  二、完形填空(共20小題;每小题1分,满分20分)
  Everyone who has faced disappointment or loss knows that it's not always easy to accept what life brings. From early childhood we experience situations in life that seem 1 or that don't make sense to us, from an unequal distribution of toys to all manner of bad things happening to 2 people. When we find ourselves faced with the 3 of life's apparent unfairness, it's often hard to let go and accept things as they are.
  The 4 part of non-acceptance of others, of those aspects of ourselves that we don't part non-acceptance of others, of those aspects of ourselves that we don't 5 or of situations we face in life that seem greatly unfair is that we stay stuck, and we stay stressed. Paradoxically (很矛盾地), 6 to accept those things in life that are unacceptable is often the most 7 step in releasing ourselves from our negative emotions.
  8 accepting those bad things in life is often easier said than done, it's much easier done when you know where to 9 , and you have a plan. Each of these 10 can help you to more easily practice acceptance. Used 11 , it becomes easier still.
  You can 12 yourself with some techniques. One of the most 13 ways is to actively focus on everything we have to appreciate. We now know that appreciation is a key component to happiness and inner 14 , so this is an important tool for acceptance and for overall life 15 . Often when we view things from a different perspective, we can 16 differently about them, and this 17 in feeling can make acceptance come much easier. That act of 18 things differently can help us to see the positive in what looks like the negative, and can help us to see the hidden 19 of a difficult situation. This act doesn't 20 the situation, but it can help us to see the situation differently, which can be transformative.   1. A. unfair B. unhelpful
  C. unnecessary D. unknown
  2. A. healthy B. good
  C. lucky D. rich
  3. A. complaint B. choice
  C. reality D. dilemma
  4. A. bare B. difficult
  C. lame D. blank
  5. A. like B. predict
  C. believe D. check
  6. A. continuing B. promising
  C. deserving D. learning
  7. A. optional B. important
  C. potential D. interesting
  8. A. Until B. Since
  C. While D. Once
  9. A. start B. rise
  C. appear D. belong
  10. A. duties B. versions
  C. facts D. tools
  11. A. again B. together

  三、閱读理解(共15小题;每小题2分,满分30分)
  A
  My father was 44 and knew he wasn't going to make it to 45. He wrote me a letter and hoped that something in it would help me for the rest of my life.
  Since the day I was 12 and first read his letter, some of his words have lived in my heart. One part always stands out. “Right now, you are pretending to be a time killer. But I know that one day, you will do something great that will set you among the very best.” Knowing that my dad believed in me gave me permission to believe in myself. “You will do something great.” He didn't know what would be, and neither did I, but at times in my life when I've felt proud of myself, I remember his words and wish he were here so I could ask, “Is this what you were talking about, Dad? Should I keep going?”
  A long way from 12 now, I realize he would have been proud when I made any progress. Lately, though, I've come to believe he would want me to move on to what comes next: to be proud of, and believe in, somebody else. It's time to start writing my own letters to my children. Our children look to us with the same unanswered question we had. Our kids don't hold back because they're afraid to fail. They're only afraid of failing us. They don't worry about being disappointed. Their fear—as mine was until my father's letter—is of being a disappointment.   Give your children permission to succeed. They're waiting for you to believe in them. I always knew my parents loved me. But trust me:That belief will be more complete, that love will be more real, and their belief in themselves will be greater if you write the words on their hearts: “Don't worry; you'll do something great.” Not having that blessing from their parents may be the only thing holding them back.
  1. We learn from the text that the author .
  A. lost his father when he was young
  B. worked hard before he read his father's letter
  C. asked his father's permission to believe in himself
  D. knew exactly what great thing his father wanted him to do
  2. What does the author tell us in the 3rd paragraph?
  A. Children need their parents' letters.
  B. Children are afraid to be disappointed.
  C. His children's fear of failure held them back.
  D. His father's letter removed his fear of failing his parents.
  3. The main purpose of the text is to .
  A. describe children's thinking
  B. answer some questions children have
  C. stress the importance of communication
  D. advise parents to encourage their children
  B
  Shopping is a game with two teams—shoppers and retails (零售商). Here is the game plan you need.
  Bargains and Impulse (沖动) Shopping
  Limit the number of stores you go to. The more “legwork” you put in, the more you may feel the need to “reward” yourself for your effort.
  Don't make friends with the sales staff. The more you interact (互动) with the sales staff, the more likely it is that you will buy something. This is because you feel like you don't want to let down someone who has helped you.
  Leave your credit cards at home. Research shows people are willing to spend more money with plastic than with cash. The less immediate the payment the more easily people will spend.
  At the Supermarket
  Slow down and double-check what you're picking up. Stores can make sales very specific and confusing, such as placing a sign offering 50% off a 2kg ham wedged (嵌入) between the full-price 3kg ones. Shoppers could wind up grabbing the wrong one and paying full price.
  Don't think when you buy in bulk (大批量) you're getting a better deal. That's not always the case. In the produce department, for example, individual capsicums are almost always cheaper than those in the multi-pack.
  Don't buy something in bulk just because it's on sale. The ten-for-$10 promotion is one of the most effective. This is what stores do to get volume out the door—even if they've raised the unit price to do it.   Shopping Online
  Hide your cookies. Companies use online cookies (a piece of data from a website stored on your web browser that informs the site of related net activity) to target shopper with relevant ads, but they can also reveal information from your browsing history. Stick to budget-friendly sites to bump into lower offers. And use your browser settings to block third-party tracking cookies.
  Look online first. Even if you choose to shop in store rather than online, check sites with user reviews and ratings, such as amazon.com and cnt.com, to find products with the most positive feedback. If the highest-rated items are cheaper online, including delivery, ask the store to match the total price.
  Geo-blocking is what some multinational retails do to charge different prices for the same product in different markets. With a little more effort, you can get around geo-blocking. Apple, for instance, will let you shop in their US store by using US iTunes gift-cards that can be bought online.
  Play the Game to Get Instant Bargains
  Speak up! Not happy with the view from your hotel window, or the way the burger is cooked? Don't be forced to put up with the poor experience, give honest, polite feedback and we're almost certain you'll be treated to what you expected—and paid for.
  Find better online actuation (驅动) deals. Misspelled it! One of the best ways to find great deals on eBay is via auctions (拍卖) that have misspelled words. For example, an “Xbox Connect” will often sell for less than an “Xbox Kinect” since fewer people search for the wrong version. Website FatFingers.com helps you find these listings. With thousands of items listed on eBay with spelling mistakes each year, you're likely to find what you're looking for at much lower prices.
  4. To control the impulse of shopping, the writer suggests that shoppers .
  A. follow their inner needs
  B. try to visit as many shops as possible
  C. pay in cash instead of by credit card
  D. have a close relationship with the sales staff
  5. When shopping online, shoppers can fight back against stores and advertisers by .
  A. blocking third-party tracking cookies
  B. thinking twice before buying in bulk
  C. buying products from other countries only
  D. avoiding being trapped by spelling mistakes
  6. The writer offers shoppers the game plan of shopping to .
  A. tell them how to get a perfect bargain   B. show them the ways to save shopping time
  C. warn them of the danger of the shopping game
  D. teach them how to communicate with retailers
  C
  Electronic sensors built into paper could be used in a range of ways from information storage to touch screens and more.
  Electronic sensors built into cartons (纸盒) may make it easier to tell when it's time to throw out rotten milk or orange juice. And that's just the start. At least that's the goal for researchers working on putting electronics into paper. They're trying to figure out how to combine the flexibility, low-cost and recyclability of paper with the information-carrying ability of electronics.
  Daniel Torbjork, a physics graduate student in Finland, has been working on the problem. He's published a review of the field in the journal Advanced Materials.
  Much research has been focused in this area. While most electronic applications require patterned conducting (传导的) structures, conductive paper could be used in applications such as energy storage devices sensors, electric heaters and others, according to Torbjork.
  “You could even have some interactive functions in magazines,” Torbjork said, “You could put a simple game in a package. If you want a touch screen, press a button and then something happen. Sensors in paper could tell us when something has gone bad.”
  Additional applications, such as information storage and security paper, have been suggested for magnetic papers containing magnetite. In Massachusetts, researchers have figured out how to post a video of such a device put into a paper airplane.
  German researchers have also put electronic chips in paper bank notes to defend counter-feiters (造偽币者). Paper is a good material but printing electronics also requires low-cost manufacturing. As many US and European paper makers lose market share to cheaper paper from China, these big paper companies are looking for added value products. That's where electronic paper devices could make a difference.
  “The major obstacles are paper's large surface roughness and chemical impurities.” Torbjork says. But others in the field think that electronic sensors in paper are still far from the consumer marketplace.
  “I don t think it' s going to happen.” said Roy Horgan.“You need a conductive surface. It could be 10 years out. What we are looking for are solutions that you can commercialize to-day.”
  Solar Print is partnering with Italian automaker Fiat to develop a unique auto-glass with tiny photostatic cells (光电) that can capture electricity from the sun. In the meantime, using paper to conduct electricity is still a “blue-sky” project.   “I would love to see someone prove me wrong, because that means that it's actually happening.” Horgan said.“If someone comes up with conductive paper, then that's a very interesting technology.”
  7. Putting electronics into paper will .
  A. cut the cost and impurity of paper
  B. depend on flexible conductive structure
  C. help consume rotten milk or orange juice
  D. combine the advantages of paper and electronics
  8. Paragraphs 4 to 7 mainly talk about the of the conductive paper.
  A. practical use B. theories
  C. structures D. design process
  9. Some paper makers welcome the new technology probably because it will .
  A. put an end to fake money
  B. make the paper smoother
  C. add more value to paper
  D. improve the printing technology
  10. From the passage,we know that Roy Horgan .
  A. has a burning desire to make a great profit
  B. showed much interest in Solar Print industry
  C. is not confident about the conductive paper
  D. started a “blue-sky” project to study paper
  D
  Lita CabEllut is one of Spain's most successful artists, but the woman whose paintings now sell for six figure sums spent her early years living on the street.
  “My childhood was like that of thousands of street kids around the world.” says Lita. She used to wander the streets and slept in the open air. Lita was born in a village in Aragon, north-east Spain, in 1961. While she was a baby, Lita was left with her grandmother—but in reality she spent most of her time out on the streets.
  “I ran after the walkers. They gave me money to buy packs of cigarettes or sandwiches, and I kept the change.” Looking back, she says. “Art, of course, was there because art is always around us.” But she was occupied with survival then.
  According to the 2014-2015 annual report,now her vivid portraits can sell for $100,000 or more—actors Hugh Jackman and Halle Berry, as well as chef, Gordon Ramsay, are each reported to own one, such as The Coco numero 4, Alam and Eddy Wenting and about 200 painting, drawings and more. Among the works and masters on exhibition the visitors will find the best pieces, most importantly Eddy Wenting.
  So what changed the course of Lita's life so dramatically? Lita's grandmother died when she was about 10 years old and she ended up in a Barcelona orphanage (孤兒院) before being adopted by “a beautiful Catalan family” two years later. She won't reveal much about them, except that they introduced her to art. They took her to Madrid's Prado museum,and introduce 13-year-old Lita to A Pilgrimage to San Isidro, which was painted between 1820 and 1823. “I recognized Goya's painting the expressions in the eyes of the people that I crossed in the streets when I was little,” she says.   “This painting describes the hope, the terrific moments that the human being can have when you lose your security. For me, when I saw this painting for the first time I felt the complicity (关联) of being a witness.”
  It made such an impression on her that she tried to copy another Goya, one of his sweeter works describing a country boy with a girl and a dog. The result was not spectacular but her adopted family encouraged little Lita to keep painting—they even paid for private tutors to make up for lost time.
  And for the first time in her life, she also started going to school. “It's difficult for me at school as I was so far behind. It's hard to start learning to read and write when you are 13, and then there's the psychological difficulty of being put into a class where classmates are much younger. I had a lot of private classes to learn everything.”
  She slowly made progress,started to listen to the “voice of art” and decided to study art at Amsterdam's Academy.
  The “three big masters” who influenced her the most were Spain's painter Goya, the sculptor Donatello, and German composer Bach. After graduating for many years, she stayed in the Netherlands and managed to establish a studio and now she has one in the Hague, but success didn't come easily.
  “I did things like giving someone a painting so they would pay my electricity bill and painting a house to get three months' credit in a supermarket. When you are in a growth period as an artist you have to defend it amazingly because you need time to become a master. If you exchange that time for money, you don't get that lime back to develop yourself.”
  At one point,having established a good relationship with an honorable gallery, she decided to start all over again, and didn't sell anything for two years.
  “I had painted a shocking series on child but her colleagues said, ‘No, Lita, you can't do this. People don't want this. Paint more angels, those angels that sell so well.’ I said ‘No, and I lost my gallery.’”
  Although Lita has held solo exhibitions in London. Dubai and Seoul, she is little known in her mother land.Two shows in 2017 are aimed at remedying this: a retrospective (回顧展) at Barcelona,and an exhibition at A Coruna's art museum where her studio will be recreated.
  As for her birth mother, Cabellut says she has forgiven her for abandoning her. She recalls once visiting her when the painter was a student but found it impossible to tell her how she felt.   11. What can we know about Lita's childhood life?
  A. She was given birth to in the Netherlands.
  B. She was adopted by an orphanage in 1973.
  C. She lived an ordinary life with her mother.
  D. She lost her grandma at the age of twelve.
  12. According to the passage,we know the painting “A Pilgrimage to San Isidro” .
  A. was exhibited in London museum
  B. was collected by actor Hugh Jackman
  C. was a best-known painting of Donatello
  D. was one works of Spain's painter Goya
  13. The underlined word “spectacular” in Paragraph 7 is closet in meaning to “ ”.
  A. frightening B. apparent
  C. necessary D. extraordinary
  14. When Lita said “NO” to the gallery,she really .
  A. didn't want to paint against her will
  B. would hold solo exhibitions in London
  C. was eager to come back to hometown
  D. found another gallery to cooperate with
  15. What can be the best title for the passage?
  A. How an artist travelled many countries
  B. How an artist was adopted and brought up
  C. How a street child became a leading artist
  D. How the three masters impressed an artist
  四、任務型阅读(共10小题;每小题1分,满分10分)
  At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is least. Earlier we were infants and young children, and consequently more vulnerable; later, we shall undergo a progressive loss of our vigour and resistance which, though not felt at first, will finally become so sudden and quick that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigour with the passing of time is called aging. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and diseases we shall eventually die of old age, and that this happens at a rate which differs little from person to person, so that there are heavy odds in favour of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer—on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and strong we are.
  Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigour with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things ‘wear out’. Most animals we commonly observe do in fact age as we do if given the chance to live long enough; and mechanical systems like a wound watch or the sun, do in fact run out of energy in accordance with the second law of thermodynamics (whether the whole universe does so is a matter about which there may be disagreement or uncertainty at present). But these are not similar to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself, it does not consist of living parts, only of metal, which wears away by friction. We could, at one time, repair ourselves well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power; an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again.   五、书面表达(满分25分)
  During a period of global economic depression, financial disturbance and trade protectionism, a country would face a battle to solve these issues alone. There is no denying that in the current situation, competition between countries is emphasized more than cooperation in that neither country would like to lose out to the other countries.
  The Hangzhou G20 summit, in which heads of state and government and central bankers get together to exchange views with each other, aims to create an “open innovation” environment, which means to promote innovation not only within a single country, but by virtue of cooperation with other countries, to deal with common problems facing all of humanity.
  “China has already become a big player in the international arena (竞技场). However, China alone cannot wrestle with all the problems,” said Atsushi Sunami, vice president at the National Graduate Institute for Policy Studies. “Being the second largest economy in the world, China needs to join forces with other nations to solve these existing problems, in relation to the environment, education, energy, clean water and climate change.”

  五、One possible version:
  The Hangzhou G20 summit places much emphasis on global cooperation rather than competition. It seeks to cope with the current issues in various fields, which can't be resolved by a single country.
  It is apparent that cooperation is a necessity for success in such a competitive society. First and foremost, teamwork can help us achieve shared targets in a more efficient way. Furthermore, cooperation provides people with opportunities, learning to show respect for others. Those who lack such essential skills are certain to be wiped out of the team in modern society.
  The success our Chinese women's volleyball players achieved in the 2016 Rio Olympics is a striking example of the point. While we weren't on the winning side at first, we struggled as a team to the last minute of the match. Without team spirit, we wouldn't have won the championship. It is cooperation that really counts in addressing problems we face.

立体几何是中学数学教学的重点内容之一,也是历届高考命题的热点.求解立体几何问题时,常因概念不清晰,理解不透彻,盲目地套用性质定理等导致错解.  一、概念不清导致错解  例1 判断下列说法是否正确,并说明理由.  (1)一点和一条直线确定一个平面;  (2)经过同一点的两条直线确定一个平面;  (3)首尾顺次相接的四条线段在同一平面内.  错解:(1)正确.错因:忽视公理2中“不在一条直线上的三点”

一、知识点归纳  二、重难点解读  1.圆锥曲线的定义:圆锥曲线的定义是解决圆锥曲线问题的根本依据.可以判断动点的轨迹的形状,可以求距离或其他量.特别地,利用抛物线的定义还可以实现点点距和点线距之间的转化,从而把某些问题化繁为简.  2.圆锥曲线的标准方程:对于椭圆和双曲线来说,就是中心在原点且焦点在坐标轴上的曲线的方程;对于抛物线来说,就是顶点在原点,焦点在坐标轴上的抛物线的方程.圆锥曲线的标准

一、整体思想  对有些圆锥曲线问题,注意其整体结构特点,设法将问题整体变形转化,以达到避免一些不必要的运算,降低解题难度.  例1 已知F1(-c,0)、F2(c,0)是椭圆M:x2a2+y2b2=1(a>b>0)的左、右焦点,O为坐标原点,  圆F2是以F2为圆心,c为半径的圆.若点P(-1,32)在椭圆上,线段PF2的中点在y轴上.  (1)求椭圆M的方程;  (2)如图,过F2且斜率为正数的
