Technology is making life easier for some dairy farmers．They use robotic systems to milk their cows．These systems are designed to reduce labor and increase milk production．
Cows are trained to follow a series of paths that lead to the milking stations．Only one cow at a time can enter the station．Once inside, the cow is rewarded with food．As the cow eats, a robotic arm cleans and connects the animal to the milking machine．A few minutes later, the milking is completed．The gate is lifted．The cow leaves and the next cow enters．The robotic systems are designed to operate twenty-four hours a day．Cows are milked on average about three times a day．Some are milked four to six times a day．The cows wear collars(颈圈)around their necks that identify them to the system．A computer keeps records on their eating and milking．A cow is released from the station if the computer decides it should not be milked．The system also measures the temperature and color of the freshly produced milk．Milk is thrown away if it does not pass the tests．Cows need two to four weeks to learn to use the robotic milking systems．Once trained, the cows no longer require human assistance, unless something goes wrong．
Professor Plaut heads the Department of Animal Science at Michigan State University．She believes the systems will attract especially the next generation of farmers who are more interested in technology and less interested in working all the time on the farm．Still, she says the price of robotic milking systems will continue to limit their use．Doug Suhr has more than one hundred milking cows on his farm．Last year it became the fourth farm in southeast Minnesota to get a robotic milking system．A recent story in a local agricultural newspaper said the first robot cost ＄175,000 and the second cost ＄150,000．Doug says the increase in milk production reaches a high of more than 6 kg per cow per day．

One of the goals of American education officials is to have all public schools connected to the Internet computer system and have computer for all students．Government studies show that in 1994 only thirty-five percent of American public schools were connected to the Internet．Last year, that number reached eighty-nine percent．
Virginia Polytechnic Institute of State University is a large university in the southern state of Virginia．Officials at Virginia Tech say computers are very important to a student’s education．All students at Virginia Tech have been required to have a computer since 1998．
Each student’s living area at Virginia Tech has the necessary wires to link a computer to the Internet．The students can send and receive electronic mail, use the World Wide Web part of the Internet and link with other universities, all without leaving their room．They can also use their computers to send electronics copies of their schoolwork to their teachers．And they can search for books in the school’s huge library．
Most major American universities and colleges strongly urge or require new students to have a computer．Most colleges and universities also have large rooms where students can use computers for class work．
American high schools also have computers．Many have their own areas on the World Wide Web．If you have a computer you can learn about Fremont Union High School in Sunnyvale, California, for example．Its Web site provides information about the school, the teachers and their electronic mail addresses．It also lists student events and organizations．
Young children also use computer in school．Smoketree Elementary School in Lake Havasu, Arizona has given us a good example．The school also has a World Wide Web site．It tells about the school and the teachers and has a area for young children．These young children use computer in school to learn numbers and letters．They also learn how to use the computer they will need later in their education．
