【文章內(nèi)容簡(jiǎn)介】 ption that one mon feature of Alzheimer39。s disease is a damaged awareness of illness. And they wanted to prove their theory that the lack of awareness can be used to predict whether someone with mild cognitive（認(rèn)知的）damage will progress to fullon AD. For the study, mild cognitive damage was defined as someone whose mental state was considered healthy but who had either plained of memory loss or had suffered objective memory loss. The researchers used existing data for 1, 062 people between the ages of 55 and 90 that had been recorded over a 12year period. The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an objective marker of the sort of reduced brain function that goes along with expected, glucose uptake was reduced in those with AD. What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness. Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.（1）What can be implied from paragraph 1？ A.People can be forgetful at different ages.B.The memory of the young is better than the old.C.Old people are most afraid of getting Alzheimer39。s disease.D.It39。s a rare phenomenon when young people forget something.（2）What statement does the researchers in the new study agree with? A.Being aware all the time is a fearful thing.B.Illness awareness has nothing to do with Alzheimer39。s disease.C.Recognizing forgetfulness doesn39。t mean developing Alzheimer39。s disease.D.Realizing forgetfulness must be a sign of developing Alzheimer39。s disease.（3）What can be a sign of developing Alzheimer39。s disease? A.Realizing others39。 forgetfulness.B.Reduced uptake of glucose.C.Having higher intake of glucose.D.Expected increase in brain function.（4）From which is the text probably taken? A.Science fiction.B.A chemistry book.C.A science research.D.A health brochure.【答案】 （1）A（2）C（3）B（4）C 【解析】【分析】本文是一篇說(shuō)明文，介紹了如何預(yù)測(cè)你的記憶喪失是否是老年癡呆癥,一項(xiàng)新的研究表明，不是遺忘，而是沒(méi)有意識(shí)到我們的健忘讓人們感到害怕。 （1）考查推理判斷。根據(jù)第一段中的“In our twenties, we find it funny when we can39。t remember our neighbor39。s cat39。s name or a handsome actor who starred in a famous movie.

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. 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. 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 tas
