【正文】 gam says a smile may be one way to help. He tells his patients to smile 20 times an hour. To some, that might seem like a lot of smiling. Or some might even feel foolish ... smiling for seemingly no reason. But a smile does not involve drugs. It is not invasive like a surgical operation. It is free and it has no bad side effects. However, when we are stressed for a long period, these stress hormones are everpresent in our bodies. And that, medical researchers warn, may lead to health problems.When you feel stressed or under pressure, your body releases many natural hormones (荷爾蒙) including adrenaline and cortisol. Adrenaline increases your heart rate and blood pressure. Cortisol is the body39。 Experts note that an unhealthy lifestyle can put you at great risk of heart disease and stroke. So doctors urge us to eat healthy foods, get exercise, stop smoking and limit our alcohol intake. But there is something else you can do. And it is free and easy. Smile! 【點(diǎn)評】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。再根據(jù)最后一段中的“The next step in the research will be to test RAS39。 （4）考查主旨大意。 （3）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。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(shí)需要日?；顒拥膸椭?，說明傳感器起到了重大的作用，故選A。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。Smart Home Tests first elderCare robot.C.Elderly people leave the nursing home.D.Optimistic.B.Doubtful.s Minor39。D.It can locate people and do any task.B.Through their daily activities.（2）What can we know about RAS? A.Through a mobile robot.B.Through sensors. 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。 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. A robot created by Washington State University (WSU) scientists could help elderly people with dementia (癡呆) and other limitations live independently in their own homes. 【點(diǎn)評】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，是一篇科研類閱讀，要求考生在捕捉細(xì)節(jié)信息的基礎(chǔ)上，進(jìn)一步根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。 （4）考查主旨大意。他說，表演不僅僅是 假裝 成某個(gè)人，它還包括文本和語言的體現(xiàn)。根據(jù)最后一段中的“However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than ‘pretending’由此可知Brown博士的研究發(fā)現(xiàn)，演員在表演時(shí)大腦活動是不同的，故選B。根據(jù)倒數(shù)第三段中的“The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some thirdperson knowledge or inferences about their character.”結(jié)果顯示，大腦活動的不同取決于所測試的情境。根據(jù)第五段中的“Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party?”一旦進(jìn)入核磁共振掃描儀，演員們被要求回答一系列問題，比如:他們會去參加派對嗎?由此推斷出Brown博士的團(tuán)隊(duì)是通過掃描一些演員的大腦活動進(jìn)行他們的研究的，故選A。現(xiàn)在，研究人員表示，演員的大腦活動模式不同，取決于他們是否扮演角色。A research on the brain activity of actors.D.A debate of how the brain functions.B.D.C.B. brain activity is more active when they are in character.（3）How did Philip Davis react to the research?

However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than pretending to be someone — it involves embodying (體現(xiàn)) the text and language.（1）How did Dr Brown39。 The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some thirdperson knowledge or inferences about their character. Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party? And would they tell their parents that they had fallen in love? almost like the character is possessing you. Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not. Acting is the least mysterious of all crafts, Marion Brando once said. But for scientists, working out what is going on in an actor39。 【點(diǎn)評】本題考點(diǎn)涉及推理判斷和主旨大意兩個(gè)題型的考查，是一篇科普類閱讀，要求考生根據(jù)上下文的邏輯關(guān)系，進(jìn)行分析，推理，概括和歸納，從而選出正確答案。 （4）考查主旨大意。亞歷山大，一個(gè)出身于186年的澳大利亞演員，在年輕的時(shí)候聲音出了問題。 （3）考查推理判斷。 （2）考查推理判斷。根據(jù)第一段中的“I was brought up to think that the preferred way of dealing with aches is to do nothing and hope they39。People with back pain are victims of inappropriate postures.【答案】 （1）D（2）D（3）A（4）C 【解析】【分析】本文是一篇說明文，介紹亞歷山大技巧的對于矯正身體的作用以及其發(fā)明者。Alexander improved the technique to treat body pain.C.He had to leave home to develop his technique.（4）What is the main idea of the passage?
