2025届湖南省长沙雅礼中学高三第一次模拟考试语文试卷注意事项1.考生要认真填写考场号和座位序号。

2.试题所有答案必须填涂或书写在答题卡上,在试卷上作答无效。

第一部分必须用2B 铅笔作答;第二部分必须用黑色字迹的签字笔作答。

3.考试结束后,考生须将试卷和答题卡放在桌面上,待监考员收回。

1、阅读下面的文字,完成下列小题。

中国在2001年前几乎没有世界级的超算产品,因为构建一整套全球顶级的超算系统,也并非堆砌处理器这么简单。

中国超算研发的全面崛起,是建立在强有力的计算个体芯片、先进的运算管理技术和可靠的操作系统支持基础之上的。

芯片无疑是超级计算机的核心部分,一台超算产品至少装有几千枚甚至数万枚CPU和GPU芯片,同时配备特殊的操作系统,负责管理这些芯片之间如何合作,进行一系列复杂的运算,才能真正使之拥有十分可靠的强大算力。

国防科技大学分别在2010和2013年建造的“天河一号”和“天河二号”超级电脑,都曾登顶世界超算TOP500榜单,两者都主要使用Intel和AMD提供的芯片。

2015年4月,美国政府宣布制裁中国四家超算中心,禁止向中国超算中心出售Intel的Xeon Phi超算芯片。

天河二号就因为美国的制裁,耽搁了升级计划,不得已调整技术路线,并且采用国产矩阵2000替换Intel的Xeon Phi。

但这无法阻止中国超算研发的强势崛起。

2017年,广州超算中心宣布使用国产矩阵2000芯片,升级了天河二号超算系统,并成功实现算力翻倍。

而神威·太湖之光超级计算机起初就安装了40960个中国自主研发的“申威26010”众核处理器,而且性能不俗。

多年以来,计算机CPU芯片一直遵循摩尔定律进行升级迭代。

但摩尔定律也是有极限的,集成电路上的元器件已经足够小,己经逼近“原子尺度”了。

很难再延续过往路径进行升级迭代。

这个时候,就要想办法挖掘计算机的系统潜力。

在挖掘计算机系统潜力方面有两个思维路径:一个是阿里方案,一个是联想方案。

Fill in each blank with the word or phrase that best fits the context.Night after night, she came to tuck (将棉被盖好) me in, even long after my childhood years. Following her longstanding 36 , she'd lean down and push my long hair out of the way, then kiss my forehead.I don't remember when it first started 37 me---her hands pushing my hair that way. But it did annoy me, for they felt work-worn and 38 against my young skin. Finally, one night, I shouted out at her, "Don't do that anymore----your hands are too rough!" She didn't say anything in reply. But never again did my mother 39 out my day with that familiar expression of her love.Time after time; with the passing years, my thoughts returned to that night. By then I missed my mother's 40 , missed her goodnight kiss on my forehead. Sometimes the incident 41 very close, sometimes far away. But always it lurked (潜伏), in the back of my mind.Well, the years have passed, and I'm not a little girl anymore. Mom is in her mid-seventies, and those hands I once thought to be so rough are still doing things for me and my 42 . She's been our doctor, reaching into a medicine case for the treatment to 43 a young girl's stomach or relieve the boy's scraped (擦伤) knee. She cooks the best fried chicken in the world …gets 44 out of blue jeans....Now, my own children am grown and gone. Mom no longer has Dad, and on 45 occasions, I find myself drown next door to spend the night with her. So it was late on Thanksgiving Eve. As I slept in the bedroom of my youth, a familiar hand hesitantly 46 my face to brush the hair from my forehead. Then a kiss, ever so 47 , touched my brow.36. A. thought B. track C. advice D. custom37. A. annoying B. disappointing C. delighting D. interesting38. A. warm B. cold C. rough D. comfortable39. A. let B. close C. make D. work40.

A. gently B. suddenly C. heavily D. deliberatelySection C Directions: Complete the following passage by using ONE word that fits the context. During my childhood many years ago,a hero was pictured in my mind as the strong and thepowerful ,such as a superman, but 48 time goes by and my knowledge grows wider, the definition of a hero changes 49 a superman to Jesus Christ. In my opinion, a hero should have a modest characteristic,treat others with love and have the ability to change the world.Heroes are also ordinary men 50 they do extraordinary things for others out of the vast love 51 they have in heroes' heart. When God created the world, God gave everyone a lovely heart for a chance to become a hero. 52 people need to do is to spare out the love to become heroes, but this world only has not so 53 heroes.Who doesn't like to give orders to other people? Who likes to be a servant treated like a dog? Everyone wants to get to a higher position. The employee wants to be a manager. The senator(参议员) wants to be the president. The higher status will have 54 stronger power. No one will refuse to own the driver seat. So a hero must have the ability to be in the rank(职位). The hero doesn't have to take the power,but to get to a higher rank is one way to get ability of changing the world. If the hero can not change the world,he is 55 a normal man with a modest characteristic and kind love. Besides, a hero should be ready to help others.PART THREE: READING COMPREHENSIONDirections: Read the following passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A, B, C and D. choose the one that fits best according to the information given in the passage.ACOOL INVENTIONSFor light sleepersMillions of people have trouble falling asleep each night, which is why Light Sleeper was created.Developed in the United Kingdom, Light Sleeper's makers say it can help a person fall asleep and also help a person fall back to sleep after waking up in the middle of the night.Light Sleeper works by projecting (投射) a light onto the ceiling while the person is lying down. The idea is to watch the light, because the light moving in a circle has a relaxing effect.One of the advantages of the product is that it won't disturb other people in the room. The product can be easily moved and will switch itself off after 30 minutes to save power.Stop the snoring (打鼾)Here's a new product designed to slow down the frequency and level of your snoring. The Snore Stopper has a sensitive instrument that will detect when you're snoring. Once it does that, it will send a very mild electronic signal to your wrist. This consequently changes your sleeping position to stop you from snoring. The Snore Stopper; won't cause any damage to your body.Get your true colorsPhotoshop features a pen that will copy the color settings of what you are monitoring onscreen to use as a color in your program. Now an off-line product allows you to pick a color when not using the computer software.The Color Picker is a concept pen. After placing the pen against an object, the user just presses the scan button. Color sensors (感应器) inside the pen send information to a box, which then mixes red, green and blue to produce the desired ink color.Keep it freshMore high technology products are showing up in the kitchen. A new Bagel dome (圆顶形物)advertises that it will keep your baked goods fresher for longer periods of time. The product, which is able to remove air, works for bread rolls, cakes and other perishables. To use it, you just push a button at the top.56. How can Light Sleeper help a person fall asleep?A. Its light makes people feel calm.B. It doesn't make any noise.C. It is fixed on the ceiling.D. Its light moves fast.57. What do we know about the Snore Stopper?A. It will cause slight damage to a person's body.B. It will wake a person up once he starts snoring.C. It can make sure a person doesn't snore all night.D. It can make a person snore less by changing his sleeping position.58. The Color Picker will probably be used while you're .A. using the computerB. drawing picturesC. collecting informationD. designing a program59. The underlined word "perishables" in the last paragraph refers to foods which .A. are easy to keepB. go bad easilyC. are rich in vitaminsD. keep you thin60. It can be learned from the passage that .A. the Color Picker is convenient to useB. Light Sleeper was designed by an AmericanC. the Bagel dome mainly serves as decorationD. few people would like to try the Snore StopperBAmerican kids are taking more tests than ever before, and they're stressed out. Is help on the way? Just the sight of a test booklet makes some kids sweat. For others, it is a blank answer sheet. Then there are the dreaded words, "Take out your Number 2 pencil." All these fill 10-year-old Chelsea Logo with fear. "I start to tap my pencil on the desk," says the fifth grader from Toluca Lake Elementary, near Los Angeles, California. "Then I feel the butterflies in my stomach."Chelsea is not alone. In a recent survey by Kids Health£.org, more than 70% of kids aged 9 to 13 said they worry about tests. It's no wonder. Across the United States, public schools give more than 250 million standardized tests each year.Why do kids have to take so many tests? The No Child Left Behind (NCLB) law requires that students in grades 3 through 8 be tested each year. The law's goal is for all students to be at grade level by 2014. Students must pass the tests and meet other requirements or their schools may be shut down.The U.S. Secretary of Education Arne Duncan wants to change NCLB. But that doesn't mean hefavors getting rid of tests. Duncan believes tests should be used mainly to evaluate kids' strengths and weaknesses. Tests, Duncan says, should not be used to punish kids or their schools for failure. "The goal is to focus on great teaching and learning," Duncan said.Under NCLB, each state sets its own standards for students to meet. The result, Duncan says, is that states are making the tests easier. To fix this problem, 48 states are now working together to create common standards. "I want to set a high bar for kids, " Duncan says, "so they'll be in great shape to achieve their dreams."Like them or not, tests are here to stay. So how can you handle test nerves? Schools are teaching students to relax through. deep breathing. and stretching (伸展运动) . In Oakland, California, Principal Zarina Ahmad of Piedmont Avenue Elementary leads her students in a cheer to get them excited about learning."Kids are under high pressure," says Ahmad. "There has to be time for kids to be kids. Still, we need tests to help us assess what students have yet to learn."61. The underlined part "the butterflies in my stomach" can be replaced by .A. guiltyB. nervousC. excitingD. proud62. According to the passage, the NCLB law .A. is focusing on teaching methods in schoolsB. is requiring schools to make the tests more difficultC. is trying to make schools be responsible for studentsD. aims to evaluate kids' strengths and weaknesses by means of tests63. We can learn from the passage that Arne Duncan .A. is strongly against testsB. suggests closing some schoolsC. is concerned about students' developmentD. suggests each state set its own standard64. We can learn from the last two paragraphs that .A. it's possible to get rid of testsB. schools have no good way to deal with students' stressC. tests help assess what students have to learnD. schools are aware of students' stress caused by tests65. What would be the best title of the passage?A. Why kids are more stressed than before?B. Kids' tips for test successC. How to deal with test stressD. Put kids to the standardized testCScientists are fond of running the evolutionary clock backward, using DNA analysis and the fossil record to figure out when our ancestors stood straight and split off from the rest of the primate evolutionary tree. But the clock is running forward as well. So where are humans headed? Here's a thoughtless assessment of possible paths, ranging from similar humans to alien-looking hybrids bred for interstellar (星际的) travel.Different populations of a species have to be separated from each other in order for thosepopulations to diverge into separate species. Populations are increasingly in contact with each other,leading to greater gene-mixing. It's believable that separate species would appear. Evolution is still at work and the trend may well be accelerating. Cultural diversity is fading as human society becomes more interconnected globally.The radical king of evolution moves much more quickly than biological evolution. High-tech improvements are ranging from Supermen, to camera-equipped flying drones(遥控飞机), to pills that keep soldiers going without sleep or food for days. To date, genetic medicine has focused on therapies that work on only one person at a time. The effects of those therapies aren't carried on to future generations. Tinkering with the germline could conceivably produce a superhuman species in a single generation-but could also conceivably create a race of monsters.Today the rapid pace of cybernetic(计算机控制论的) change has led to worry that artificial intelligence may outpace human’s natural smarts. In some fields, artificial intelligence has already bested human. We're already making machines that can be assimilated (同化) including artificial limbs, mechanical hearts, and artificial retinas (视网膜).If humans survive long enough, there's one sure way to grow new branches on our evolutionary family tree: by spreading out to other planets. If humans established a permanent settlement on other planets, the radically different living conditions would change the evolutionary equation (方程式) What will be inconceivable millions of years from now? Two intelligent species, human and machine, definitely work together to spread life through the universe.66. Scientists study the evolution according to .A. different populations of a speciesB. DNA analysis and the fossil recordC. cultural diversity and greater gene-mixingD. high-tech enhancements and biological evolution67. Which is NOT true about human beings' evolution?A. New species will appear.B. Human's evolution is faster than biological evolutionC. Cultures will become more colorful.D. The evolution might create a race of monsters.68. What's the meaning of the underlined word "therapies" in Paragraph 3?A. Treatments.B. Diseases.C. Medicines.D. Theories.69. What might bring threat to human beings?A. Supermen.B. Monsters.C. Alien.D. Artificial intelligence.70. Which of the following must happen in the future?A. Humans survive long enough.B. Humans spread out to other planets.C. Human and machine work together.D. Living conditions change the evolutionary equation.PART FOUR WRITING (45 marks)SECTION A (10 marks)Directions:Read the following passage. Complete the diagram by using the information from the passage. Write NO MORE THAN THREE WORDS for each answer.Computers completely rule the life of an average student in any corner of the world in the formof hand-held devices, or printed textbooks (thanks to the use of computers in printing). What follows are some instances of the use of computers in education.Without computers, learning would be restricted within the walls of institutions. Knowledge and education are being empowered, and the best way to make them accessible to everyone is through computers. Working professionals, stay-at-home parents, senior citizens, even curious minds benefit from online education. E-Learning is accessible and people can afford it.We all know how learning about the depth of the Mariana Trench in geography class can be a little boring for young children. However, by introducing the audio-visual method of learning, computers have made education interesting. As communication systems enhance, education will change for the better-computers will make our children more curious, because they know that the answers to their questions are at hand.The Internet is now what once used to be the library. What’s more, it is easier to access, al ong with being a convenient and fairly reliable source of information.Computers have more or less eliminated paperwork in the administration section of education. Thanks to websites, we can do away with printing brochures, application forms, admission and other administrative documents, resulting in procedures that are cost-effective and environment- friendly.Unfortunately, computer technology has also brought about easier means for students to cheat on their homework. Since most homework is typed, teachers cannot rely on comparing different forms of handwriting. In addition, students can merely copy work from the Internet. So students should make good use of computers and teacher and parents should monitor and educate them too.Anyway, there is no questioning over the impact of computers in education; their usage has completely revolutionized the way education is received, communicated and processed. In the years to come, more changes are expected; changes that will further refine the field of education.SECTION B (10 marks)Directions:Read the following passage. Answer the questions according to the information given in the passage.World-famous politician and civil rights hero Nelson Mandela died on December 5 at age 95. For many years, Mandela fought to end racial segregation in his home country of South Africa. He became a hero to the many all across the world.In the 1950s, Rolihlahla "Nelson" Mandela became the leader of a group in South Africa called the African National Congress (ANC). The group fought to end racial segregation. This put Mandela at the top of the government’s enemies list. He often had to live in hideouts and wear disguises. Activists like him were often beaten or murdered.Mandela was accused of trying to overthrow the state in 1964 and sentenced to life in prison. But even there Mandela fought for justice. His struggle to change South Africa-even from inside prison-became famous across the world. He wrote repeatedly to South African President F.W. de Klerk, asking to talk. With protests growing, the President agreed. For years, De Klerk met with Mandela and other black leaders in secret to talk about how to solve South Africa’s problems.In 1990, De Klerk announced the end of racial segregation. Mandela, then 71 years old, was finally allowed to walk free after spending 27 years prison.In 1993, Mandela, President de Klerk, and other South African leaders wrote a new constitution for the country. This document described a new vision for the nation, and promised equality to all South Africans. The same year, Mandela and De Klerk won the Nobel Peace Prize for their work. Mandela was elected President in the following year, when blacks were allowed to vote for the first time. He served as his country’s f irst black President from 1994 to 1999. After his presidency ended, Mandela continued to fight political and cultural problems he thought were important. To the many, Mandela will always be a symbol for peace, justice, and equality.81. What was the aim of the African National Congress?(No more than 6 words)82. When did Mandela win the Nobel Peace Prize?(No more than 3 words)83. How did Mandela fight for justice when he was in prison?(No more than 12 words)84. What kind of person is Mandela in people’s eyes?(No more than 12 words)SECTION C (25 marks)85.
