And now, a new painter is ready to join the list, although this one isn't even human.Next month, auction house Christie's Prints and Multiples will make history by offering the first piece of art created by artificial intelligence for sale. The painting is a portrait of a man called Edmond de Belamy, and is expected to be sold for up to $10,000. The work, which features a man with a mysterious look on his face, was created by software developed by the French art group Obvious. Laugero-Lasserre, an art collector from France, called the work “fantastic and amazing at the same time”. This isn't the first example of Al-produced artwork, as AI has already been used to write poems and compose songs. However, many people doubt whether it should be called art at all. According to Russian writer Leo Tolstoy(1828-1910), art is about evoking emotion. It's “a means of... joining people together in the same feelings”, he once said.So, if the emotion behind art is what makes it, the ability to create and use tools is what makes human beings different from other species. And as a tool itself, the AI technology used to create the portrait is the result of a lot of effort made by several designers. Together, they “fed” the AI with a huge collection of paintings from the 14th to the 18th centuries, until it was able to work out how to make similar paintings of its own.The introduction of AI art could be the beginning of a new artistic movement. However, not everyone is ready to welcome these high-tech artists just yet.24. Why are the talented artists mentioned in Paragraph 1?A. To make a comparison.  B. To introduce a new topic.C. To add some information.  D. To offer some background.25. What does the underlined word “evoking” in Paragraph 2 probably mean?A. Easing.  B. Controlling.  C. Creating.  D. Relieving26. What can we learn from the text?A. AI hadn't created paintings before.   B. AI created artwork for the first time.C. The price of the AI painting is the highest. D. The Russian writer thought badly of the work.27. What will be probably talked about in the following paragraph?A. Statements supporting AI art.    B. Different opinions about Al art.C. Famous artworks that AI has created.  D. AI technology used to create the portrait.CA recently ended “China and I’ writing competition, which attracted the participation of hundreds of Egyptian writers and others interested in Chinese culture, has been considered by organizers and participants as part of growing cultural exchanges between the two ancient civilizations.Organized by the China Cultural Center in Cairo in cooperation with Cairo-based Radio and Television Magazine and China Today Magazine, the second version of the Arabic language writing contest attracted some 380 competitors who wrote articles and short stories focusing on different sides of the special connection between Egypt and China.Two winners received the major prize, one won first prize, two won second prize, five won third prize, 10 got encouragement prizes and 10 earned participation prizes.

In his article, Saghir focused on different angles of the growing cooperation between Egypt and China, such as the first joint Egyptian-Chinese arche-ological assignment that has recently been working on Montu Temple at the Karnak Temple Complex and the exchange of medical aid and professional knowledge between Egypt and China regarding the COVID-19 pandemic.28.

They live almost everywhere, from rainforests to deserts. Some even spend most of their lives underwater. They are smarter than you think, with some able to make plans and count. Scientists think they might even dream when they sleep. Yet many people find these eight-legged animals scary. Now, it seems, fake news may be mostly to blame.Media reports about people's encounters with spiders tend to be full of falsehoods, a new study finds. “The vast majority of the spider content out there is about their being scary and hurting people,” says arachnologist Catherine Scott. In reality, researchers note. “Spiders almost never bite people.” In fact, many spiders protect us by eating insects, such as mosquitoes, which spread disease. Even spiders that could pose a threat rarely bite people, Scott says.For the new study, Scott and their colleagues analyzed more than 5,000 online newspaper stories about humans and spiders. Each had been published between 2010 and 2020. They came from 81 countries and were written in 40 languages. The researchers didn't just find errors in the stories. More than four in ten articles had overblown the spiders' behaviors and often used sensational words like killers and nightmares to describe them.If people knew the truth about spiders, they would spend less time blaming them for bites caused by other animals, Scott argues. People might also be less likely to kill spiders with pesticides that are poisonous to other species including humans. Clearing spiders' name would be good for them, too. Say, for instance, the ones in your house that don't get squashed (压扁) out of fear.Improving spiders' public image could even boost conservation efforts in general. “Spiders are kind of unique in that they seem to be really good at grabbing people's attention,” says Lisa Taylor, an arachnologist who was not involved in the study. “If that attention is paired with real information about how fascinating they are, then I think spiders are well-suited to serve as tiny ambassadors for wildlife in general.”32. What probably contributes to spiders' ill names?A. Scientific studies.  B. Untrue stories.C. Their errors.   D. Their ugly looks.33. What can we learn about spiders from Paragraph 2?A. Spiders are smarter than you.  B. Spiders never bite people.C. Most spiders spread disease.  D. Spiders protect people in a way.34. What can we infer from Lisa Taylor's words?A. Spiders are not good at disguising themselves.B. Spiders would be better protected if treated rightly.C. Public attention is consistent with real information.D. Improvement in spiders' public image makes no sense.35. What is the best title for the text?A. Spiders Unfairly Negative   B. Spiders' Public ImageC. Well-suited Ambassadors   D. Spiders Actually Scary第二节（共5小题；每小题2.5分，满分12.5分）根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。Minimalism is characterized by extreme simplicity. The essence of it is learning to live with fewer material possessions while still being content and at peace with oneself. Its advantages have been recognized by a wide range of people.    36    Here are a few steps you may take to get going.Set your minimalist goals.    37    What are your goals? What exactly are you seeking-a cleaner home, mental clarity, or something else? Writing down your ideas and emotions will help you come up with a set of motivations. Even better, make a vision board to describe the result you seek. If you get off track, they can help you get back on track.   38    It is a crucial step to tidy up your area. Take away anything that is broken, useless, or no longer makes you happy. Get rid of the most obvious clutter (杂物). Next, make certain that everything you possess has a home for. As a result, everything seems neater and you can further reduce your belongings.Work room by room. Breaking down the de-cluttering process into small steps is a smart idea.    39    This may be the messiest or the room you spend the most time in in the house. Go through everything you have in this area slowly, which will serve as a source of inspiration for the rest of your home once you've finished the first room.Final reflections. Keep in mind, simplicity requires patience and effort. Minimalism had to be born, not out of a short-lived idea or longing for a new lifestyle, but from a sincere desire and strong need to rethink our lives.    40   A. Remove your belongings.B. Clean up your own space.C. Decide why you choose to go on minimalism.D. Choose the space that gives you the greatest trouble.E. However, it can be difficult to start living a simple life.F. Anyway, we must develop our own brand of minimalism.G. The basic goal is to live a life that is peaceful and stress-free.第三部分  语言运用（共两节，满分30分）第一节（共15小题：每小题1分，满分15分）阅读下面短文，从每题所给的A、B、C、D四个选项中选出可以填入空白处的最佳选项。Last spring, Ada stopped at a traffic light, where a man was sitting with a sign reading “HELP!”She    41    down her window and shouted, “I'm driving around giving    42    haircuts.

What would people think of him? I put all negative thoughts aside with the determination that Mom would be able to come, and that was the end of it!When arriving home, I walked in the kitchen and smelled fresh bread. It was one of Mom's baking days! She greeted with her usual warmth, asking, “Well, hello there! How was your day?” “Nothing special. It was just another day,” I replied casually. Hearing this, her face showed her disappointment, but then her eyes kept probing (探查) mine trying to read if I was being honest. It worked. She saw there was something on my mind. “Heidi, are you sure you have no news for me?’ she continued.I explained that tomorrow was the Open Day. And Dad was walking in the back door just in time to hear the news. I quickly asked Mom, “You are free, aren't you?”“Sorry dear, I have made lots of arrangements for tomorrow. Maybe Dad will be willing to go.”“Do you want me to come with you, Heidi?” Dad asked with a smile, “I would really love that!”“Sure, Dad. That would be cool,” I said. But Dad really did not notice my lack of enthusiasm as his face brightened and he started talking about how much fun it was going to be.I loved Dad's optimism and enthusiasm. He had made life so exciting and adventurous for the family and I adored him for it. But would people see him the way I saw him? His thin body with practically bald (秃的) head was not exactly what my friends would consider a “cool dad”. Dad was also much older than most of my friends' parents. Their dads would be professional businessmen, doctors, dentists, or engineers. Dad was a draftsman (绘图员) and heworked in an office at home.注意：1.续写词数应为150左右；2.请按如下格式在答题卡的相应位置作答。Well, whether I liked it or not, the next morning came.   When we arrived, we walked into my class.     龙岩市一级校联盟2022~2023学年第二学期半期考联考高二英语试题参考答案第一部分  听力（共两节，满分30分）1~5 BCACA 6~10 CBBAB 11~15 ACACA 16~20 CBBCA第二部分  阅读理解（共两节，满分50分）21~23CDD 24~27 BCAB 28~31DACC 32~35BDBA 36~40 ECBDG第三部分  语言运用（共两节，满分30分）41~45 BADBC 46~50 ABCAD 51~55 BACCD56.before 57.to arrive 58.which 59.emergency 60.wrapped 61.a 62.firmly 63.is forced 64.with 65.slaps第四部分  写作（共两节，满分40分）第一节（满分15分）Dear Editor,I'm writing to share my experience of getting rid of my bad habit of staying up late.Previously. having great difficulty in finishing piles of homework.

Well. normally,(18) the average global temperature should be around 35℃ during summer time.

(19) and oceans will be crowded with dead bodies of sea creatures. At the average global temperature of 42℃. people will get almost nothing from land anymore. and therefore the remaining orders of the modern society will break down eventually.

We can stop global warming.【答案】A【分析】推理判断题，根据“but if we could begin to do things like using fewer private cars, unplugging the unused 10 electrical devices. protecting the forests, etc. From now on. maybe we still have a chance.”可知，如果我们从现在开始，做一些像少开私家车，拔掉10个不用的电器设备，保护森林这样的事情，也许我们还有机会。由此可推断出，说话者建议我们做出改变来保护环境。故选A。
