improve the quality of life for humans.Alan Beck，an expert in humananimal relationship，and Nancy Edwards，a professor of nursing，are leading the animalassisted study concerning the influence of robotic dogs on old peoples depression，physical activity，and life satisfaction.“No one will argue that an older person is better off being more active，challenged，or stimulated(刺激)，”Edwards points out.“The problem is how we promote(使成為現實)that，especially for those without friends or help.A robotic dog could be a solution.”In the study，the robot，called AIBO，is placed for six weeks in the houses of some old people who live alone.Before placing AIBO in the home，researchers will collect baseline data for six weeks.These old people will keep a diary to note their feelings and activities before and after AIBO.Then，the researchers will review the data to determine if it has inspired any changes in the life of its owner.“I talk to him all the time，and he responds to my voice，”says a seventyyearold lady.“When Im watching TV，hell stay in my arms until he wants down.He has a mind of his own.”The AIBOs respond to certain orders.The researchers say they have some advantages over live dogs，especially for old people.Often the elderly are disabled and cannot care for an animal by walking it or playing with it.A robotic dog removes exercises and feeding concerns.“At the beginning，it was believed that no one would relate to the robotic dog，because it was metal and not furry.”Beck says.“But its amazing how quickly we have given up that belief.”Hopefully，down the road，these robotic pets could become a more valuable health helper.They will record their masters blood pressure，oxygen levels，or heart rhythms.AIBOs may even one day have games that can help stimulate old peoples minds.1The purpose of Beck and Edwards study is to_.Aunderstand humananimal relationshipBmake lonely old peoples life betterCfind the causes of old peoples lonelinessDpromote the animalassisted research解析：選B。依據第一段開頭“.to determine whether they can improve the quality of life for humans.”可以得出答案。2In the research，the old people are asked to_.Anote the activities of AIBOsBkeep AIBOs at home for 12 weeksCrecord their feelings and activitiesDanalyze the collected information解析：選C。依據第二段“These old people will keep a diary to.”可知。3What is the advantage of AIBO over live dogs?AIt is easier to keep at home.BIt can help the disabled people.CIt responds to all the human orders.DIt can watch TV with its owner.解析：選A。從文章第四段“.some advantages.removes exercises and feeding concerns.”可以知道答案。4The author seems to suggest that the future robotic dogs may_.Acure certain diseasesBkeep old people activeCchange peoples beliefsDlook more like real dogs解析：選B。從文章的最后一句“.stimulate old peoples minds.”可得出答案。5According to the passage，which of the following statements is TRUE?AThe professors are leading the animalassisted study concerning old peoples life.BThe AIBOs will always listen to their owners without their own minds.CThe researchers will know from the data whether AIBO can help its owner.DAIBOs can have games with the old people to stimulate their minds.解析：選C。從文章第一段可以知道這個研究是關注機器狗對老人們生活的影響，而不是關注老人們的生活，所以A是錯的；從文章第三段“He has a mind of his own.”得知B項也不對；文章最后一句“AIBOs may even one day.”說明D項提到的現在還沒有實現；從文章第二段最后一句可以知道C項是正確的。.信息匹配閱讀下面6款數碼產品的介紹，并按照要求匹配信息。以下是不同款式數碼產品的介紹：ACool Design MP4 Player1GB1.8Inch ScreenVery coollooking MP4 Player，Combining 65,000 OLED screen，easy to use
