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.

材料一：1524年，有位西班牙人这样说：“以前我们在世界的边缘，现在在它的中央了，这给我们的命运带来了前所未有的改变。”

——〈西方文明史〉

材料二：哥伦布没有到达印度，但他发现了至关重要的贵金属。据经济史权威估计，从1493年到1800年世界白银产量的85%和黄金产量的70%来自拉丁美洲。美洲白银生产在16世纪约为17000吨，到7世纪约为42000吨，其中由31000吨运抵欧洲。欧洲又将40%运往亚洲。……美洲白银18世纪产量约为74000吨，其中52000吨运往欧洲，其中40%约20000吨运往亚洲。另外留在美洲本土的白银约有3000吨横渡太平洋经马尼拉运抵中国。如果再加上日本和其他地方生产的白银，全球白银产量的一半最终抵达亚洲，尤其是中国和印度。

——弗兰克《白银资本》序

材料三：哥伦布发现美洲以及接踵来的葡萄牙人、英国人、法国人等，通过对新土地的殖民和占有，与土著居民的接触、交往和融合给欧洲人送去了新世界的文明，还使新旧大陆的物产得以交换和传播……

东西两半球的不同文化圈的大汇合，加速了人类从传统农耕文明向现代工业文明转变的过程。……没有美洲贡献的大量金银与物质财富，没有北美的自由移民垦殖区，西方资本主义的发展将会缓慢得多，英国也不可能成为发动工业革命的国家……没有把世界连成整体的世界大革命，也不可能推动否定传统的思想解放运动。
