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:《古诗十九首》是五言古诗中最早期、最成熟的代表作品。
它在谋篇、遣词、表情、达意等各方面,都对我国旧诗产生了极深远的影响。
然而奇怪的是,如此杰出、如此重要的一组诗,我们大家却始终不知道谁是它们的作者!刘勰的《文心雕龙·明诗篇》说:"至成帝品录,三百余篇,朝章国采,亦云周备,而词人遗翰,莫见五言。
”又说:"古诗佳丽,或称枚叔,其《孤竹》一篇,则傅毅之词,比采而推,两汉之作乎"枚叔即墨枚乘,是西汉景帝时的人,傅毅是东汉明帝、章帝时的人。
大家知道,景帝的时代比成帝早得多,如果景帝时代的枚乘写出了这么多这么好的五言诗,那么成帝时代编选作品时怎么会不选这些诗呢这已经是一个问题。
但认为这些诗里有枚乘作品的,还有徐陵。
他编的《玉台新咏》中,收了九首枚乘的诗,其中有八首在《古诗十九首》之内。
然而,刘勰、徐陵和昭明太子萧统都是南北朝时期的人,以《昭明文选》《文心雕龙》和《玉台新咏》这三部书相比较,《玉台新咏》成书年代最晚。
《昭明文选》选了这一组诗,标为"古诗十九首”,说明萧统当时不知道它们的作者;《文心雕龙》说"古诗佳丽,或称枚叔”,说明刘勰也不敢确指枚乘就是这些诗的作者;那么徐比他们的年代稍晚,怎么反而能够确定枚乘是它们的作者呢其实,比他们年代更早的,还有陆机。

材料一:卓越的演化生物学家西奥多修斯·多布赞斯基写道:“若无演化之光,生物学的一切都无意义。
”严肃的、可重复的科学研究已经得出结论,音乐的声响实在和植物没有关系,而且这从演化的角度来看也是有意义的。
在植物的演化史长河中,只有200年历史的古典音乐和只有50年历史的摇滚乐不过是一点小浪花。
不过,是否至少在理论上存在什么有利的声音,值得植物去回应呢?特拉维夫大学的理论生物学家莉拉赫·哈达尼教授用数学模型研究演化。
她认为植物的确能对声音产生反应,但我们必须设计正确的实验来检测这一行为。
按她的设想,我们应该设计一种研究,用已知自然界存在的声音去影响一个特定的植物生理过程。
如果科学家想要研究植物对声波的反应,那么他们需要考虑,能够让植物听到并产生演化优势的那些与生理相关的声音究竟是什么。
这样的声音可能要么能提供有关水分之类资源所在位置的线索,要么能提醒植物即将发生的有益或有害的生物相互作用——比如与传粉者或食草动物之间的相互作用。
直到最近几年,才有人尝试去识别这样的反应。
莫尼卡·加利亚诺是西澳大利亚大学的一位研究副教授;斯泰法诺·曼库索教授则是佛罗伦萨大学植物神经生物学国际实验室主任。
她们与其同事一起尝试为她们起名为“植物生物声学”的研究领域建立理论和实践基础。
在2012年发表的一项研究中,她们报道,如果声波的波长类似于水传播的振动波长,则根尖会明显向水源弯曲。
这似乎暗示,根可以通过聆听水流来搜寻新的水源!事实上,加利亚诺的团队近来又表明,豌豆的根可以朝向水流方向生长。
这些研究结果有助于解释城市工程师几十年前就知道的现象:树木的根常会包围地下的供水管和污水管,甚至侵入其中,导致大量设备损坏和财产损失。

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。
材料一:①游侠是中国历史文化发展的产物,它产生于民间,兴于先秦两汉。
司马迁的《史记·游侠列传》中说:“今游侠,其行不轨于正义,然其言必信,其行必果,已诺必诚,不爱其躯,赴士之厄困。
既已存亡死生矣,而不矜其能,羞伐其德,盖亦有足多者焉。
”游侠形象出现在文人诗歌中,始于汉魏乐府。
郭茂倩《乐府诗集》卷66在《结客少年行》的题解中说:“《后汉书》曰:‘祭遵尝为吏部所侵,结客杀人。
’曹植《结客篇》:‘结客少年场,报洛北邙。
’《乐府题解》曰:‘《结客少年场行》,言轻生重义,慷慨以立功名也。
’……按结客少年行,言少年结任使之客。
为游乐之场,终而无成。
故作此曲也。
”自汉魏至隋,以游侠为题材的诗歌,虽有所出现,但数量有限,未成规模。
到唐初,经卢照邻、骆宾王、杨炯等人的推进,大有发展,至盛唐蔚然成风。
据《开元天宝遗事》载:“长安侠少,每至春时结党联朋,各置矮马,饰以鞯金络,并绕以花树下往来,使仆人执酒而随之,遇好囿则驻马而饮。
”王维的《少年行》“新丰美酒斗十千,咸阳游侠多少年。
相逢意气为君饮,系马高楼垂柳边”的诗句,是这一状况的最好明证。
②游侠诗在盛唐达到高峰有其特定的原因,经济的繁荣、政治的稳定、政府制度上的鼓励以及建功立业的社会氛围是游侠诗产生的前提和文化背景。
游侠的形象从表面上看似乎带有道家的“独往高蹈”“狂放不羁”的出世风格,实质上,这种道家风格的背后是儒家积极入世、建立功业的渴望。

Or loads of other horrible things that if you survive, you’re left scarred in one way or another.For many years I worked in a specialist NHS clinic for people with eating disorders, which are greatly misunderstood and connected with vanity (虚荣) when instead it’s usually about control or even profound trauma (精神创伤). Eating disorders have the highest mortality of any mental illness, with one in five of those with an eating disorder dying from it. Treatment for it is long, tough and tiring. So, it’s fair to say it’s not something to be taken lightly.Yet I was often surprised by how many patients-patients with all sorts of other conditions too, from depression to cancer -would tell me how the experience had changed them for the better after receiving treatment. It’s not so much that what doesn’t kill you makes you stronger; more, it might make you more understanding of yourself and more sensitive to the battles and struggles of others. It can also give people a sense of determination and perseverance they never had before.I had one patient who was an addict and alcoholic besides suffering eating disorder. She was frequently rushed into hospital and was sometimes at a real risk of dying. However, after years of hard work, she stopped drinking, stopped using drugs and her eating disorder improved. She got back into work and started doing several courses to get promoted. Actually, she had gone through numerous intense and exhausting interviews before landing a job, but she said whenever she felt she couldn’t handle it or doubted her capabilities, she reminded herself that nothing would ever be worse or harder than what she had already gone through. She managed to make the mostof her life and turn her life around.19.What does the author think of the old mantra?A.Always applicable.B.Totally absurd.C.Partially right.D.Quite misleading.20.What does the underlined word in paragraph 2 possibly mean?A.The number of deaths.B.The possibility of being cured.C.The rate of getting mentally hurt.D.The chance of having mental illness.21.How does the experience influence patients according to paragraph 3?A.It leads to a changeable attitude.B.It makes no noticeable difference.C.It builds up their physical strength.D.It fosters self-awareness and sympathy.22.What can we learn about the patient mentioned in the last paragraph?A.She continued harmful habits.B.She relied only on medication.C.She always believed in herself.D.She became stronger and tougher.Many economists predict 2024 will be the time shoppers tighten their belts. That doesn’t mean people will stop spending, say retail(零售) analysts. But it will change what they choose to buy. With a slowing job market global consumers are likely to move away from high-priced purchases and focus instead on smaller, less expensive treats.The economic uncertainty means that consumers are becoming more discriminating about their purchases, says Ethan Chernofsky, senior vice president of marketing at intelligence platform Placer.ai. “There are the things we decide are necessary, and then there’s another category of things that aren’t necessary but that we consider affordable luxuries, ” he says. This desire for these “affordable luxuries” is common in difficult economic times. Some economists refer to the phenomenon as the “lipstick index”. When economic times are tough people tend to, people tend to choose affordable splurges (挥霍)-like cosmetics (化妆品) to treat themselves. Commentators speculate that these purchases are driven by their relative affordability and the consumer’s desirefor escapism. Sales of lipsticks, perfumes and other cosmetics are indeed up.Over six months. We asked consumers in 23 countries if they were making purchases to treat themselves. We created a database with nearly 150,000 consumer descriptions of their splurge purchases, including what they bought, how much they spent and why they bought it. Efforts revealed that consumers are treating themselves much more than expected. Analysts at Deloitte say consumers will spend on little luxuries like specialty coffees and snacks as well. Additionally, stressed-out shoppers are prioritizing small splurge purchases for wellness and personal care.As retailers see shoppers turning to little luxuries, many companies orient their marketing efforts around “occasions” and “life events”. The “splurge occasion” could open up the opportunity for retailers to capture new sales from consumers buying to treat themselves. Target has staked a flag in what they refer to as “affordable joy”. For example, focusing marketing efforts on a scarf’s fashionable attributes may be tempting. Still, under US$100, it may be more effective to lure customers by also tying in the practicality of the purchase.Ethan says not every shopper will shift their spending to little luxuries-but even those who are still longing for the “must-haves” of social media will also look to get a deal. They want the feeling of purchasing lower-priced affordable treats. To get these goods, shoppers are likely to tap into the re-sale market for designer items at a more reasonable price. They want things that make them feel good about themselves-they just want to do it without breaking the bank.23.What can affordable luxuries be?A.Moderate-priced designer items.B.High-end technological products.C.Reasonably-cost daily necessities.D.Economically-preferred large deals.24.What is paragraph 4 mainly about?A.The competition stores face.B.The strategies retailers adopt.C.The products consumers buy.D.The pleasure businesses offer.25.What do most shoppers seek according to Ethan?A.World-luxry brands.B.Second-hand bargains.C.Social-media purchases.D.Budget-friendly pleasures.26.Which of the following is the best title for the text?A.Lipstick Index: Where Does It Lead UsB.Must-have Treats: A Future Spending TrendC.Little Luxuries: A Driving Force Behind ConsumptionD.Affordable Joy: Will We Fall Into The TrapSuggestion that people should aim for dietary diversity by trying to eat a variety of foods has been a basic public health recommendation for decades in the United States everywhere. Now, however, experts are warning that aiming for a diverse diet may actually lead to just eating more calories, and, thus, to obesity. One issue is that people may not interpret “variety” the way nutritionists intend. This problem is highlighted by new research conducted by the American Heart Association. Researchers reviewed all the evidence published related to dietary diversity and saw a correlation between dietary diversity and a greater intake of both healthy and unhealthy foods. This had implications for obesity, as researchers found a greater prevalence of obesity amongst people with a greater dietary diversity.One author of the new study explained that their findings contradict standard dietary advice, as most dietary guidelines around the world include a statement of eating a variety of foods. But this advice does not seem to be supported by science, possibly because there is little agreement about the meaning of “dietary diversity,” which is not clearly and consistently defined. Some experts measure dietary diversity by counting the number of food groups eaten, while others look at the distribution of calories across individual foods, and still others measure how different the foods eaten are from each other.Although the findings of this new study contradict standard dietary advice, they do not come as a surprise to all of the researchers involved. Dr. Rao, one of the study authors, noted that, after 20 years of experience in the field of obesity, he has observed that people who have a regimented lifestyle and diet tend to be thinner and healthier than people with a wide variety of consumption. This anecdotal evidence matches the conclusions of the study, which found no evidence that dietary diversity promotes healthy body weight or optimal eating patterns, andlimited evidence shows that eating a variety of foods is actually associated with consuming more calories, poor eating patterns and weight gain. Further, there is some evidence that a greater variety of food options in a single meal may delay people’s feeling of fullness and actually increase how much they eat.Based on their findings, the researchers endorse a diet consisting of a limited number of healthy foods such as vegetables, fruits, grains, and poultry. They also recommend that people simultaneously endeavor to restrict consumption of sweets, sugar and red meat. The researchers stress, however, that their dietary recommendations do not imply dietary diversity is never positive, and that, in the past, diversity in diets of whole, unprocessed food may have actually been very beneficial.27.What did the new research by the American Heart Association find?A.Big eaters are more likely to become overweight.B.People seeking dietary diversity tend to eat more.C.Dietary diversity is positively related to good health.D.Unhealthy food makes people gain weight more easily.28.What could help to explain the contradiction between the new findings and the common public health recommendation?A.There is little consensus on the definition of dietary diversity.B.The methods researchers use to measure nutrition vary greatly.C.Conventional wisdom about diet is seldom supported by science.D.Most dietary guidelines around the world contradict one another.29.What did the doctor find after 20 years of research on a big city?A.Dietary diversity promote healthy body weight.B.Eating patterns and weight gain go hand in hand.C.Diversified food intake may not contribute to health.D.There is no clear definition of optional eating patterns.30.What does the passage say about people who eat a great variety of food?A.They tend to consume more sweets, sugar and red meat.B.They don’t feel they have had enough until they overeat.C.They don’t have any problems getting sufficient nutrition.D.They are more likely to eat foods beneficial to their health.Happier Babies Have an EdgeParents and teachers want children to grow up to be happy and successful.31 A wide range of research, however, indicates happiness brings success in adults, and achievements do not always make adults happier.Recently in new study, John K. Coffey II, assistant professor of psychology at Sewanee, the University of the South, found that happiness during infancy (婴儿期) predicted childhood IQ and adult educational success.In his 29-year study, Coffey used the Fullerton Longitudinal Study (FLS). In 1978 the FLS research team recruited 130 parents with babies for a study that now has run for more than 30 years. 32 When each baby was 18 months old, one parent reported how often his or her baby expressed positive and negative emotions and researchers measured the infant’s IQ. When babies were children (ages 6 to 8), they completed IQ tests. When babies had grown into 29-year-old adults, they reported how many years of education they had completed and their life satisfaction.As expected, Coffey found that regardless of intelligence during infancy or parents’ wealth, happier babies were more likely to graduate from high school and college. 33 It suggests that happier babies learn more between infancy and childhood.34 Parents wishing to help their children enjoy greater happiness can focus on small changes they can make in their day-to-day lives to create more positive moments. Parents do not need to aim for intense experiences or “best day ever” for their children. Although peak experiences can be fun, they also tend to be tiring for both children and their parents, which can lead to anxiety and conflict.Currently, Coffey and other researchers are exploring when and why some children are happier than others or whether we can increase it. Happiness during infancy and childhood is predicted by relationships with caregivers and teachers or by learning new skills. Inexpensive and easy-to-do activities like practising acts of kindness or appreciation can boost happiness. 35 A.We often think that achieving success will ultimately make us happy.B.We can use these activities to help children grow into happy and successful adults.C.To test his theory, Coffey looked at how intensely children’s emotions are experienced. D.These happy babies aren’t just growing up to be successful, but they are also happy adults. E.Further, happier babies had more growth in their IQ scores between infancy and childhood. F.Another important clarification is that happiness is about how often emotions are experienced. G.Early on, parents reported on their background, for instance, education level and employment.三、完形填空My son had just gotten his driving license.

The weather was awful, for it was pouring with rain, and I would’ve loved to buy umbrellas for people. I decided to think of free or really cheap ways to make people smile. I knew I’d also have to deal with my shyness, or just create acts of kindness, but it was a challenge that I was willing to accept!When I was on the bus, the seat I sat on next to the window was wet; somehow the rain had gotten in. I left a note on the seat, with the Smile Card, saying, “This seat is wet: sit with caution (谨慎) !” Later, while waiting at the road crossing, I held my card over the woman standing in front of me. She didn’t notice but obviously those extra moments of dryness would help!After the interview, I’d devised a few more ways to create smiles. I checked my purse for change and put 50 pence and a Smile Card on top of a child’s automatic ride. I allowed an elderly gentleman to go in front of me as he was having trouble standing. At this point, I was really beginning to accept my day of kindness!Before getting on the bus home. I had one more idea: I went and bought a small bag of chocolates and attached a Smile Card. When I got back to my street, I left the sweets and the Smile Card at a neighbour’s door. This neighbour had taken in a parcel (包裹) for me last week, so he deserved a treat.After all this, my day of giving wasn’t yet over! I was so pleased that I managed to do all these little things for others today.

The changing climate will break historical rainfall patterns, but which of these, temperature or rainfall, will have the most impact on a species, like rhinos (犀牛) ?“Generally speaking, most, if not all, species will. in one way or another, be affected by the changing climate,” says lead author Hlelowenkhosi S. Mamba, who completed this research. It is therefore important to catch tendency (趋势) and model futures for some of the world’s weakest species. It can help prepare to reduce climate change’s effects, hence reducing global biodiversity losses.To understand how our changing climate will affect rhino populations, Mamba and Timothy Randhir, professor of environmental protection, focused their efforts on the five large national parks that are home to most of the rhinos.Mamba and Randhir then modeled two scenes for each of the parks: the IPCC’s high-emissions (排放) scenes and a more moderate (适度的) emissions scenes. They projected temperature and rainfall for each of the scenes out to 2055 and 2085 to arrive at a possibility that each park would remain suitable for the rhinos.Nearly every park will become increasingly drier as emissions increase. This is all very bad news for the rhinos, because the team also found that, though the change in rainfall will not bemost suitable for the rhinos, the changes in temperature are greater than what the species can bear.“The temperature conditions in all study parks will become increasingly unsuitable for the species. And under the high-emissions scenes, the possibility of occurrence of the species falls to zero by 2085,” the authors write.But to be forewarned is to be prepared in advance. “We propose that park managers think now about increasing water supplies, tree cover, watching for stress and planning to allow rhinos to move from one place to another place as the world warms,” says Randhir.8.Why does the author ask a question in Paragraph 1?A.To show an evidence.B.To stress the main idea.C.To lead in the topic.D.To offer some background.9.What does the second paragraph mainly focus on?A.The means of the research.B.The content of the research.C.The process of the research.D.The significance of the research. 10.What can we know about the research from the text?A.Changes in rainfall have a greater effect on rhinos.B.Each park will have no rhinos in 2055.C.Changes in temperature affect rhinos more.D.Each park will be warmer by 4. 5℃ in 2085.11.What does Randhir mean in the last paragraph?A.Rhinos are better suited to natural growth.B.Rhinos are in great danger in the five parks.C.Park managers should plan to protect rhinos.D.Park managers must pay more attention to nature.Researchers have developed a new soft robot design that conducts itself with three behaviours at the same time: rolling (翻滚) forward. turning like a record and following a path that goes around a central point. The equipment, which operates without human or computer control, holds promise for developing soft robots that can be used to AA-head and map unknown environments.The new soft robots are called twisted ring-bots (扭曲环机器人) . They are made ofsomething like the ribbon (缎带) and then joined together at the end to form a ring.When the robots are placed on a surface that is at least 55 degrees Celsius, which is hotter than the surrounding air, one part of the ribbon touching the surface becomes smaller, while one part in the air does not. This induces a rolling movement: the warmer the surface, the faster the robot rolls. “The ribbon rolls on its horizontal axis (横轴) , giving the ring forward strength,” says Jie Yin, a professor of mechanical and aerospace engineering.The twisted ring-bot also turns along its central axis. And as the twisted ring-bot moves forward it travels in a path around a central point, basically moving in a large circle. However, if the twisted ring-bot meets a boundary- like the wall of a box-it will travel along the boundary.The twisted ring-bots are examples of equipment whose behaviour is governed by physical intelligence, meaning their actions are determined by their structural design and the materials they are made of, rather than being directed by a computer or human.“Soft robotics is still a relatively new field.” Yin says. “Finding new ways to control the movement of soft robots in a repeatable and engineered way moves the field forward. And advancing our understanding of what is possible is exciting.”12.What makes the robot roll faster and faster?A.The ribbon.B.The central axis.C.The shape and material.D.The higher surface temperature.13.How does the author introduce the new soft robots?A.By explaining the robot’s working ways.B.By quoting experts’ opinions.C.By making some comparisons.D.By offering reasons and results.14.What is Yin’s attitude towards twisted ring-bots?A.Unclear.B.Favourable.C.Negative.D.Doubtful. 15.What is the best title for the text?A.The New Soft Robots B.Ribbons and Their RollingC.Three Creative Movements D.Twisted Rings and the Axis4 Reasons Why Wild Animals Are So ImportantAs we know, the earth gives us food, medicines and materials, often through wild animals. These wild animals are important to our existence. Sadly, they are becoming extinct at an alarmingrate. We need to change this loss of nature and create a future where wildlife and people thrive (蓬勃发展) again. 16 Here are some reasons why wild animals are so important to the world at large.Wild animals keep balance in ecosystems.17 If any part is threatened or becomes extinct, this has a knock-on effect on the whole ecosystem. sending shock waves through the environment. For ecosystems to survive and perhaps even thrive, we must protect all of our wildlife.Diversity (多样性) means healthier ecosystems and healthier wild animals.When there is a wildlife issue, you’ll often hear the term biodiversity, which refers to the number of species in an ecosystem. 18 Why do we consider this important? A wide variety of animals means greater productivity and better health. If there are fewer animal species, a disease that affects any species spreads faster and more effectively.19All of the food that we eat comes from an animal or plant. Living without various food sources causes our nutrition (营养) to suffer. Protecting wildlife and its natural habitats strengthens food safety for humans around the world.Wildlife helps medical research.Wild animals have helped us find important medicines that help with many diseases. 20 Many medical systems like Chinese traditional medicines still rely on herbs and spices, but even Western medicine have made great progress with wildlife research.A.All living things are interconnected.B.Healthy ecosystems mean a lot of diversity.C.Or we will lose these animals to future generations.D.People worldwide depend on wildlife for their snack.E.Wildlife provides important nutrients for the human race.F.The human race has always turned to nature for medicine.G.We should notice the influence caused by wildlife on culture.二、完形填空The caring employees at a Costco store near Cleveland, Ohio, are being honoured as heroes. It was because of their quick thinking and being sympathy (同情) , which 21 saved the life of a fellow co-worker.The story 22 one morning when the employee failed to show up for his scheduled shift (换班) at 5 a. m. 23 for his colleague, the manager, Jesse Orsborn, decided to 24 and make sure everything was okay.“In situations where someone might oversleep for the early shift, we usually give them a 25 wake-up call, checking if they’re on their way.

湖北省武汉武昌区市2023-2024年学年5月月考语文试题【附答案】
湖北省武汉武昌区市2024年五月九年级语文训练一Ⅰ阅读(共55分)一、(10分)阅读下面的实用类文本,完成下面小题。
虚构的力量①虚构对历史或新闻来说,可能是一场灾难,但对文学却是化腐朽为神奇的灵丹妙药。
②文学通过虚构重组现实,获得比现实本身更具吸引力的艺术世界,引发读者对现实的新感受。
作家可以放纵自己的想象,虚构一段妙趣横生的际遇,虚构一片清风徐来、暗香浮动的诗意……文学作品中的一切只是零星地散见于社会生活的各个角落,是作家通过虚构加以重组,才把它们解放出来,组合成一个富有魅力的新整体。
“君问归期未有期,巴山夜雨涨秋池。
何当共剪西窗烛,却话巴山夜雨时”,李商隐用虚构把现在、过去、未来巧妙地组合在一起,获得了动人心魄的美丽意境。
鲁迅小说中的人物往往嘴在浙江,脸在北京,衣服在山西,都是“拼凑”起来的角色,但鲁迅的“拼凑”却犹如放大镜,照出了国人固有的阿Q式的自我安慰、闰土式的麻木。
显然,文学对现实的反映绝对不是照相机式的,而是通过作家的虚构,通过对现实的增删改造,创作了富有魅力的文学作品,带给读者审美愉悦的同时,让他们对现实有了更深入的理解或更新鲜的认识。
③按照弗洛伊德的说法,作品就是作家的白日梦。
戏剧中的理想人物,诗词中的良辰美景,小说中的乌托邦,无不如此。
经典文学作品中,陶渊明在战乱频繁的东晋,虚构了《桃花源记》。
通俗小说中,武侠小说的快意恩仇,言情小说的才子佳人,网络文学的“穿越”“玄幻”小说,其内在构成无不是满足虚构的白日梦。
在这些作品中,善恶有报,两情长久,弱者变身英雄,常人化为贵族。
创造、阅读这样的作品,作家和读者都可以编织白日梦,获得暂时性的情感宣泄和欲望满足。
④文学虚构未知的世界,开启人类对未知或未来的想象,这一点在科幻小说中尤为突出。
19世纪的科幻小说《海底两万里》中,尼莫不用离开他豪华舒适的潜艇,就可以在海洋深处展开奇异旅行,他需要的一切都能利用海洋资源制作。
《水晶蛋》里的普通店主通过一枚水晶蛋获得了不可思议的视力,他能看到火星上的房屋和飞来飞去的火星人。
