【正文】 $2 trillion. With the number of adults over 85 expected to triple by 2050, researchers hope that technologies like RAS and the WSU smart home will relieve some of the financial strain on the healthcare system by making it easier for older adults to live alone. RAS is the first robot researchers have tried to incorporate into their smart home environment. They recently published a study in the journal Cognitive Systems Research that demonstrates how RAS could make life easier for older adults struggling to live independently. While we are still in an early stage of development, our initial results with RAS have been promising, Minor said. The next step in the research will be to test RAS39。 performance with a group of older adults to get a better idea of what prompts, video reminders and other preferences they have regarding the robot.（1）How does RAS serve elderly people? A.Through sensors.B.Through objects.C.Through a mobile robot.D.Through their daily activities.（2）What can we know about RAS? A.It is the first robot used in daily life.B.Its function remains to be tested.C.It can locate people and do any task.D.It can cook for owners on its own.（3）What39。s Minor39。s attitude toward the future of RAS? A.Doubtful.B.Negative.C.Optimistic.D.Uncertain.（4）What can be a suitable title for the text? A.Elderly people leave the nursing home.B.Smart Home Tests first elderCare robot.C.RAS, the first robot to make home smart.D.Older adults have benefited from RAS.【答案】 （1）A（2）B（3）C（4）B 【解析】【分析】本文是一篇說明文，介紹了一款由美國華盛頓州立大學的科學家們研發(fā)的機器人，可以幫助那些癡呆或有身體缺陷的老年人在家里過上自立的生活。 （1）考查細節(jié)理解。根據(jù)章第二段中的“ The Robot Activity Support System, or RAS, uses sensors （傳感器）equipped in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities”可知機器人活動支持系統(tǒng)（RAS）使用WSU智能家居中配備的傳感器（傳感器）來確定其居民在哪里，他們在做什么以及何時需要日常活動的幫助，說明傳感器起到了重大的作用，故選A。 （2）考查推理判斷。根據(jù)最后一段中的“The next step in the research will be to test RAS39。 performance…”可知，這臺機器人的表現(xiàn)還要經過進一步的測，說明正在測試階段，故選B。 （3）考查推理判斷。根據(jù)最后一段中的“ While we are still in an early stage of development, our initial results with RAS have been promising”可知，Minor對這款機器人的未來發(fā)展充滿信心、非常樂觀，故選C。 （4）考查主旨大意?？v觀全文可知，本文介紹了一款由美國華盛頓州立大學的科學家們研發(fā)的機器人。再根據(jù)最后一段中的“The next step in the research will be to test RAS39。 performance ”可知，機器人目前還在華盛頓州立大學的智能屋里進行測試，故選B。 【點評】本題考點涉及細節(jié)理解，推理判斷和主旨大意三個題型的考查，是一篇科技類閱讀，考生需要準確捕捉細節(jié)信息，同時根據(jù)上下文進行邏輯推理，概括歸納，從而選出正確答案。6．閱讀理解 A new study suggests a link between exposure to greenery and reduced desires for alcohol cigarette and junk food. The study is the first to investigate the possible relationships between exposure to nature and desires and negative emotions. Researchers at the University of Plymouth39。s School of Psychology surveyed 149 respondents (應答者) aged 21 o 65 about the proportion( 比例 )of green space in their neighborhood, the presence of green views from their home, their access to a garden and how often they use public green space. The study also asked questions about experiences with depression and anxiety, as well as desires for things like caffeine, alcohol and nicotine. Participants rated the intensity( 強度), imagery, and intrusiveness(侵擾性) of their desires on an 11point scale. Researchers found the presence of visible green space contributed to decreased desires for junk food. The effect was particularly noticeable when more than 25 percent of a respondent39。s view was greenery. Previous scholarship(學術研究) has dealt mostly with exercise in nature: A 2015 study out of the University of Michigan found 90 minute group nature walks were effective at batting depression and relieving other mood disorders. But for people who struggle with accessibility or don39。t have time for a 90minute walk, this new study suggests just looking out a window at a tree can help fight off a bad habit. It has been known for some time that being outdoors in nature is linked to a person39。s wellbeing, lead author Leanne Martin said in a statement. But for there to be a similar association with desires from simply being able to see green space adds a new dimension to the previous research. A 2018 study from Denmark39。s Aarhus University for example, found that. Having access to green space throughout childhood decreased a person39。s risk of developing mental health problems as an adult.（1）What does the second paragraph mainly talk about? results of the new study. purpose of the new study. significance of the new study. content of the new study.（2）What does the underlined word batting in paragraph 4 probably mean? ...（3）According to the passage, the new study _____. referred to exercise in nature enriched the previous research to some degree carried out by the University of Michigan exposure to greenery helped cure mental problems（4）n which section of a newspaper may this passage appear? World amp。Science【答案】 （1）D（2）A（3）B（4）C 【解析】【分析】本文是一篇說明文，介紹了一項新的研究成果多看綠色植物和吃垃圾食品這兩者看似風馬牛不相及，可研究結構卻表明它們之間存在著一種奇妙的關系：多看綠色植物能幫助人們克制吃垃圾食品的欲望。 （1）考查段落大意。根據(jù)第二段中的“Researchers …surveyed 149 respondents aged 21 o 65 about the proportion of green space in their neighborhood…”研究人員調查了年齡在21~65歲之間的149名參與者小區(qū)內的綠植比例……；以及“The study also asked questions about experiences with depression and anxiety…”研究中還問了與抑郁及焦慮有關
