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.

The morning after the storm, though, was beautiful: blue skies, warm air and a calm, inviting sea touching the shore gently.My father realized it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. TAL#NBSP I'm so glad I did.On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape. After all, it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big humps（脊背）in the distance.On approaching them, we saw it was a mother whale with her baby. We couldn't believe it—there aren't any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.The little baby whale—actually as big as our boat—was obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools（漩涡）and waves. "She's trying to help her baby, but on the wrong side, "my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, some-times rising from the water right beside us to breathe—and to give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day, Nearly four decades later,I still look back fondly to that golden day at sea.(1) The author says "I'm so glad I did." （in Para. 2） because.A. he witnessed the whole process of fishingB. he enjoyed the beauty of the calm seaC. he experienced the rescue of the whalesD. he spent the weekend with his family(2) The harbour survived the storm owing to.A. the shape of the harbourB. the arms of the bayC. the still water in the channelD. the long coast line(3) The mother whale failed to help her baby because.A. she had stayed in the polluted water for too longB. the whirl pools she had made were not big enoughC. she had no other whales around to turn to for helpD. the waves pushed her baby in the wrong direction(4) What is the theme of the story?A. Saving lives brings people a sense of happinessB. Fishing provides excitement for childrenC. It's necessary to live in harmony with animalsD.

Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents' point of view, the only cause of their fight is their adolescents' complete unreasonableness. And of course, TAL#NBSP the teens see it in exactly the same way, except oppositely.Both feel trapped.In this article, I'll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen's hair, the cleanliness of the bedroom, the preferred style of clothing, the child's failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right, It doesn't matter what the topic is—politics. The laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong. for both wish to be considered an authority—someone who actually knows something — and therefore to command respect. Unfortunately, as long as long as parents and teens continue to assume that they know more than the other, they'll continue to fight these battles forever and never make any real progress.(1) Why does the author compare the parent-teen war to a border conflict?A. Both can continue for generations.B. Both are about where to draw the lineC. Neither has any clear winnerD. Neither can be put to an end(2) What does the underlined part in Paragraph 2 mean?A. The teens blame their parents for starting the conflict.B. The teens agree with their parents on the cause of the conflictC. The teens cause their parents of misleading themD. The teens tend to have a full understanding of their parents(3) Parents and teens want to be right because they want to.A. give orders to the otherB. know more than the otherC. gain respect from the otherD. get the other to behave properly(4) What will the author most probably discuss in the paragraph that follows?A. Causes for the parent –teen conflictsB. Examples of the parent –teen war.C. Solutions for the parent –teen problemsD.

Yet these are girls in their teens or twenties but women in their sixties and seventies. A generation which would once only wear old-fashioned clothes is now favoring the same high street looks worn by those half their age.Professor Julia Twigg, a social policy expert, said, "Women over 75 are now shopping for clothes more frequently than they did when they were young in the 1960s. In the 1960s buying a coat for a woman was a serious matter. It was an expensive item that they would purchase only every three or four years —now you can pick one up at the supermarket whenever you wish to. Fashion is a lot cheaper and people get tired of things more quickly. "Professor Twigg analyzed family expending（支出）data and found that while the percentage of spending on clothes and shoes by women had stayed around the same—and 5 or 6 per cent of spending—the amount of clothes bought had risen sharply.The professor said, "Clothes are now 70 per cent cheaper than they were in the 1960s because of the huge expansion of production in the Far East. In the 1960s Leeds was the heart of the British fashion industry and that was where most of the clothes came from, but now almost all of our clothes are sourced elsewhere. Everyone is buying more clothes but in general we are not spending more money on them. "Fashion designer Angela Barnard, who runs her own fashion business in London, said older women were much more affected by celebrity（名流） style than in previous years.She said, "When people see stars such as Judi Dench and Helen Mirren looking attractive and fashionable in their sixties, they want to follow them. Older women are much more aware of celebrities. There's also the boom in TV programmes showing people how they can change their look, and many of my older customers do yoga to stay in shape well in their fifties. When I started my business a few years ago, my older customers tended to be very rich, but now they are what I would call ordinary women. My own mother is 61 and she wears the latest fashions in a way she would never have done ten years ago. "(1) Professor Twigg found that, compared with the 1960s,.A. the price of clothes has generally fallen by 70%B. the spending on clothes has increased by 5% or 6%C. people spend 30% less than they did on clothesD. the amount of clothes bought has risen by 5% or 6%(2) What can we learn about old women in terms of fashionA.

The author, W. H. Armstrong, starts with the basics: reading and writing. In his opinion, reading doesn't just mean recognizing each word on the page; it means taking in the information, digesting it and incorporating it into oneself just as one digests a sandwich and makes it a part of him. The goal is to bring the information back to life, not just to treat it as dead facts on paper from dead trees. Reading and writing cannot be completely separated from each other; in fact, the aim of reading is to express the information you have got from the text. I've seen it again and again：some-one who can't express an idea after reading a text is just as ineffective as someone who hasn't read it at all.Only a third of the book remains after that discussion, which Armstrong devotes to specific tips for studying languages, math, science and history. He generally handles these topics thoroughly（透彻地）and equally, except for some weakness in the science and math sections and a bit too much passion（激情） regarding history to his students, that was a hundred times more than my history teachers ever got across. To my disappointment, in this part of the book he ignores the arts. As a matter of fact, they demand all the concentration and study that math and science do, though the study differs slightly in kind. Although it's commonly believed that the arts can only be naturally acquired, actually, learning the arts is no more natural than learning French or mathematics.My other comment is that the text aged.The first edition apparently dates to the 1960s—none of the references（参考文献）seem newer than the late 1950s. As a result, the discussion misses the entire computer age.These are small points, though, and don't affect the main discussion. I recommend it to any student and any teacher, including the self-taught student.(1) According to Armstrong, the goal of reading is to.A. gain knowledge and expand one's viewB. understand the meaning between the linesC. experts ideas based on what one has readD. gets information and keeps it alive in memory(2) The author of the passage insists that learning the arts.A. requires great effortsB. demands real passionC. is less natural than learning mathsD. is as natural as learning a language(3) What is a shortcoming of Armstrong's work according to the author?A. Some ideas are slightly contradictory.B. There is too much discussion on studying science.C. The style is too serious.D. It lacks new information.(4) This passage can be classified as.A. an advertisementB. a book reviewC. a feature storyD. a news report16、【来源】 2010年高考真题湖北卷E篇第67~70题8分(每题2分)2010年高考真题湖北卷第16题EHave you winterized your horse yet? Even though global warming may have made our climate more mild, many animals are still hibernating(冬眠). It’s too bad that humans can’t hibernate. In fact,as a species, we almost did.Apparently, at times in the past, peasants in France liked a semi-state of human hibernation. So writes Graham Robb, a British scholar who has studied the sleeping habits of the French peasants. As soon as the weather turned cold people all over France shut themselves away and practiced the forgotten art of doing nothing at all for months on end.In line with this, Jeff Warren, a producerat CBC Radio’s The Current, tells us that the way we sleep has changed fundamentally since the invention of artificial(人造的) lighting and the electric bulb.When historians began studying texts of the Middle Ages, they noticed something referred to as “first sleep”, which was not clarified, though. Now scientists are telling us our ancestors most likely slept in separate periods. The business of eight hours’ uninterrupted sleep is a modern invention.In the past, without the artificial light of the city to bathe in, humans went to sleep when it became dark and then woke themselves around midnight. The late night period was known as “The Watch”It was when people actually kept watch against wild animals, although many of them simply moved around or visited family and neighbours.According to some sleep researchers,a short period of insomnia(失眠) at midnight is not a disorder. It is normal. Humans can experience another state of consciousness around their sleeping, which occurs in the brief period before we fall asleep or wake ourselves in the morning. This period can be an extraordinarily creative time for some people. The impressive inventor,Thomas Edison, used this state to hit upon many of his new ideas.Playing with your sleep rhythms can be adventurous, as anxiety may set in. Medical science doesn’t help much in this case. It offers us medicines for a full night’s continuous sleep, which sounds natural;however, according to Warren’s theory，it is really the opposite of what we need.(1) The example of the French peasants shows the fact that________.A. people might become lazy as a result of too much sleepB. there were signs of hibernation inhuman sleeping habitsC. people tended to sleep more peacefully in cold weatherD. winter was a season for people to sleep for months on end(2) The late night was called “The Watch” because it was a time for people______.A. to set traps to catch animalsB. to wake up their family and neighboursC. to remind others of the timeD. to guard against possible dangers(3) What does the author advise people to do?A. Sleep in the way animals do.B. Consult a doctor if they can’t sleep.C. Follow their natural sleep rhythm.D. Keep to the eight-hour sleep pattern.(4) What is the author’s purpose in writing the passage?A. To give a prescription for insomnia.B. To urge people to sleep less.C. To analyze the sleep pattern of modern people.D. To throw new light on human sleep.四、完成句子17、【来源】 2010年高考真题湖北卷第17题阅读下列各小题，根据括号内的汉语提示，用句末括号内的英语单词完成句子，并将答案写在答题卡上的相应题号后。
