While having trouble drifting off to sleep isn’t unusual, it still can be frustrating. Fortunately sleep experts are gaining an increasingly strong understanding of what’s happening in the brain during the process.Falling asleep is a big shift for your brain. This switch is governed in part by environmental cues, such as light or temperature. A hot summer night or a bright streetlamp beside the window can interfere (干扰).The process of nodding off can also be affected by your emotions. “You need to feel both physically and psychologically safe to sleep,” says Roxanne Prichard, a neuroscientist at the University of St. Thomas, Minnesota. “If you are sleeping next to someone you don’t trust, if you’re worried that the newborn that you’re caring for might stop breathing, it’s going to be hard to fall asleep.”One of the recommendations to address insomnia is getting out of bed and sitting somewhere quietly with dull light and just relaxing, doing something boring. You could use the time to read, listen to calming music, or do breathing exercises — anything that slows and comforts your body and mind. But avoid snacking, exercise and screens.It’s also important to resist the urge to concentrate on your worries, especially in the middle of the night. Not only will those thoughts keep you awake, you also probably won’t make much progress on what’s keeping you up because your prefrontal cortex (前额叶皮质), a part of the brain that is good at planning and analysis, doesn’t function well for the poor blood supply at night.Keep it in mind that even if your night’s rest is incomplete, avoid the urge to make up for it by sleeping in or napping the next day. “If you nap during the day, especially longer naps, then your brain gets few signals of sleep and will be less likely to fall asleep quickly at bedtime,” says Prichard. If losing sleep interferes with your ability to function during the day, which could indicate something physiological is at play, seeing a doctor would be necessary.4.Which of the following is most likely to cause trouble in sleep?A.A slow soft tune.B.A dull streetlamp.C.A cool summer night.D.A two-day-old baby.5.Why is it hard to make much progress on the concerns in the middle of the night?A.The resistance may make people worried.B.The brain can’t plan and analyze problems.C.The prefrontal cortex works less efficiently.D.The problems may keep people awake. 6.What’s Prichard’s attitude towards naps in the day for night’s incomplete rest?A.Opposed.B.Ambiguous.C.Supportive.D.Neutral. 7.What’s the author’s purpose in writing this passage?A.To highlight the negative effects of sleep loss.B.To illustrate the process of falling asleep in the brain.C.To explain the causes of poor sleep and offer solutions.D.To discuss the importance of a good sleep environment.While there are several easy ways to help protect yourself against mosquito-borne diseases, there’s another solution that sounds appealing: What if we could just make all the mosquitoes disappear?Plenty of research has revealed food webs of bigger mammals, such as lions or leopards. And for good reason — they’re much easier to observe than tiny mosquitoes, which often breed in pools of water. Mosquitoes of all ages and sexes serve as a food source for all kinds of creatures, such as fish, turtles, migratory songbirds, and bats. Moreover, males in many mosquito species eat only nectar (花蜜), making some species major pollinators (传粉者) of plants such as some crops and flowers.Perhaps more than any other animal, bats are often regarded as being the mosquito’s greatest threat. Surely removing all the mosquitoes would affect bats more than most? Not so, saysWinifred Frick, a bat biologist at the University of California, Santa Cruz. Most bats actually eat whatever they can catch — mosquitoes, beetles, or otherwise. “There aren’t any bat species that specialize specifically on mosquitoes,” says Frick. In fact, some mosquito species are most active during the day, meaning bats would have very few opportunities to feed on them at all.The disappearance of mosquitoes would have massive consequences for global health, however. In all, mosquitoes account for more than 700,000 human deaths each year. Mosquitoes are the primary cause for malaria. But we might not need to wipe out mosquitoes to turn around the situation. In recent years, researchers have made promising breakthroughs in preventing disease spreading by infecting mosquitoes with parasitic (寄生的) bacteria, which can make mosquitoes less harmful to other creatures.And it’s important to remember that not all mosquito species are responsible for the destructive diseases. In fact, many want nothing to do with us. “There are some species that live in wetlands that will feed mainly on frogs and other amphibians,” says Michael Hutchinson, a professor in insect research. There are also mosquito species not known to be bloodsuckers. In fact, they actually hunt other mosquitoes during their early stage.8.What’s the function of the question in the first paragraph?A.To raise doubts about the new appealing way.B.To arouse further thinking and introduce the topic.C.To encourage readers to give specific answers.D.To inform readers of mosquitoes’ disappearance.9.What statement may Frick agree with?A.Bats take mosquitoes as the greatest threat when hunting.B.Bats need to seek new habitats when mosquitoes are gone.C.Bats may not be severely impacted without mosquitoes.D.Bats will face extinction owing to the lack of mosquitoes.10.What does the underlined phrase “turn around” mean in Paragraph 4?A.Develop rapidly.B.Maintain properly.C.Reduce greatly.D.Improve gradually.11.What can be done to prevent mosquitoes spreading diseases according to the passage?A.Infecting other creatures with parasitic bacteria.B.Hunting mosquitoes which feed mostly on frogs.C.Applying bacteria to mosquitoes to reduce harm.D.Killing all mosquitoes responsible for the diseases.ChatGPT maker OpenAI from the United States stepped up the global artificial intelligence (AI) race when it published its text-to-video generation tool Sora, which is capable of generating complex scenes with a very high degree of accuracy, including multiple characters, specific types of movements, themes and backgrounds.This made Chinese people think about the gap in AI technology between China and America. An significant question was raised: Will AI become China’s new productive force?On Feb. 16, Zhou Hongyi, founder of cybersecurity firm 360 Security Technology, said Sora may bring a huge disruption (扰乱) to the advertising industry, movie trailers and the short-video industry; what’s more, the realization of generative AI may be shortened from 10 years to one or two years. “Although the development level of large-scale models in China seems to be close to GPT-3.5, there is still an 18-month gap compared to GPT-4.0. “Besides, the AI technology in America should still have secret development, whether it is GPT-5.0 or machine self-learning to generate content,” Zhou said, adding that it is worth paying attention to.However, China has a broader market for the application of AI technologies. Or, to put it simply, China needs to apply such technologies to real use, and develop them into productive forces, narrowing the gap between itself and the US.Jia Jiaya, founder of smart manufacturing (制造业) company SmartMore, told that GPT-4.0 is less efficient in the industrial sector and that’s where Chinese companies found opportunities. China is the only country now in the world that has developed all the industrial categories. China’s supply and industrial chains offer comprehensive services from raw material supply, component production, distribution, assembly, processing and logistics to final delivery to consumers. It means that any technology will have its best application prospect here in the Chinese market, and without application or commercial use, technology means zero.12.What does the underlined word “this” refer to in Paragraph 2?A.The appearance of advanced AI tool, Sora.B.The race of artificial intelligence.C.The generation of complex scenes.D.The high degree of operation accuracy.13.What can we learn about the AI development in the US from Paragraph 3?A.Sora may bring a huge disruption to local industries.B.Generative AI has already been put into practical use.C.The AI development in the US is 18 months ahead of China.D.Its development level may be beyond what the world knows.14.According to Jia Jiaya, why can China find opportunities in the industrial sector?A.China’s AI technology is more advanced than America.B.China can offer the most promising application future.C.China has applied AI technologies to all industrial categories.D.China possesses the largest group of consumers in the world.15.What is the best title for the passage?A.AI: China’s New Productive Force B.Sora: A New Step for the WorldC.Manufacturing: A New World for AI D.ChatGPT-4.0: A Gap Between China and AmericaIt can be challenging to force yourself to start a bunch of productive habits out of nowhere. Luckily, with a few minor changes, anyone can set the stage for success. 16 . With the right attitude and a little effort, you’ll be crossing tasks off of your to-do list faster than you can write them out!Use a daily planner17 . Being productive has more to do with organization than effort, so put 5-10 minutes aside every night (or morning) to map out how you’re going to spend the day ahead ofplete important tasks before lunchMost people are more productive in the morning, so do key tasks early. If you want to pitch a new service to a few important clients, make those calls before noon. If you’re struggling to maintain your energy later in the day and you aren’t at work, take a short rest. 18 .Declutter your home or workspaceA clean desk and an organized home will help you stay focused. 19 . At the end of each day, spend a few minutes throwing out the trash, putting things away, and organizing your workspace or home to get rid of clutter. 20It’s hard to be productive if you think you’re doing something pointless. Start pushingyourself to find the significance in every single thing you do before you start. If you walk around all day feeling like you’re wasting your time, you’re never going to get anything done!A.Find the value in the boring stuffB.Reward yourself for building habitsC.Mapping your day out will keep you focused on what’s importantD.All it takes is a little bit of preparation and a healthy dose of positive thinkingE.A 20-minute nap is a great way to put yourself back into a productive headspaceF.It may be hard to push through that first week if you aren’t used to doing something G.Chaos has a way of drawing your attention away from whatever task you’ re trying to do二、完形填空When informed that I was to stay in the hospital for a few days for treatment, I never expected it would be such a wonderful experience.A young doctor friend 21 me after his long day, remembering that I had mentioned consistent stomach pain.

一、现代文阅读(35分)(一)现代文阅读I(本题共5小题,17分)阅读下面的文字,完成1~5题。

材料一:中国现当代文论与西方文论关系的密切程度明显要高于其与中国古代文论的关系。

在这一事实前提下解决现当代文论“失语”的问题,首先要厘清现当代文论的产生背景,客观审视其与西方文论的关系。

尽管多数学者都认同中国现当代文论的产生,一方面源于整理国故的内在驱动,一方面来自西方文学经验的异域激荡。

但平心而论,在近现代文学变革之际,西方文论对中国文论的影响是压倒性的。

而其后的半个世纪里,苏联的文学理论又对于中国现当代文论的发展产生了决定性的影响。

进入20世纪80年代中期,西方世界的诸种文学理论纷至沓来。

一时间,中国文学批评领域俨然成为这些理论的试验场。

实际上,每种理论都有其产生的背景、适用的范围以及存在的局限,不可能直接采取“拿来主义”,包打一切。

因此,这期间的新潮迭起虽然声势浩大,但是对于中国现当代文论的建设而言,却是丧失了一段自主发展和民族化转型的宝贵时间。

学界常言的中国文论“失语症”,原意是指中国现当代文论至今没有一套自主自足的理论体系,并非指称古代文论在当下的失语状态。

毕竟,古代文论的批评对象终究是古典文学作品和文学现象,不可能完全适用于现代白话文作品,其中“虚实”等具有生命力的概念、范畴或命题自然会存活在当下的文论话语之中,而那些伴随时代变迁已经走入历史的理论和概念也没有激活的必要。

天一小高考2024-2025学年高三上学期第一次考试语文试卷及答案

天一小高考2024-2025学年高三上学期第一次考试语文试卷及答案

天一小高考2024—2025学年(上)高三第一次考试语文试题一、现代文阅读(35 分)(一)现代文阅读Ⅰ(本题共5 小题,19分)阅读下面的文字,完成1~5题。

材料一:“木削展览碍不着我,我的领域是文艺”,这话讲不通。

一个想养成品味的人不但要无成见地亲近一切伟大著作,还要去欣赏一切其他艺术,因为艺术本是相遇的。

贝多芬的《第先文响曲》并不和斯文朋的诗两样,明白中国绘画的人去了解印象派的作品容易多了虽然各门艺术在形式上的表现方法不同,最终的求“美”企图却是一致的。

在没有新式剧院的中国,想明白舞台剧艺术的人连好电影也不可不看的。

因为这些都能帮助你把捉一个不易把捉的东西——什么是关.怎样才是艺术。

为什么一个曾欣赏了许多伟大作品的人,有时看到了像《埃及皇后与安托尼)一类历史剧时仍不能产生满意的反应呢? 因为他缺乏《罗马史》的知识,因而历史的想象也薄弱。

所以有了高尚的品味还须取得辅佐那品味的知识。

当然,一个批评光学的人须懂得物理。

但即使批评并没有那么明显知识的书时——像小说,知识也还是需要的。

对于“五四”以来中国新文学的演化毫无历史观念的人哪里配安排作品的位置!而批评的工作一部分即在安排。

(子夜)在茅盾创作过程上及在新文学史上的地位是怎样呢? 对于世界的文艺史也不可马虎的,因为在这世纪里,“中外”已成了休戚相关的一体了。

一个不以专门著作为对象的书评家所应具备的只是“各科常识”,一个坚实的文化背景为书评家及一切新时代公民的随身宝。

与其说得懂这些书,毋宁说得懂生活中的人情道理。

就算不做书评家、你可以忽略国际联盟的现状或人类行为规律吗? 总之,只在书中耕耘是不妥的。

一个理想的书评家要具有足用的知识和品味的背景,对于实际生活又怀有莫大兴趣。

历史沿革对于他来说不生疏,而拾起每本书来,他仍能保持涉猎的好奇心,发现它自身的价值。

(摘编自萧乾《知识与品味》)材料二:为了丰富通感,是不是应当尽可能广泛地接触各种艺术?要培养与扩大艺术通感能力,就要在审美活动中执着、用心。

一、现代文阅读(35分)(一)现代文阅读I(本题共5小题,17分)阅读下面的文字,完成1~5题。

材料一:博物馆和美术馆在结构转型的社会,它的一个重要目标是迈向真正的公共性。

首先,应该凸现美术馆在公共文化生活中的教育功能和知识传播功能。

欧洲的近代博物馆是收藏的产物,美国博物馆最初是仿效欧洲博物馆建立起来的,但很快便形成了自己的特色并创造了诸多"世界之最"。

不难发现,美国博物馆的这些“世界之最”都与教育有关。

而且号称“世界最大的博物馆系统”的史密森尼研究院国立博物馆群在国际互联网上统一以“edu”(教育)为后级。

美国长期以来十分重视艺术教育。

不仅如此,美国的绝大部分博物馆和美术馆都有着力量强大的教育部门。

这些教育部门除了拥有困定的有着高学历的教育及艺术史论背景的教育人员,同时还拥有庞大的义工团队。

教育部门的导赏员会针对不同的人群和对象运用不同的作品阐释及解说方法。

除此之外,博物馆和美术馆还积极与学校、社区合作,构建一些美术教育课程,提供相应的体验场所和学习空间。

事实上,当代美国博物馆不仅是收藏中心,也是文化中心、教育中心、学术中心,还是休闲中心和娱乐中心。

《华盛倾邮报》称:当代美国的博物馆已经成为"新的城市广场",举办从爵士音乐会到教育研讨会的各种活动,没有任何别的场所能像今天的博物馆一样把各种不同的人聚集到一起。

追博物馆成为华盛顿居民的一大休闲习惯,每到节假日,国会山附近的各大博物馆游人如织,热闹非凡。

CThe world is full of tea drinkers.For many,they simply enjoy the taste.But new research suggests tea might help those who drink it live longer than those who do not. Tea is known to contain helpful substances known to reduce inflammation, a condition in which a part of the body becomes red,sore and swollen because of infection or injury. Past studies have suggested several health benefits.Now, scientists say black tea may show similar benefits.Scientists from the United States National Cancer Institute carried out the study.They examined data gathered about the tea drinking behavior of almost 500,000 adults in Britain for as many as 14 years.The researchers adjusted for risks that individual may have related to health,living conditions, diet and lifestyle choices,as well as age,race and gender.The study found that high tea intake was linked to a moderate benefit: a 9 to 13 percent lower risk of death from any cause than non-tea drinkers.The scientists say the lowered risk of death held true for study subjects with heart disease.However, researchers said there was noclear finding in connection with deaths from cancer.Researchers were not sure why.But it is possible there were too few confirmed cancer deaths to measure,said Maki,who led the study.All kinds of tea-green,black,oolong,and white-are produced from the Camellia sinensis plant using different methods. Tea contains various elements,including polyphenols(多酚).Experts say polyphenols are thought to be responsible for the health benefits that have traditionally been linked to tea,especially green tea.Green tea is reported to improve mental ability, ease digestive problems and head pain,and help people with weight loss. Green tea has also been studied for possible protective effects against heart disease and cancer.The study of British tea drinkers was based on observing people's behaviors and health.This kind of methodology cannot prove cause and effect.8.What does “inflammation" underlined in Paragraph 1 refer to?A.Food intake. C.A kind of flavor.B.Security risk.D.A kind of symptom.9.How did the United States National Cancer Institute conduct the study?A. By examining data collected from tea drinkers.B. By analyzing the effects of all kinds of tea.C. By observing people of all ages across the US.D.By comparing subjects with different diseases.10. What can we learn from Paragraph 4?A.People produce tea using the same method.B.All kinds of tea can help people lose weight.C.Polyphenols are important elements good for health.D.Green tea can be used to treat heart disease and cancer.11.What is the purpose of this passage?A.To persuade people to drink more tea.B. To inform the benefits of drinking tea.C.To explain why drinking tea is popular.D.Tostress the advantages of green tea.DEarth Day is April 22.Every year,people around the world observe the day by helping to care for the environment. They carry out all kinds of activities in an effort to better the planet's health. One way to support this goal is to grow plants native to your area.This helps wildlife like birds and insects that evolved alongside native plants. For many of these animals, plant pollen is their food.Native pollinators(传粉者)often cannot recognize non-native plants as food. This means they do not collect the pollen or spread plants' seeds.Planting non-native species creates so-called "food deserts" for pollinators including bees,birds, bats,butterflies and more. Doug Tallamy is a professor of entomology at the University of Delaware. Entomology is the study of insects. He found that non-native plant species can harm the natural food chain,which can lead to a collapse of the environment. “Plant choice matters," he said. “The plants we choose to landscape our properties with should be determined by how much life can live there.”Humans depend strongly on insects. Without them, we would have no flowering plants,which would harm the food web that supports important animals.Birds,for example, depend on plants for food and spread their seeds while keeping the populations of harmful insects down. Insects support plants that provide oxygen,clean our water,capture carbon and add nutrients to the soil. That builds topsoil and prevents flooding.Without insects, the biosphere-the living parts of the Earth-would rot because of the loss of insect decomposers(分解者).Humans simply could not survive that,Tallamy said.In addition to providing food and habitat for insects and other wildlife, native plants are able to grow easily and do not require much care.That means less watering and less fertilizing.The situation is a win-win for gardeners and pollinators.12. Which of the following can benefit from native plants directly?A.Seeds.C.Humans.B.The earth.D.Birds and insects.13. Why are non-native plants harmful to the environment?A.They make it a desert.B.They pollute the topsoil.C.They damage the food chain.D.They destroy the native habitat.14. Who might be the intended readers of the passage?A.Professors.B.Gardeners.C.Scientists.D.Zoologists.15. What is the text mainly about?A The effects of native insects.B.The ways to observe Earth Day.C.The reasons for planting native species.D.The approaches to growing native plants.第二节(共5小题;每小题2分,满分10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。

江苏省扬州中学2023—2024学年度第一学期开学考试高三语文试题及答案

江苏省扬州中学2023—2024学年度第一学期开学考试高三语文一、现代文阅读(35分)(一)现代文阅读I(本题共5小题,17分)阅读下面的文字,完成1-5小题。

材料一:仅仅凭历史学家在研究工作中离不开时间这一事实,还不足以断言历史学就是时间的科学。

只有当我们认识到,不论在历史学者身上,还是在历史研究的对象、方法和手段上,时间在历史研究过程中无处不在的时候,历史学才真正称得上是时间的科学。

社会中的任何存在都是历史性的存在,这为历史研究规定了时间界限。

历史学研究人类文明的演变,文明有起源,仅就此而言,历史必然有一个时间上的开端。

同时,自有人类以来,世界上有无数的文明起起落落,英国著名历史学家汤因比列举了21个具有文明发展过程的社会,而在他那个时代,已知的原始社会的数量已经超过了650个。

因此,凡历史性的存在,都有一个时间的终点。

不论是文明,还是更加具体的历史事件和进程,在时间上都有开端和终结,在这个意义上,历史就意味着时间。

所以,历史年代学就成为历史研究中一个很重要的辅助学科,它的作用就是把历史事件根据一定的时间顺序排列起来。

目前流行的公元纪年方法,是在中世纪到近代初期逐渐地创立、完善和推广的。

有了这样一种方法,历史上所发生的事件都可以井井有条地被安放在这条可以向前和向后无限伸展的时间之线上。

而且,世界上不同地方在其曾经使用过的各种纪年法上的历史事件,都可以转换到这一线性的时序中。

这种以数字标记的线性时间,看起来客观、中性,其实不然。

虽然每个以数字表现出来的年代,原本并没有什么意义,但是,当历史学家在这些年代上开始编排历史事件的时候,这些年代就被赋予一定的意义。

例如,476年,是西罗马帝国灭亡之年,这在西方的历史上具有特殊的意义;1492年,哥伦布到达美洲,这一年被认为对近代历史发展有深远意义。

这种被赋予了重要意义的年代,在漫长的人类历史上几乎到处存在。

历史学家对历史事件的选择和倾向性,使一些数字化的时间具有非同寻常的意义。
