A. 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. The Robot Activity Support System or RAS, uses sensors installed in a WSU smart home to determine where its residents are, what they are doing and when they need assistance with daily activities. It navigates (定位) through rooms and around obstacles to find people on its own, provides video instructions on how to do simple tasks and can even lead its owner to objects like their medication or a snack in the kitchen.RAS bines the convenience of a mobile robot with the activity detection technology of a WSU smart home to provide assistance in the moment, as the need for help is detected, said Bryan Minor, a postdoctoral researcher in the WSU School of Electrical Engineering and Computer Science.4．閱讀理解 You can purchase Bird Friendly certified coffees around the world and protect wildlife and habitat with every cup ”你能在全世界買Bird Friendly 認證的咖啡，每杯都保護野生動物和棲息地，故選C。 （4）考查推理判斷。根據(jù)第三段中的“ The wood and fruit trees on shade coffee farms provide farmers with additional ine.故選A。根據(jù)第二段中的“ 根據(jù)第一段中的“ In order to deal with severe population and habitat loss, Smithsonian scientists created the Bird Friendly certification. ”可知，科學(xué)家們重視咖啡生長地的問題，并以想出應(yīng)對辦法，故選D。Donate to coffee farmers.【答案】 （1）D（2）A（3）B（4）C 【解析】【分析】本文是一篇說明文，為了應(yīng)對嚴重的遷徙鳥類的數(shù)量和棲息地損失，史密森尼的科學(xué)家創(chuàng)造了 the Bird Friendly certification 。Order coffee online.C.Consume less coffee.D.By selling fruits and wood from trees.C.They are grown on unpolluted land.（3）How can Bird Friendly farmers earn more money? A.They have a strange flavor.C.s a characteristic of Bird Friendly coffees? A.Farmers have been aware of environment protection.D.One fourth of them have destroyed forest habitat for birds.B. Buying Bird Friendly supports the Smithsonian Migratory Bird Center39。 Bird Friendly coffees are shadegrown, meaning the coffee is planted under trees, rather than on the land that has been cleared of all other plants. Coffee experts say shadegrown coffees taste better, because the beans ripen slower than coffee grown in the full sun, resulting in a richer, more plex flavor. Bird Friendly certified coffees grow under biodiverse shade that provides habitat for migratory songbirds and other wildlife, stores carbon and fights climate change. Bird Friendly coffees are also certified organic, meaning they are grown without pesticides, which is better for people and for the planet.
