7．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 175，000andthesecondcost150，000．Doug says the increase in milk production reaches a high of more than 6kg per cow per day．
32．Under robotic milking systems，Ddecide（s） whether a cow is suitable to be milked．
A．the robotic arms
B．the dairy farmers
C．the cows themselves
D．a computer
33．When is human assistance needed during the milking？C
A．When the cows enter the milking station every morning．
B．When a robotic arm connects a cow to the milking machine．
C．When the cows are trained to use the robotic milking system in the first two to four weeks．
D．When the temperature and color of the freshly produced milk are measured．
34．Which of the following statements is TRUE according to the last paragraph？A
A．Since Doug got the robotic milking system，milk production on his farm has increased．
B．The price of milking machines decreases $25，000 every year．
C．Doug has the largest farm in southeast Minnesota．
D．There are four farms in southeast Minnesota that have robotic milking systems so far．
35．It can be inferred from the passage thatB．
A．the price of robotic milking systems will greatly decrease
B．robotic milking systems are still too expensive to be popular
C．most farmers are too old to use robotic milking systems
D．robotic milking systems don't need to work at night．
分析 本文属于说明文阅读，作者通过这篇文章主要向我们描述了一种新型的挤牛奶的系统-用机器人挤牛奶，介绍了它的优缺点．
解答 32．D．细节理解题．根据第二段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可知电脑决定了奶牛是否适合挤奶；故选D．
33．C．细节理解题．根据第二段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可知奶牛需要两到四周的时间来学习使用机器人挤奶系统．一旦经过训练，这些奶牛就不再需要人类协助；故选C．
34．A．细节理解题．根据最后一段A recent story in a local agricultural newspaper said the first robot cost 175，000andthesecondcost150，000．Doug says the increase in milk production reaches a high of more than 6kg per cow per day可知自从Doug得到了机器人挤奶系统，牛奶产量在他的农场增加；故选A．
35．B．推理判断题．根据最后一段Still，she says the price of robotic milking systems will continue to limit their use可知机器人挤奶系统是受欢迎但是太贵了；故选B．
点评 考察学生的细节理解和推理判断能力，做细节理解题时一定要找到文章中的原句，和题干进行比较，再做出正确的选择．在做推理判断题不要以个人的主观想象代替文章的事实，要根据文章事实进行合乎逻辑的推理判断．
