It navigates (定位) through rooms and around obstacles to find people on its own, provides video instruction on how to do simple tasks and can even lead its owners 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.Currently about 50 percent adults over the age of 85 need assistance with everyday activities such as preparing meals and taking medication and the annual cost for this assistance in the US is nearby $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 pressure on the healthcare system by making it easier for older adults to live alone.RAS is the first robot researchers have tried to apply to their smart home environment. They recently published a study in the journal Cognitive Systems Research that shown 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 RAS’s performance with a group of older adults to get a better data of what video reminders and other performances they have regarding the robot.”32. What plays a key role in RAS serving the elderly?A. Sensors B. Videos. C. Signal lights D. Head size33. What can we learn 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.34. What’s Minor’s attitude toward the future of RAS?A. Doubtful B. Negative C. Optimistic D. Uncertain35. What would be a suitable title for the text?A. Elderly People Leave the Nursing Home.B. Smart Home Tests First Elder Care RobotC. RAS, the First Robot to Make Home Smart.D. Older Adults Have Benefited from RAS a Lot.第二節(jié)：（共5小題；每小題2分，滿(mǎn)分10分）根據(jù)短文內(nèi)容，從短文后的選項(xiàng)中選出能填入空白處的最佳選項(xiàng)。 I have that confidence now. I am equal to those I once saw as better than me.A name shouldn’t make such a difference, but sometimes, when a person finds his or her True Name, they develop a new shine visible to friends, family and especially themselves.I can’t always be Bo. Sometimes exposing myself is still scary and I feel too nervous。 it’s the name that is as unique and memorable as I am.People usually know me as Christine. They still see me as a quiet, bookish child. They don’t know who I am now. My most recent hopes, fears, goals, dreams and opinions escape their notice。 2 weeks $550。 2 wee
