He first came to the public’s attention at the Beijing Olympics in 2008, where he won three gold medals. During that race, he reached a top speed of 43.9 kmph. So, we ask, how does the man (21)_____ nickname is “Lightning Bolt” run so fast?Usain Bolt was born in Jamaica on 21 August 1986. He was running around at primary school, when a teacher noticed (22)_____ talent for sprinting (短跑). He became one of the best sprinters at his high school even though he didn’t train very hard.

He turned professional when he left high school, (24)_____ (age) seventeen. During the first couple of years of Bolt’s professional life, he got a few injuries, but his health soon improved and he began to win all the major championships. He went from strength to strength, (25)_____ (amaze) the world with his speed.So, how does he do it? Bolt says that he is naturally fast—just something he was born (26)_____. He’s also got a number of people looking after him and one of the main reasons for his success is Norman Peart, his manager. Peart (27)_____ (look) after Bolt since he was fifteen, working hard to keep him focused.(28)_____ you explain it, Bolt’s performances in Beijing were truly marvellous. What’s more marvellous is (29)_____, since then, he has continued to get even faster. In August 2009, he broke his own record by running the 100 metres in 9.58 seconds.

Take, for example, the disagreement about his 31 . The Spanish say he was from Spain, and the Italians claim he was from Italy. There is, in fact, some 32 that he was born in 1451 in Genoa, which is now part of Italy.Columbus became a sailor at an early age and had made journeys as far as Iceland and Guinea before he made his famous voyage in 1482. Contrary to popular 33 , Columbus didn’t sail to the Americas in order to find out whether the Earth was round: at the end of the 15th century almost everyone knew it was round. We do know that he sailed in part to fulfill a religious quest: he saw his journeys as a fulfillment of a divine (神圣的) plan for his life.Of course, the other 34 known reason for this voyage was that Columbus was looking for a new route to the Spice Islands (now part of Indonesia), and he believed he could reach them by sailing west rather than east. The discovery of the New World was therefore a(n) 35 case of “serendipity(机缘凑巧)”. In 1492, when he unexpectedly discovered the Americas, he had been traveling for five weeks and had sailed for 3,000 miles. He thought he had arrived in the East Indies.Columbus left on the voyage of discovery from the south of Spain, with a(n) 36 made up mainly of experienced sailors from the area. He made two 37 voyages before the end of the century, taking Europeans across to the new lands. On his third voyage in 1498, he also took women to the New World.This third voyage was not a happy one for Columbus. The settlers 38 against him, and he was unable to send a lot of gold back, so he was arrested and returned to Spain in chains.However, the King and Queen soon apologized, saying there had been a mistake, and Columbus was freed. By this time, 1500, Columbus was not a well man and he die d quietly at the age of 55 in Valladolid, Spain, on May 20, 1506, in his own apartment 39 by family and friends. He was a(n) 40 rich man at the time of his death.III. Reading ComprehensionSection ADirections:For each blank in the following passage there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.Agree to DisagreeIn a world of 6.5 million opinionated people, arguments are sure to happen. Many people see arguments as an inevitable and negative part of life. Inevitable, yes; 41 , maybe not. Arguments can often lead to positive change—if you argue 42 .Arguing “well”“There 43 is such a thing as a ‘healthy argument’,” says Marian Donahue, a human relations professional, San Diego. “In a healthy argument, one’s own goal should be to explain the i ssues in detail, to communicate the upset behind the issues, and to really seek to move forward toward a 44 ,” she says. “The minimum goal should be to preserve the relationship well enough to keep 45 alive.”What not to doNothing 46 a healthy argument like a personal attack, and personal attacks are a big no-no if you want an argument to end positively. Dina Connolly, a graduate student at Northwestern University, Illinois, says that when professional relationships start amassing (积累) personal baggage, 47 arguments are just aroundthe corner.“The structure or wall of professionalism collapses,” Connolly says, “taking down any filters as well. 48 , after an individual interrupted and then corrected me while making a public speech, I later ended up in an argument where I completely lost my temper and raised my voice. I was embarrassed, and because my relationship with that person was already so deconstructed and unprofessional, I 49 with that person directly and unprofessionally in a n unfiltered attack.”Don’t be 50 the heatDonahue 51 that personal issues must be left at the door—but that doesn’t mean arguments won’t get heated. “Passion and conflict are 52 in an argument as long as you keep to the issue,” she says. “At tacking the other person is not useful. That kind of argument closes downthe 53 on both sides to keep talking.”By actively listening, many arguments can be 54 altogether. If you do find yourself in the thick of one, listening with an open mind can bring about a swift 55 to the argument and perhaps a positive resolution.41. A. sure B. argumentative C. negative D. changing42. A. confidently B. correctly C. heatedly D. hesitantly43. A. definitely B. barely C. accidentally D. clearly44.

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)Things changed for Ben Southall when the Australian state of Queensland advertised a job for someone to look after Hamilton Island in the Great Barrier Reef. They knew it sounded like the best job in the world, but they were surprised when over 35,000 people applied for the job. Then they hadto make a difficult decision—which person to choose from so many candidates? After a lot of testing and interviewing, they announced 34-year-old Ben Southall from England as the winner. Ben now works for the Queensland Tourist Board and his job is to look after the island and to promote tourism there. Because of the unique nature of the job, the Tourist Board wanted a unique person, with a range of skills and qualities. It was a long interview process, involving a variety of tasks to find out about each candidate.Fitness was very important; swimming ability was particularly essential. Ben can swim very well and he also likes running,climbing, diving and mountain biking. It is clear that, physically, he can do almost anything. The ability to communicate was as important as fitness. For the last part of the interview process, the final sixteen andidates did various tests and tasks, including talking to TV and radio reporters.

（18分）穿过云朵直至阳光处——在第三次汉学家文学翻译国际研讨会上的发言贾平凹各位女士，各位先生：①几年前，我听到这样一句话：翻译就是世界文学。
这话让我吃惊，可冷静一想，事情确实是这样的，没有翻译，从何谈世界文学呢？正是一批中国作家的作品被翻译出去，尤其是被翻译出去的莫言先生获得了诺贝尔文学奖后，使世界才了解了和正在了解着中国文学。
翻译的功德巨大啊！现在，中国的政府、中国的文学组织机构，中国作家对翻译的热情很高，这次大会的主题是“解读．．中国故事”，其希望和目的要让中国作家的作品更多地翻译出去，翻译得更好更准确更丰满，有幸参加这个大会，对于如何解读中国故事的话题上，我谈谈我的一些认识。
②解读中国故事，就是让人知道这是中国的故事，并从故事中能读到当今中国是什么样子，中国人的生存状态和精神状态，能读出中国的气派、味道和意义。
而当下的中国，作家是极其多，作品也是极其多，据有关资料报道，仅长篇小说，每年就印刷出版三千余部，在这些庞大的作家群和作品堆里，怎么去识别哪些是有价值的作品，哪些是意义不大的作品，哪些作品值得被翻译出去，哪些作品是需要下工夫做的重点翻译？别说翻译家，就是中国的文学专业人员也难以做到那么好。
虽然对于一部作品的优劣高低鉴别那是自有一种标准和感觉的，好的就是好，不好就是不好，它会口口相传，产生出影响，但是当不可能把所有作品都读过，或无法从整体上来把握时，具体到某一部作品，常常是各人有各人的解读。
③我的意思是能多读些作品尽量去多读些作品，从而能从中国文学的整体上去把握和掌控，当把豆子平放在一个大盘里，好的豆子．．．．和不好的豆子就自然都发现了。
要了解孔子，不仅是读孔子，还有必要读老子，读荀子，读韩非子等等，这样更能了解孔子。
在这种能整体把握当下中国文学的基础上，就可以求辩解：中国之所以是中国，它的文学与西方文学有什么不同？与东方别的国家的文学有什么不同？它传达了当今中国什么样的生活？传达了当今中国什么样的精神和气质？这些生活这些精神这些气质，在世界文学的格局里呈现了什么样的意义？④这样，就可能遴选出一大批作品来，这些作品因作家的经历和个性不同，思想和审美不同，他们的故事和叙述方式就必然在形态上，色彩上，声响上，味道上各异。

辽宁省葫芦岛市普通协作体2017届高三12月月考
辽宁省葫芦岛市普通协作体2017届高三12月月考英语试卷及答案第Ⅰ卷第二部分阅读理解（共两节,满分40分）第一节（共15小题;每小题2分,满分30分）阅读下列短文, 从每题所给的四个选项（A、B、C和D）中, 选出最佳选项, 并在答题卡上将该项涂黑.AJoey is loyal, encouraging and self-sacrificing, always putting others’ interests ahead of his own. He is a hard worker, who also loves to run and play. In short, he’s an ideal friend and a heroic character.Here is the thing: Joey is a horse, who appears as the main character in Steven Spielberg’s new film War Horse.It is based on Michael Morpurgo’s 1982 novel, which also caused the same-titled Tony Awards winning play.The film follows the saga of Joey, a racehorse that’s trained for farm work under t he loving care of Albert (Jeremy Irvine)after Albert’s drunk father Ted(Peter Mullan) overpays for the animal at auction (拍卖会).Then the World War I tears Albert and Joey apart. Joey is sold into the war effort for the British and starts his episodic adventures in Europe.Splendidly staged, the battle plots in the film are visually astounding and impressive.And with Spielberg’s unique, top-notch direction and storytelling skills, War Horse cannot escape its episodic nature, calling to mind another Spielberg film about the horrors of war and its effects upon soldiers and civilians—Saving Private Ryan.While that film shocked us with horrific scenes of bleeding, it relied on a company of easily-described characters and a focused storyline to present heroic themes.Like Saving Private Ryan, War Horse clings to a series of characters, not only Albert, but also British officers, French civilians and German soldiers, who display courage in the face of danger. Everyone who comes in contact with Joey is either already in touch with their inner angel or is quickly moved to become more humane.Although none of this covers the fact that w e’ve seen this stuff elsewhere before, the lovely sentiment will steal your heart.And the emotional signature of Spielberg can be felt as he establishes the relationship between the boy and the horse and the mood of the piece—there will be tears.Theref ore, calling this beautiful, dramatically incomplete film “Saving Private Joey”, is entirely justifiable. 21．In common with “Saving Private Ryan”, the film War Horse _________.A．is full of terrifying scenes of bleeding and killingB．received the title of Tony Awards Winning PlayC．tells the story happening in the Second World WarD．covers a lot of characters22．Which statement is true according to the passage? _________.A．War Horse is based on the same-titled novel by Steven Spielberg.B．Joey is a heroic character because he saved many people’s lives.C．Joey came to Albert’s care after Ted paid a lot of money for it.D．Albert sold Joey into the war effort for Europe.23．According to the passage, what does the underlined word astounding mean? _________.A．confusingB．astonishingC．inspiringD．disappointing24．What is the best title for the passage? _________.A．Joey—a heroic race horseB．Albert and JoeyC．Spielberg’s JoeyD．Saving Private JoeyBLast July, we asked what you dream of doing as an adult. Thanks for your great responses! We wish we had room to print them all. Here are just a few.Work and playMy ideal job is being a construction worker, but only on an amusement park.James Martian, Age 9 AlaskaRoyal Fashion DesignerIn the future, I want to sew dresses for a queen. I could make whatever design I wanted. Her breakfast dress would be blue and long. Her lunch dress is purple and medium. Her dinner dress is red and short. They would all have sparkles. I think they would be pretty. I like my dream job.Jenna Suchyta, Age 6 WashingtonA “Police Law Fireman”When I grow up, I want to be a policeman or a fireman or a lawyer because they help people. Maybe I will combine all three and become a “Police Law Fireman”. I can work as a policeman in the morning. I can do law things in the afternoon. I can do fireman things in the evening. But for now, I want to be a boxer to build up my muscles. I will need my strength!Avi Samuels, Age 7 IllinoisPlaying in the BandMy dream job is to become a professional guitarist and singer for my future five-member rock band. I practice the guitar, and I have written hundreds of songs! The reason why I want to be a guitarist and singer is that I am veryinterested in music itself, so I want to create some of my own.Jake Francis, Age 12 Ohio25．What do you think is the best title for the passage? ________A．Your dream job.B．Your dream.C．Your future job.D．Your great chance.26．Who has done something for his or her future? ________A．James MartianB．Avi SamuelsC．Jake FrancisD．Jenna Suchyta27．Where can you find this passage? ________A．In a fashion magazine.B．In a children’s magazine.C．In an entertainment newspaper.D．On a website.CJust saw the superhero movie, Kick-Ass, and it raised an interesting question: just because we are not superhuman, can we lead a super-heroic life? I believe we can do it in some easy steps!Activate(刺激) our super powers.Superheroes are all good at different things. Some are really fast, some can see things others can’t, and some can move things with their mind. Also we all have special talents and passions. We just have to know what they are and develop them.Try this. List several things you’re especially good at—we’ll say these are your core super powers. Next, write down what makes each of your core super powers and look for chances to use them and improve them.Get a sidekick or two.Superheroes are out there all day, fighting the good fight. And who’s there to help? Every superhero has teamed up with someone else to defeat some enemies they couldn’t deal with alone.We need a support team: one or more who can be trusted and will help us when necessary. Our team members should bring different, constructive perspectives(观点) and all kinds of super powers. But we must choose wisely.Be brave and bold.Does it take more courage to venture(冒险) down a dark road or to face a life of no ventures at all? Both can be pretty scary. But we should be brave and bold just as some successful person said: “Have the courage to follow your heart and intuition(直觉). ”Live the code.Superheroes die to protect others. They don’t cheat or lie or steal. They’re good role models, and they do the right things even when nobody is watching.Though nobody’s perfect, yet we should learn from superheroes and struggle not to disobey the superhero code. Turn a friend down who trusts me? Of course I won’t.28．One of the similarities between superheroes and human beings is that both of them________.A．are very clever and passionateB．have their strong pointsC．try to remove their own weak pointsD．know how to be clever and bold29．The underlined word “siedkick” in the passage refers to a person who________.A．tries to watch you all the timeB．is much cleverer than youC．has super powers to support youD．is ready to help you anytime30．What is the superhero code? ________.A．Don’t be a bad person.B．Be willing to lose everything for others.C．Try to be a perfect person.D．Satisfy the needs of the friend you trust.31．What is the passage mostly about? ________.A．How we can become a superhero.B．What a superhero should be like.C．How we can live like a superhero.D．Why we should learn from a superhero.DI have two kids, a boy and a girl. I don’t worry about my girl; I’m sure she’ll be well trained in mixed martial arts. I worry about my son. I’m pretty sure he’s going to be feminine (女性化的). Sorry to say that, but let’s face it. No dad wants his son to go feminine.At the rate we’re moving in a couple of years you won’t be able to tell the difference between boys and girls. Sound extreme? Think about this. In every movie where advanced time-traveling beings come to our planet, there’s one constant: You can’t tell the male aliens from the female aliens!But that’s the future. Kids today are soft and fat. People ask why. Is it junk food? No. Junk food has been around for fifty years. Is it video games? No. Video games have been around for thirty years. None of the kids playing them back in the day were terribly obese. We’re all scratching our heads trying to figure out what we’ve introduced to society to ruin our kids. But it’s not anything we’ve added that has ruined our kids. It’s stuff we’ve gotten rid of.Take the gym rope for example. Remember that thing that stretched from the floor to the ceiling in your gym class that you could never climb? Most of the kids couldn’t make it to the top. But that wasn’t the point; the point was you had to try while some middle-aged guy who couldn’t make it up a flight of stairs shouted at you. We should have put our son on that rope, and given him a head start. But we didn’t want to shame the boy, so we took it down.Taking down the rope would be a good idea if there were no ropes in life. But they’re everywhere. You just can’t see them. They’re in every goal unrealized and expectation not met. The point everyone missed about the rope is you weren’t sup posed to make it to the top. It was there to create a fire that burned in the oversize belly of every kid.32．What is the example of aliens used to show? ________A．Girls are growing like boys.B．Boys are going feminine.C．There are really time-traveling beings.D．Alien movies are popular with children.33．What causes kids today to be soft and fat? ________A．Junk food.B．Video games.C．Stuff introduced to society.D．Things removed from society.34．How does the author find teenagers today? ________A．They have too much dignity.B．They are overprotected.C．They are less independent.D．They are thought too highly of.35．What does the rope probably symbolize? ________A．Goals.B．Expectations.C．Competition.D．Assistance.第二节(共5小题;每小题2分, 满分10分)根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项. 选项中有两项为多余选项.Starting university can be a costly experience for most people.

阅读下边的文段，达成 2-3 题。
【甲】人们常说：熟习的地方没有景色。
莫非城市也因熟习而让自己漠然了！【乙】可能是吧，但也不尽然， 不然又如何解说抖动心里那根柔嫩相思之弦的， 却常是老家那些光景而非这个城市或那个城市的花天酒地呢？ 【丙】或许用“距离产生美”来解说更能让自己满意， 也更通情达理一点。
归根结底，可能还是因为人不行能有两个故土，正如人没有两次生命同样吧。
