郑州外国语学校2024-2025学年高二上期月考语文参考答案一、现代文阅读(16分)(一)现代文阅读Ⅰ(本题共5小题,16分)1.【答案】B【解析】“会做出错误的定义或划分使推理出现瑕疵”错,材料一第一段“人类理性的活动是推演性的,而推演活动又是一种生产性的或构造性的,理性并不保证它在生产或构造或构成中不会出错,相反,它可能会做出错误的定义或划分,推理会出现瑕疵,思想会产生混乱”,可看出原文是“可能会”。

故选:B。

2.【答案】C【解析】“为了正面证明‘无理而妙’的艺术效果已经得到了学者的认可和重视”错。

引用鲁迅的话是为了从反面论证单靠逻辑和理性不能正确有效地品读鉴赏诗歌的语言,即“诗人的语言不能用常理来衡量”。

故选:C。

3.【答案】D【解析】先看“无理而妙”。

材料二第一段“语言运用的艺术,在某些情况下,又是可以突破逻辑规律的框框的,这不仅无碍于语言运用的正确,而且反而使得语言运用收到更好的艺术效果,这就是‘无理而妙’”。

A.“春风”不知离别之苦,也不能决定柳条是否发青。

李白却赋予春风以人的情感,春风不让柳条发青,怕离别之人又饱受别离的苦楚,从物的角度表现“无理而妙”。

B.不忿:恼恨、嫌恶。

思妇久盼归人,出门眺望,未见亲人,把失望迁怒于啼叫的喜鹊,表现其盼归之苦,无理而妙。

C.花不能“弄”影,此处用拟人手法,暗示有风。

一个“弄”字,生动细致地写出晚风吹拂时花影晃动之态,无理而妙。

D.是现实主义表达,没有突破思维逻辑的语言表达,不能体现“无理而妙”的艺术效果。

故选:D。

4.【答案】①材料一从逻辑内涵的角度强调逻辑是一门科学,又是一门艺术,还是一种理性精神。

②材料二从逻辑运用的角度强调语言艺术可以突破逻辑规律,达到“无理而妙”的效果,而“无理而妙”是建立在深邃的逻辑基础上的智慧和能力。

5.【答案】大前提:一个身在最高层的人是不害怕浮云挡住视线的。

小前提:我是一个身在最高层的人。

结论:我是不害怕浮云挡住视线的。

河南省郑州外国语学校2024-2025学年高一上学期第一次月考英语试卷

河南省郑州外国语学校2024-2025学年高一上学期第一次月考英语试卷一、阅读理解Amsterdam is one of the most popular travel destinations in the world, famous for its beautiful canals, top art museums, cycling culture and so on. It is the capital city of the Netherlands and often referred to as the “Venice of the North” because of its expansive system of bridges and canals. Here are some of the key points to remember as you plan your trip to Amsterdam.Must-See AttractionsMost visitors begin their Amsterdam adventure in the Old Centre, which is full of traditional architecture, shopping centers, and coffee shops. You’ll also want to check out Amsterdam’s Museum Quarter in the South District, which is great for shopping at the Albert Cuyp Market and having a picnic in the V ondelpark. The top museums to visit there are the Rijksmusuem, the Ann Frank House, and the Van Gogh Museum.If You Have TimeThere are several other unique districts in Amsterdam, and you should try to explore as many of them as time allows. The Canal Ring is a UNESCO World Heritage Site that was originally built to attract wealthy home owners and is a center for celebrity spotting and nightlife today. The Plantage area has most of the city’s museums and the botanical gardens.Money Saving Tips●Unless you really want to see the tulips(郁金香) blooming, avoid booking between mid-March and mid-May. This is when hotel and flight prices rise.●Look for accommodations in Amsterdam’s South District, where rates are generally cheaper than in the city center.●Buy train tickets at the machine instead of the counter to save a bit of money.●Instead of hiring a tour guide, hop on a canal boat. They’re inexpensive and will give youa unique point of view of the city.Check out our homepage to view price comparisons for flights, hotels, and rental cars beforeyou book.1.What can be learned about Amsterdam from this passage?A.The Van Gogh Museum lies in the South District.B.The Canal Ring is a place to attract garden lovers.C.The Old Centre is a UNESCO World Heritage Site.D.Amsterdam is called the “Venice of the North” because of its location.2.In order to save money in Amsterdam, you can ________.A.arrange a guided tour B.buy train tickets at the counterC.reserve a hotel in the South District D.book flights between mid-March andmid-May3.Where is the passage most probably taken from?A.A magazine.B.An essay.C.A report.D.A website.While famous foreign architects are invited to lead the designs of landmark buildings in China such as the new CCTV tower and the National Center for the Performing Arts, many excellent Chinese architects are making great efforts to take the center stage.Their efforts have been proven fruitful. Wang Shu, a 49-year-old Chinese architect, won the 2012 Pritzker Architecture Prize — which is often referred to as the Nobel Prize in architecture — on February 28. He is the first Chinese citizen to win this award.As head of the Architecture Department at the China Academy of Art (CAA), Wang has an office at the Xiangshan campus of the university in Hangzhou. Many buildings on the campus are his original creations. The style of the campus is quite different from that of most Chinese universities. Many visitors are amazed by the complex architectural space and different building types. The curves (曲线) of the buildings perfectly match the rise and fall of hills, forming a unique view.Wang collected more than 7 million abandoned bricks of different ages. He asked the workers to use traditional ways to make the bricks into walls, roofs and corridors. This creation attracted a lot of attention thanks to its mixture of modern and traditional Chinese elements (元素).Wang’s works show a deep understanding of modern architecture and a good knowledge oftraditions. Through such a balance, he had created a new type of Chinese architecture.Wang believes traditions should not be sealed in glass boxes at museums. “That is only evidence that traditions once existed. Many Chinese people have a misunderstanding of traditions. They think tradition means old things from the past. In fact, tradition also refers to the things that have been developing and that are still being created,” he said.The study of traditions should be combined with, practice. Otherwise, the recreation of traditions would be artificial and empty, he said.4.Wang’s winning of the prize means that Chinese architects are ________.A.following the latest world trend B.getting international recognitionC.working harder than ever before D.relying on foreign architects5.What impressed visitors to the CAA Xiangshan campus most?A.Its hilly environment.B.Its large size.C.Its unique style.D.Its diverse functions.6.What made Wang’s architectural design a success?A.The mixture of different shapes.B.The balance of East and West.C.The use of popular techniques.D.The harmony of old and new.7.What should we do about Chinese traditions according to Wang?A.Spread them to the world.B.Protect them at museums.C.Teach them in universities.D.Recreate them in practice.Bed rotting — the practice of spending long periods of time just staying under the covers with snacks, screens and other creature comforts — is gaining popularity on social media. Some Generation Z trend followers are now considering it as a form of self-care, but doctors warn too much could be “sign of depression”. Are these extended breaks really wise for one’s mental health — or could they be a cause for concern?Dr. Ryan Sultan, a professor treating many young people, called the bed rotting trend attractive. “In our culture today, with too much to do, too many expectations and too much productivity, many young individuals (个人) are feeling tired and often aren’t getting enough sleep. It’s easy to see why taking time off to lie around is attractive,” Sultan said. “In many ways, this is beneficial. It’s a chance to get away from real-life problems and clear your head beforereturning to life in a better state of mind,” he added.For the downside, however, he said a long-term need or desire for bed rotting could do harm to one’s physical health. Spending too many daytime hours in bed — awake or not — could destroy sleep schedules. Our brains are fine-tuned for sleep in darkness and alertness in light. Lying in bed half-asleep during the day will worsen sleep schedules — once that happens, it is a challenge to fix. It could also lead to blood pressure problems and obesity (肥胖).Long-term need or desire for bed rotting could also be a warning sign of depression, according to a mental health expert. Dr. Marc Siegel, professor of medicine, agreed that while some downtime can be useful in terms of de-stressing and rejuvenation (更新), too much bed rotting is bad. In addition to increasing the risk of depression, it contributes to decreased motivation (动力) as well.Instead of bed rotting, Siegel recommends regular exercise as a better form of de-stressing. While the occasional lazy day can be beneficial, too much could have the opposite effect. If it happens every day, that’s a fairly sensitive test for depression. Those who lack the motivation to get out of bed could also try calling or texting a family member for support, socializing with close friends, finding a small task to complete, or reaching out to a medical professional for help. 8.According to Dr. Ryan Sultan, why do young people like bed rotting?A.Bed rotting is a way to escape stress.B.Bed rotting helps fix sleep schedules.C.They are unwilling to socialize with friends.D.They are fond of what is popular on social media.9.What does the word “fine-tuned” underlined in Paragraph 3 probably mean?A.Quickly-started.B.Well-trained.C.Badly-needed.D.Ill-equipped. 10.What can we learn from the passage?A.Feeling down leads to decreased motivation.B.Sleeping in light can increase the risk of depression.C.Young individuals meet expectations through bed rotting.D.Being lazy from time to time can be good for individuals.11.What is the passage mainly talking about?A.Different opinions on how to become motivated.B.Main causes of the long-term need for bed rotting.C.Practical suggestions for young people to deal with stress.D.Possible problems from lying in bed for extended periods of time.Sportsmanship is the cornerstone of competitive sports, representing the principles of fair play, respect and honesty. It goes beyond winning and losing, emphasizing the importance of moral behavior, respecting each other, and fellowship.At the heart of sportsmanship lies the concept of fair play. It fosters (培养) a culture of rule-following, fair judgment, and equal opportunities for all participants. Fair play encourages athletes to compete with integrity, showing honesty and accepting the outcomes gracefully. It fosters an environment where cheating, unsportsmanlike and rude behavior are discouraged. By upholding fair play, athletes develop a sense of morality (道德) and a strong character that extends beyond the field of sports.Sportsmanship also includes respect and empathy (共情), creating an environment that encourages understanding and camaraderie. Athletes show respect for opponents, officials, and teammates, recognizing their contributions and valuing their abilities. They appreciate the various backgrounds, skills and perspectives that athletes from different teams bring to the game. Through respect and empathy, sportsmanship bridges gaps, promotes inclusivity and fosters a sense of unity among athletes and fans alike.Sportsmanship is shown by athletes who act as role models, inspiring others with their conduct on and off the field. When athletes display sportsmanship, they send a powerful message to young fans, teaching them the importance of fair play, respect and moral behavior. This positive influence extends to society as a whole, where sportsmanship can shape attitudes, values and behaviors beyond the field of sports. By upholding the principles of sportsmanship, athletes contribute to a healthier, more caring society.Sports organizations, coaches and educators play an important role in promoting sportsmanship. They should foster an environment that encourages fair play, respect and honesty. Emphasizing sportsmanship in training programs and competitions helps athletes develop a strong moral compass,empowering them to make moral choices both in sports and in life. Furthermore, fans and audience should also welcome sportsmanship, creating a positive atmosphere thatencourages fair competition and respect for all participants.Sportsmanship is the bedrock of competitive sports, emphasizing the values of fair play and respect. It improves the sporting experience, fosters unity and shapes athletes into responsible and caring individuals. By promoting sportsmanship, we can create a sporting culture where victories are celebrated but fairness, respect and the spirit of the game take center stage.12.What does the underlined word “camaraderie” mean in Paragraph 3?A.Friendship.B.Leadership.C.Contribution.D.Competition. 13.What are Paragraphs 2 and 3 mainly about?A.How sportsmanship is understood.B.Why sportsmanship is stressed.C.When sportsmanship is shaped.D.Where sportsmanship is treasured. 14.What can be learned from Paragraph 5?A.Athletes should be trained to make moral choices.B.Audience could influence athletes’ performance in sports.C.Promoting sportsmanship requires everyone’s contribution.D.Officials should take a lead in creating a positive atmosphere.15.What is the best title for this passage?A.Sportsmanship:Advantages of Doing SportsB.Sportsmanship:Spirit of Fair Play and RespectC.Showing Sportsmanship:Qualities of a Good PlayerD.Teaching Sportsmanship:Values of Honesty and CourageIn our modern economy, accelerated learning can be crucial for success. Learning faster means gaining more knowledge—quicker than others. 16 Anyone can learn from them and accelerate their learning process with the following techniques. Combine Learning Styles That Play to Your StrengthsWhen you aim to accelerate your learning, what you choose to learn should not be limited to a curriculum or classroom structure. 17 Different materials along with your learning style can accelerate or slow down your comprehension process. The best learning style is the one that makes it easier to process, or comprehend ideas, and subjects faster. Once you know your learning strengths and weaknesses, you can choose learning strategies that play to your strengths. SeekFirst to Understand The Basic Structure of The Topic You Choose18 So you need to seek first to understand the basics. In other words, you have to get to know the tree’s root, trunk, then branch out from there. Don’t start from the branches or the leaves, pursue the root and work your way to the topic. Therefore, whatever topic you choose to learn or study, just start with the basics. Give Yourself Plenty of Time in Both “Focused” And “Diffused”(分散的)ModesNormally, the human brain is not meant to stay in “focused” mode for hours at a time.19 Consequently, when your brain is active for a very long time, you’re actually blocking your access to the diffused mode — a more relaxed state.Therefore, diffused mode is just as valuable as the focused mode. So — just take breaks, let your mind wander, think about other things, and give your brain plenty of time to make better connections. 20A.You can benefit a lot from staying focused.B.Smart learners don’t have any special secrets.C.You should try to choose whatever you like best.D.Every topic or subject has a logical structure to it.E.Then you can learn better by imposing breaks on yourself.F.Long-lasting attention to a single task can block memory and recall.G.You can practically choose content from many sources, experts, and authors.二、完形填空For me, nothing is more satisfying than discovering hidden treasure in secondhand shops.21 , one person’s trash is another person’s 22 .Two years ago, I 23 a collection of old, dusty photos. I thought: if these were mine, or my family’s, I’d want someone to 24 them to me. So I made it my goal to do so for others.I’ve since visited secondhand shops weekly, and have 25 more than 50,000 of these items.

The firstitem I 27 was a tape of a family holiday that I digitized. It was a video of two parents and a son of 28 age on a trip in the 90s — the son was wearing a T-shirt with the words “Wesleyan swimming” on it. My followers asked university swimming coaches across the US if they knew the student. After just a few days, someone recognized him and we found him on social media. He couldn’t believe it and was extremely excited to get the tape.The 29 we’ve taken to find someone is four months, but I’m proud that we still 30 to do it. There are thousands of photos that have yet to be reunited. 31 social media, this project would be next to impossible. Of course, I have some 32 , including not sharing sensitive photos and removing posts if the family does not want their memories online.Nowadays, we seldom think before we take pictures with camera phones, but back then someone had made a conscious effort to keep that memory. Therefore, I want to 33 people to take care of their own family history and memorabilia (纪念品) 34 they don’t end up getting lost. Now, I’m putting together a team to 35 and return the photos.

She reached into her change purse, emptied out all the coins she had and gave them to the homeless man. Neither of them realized that this small generous act(举动) would change their lives.Sarah didn't realize that she had given Billy not only all her change but also her diamond ring that she had put in her change purse earlier until the next morning. She and her husband, Bill Krejci, rushed to see if they could find Billy. The homeless man was not only in the same place, but also immediately returned the ring. The grateful couple paid him back for his honesty by emptying out their pockets of all the money they had.Bill Krejci, a web designer, felt that he needed to do something more for this amazingly honest man. So on February 18th, he set up a special page to raise money for him. In just four days, Billy received over $85,000 and there seems to be no end yet.That is not enough. Billy is living with a person who is generous instead of living in the streets. And that’s not all thanks to the news report, he got together again with his older brother, Edwin Harris who he had been unable to find for 27 years.All the good luck is just because Billy did the right thing-returning something that did not belong to him.1.When did Sarah realize that she had also given Billy her diamond ring?A.On February 9th, 2013.

(2分)材料一提到优质制造,人们立刻想到:控制误差不超毫秒的瑞士钟表匠、仅拧各种螺丝就要学习几个月的德国工人、捏寿司都要捏成极致艺术品的日本手艺人……但对于更多的中国制造来说,我们仍然缺乏响当当的“中国名片”,如手机、冰箱甚至是前段时间引发抢购风潮的马捅盖等。

材料二在今年的两会上,李克强总理曾说:“我们要用大批的技术人才作为支撑,让享誉全球的‘中国制造’升级为‘优质制造’。

”材料三我国数千年历史中,出现过香班这样的大师级工匠,也有修造出故宫这种世界奇观建筑的工匠,这说明中华民族的基因里,的确有工匠精神。

《大国工匠》讲述的8个工匠,正是传承了中华民族的工匠精神,才蜂造了工匠的神话:鉴刻师孟剑锋为北京人PEC会议创作国礼“和美”纯银丝巾,坪工高风林为火箭焊“心脏”,柑工顾秋亮为“蛟龙号”装配载人深潜器……【品对联】(2)某校邀请大国工匠孟剑锋来校做演讲,书法社结合孟剑锋的事迹拟写了一副“宝剑锋从磨砺出,和美精自细琢来”的对联。

清晨,白露为霜,被霜私贴的衰草,似乎成了道路衰白的茸毛。

随之,狂风劲扫,树叶落尽。

我家门前有一排柿子树,落尽绿叶,如生命脱下了华丽的袍,只剩斑驳黝黑的躯干与枯枝。

②心随之苍凉。

大地呈现出贫疥,却也在此时,一种真实显露出来,一种简陋甚至丑陋的真实—这是删繁就简之后,再也无法删除的存在。

无遮无拦,也无论你的好恶。

③渐渐地,学会去适应它,进而欣赏它。

④其实,我同样欣赏生命的裸露。

当那些被隐藏的真相,像泛黄的书卷被打开,心中或许滚过一阵惊雷.随之似乎预告这个世界的箴言被揭开—总有这样先惊后喜的感觉。

⑤读过日本小说家村上春树一篇写杰克·伦敦的短文。

⑥杰克·伦救声名鹤起之后,作为日俄战争的记者来到朝鲜半岛。

当他去往一个村庄,当地的官员到他的驻地,请求他去一个万人广场,那里有无数的民众在等待他,期待一睹他的尊容。

⑦这令杰克·伦敦颇感意外,他没有想到自己的名声不只横贯了欧美,且响遍了亚洲。

然而,他更没有想到的是,民众注意力似乎不在于他对文学的真知灼见,以及他头顶上的光环。

官吏抱歉地跟他说:对不起,我们都想看您的假牙,您能否取下您的假牙让大家看一看?⑧在村民热烈的掌声中,杰克·伦敦不怒不哄,取下假牙,向民众展示自己的假牙,时间长达30分钟。

无论此刻杰克·伦敦内心有怎样的想法,事实上,他在寒风呼啸的广场上,手拿自己的假牙向民众展示了30分钟。

⑨朴实到极致的村民,自有判别虚实的独特手段,他们用“人”的角度来观察人,想见的是作为自然人的杰克·伦敦,这就得撇开星光照耀,去端详一位名人隐藏的疤痕。

⑩换上另外一个人,这样的场景,无论如何都让人难免有些尴尬。

某个领域的光环,并不能遮掩另一方面的缺憾。

真实,必然包含着这种缺憾。

杰克·伦敦是伟大的,尊享殊荣的同时,他觉得也有义务去公布不太如意的隐私。

当然,他也有更多的理由对此讳莫如深。

(11)像深秋的大地一样坦诚,才有勇气、诚恳和担当,去揭示被自己深藏的另一面。

这种真实,挤去了泡沫、娇饰、虚华,留下无可置疑的格局、本质和分量。

或许并无美感,却有价值。

(12)深秋时节,我喜欢走在旷野.看湖水澄碧,看万木萧瑟,感受自己内心的清凉。

声气内敛的大自然沉静空旷,这样的氛围,我感知到一种回归本质的精神贯穿万物,取代繁华:一种真实—无遮无拦,不计荣辱。

(3分)(二)阅读下文,完成13-16题。

(共12分)唯有淡定才能强大无比①生活在快节奏、高频率的现代社会,我们都有一个感觉:累。

我们需要承受重重压力:学业的压力,工作的压力、生活的压力等等。

所以,时下有一句流行的话:累并痛苦着。

我们为什么会觉得痛苦,感到活得很累?因为我们有太多的欲求,太多的愿望,太多的梦想,什么都想得到,什么都不想放弃,什么都要拥有,什么都不愿舍去。

患得患失,贪得无厌,当然就很累,当然就痛苦。

②美国现代成人教育之父卡耐基在《淡定—做内心强大的自己》一书中告诉我们:唯有淡定,我们才能强大无比;唯有淡定,我们才能静观花开花落,笑看云卷云舒;唯有淡定,我们才能尽情享受生活的踢予,获得人生的幸福。

③什么是淡定?作者告诉我们,淡定就是对名利荣辱的淡然,就是对爱恨情仇的超脱,是对世态炎凉的看破。

它能让浮躁的人们学会放下,告诉人们一切顺其自然便能宁静致远;它让人们在淡定中滋养心灵,在智慧中升华人生。

心怀淡定之心的人,必将是最坦然、最和平、最洒脱的人。

④古往今来,凡是有所成就者无不具有“宠辱不惊”的宝贵品格。

莫言在获得诺贝尔文学奖后.各种评论纷至杏来。

莫言超然地说:“起初,我还以为大家争议的对象是我,渐渐地,我感到这个被争议的对象,是一个与我毫不相关的人。

我如同一个看戏的人,看着众人表演,我看到那个得奖的人身上落满了花朵,也被掷上了石块.泼上了污水,我生怕他被打垮,但他微笑着从花朵和石块中钻出来,擦干净身上的脏水,坦然地站在一边。

”这就是淡定,处世的智慧。

⑤怎样才能保持淡定,做有智慧的人呢?有智慧的人能够正确面对宠辱得失,无论世间如何变化,无论人生经历怎样的风雨,内心总能风平浪静。

有智慧的人,是懂得生活辫证法的人,知道有所得必有所失,拥有的同时也会失去,必须学会放弃。

有智慧的人,是自信的人,相信“天生我材必有用”,能够自己掌拉自己,不会被别人的议论所左右。

有智慧的人,懂得调节自己的心情,保持良好的心态,不会因打翻牛奶而影响好心情。

有智慧的人,也是懂得宽容的人,既宽容自己,宽容失致,也宽容别人,宽容错误,深知原惊别人就是解脱自己。

⑥世间一切烦恼都是自找的。

一个人能否成功,并不取决于别人怎样看待自己,而在于自己怎样看待自己。

无论面对怎样的生活景况,无论生活带给我们什么样的痛苦,必须始终记住:影响我们生活的不是处晚,不是身份,而是我们的心垅。

一定要让自己的心情保持永远的杨快。

“淡定”被手为洗涤内心污秽,解除心灵束缚,自我救助,还原幸福的心灵修行宝典。

⑦总之,淡定,是一种生活态度,一种思想境界,一种豁达人生一种成熟心态。

唯有内心淡定,我们才能强大无比,让我们学会淡定吧,珍惜人生,享受快乐,追求幸福。

13.请分析第①段在文中的作用。

(3分)14.为什么在第④段写莫言获诺贝尔奖后说的话?(3分)15.成为有智慈的人,需要做到哪几方面?请根据文意分点概括。

(4分)16.请你将本文的论证思路补充完整。

(2分)以社会现象引出有关淡定的论点—( A )-( B )—总结全文,内心淡定才能强大。

三、古诗文阅读(14分)(一)阅读下面两个语段.完成17一20题。

(共II 分)【甲】环滁皆山也。

其西南诸峰,林壑尤美,望之漪然而深秀者,琅琊也。

山行六七里,渐闻水声潺潺而泻出于两峰之间者,酿泉也。

峰回路转,有亭翼然临于泉上者,醉翁亭也。
