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:“姜还是老的老”“我上次听到这句话,还是在上次”……这类毫无意义却又挑不出毛病的语句,被人们戏称为“废话文学”。
在信息获取和观点表达日益便捷的今天,这类对文本符号的二次改造与“语言玩梗”大行其道,不禁让人好奇,互联网语境下,“不好好讲话”的魔力究竟在哪儿?最初的“废话文学”,内含着人们戏谑、反讽与抵抗意味的阴阳怪气。
过去“路遥车马慢”,信息承载量与传播速度都很低,寄信隔着万水千山,发短信要字斟句酌,人们恨不得一句话把所有事情讲完。
互联网时代,看完某篇形式主义言辞空洞的文章,围观一个长达几分钟但内涵不超过两句话的无效视频,大家惊觉,原来互联网时代,早已不是“听君一席话,胜读十年书”。
出于对低信息增量内容的不满,人们开始用语言予以反击。
这一届年轻人偏爱“躺平”,消解无用信息的方式,就是用同样的“无意义”进行风险对冲。
于是,“废话”式名言警句被改造出来,并活学活用于各类语境。
“废话文学”的生产十分简便,把单位从分钟变成秒、用同义词西红柿替换番茄……实在不行,还可以向鲁迅先生学习,把说过的句子再说一遍,“你说了两句话,一句是废话,另一句也是废话”。
由此一来,“不好好说话”便演变成某种社交策略,“废话文学”在本身语义之外,逐渐衍生出各场景独有的意义和情绪表达。
面对朋友空洞的长篇大论,一句“除了内容,你说得都挺好”,就能以戏谑的口吻表达出某种不满,含蓄中夹着杀伤力,对方也不至于下不来台。

山东省菏泽市第一中学2024-2025学年高一上学期10月月考英语试题一、阅读理解When you are about to go to a boarding school (寄宿制学校) in England, there are many different questions that may come to mind. But once you look at them with some perspective (视角), you will certainly feel easy. Here is a normal boarding day.Early Morning:Usually boarders get up around 7:00 am and have around an hour to take a shower and put on their uniform before breakfast.Lessons:Classes start at 9: 00 am and every lesson lasts for 50 minutes. After two lessons, at 10: 40 am, you’ll have a short break. The next period of classics will include two more lessons.Lunch:Lunch is usually held around 12:30 pm at the dining hall, where you’ll join your friends to enjoy a hot dish. After an hour of lunch, you’ll have three or four more lessons to attend.Dinner:At 5:00 pm you will have finished your school lessons for the day. Most boarding schools in the UK offer their full boarders different kinds of hot meals to choose from.Activities/ Sports:All boarding schools in the UK provide many different kinds of activities for their boarders, such as football, swimming, golf or art.Prep:An important part of boarding school life is the supervised homework session known as “prop”. Although “prep” might sound stressful, it’s a great way for you to keep up with your studies.Free time:Once you have done all your classes and activities, it’s time to relax.Bedtime:In most boarding schools, the lights go out around 10:30 pm.Being nervous just before you go to a boarding school is completely normal and understandable. Hopefully, knowing the usual routine (常规) can help you. Once you are there, you will also see how exciting life in a boarding school in England can be.1.What can help you keep up with your studies in the boarding school?A.Doing activitıes.B.Having lessons.C.Enjoying free time.D.Supervised homework sessions.2.What do we know about boarding schools in England from the text?A.Classes usually start at 8:30 am.B.Students can have a short break after four lessons.C.They don’t give students any free time.D.They turn off the lights around 10:30 pm. 3.What is the purpose of the text?A.To help students know about boarders’ life.B.To attract more students to boarding schools.C.To introduce a new school life.D.To advertise for boarding schools.I want to share with you a story from 28 years ago. My dad was a used car salesman. Every Thursday night, he would head off to Shreveport, LA for an auction (拍卖会). Most of the time, I drove a car over there for him so he could sell it at the auction.One day I was riding with my dad when he noticed a hitch-hiker (搭便车的人) with a backpack. Without hesitation, he pulled the car over and offered him a ride. Dad asked him his name, and proceeded to talk to him about all sorts of things. Dad asked him where he was going. The hitch-hiker told him that he was heading for the west. I can’t recall why but he told Dad a lot of things that had occurred to him and that persuaded him to make that decision. He talked about the tragic events that occurred to him several years before. He was in low spirits, but I could see that the hitch-hiker’s attitude was changing as someone was really listening to him.We drove 45 minutes before the hitch-hiker got off. We pulled over and Dad told him to keep his head up and things would start looking up for him soon. He reached into his pocket and handed the hitch- hiker a twenty-dollar bill. The guy smiled. He nearly lit up right there on the cold, dark highway.We drove on and my dad did not say a single thing. I was still completely surprised by what I had just witnessed. I was always told by everyone never to pick up a hitch-hiker and yet my dad did it every single time he saw one. While reflecting upon that story I came to understand that just one single kind act could change someone’s life. And I am sure that my father’s deed made that poor man’s day.4.What made the hitch-hiker become less upset?A.The writer’s father talking to him about all sorts of things.B.The writer’s father offering him a free ride.C.The writer’s father really listening to him.D.The writer’s father agreeing to drive him to his destination.5.When his father helped the hitch-hiker, the writer ___________.A.was deeply moved B.strongly disagreedC.admired his father D.couldn’t understand6.Which of the following words can be used to describe the father?A.Wealthy.B.Warm-hearted.C.Far-sighted.D.Adventurous.7.What’s the writer’s main purpose of writing this text?A.To tell a story of his father.B.To show his respect for his father.C.To prove his father is the best teacher.D.To advise people to learn from the hitch-hiker.What you do after studying could have a big effect on how well you learn and remember. Today on Education Tips, we will explore two no-cost ways that can help you improve your learning: wakeful rest and sleep.When many students finish studying, they often go straight to another activity. Perhaps they look at their phone or computer. They might even play a video game or watch television. But research suggests that resting after your study may help you remember what you have studied.The basic idea is this: by stopping your activity after the study, your brain gets a chance to rest. Resting is difficult when you are playing computer games.While this might sound unusual to you, many studies have explored the benefits of resting after learning—what is called “wakeful rest”.A 2019 study found that both young and older adults were able to better remember information they learned after doing wakeful rest.If you want to give “wakeful rest” a try, here are a few simple things to do. Rest quietly for five to ten minutes. Do not look at your phone, read stories or play games. It is really that easy!Besides wakeful rest, sleep is also important for learning. The Division of Sleep Medicine at Harvard Medical School (HMS) notes that sleep helps people to learn in two ways. A report on the school’s website explains that “a sleep-deprived person cannot focus attention well and therefore cannot learn well”. It also says, “Sleep itself helps us to memorize and that memorizing is very important for learning new information.”The National Sleep Foundation (NSF) suggests that adults between the ages of 20 and 64 get between 7 and 9 hours of sleep per day. Teenagers may need a little bit more, and people over the age of 65 may need a little less.Try to get some “wakeful rest” after a study. Then try to get a good night’s sleep. That’s it—a simple, no-cost way to help you remember what you learn.8.What is paragraph 3 mainly about?A.The importance of sleep.B.The good ways to get a rest.C.The reason for having a rest.D.The types of resting activities.9.Which activity might be recommended shortly after studying?A.Reading a newspaper.B.Playing a video game.C.Sitting there doing nothing.D.Having a nice sleep at night.10.How long should teenagers sleep each day according to NSF?A.Less than 7 hours.B.Just 7 hours.C.No more than 9 hours.D.Around 9 hours.11.What can be a suitable title for the text?A.Low-cost Tips on Working B.Good Things to Do After Your StudyC.Why Do We Need to Have a Good Sleep?D.How Long Should We Rest AfterLearning?Exams are brain-burning. The silence of the hall; the beating of the clock; the watchful eye of the teacher; the proud expression of the person who has finished 15 minutes early. So it is not surprising that those who feel anxious in the exam do worse than those who do not. But different from the existing(现存的) point of view, the recent study by Maria Theobald shows that the pressure of revision affects(影响) your exam performance.To test this idea, Dr Theobald worked with 309 German students who were preparing for their final exam. During the 100 days before the real exam, these students used an online learning app which showed them old exam questions and recorded their performance. And 40 days before the real exam, they also took a mock(模拟) exam. Their levels of anxiety were also be recorded and assessed(评定), every day for 40 days before the real exam and also on the day of that exam.The result was not what she expected. Anxiety on the day of the test did not predict(预测) exam performance at all. It was the level of knowledge in the mock exam and the earlier practices that predicted it. Those who performed well in the mock exams also did well in the real test, no matter how anxious they were on the day.It turned out that what really affected students were high levels of anxiety during the weeks before the exam. The greater a student’s anxiety in the days before the exam, the lower his or her knowledge gain was. To reduce this anxiety, she gives some advice for students when they revise. First, they can raise their confidence in their own abilities by reminding(提醒) themselves of how much they know. Second, they can diminish the importance of the test by reminding themselves that, though it is important, it is not a life or death situation. It really isn’t.12.What influences exam results according to the existing view?A.Exam levels.B.Exam schedule.C.Pressure from the exam hall.D.High expectations(期望) from teachers. 13.How did Dr Theobald go on the study?A.By asking students some questions.B.By collecting the data(数据).C.By asking experts` advice.D.By following students’ performances. 14.What does the underlined word “diminish” probably mean in the last paragraph?A.Reduce.B.Influence.C.Realize.D.Understand. 15.Which of the following is the suitable title for the text?A.Never Too Late to Revise B.Never Put Off Revision till TomorrowC.Anxiety in Revision, Failure in Exam D.The More Pressure, The Better ResultsPeer PressurePeer pressure is a part of life. 16 This peer group may be of similar age but can also be defined by other commonalities (共同点), including motherhood, professional affiliations, and your local neighborhood.Peer pressure is not always negative. Trying to fit into a healthy social group, for example, of peers getting good grades, joining sports teams, and making plans for their futures, is positive.17 Peer influence can show you there is support, encouragement, and community available to you. By seeing someone else do something positive, you may reflect on your own life choices, goals, and where you spend your time.18 Being pressured by peer, whether it happens in person or online, may shake your sense of identity and self-confidence. For example, you may feel pressure to do unsafe things that have risks you may not fully know.19 You can also work on surrounding yourself with more positive influences. Some ways of coping with peer pressure include:● Not spending time with people who pressure you to do things that feel wrong or dangerous.● Learning to say “no” and practicing leaving situations that feel unsafe or uncomfortable.● Talking to a trusted peer or professional (teacher, counselor) if you have problems saying “no” or are feeling pressured to change something about yourself.● 20In the journey of life, peers influence our steps. If you embrace positive guidance and stand firm against negativity, you can become the architects of your own story.A.Some refer to this type of peer “pressure” as peer “influence”.B.It can be direct or indirect, positive or negative.C.It is any type of influence that comes from a peer group.D.Getting over peer pressure means not accepting the negative influence of others.E.While peer influence can improve your life, peer pressure can cause problems.F.Feeling pressured to do things that may make you feel bad about yourself is unhealthy.G.Befriending people who have a positive influence.二、完形填空Jenna had graduated from middle school and was ready for new 21 in high school.22 , high school was different.

吉林省部分学校2024-2025学年高一上学期10月月考语文试题

2024-2025学年度上学期第一次月考高一语文试题本试卷共24题,共150分,共5页。
考试时间为150分钟。
考试结束后,只交答题卡。
一、现代文阅读(35分)(一)信息类文本阅读(本题共5小题,19分)阅读下面的文字,完成下面小题。
赵艳(以下简称赵):很多读者对你的认识是从《哦,香雪》开始的,这是一篇意境和文字都非常优美的文章,可以说是当代文学中诗化小说的代表作之一。
这篇文章读起来很有青春的诗意和激情,一气呵成,像是从生命中活泼泼地流淌出来的东西,很感性,也很朴实。
你自己如何评价这篇作品在你所有创作中的地位和价值?铁凝(以下简称铁):它在我整个创作中不是以价值高或低,分量轻或重来衡量的,而是它本身具有一种不可替代性,我后来的小说在叙事上更成熟,更像一个自觉作家的写作,但《哦,香雪》焕发出来的对人生、对情感、对生活、对希望那种透明的激情是不可替代的。
一个年轻的作家,如果有本领,写出那样的作品并不难,但是岁月过去了,我们经历了很多,如果还保有那样的爱和希望,还拥有那种透明的心境,那就真是不容易的。
我想,《哦,香雪》对我的意义就在这里。
现在,香雪的时代好像已经过去了,我歌颂的也的确不是封闭的处于蒙昧状态的大山里的人和事。
生活在变,生活里的人也在变,但是我们依然需要香雪。
孙犁说过:“女孩子们心中,埋藏着人类原始的多种美德。
”我认为,发掘我们内心的多种原始美德是任何作家在任何时代都不应该放弃的,哪怕在经历了人生的苦难之后,外在的形式变了,内部那个坚硬的核应该还在。
赵:无论是美还是丑,无论外壳怎样变换,内在的核始终如一地朝向对人类美好的情感、珍贵的品性的追求。
铁:是的。
我的作品中前后的人物和故事都有鲜明的不同,中间还有一些起伏。
文学可以而且应该有多种途径,有时是这个故事触动了你,有时是那个人使你有倾诉的愿望,但最终我将这些人和事融合在一起,通过他们,我想要实现的是文学温暖世界的功能。
汪曾祺说过“人是孤儿”,人真的是很孤独的,所以人需要文学的世界、希望的世界,虽然也许那最美好的境界,我们永远到达不了,但愿望在那儿,我们就会有向前走的勇气,对生活有所期待,这就够了。

当0a =时,{}0B =,此时A B ⋂=∅,当0a >时,{B =; 又11,,12A ⎧⎫=−⎨⎬⎩⎭,若A 与B 构成“全食”,则B A ⊆, 当a<0时,满足题意;当0a =时,不合题意;当0a >时,要使B A ⊆,则{}1,1B =−1=,解得1a =; 综上,A 与B 构成“全食”时,a 的取值范围是{|0a a <或}1a =; 若A 与B 构成“偏食”时,显然0a ≤时,不满足题意,当0a >时,由A B ⋂≠∅,所以11,22B ⎧⎫=−⎨⎬⎩⎭12=,解得14a =,此时a 的取值范围是14⎧⎫⎨⎬⎩⎭.故答案为:{|0a a <或}1a =;14⎧⎫⎨⎬⎩⎭三、解答题(本大题共4小题,共45分.解答应写出文字说明,演算步骤或证明过程)16. 【答案】(1)(1,1]A B ⋂=−,(1,)UA B ⋃=−+∞;(2)(0,1]【分析】(1)解一元一次不等式求集合A ,再应用集合的交并补运算求A B ⋂及()UA B ⋃.(2)由集合的包含关系可得2a ≤2,结合已知即可得a 的取值范围. 【小问1详解】由211x −≤得:1x ≤,所以(,1]A ∞=−,则(1,)UA =+∞,由(1,2]B =−,所以(1,1]A B ⋂=−,(1,)UA B ⋃=−+∞.【小问2详解】 因为C B ⊆且0a >, 所以2a ≤2,解得1a ≤. 所以a 的取值范围是(0,1]. 17. 【答案】(1)34m ≤ (2)1m =−【分析】(1)根据根的判别式列不等式,然后解不等式即可;(2)根据韦达定理得到1223x x m +=−+,212x x m =,然后代入求解即可.【小问1详解】因为有两个实根,所以()222341290m m m ∆=−−=−+≥,解得34m ≤. 【小问2详解】由题意得()122323x x m m +=−−=−+,212x x m =,所以2236m m −+=−,整理得 ()()310m m −+=,解得3m =或-1,因为34m ≤,所以1m =−. 18. 【答案】答案见解析【分析】分别求解集合,A B ,并求解三个条件的集合,再根据必要不充分条件,转化为集合的包含关系,即可列式求解. 【详解】不等式8831100222x x x x x x +++>⇔−>⇔<−−−,即()()320x x +−<, 解得:32x −<<,即{}32A x x =−<<,()()22240220x mx m x m x m −+−<⇔−−−+<⎡⎤⎡⎤⎣⎦⎣⎦,解得:22m x m −<<+,即{}22B x m x m =−<<+, 若选①,{3UA x x =≤−或2}x ≥,:p {3U x A x x ∈=≤−或2}x ≥,{}:22q x B x m x m ∈=−<<+,若p 是q 的必要不充分条件,则BUA ,即23m +≤−或22m −≥,解得:5m ≤−或4m ≥;所以存在实数m ,使得p 是q 的必要不充分条件,m 的范围为5m ≤−或4m ≥; 若选②,{}12A C x x ⋂=−<<,:p {}12x A C x x ∈⋂=−<<,{}:22q x B x m x m ∈=−<<+,若p 是q 的必要不充分条件,则B ()A C ,则2122m m −≥−⎧⎨+≤⎩,解集为∅;所以不存在实数m ,使得p 是q 的必要不充分条件; 若选③,{}34A C x x ⋃=−<<,:p {}34x A C x x ∈⋃=−<<,{}:22q x B x m x m ∈=−<<+,若p 是q 的必要不充分条件,则B ()A C ,则2324m m −≥−⎧⎨+≤⎩,解得:12m −≤≤;所以存在实数m ,使得p 是q 的必要不充分条件,m 的取值范围为12m −≤≤; 19. 【答案】(1)答案见解析 (2)不具有,理由见解析【分析】(1)根据集合A 具有性质J 的定义即可得出答案;(2)当6n =,4m =时,利用反证法即可得出结论. 【小问1详解】当3n =时,{}1,2,3A =,集合A 的所有二元子集为{}{}{}1,2,1,3,2,3,则满足题意得集合B 可以是{}1或{}2或{}3,此时1m =, 或者也可以是{}1,2或{}1,3或{}2,3,此时2m =; 【小问2详解】当6n =,4m =时,{}1,2,3,4,5,6A =,假设存在集合B ,即对任意的()1234,,,,4,114i A A A A B B A i =⋂≤≤≤,则取{}{}{}{}12341,2,3,4,5,6,2,3A A A A ====,(4A 任意构造,符合题意即可) 此时由于4B =,由抽屉原理可知,必有()223i B A i ⋂=≤≤, 与题设矛盾,假设不成立, 所以集合A 是不具有性质J .【点睛】关键点点睛:此题对学生的抽象思维能力要求较高,特别是对数的分析,在解题时注意对新概念的理解与把握是解题的关键.。

The next building was only a few feet away from mine. There was a woman living there, and I had never met her, yet I could see she sat by her window each afternoon, sewing or reading.After several months had gone by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I would say to myself, “I wonder why that woman doesn’t wash her window. It really looks terrible.”One bright morning I decided to clean my flat, including washing the window on the inside.Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly visible (可见的). Her window was clean!Then it dawned on me. I had been criticizing (批评) her dirty window, but all the time I was watching hers through my own dirty window.That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own shortcomings?Since then, whenever I wanted to judge someone, I asked myself first, “Am I looking at him through my own dirty window?” I try to clean the window of my own world so that I may see the world abo ut me more clearly.25. “It dawned on me” in paragraph5 probably means “_______”.A. I began to understand itB. it cheered me upC. I knew it grew lightD. it began to get dark26. It’s clear that ________.A. the writer had never met the woman beforeB. the writer often washed the windowC. they both worked as cleanersD. they lived in a small town27. From the passage, we can learn _______.A. one shouldn’t criticize others very oftenB. one should often make his windows cleanC. one must judge himself before he judges othersD. one must look at others through his dirty windowsCBooks are for reading, but man must bring to their reading a desire to learn and a power of absorbing. Reading should be active, not passive.When students first go to a library, they may be at a loss as to what to read of all the different subjects. Well, Bacon tells you to “look at weak places in your armor(盔甲)”, and shows you how to fill up the blanks in your knowledge. On the other hand, it is no good just trying to fill your mind with knowledge. Knowledge in itself is often useless. A mind filled with too much knowledge is like a room too full of furniture; a man cannot walk about freely in it, and look out of the windows. It is much better to concentrate on a few subjects which interest you and to deal lightly with the others than to march heavily through the whole range(范围) of learning, like a silly tourist going through a museum and not missing a single object. If you try to master every subject you may become very wise, but you will be very lonely and you will probably lose all your friends. So you must learn to pick and choose, and you must also learn to look here and there in a library likea camel eating grass on the grass land. If you watch it eating, you will see that although it is supposed to be one of the most stupid animals in the world, it has at least one of the qualities of the cultured man, the power to pick and choose.

Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fad but a lifestyle.On April 22, 2011, we decided to go green every single day for an entire year. This meant doing 365 different green things, and it also meant challenging ourselves to go green beyond easy things. Rather than recycle and reduce our energy, we had to think of 365 different green things to do and this was no easy task.With the idea of going green every single day for a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all the green things that could be done to help the environment. We wanted to push the message that every little bit helps.Over the course of Our Green Year, we completely changed our lifestyle. We now shop at organic(有机的)stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office, anyone caught doing something ungreen might be punished.Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planet.32.
