Dog fighting had cruelly taken away his left ear. In 2019, the 4-year-old arrived at a shelter in North Carolina and was then named Van Gogh. Christy Langley explains he was named after the famous painter “not because he is an artist, but because he is a work of art”. What Langley couldn’t predict was that Van Gogh would actually go on to be a successful artist.Gartner owns a shelter that helps dogs in shelters that are at risk of being put down. She saw Van Gogh and immediately knew she needed to help him. So, she took Van Gogh in from North Carolina in June 2022. Gartner started telling everyone about the friendly and lovely dog on Facebook, Pet Finder, and Rescue Me, but no one responded.After months of searching for a new owner, Gartner had a new idea. Why not take Van Gogh’s name literally? Gartner explained, “He certainly had the name and the ear for it.” Gartner got to work, putting some paint on a canvas(油画布), wrapping it in a plastic bag, and coating it with peanut butter(花生酱)as a tasty treat for the pup. It only took five minutes for Van Gogh to lick the plastic-coated canvas clean and for a work of art to be created.They worked on paintings for about a week and then, Gartner invited people to an outdoor art gallery event on October 23, 2022. Sadly, only two people showed up. The next day, Gartner put out a post on Facebook that she felt bad only two people showed up, and said the rest of the paintings were still waiting for their owners. Suddenly, Van Gogh’s pieces were hot items. After two minutes, the paintings were sold out and Gartner raised around $1, 000 for her rescue. The biggest success of all, though, was that on the last day of the silent sale, Van Gogh was finally adopted(收养).4．What is Van Gogh?A．A dog owner.B．A boxer.C．A rescuer.D．A dog. 5．What do the underlined words “put down” mean in Paragraph 2?A．Killed.B．Expanded.C．Protected.D．Valued. 6．How did Van Gogh create his works?A．By painting with a brush in his mouth.B．By licking a plastic-coated canvas.C．By running on a canvas.D．By wrapping a plastic bag.7．What did Gartner do when she found few people were interested in the paintings?A．She gave up.B．She invited more people.C．She tore up all the paintings.D．She posted a post on social media.Is it the future that worries me? Did I hurt someone by mistake? Am I expecting too much from life? We are often stuck in these unnecessary thoughts, causing anxiety and making us weak.What helps me escape from my sadness and depressed thoughts is cooking. I read through quick recipes, find the ones that I can connect to, and search for materials in the kitchen. Every time I cut a vegetable, it is like I am cutting off my problems. All of this not only brings me great joy, but it leads me to discover something I am good at, which I might have never tried otherwise.Cooking can work as a treatment, which has received some scientific explanations. Mental health experts have talked about the benefits cooking and baking provide for people struggling with poor mental health. Through cooking, these people can get back control of their lives. They can bring back the feeling of joy and excitement that has been long gone from their daily lives. Julia Ohana, an active expert in culinary therapy (烹饪疗法), talked about the significance cooking holds in terms of time control, communication, and problem-solving ability. She believes all these skills combined help people become less depressed and more satisfied.The excitement when you work on a recipe is unexplainable. You look forward to what you are going to create from your own hands. You have the power to make something great, only depending on the direction you take and your cooking skills.8．What might be the result if we are caught in unnecessary worries?A．Forcing us to work harder.B．Making us hurt others.C．Pushing us to look into the future.D．Causing anxiety and making us weak.9．How does the author deal with his sadness and depressed thoughts?A．By cooking.B．By walking.C．By sleeping.D．By reading. 10．What benefits will cooking bring to people with poor mental health according to the experts?A．Bringing them a lot of money.B．Making them become perfect in their work.C．Making them willing to cooperate with everyone.D．Bringing the feeling of joy and excitement back to them.11．What does the author probably suggest people do to get rid of unnecessary worries?A．Cook.B．Eat out.C．Do sports.D．Go shopping.Have you ever been on social media and seen your favourite celebrity (名人) talking about a product? These endorsements (代言) might not be totally random, and are actually seen as a vital part of the marketing process. The question is: How do social media influencers ‘influence’ what you buy?The human desire for status and making friends, combined with our need to belong to a group, make us susceptible (易受影响的) to being ‘socially influenced’. Companies often use that desire to have a similar lifestyle to a celebrity we admire to sell or launch a product. So, what do these endorsements actually do?Firstly, they can be used to build brand awareness. A social media influencer should have a strong understanding of the platform they operate on, and therefore can create appealing content that not only stays with the brand image, but stimulates (激发) their followers’ interests in a product they might never have seen before.Secondly, influencers can improve a company or product’s relationship with their customer base. According to InMoment’s 2018 US Retail CX Trends Report on customer loyalty, 77% of buyers have been brand loyal for more than ten years. This is also true of 60% of millennials. A popular celebrity can target key customer groups and talk or blog about a product, which can create an instant and lasting bond with the consumer.Lastly, influencers can improve customers’ buying habits with seemingly ‘just opinions’. We are more likely to respond to “peer recommendation’ than traditional ads, meaning the fact we see an influencer as a ‘friend’ can make us less likely to be doubting about what we are seeing.So, the next time you see a celebrity talking about a product, you-might want to consider that this could be a carefully crafted marketing strategy designed to target your main needs. If you find yourself examining a product you’ve seen on social media, you may well have been influenced.12．Why is ‘social influence’ so effective?A．Because a celebrity will not lie to his followers.B．Because product endorsements might not be totally random.C．Because social media influencers are knowledgeable and reliable.D．Because people long for status, making friends and belonging to a group.13．How does an influencer make a new brand known among his followers?A．He makes friends with his followers.B．He tries his best to improve the quality of the product.C．He creates attractive content to spark his followers’ interests.D．He improves his buying habits and introduces them to his followers.14．What should we do when a celebrity is talking about a product?A．Buy it without hesitation.B．Consider it carefully.C．Refuse to buy it directly.D．Neglect and forget it.15．Which is the best title for the passage?A．How Do Social Influencers Affect Our Buying?B．How Should We Treat Celebrities?C．Should We Believe in Celebrities?D．Should Online Products Be Recommended?二、七选五Body Language Mistakes You Should Avoid at WorkCommunication is not only about words but also gestures. Therefore, you should be careful about how you use your body when expressing yourself.Avoiding eye contact (接触).When speaking with a workmate, avoiding eye contact makes you look unprofessional (不专业的). It also shows that you are not confident or show no interest in the topic. 16 Crossing your arms.Crossing your arms shows that you are not open to others and that you want to defend yourself. This is generally considered as a position of defence. 1718Checking the time every few minutes makes people feel you are in a hurry or would rather be somewhere else. It looks like you are not interested in being there. Therefore, when you are speaking to your workmates, try not to look at the clock very often.Bad body postures.Having a bad posture such as dropped shoulders or a lower neck can mean that you are not interested in what is going on around you. It is important to stand or sit up straight when speaking to somebody. 19Weak handshake.A weak handshake means that you don’t care much about the person you are shaking hands with. 20 However, don’t forget that a handshake that is too firm can be impolite. Therefore, try to find the right balance.A．Checking the time.B．Also, keep your head high.C．Nod your head to show that you are listening.D．This shows that you have’ confidence in yourself.E．Try to greet the people with a firm handshake.F．In order to give others a warm feeling, just keep your arms open.G．Therefore, you should always keep eye contact especially when you are making a point.三、完形填空It all started about three years ago, when I met up with my son in a park.

Cumbria is often called the English Lake District. So apart from copper hills, green and red woodlands and pine trees, you’re also guaranteed beautiful mirror reflections of autumnal scenery in the multiple lakes around here.Bruges, BelgiumThose pretty buildings wrapped in vines that go all shades of crimson in the autumn — it’s a feast for your eyes. And the canals, you have to take a boat ride through the canals when you’re there — it’s incredible. Plus, they have the most charming open air markets that work all the way until the end of November, and it’s also a great opportunity to taste the best chocolate you’ll ever have in your life.Bavaria, GermanyWhat makes Bavaria a great fall travel destination?

She showed athletic talent since childhood and was selected as a track and field athlete by Jiangxi Disabled Persons’ Federation.Although she can’t see the world, Jia breaks through the “immediate” obstacles again and again while running, letting the world see her. In her sports career, Jia has won 43 national and world-class sports medals. Among them, in 2016, she broke the world record and stood on the podium(领奖台)of the women’s T11-T13 4×100-meter relay event at the Rio Paralympics.In 2017, Jia retired and chose to become a teacher at a special education school. Just a year ago, she found out that two young brothers, with visual impairments(视觉障碍), wanted to be an athlete. They had never attended a special education school and never achieved their athletic dream. Jia could only help them attend a local special education school. The experience made her realize that these children living in remote areas may have little knowledge of special education. Even she didn’t know about such schools until late into her education. As a result, she decided to become more involved with special education.Changing from a Paralympic competitor to a special education teacher, Jia said that there is no discomfort, “Because I understand the students as well as myself and knows the inconveniences and difficulties of the children. I hope that every child is like a different seed. Through hard study, they can bravely realize their own life.”Jia also has paid close attention to the rights and interests of disabled people. In 2021, Jia proposed the construction of audible traffic signals for blind people. Her advice to local authorities on dog management has resulted in more indoor public places allowing the disabled to enter with their assistance dogs. Jia and her husband founded a massage(按摩)shop and currently employ 16 visually impaired people, with an average monthly salary of 3500 yuan per person.Jia always believes that the world is a circle, as long as the love of others is constantly passed on, the whole society will be full of love!4．What is paragraph 2 mainly about?A．Challenges in Jia Juntingxian’s sports career.B．Jia Juntingxian’s achievements in sports competitions.C．Reasons for Jia Juntingxian to be a field athlete.D．Jia Juntingxian’s efforts to win the Rio Paralympics.5．What made Jia devote herself to special education?A．The good salary at the local school.B．Her desire for enriching her life after sports.C．The difficult situation of disabled children.D．Her responsibility of looking after her brothers.6．How has Jia improved the life of disabled people?A．By offering them working opportunities.B．By designing more traffic signals for them.C．By organizing long-term volunteer services.D．By giving advice on training their assistance dogs.7．Which of the following words can best describe Jia Juntingxian?A．Caring and cautious.B．Patient and generous.C．Humorous and brave.D．Kind-hearted and helpful.Banff National Park is home to an amazing wildlife population. But the busy Transproblem, Banff first put-up wildlife fencing on either side of the highway to discourage animals from entering the busy road. Then, since 1996, they’ve opened six wildlife overpasses and 38 underpasses to help the animals cross the highway in safety. I was fortunate to visit Banff’s Red Earth Overpass with Trevor Kinley, the project manager with Parks Canada. He told me that so far, they have documented 10, 000 safe animal crossings on this overpass alone. “ Some animals have learned how to use the crossings much more quickly than others. Black bears are the fastest learners, followed by deer. Wolves and lions take the longest to work out how to use them, ” Kinley said, laughing. “ But those animals that are slower to adapt are usually more capable and determined at figuring out the safest way to cross those overpasses and underpasses. ”There is some criticism (批评) that channeling so much wildlife into a few bridges andtunnels is like making a trap for the animals, offering big animals an easy meal on either side. “ But research has shown that this is not the case, ” Kinley assured me. “ There are no more killings around the crossings than there are anywhere else in the park. ”Walking over the Trans Canada and then walking underneath through one of the tunnels, I was amazed to see the fresh tracks of black bears, wolves, deer and many kinds of smaller animals. Somehow, all these animal footprints made me so happy, knowing that all this wildlife was passing safely under and over the longest road in Canada.Hopefully, the success of the wildlife crossings in Banff will continue to inspire similar solutions around the world, where human pressure on wildlife continues to grow.8．Which of the following best explains “ hazard ” underlined in paragraph 1?A．Shelter.B．Message.C．Answer.D．Danger. 9．What does Trevor Kinley say about those wolves and lions?A．They are stupid animals.B．They are cautious learners.C．They are very dangerous.D．They are good at adapting.10．What are the critics worried about?A．There are too many bridges and tunnels.B．Many animals will not use the crossings.C．More killings might happen at the crossings.D．Illegal hunting might beencouraged in the park.11．How does the author feel at the end of the visit?A．Concerned.B．Disappointed.C．Shocked.D．Delighted.Researchers from the Swiss Federal Institute of Technology in Lausanne (EPFL) said they have completed the most detailed virtual reality (VR) map of the universe ever created. The map permits users to “travel through space and time”. With the help of VR headsets, users can visit places in the universe virtually. The software program is called the Virtual Reality Universe Project, or VIRUP.The researchers said they combined the largest data set of information about the universe to create the 3D experience.People can see the virtual universe through VR equipment or with 3D glasses in a theater. Jean-Paul Kneib, the director of EPFL’ s astrophysics laboratory (天体物理学实验室) , said that one of the best parts of the project was putting together parts of the data set “into one framework”. “You can see the universe at different scales一nearby us, around the Earth,around the solar system, at the Milky Way level,” Kneib said.VIRUP produces images that can appear as close as one meter or seemingly at an infinite (无限的) distance. It aims to get many kinds of visitors. This includes both scientists looking to get a virtual picture of the data they collect and people seeking a new way to explore the universe. There are different versions of the software. A smaller version is aimed at the public and a larger one is meant for scientists or astronomy experts.The project combines information from eight databases. It includes at least 4,500 known exoplanets (外星行星) ,tens of millions of galaxies (星系) and hundreds of millions of space objects. More than 1.5 billion light producing objects from the Milky Way alone are included. The researchers expect to continually add data, meaning the virtual experience will keep getting better with time. Future databases could include space rocks called asteroids in our solar system or farther objects in our galaxy.Yves Revaz, an astrophysicist of the EPFL, called the system “a very efficient way of visiting all the different scales that compose our universe.” Revaz added: “A very important part of this project is that it’s a first step toward treating much larger data sets which are coming.”12．What can people do through the software program?A．Visit the Milky Way for real.B．Travel to the past through time.C．View the universe with VR equipment.D．Explore the formation of the solar system.13．What do we know about VIRUP from paragraph 3?A．It allows users to download 3D images.B．It combines different databases into a whole.C．It is accessible to both astronomy experts and common people.D．It guides scientists to adjust the distance for detecting objects.14．What is paragraph 4 mainly about?A．The limitations of the project.B．The signifcance of the project.C．The different versions of the project.D．The huge data source of the project. 15．What is Yves Revaz’s attitude towards VIRUP?A．Negative.B．Positive.C．Uncaring.D．Doubtful二、七选五The age range between about 13 and 19 is an important time in an individual’s life.Taking on the right amount of responsibility and independence can push you towards becoming a successful teenager.First, participate in extra-curricular activities. Schools give students opportunities for staying active. Pick an activity that appeals to you such as athletics, academic clubs, or special-interest clubs. Extra-curricular activities build character through team work, time-management, and competition. Don't be too worried if you aren't very good at what you like, for the important thing is passion. 17Besides, volunteer. 18 Meanwhile, volunteering can teach you job-related skills such as responsibility or time-management. Some schools also reward the learning aspect of volunteer work with credit hours. If you are interested in college, volunteering makes you much more appealing during the application process.Third, use your summer for academic programs. Getting a head start at college could mean sacrificing your summer vacation. Various universities offer programs for future college students based on interests such as journalism, photography, art, sports, etc. 19 Research different programs and then figure out which one is the best choice for you. Check the requirements and deadlines. Avoid getting into trouble because of a simple mistake, and you will have a great time.Finally, know when to ask for help and advice. Being responsible and independent does not mean being alone. 20 So, seek advice from parents, older siblings, advisors at work, teachers, or someone whom you trust. Opening up channels of communication at a young age is a great habit for success.A．Make sure your maturity level and interests are leveled.B．Making and meeting goals can motivate you to progress.C．Huge steps are taken within that period.D．They give teenagers the chance to earn college credits.E．Offering help is a symbol of kindness.F．It will drive you to put in your best effort.G．Taking on new tasks and meeting goals will be hard work.三、完形填空with other house pets: chickens and cats.

云南省昆明市五华区云南师范大学附属中学2023-2024学年高二上学期期末考试语文试题学校:___________姓名：___________班级：___________考号：___________一、现代文阅读阅读下面的文字，完成下面小题。

材料一：什么是经典？常念为经，常数为典。

经典就是经得起重复，常被人想起，不会忘记。

经典的书，人们一遍遍地读，一代代地读。

不但文字的经典这样，就是音乐、绘画等一切艺术品都是这样。

许多人都在梦想自己的作品、事业成为经典，好让自己被历史记住，实现永恒。

但这永恒之梦，总是让可怕的重复之斧轻轻一劈就碎。

修炼不够，太轻太薄，不耐用甚至经不起念叨第二遍。

倒是许多不经意之说、之作，无心插柳柳成荫，一不经意间成了经典。

当然，经典也有呕心沥血、积久而成的，像米开朗琪罗的壁画《末日的宣判》，一画就是八年。

不管是妙手偶成还是苦修所得，总之，它达到了那个水平，就如铜镜愈磨愈亮，要是一只纸糊灯笼呢？用三五次就破了。

经典所以经得起重复，原因有三：一是达到了空前的高度；二是有绝后的效果；三是上升到了理性，有长远的指导意义。

经典不怕后人重复，但重复前人却造不成经典。

文化的发展总是一层一层，积累而成。

在这个积累过程中要有个性，能占一席之地必得有新的创造，唐诗、宋词、元曲，书法的欧、颜、柳、赵，王羲之的行书、宋徽宗的瘦金书都是中国文学艺术史上的经典。

因为在这之前没有过，实现了“空前”，有里程碑的效果。

它们是永远的参照点。

经典又是绝后的，你可以重复它、超越它，但不能复制它。

后人时时地想起、品味、研究经典的目的是为了吸收借鉴它，以便去创造自己新的经典，就像爱因斯坦超越牛顿，爱因斯坦和牛顿都不失为经典。

齐白石谈到别人学他的画说：“学我者生，像我者死。

”因为每一个经典都有它那个时代、环境及创造者的个性烙印。

你只能创造你自己的高峰。

唯其这种“绝后”性，才使它高标青史，成为永远的经典。

我们对经典的重复不只是表面的阅读，更是一次新的挖掘。
