(16分)文学社会学的“摆渡”罗时进①中国古代诗文,从先秦到唐宋是各样文体的萌发、成长、形成阶段;明清诗文自然也有成长,甚至出现显性的发展,但这类发展是与回溯、总结相伴的。
也正因为这样,诗文二体迄于唐宋,内部构造方面的问题好多,而至明清则外面关系问题更为突出。
固然,几乎所有称之为“外面关系”方面的问题在唐宋以致先唐时代都有,但显然不如明清时代那样全面集中、高度表现,这难免令人好奇。
而正如文学内部构造拥有有关性相同,外面关系问题之丛生常常表现为两种形态:一是链式的,一是树形的。
前者是问题套连着问题,后者是主要问题旁生出诸多问题。

It’s quick, easy, and not chea p, but cheaper than buying a car the old way.The company has been working on the concept for the past two years. Their 31 car vending machine was installed in Atlanta in 2013. But they’ve spent time improving the design, in order to take user experience to the next level. “Our new Vending Machine is a state-of-the-art, multi-story structure that delivers our customers’ cars by merely 32 a special coin,” said Carvana CEO Ernie Garcia.The machine consists of a five-story glass tower that can hold up to 20 cars at a time. The tower basically serves as a(n) 33 point for used cars that customers purchase through the website, enabling 34 pricing and eliminating delivery costs.Customers can access a long list of specifications, ratings, reviews, and lots of other details about the cars they’re interested in on the Carvana website. They even get35 tours that point out every scratch on the body of the car. Once the car is chosen and paid for, the company usually delivers the car to the customer for a seven-day trial period. This usually means the delivery costs are worked into the 36 of the vehicle.But with the Vending Machine, customers are able to go to pick up their cars straight away. It’s a win-win 37 that allows Carvana to cut down on staff and overhead ( 间接费用), and save customers about $2,000 as well. According to the company, it also makes for a great 38 experience –placing an oversized coin in a slot ( 硬币投币口) and watching their car roll down automatically.“Carvana’s 39 is to create a better way to buy a car, and this new Vending Machine will be a one-of-a-kind experience, 40 just how simple and easy we’ve made it to buy a car online,” Garcia said. He added the company plans to build more car vending machines in the future.高三英语共 14页第 3页III.Reading ComprehensionSection ADirections: For each blank in the following passage there are four words or phrases marked A, B, Cand D. Fill in each blank with the word or phrase that best fits the context.Stay out of the Sun to Look YoungForget drinking countless glasses of water or getting your beauty sleep. The secret of looking young is simply to stay out of the sun. A study of hundreds of women has revealed that those who avoided the sun’s rays looked up to 20 years younger than they a ctually are.However, other supposed rules for a youthful complexion ( 肤色), from drinking lots of water to sleeping well and exercising regularly, failed to 41 the hands of time. Only keeping out of the sun, and wearing sunscreen when this wasn’t possible, made a42 , the American Academy of Dermatology’s annual conference will hear today. The interesting43 comes from a study of 231 women of all ages who were quizzed about their lives, including whether they were sun-lovers. When researchers from Massachusetts General Hospital in the US – commissioned by skincare firm Olay –guessed how old the women were, they found those who 44 in the sun tended to have aged more slowly.A lucky four had so few wrinkles and 45 spots, and such a fresh complexion, that they appeared to be a full two decades younger than they really were.Researcher Dr Alexa Kimball, a professor of dermatology (皮肤医学), said the 46 advice that we drink lots of water to stay healthy is actually a myth ( 谬见), and the body is ‘pretty good’ at judging how much we need.Previous research by the British Nutrition Foundation reached a 47 conclusion. Experts there said: ‘Just dr inking water for the sake of drinking water really has no effect on improving the appearance of skin.’ It isn’t clear why the women who 48 well didn’t have younger-looking skin. But it may be that the question they were asked was too 49 and didn’t t ake into account their long-term sleep patterns.A second study, also by Olay, suggested that low-level day to day exposure to the sun is more ageing than 50 , intense exposure. Finally, DNA examination of tiny samples of the women’s skin helped understand the 51 done by the sun. A gene called CDKN2A was more active in facial skin that is exposed to the elements than in samples taken from the bottoms. This gene was also more active in women who said they loved the 52 –and in those who looked older. Dr Kimball said CDKN2A activity is a 53 that a cell is ‘tired out’ and urged women should protect their skin year round and not just when on a beach holiday.Dr Frauke Neuser, principal scientist at Olay, which has used the 54 to develop its latest face creams, said: ‘This research gives us a detailed picture of the effect of sun exposure on skin ageing and illustrate the importance of protection on a 55 basis.’41.

And they are examples of the evolution of animation, which has brought unique new life to the film industry.Among the first American animated films was Light of the Moon, a silent movie produced in 1911 using silhouette (剪影) animation, where the characters are represented only as black silhouettes.The real breakthrough for American animation came with Steamboat Willie, created by Walt Disney and released in 1928. It was the first animated film to be accompanied by sound, and its main star, Mickey Mouse, became one of the most loveable and enduring animated characters ever created. Disney also created the first American full-length animated film, Snow White and the Seven Dwarfs. Released in 1937, it enjoyed worldwide box-office success.Disney’s extremely careful attention to high-quality detail in the thousands of hand-painted drawings required at that time to make an animated film elevated this film technique to the level of a serious art form.Clay animation is a type of stop-motion animation using forms made of clay. Clay animation films have been produced in the United States since 1908. But this form of animation only won wide popular appeal in 1955 with a short film called Gumbasia, created by Art Clokey.Computer-generated imagery, or CGI, brought animation to a new level of artistry and realism. Used in film since the 1960s, CGI animation began to develop rapidly in the mid-1990s. Toy Story, released in 1995 and created by Pixar and Disney Studios, was the first completely computer-generated animated feature film.In 2001, DreamWorks and Pacific Data Images released Shrek, the first computer-animated feature film to win an Oscar. Shrek returned in 2004 with his talking donkey, his princess bride Fiona高三英语共 14页第 5页and an army of fairy-tale characters in Shrek 2. Hugely popular, that film became the highest-grossing (票房最高的) animated film of all time.In addition to strictly animated movies, animation has been mixed into films showing live actors as well. Who can forget the terrifyingly real dinosaurs thundering through Steven Spielberg’s Jurassic Park movies and the actors they chased? Thanks to the powerful capabilities of today’s computers and the unlimited imagination of American filmmakers, animation will be entertaining audiences worldwide for a long time to come.56.The passage is mainly about the of animation.A. influenceB. popularityC. charactersD. development57.Which film marked the beginning of the complete digital age of American a nimation?A.

The program, which lasted from first grade through tenth grade, reduced arrests and use of health and mental health services as the students aged through adolescence and young adulthood, as researchers explained in a separate study.In the latest study, researchers looked at the “why” behind those previous findings. In looking at the data from nearly 900 students, the researchers found that about a third of the impact on future crime outcomes was due to the social and self-regulation skills the students learned from ages 6 to 11.The academic skills that were taught as part of Fast Track turned out to have less of an impact on crime than did the soft skills, which are associated with emotional intelligence.“The conclusion that we would make is that these soft skills should be emphasized even more in our education system and in our system of socializing children,” says Kenneth Dodge, a p rofessor at Duke who was a principal investigator in this study as well as in the original Fast Track project. Parents should do all they can to promote these skills with their children, Dodge says, as should education policymakers.To Neil Bernstein, a psychologist in Washington, D.C., who specializes in child and adolescent behavior disorders, the researchers’ findings seem to match what he’s seen among the general public in working with children for more than 30 years. And while he says he agrees with the importance of teaching self-control and social skills, he would add empathy to the list, too.“Empathy is what makes us aware of the feelings of others, and when you’re empathic, you’re much less likely to hurt someone else’s feelings,” says Bernstein, w ho serves on the advisory board for the Partnership for Drug-Free Kids. “Being in tune with how someone else feels might also make adolescents avoid bullying and other behaviors of concern,” Bernstein says.While Bernstein thinks the study’s findings are m eaningful and could potentially serve as a model for schools, he says that collectively getting a school system, teachers, parents and students all motivated enough to take part in an intervention like Fast Track is challenging.63.Fast Track is aimed to .A. improve children’s academic skillsB. help the children with behavior disordersC. identify the problematic childrenD. classify children into different groups64.Neil Bernstein thinks that .A.empathic children are more likely to have higher emotional intelligenceB.the findings of the studies disagree with what he has found in his work高三英语共 14页第 8页C.empathy is equally essential in educating and socializing childrenD.self-control and social skills are not as important as empathy65.What can be learned from the passage?A.It’s hard to involve everyone concerned in applying the findings.B.Soft skills were not part of the education system in the past.C.The findings are meaningless unless guided by Fast Track.D.Adolescence is the most critica l stage in a person’s life.66.What does the passage mainly tell us?A.Academic skills are paid too much attention at schools.B.Academic skills have no influence on children’s behaviors.C.Soft skills are much harder to develop than academic skills.D.Soft skills play a significant role in preventing future crimes.Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.A.So it’s not easy for English speakers to label place values clearly.B.The additional mental steps needed to solve problems cause more errors.C.Differences between Chinese and English, in particular, have been studied for decades.D.This method is a powerful tool for solving more advanced multi-digit addition and subtractionproblems.E.Different languages indicate different ways of thinking, causing people to solve mathproblems differently.F.That makes it easier for children to understand the place value as well as making it clear thatthe number system is based on units of 10.The Best Language for MathWhat’s the best language for learning math? Hint: You’re not reading it.Chinese, Japanese and Korean use simpler number words and express math concepts more clearly than English. The language gap is drawing growing attention as confusing English number words have been linked in several studies to weaker counting and arithmetic skill in children in English-speaking countries.67 Among the researchers are Karen Fuson, a professor in the School of Education at Northwestern University, and Li Yeping, an expert on Chinese math education at Texas A&M University.Chinese has just nine number words, while English has more than two dozen. The trouble starts at “11”. English has a unique word for the number, while Chinese (as well as Japanese and Korean, among other languages) have words that can be translated as “ten-one” –spoken with the “ten” first.68English number words over 10 d on’t as clearly label place values. Number words for the teens高三英语共 14页第 9页reverse the order of the ones and “teens”, making it easy for children to confuse, say, 17 with 71. As a result, children working with English number words have a harder time doing multi-digit addition and subtraction ( 减法). 69It also feels more natural for Chinese speakers than for English speakers to use the “make-a-ten”addition and subtraction strategy. When adding two numbers, students break down the numbers into parts and regroup them into tens and ones. For instance, 9 plus 5 becomes 9 plus 1 plus 4. 70 Many teachers in America have increased instruction in the make-a-ten method and called for first-graders to use it to add and subtract.Now, you should feel lucky that you are learning math in China. Thanks to your mother tongue,all math problems just come less confusing and difficult to you!IV.Summary WritingDirections: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.From Burn Survivor to Global InspirationLast October, the Kona Ironman World Championship witnessed an unbelievable finish. Turia Pitt, an Australian woman who suffered severe burns when caught in a bush fire during a marathon six years ago, successfully challenged herself.Pitt spent 864 days in a hospital and went through more than 200 operations. Doctors said she would never run again, but she proved them wrong.Crossing the line in the Hawaiian darkness, Pitt showed incredible emotion as the race commentator ( 现场解说员) announced: “Turia Pitt, you are an ironman!” On social media, people around the world applauded her determination.Apart from continuing to be a star athlete, Pitt is also a motivational speaker now. She is sharing her journey of recovery with others to help raise awareness about the importance of organ donation, which she believes saved her life.Pitt was 24 years old when she and five others encountered the fire. Doctors had to remove the burnt skin and replace it with donated skin that could fight infection. None could be found in Australia and doctors were forced to search abroad. They finally found skin that could be used in the United States.“I’m not being dramatic, but it was the skin that saved my life,” said Pitt. “I decided to live my life to the best of my abilities because I never wanted those donors, wherever they are, to think I was ungrateful for their gi ft.”So Pitt set herself a big goal: the Kona Ironman World Championship. In order to compete, she had to first learn how to stand, walk and even talk all over again. And because of her burns, she also has trouble sweating and regulating her body temperature.Despite these disadvantages, Pitt completed the race in just 14 hours. She said this achievement would not be possible without the donated skin, highlighting the importance of organ donation.高三英语共 14页第 10页V.TranslationDirections: Translate the following sentences into English, using the words given in the brackets.72.你能感受到大数据给现代生活带来的冲击吗?(impact)73.我们在向西方学习的时候不能丢弃自己独特的文化特征。

It’s quick, easy, and not cheap, but cheaper than buying a car the old way.The company has been working on the concept for the past two years. Their 31 car vending machine was installed in Atlanta in 2013. But they’ve spent time improving the design, in order to take user experience to the next level. “Our new Vending Machine is a state-of-the-art, multi-story structure that delivers our customers’ cars by merely 32 a special coin,” said Carvana CEO Ernie Garcia.The machine consists of a five-story glass tower that can hold up to 20 cars at a time. The tower basically serves as a(n) 33 point for used cars that customers purchase through the website, enabling 34 pricing and eliminating delivery costs.Customers can access a long list of specifications, ratings, reviews, and lots of other details about the cars they’re interested in on the Carvana website. They even get 35 tours that point out every scratch on the body of the car. Once the car is chosen and paid for, the company usually delivers the car to the customer for a seven-day trial period. This usually means the delivery costs are worked into the 36 of the vehicle.But with the Vending Machine, customers are able to go to pick u p their cars straight away. It’s a win-win 37 that allows Carvana to cut down on staff and overhead(间接费用), and save customers about $2,000 as well. According to the company, it also makes for a great 38 experience –placing an oversized coin in a slot(硬币投币口) and watching their car roll down automatically.“Carvana’s 39 is to create a better way to buy a car, and this new Vending Machine will be a one-of-a-kind experience, 40 just how simple and easy we’ve made it to buy a car online,” Garcia said. He added the company plans to build more car vending machines in the future.高三英语共13页第3页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.Stay out of the Sun to Look YoungForget drinking countless glasses of water or getting your beauty sleep. The secret of looking young is simply to stay out of the sun. A study of hundreds of women has revealed that those who avoided the sun’s rays looked up to 20 years younger than they actually are.However, other supposed rules for a youthful complexion (肤色), from drinking lots of water to sleeping well and exercising regularly, failed to 41 the hands of time. Only keeping out of the sun, and wearing sunscreen when this wasn’t possible, made a 42 , the American Academy of Dermatology’s annual confer ence will hear today. The interesting 43 comes from a study of 231 women of all ages who were quizzed about their lives, including whether they were sun-lovers. When researchers from Massachusetts General Hospital in the US – commissioned by skincare firm Olay –guessed how old the women were, they found those who 44 in the sun tended to have aged more slowly. A lucky four had so few wrinkles and 45 spots, and such a fresh complexion, that they appeared to be a full two decades younger than they really were.Researcher Dr Alexa Kimball, a professor of dermatology(皮肤医学), said the 46 advice that we drink lots of water to stay healthy is actually a myth (谬见), and the body is ‘pretty good’ at judging how much we need.Previous research by the British Nutrition Foundation reached a 47 conclusion. Experts there said: ‘Just drinking water for the sake of drinking water really has no effect on improving the appearance of skin.’It isn’t clear why the women who 48 well didn’t have younger-looking skin. But it may be that the question they were asked was too 49 and didn’t take into account their long-term sleep patterns.A second study, also by Olay, suggested that low-level day to day exposure to the sun is more ageing than 50 , intense exposure. Finally, DNA examination of tiny samples of the women’s skin helped understand the 51 done by the sun. A gene called CDKN2A was more active in facial skin that is exposed to the elements than in samples taken from the bottoms. This gene was also more active in women who said they loved the 52 –and in those who looked older. Dr Kimball said CDKN2A activity is a 53 that a cell is ‘tired out’ and urged women should protect their skin year round and not just when on a beach holiday.Dr Frauke Neuser, principal scientist at Olay, which has used the 54 to develop its latest face creams, said: ‘This research gives us a detailed picture of the effect of sun exposure on skin ageing and illustrate the importance of protection on a 55 bas is.’41.

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)Mickey Mouse and Shrek are just a couple of the American animated (动画的) characters loved the world over. And they are examples of the evolution of animation, which has brought unique new life to the film industry.Among the first American animated films was Light of the Moon, a silent movie produced in 1911 using silhouette (剪影) animation, where the characters are represented only as black silhouettes.The real breakthrough for American animation came with Steamboat Willie, created by Walt Disney and released in 1928. It was the first animated film to be accompanied by sound, and its main star, Mickey Mouse, became one of the most loveable and enduring animated characters ever created. Disney also created the first American full-length animated film, Snow White and the Seven Dwarfs. Released in 1937, it enjoyed worldwide box-office success.Disney’s extremely careful attention to high-quality detail in the thousands of hand-painted drawings required at that time to make an animated film elevated this film technique to the level of a serious art form.Clay animation is a type of stop-motion animation using forms made of clay. Clay animation films have been produced in the United States since 1908. But this form of animation only won wide popular appeal in 1955 with a short film called Gumbasia, created by Art Clokey.Computer-generated imagery, or CGI, brought animation to a new level of artistry and realism. Used in film since the 1960s, CGI animation began to develop rapidly in the mid-1990s. Toy Story, released in 1995 and created by Pixar and Disney Studios, was the first completely computer-generated animated feature film.In 2001, DreamWorks and Pacific Data Images released Shrek, the first computer-animated feature film to win an Oscar. Shrek returned in 2004 with his talking donkey, his princess bride Fiona高三英语共13页第5页and an army of fairy-tale characters in Shrek 2. Hugely popular, that film became the highest-grossing (票房最高的) animated film of all time.In addition to strictly animated movies, animation has been mixed into films showing live actors as well. Who can forget the terrifyingly real dinosaurs thundering through Steven Spielberg’s Jurassic Park movies and the ac tors they chased? Thanks to the powerful capabilities of today’s computers and the unlimited imagination of American filmmakers, animation will be entertaining audiences worldwide for a long time to come.56.

The program, which lasted from first grade through tenth grade, reduced arrests and use of health and mental health services as the students aged through adolescence and young adulthood, as researchers explained in a separate study.In the latest study, researchers looked at the “why” behind those previous findings. In looking at the data from nearly 900 students, the researchers found that about a third of the impact on future crime outcomes was due to the social and self-regulation skills the students learned from ages 6 to 11.The academic skills that were taught as part of Fast Track turned out to have less of an impact on crime than did the soft skills, which are associated with emotional intelligence.“The conclusion that we would make is that these soft skills should be emphasized even more in our education system and in our system of socializing children,” says Kennet h Dodge, a professor at Duke who was a principal investigator in this study as well as in the original Fast Track project. Parents should do all they can to promote these skills with their children, Dodge says, as should education policymakers.To Neil Bernstein, a psychologist in Washington, D.C., who specializes in child and adolescent behavior disorders, the researchers’ findings seem to match what he’s seen among the general public in working with children for more than 30 years. And while he says he agrees with the importance of teaching self-control and social skills, he would add empathy to the list, too.“Empathy is what makes us aware of the feelings of others, and when you’re empathic, you’re much less likely to hurt someone else’s feelings,” says Bernstein, who serves on the advisory board for the Partnership for Drug-Free Kids. “Being in tune with how someone else feels might also make adolescents avoid bullying and other behaviors of concern,” Bernstein says.While Bernstein thinks the study’s fi ndings are meaningful and could potentially serve as a model for schools, he says that collectively getting a school system, teachers, parents and students all motivated enough to take part in an intervention like Fast Track is challenging.63. Fast Track is aimed to _____.A. improve children’s academic skillsB. help the children with behavior disordersC. identify the problematic childrenD. classify children into different groups64. Neil Bernstein thinks that _____.A. empathic children are more likely to have higher emotional intelligenceB. the findings of the studies disagree with what he has found in his work高三英语共13页第8页C. empathy is equally essential in educating and socializing childrenD. self-control and social skills are not as important as empathy65. What can be learned from the passage?A. It’s hard to involve everyone concerned in applying the findings.B. Soft skills were not part of the education system in the past.C. The findings are meaningless unless guided by Fast Track.D. Adolescence is the most critical stage in a person’s life.66. What does the passage mainly tell us?A. Academic skills are paid too much attention at schools.B. Academic skills have no influence on children’s behaviors.C. Soft skills are much harder to develop than academic skills.D. Soft skills play a significant role in preventing future crimes.Section CDirections: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.The Best Language for MathWhat’s the best language for learning math? Hint: You’re not reading it.Chinese, Japanese and Korean use simpler number words and express math concepts more clearly than English. The language gap is drawing growing attention as confusing English number words have been linked in several studies to weaker counting and arithmetic skill in children in English-speaking countries.67 Among the researchers are Karen Fuson, a professor in the School of Education at Northwestern University, and Li Yeping, an expert on Chinese math education at Texas A&M University.Chinese has just nine number words, while English has more than two dozen. The trouble starts at “11”. English has a unique word for the number, while Chinese (as well as Japanese and Korean, among other languages) have words that can be translated as “ten-one”– spoken with the “ten” first.68English number words over 10 don’t as clearly label place values. Number words for the teens高三英语共13页第9页reverse the order of the ones and “teens”, making it easy for children to confuse, say, 17 with 71. As a result, children working with English number words have a harder time doing multi-digit addition and subtraction (减法). 69It also feels more natural for Chinese speakers than for English speakers to use the “make-a-ten”addition and subtraction strategy. When adding two numbers, students break down the numbers into parts and regroup them into tens and ones. For instance, 9 plus 5 becomes 9 plus 1 plus 4. 70 Many teachers in America have increased instruction in the make-a-ten method and called for first-graders to use it to add and subtract.Now, you should feel lucky that you are learning math in China. Thanks to your mother tongue, all math problems just come less confusing and difficult to you!IV. Summary WritingDirections: Read the following passage.

Turia Pitt, an Australian woman who suffered severe burns when caught in a bush fire during a marathon six years ago, successfully challenged herself.Pitt spent 864 days in a hospital and went through more than 200 operations. Doctors said she would never run again, but she proved them wrong.Crossing the line in the Hawaiian darkness, Pitt showed incredible emotion as the race commentator (现场解说员) announced: “Turia Pitt, you are an ironman!”On social media, people around the world applauded her determination.Apart from continuing to be a star athlete, Pitt is also a motivational speaker now. She is sharing her journey of recovery with others to help raise awareness about the importance of organ donation, which she believes saved her life.Pitt was 24 years old when she and five others encountered the fire. Doctors had to remove the burnt skin and replace it with donated skin that could fight infection. None could be found in Australia and doctors were forced to search abroad. They finally found skin that could be used in the United States.“I’m not being dramatic, but it was the skin that saved my life,” said Pitt. “I decided to live my life to the best of my abilities because I never wanted those donors, wherever they are, to think I was ungrateful for their gift.”So Pitt set herself a big goal: the Kona Ironman World Championship. In order to compete, she had to first learn how to stand, walk and even talk all over again. And because of her burns, she also has trouble sweating and regulating her body temperature.Despite these disadvantages, Pitt completed the race in just 14 hours. She said this achievement would not be possible without the donated skin, highlighting the importance of organ donation.高三英语共13页第10页V.

It’s quick, easy, and not cheap, but cheaper than buying a car the old way.The company has been working on the concept for the past two years. Their 31 car vending machine was installed in Atlanta in 2013. But they’ve spent time improving the design, in order to take user experience to the next level. “Our new Vending Machine is a state-of-the-art, multi-story structure that delivers our customers’ cars by merely 32 a special coin,” said Carvana CEO Ernie Garcia.The machine consists of a five-story glass tower that can hold up to 20 cars at a time. The tower basically serves as a(n) 33 point for used cars that customers purchase through the website, enabling 34 pricing and eliminating delivery costs.Customers can access a long list of specifications, ratings, reviews, and lots of other details about the cars they’re int erested in on the Carvana website. They even get 35 tours that point out every scratch on the body of the car. Once the car is chosen and paid for, the company usually delivers the car to the customer for a seven-day trial period. This usually means the delivery costs are worked into the 36 of the vehicle.But with the Vending Machine, customers are able to go to pick up their cars straight away. It’s a win-win 37 that allows Carvana to cut down on staff and overhead (间接费用), and save customers about $2,000 as well. According to the company, it also makes for a great 38 experience – placing an oversized coin in a slot (硬币投币口) and watching their car roll down automatically.“Carvana’s 39 is to create a better way to buy a car, and this new Vending Machine will be a one-of-a-kind experience, 40 just how simple and easy we’ve made it to buy a car online,” Garcia said. He added the company plans to build more car vending machines in the future.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.Stay out of the Sun to Look YoungForget drinking countless glasses of water or getting your beauty sleep. The secret of looking young is simply to stay out of the sun. A study of hundreds of women has revealed that those who avoided the sun’s rays looked up to 20 years younger than they actually are.However, other supposed rules for a youthful complexion (肤色), from drinking lots of water to sleeping well and exercising regularly, failed to 41 the hands of time. Only keeping out of the sun, and wearing sunscreen when this wasn’t possible, made a 42 , the American Academy of Dermatolog y’s annual conference will hear today. The interesting 43 comes from a study of 231 women of all ages who were quizzed about their lives, including whether they were sun-lovers. When researchers from Massachusetts General Hospital in the US –commissioned by skincare firm Olay – guessed how old the women were, they found those who 44 in the sun tended to have aged more slowly. A lucky four had so few wrinkles and 45 spots, and such a fresh complexion, that they appeared to be a full two decades younger than they really were.Researcher Dr Alexa Kimball, a professor of dermatology (皮肤医学), said the 46 advice that we drink lots of water to stay healthy is actually a myth (谬见), and the body is ‘pretty good’ at judging how much we need.Previous research by the British Nutrition Foundation reached a 47 conclusion. Experts there said: ‘Just drinking water for the sake of drinking water really has no effect on improving the appearance of skin.’ It isn’t clear why the women who 48 well didn’t have younger-looking skin. But it may be that the question they were asked was too 49 and didn’t take into account their long-term sleep patterns.A second study, also by Olay, suggested that low-level day to day exposure to the sun is more ageing than50 , intense exposure. Finally, DNA examination of tiny samples of the women’s skin helped understand the51 done by the sun. A gene called CDKN2A was more active in facial skin that is exposed to the elements than in samples taken from the bottoms. This gene was also more active in women who said they loved the 52 –and in those who looked older. Dr Kimball said CDKN2A activity is a 53 that a cell is ‘tired out’ and urged women should protect their skin year round and not just when on a beach holiday.Dr Frauke Neuser, principal scientist at Olay, which has used the 54 to develop its latest face creams, said: ‘This research gives us a detailed picture of the effect of sun exposure on skin ageing and illustrate the importance of protection on a 55 basis.’41.

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)Mickey Mouse and Shrek are just a couple of the American animated (动画的) characters loved the world over. And they are examples of the evolution of animation, which has brought unique new life to the film industry.Among the first American animated films was Light of the Moon, a silent movie produced in 1911 using silhouette (剪影) animation, where the characters are represented only as black silhouettes.The real breakthrough for American animation came with Steamboat Willie, created by Walt Disney and released in 1928. It was the first animated film to be accompanied by sound, and its main star, Mickey Mouse, became one of the most loveable and enduring animated characters ever created. Disney also created the firstAmerican full-length animated film, Snow White and the Seven Dwarfs. Released in 1937, it enjoyed worldwide box-office success.Disney’s extremely careful attention to high-quality detail in the thousands of hand-painted drawings required at that time to make an animated film elevated this film technique to the level of a serious art form.Clay animation is a type of stop-motion animation using forms made of clay. Clay animation films have been produced in the United States since 1908. But this form of animation only won wide popular appeal in 1955 with a short film called Gumbasia, created by Art Clokey.Computer-generated imagery, or CGI, brought animation to a new level of artistry and realism. Used in film since the 1960s, CGI animation began to develop rapidly in the mid-1990s. Toy Story, released in 1995 and created by Pixar and Disney Studios, was the first completely computer-generated animated feature film.In 2001, DreamWorks and Pacific Data Images released Shrek, the first computer-animated feature film to win an Oscar. Shrek returned in 2004 with his talking donkey, his princess bride Fiona and an army of fairy-tale characters in Shrek 2. Hugely popular, that film became the highest-grossing (票房最高的) animated film of all time.In addition to strictly animated movies, animation has been mixed into films showing live actors as well. Who can forget the terrifyingly real dinosaurs thundering through Steven Spielberg’s Jurassic Park movies and the actors they chased? Thanks to the powerful capabilities of today’s computers and the unlimited imagination of American filmmakers, animation will be entertaining audiences worldwide for a long time to come.56. The passage is mainly about the _____ of animation.A. influenceB. popularityC. charactersD. development57. Which film marked the beginning of the complete digital age of American animation?A. Light of the Moon.B. Steamboat Willie.C. Toy Story.D. Shrek.58. It can be learned from the passage that _____.A. Disney played a very important role in promoting animationB. computers make animated characters more lovelyC. Jurassic Park movies involve only live actorsD. clay animation enjoys long-lasting popularity59. What can be inferred about the future of animation from the passage?A. Animation will forever remain an essential form of entertainment.B. Animation will be replaced by new forms of films in the near future.C. Animation will continuously gain new life due to computers and imagination.D. Animation will get more popular in the future for the developing film technology.(B)The Puffing Billy Railway, located about 40km east of Melbourne, was constructed in the early 1900s to open up remote areas.

In order to compete, she had to first learn how to stand, walk and even talk all over again. And because of her burns, she also has trouble sweating and regulating her body temperature.Despite these disadvantages, Pitt completed the race in just 14 hours. She said this achievement would not be possible without the donated skin, highlighting the importance of organ donation.________ ________ ________ ________ ________ ________ ________ ________ ________ ________________ ________ ________ ________ ________ ________ ________ ________ ________ ________________ ________ ________ ________ ________ ________ ________ ________ ________ ________________ ________ ________ ________ ________ ________ ________ ________ ________ ________________ ________ ________ ________ ________ ________ ________ ________ ________ ________________ ________ ________ ________ ________ ________ ________ ________ ________ ________。

(16分)文学社会学的“摆渡”罗时进①中国古代诗文,从先秦到唐宋是各种文体的萌生、成长、形成阶段;明清诗文自然也有成长,甚至出现显性的发展,但这种发展是与回溯、总结相伴的。
也正因为如此,诗文二体迄于唐宋,内部结构方面的问题很多,而至明清则外部关系问题更加突出。
虽然,几乎所有称之为“外部关系”方面的问题在唐宋乃至先唐时代都有,但显然不如明清时代那样全面集中、高度呈现,这不免使人好奇。
而正如文学内部结构具有相关性一样,外部关系问题之丛生往往表现为两种形态:一是链式的,一是树形的。
前者是问题套连着问题,后者是主要问题旁生出诸多问题。
这种复杂状态尤其能够激发出研究兴趣。
因为,如欲抵达明清诗文的本真,理解其文人、文心、文本之感人处,不将诸多“外部”关系梳理清楚,。
会多少有些隔靴搔痒....②这也就是自己这些年在明清诗文研究方面比较侧重于文学与社会关系的主要原因了。
但文学社会学是一条并不平坦的道路。
我们知道,文学同时属于个人智慧、文本形式和社会结构这三个领域,从任何一个领域出发,都可能抵达文学世界。
不过应该承认,这三者与文学世界不是等距离的,而文学社会学研究较之其他方法更容易发生偏差,罗贝尔·埃斯卡皮在写作《文学与社会》时已经注意到相关问题:“真正从社会学角度出发的研究明显地被忽略了,即使在按照传统方法编写得最好的文学史教材中也是如此。
有时候作者意识到了社会维数,并试图加以描述,可是,由于缺乏严谨的、专门的方法,因而他们还是经常当了人与作品这个传统框架的俘虏。
历史的深度仿佛在一块两维屏幕上被压扁了;文学事实因此受到扭曲,就同一张世界地图在平面投影上的失真情况一模一样。
”③在1950年代以后相当长的时间里,文学社会学是学者们最习惯使用的研究方法,这一方面是受到传统的“知人论世”说的影响,一方面受到政治环境的影响。
知人论世的理念本来很好,是理性而科学性的,也是感性而人文化的,但因为被意识形态所左右,变得图式化、标签化、简单化了,文学社会学的理论意义也随之耗散殆尽。
新时期初人们一梦醒来时,它不可避免地获得了一个“庸俗社会学”的恶谥,以至于有学者明确声明:“什么方法都好,就是不能容忍社会学方法。
”尽管不断有学者将文学社会学与其他国外文艺理论、方法并论加以介绍,为其科学性与可行性辩护,但似乎总难洗白。
在研究过程中,许多研究者的课题高度接近甚或深度切入了文学社会学之要义,却仍然回避这一命名。
命名或可回避,但文学发展的史实无可回避。
④研究实践与命名的脱节,还与强调文学学科的主体性有关。
自从文学社会学在欧洲成为一个学派并产生了影响后,他们的一些社会学著作中便往往堂皇地将其作为内容设定了,使社会学的疆域得到拓宽。
虽然对这一学科发展思路无可置喙,但也不免会产生一个疑问:文学社会学是文学研究的对象,还是社会学研究的范畴?⑤其实,随着学科壁垒的打破,这个问题在宏观文学史意识中早已淡化了。
即使要细究,不少历史学著作中都专论文学家与文学发展,文学研究者以之为自然而然,如果社会学、考古学、文化人类学等学科纳入文学,又何尝不可,何损文学的学科主体性、学术自足性呢?今日学术之大、之新,往往由通、由博而生,阐他域以辅文学是好事,反之亦然,其理实不待详辩。
⑥当然,文学社会学是立足文学而借由社会学的摆渡,这与站在社会学角度研究文学还是有所不同的。
前面用了“船到桥头”的比喻,不妨还以“船”来说吧。
文学社会学的“船”上应该载有文人、文学作品、文学生活——这是一艘由文献与文心构建的“文学之舟”。
研究它与历史、时代、社会、阶层、制度、家族、社群、城市、地理等的关系,犹如讨论行船与气候、航道、水流、风力、崖岸、景观之间的影响,这是文学本体与某些客观环境的诠释与对话,其欲抵达的方向是文学史的构成及其发展规律,而不是其他。
⑦不言而喻的是,“文学之舟”要航行到目标,需要的动力因素很多,文学社会学只是多种研究方法之一,是研究合力的组成部分,尽管立足于文学,仍不免有偏至性。
这种偏至性决定了它所能够解决的只是部分问题,而不可能是全部;对文学史的构成及其发展规律的探讨,起侧翼支持或补充作用,而不能替代他翼之重要作用。

(5分)(二)阅读下文,完成8-11题。
(15分)村庄里的草木晓寒①在我的认知里,村庄是存在于一种秩序中的。
山和水,土地和房屋,各安其间,井然有序。
村庄里的草木,同样遵从于一种秩序,沿着时间的铁轨穿过风、阳光、雨水,穿过很多东西,从来不知道偷懒,也不会有所偏倚,一生都在重复一条春荣秋谢的路。
它们以不同的姿势贴近村庄,像一床被子把村庄覆盖,假使一个陌生人像翻书一样把它们轻轻地揭开,村庄的秘密便会不再缓冲地暴露在眼前。
黛色的屋顶、炊烟、牛羊,一垄一垄的稻子,弯着腰劳作的农人。
我是在草木里长大的,从来不怀疑草木的忠诚,它们不会让一个外来者轻易地窥探,习惯了用自己的枝枝叶叶,守护着村庄的私密。
②进入城市以后,我经常会在无眠的夜里找寻最初的记忆,希望以此来安慰不断入侵我内心的怀想。
但我在一番搜肠刮肚之后,发觉小时候的事情早已忘得一干二净。
我只记得端午节时插在大门边的蕲艾、菖蒲,还有缠绕的葛藤,它们看着我进进出出,有时候像恶作剧一样,借助穿堂风把泥土的气息塞进我的呼吸,令我猝不及防。
有些事情,连我自己都觉得不可信,纵使生活困窘,我的童年也应该有意想不到的斑斓,几种平常的草木,怎么就这样轻松地收买了我的记忆?③草木毫不费力地占领了我记忆的一端,但并不见得我那时如何喜欢草木。
有很长一段时间,我都觉得草木是一种不必要的存在。
我厌倦它们,它们长在路边,打湿早行人的裤脚,把枝桠伸向屋顶,吞噬阳光,堵塞瓦楞的沟壑,让雨水漏进屋来,潜入稻田和菜地,挖空心思抢庄稼的风头。
我拿着刀去砍,背着锄头去铲,用手使劲拔,连根拔掉。
我大概还想过,要是能像赶牛羊一样,把村庄里的草木赶得一根不剩,只剩下干干净净的庄稼,一条条光溜溜的泥巴路,天与地之间坦荡如砥,这样,村庄里的人便能省略大把的汗水。
就在我开始构思这个宏大理想的时候,我的喉咙突然痛了起来,没有任何征兆,痛得连喝水都要小心翼翼。
祖父见了说,没事,是上火了。
他从山上挖来一种树根熬成水端到我面前,他笑着说赶紧喝了吧,喝了就好了。
当时我并不相信这种土办法能瓦解我的疼痛,我切了一截稻草当吸管,一点点吸进去,苦,涩,酸,好像所有人类难以接受的味道都集中在这水里,弄得我头晕目眩,只是没想到几天后,竟奇迹般地好了。
④从那时起,我感到了草木的神秘,开始审视周围的草木。
村庄里到底有多少种草木呢?到处都是,没有人数得清,连年纪最大的老人也不知道。
我想它们大约是被风吹来的,一阵大风,从山那边吹过来,它们落户以后,忙着开疆拓土,攻占所有的空隙,连一条石头缝都不放过。
它们带着露水,披着烟霭,把村庄揽在怀里。
村庄累了,困了,就躺在它们的怀抱之中,草木歌唱,歌声把村庄带进沉沉的梦乡。
⑤祖父有一双巧手,他会用梧桐树皮打草鞋,半天的工夫打一双,穿上去软绵绵的。
他还会用山棕织蓑衣,用箬叶织斗笠。
我看过他织蓑衣,用一个五齿耙撕扯棕片,一点点地扯,扯出的丝像女人长长的头发,他弄一点水把手掌打湿,将丝搓成一根根细细的绳子,然后在屋坪里打开一床晒垫,把棕片铺好,操起钢针飞针走线。
他半蹲着,身子往一侧倾,右手不停地来回,钢针和绳子随着他的手穿过来绕过去,像一个老渔夫在织网一样。
偶尔他也会站起来拿着他那根长烟杆抽烟,在烟雾里打量自己的作品,似乎在想哪里要挡风,哪里要遮雨,阳光把祖父的影子压弯,像农人高高举起的镰刀。
他再一次穿针引线,好像要把阳光也一起织进去,用储存的阳光来驱赶风雨,外出干农活,穿上祖父织的蓑衣,戴上他织的斗笠,就像聪明的鸟筑了一个结实的巢,再大的风雨也奈何不了。
⑥母亲会在一家人闲着的时候,突然从屋角搬出一坛浸熟的野柿子,或者一大把板栗、煮熟的苦珠、一袋子酸枣糕。
餐桌上也经常变换花样,一碗香喷喷的蘑菇、竹笋、橡子豆腐,一盆子艾叶耙耙。
日子困顿,她以一个母亲的力量为一家人驱逐着贫穷的阴影。
霜降时节,父亲照旧从对面的山上挑回来一筐筐木炭,木炭乌黑,每一根都闪着光泽,还保留着树干的雏形,一根根木炭在寒冬里复活,变成亮堂堂的炉火,变成腊肉的香,最终停留在我们笑着的脸上。
⑦草木赐予了我们一种不可复制的生活,成为我们获取快乐的源头,离开了草木,很多的日子都将变得黯淡荒芜。
⑧岁月更迭,草木长高,村庄变矮,我在草木之下劳作,歇息,枕着泥土仰望草木,我看到阳光从它们身上流过,镶上一层绿油油的底色,我看到雨在上面冒出白烟,我看到不断改变的色彩,一万只蝴蝶的跌落,大地之上的一场蝴蝶雨。
