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.

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.

Winter-swimming has become popular in Beijing. Three years ago, few people would go swimming in the icy waters. But now there is a Winter-swimming Enthusiasts’ Club（冬泳爱好者协会）and it has more than 2,000 members. The oldest is 84 years old and the youngest is only 7. The members are from all walks of life. They may be workers, peasants, soldiers, teachers, students…
Though it is now the coldest part of the season and the water temperature in the city’s lakes is around 0℃, many winter-swimmers still swim in the icy waters, even when it is snowing. They enjoy themselves in the lake, while the people by the side of the lake are wearing heavy clothes.
Why are so many people interested in winter-swimming? Because winter-swimming can be good for one’s health.
Bei Sha is a good example. He is 69, and he once suffered from（患……病）heart trouble for 26 years. After ten years of winter-swimming he is now in good health. Scientists are now studying the effects of winter-swimming on health.
【小题1】 Among the winter-swimmers the oldest man is_______ years older than the youngest one.

A．they are not afraid of coldness

B．they often swim in the icy waters

C．they know that they can benefit（得益）from it

D．winter-swimming can make people healthy

C
Geniuses amaze us, impress us and make us all a little jealous．How do they differ from the average person? Scientists are working hard to figure out that answer．Tune in to the National Geographic Channel to find out about the discoveries they’re making in the series My Brilliant Brain.
When Marc Yu was only two years old, he began to play the piano．After a year, he started learning pieces by Beethoven．Now he’s a world-famous concert pianist at age eight．He learns newer and more difficult pieces with ease and can identify any note he hears．He seems to be specially designed for music．In Born Genius, National Geographic looks at the science behind child prodigies (神童) to explain why some children seem to be born without limits.
Genius didn’t come naturally to Tommy McHugh．His came only after he nearly died from bleeding in his brain．After recovering, McHugh’s head was filled with new thoughts and pictures．So, he began to express them in the form of poetry and art．Now, he’s a seemingly unstoppable creative machine．Sufferers of autism and brain injury have shown that great mental ability can sometimes come from damage or disease．Accidental Genius explores this puzzling relationship.
Can normal people be trained to be geniuses? Susan Polger has shown no signs of extraordinary intelligence．Yet, during her childhood, she studied thousands of chess patterns and learned to recognize them immediately．As a result, she was able to beat skilled adult players by age 10 and can now play up to five games at the same time without even seeing the boards．Make Me a Genius examines what it takes to turn an ordinary brain into that of a genius.
If becoming a genius were easy, we’d all be one．Yet, there is much more to super intelligence than simply being born lucky．Learn more about amazing brains this month on National Geographic’s My Brilliant Brain.
