Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.Fellow Robots is one company bringing social robots to the market. The company's "Oshbot" robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. "We have technologies to train social robots to do things not for us, but with us, " said Breazeal.(1) How are social robots different from household robots?A. They can control their emotions.B. They are more like humans.C. They do the normal housework.D. They respond to users more slowly.(2) What can a Jibo robot do according to Paragraph 3?A. Communicate with you and perform operations.B. Answer your questions and make requests.C. Take your family pictures and deliver milk.D. Obey your orders and remind you to take pills.(3) What can Oshbot work as?A. A language teacher.B. A tour guide.C. A shop assistant.D. A private nurse.(4) We can learn from the last paragraph that social robots will.A. train employeesB. be our workmatesC. improve technologiesD. take the place of workers(5) What does the passage mainly present?A. A new design idea of household robots.B. Marketing strategies for social robots.C. Information on household robots.D. An introduction to social robots.19、【来源】 2015年高考真题天津卷第19题2017~2018学年12月河南洛阳洛龙区洛阳市第一高级中学高二上学期月考第21~25题10分2017~2018学年陕西西安雁塔区陕西师范大学附属中学高三上学期开学考试第24~28题10分One day when I was 12, my mother gave me an order: I was to walk to the public library, and borrow at least one book for the summer. This was one more weapon for her to defeat my strange problem—inability to read.In the library, I found my way into the "Children's Room."I sat down on the floor and pulled a few books off the shelf at random. The cover of a book caught my eye. It presented a picture of a beagle. I had recently had a beagle, the first and only animal companion I ever had as a child. He was my secret sharer, but one morning, he was gone, given away to someone who had the space and the money to care for him. I never forgot my beagle.There on the book's cover was a beagle which looked identical to my dog. I ran my fingers over the picture of the dog on the cover. My eyes ran across the title, Amos, the Beagle with a Plan. Unknowingly, I had read the title. Without opening the book, I borrowed it from the library for the summer.Under the shade of a bush, I started to read about Amos. I read very, very slowly with difficulty. Though pages were turned slowly, I got the main idea of the story about a dog who, like mine, had been separated from his family and who finally found his way back home. That dog was my dog, and I was the little boy in the book. At the end of the story, my mind continued the final scene of reunion, on and on, until my own lost dog and I were, in my mind, running together.My mother's call returned me to the real world. I suddenly realized something: I had read a book, and I had loved reading that book. Everyone knew I could not read. But I had read it. Books could be incredibly wonderful and I was going to read them.I never told my mother about my "miraculous"（奇迹般地）experience that summer, but she sawa slow but remarkable improvement in my classroom performance during the next year. And years later, she was proud that her son had read thousands of books, was awarded a PhD in literature, and authored his own books, articles, poetry and fiction. The power of the words has held.(1) The author's mother told him to borrow a book in order to.A. encourage him to do more walkingB. let him spend a meaningful summerC. help cure him of his reading problemD. make him learn more about weapons(2) The book caught the author's eye because.A. it contained pretty pictures of animalsB. it reminded him of his own dogC. he found its title easy to understandD. he liked children's stories very much(3) Why could the author manage to read the book throughA. He was forced by his mother to read it.B. He identified with the story in the book.C. The book told the story of his pet dog.D. The happy ending of the story attracted him.(4) What can be inferred from the last paragraph?A. The author has become a successful writer.B. The author's mother read the same book.C. The author's mother rewarded him with books.D. The author has had happy summers ever since.(5) Which one could be the best title of the passage?A. The Charm of a BookB. Mum's Strict OrderC. Reunion with My BeagleD. My Passion for Reading20、【来源】 2015年高考真题天津卷第20题DOnce when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I've ever had: Be bold and brave — and mighty (强大的) forces will come to your aid.Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.Boldness means a decision tobite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas —even physical strength greater than most of us realize.Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. “In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,” said Tim. “I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet — and stopped him cold.”Boldness — a willingness to extend yourself to the extreme—is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.So, always try to live a little bit beyond your abilities—and you'll find your abilities are greater than you ever dreamed.(6) Why was the author sometimes unable to reach his goal in the past?A. He faced huge risks.B. He lacked mighty forces.C. Fear prevented him from trying.D. Failure blocked his way to success.(7) What is the implied meaning of the underlined part?A. Swallow more than you can digest.B. Act slightly above your abilities.C. Develop more mysterious powers.D. Learn to make creative decisions.(8) What was especially important for Tim’s successful defense in the football game?A. His physical strength.B. His basic skill.C. His real fear.D. His spiritual force.(9) What can be learned from Paragraph 5?A. Confidence grows more rapidly in adults.B. Trying without success is meaningless.C. Repeated failure creates a better life.D. Boldness can be gained little by little.(10) What is the author’s purpose in writing this passage?A. To encourage people to be courageous.B. To advise people to build up physical power.C. To tell people the ways to guarantee success.D. To recommend people to develop more abilities.四、任务型阅读21、【来源】 2015年高考真题天津卷第21题Six days a week, up and down the red hills of northeast Georgia, my grandfather brought the mail to the folks there. At age 68, he retired from the post office, but he never stopped serving the community.On his 80th birthday, I sent him a letter, noting the things we all should be thankful for — good health, good friends and good outcomes. By most measurements he was a happy man. Then I suggested it was time for him to slow down. At long last, in a comfortable home, with a generous pension, he should learn to take things easy.“Thank you for your nice words,” he wrote in his letter back, “and I know what you meant, but slowing down scares me. Life isn't having it made; it's getting it made.”“The finest and happiest years of our lives were not when all the debts were paid, and all difficult experiences had passed, and we had settled into a comfortable home. No. I go back years ago, when we lived in a three-room house, when we got up before daylight and worked till after dark to make ends meet.I rarely had more than four hours of sleep. But what I still can't figure out is why I never got tired, never felt better in my life. I guess the answer is, we were fighting for survival, protecting and providing for those we loved. What matters are not the great moments, but the partial victories, the waiting, and even the defeats. It's the journey, not the arrival, that counts.”The letter ended with a personal request: “Boy, on my next birthday, just tell me to wake up and get going, because I will have one less year to do things — and there are ten million things waiting to be done.”Christina Rossetti, an English poet, once said: “Does the road wind uphill all the way? Yes, to the very end.” Today, at 96, my grandfather is still on that long road, climbing.(6) What was the author’s grandfather before he retired? (no more than 5 words)(7) What did the author advise his grandfather to do in his letter? (no more than 10 words)(8) What is the grandfather’s view on life according to his letter back? (no more than 10 words)(9) How do you understand the underlined sentence in the last paragraph? (no more than 10 words)(10) Do you agree with the grandfather’s view on life? Give reasons in your own words, (no more than 20 words)五、书面表达22、【来源】 2015年高考真题天津卷第22题假设你是晨光中学学生会主席李津，你校拟向美国友好交流学校的中文班捐赠一批图书。

﹣m=0．由△=（﹣4）2﹣4×3（﹣m ）=16+12m=0，得m=﹣．所以与直线4x+3y ﹣8=0平行且与抛物线y=﹣x 2相切的直线方程为4x+3y ﹣=0．所以抛物线y=﹣x 2上的一点到直线4x+3y ﹣8=0的距离的最小值是=．故选：A ．【点评】本题考查了直线与圆锥曲线的关系，考查了数学转化思想方法，训练了两条平行线间的距离公式，是中档题．3． 【答案】B【解析】解：∵函数f （2x+1）=3x+2，且f （a ）=2，令3x+2=2，解得x=0，∴a=2×0+1=1．故选：B．4．【答案】B【解析】解：若命题“p或q”为真，则p真或q真，若“非p”为真，则p为假，∴p假q真，故选：B．【点评】本题考查了复合命题的真假的判断，是一道基础题．5．【答案】A【解析】解：∵函数f（x）=3﹣|x﹣1|+m的图象与x轴没有交点，∴﹣m=3﹣|x﹣1|无解，∵﹣|x﹣1|≤0，∴0＜3﹣|x﹣1|≤1，∴﹣m≤0或﹣m＞1，解得m≥0或m＞﹣1故选：A．6．【答案】A【解析】解：∵sinB+sin（A﹣B）=sinC=sin（A+B），∴sinB+sinAcosB﹣cosAsinB=sinAcosB+cosAsinB，∴sinB=2cosAsinB，∵sinB≠0，∴cosA=，∴A=，∴sinA=，当sinA=，∴A=或A=，故在△ABC中，sinB+sin（A﹣B）=sinC是sinA=的充分非必要条件，故选：A7．【答案】C【解析】解：如图，++（）．故选C．8．【答案】A【解析】解：∵线段AB在平面α内，∴直线AB上所有的点都在平面α内，∴直线AB与平面α的位置关系：直线在平面α内，用符号表示为：AB⊂α故选A．【点评】本题考查了空间中直线与直线的位置关系及公理一，主要根据定义进行判断，考查了空间想象能力．公理一：如果一条线上的两个点在平面上则该线在平面上．9．【答案】D【解析】解：命题p：∃x∈R，cosx≥a，则a≤1．下列a的取值能使“￢p”是真命题的是a=2．故选；D．10．【答案】D【解析】解：∵g（x）=﹣f（2﹣x），∴y=f（x）﹣g（x）=f（x）﹣+f（2﹣x），由f（x）﹣+f（2﹣x）=0，得f（x）+f（2﹣x）=，设h（x）=f（x）+f（2﹣x），若x≤0，则﹣x≥0，2﹣x≥2，则h（x）=f（x）+f（2﹣x）=2+x+x2，若0≤x≤2，则﹣2≤﹣x≤0，0≤2﹣x≤2，则h（x）=f（x）+f（2﹣x）=2﹣x+2﹣|2﹣x|=2﹣x+2﹣2+x=2，若x＞2，﹣x＜﹣2，2﹣x＜0，则h（x）=f（x）+f（2﹣x）=（x﹣2）2+2﹣|2﹣x|=x2﹣5x+8．作出函数h （x ）的图象如图：当x ≤0时，h （x ）=2+x+x 2=（x+）2+≥，当x ＞2时，h （x ）=x 2﹣5x+8=（x ﹣）2+≥，故当=时，h （x ）=，有两个交点，当=2时，h （x ）=，有无数个交点，由图象知要使函数y=f （x ）﹣g （x ）恰有4个零点，即h （x ）=恰有4个根，则满足＜＜2，解得：b ∈（，4），故选：D ．【点评】本题主要考查函数零点个数的判断，根据条件求出函数的解析式，利用数形结合是解决本题的关键．11．【答案】A【解析】解：∵z （1+i ）=2，∴z===1﹣i ．故选：A ．【点评】本题考查了复数的运算法则、共轭复数的定义，属于基础题．12．【答案】B【解析】解：∵α，β为锐角△ABC 的两个内角，可得α+β＞90°，cos β=sin （90°﹣β）＜sin α，同理cos α＜sin β，∴f （x ）=（）|x ﹣2|+（）|x ﹣2|，在（2，+∞）上单调递减，在（﹣∞，2）单调递增，由关于x的不等式f（2x﹣1）﹣f（x+1）＞0得到关于x的不等式f（2x﹣1）＞f（x+1），∴|2x﹣1﹣2|＜|x+1﹣2|即|2x﹣3|＜|x﹣1|，化简为3x2﹣1x+8＜0，解得x∈（，2）；故选：B．二、填空题13．【答案】②③．【解析】解：①根据双曲线的定义可知，满足|PA|﹣|PB|=2的动点P不一定是双曲线，这与AB的距离有关系，所以①错误．②由|PA|=10﹣|PB|，得|PA|+|PB|=10＞|AB|，所以动点P的轨迹为以A，B为焦点的图象，且2a=10，2c=6，所以a=5，c=3，根据椭圆的性质可知，|PA|的最大值为a+c=5+3=8，所以②正确．③方程2x2﹣5x+2=0的两个根为x=2或x=，所以方程2x2﹣5x+2=0的两根可分别作椭圆和双曲线的离心率，所以③正确．④由双曲线的方程可知，双曲线的焦点在x轴上，而椭圆的焦点在y轴上，所以它们的焦点不可能相同，所以④错误．故正确的命题为②③．故答案为：②③．【点评】本题主要考查圆锥曲线的定义和性质，要求熟练掌握圆锥曲线的定义，方程和性质．14．【答案】{1，6，10，12}．【解析】解：要使f A（x）f B（x）=﹣1，必有x∈{x|x∈A且x∉B}∪{x|x∈B且x∉A}={6，10}∪{1，12}={1，6，10，12，}，所以A△B={1，6，10，12}．故答案为{1，6，10，12}．【点评】本题是新定义题，考查了交、并、补集的混合运算，解答的关键是对新定义的理解，是基础题．15．【答案】3．【解析】解：直线l的方程为ρcosθ=5，化为x=5．点（4，）化为． ∴点到直线l

It's (40)_____ truly humbling (令人羞辱的) experience when an enormous whale comes alongside the boat and greets you like an old friend.Section B (10分)Directions: Complete the passage with the words in the box. Each word can only be used once. Note that there is one word more than you need.Junk food is everywhere. We’re eating way too much of it. Most of us know what we’re doing and yet we do it anyway.So here’s a suggestion (41)______ by two researchers at the Rand Corporation: Why not take a lesson from alcohol control policies and apply them to where food is sold and how it’s (42)______?“Many policy measures to control obesity （肥胖症）assume that people consciously and rationally choose what and how much they eat and therefore focus on providing information and more access to (43)______ foods,” note the two researchers.“In contrast,” the researchers continue, “many regulations that don’t assume people make rational choices have been successfully applied to control alcohol, a substance -- like food -- of which immoderate (44)______ leads to serious health problems.”The research references studies of people’s behavior with food and alcohol and results of alcohol restrictions, and then lists five regulations that the researchers think might be promising if applied to junk foods. Among them: Density (45)_____: licenses to sell alcohol aren't handed out (46)_____ to all comers but are allotted （分配）based on the number of places in an area that already sell alcohol. These make alcohol less easy to get and reduce the number of psychological cues to drink.Similarly, the researchers say, being presented with junk food (47)_______ our desire to eat it. So why not limit the density of food outlets, (48)______ ones that sell food rich in empty calories? And why not limit sale of food in places that aren’t (49)______food stores?Display and sales restrictions: California has a rule prohibiting alcohol displays near the cash registers in gas stations, and in most places you can’t buy alcohol at drive-through facilities. At supermarkets, food companies pay to have their wares in places where they’re easily seen. One could remove junk food to the back of the store and ban them from the shelves at checkout lines. The other measures include restricting portion sizes, taxing and prohibiting (50)_____ price deals for junk foods, and placing warning labels on the products.III.

Each passage is followed by several questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Behind most of the bad things we do to our bodies as adults, eating more than we should is the idea we carry with us from childhood. On the one hand, we assume that we are indestructible. On the other, we think that any damage we impose on ourselves can be undone when we finally clean up our act.If the evidence for how wrong the first idea is isn't apparent when you stand naked in front of the mirror, just wait. But what if you eat right and drop all your bad habits? Is there still time to repair the damage?To a surprising degree, the answer is yes. Over the past five years, scientists have accumulated a wealth of data about what happens when aging people with bad habits decide to turn their lives around. The heartening conclusion: the body has an amazing ability to heal itself, provided the damage is not too great.The effects of some bad habits--smoking, in particular--can haunt you for decades. But the damage from other habits can be largely healed. “Any time you improve your behavior and make lifestyle changes, they make a difference from that point on”, says Dr. Jeffrey Koplan. “Maybe not right away. It's like slamming on the brakes. You do need a certain distance”.But the distance can be remarkably short. Consider the recent announcements from the front lines of medical research:--A study concluded that women who consume as little as two servings of fish a week cut their risk of suffering a stroke to half that of women who eat less than one serving of fish a month.--The day you quit smoking, the carbon monoxide levels in your body drop dramatically. Within weeks, your blood becomes less sticky and your risk of dying from a heart attack starts to decline。
