阅读(80分)一、阅读下文,完成1—7题(17分)中国式大众时代石勇170多年前,法国历史学家托克维尔敏锐地捕捉到,“大众”出现在了历史的地平线上,欧美将进入大众所主导的时代。

差不多半个世纪后,同样是法国人的勒庞发现,大众的理性能力非常值得怀疑。

又过了半个世纪,在1930年代,西班牙哲学家加塞特发现了“大众灾难”的秘密——纳粹德国不过是大众集体非理性的合乎逻辑的结果。

①“大众”这一概念,隐含着是“现代社会”的产物。

而我们说到以宏大叙事、激昂理想为特征的“大时代”和以个体、群体的小情趣、小偏好为特征的“小时代”,恰恰和“大众”、“现代社会”这两个概念息息相关——它们都是公共领域裂变①的结果。

②从英国工业革命时算起,包括以上的时间片段,无疑都是西方在现代化进程中的“大时代”:政治、经济、社会、文化命题宏大、高远,其间,伴随着残酷的战争。

在时代议题中,个人和小群体的趣味偏好无容身之地。

西方的现代化历程、中国从1911年到20世纪80年代的历程已经说明了这一点。

一个“大时代”,无人可以抗拒。

因为不跟随、参与、介入,个人将找不到意义,将有被抛弃感。

在“大时代”可以找到的自我面前,“小时代”的那种渺小的自我几乎不堪一击。

比如,20世纪30年代,在革命面前,一些具有“小资产阶级”情调的富家子弟,一些学生,就会感到个人的那些小情调是多么可笑。

革命所对应的“大时代”,使他们没有任何犹豫地迅速埋掉他们过去的自我。

然而按照勒庞、弗洛伊德、加塞特等人的说法,大众身上燃烧着的那些非理性的激情,极容易成为玩宏大叙事、政治修辞的领袖人物改变政治结构的能量。

毫无疑问,在这样的大众眼中,个人趣味、偏好渺小得不值一提。

Also, staring at your screen for too long can be harmful to your __33__.Being __34__ too long to your phone also can impact the quality of your relationships, he said. If you are on your phone constantly and not __35__ with those around you, it can take away from your relationships with your family and friends.

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.The scent of coffee appears to enhance performance in math Drinking coffee has benefits. __41__ the physical improvement, coffee may reduce our risk of heart disease. Coffee may even help us live longer. Now, research also reveals that the scent(气味)of coffee may help people perform better on the analytical portion of the Graduate Management Aptitude Test, or GMA T, a computer adaptive test __42__ by many business schools.The work, led by famous professor Adriana Madzharov, not only __43__ the hidden force of scent and the cognitive(认知)improvement it may provide on analytical tasks, but also expectation that students will perform better on those tasks. Madzharov, with his colleagues, recently published their findings.“It’s not just that the coffee-like scent helped people perform better on analytical tasks, which was already __44__,”says Madzharov. “But they also thought they would do better, and we demonstraded that this expectation was at least partly __45__ their improved performance.”___46___, smelling a coffee - like scent, which has no caffeine in it, has an effect similar to that of drinking coffee, suggesting a placebo(安慰剂)effect of coffee scent.Madzharov’s team tested 100 undergraduate business students, divided into two groups, with GMAT algebra questions. One group took the test in the __47__ of a coffee - like scent, while a control group took the same test - but in an unscented room. They found that the group in the coffee-smelling room scored significantly higher on the test.Madzharov’s team wanted to know more. Could the first group’s performance in quick thinking be explained, in part, by an expectation that a coffee scent would increase __48__ and consequently improve performance?The team designed a follow-up survey, conducted among more than 200 new participants, quizzing them on __49__ about various scents and their effects on human performance. Participants believed that they would feel more alert and energetic in the presence of a coffee scent, in contrast with a flower scent or no scent; and that __50__ to coffee scent would increase their performance on mental tasks. The results suggest that __51__ about performance can be explained by beliefs that coffee scent alone makes people more alert and energetic.Madzharov is now looking to explore whether coffee-like scents can have a(n) __52__ placebo effect on other types of performance, such as verbal reasoning. She also says that the finding - that coffee - like scent acts as a placebo for analytical reasoning performance - has many practical __53__, including several for business.“Sense of smelling is one of our most powerful senses,”says Madzharov. “Employers, architects, building developers, retail space managers and others, can use scents to help __54__ employees’or occupants’experience with their environment. It’s an area of great interest and __55__.”41. A. In contrast to B. Contrary to C. In addition to D. Equivalent to42. A. acquired B. required C. justified D. inquired43.

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)People generally see themselves through achievements. In doing that, they end up caring more about their image than the reality of who they actually are. Rather than their work doing the talking, they end up defining themselves by external markers that they hope will earn them respect.The problem with this is that it encourages both themselves and other people to judge their worth based on some relatively unimportant measure. For example, one day, their educational diploma may overshadow what they actually learned. Therefore, a better way to know a person, I think, is to ask a different set of questions: What motivates them? What makes them ache? What do they long for?It’s in this spirit that I want to publicly share my values. They are the compass(罗盘)that guides my life. The kindest and most sincere thing I can do is to see, recognize, and understand another person before I make judgments. From there, I can learn to treat others appropriately, depending on the context, learning from my mistakes with time and experience. It’s just a reminder that life is hard for all of us, while at the same time accepting that it’s important we are all also held accountable for our actions.I have learned that we are all deeply self-interested. I hope to be self-aware enough to check out of the power and status games. That means I’m not competing with anyone for a shiny object; I’d rather compete with myself. It’s about becoming so uniquely different that it would be aninsult for me to measure myself against someone else. I believe if I do the work to be internally free from the pull of the power and status games, then I can add value to others bused on my unique knowledge and experience.If this resonates with(与……共鸣)you, I invite you to join me on this journey in understanding and relating to this complex world. It’s a wonderful mystery, and I think together we can better define it -- not just personally, but also collectively.56. According to the article, which of the following is TRUE?A. The external markers are better ways to know a person.B. People generally judge others’ worth by what they have achieved.C. The author is someone who is keen on power games.D. Learning from mistakes is the first step of treating others kindly.57. What does the underlined word “overshadow” probably mean?A. be relatively similar toB. cause something to be stronger thanC. make something less importantD. block off light from something58. What of the following might the author agree with?A. Life is hard, so we shouldn’t criticize others when they are not responsible.B. One should overcome self-interest in order to judge others objectively.C. Everyone is unique, so showing off uniqueness is an insult to others.D. One should see and understand another person using a real compass.59. Why does the author write the article?A. To promote harmonious living.B. To ask people not to judge others.C. To call on readers to learn his values.D. To share his values of understanding the world.(B)The Elementary Science Fair Planning GuideThe most helpful, scientific, kid-friendly science Fair project planner known to kidsA Model, Display or Collection:Shows how something works in the real world, but doesn’t really test anything.Examples of display or collection projects can be: “The Solar System,”“Types of Dinosaurs,”“My Coin Collection.”Examples of models might be: “How a Tornado Forms” or “How an Electric Motor Works”.An Experiment:Lots of information is given, but it also has a project that shows testing being done and the gathering of data.Examples of experiments can be: “The Effects of Detergent(洗衣粉)on the Growth of Plants” or “Which Paper Towel is more Absorbent”.You can tell you have an experiment if you are testing something several times and changing a variable(变量)to see what will happen.Even though you can learn a lot from building a model or display, we recommend that you do an experiment! Why? Well, they are fun, they are more interesting and most of all, they take you through the SCIENTIFIC METHOD, which is the way real scientists investigate in real science labs. Besides that, the scientific method is what the judges are looking for!60. Which of the following science projects might be recommended by the guide?A. How swallows build their nests.B. What the solar system consists of.C. The three dances bees use to communicate.D. What structure can hold the most amount of weight.61. According to the guide, which of the following is TRUE?A. A model or a display is a great choice for the science fair.B. A hypothesis goes before a Question in doing an experiment.C. What tells an experiment from a model is whether to test something.D. The judges will instruct the scientific method before the science fair.62. Who will be most interested in reading this guide?A. Undergraduate students.B. Parents who have young kids.C. Staff working in the science labs.D. Judges invited to a science fair.(C)Getting active in midlife could be as good for you as starting young when it comes to reducing the risk of an early death, researchers have suggested. But experts say the study also shows that the benefits fade once exercise declines.“If you maintain an active lifestyle or participate in some sort of exercise from youth to middle age, you can reduce your risk for dying,” said Dr. Pedro Saint-Maurice, the lead author of the research. “If you are not active and you get to your 40s - 50s and you decide to become active, you can still enjoy a lot of those benefits.”The study was based on data from more than 300,000 Americans aged 50 - 71 who undertook a questionnaire(问卷)in the late-1990s. They were asked to recall the extent of their moderate to vigorous leisure exercise at different stages of their life. Researchers then used national records to track who died in the years up to the end of 2016. After taking into account factors including age, sex, smoking and diet, the team found that those who were exercising into middle age had a lower risk of death than those who had never carried out any leisure exercise. However, when the team looked at different patterns in the way people were active over their life, it found a surprise.Men and women who started exercising at the age of 40 - 50 reduced their risk of death from any cause by about 35%. The benefit was similar to that seen for people who reached and maintained similar activity from their teens or 20s onwards.However, the study found that the protective effect of exercise did not last forever. People whose levels of leisure exercise decreased by middle age had no difference in the risk of an early death to those who had always been couch potatoes. “If you have been active and you slowly decrease your exercise participation as you age, you lose a lot of the benefits that we know are associated with exercise,” Saint - Maurice said.But the study has limitations, including that it is based on individuals recalling how active they were many years before. What’s more, the research looked only at death records, not other aspects of health such as levels of sickness and disease. Nonetheless, he said, the message was positive. “This adds to the growing body of evidence about the importance of physical activity and exercise across he life course, and indicates that it is never too late to start.”63. Which of the following is TRUE about the study?A. The study took about two decades to complete.B. The study involved around 30,000 elderly Americans.C. Questionnaires and interviews were the sources of data.D. The participants in the study took regular physical exercise.64. According to the passage, what does “a surprise” (Para.3) refer to?A. The earlier you exercise, the greater your health benefits will be.B. Participating in exercise from youth to middle age benefits one’s health greatly.C. The benefit of getting active in midlife is similar to that of starting young.D. The benefits of exercising in midlife will decline once you stop exercising.65. It can be inferred from the passage that _________.A. an active lifestyle will not necessarily bring positive health benefits.B. participants’ memories may affect the reliability of the study resultC. people exercising from their teens can maintain health foreverD. women benefit more from vigorous exercise than men do66. Which of the following might be the best title of the passage?A. Exercise has its limitations, studies showB. Getting active when young, experts suggestC. Health benefits fade with age, doctors warnD. Never too old to start, researchers saySection 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.Ecotourism can put wild animals at riskEcotourism has become increasingly popular in recent years. _____67_____ There travelers visit natural environments to fund conservation efforts or promote local economies.Now, scientists have analyzed more than 100 research studies on how ecotourism affects wild animals. They find the presence of humans changes the way animals behave, and those changes may put them at risk. Therefore, they concluded that such trips can be harmful to the animals.When animals interact in seemingly kind ways with humans, they may let down their guard. _____68_____. If this transfers to their interactions with predators(捕食者), they are more likely to be injured or killed.The presence of humans can also discourage natural predators. It creates a kind of safe place for smaller animals that may make them bolder. For example, in Grand Teton National Park, elk and pronghorns in areas with more tourists are less alert and spend more time eating.____69____ “If animals become accustomed to tourists and if tourism practices enhance this taming, we might create unintended consequences - affecting the behavior or population of a species and influencing the species’ function in its community,” the researchers write.Ecotourism has effects similar to those of animal domestication and urbanization. Research has shown that domesticated silver foxes become more obedient and less fearful. Fox squirrels and birds that live in urbanized areas are slower to flee from danger. _____70_____ Scientists hope the new analysis will encourage more research into the interactions between people and wildlife. It is essential to develop further understanding of how various species in various situations respond to human interaction and under what conditions human exposure may place them at risk.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.71. High level of deforestation continuesWe are all aware of the threats our planet is facing. Experts agree that it’s mainly us humans who are responsible for the destruction of the environment. One of the most destructive activities we are carrying out is cutting down forests - deforestation. This is done for many reasons, such as providing wood for fuel, making land available for housing or for crating space for more cattle to graze(吃草)on. This has been most noticeable in Brazil, which is home to the world’s largest rainforest. Deforestation there has hit its highest rate in a decade, according to official data. Overthe course of a year, an area about five times the size of London has been destroyed.The amount of deforestation in the Amazon and in other tropical(热带的)regions has actually seen a decline but the figures are still large. Global Forest Watch say that in 2018, an area equivalent to 30 football fields were cut down every minute. Frances Seymour from the World Resources Institute says that “If you look back over the last 18 years, it is clear that the overall trend is still upwards. We are nowhere near winning this battle.”What’s special about places like the Amazon is that they are primary forests which exist in their original condition with some species of trees dating back thousands of years. This habitat is home to unique and rare animals and is critical for sustaining biodiversity(生物多样性). The BBC’s environment correspondent, Matt McGrath, says “These old forests really matter as stores of carbon dioxide, which is way the loss of 3.6 million hectares in 2018 is concerning.”Brazil has taken some steps to try and decrease deforestation by introducing government policies including fines for breaking land use regulations and illegal logging. And International campaigns to stop the trade of soy and beef farmed on deforested parts of the Amazon have also had a significant impact.Ⅴ.

three passages.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 read.(A)Julia Whelan climbed into the recording room in her home office.In preparation,she had avoided alcohol the night before,had avoided milk since waking at6a.m.and had run through the warm-up voice exercises.Whelan,38,is the calm,confident female voice behind more than400other audiobooks,as well as the narrated versions(叙事版本)of many articles.Once she has taken on a project,she reads through the book once or twice,deciding on themes to highlight when she gets into the recording room by using different tones and accents,and emphasizing certain words.“Narrating abook really is a performance,”she said,“and it can be harder to do than acting,because I can’t use my eyes or facial expressions to convey something to the audience.”As she spent time subsuming herself in the writing of others,she began to think more about her own creative ambitions.Just before the pandemic,she began“Thank You for Listening,”combining her writing with the experiences she has collected as a narrator.Writers say that Whelan has helped them understand their own work.“When I listen to Julia read my stories,it sounds like she is calling you over to tell you a great story,”said Nuzzi,whose work has been narrated by Whelan.“When I write now,I try to think like that,that I am calling a reader over to tell him a great story.It has completely changed my approach.”Whelan said that she also learns about her writing when she experiences it as a narrator.“There is something about it that changes when you’re performing it,”she said.“I read the book out loud during every stage of its revisions but it’s different when you sit down and have the microphone in front of you,whenI finally am in all the characters and the story comes to life.”36.Before recording a book,Whelan__________.A.acts out its narrated versionB.builds up strength through exerciseC.determines the focus of its subjectD.varies its emphasized words37.The underlined phrase“subsuming herself in the writing of others”(paragraph3)is closest in meaning to“__________herself in the writing of others”.A.dismissingB.involvingC.maintainingD. presenting38.How does narrating help Whelan do her own writing better?A.It enables her to think in readers’view.B.It inspires her to be absorbed in the story.C.It provides her with diverse life experiences.D.It reminds her to pursue her creative ambition.39.What can be concluded from Whelan’s experience as a narrator and writer?A.Excellent narration is based on convincing stories.B.Narrating is a more rewarding ambition than writing.C.An influential writer is definitely a wonderful narrator.D.Experiences as a narrator can change the writing approach.(B)PRIVACY POLICYThe Bundaberg Privacy Policy explains how we

first.A.attracting new sub-contractorsB.advertising its servicesC.sending bills to youD.letting you know about special offers(C)In2020,OpenAI,a research lab in San Francisco,revealed a system called GPT-3.It is what artificial intelligence researchers call a neural(神经系统的)network,after the web of neurons in the human brain.A neural network is really a mathematical system that learns skills by locating patterns in vast amounts of digital data.By analyzing thousands of cat photos,for instance,it can learn to recognize a cat.“We call it‘artificial intelligence,’but a better name might be‘finding statistical patterns from large data sets’,”said Dr.Gopnik,the Berkeley professor.More recently,researchers at places like Google and OpenAI began building neuralnetworks that learned from enormous amounts of prose,including digital books and Wikipedia articles by the thousands.GPT-3is an example.As it analyzed all that digital text,it built what you might call a mathematical map of human language—more than175billion data points that describe how we piece words ing this map,it can perform many different tasks,like penning speeches,writing computer programs and having a conversation.But there are limitations.If you ask GPT-3for10speeches in the voice of Mark Twain,it might give you five that sound remarkably like the famous writer—and five others that come nowhere puter programmers use the technology to create small snippets(一小段)of code they can slip into larger programs,but more often than not they have to edit and adjust whatever it gives them.Still,Dr.Gopnik described this kind of system as intelligent.“It is not intelligent in the way humans are.It is like an unfamiliar form of intelligence,”he said.“But it still counts.”Dr.Gopnik and many others in the field are confident that they are on a path to building a machine that can do anything the human brain can do.This confidence shines through when they discuss current technologies.He admits that some A.I.researchers“struggle to differentiate between reality and science fiction.”But he believes these researchers still serve a valuable role.“They help us dream of the full range of the possible,”he said.Perhaps they do.But for the rest of us,these dreams can get in the way of the issues that deserve our attention.43.Which of the following statements correctly describes GPT-3?A.It is meant to monitor human’s neuron webs.B.It stores limitless data in its mathematical system.C.It can identify images and employ human language.D.It studies pictures and digital books to invent patterns.44.In paragraph3,the example of computer programmers is used to__________.A.illustrate GPT-3is far from perfectB.warn programmers against technologyC.show the process of slipping code into programD.explain why GPT-3fails to find Mark Twain’s speeches45.What does Dr.Gopnik think of the mathematical system of GPT-3?A.He finds it valuable because it maximizes the current technologies.B.He doubts its worth though it is remarkably similar to a human brain.C.He thinks highly of it because it plays a valuable role in A.I.research.D.He believes it will interrupt our thinking though it differs from science fiction.46.What’s the author’s attitude towards A.I.?A.Enthusiastic.B.Opposed.C.Supportive.D. Unconcerned.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.How to show others you careThe idea that kindness can boost happiness is hardly new.Studies have shown that prosocial behavior—basically,voluntarily helping others—can help lower people’s daily stress levels,and that simple acts of connection,like texting a friend,mean more than many of us realize.___47___“I have found that kindness can be a really hard sell,”said Tara Cousineau,a clinical psychologist,“People desire kindness yet often feel troubled by the thought of being kind.”___48___They may question whether their gesture or gift will be misinterpreted,or whether it will make the recipient feel pressured to pay it back.___49___Jennifer Oldham,who lost her9-year-old daughter Hallie in July,recently created a Facebook group—Keeping Kindness for Hallie—that encourages participants to engage in random acts of kindness.People have bought groceries and donated school supplies in Hallie’s honor.“It will help your own heart,maybe even more than the recipients,”said Ms.Oldham.If you are not already in the habit of performing random kind acts,or if it does not come naturally to you,start by thinking about what you like to do.It’s not about you being like,‘Oh man,now I have to learn how to bake cookies in order to be nice’.It’s about:___50___And how can you turn that into an offering for other people?A.What skills and talents do you already have?B.Stress can also keep people from being kind to others.C.Why are recipients less likely to appreciate a random act of kindness?D.But an act of kindness is unlikely to fail,and in some instances it can create even more kindness.E.People who perform a random act of kindness tend to underestimate how much the recipient will appreciate it.F.But researchers who study kindness and friendship say they hope the new findings strengthenthe scientific case for making these types of gestures more often.IV.Summary Writing51.Directions:Read the following passage.Summarize the main idea and the main point(s)of the passage in no more e your own words as far as possible.The risk of pre-schooling“Young children learning to read is one of the most important things primary education does. It’s fundamental to children making progress in life,”says Dominic Wyse,a professor of primary education at University College London,in the UK.“While learning literacy is vital to childern, the way we teach it really matters.”In a2022report,he states that English school system’s intense focus on phonics–a method that involves matching the sound of a spoken word or letter,with individual written letters, through a process called“sounding out”–could be failing some children.A reason for this is that the tests used to assess that early learning may have little to do with the skills actually needed to read and enjoy books or other meaningful texts.For example,the tests may ask pupils to“sound out”and spell nonsense words,to prevent them from simply guessing,or recognising familiar words.Since nonsense words are not meaningful language,children may find the task difficult and puzzling.It doesn’t end up being meaningful,it ends up being memorising rather than understanding context.Children who attend intensive preschools do not have higher academic abilities in later grades than those who did not attend such preschools,several studies now show.Early education can however have a positive impact on social development–which in turn feeds into the likelihood of graduation from school and university as well as being associated with lower crime rates.In short,attending preschool can have positive effects on later achievement in life,but not necessary on academic skills.Too much academic pressure may even cause problems in the long run.A study published in January2022suggested that those who attended a preschool with a strong academic emphasis, showed lower academic achievements a few years later,compared to those who had not gained a place._______________________________________________________________________________ _______________________________________________________________________________ _______________________________________________________________________________ ______________________________________________________________________________________________________________________________________________________________ _______________________________________________________________________________ ______________________________________________________________________________第II卷(共40分)V.TranslationDirections:Translate the following sentences into English,using the words given in the brackets.52.这个问题至今已经困扰了我好几天。
