2019-2020学年吉林市第一中学高三英语上学期期末考试试卷及答案
2019-2020学年吉林市第一中学高三英语上学期期末考试试卷及答案第一部分阅读（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A、B、C、D四个选项中选出最佳选项AThank you. It’s my great honor to be given this award.You cannot imagine that I have always been a late starter. Years ago, when I was 16, I took an important exam — GCE(General Certificate of Education), which turned out to be a failure. My dad was reading my report card and saw that my position in class was 29th, but the number in class was 29. It meant that I had achieved the distinction of being bottom of my class.I wasn’t lazy, and I was really trying. You can picture how I felt. Dad put his hand on my shoulder and said, “You can only do the best you can, but whatever you decide to do, make sure you love it.” He was a really sweet guy and a great man. I knew his attempt to hide his disappointment with some of his encouraging words. I was depressed for a week, but his advice was a wake-up call.Fortunately I love working with my hands, and I was good at two things: woodwork and art, and I really loved to draw and paint. I was quite talented. Dad strongly encouraged me to go to art school, which in those days wasn’t the obvious place that a father would suggest.So I got into Hartlepool College of Art. The college was a revelation (出乎意料), the passionate teachers there, who were extremely interested in the students, not just tolerating them but actually engaging with them. It was a world apart from my schooling until then. It’s extraordinary what an enthusiastic teacher can do, drawing the student out, lighting independence, and encouraging a design of your own future, rather than waiting for something to happen. I’m honored to have become one of these passionate teachers years later.My teachers inspired me, and thanks to my dad, here I am tonight. I think I should mention all the talents I have worked with over time, and to my kids and my wife Giannina, thank you.Thank you for this great award. I shall find a very special place for it.1. How did the author feel after taking GCE?A. Happy.B. Upset.C. Tired.D. Relieved.2. What didHartlepoolCollege of Art impress the author most?A. The teachers were strict with students.B. The students set good examples for each other.C. The teachers inspired students’ passion for learning.D. The students got prepared for their lessons independently.3. The author gave this speech to ________.A. share his career choiceB. explain his teaching methodsC. describe his life experienceD. show his appreciationBJennifer Mauer has needed more willpower than the typical college student to pursue her goal of earning a nursing degree. That willpower bore fruit when Jennifer graduated from University of Wisconsin-Eau Claire and became the first in her large family to earn a bachelor's(学士) degree.Jennifer grew up on a farm in a family of 10 children. Her dad worked at a job away from the farm, and her mother ran the farm with the kids. After high school, Jennifer attended a local technical college, working to pay her tuition(学费), because there was no extra money set aside for a college education. After graduation, she worked to help her sisters and brothers pay for their schooling.Jennifer now is married and has three children of her own. She decided to go back to college to advance her career and to be able to better support her family while doing something she loves: nursing. She chose the UW-Eau Claire program at Ministry Saint Joseph's Hospital in Marshfield because she was able to pursue her four-year degree close to home. She could drive to class and be home in the evening to help with her kids. Jennifer received great support from her family as she worked to earn her degree: Her husband worked two jobs to cover the bills, and her 68-year-old mother helped take care of the children at times.Through it all, she remained in good academic standing and graduated with honors. Jennifer sacrificed(牺牲) a lot to achieve her goal, giving up many nights with her kids and missing important events to study. “Some nights my heart was breaking to have to pick between my kids and studying for exams or papers,” she says. However, her children have learned animportant lesson, witnessing their mother earn her degree. Jennifer is a first-generation graduate and an inspiration to her family—and that's pretty powerful.4. What did Jennifer do after high school?A. She helped her dad with his work.B. She ran the family farm on her own.C. She taught her sisters and brothers.D. She supported herself through college.5. Why did she choose the program at Ministry Saint Joseph's Hospital?A. To learn from the best nurses.B. To take care of her kids easily at night.C. To save money for her parents.D. To find a well-paid job there.6. What did Jennifer sacrifice to achieve her goal?A. Her health.B. Her chance of promotion.C Her reputation. D. Her time with family.7. What can we learn from Jennifer's story?A. Hard work pays off.B. Love breaks down barriers.C. Time is money.D. Education is the key to success.CIn 2002, young Elon Musk tried unsuccessfully to buy Russian rockets to help him send mice to Mars and back. Afterwards, the youngmillionaire decided to build his own rockets.Musk went to Southern California and started hiring people to help bring his dream to life. In a very short time, and despite some failures, his company SpaceX launched Falcon 1, the first successful privately-built liquid fuel rocket, into Earth's orbit in 2008.As the first Falcon rocket began testing, development was already underway for the Falcon 9. This much larger rocket, which uses nine engines to lift heavy payloads（有效载荷）into orbit, is engineered to return to Earth, ready to be reused for another flight.For Musk, space is the final destination. To help people get there, his company Neuralink is developing devices that will link people's brains with computers. A similar device has been developed at the University of Utah. It consists of a chip（芯片）with 256 threads（线程）that is placed between a person's skin and brain. The threads attach directly to brain tissue（脑组织）.Patients who have the device are able to use only their minds to communicate with one another through computers.Neuralink's chips will have about 1,000 threads. A robot developed by the company will place up to ten chips under a person's skin. The chips will communicate without wires but with a tiny device that will be worn behind the person's ear. That device, in turn, will communicate with computers. The primary market for the technology will be for people that, because of injuries or birth defects, cannot control their hands and arms. With Neuralink^ product, they'll be able to mentally command a computer to type messages for them or carry out other tasks.8. According to this article, what was the first Falcon 1 able to do?A. Launch big satellites.B. Reach distant moons.C. Move around our planet.D. Study the universe.9. What does the article explain about Neuralink's chips?A. How they'll be set up.B. What safety features they'll have.C. How much money they'll earn.D. Where they'll be produced.10. According to this article, who is Neuralink going to market its product to first?A. Those who own great wealth.B. Those who are physically disabled.C. Those who travel internationally.D. Those who do research on plants.11. In which publication is this article most likely to appear?A. The Journal of Environmental Studies.B. Advances in Business and Technology.C. Digest of Fashion and Entertainment News,D. Consumer's Guide to Outdoor Recreation.DAbout a billion birds die from flying into buildings each year inNorth America. Suspicions havebeen that birds may regard the open areas behind glass as safe passageways. Or they may mistake the reflected trees for the real thing.Researchers would like to reduce collisions, which requires a solid understanding about what makes a bird more or less likely to die by crashing into a building in the first place.“There was ly little known at a broad scale. Previous studies were at one small study site.'' Jared Elmore, a graduate student in natural resource ecology and management atOklahomaStateUniversity. So he and his colleagues used a previously created data set of building collisions for birds at 40 sites throughoutMexico,Canadaand theU.S.The first finding was obvious: bigger buildings with more glass kill more birds. But the details were more remarkable. "We found that life history predicted collisions. Migrants(候鸟), insect-eaters and woodland-inhabiting species collided more than their counterparts(同类).”Most migratory species travel at night, when lights near buildings can distract or disorient(使迷失方向)them. And Elmore thinks that insect-eating birds might be attracted to buildings because their insect prey(猎物)is attracted to the lights. He suspects that woodland species get tooled by the reflections of trees and bushes in the windows. The results are in the journal Conservation Biology.By understanding which birds are more likely to collide with buildings, researchers can perhaps determine the best way to adapt buildings, or their lighting, to help prevent such accidents. And by knowing risks, along with migration timing and behavior, building managers can better predict when birds are at their greatest danger - and improve lighting strategics accordingly.Elmore's next project will use radar to help predict bird migrations. " I think that would maybe go a long way in terms of providing information to people, to the public, to building managers, on when they can get the most benefit in terms of lights-out policies."12. What is the possible reason for birds' crashing into buildings?A. They didn't see the buildings.B. They took reflections for reality.C. They assumed the windows to be open.D. They considered buildings as safe routes.13. What is Jared Elmore's study different from the previous ones?A. It created a new data set.B. It went beyond national borders.C. It covered a wider range of sites.D. I’ll studied some specific bird species.14. What was the most noticeable finding of Jared Elmore's study?A. Migratory species travel at night.B. Birds tend to be misled by glasses.C. Bigger buildings cause more collisions.D. Birds living habits give rise to collisions.15. Which of the following can help reduce bird collision?A. Adjust the lightening system.B. Attach radars to each building.C. Adopt strict lights-out policies.D. Ban using glasses on buildings.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

2019-2020学年吉林市第一中学高三英语上学期期末试题及答案解析第一部分阅读（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A、B、C、D四个选项中选出最佳选项AWhen it comes to the greatest inventions of the world, China’s name is sure to be mentioned several times. There are hundreds of things which were invented by the Chinese.AlcoholShocked? I was because when they said alcohol I thought about either the US or the UK. China had never crossed my mind. In China, alcohol was made by two legendary persons named Yi Di and Du Kang who belonged to the Xia Dynasty. This period was about 2000 BC - 1600 BC. Research says that in ancient China, beer with 4% alcoholic content was widely consumed by people.TeaChina is the proud inventor of tea which was first drunk by Shen Nong, a Chinese emperor around 2737 BC. Tea production was rapidly developed, making tea a popular drink during the Tang and Song Dynasties.The Mechanical ClockHave you ever wondered what on earth we would be doing without any idea of time? A clock really is an invention without which things were incomplete. The credit of making the first mechanical clock goes to ancient China. The first mechanical clock was invented by Yi Xing in the Tang Dynasty. This was during 618 and 907.Silk FabricSilk, the favorite fabric of many girls out there, is also a Chinese invention. Although we all know that silk is made by silkworms, it was Chinese people who first invented a way to harvest the silk and then use it to make clothes. The oldest silk which has been found so far is in Henan Province and dates back to 3630 BC.1.We can learn from Paragraph 2 that ________.A.people in the US like alcoholB.beer was popular in the Xia DynastyC.Yi Di and Du Kang invented alcohol by accidentD.the author didn’t know alcohol is a Chinese invention2.The author asks the question in Paragraph 4 to show ________.A.ancient Chinese inventors were wiserB.many things in our lives are incompleteC.ancient Chinese people never wasted timeD.the invention of the mechanical clock is important3.Which of the following invention has a longer history?A.Tea.B.Alcohol.C.Silk fabric.D.The mechanical clock.BAs I was walking home，a boy seemed to be singing a song in a very low voice，walking infront of me and carrying some of the same high school books I had with me.I caught up to him，and said “Hello”．I could tell he wasstartled，and dropped one of his books.I picked it up and as I handed it to him，he said “Thank you.” in a strange way，like witha strong accent.We soon began walking together and talking.It turns out he was in my science class，and I didn’t even know it!His name was Ahmad，and his family had just moved here this school year.He invited me into his house，and his family treated me like a special guest，which made me feel very welcome.He said hospitality (好客) is very basic to his culture，and strangers were always treated very kindly.His mom brought out some great food，and offered me some tea.Ahmad’s father and two sisters wanted to hearall about me and my family，and my schooling.Ahmad’s whole family had to leave their lifelong home because war had broken out，and it wasn’t safe there anymore.They left with only what they could carry.His family was happy to feel safe，and they got used toAmerican culture quickly.They seemed pleased that Ahmad had brought a friend home to meet them.And as my friendship with Ahmad has continued，I now realize that the world is so much bigger than I thought！I also realize that your friends don’t have to be just like you.Differences make the world go round.4. What does the underlined word “startled” in Paragraph 1 mean?A. Excited.B. Moved.C. Surprised.D. Interested.5. Why was the writer treated like a special guest by Ahmad’s family?A. They liked strangers who came to their home for help.B. They wanted to know more information about the writer.C. Strangers were always treated very kindly in their culture.D. The writer was an American and knew much about their culture.6. Where does the writer probably come from?A. Canada.B. America.C. China.D. Australia.7. What can we learn from the passage?A. People from different countries can be good friends.B. Friends need different cultures and different accents.C. Your friends should have a lot of things the same with you.D. You can’t make friends with people from other countries.CIn many countries of the world, people can confidently tell youthe meaning of their town or city, but most people who live inManchester,OxfordorBirminghamwould not be able to explain what the name of their city means. The name of every British town and city, however, has a long history.Two thousand years ago, most people living inBritainwere Celts. Even the word “Britain" is Celtic (凯尔特语).Then the Romans arrived and built camps which became cities called “castra". This is why there are so many place names inEnglandwhich end in "-chester" or “-caster"Manchester, for example.The Romans never reachedWalesorScotland, and many placenames there are Celtic. For example,Welsh place names that begin with “Llan" come from the Celtic word for "church".After the Romans leftBritain, it was attacked by the Anglo-Saxons who were from the area of Europe that is nowGermanyandHolland. The names of their villages often ended in “-ham" or “-ton". Some got their names from the leader of the village.SoBirminghamfor example, means "Beormund's village”The Anglo-Saxons were farmers and the landscape was very important to them, so we have villages called Upton (village on a hill)——a good place to build a village and Moreton (“village by a lake”)where floods could make life hard. Place names that end in “-ford" (a place where you could cross a river) also describe the location of Anglo-Saxon villages.Finally, in 1066EnglandbecameNorman—theNormansgave us the place name "grange", which means farm.And how aboutLondon? Experts cannot agree. The Romans called the city Londinium, but they were not the first inhabitants (居民). People once believed that theUnited Kingdom’s capital city got its name from the castle of a King called Lud but this is very unlikely. Our best guess today is that the name comes from a Celtic word meaning a fast-flowing river. Like a number of British place names, its history is lost in time.8. The origin of British place names is unfamiliar to many local people because ofA. the death of local languagesB. the long lost history of the namesC. their lack of interest in itD. the frequent changes to the names9. According to the article,Stratfordis most likely a town .A. on a hillB. near a castleC. beside a riverD. with a church10. Which of the following shows the correct order of the arrival of inhabitants inBritain?A. The Celts—The Romans—TheNormans—The Anglo SaxonsB. The Celts—The Romans—The Anglo Saxons—TheNormansC. The Romans—The Celts—The Anglo Saxons—TheNormansD. The Romans―The Anglo Saxons—The Celts—TheNormans11. What doesLondonmean in Celtic?A. RiverB. LondiniumC. LudD. CastleDIf you have ever been disappointed because you don’t have a good gardener ,the clever robot may one day become the helper of your indoor plantsThe Hexa Plant is a six-legged robot that has been specially made to care for the potted plant that carries on top of its head .Using light and heats sensors (传感器) the robot has the ability to carry its plant in and out the daylight .If the houseplant needs more sun，the Hexa will walk into the sunlight ;and if the houseplant is getting too hot , the Hexa will go back into the area that blocks direct light The Hexa Plant will even do a little dance when it senses that the plant needs to be watered to warn its owner .The robot was developed by Vincross engineer and founder Sun Tianqi after he saw a dead sunflower sitting in the darkness in a room back in 2014 .” Plants only receive an action without responding ,”SunTianqi wrote in a blog post .” Whether they are being cut ,bitten ,burned or pulled from the earth ,or when they haven’t received enough sunshine ,water ,or are too hot or cold ,they will hold still and take whatever is happening to them .According to Sun Tianqi ,for billions of years ,plants have never experienced movement of any kind ,not even the simplest movement .In their whole lives ,they stick to where they were born .Sun Tianqi continued ,” Do they want break their own settings or have a tendency towards this ?I do not know the answer ,but would love to try toshare some of this human tendency and technology with plants With the help of the robot ,plants can experience the move”.The Hexa Plant model robots are not for sale ,though Vincross does sell a Hexa robot model .It is said that in the near future the robots can open up a new market to watch over our household plants12. What can we learn about the Hexa Plant?A. It helps people do some gardening .B. It waters the plants through dancingC. It helps indoor plants get proper sunlightD. It carries the potted plant with its hands13. What does the author try to show through Paragraph 3?A. The way plants spend their whole livesB. The common way people deal with plantsC.

Viva, ArtificialIsland.D.MarinaBayFloating Platform Stadium.BA maverick describes a person who thinks independently. A maverick refuses to follow the customs or rules of a group to which he or she belongs. In the US, a maverick is often admired for his or her free spirit, although others who belong to the maverick’s group may not like the maverick’s independent ways.But where did the word “maverick” come from?Early in the 1800s, a man named Samuel Augustus Maverick settled down in Texas, which was a place of wide-open land, rich soil, cattle ranches(牛场) and cowboys. As the years passed, Mr. Maverick increased his property(财产) in Texas. Before long, he owned huge pieces of land that were good for raising cattle. But he had no cattle. He wasn’t a rancher.One day, a man came to Samuel Maverick to pay him an old debt. But the man didn’t have enough money. So he offered Mr. Maverick 400 head of cattle. Mr. Maverick accepted them, but he didn’t really want them. He simply put the cattle on his land to eat and care for themselves.It was not long before the cows reproduced(繁殖). The calves grew and had more calves. Soon, hundreds of cows and calves moved freely across Samuel Maverick’s land. They also moved across the land of nearby ranch owners.It was a tradition among ranchers in the West to put a mark of ownership on newborn calves. They burned the name of their ranch into the animal’s skin with a hot iron. The iron made a clear mark called a “brand”. Brands allowed ranchers to easily see who owned which cattle.Samuel Maverick refused to brand his calves. “Why should I?” he asked. If all the other cattle owners branded theirs, then those without a brand belonged to him.And this is how the word “maverick” entered the American language. It meant a calf without a brand. As time passed, the word “maverick” took on a wider meaning. It came to mean a person who was too independent to follow even his or her own group.4. Why did the man give Samuel Maverick 400 head of cattle?A. To get some money.B. To return what he owed him.C. To buy some of his land.D. To ask him to raise them.5. How could the ranchers easily know who the cattle belonged to?A. Through the brand on the cattle.B. Through the name of the cattle.C. Through the appearance of the cattle.D. Through the land on which the cattle stayed.6. What can we learn about Samuel Augustus Maverick from the text?A. He was born in Texas.B. He took good care of all his cattle.C. He didn’t really want to accept the cattle.D. He followed the tradition of ranchers in the West.7. What is the text mainly about?A. How to become an independent thinker.B. “Maverick” means a calf without a brand.C. The life story of Samuel Augustus Maverick.D. How the word “maverick” got into American English.CAccording to Oxford Dictionaries, morality means: “Principles concerning the distinction between right and wrong or good and bad behavior.” Though morality is a rather subjective subject, there are some principles that are universal across all cultures found by an Oxford University study: “help your family, help your group, return favors, be brave, obey superiors, divide resources fairly, and respect others’ property”. The fact that these morals are found across 60 cultures from around the world demonstrates that morality, though subjective, is the cornerstone of keeping our societies together. Here are some reasons to be moral: without morality, a social life is almost impossible to maintain; having a good reputation and having a clear conscience is psychologically healthy; and most philosophies regard unselfish and principled behavior as important.There is no doubt that without morals, a society cannot function effectively. A confused situation would appear, According to the Society of Morality, “We are social animals, and the actions we take-the things we do and the things we don’t do-have consequences on our environments and on the others around us. As a result, we need to be able to govern our behavior in the near term so as not to injure ourselves or our community in the long term. This system of controlling our actions and our thoughts in order to operate in a community is what we often refer to as morality”. Therefore, we need a set of morals in order to operate within a social circle and a social environment. Acting immoral usually results in being excluded from social activities or being avoided by a society based on laws and cultural standards. Besides acting moral having a sociological need, it also has a psychological basis. Most people are concerned to some extent about their reputation. According to PsyPost, “A lot of economicmodels of human behavior assume that people are only rational (理性的) when they narrowly pursue their own self-interest, but history shows us that people are also tremendously concerned with being and appearing moral”. So, the fear of one’s reputation being damaged is often a strong motivator to be moral. And if someonehas been immoral,most people go out of their way to make sure no one finds out, or to correct the behavior in order to not be caught. This goes in line with conscience as well. People generally feel in a better psychological state if they feel that their conscience is clean. A dirty conscience can result in a lack of sleep, anxiety, internal stress, and even illness.On the side of philosophy, the study of ethics (伦理) comes into play. Most philosophers agree that one should rationally choose a set of standards of behavior in order to function. Though there is moral relativism, there are universal anthropological (人类学的) morals, as mentioned in the introduction. By the nature of our societies and cultures, we choose what we believe is right and wrong. But surprising, this rational behavior comes to a general agreement on morals. So, there is a fine line between moral relativism and moral absolutism. But the main thing to take away from this discussion is that philosophers generally believe that each individual has the right to rationally come up with a set of ethics to live by, and that it is healthy to do so.8. The author discusses morality (paragraph 1) in order to ________.A. explain the relationship between morality and cultureB. describe the moral rules found all around the worldC. contrast the distinction between right and wrongD. introduce the definition, principles and reasons of morality9. It can be inferred from the passage that ________.A. acting moral allows us to fit into group betterB. morality brings the system of controlling behaviorC. contrast the distinction between right and wrongD. introduce the definition, principles and reasons of morality10. Which of the following is the psychological basis for acting moral?A pursuit of self-interest. B. a clean conscience.C. The concern about reputation.D. a dirty conscience.11. What does the author advise us to do according to the last paragraph?A. To reach a general agreement on morals based on ethics.B. to carve one’s own sense of ethics to operate in this world.C. To choose between moral relativism and moral absolutism.D. To exclude philosophers’ beliefs and solution as well.DFor centuries , tea has been used for far more than quenching thirst. Around the world people drink it to relax, reinvigorate and relieve, and it's something we need now more than ever.Even in the United States, a long coffee-dominated country, tea drinking is growing in popularity, with the country consuming 0.4 kilograms (14 ounces) of tea leaves per person a year compared with 0. 36 kilograms(12. 7 ounces) in 2007 according to the United Nations, as people switch away from soda，milk and fruit drinks.Scientists are beginning to look into just how tea might affect mood and cognition. Specifically, they're investigating whether its relaxing and refreshing effects are a direct biological outcome of the compounds in tea or whetherthey come from the context in which the drink is consumed—preparing your tea, choosing your favorite cup and sitting down for a brief break from the world. Or both.Drinking green tea has been found to improve brain function in healthy people, said Stefan Borgward, chair and director of the department of psychiatry and psychotherapy at the University of Lubeck, Germany.In a 2014 study, he gave one or two cups of green tea to 12 healthy volunteers and imaged their brains to analyze changes in connectivity inside certain brain regions.“We noticed an increased connectivity in regions of the brain associated with working memory,” he said via email.And a 2017 review of more than 100 studies he coauthored found that green tea can impact the brain in three ways: It can influence psychopathological state such as reducing anxiety; cognition by benefiting memory and attention; and brain function, specifically memory.That review concluded that "it would be desirable" for more Westerners to consume at least 100 milliliters(3.3 fluid ounces) of green tea each day “to protect neurocognitive function.”However, Borgward, cautioned that the effects aren't large, and the evidence is mainly provided by small-scale studies.12. How does the author introduce the tendency of drinking in the U.S.?A. By showing examples.B. By explaining reasons.C. By making a comparison.D. By checking existing facts.13. What is paragraph 3 mainly about?A. Scientists are looking into why tea makes people relaxed and refreshed.B. The context in which the drink is consumed is very important.C. People's relaxation is the direct biological outcome of the ingredients in tea.D. Preparing tea, choosing a cup and sitting down for a brief rest is amazing.14. What can we conclude from Stefan's research?A. Tea is a cure for a neurocognitive disease.B. Green tea is particularly beneficial to our memory.C. Drinking tea every day can prevent us from getting ill.D. Westerners drink less than 100 milliliters of green tea.15. What is the researcher'sattitude towards the finding?A. SupportiveB. Doubtful.C. Unclear.D. Objective.第二节（共5小题；每小题2分，满分10分）阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。

材料三
在短短数十年里，中国已经使得近7亿人口脱离绝对贫困，是世界反贫困史上的奇迹。不过，新的反贫困运动仍有必要，因为全球化已经在全球范围内导致收入分化和社会不公平，社会矛盾激化，出现不稳定。从这个角度来看，精准扶贫是中国政府保护社会的最基本手段。也就是说，扶贫的基本目标是实现基本社会公平和正义。但是，现实中的精准扶贫往往产生着新的问题，影响社会公平的实现。因为精准扶贫基本上是一种财富再分配，就存在着一个分配给谁的问题。因为是通过分配方式进行，经常会导致村民“阶级”的再分化，产生新一类型的社会“不公平”，一般表现在不同宗族之间、家族之间、村民群体之间。一旦涉及利益分配，这些传统的因素和新产生的因素都会卷入进来，这样很容易产生新的“认同”政治。在很多地方，社会对基层官员的信任度本来就不高，“精准扶贫”是一种新的政治，搞不好容易造成新的隔离和新的对立。
D项，“文章按时间先后顺序对古诗词中柳意象的丰富含义展开论述，阐述了其发展的历史轨迹”说法错误。“时间先后顺序”“发展的历史轨迹”不正确，从全文来看，文章是按照柳具有的小同意象类型来论述的，并非按照时间顺序展开，其发展轨迹也不明显。
故选D。
【3题详解】
本题考查学生筛选整合信息，分析归纳内容要点的能力。
“柳”是中国古代诗歌中出现频率极高而且寓意丰富的意象。它经过长期的历史文化积淀而形成，主要表现在以下方面。
初春时节，柳树的枝条上就已绽出了粒粒新芽。柳树早早地将春的讯息传递给人，也带来了春的喜悦。王维《田园乐（其六）》：“桃红复含宿雨，柳绿更带朝烟。”用桃红、柳绿与烟雨描摹了一幅生机盎然的春景图。自汉代以降，“折柳”之风俗流行开来。因“柳”与“留”谐音，“丝”与“思”谐音，故古人借“柳”传达送别之人对离人的无限相思之情。古人喜欢种柳，无论是家中庭院，还是河畔池边，遍植柳树。故“柳”常作故乡的象征，寄寓着人们对故土的眷念和对家园的依恋。唐代许浑《咸阳城西楼晚眺》：“一上高城万里愁，蒹葭杨柳似汀洲。”开篇即写自己登楼晚眺，见到蒹葭、柳树这些生在水边的景物，勾起自己对故乡无限思念的客居之愁。
