2024~2025学年度上期高2025届10月阶段性测试语文试题考试时间:150分钟满分:150分一、现代文阅读(33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:陈国栋同志的报告是一个重要文件。

请各大区区长主持讨论,细致地讨论,讨论两次至三次。

我基本上同意这个文件所述的意见。

但觉:(一)假定今年年成比去年确实好的情况之下,征购一千一百亿斤,力争办到,这是变被动为主动的第一着。

今年年成如果在秋收以后确实较去年好,确实证明无妄的时候,为什么不能征购到这个数目字呢?(二)下年度销售计划,我感觉不但一千另二十亿斤,是太多了,这个文件上调整为八百五十五亿斤,似乎也略为多了一点。

是否可以调整为八百亿斤,或者八百一十、二十亿呢?告诉农民,恢复糠菜半年粮,可不可以呢?苦一年、两年、三年,就翻过身来了。

多储备,少食用,以人定量,粮食归户……忙时多吃,闲时少吃,有稀有干,粮菜混吃,仍然可以吃饱吃好,可不可以这样做呢?(三)多产粮,是上策。

田头地角,零星土地,谁种谁收,不征不购,主要为了解决饲料,部分为了人用。

恢复私人菜园,一定要酌给自留地。

凡此种种,可以多收。

既已多收,可以多吃(例如菜)。

(四)好好地精细地安排过日子。

是否可以按照一九五七年的实际产量安排过日子呢?一九五七年的日子不是过得还不错吗?这样做,农民的粮食储备就可以增得较多了。

手里有粮,心里不慌,脚踏实地,喜气洋洋。

……以上几点意见,只供同志们此次讨论的参考,切勿下传。

不对之处,准备修改。

(摘自毛泽东《粮食问题》)【注】材料一是毛泽东于一九五九年七月五日为印发粮食部副部长陈国栋关于一九五九至一九六零年度粮食分配和粮食收支计划调整意见的报告写的批语,题目是毛泽东拟的。

此前毛泽东曾批示:“按人定量,忙时多吃,闲时少吃,忙时吃干,闲时半干半稀,杂以番薯、青菜、萝卜、瓜豆、芋头之类。

”材料二:一个国家唯有立足粮食基本自给,才能掌握粮食安全的主动权,才能保障国运民生。

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,完成下面小题。

对素食者和肠胃疾病患者来说,藜麦的发现是一个奇迹。

藜麦不含麸质,富含镁和铁,比其他种子含有更多的蛋白质,包括人体无法独自生成的必需的氨基酸。

美国宇航局宣布,藜麦是地球上营养最均衡的食物之一,是宇航员的理想之选。

产于安第斯山的藜麦有一个令西方消费者神往的传说:印加人非常重视藜麦,认为它是神圣的,并且称之为“万谷之母”。

不过,藜麦的爱好者却通过媒体发现了一个令人不安的事实。

从2006年到2013年,玻利维亚和秘鲁的藜麦价格上涨了两倍。

2011年,《独立报》称,玻利维亚的藜麦消费量“5年间下降了34%,当地家庭已经吃不起这种主食了,它已经变成了奢侈品”。

《纽约时报》援引研究报告称,藜麦种植区的儿童营养不良率正在上升。

2013年,《卫报》用煽动性标题提升了人们对这个问题的关注度:“素食者的肚子能装下藜麦令人反胃的事实吗?”该报称,贫穷的玻利维亚人和秘鲁人正在食用更加便宜的“进口垃圾食品”。

《独立报》2013年一篇报道的标题是“藜麦:对你有利--对玻利维亚人有害”。

这些消息传遍了全球,在健康饮食者之中引发了一场良心危机。

在社交媒体、素食博客和健康饮食论坛上,人们开始询问食用藜麦是否合适。

这种说法看似可信,被许多人认可,但是经济学家马克·贝勒马尔等人对此则持保留意见。

毕竟,藜麦贸易使大量外国资金涌入玻利维亚和秘鲁,其中许多资金进入了南美最贫穷的地区。

几位经济学家跟踪了秘鲁家庭支出的调查数据,将种植且食用藜麦的家庭、食用但不种植藜麦的家庭和从不接触藜麦的家庭划分为三个小组。

他们发现,从2004年到2013年,三个小组的生活水平都上升了,其中藜麦种植户家庭支出的增长速度是最快的。

My mum began the painful yet necessary task of sorting through her belongings.“Is there anything you want from grandma’s flat?” Mum texted me.“Her aloe (芦荟), please.” I required zero thinking time.Sometime around 1975, Grandma, always believing good things would happen in the future, received this plant as a gift, which she appreciated and placed in her doorway. It came from thelocal butcher. Five years later, my mum married the butcher’s son and had me. Grandma revealed to me this particular plant was a living relationship between the two families. And so was I.Recently, whenever we visited Grandma’s flat, I attempted to fix this concept in my children’s minds. “That was a gift your great-grandma bought your other great-grandma! It’s older than me!” Then my kids would nod and ask Grandma for a sweet.Numerous times, Grandma gave me cuttings or clippings of the plant, hoping I might raise my own and continue the legend. Yet, every time, my new branch died with my awful gardening skills. But that didn’t used to matter, because I could turn to Grandma, who would wait and accept my disturbance without becoming upset. Then I got another clipping and tried again. But now I can’t. So, I decided that the plant will go and live with Ann, my mother-in-law, who is a genius with a greenhouse.The plan is for Ann to keep hold of the original plant. In time, she can teach me how to deal with its cuttings properly, and then maybe one day I can settle the plant in my place.In the meantime, Ann will allocate (分配) clippings among my relatives, as Grandma used to do. My wife’s two sisters, for example, are both better at tending plants than I am, so it is quite imaginable that they, too, will offer cuttings of the plant to their partners, spreading this loving plant across my entire extended family.20.Why did the author want his grandma’s aloe?A.He wanted to pass it down to others.B.He showed a preference for gardening.C.He had a pleasant memory of the plant.D.He received it as a gift from his grandma. 21.Which of the following best describes the author’s grandma?A.Optimistic and patient.B.Generous and helpful.C.Honest and fashionable.D.Humorous and skillful.22.The author took the aloe to his mother-in-law toA.display his skills in gardening B.have the plant better cared forC.announce his grandma’s death D.protect the plant from dying out23.What may be the best title for the text?A.Aloe: my family bond B.Aloe: a mysterious plantC.Grandma: my life coach D.Grandma: a lovely gardenerLanguages have been coming and going for thousands of years, but in recent times there has been less coming and a lot more going. When the world was still populated by hunter-gatherers, small, tightly knit(联系) groups developed their own patterns of speech independent of each other. Some language experts believe that 10,000 years ago, when the world had just five to ten million people, they spoke perhaps 12,000 languages between them.Soon afterwards, many of those people started settling down to become farmers, and their languages too became more settled and fewer in number. In recent centuries, trade, industrialization, the development of the nation-state and the spread of universal compulsory education, especially globalisation and better communications in the past few decades, all have caused many languages to disappear, and dominant languages such as English, Spanish and Chinese are increasingly taking over.At present, the world has about 6,800 languages. The distribution of these languages is hugely uneven. The general rule is that mild zones have relatively few languages. Often spoken by many people while hot, wet zones have lots, often spoken by small numbers. Europe has only around 200 Languages: the Americas about 1,000, Africa 2,400; and Asia and the Pacific perhaps 3,200, of which Papua New Guinea alone accounts for well over 800. The median number(中位数) of speakers is a mere 6,000, which means that half the worlds languages are spoken by fewer people than that.Already well over 400 of the total of 6,800 languages are close to extinction(消亡), with only a few elderly speakers left. Pick, at random, Busuu in Cameroon (eight remaining speakers), Chiapaneco in Mexico(150). Lipan Apache in the United States(two or three) or Wadjigu in Australia (one, with a question-mark): none of these seems to have much chance of survival. 24.What can we infer about languages in hunter-gatherer times?A.They developed very fast.B.They were large in number.C.They had similar patters.D.They were closely connected25.Which of the following best explains "dominant" underlined in paragraph 2?A.Complex.B.Advanced.C.Powerful.D.Modern.26.How many languages are spoken by less than 6, 000 people at present?A.About 6,800 .B.About 3,400C.About 2,400D.About 1,200.27.What is the main idea of the text?A.New languages will be created.B.Peoples lifestyles are reflected in languages.C.Human development results in fewer languages.D.Geography determines language evolution.The kids are hanging out. I pass small bands of students, on my way to work these mornings. They have become a familiar part of the summer landscape.These kids are not old enough for jobs. Nor are they rich enough for camp. They are school children without school. The calendar called the school year ran out on them a few weeks ago. Once monitored by teachers and principals, they now appear to be “self care”.Passing them is like passing through a time zone. For much of our history, after all, Americans arranged the school year around the needs of work and family. In 19th-century cities, schools were open seven or eight hours a day, 11 months a year. In rural America, the year was arranged around the growing season. Now, only 3 percent of families follow the agricultural model, but nearly all schools are scheduled as if our children went home early to milk the cows and took months off to work the crops. Now, three-quarters of the mothers of school-age children work, but the calendar is written as if they were home waiting for the school bus.The six-hour day, the 180-day school year is regarded as something holy. But when parents work an eight-bour day and a 240-day year, it means something different. It means that many kids go home to empty houses. It means that, in the summer, they hang out.“We have a huge mismatch between the school calendar and realities of family life,” says Dr. Ernest Boyer, head of the Carnegie Foundation for the Advancement of Teaching.Dr. Boyer is one of many who believe that a radical revision of the school calendar is inevitable. “School, whether we like it or not, is educational. It always has been.”His is not a popular idea. Schools are routinely burdened with the job of solving all our social problems. Can they be asked to meet the needs of our work and family lives?It may be easier to promote a longer school year on its educational merits and, indeed, the educational case is convincing. Despite the complaints and studies about our kids lack of learning,the United State still has a shorter school year than any industrial nation. In most of Europe, the school year is 220 days. in Japan, it is 240 days long. While classroom time alone doesn’t produce a well-educated child, learning takes time and more learning takes more time. The long summers of forgetting take a toll.The opposition to a longer school year comes from families that want to and can provide other experiences for their children. It comes from teachers. It comes from tradition. And surely from kids. But the most important part of the conflict has been over the money.28.The current American school calendar was developed in the 19th century according to ______.A.the growing season on nation’s farmB.the labor demands of the industrial ageC.teachers’ demands for more vacation timeD.parents’ demands for other experiences for their kids29.Why is Dr. Boyer’s idea unpopular?A.He thinks that school year and family life should be considered separatelyB.He argues for the role of school in solving social problems.C.He strongly believes in the educational role of school.D.He supports the current school calendar.30.“The long summers of forgetting take a toll” in the last paragraph but one means that ______.A.long summer vacation changes the way of learningB.long summer vacation has been abandoned in EuropeC.long summers result in less learning timeD.long summers are a result of tradition31.The author thinks that the current school calendar ______.A.is still appropriate B.is out of dateC.is inevitable D.cannot be revised三、单词拼写32.At first I disagreed, but on (反思),I realized she was right.(根据汉语提示单词拼写) 33.Children have a natural c (好奇心) about the world around them. .

Resident program assistants provide guidance, coordinate and lead social activities, ranging from group activities that include comedy shows to field trips.Your hard work will be combined with social events and fun activities —and you’ll still have time for your own adventures on campus! Email the SPP office at ******************.1. What does SPP aim to do?A.To help college students to achieve academic success.B.To provide admission guidelines for pre-college students.C.To get high school students well-prepared for college life.D.To encourage students to participate in hands-on learning.2. What are students supposed to do to earn the required credits?A.Carry out STEM research. B.Attend various seminars.C.Finish the courses online. D.Join in experiential learning.3. What can we know about students living on campus?A.They can organize social activities. B.They will have access to a single room.C.They are provided with good security. D.They are advised to direct comedy shows.“I can’t connect with your characters.”I kept hearing the same feedback and was unable to understand why and not sure what to do. I was a character-driven writer. How could I mess up the one thing I was supposed to be good at? I was determined to convince my agent that these characters were real. After all, I knew they were real. My main character Lotus had lived inside me for years. I just needed to clarify her on the page.I wrote and edited for a year, trying to respond to this agent’s feedback. But Lotus’ personality began to disappear. I tried to have her make “better” decisions, wear smarter fashion, and have more friends, as my agent said she acted “immature” and was “isolated”. And when this agent ultimately parted ways with me, I felt like I had failed. Now with time and distance, I realize I tried to fit Lotus into a neurotypical style to please my agent. And as a result, Lotus lost her Lotus-ness.When that agent discouraged me from writing Lotus as autistic(自闭的), he said that would make Lotus seem more “vulnerable(脆弱的)” or an “obvious victim”. I didn’t want Lotus to seem vulnerable. Lotus’ autism is what makes her powerful, I tried to explain. But from a neurotypical perspective, Lotus’ autism could only be seen as a weakness.Unsure of how to convince my agent of the strength and power autistic women hold, I began to write Lotus as “neurotypical”. And I failed miserably. After all, what do I know about being neurotypical? My whole life, autism was my default. Not being diagnosed until 2020, I assumed the way I saw the world was “normal”.My current agent encourages me to write from my neurodivergent(神经多样性的) experience. With this invitation, I revisited Lotus and saw her the way I first wrote her. And when I did, the characters and the entire narrative began to make more sense.Identifying my characters as neurodivergent not only gives me joy as a writer, but it has produced my strongest writing. For so long, I’ve combatted the advice to “write what I know”, in part because I didn’t know what I actually knew. I didn’t know I was neurodivergent. But a s I mine the specificity of my lived experience, my writing is stronger. There is a power to our lived experience. It’s not a limitation on our craft, but a swinging open of the gates.4. How did the author feel when receiving the repeated response from the first agent?A.Confused. B.Convinced. C.Determined. D.Disappointed. 5. Lotus’ personality got lost because ______A.Lotus no longer lived inside the author B.the author attempted to please the agent C.the agent failed to sympathize with Lotus D.Lotus was considered childish and lonely 6. What do we know about the author?A.She regretted parting with the agent.B.She owed her success in life to autism.C.She was aware of her autism in the early years.D.She was empowered by her autistic experience.7. What has the author learned from her own experience?A.Stick to your dream despite discouragement.B.Be true to yourself and write from your heart.C.Giving in to authority is the barrier to success.D.Everyone is born an original instead of a copy.At one time, the inheritance of traditional drama was difficult. People of insight screamed “save drama”. Many celebrities and big names put down their figures and went to the community to carry out public welfare performances of opera, and did everything possible to expand the coverage of drama. In recent years, traditional Chinese culture and art has gained a foothold on short video platforms and attracted a large number of young followers thanks to the explosive growth of the short video industry. Relaxing, emotional and fragmented, these video contents perfectly match the demands of the users. With the application of new technologies such as social communication and immersive experiencing, short video platforms are seeing more users, becoming a shining spot of new Internet media.Recently, Huangmei Opera “ Female Consort Prince ” became a hit on short video platforms as a lot of young users covered the aria (咏叹调) in their own way and showed great artistic talents. The interactive platforms are expanding the charm of the traditional opera among young people.Peking Opera was also well-received on short video platforms thanks to a series of augmented reality (AR) effects. Users love to film clips with a set of virtual facial makeup, headwear and costumes. Statistics indicate that these effects were applied by more than 18 million users, most of whom were young people.In addition to Chinese operas, intangible cultural heritage items, such as embroidery, paper-cutting, printing and dyeing, shadow play works, oiled paper umbrella making, and bamboo weaving are also actively promoted on short video platforms. In a word, short video platforms are becoming an important channel to display China’s intangible cultural heritage.Short video platforms, offering a fun, popular and easy way to explore the traditional art forms, are receiving a lot of positive feedbacks from China’s young generations. The seconds, or minutes long videos, along with unlimited possibilities as well as richness of styles, have produced remarkable achievements in promoting traditional Chinese culture.8. What mainly made the inheritance of traditional drama difficult?A.The slow growth of industry. B.The insufficient coverage of drama.C.The poorly-met demands of the users. D.The severe shortage of the drama actors.9. What led to the promotion of Peking Opera on short video platform?A.The social communication. B.The set of virtual facial makeup.C.The positive feedbacks from users. D.The application of new technologies.10. Why are paper-cutting and bamboo weaving mentioned?A.To expand the charm of traditional Chinese culture.B.To prove traditional art forms are actively promoted.C.To show the current situation of these cultural heritage.D.To offer new channels to display China’s cultural heritage.11. Which of the following is the best title for the text?A.The Bright Future of Huangmei Opera.B.The Explosive Growth of the Short Video Industry.C.The Simple Way to Explore the Traditional Art Form.D.The Creative Combination of Culture and Technologies.Several years ago, Jeremy Clarkson, presenter of the famous BBC television programme “Top Gear” discovered that one of his guests was half German and half Irish. Immediately, he said: “That's quite a strange combination. It's like, this must be done absolutely perfectly... tomorrow”.This joke played on stereotypes (刻板印象) of the Germans as efficient and the Irish as lazy. Many people could understandably be offended by these kinds of assertions (断言).We do not know every Irish person, so how can we then conclude that every Irish person is lazy?I recently read on a website that Irish business people were described as being 'generally rather casual' and more outwardly friendly than many European counties'. German business people, on the other hand, are considered to be very direct and according to the website, they do not need a personal relationship in order to do business. Once you hear advice like this,it becomes easier to understand where jokes like the one in the first paragraph come from.So why do some people disapprove of the kind of stereotypes as seen in Clarkson's joke, but not baring an eyelid (眨眼) when it comes to generalizations. What is the difference between the two?By definition, a stereotype is a widely held but fixed and oversimplified image or idea of a particular type of person or thing. A cultural characteristic, on the other hand, is a pattern of behaviour that is typical of a certain group.So what does this really mean? Stereotype are simply overstated assumptions about groups of people. Imagine if a tourist visited a small town in Switzerland and saw a number of locals playing the alphorn instrument, and then claimed that Swiss people can play the alphorn. This would be a stereotype! This is an overstated image of the Swiss which is based on one tourist's experience.If however, this tourist were to say that the Swiss are very punctual, this could be seen as a cultural characteristic. This is because it is a pattern of behaviour which is very typical in Switzerland: fromtheir transport system to their business meetings in this way, some people argue that generalizing another culture is not just useful. but important. Politicians always have to be mindful of the cultural characteristics of different countries. By becoming aware of different cultural characteristics,they can avoid causing offence (冒犯) in those cultures.However, others argue that generalizing cultures will always lead to offensive stereotypes. They argue that the best thing we can do is to stop generalizing cultures and start treating people as individuals.All this raises important questions: can making generalizations about groups of people be a positive thing? Or should we always avoid making broad assumptions about different groups?12. Whe n he said, “it's like, this must be done absolutely perfectly... tomorrow”,Jeremy Clarkson really meant________.A.the stereotypes of the Germans and the Irish are not so goodB.the combination of half German and half Irish is interestingC.the characteristics of the Germans and the Irish are oppositeD.the Germans will do it perfectly tomorrow while the Irish won't13. Which of the following is TRUE according to the passage?A.It's typical of the Swiss to be punctual.B.The Swiss can play the alphorn quite well.C.The Irish people are considered as lazy, direct and casual.D.The Germans are thought to be efficient, friendly and direct.14. Politicians think it important to generalize another culture because________.A.they don't want to offend other peopleB.generalizing will lead to offensive stereotypesC.cultural characteristics are better than stereotypesD.they think different cultural characteristics are useful15. The main purpose of this passage is to________.A.illustrate the importance of making generalizationsB.show it is wrong to play jokes on stereotypes of different peopleC.tell us the differences between stereotypes and cultural characteristicsD.discuss whether it is good to make generalizations about groups of people“Just think positively!”“It could be worse.”“You should look at the bright side!”We’ve all heard (and maybe used) these phrases without much thought. But they could be contributing to a culture of toxic(有毒的) positivity. For those new to this term, it might sound like an oxymoron(矛盾修辞法). How can positivity be toxic? Isn’t it supposed to be helpful, or “positive”, as the name suggests? 16“Toxic positivity is when somebody avoids all negative thoughts or feelings, pretending everything is going well when it is not,” explains Melissa Dowd, a therapist at PlushCare, a virtual health platform for primary care and mental health services.Whitney Goodman, the author of Toxic Positivity describes toxic positivity as the “endless pressure to be happy and pos itive, no matter what the circumstances are.” 17 It’s also something we can cause other people to experience. Expressing toxic positivity to others may look like offering them a simple solution to a complicated problem that we know nothing about, or not allowing people around you to appropriately express negative emotions.Toxic positivity causes us to suppress our emotions, which can make them worse. 18 “Although it can be helpful to look on the bright side when facing challenges,” Dowd says, “not copi ng with negative feelings in a healthy way in the moment can lead to those feelings resurfacing later in different areas of your life or as a form of anxiety.” 19 “If I feel like you’re going to dismiss me, I’m going to stop sharing how I’m feeling,” Goo dman adds.20 If you’re using toxic positivity against yourself, Goodman suggests remembering it’s OK if you’re upset about something. It’s valid if something annoys you. “Allow ourselves and other people to share when they’re going through a difficult time,” she says. Dowd adds that it’s essential that “we all learn to cope with and process our emotions in a healthy way as opposed to avoiding how we feel” as life’s stressors continue to rise. For example, instead of simply saying “Just think positively,”we’d better say “Sometimes bad things happen. How can I help?”This Too Shall PassWhen my family moved to Ohio over the summer, I feared attending another new school and knowing no one because I was able to expect what was coming. I had bright red hair and enormous glasses. In addition, I was_______and not very sociable.Boarding the school bus that first day, I felt like all eyes on me. I could hear the_______“She’s huge!” Obviously, the kids on the bus had known each other well. I spent that first bu s_______in silence.The following day was even_______. I did not notice that a few boys had tied a shoelace across the aisle and thus fell face first on the bus, _________everything I was carrying. _________I was embarrassingly gathering my supplies, I cou ld hear the laughter, and then the_______“That felt like an earthquake!” Anyway, I_______ to find a seat. Looking out of the window, I_______the tears welling up in my eyes.It was then that I sank into myself. I began walking everywhere. I would wander through the woods behind our house.
