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（頸圈） 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(chǎn) 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．

分析 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了一種新型的擠牛奶的系統(tǒng)-用機器人擠牛奶，介紹了它的優(yōu)缺點．
解答 32．D．細節(jié)理解題．根據(jù)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可知電腦決定了奶牛是否適合擠奶；故選D．
33．C．細節(jié)理解題．根據(jù)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可知奶牛需要兩到四周的時間來學習使用機器人擠奶系統(tǒng)．一旦經(jīng)過訓練，這些奶牛就不再需要人類協(xié)助；故選C．
34．A．細節(jié)理解題．根據(jù)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可知自從Doug得到了機器人擠奶系統(tǒng)，牛奶產(chǎn)量在他的農(nóng)場增加；故選A．
35．B．推理判斷題．根據(jù)最后一段Still，she says the price of robotic milking systems will continue to limit their use可知機器人擠奶系統(tǒng)是受歡迎但是太貴了；故選B．
點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．
