Currently, an estimated 50 percent of adults over the age of 85 need assistance with every day activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearly $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. 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。Through sensors.B.Through a mobile robot.Through their daily activities.（2）What can we know about RAS? A.B.It can locate people and do any task.D.s Minor39。Doubtful.B.Optimistic.D.Elderly people leave the nursing home.Smart Home Tests first elderCare robot.C.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(xué)的科學(xué)家們研發(fā)的機(jī)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。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(jī)器人活動(dòng)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?cè)谧鍪裁匆约昂螘r(shí)需要日常活動(dòng)的幫助，說明傳感器起到了重大的作用，故選A。根據(jù)最后一段中的“The next step in the research will be to test RAS39。 （3）考查推理判斷。 （4）考查主旨大意。再根據(jù)最后一段中的“The next step in the research will be to test RAS39。 【點(diǎn)評(píng)】本題考點(diǎn)涉及細(xì)節(jié)理解，推理判斷和主旨大意三個(gè)題型的考查，是一篇科技類閱讀，考生需要準(zhǔn)確捕捉細(xì)節(jié)信息，同時(shí)根據(jù)上下文進(jìn)行邏輯推理，概括歸納，從而選出正確答案。 Some years ago, MichelAndre found himself staring at the body of a dead whale on a beach in the Canary Islands. It was obvious that the animal had been struck violently by a ship——but why? Only later, after surveying the whales which lived in the area and measuring the increase of sound pollution from ships did it bee clear that there was a link. Andre has spent 20 years developing an advanced system to better understand why incidents like this happen. His underwater microphones have exposed a world of deafening sound and animal munication never observed with such clarity(清晰) before.t travel through water in the uniform, predictable way they do through the air. Instead, the temperature, salinity (鹽度) and, flow of water have great effects on their path.s also possible to slow ships down to 18km/h or less, which is less likely to seriously injure a whale.s International Maritime Organisation has already published guidelines on how to quieten ships, but it will be a while before the effects of such changes might be observed.Stubborn.Flexible.Dull.Friendly.（2）What39。To lower the speed of ships.B.To set up preserves under the sea.D.s attitude towards what Michel Andre has done?
