问题描述：
Scientists are placing robotic (机器人的) dogs in the homes of lonely old people to test whether they can improve the quality of life for humans.Alan Beck,an expert in human-animal relationship,and Nancy Edwards,a professor of nursing,are leading the animal assisted study on the effect of robotic dogs on old people's depression (沮丧),physical activity,and life satisfaction
In the study,the robot,called AIBO,is placed for six weeks in the houses of old people who live alone.Before placing AIBO in the home,scientists will collect baseline data (数据) for six weeks.These old people will keep a diary to note their feelings and activities before and after AIBO.Then,the scientists will review the data to test if it has produced any changes in the life of its owner.
"I talk to him all the time,and he responds (应答) to my voice," says a seventy-year-old lady."When I'm watching TV,he'll stay in my arms until he wants down.He has a mind of his own." The AIBOs respond to certain orders.The scientists 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 exercise and feeding.
"At the beginning,it was believed that no one would keep the robotic dog,because it was metal and not furry," Beck says."Hopefully,down the road,these robotic pets could become a more valuable health helper.They will record their masters' blood pressure (血压),oxygen levels or heart rhythms (心律).AIBOs may even one day have games that can help stimulate (刺激) older people's minds."
( )71.The purpose of Beck and Edwards' study is to _____.
A.understand human-animal relationship
B.make lonely old people's life better
C.find the causes of old people's loneliness
D.improve the animal-assisted research
( )72.In the research,the old people are asked to _____.
A.note the activities of AIBOs
B.keep AIBOs at home for 12 weeks
C.record their feelings and activities
D.study the collected information
( )73.What phrase can we use instead of the underlined word removes?
A.moves again B.is movable C.doesn't need D.need
( )74.What is the better point of AIBO than live dogs?
A.It is easier to keep at home.
B.It can help the disabled people.
C.It reponds to all the human orders.
D.It can watch TV with its owner.
( )75.The author seems to suggest that the future robotic dogs may _____.
A.cure certain illnesses B.keep old people active
C.change people's ideas D.look more like real dogs
