food is one of the main differences between life in ancient times and that of today.

       Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones.They ate a lot of fresh wild vegetables and fruits.They did not have milk or any other dairy products, and they made very little use of grains.     We eat six times more salt than our ancestors.We eat more sugar.We eat twice as much fat but only one third as much protein and much less vitamin C.

           But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

       A.Stone Age people lived a simple life.

       B.But today, we enjoy eating a lot of these.

       C.In that case, they would live much healthier.

       D.Ancient people also got lots of physical exercise.

       E.These new sicknesses were not known in ancient times.

       F.People today probably don't want to live like our ancestors.

       G.Modern people used to suffer from "diseases of civilization".
