长沙市一中2025届高三月考试卷(二)语文得分:_____________ 本试卷共10页,时量150分钟,满分150分。

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。

材料一中国诗词讲究含蓄,以淡为美。

而英美诗歌则比较奔放,以感情激越为胜。

另外,中国诗词多以歌颂为主,而英美现代诗歌多以揭露为主。

中国诗人或托物言志,或借景抒情,永远把自己的情感埋藏于诗词之中,我们只有通过“感悟”才可能感觉出其美,最突出的例子莫过于马致远的《天净沙·秋思》。

他几乎没有用一个表达感情的词语,只是把“枯藤”“老树”“昏鸦”简单地排列在一起,寥寥几笔便勾勒出一幅凄凉寂寥的景象,后面两句把几种事物列在一处,却恰如其分地渲染了寂寞、惨淡的气氛,“夕阳西下”更是给整幅画面涂上了一层昏黄的颜色,最后一笔带出“断肠人在天涯”,感觉上前后好像并无直接联系,但感情是连贯的,思路也是连贯的。

一口气读下来,仿佛自己就是诗人所描绘的画中的游子,引起强烈的共鸣。

然而几种事物的并列,虽然没有任何的主观感情,却比再多的语言都要强烈地表达了一种孤寂凄清的感情,这正是中国古典诗歌的魅力所在。

相比之下,英美现代诗歌强调写资本主义社会中畸零人的心理,比较直率地把诗人的所要表达的意思表现出来,直抒胸臆而毫无造作,言尽而意亦尽,回味的空间相对缩小了,但这样比较符合西方人的心理特征、思维特征。

(摘编自吕洋《中西方诗歌比较》)材料二①与中国古典诗歌弱化主体的倾向不同,西方诗歌中的主体差不多总是在场的。

以十四行诗为例,主体总是堂而皇之地出现在诗中,站出来讲话。

这样,西方诗歌就形成了与中国诗歌迥然不同的风格。

②诗歌的风格离不开其文化土壤。

在中国,流行的思想是人与自然的和谐,这种观念的形成与中国人的生活方式和生活环境有关。

早在新石器时代,农业经济就已经建立起来。

几千年来,自给自足的经济稳定繁荣,因此,人们非常依赖自然环境,对自然世界的任何微妙变化都很敏感,他们渴望与自然亲密接触。

炎德·英才大联考雅礼中学2025届高三月考试卷(一)语文本试卷共四道大题,23道小题,满分150分。

时量150分钟。

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:积极情绪(Positive Emotion)可以定义为正面的情绪或者具有正面向上价值的情绪。

情绪的认知理论认为,“积极情绪就是在目标实现过程中取得进步或得到他人积极评价时所产生的感受。

”由此可见,积极情绪就是经历了内在、外在的刺激,正确地解决了问题,达到某种成功与满意度,满足了个体的需求,感觉到个体的存在价值伴有随之而来的愉悦的心情与感受。

积极情绪并不是消极接受、坦然享受、乐不思蜀的感觉。

这些只是浅薄的感受,即时地享乐。

积极情绪拓展到更深的层面——从欣赏到热爱。

它并不是简单的迷恋,而是一种真心喜欢、经过努力而获得的欢愉、欣喜。

“积极情绪”这个词,指向了重要的人性瞬间。

那些轻微而短暂的愉悦状态,其实要比你想象的强大得多。

作为人类,生来就能够体验到微弱短促却愉悦舒畅的积极情绪。

它有着不同的形态和滋味。

回想一下,当感到与他人或与所爱的人心灵相通时;当感到有趣、有创意或忍俊不禁时;当感到自己的灵魂被蕴含在生命中的纯粹的美所打动时;或者当因一个新颖的主意或爱好而感到活力无限、兴致勃勃时,你都会不由自主地产生爱、喜悦、感激、宁静、兴趣和激励这样的积极情绪,它们会打开你的心扉。

然而,无论是迷恋、欢笑还是爱,你由衷的积极情绪总是无法持续很长的时间。

良好的感觉来了又去,就如同好天气一样,这是人类的本性。

积极情绪会逐渐消退,如果它长盛不衰,人们会很难适应变化,无法觉察到好消息和坏消息之间的差异,或是邀请与冒犯之间的差异。

如果你想重塑生活,让它变得更美好,秘诀就是不要把积极情绪抓得太紧,也不要抗拒它稍纵即逝的本性,而是将它更多地植入生活——久而久之,你就会提高积极情绪的分量。

我们发现,在这一秘诀中最重要的是积极率,这是用来描述积极情绪与消极情绪的数量关系的一种方法。

一、现代文阅读(34分)(一)现代文阅读Ⅰ(本题共5小题,18分)阅读下面的文字,完成1~5题。

(一)①因为儒家政治构想的最高目标是旨在修身齐家治国平天下的“人”,人与人之间伦理认同即是根本和逻辑起点。

这种伦理的内涵,有着更为普遍和更为基础的对天下之“人”的论述。

先秦时期的中国,以最为根本性的孝、仁来建构人与人的认同,来建构自己与“他者”共在的联系,即天下。

②周朝的天下,以宗法制为联结,宗法制的伦理根基是“孝”。

家庭共同体有了孝的概念,孝的延伸就是天下共同体之“仁”。

仁不是与他者的对立,而是与他者的共生共通。

“仁”即是处理人与人关系的概念,处理人与人之间关系,逻辑上首先要处理与亲人的关系。

只有实现家庭内部的“亲亲”,才能实现向外的“爱人”。

人与家庭共生,通过“仁”的概念转向了人与天下共生。

因此理想的天下就是“不独亲其亲,不独子其子”。

天下大同,是仁孝概念的逻辑必然,也是伦理化天下的根本内涵。

换句话说,天下其实就是人类的伦理共同体,因此在这个共同体之内,就不可能有民族歧视。

③天下为一家,意味着“他者”的取消,即不以政体或民族区分敌我,而是在伦理关系中确证对方的独立性,并与对方共生共在。

天下一家的秩序展现在现实中,就是以伦理关系为核心的礼制。

凡天下之人,皆需仁孝,而仁孝就要服从礼制,服从礼制就要服从天子。

因此,家与天下就在政治秩序层面实现了同构。

随着大一统的实现,天下之内没有了其他的国,国家秩序也就成了天下秩序。

这种伦理化的天下秩序不断将边缘的地域和人民纳入天下中来,荀子说:“四海之内若一家,通达之属莫不从服。

”④后世的中国人,往往不是以民族或者国家来定义中国,而是以文化或文明定义中国。

正是因为中国概念的文明内涵,才导致中国可以消弭地理边界,逐渐与天下趋同。

⑤这种伦理的、文化的天下观念在宋朝受到了某种程度的挑战。

A. happy B. rich C. alone D. aliveIV.Reading Comprehension (35 points)Directions: Read the following passages. Each passage is followed by five questions or unfinished statements. For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)A four-year-old girl is lying in the arms of a doctor. She has just become motherless. Her pink clothes are bloodied and her eyes stare at something only she can see. She has suffered from a bombing near her home in southern Iraq.Every day we see images like this on our televisions. We see young Iraqi children begging for food and water from American and British soldiers as they move through towns and cities towards the capital, Baghdad. We see these children following grown-ups, carrying bags of belongings almost the same size as their small bodies as they flee their homes in Baghdad.They represent just some of the young lives that have been turned upside down by the ongoing war. And they show the terrible price being paid by Iraqi children.“Dad, why are the Americans striking us? Are we going to be killed?” asks the son of Abu Sinar, an Iraqi engineer. Abu finds it hard to explain this war to his eight-year-old son.He tries to comfort him by saying: “The bombs are far away from us. The American s are fighting the soldiers. We‟re going to be all right.” Even though Abu knows this isn‟t always the truth.In southern parts of the country, like Iraq‟s second largest city, Basra, the United Nations International Children‟s Emergency Fund is working to repair the damage caused by fighting. The organization is working to provide clean water and restore electrical power, said Geoffrey Keele, a UNICEF spokesman.But little else can be done. In Baghdad, parents give their children sleeping pills to try and let them escape the sound of exploding bombs. And all the schools are closed.“All they can do is listen to and hear the war,” said Keele. “There is suffering inBaghdad. It is clear that the bombing is affecting the mental well-being of the children.”Des pite UNICEF‟s efforts, dirty water is being blamed for cholera outbreaks in southern Iraq. Diarrhea is spreading among the children, sometimes leading to death.Nearly 50 percent of Iraq‟s population is under 15 years old. And 30 percent of them already suffered before the war from malnutrition, according to international aid organizations.Now the situation is worse, but continual fighting makes it impossible to count the number who are hungry, sick, injured or even dead.65.The underlined word diarrhea” in the last paragraph but two must be _______A. a kind of horrendous foodB. a kind of infectious diseaseC. a new toyD. a piece of terrible news66. Parents give their children sleeping pills _________.A. to get rid of the terrible sound of exploding bombsB. to help children to go to sleep because they are very tiredC. in case their children should be frightened by the sound of exploding bombsD. so that their children would not have their hearing harmed67. What is the writer‟s attitude toward s Iraqi people in this article?A. The writer loves only the children of Iraq.B. The writer wants to know more about how many people will go hungry or even die.C.The writer shows sympathy for Iraqi people.D. The writer will help Iraqi people to get over any difficulty(B)Creativity is the key to a brighter future, say education and business experts. Here is how schools and parents can encourage this important skill in children.If Dick Drew had listened to his boss in 1925, we might not have a product that we now think of as of great importance: a new type of tape. Drew worked for the Minnesota Mining company. At work he developed a kind of material strong enough to hold things together. But his boss told him not to think more about the idea. Finally, using his own time, Drew improved the tape, which now is used everywhere by many people. And his former company learned from its mistake. Now it encourages people to spend 15 percent of their work time just thinking about and developing new ideas.Creativity is not something one is just born with, nor is it necessarily a character of high intelligence. The fact that a person highly intelligent does not mean that he uses it creatively. Creativity is the matter of using the resources one has to produce new ideas that are good for something. Unfortunately, schools have not tried to encourage creativity. With strong attention to test results and the development of reading, writing and mathematical skills, many educators give up creativity for correct answers. The result is that children can give back information but can not recognize ways to use it in new situations. They may know the rules correctly, but they are unable to use them to work out practical problems.It is important to give children choices. From the earliest age, children should be allowedto make decisions and understand their results. Even if it‟s choosing between two food items for lunch, decision-making helps thinking skills. As children grow older, parents should let their children decide how to use their time or spend their money, but not help them too much if they make the wrong decision. The child may have a hard time, but that is all right. This is because the most important character of creative people is a very strong desire to find a way out of trouble.68. What did the company where Drew once worked learn from its mistake?A.They encouraged people to work a longer time.B.They discouraged people from thinking freely.C.They asked people to spend all their work time developing new ideas.D.They encouraged people to spend some of their work time considering and improvingnew ideas.69.Creativity is something __________.A.that people are born withB.that depends on intelligenceC.that is a way of using what one has learned to work out new problemsD.that is not important at all70. What should the parents do when their children decide how to spend their money?A.Try to help them as much as possible.B.Take no notice of whatever they do.C.Help them if their decision is wrong but not too much.D.Leave them as they are.71. This passage mainly deals with the question of __________.A.what is the key to a brighter futureB.what creativity isC.how schools and parents can encourage creativity in childrenD.whether schools and parents should allow children to make choices and decisions(C)Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country and how tourism affects them. Tourism should help a country keep the customs and beauty that attract tourists. Tourism should also advance the well-being (health and happiness) of local inhabitants.Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country‟s economy can suffer.On the other hand, if there is not enough tourism, people can lose jobs. Businesses canalso lose money. It costs a great deal of money to build large hotels, airports, air terminals, first-class roads, and other support facilities needed by tourist attractions. For example, a major international-class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money.Building a hotel is just a beginning. There must be many support facilities as well, including roads to get to the hotel, electricity, sewers (阴沟) to handle waste, and water. All of these support facilities cost money. If they are not used because there are not enough tourists, jobs and money are lost.72.Which of the following has most probably been discussed in the paragraph that goesbefore the passage?A.It is extremely important to develop tourism.B.Building roads and hotels is essential.C.Support facilities are highly necessary.D.Planning is of great importance to tourism.73.Too much tourism can cause all these problems EXCEPT ___________.A. a bad impact on other industriesB. a change of tourists‟ customsC.overcrowdedness of places of interestD.pressure on traffic74. It is good for local people to be well aware that tourism will __________.e up a large amount of waterB.weaken their economyC.help establish their traditionsD.help improve their life75. The word handle in the last paragraph most probably means “__________”.A. carry awayB. pick upC. get inD. take down(D)Olaf Stapledon wrote a book called First and Last Men, in which he looked millions of years ahead. He told of different men and of strange civilizations , broken up by long …dark ages‟ in between. In his view, what is called the present time is no more than a moment in human history and we are just the First Men. In 2,000 million years from now there will be the Eighteenth or Last Men.However, most of our ideas about the future are really very short-sighted . Perhaps we can see some possibilities for the next fifty years. But the next hundred ? The next thousand? The next million ? That‟s much more difficult.When men and women lived by hunting 50,000 years ago, how could they even begin to picture modern life? Yet to men of 50,000 years from now, we may seem as primitive in our ideas as the Stone-Age hunters do to us. Perhaps they will spend their days gollocking to make new spundels, or struggling with their ballalators through the cribe. These words, which I have justmade up, have to stand for things and ideas that we simply can‟t think of.So why bother even to try imagining life far in the future? Here are two reasons. First, unless we remember how short our own lives are compared with the whole human history, we are likely to think our own interests are much more important than they really are. If we make the earth a poor place to live on because we are careless or greedy or quarrelsome, our grandchildren will not bother to think of excuses for us.Second, by trying to escape from present interests and imagine life far in the future, we may arrive at quite fresh ideas that we can use ourselves. For example, if we imagine that in the future men may give up farming, we can think of trying it now. So set your imagination free when you think about the future.76. A particular mention m ade of Stapledon‟s book in the opening paragraph _______.A.serves as a description of human historyB.serves as an introduction to the discussionC.shows a disagreement of viewsD.shows the popularity of the book77. The text discusses men and women 50,000 years ago and 50,000 years from now in order toshow that _______.A.human history is extremely longB.life has changed a great dealC.it is useless to plan for the next 50 yearsD.it is difficult to tell what will happen in the future78. Spundels and ballalators are used in the text to refer to ______.A.tools used in farmingB.ideas about modern lifeC.unknown things in the futureD.hunting skills in the Stone Age79. According to the writer of the text, imagining the future will _____.A.serve the interests of the present and future generationsB.enable us to better understand human historyC.help us to improve farmingD.make life worth living(E)给下面的文章配上小标题;80. ________ Crime has its own cycles, a magazine reported some years ago. Police records that were studied for five years from over 2,400 cities and towns show a surprising link between changes in the season and crime patterns.81. _______The pattern of crime has varied very little over a long period of years. Murder reaches its high during July and August, and so do other violent attacks. Murder, moreover, is more than seasonal: it is a weekend crime. It is also a nighttime crime: 62 percent ofmurders are committed between 6 p.m. and 6 a.m.82. ________Unlike the summer high in crimes of bodily harm, burglary(盗窃) has adifferent cycle. You are most likely to be robbed between 6 p.m. and 2 a.m. on a Saturday night in December, January, or February. The most uncriminal month of all? May -- except for one strange statistic. More dog bites are reported in this month than in any other month of the year.83. ________ Apparently our intellectual seasonal cycles are completely different from ourcriminal tendencies. Professor Huntington, of the Foundation for the Study of Cycles, made extensive studies to discover the seasons when people read serious books, attend scientific meetings and make the highest scores on examinations. In all instances, he founda spring peak and an autumn peak separated by a summer low. On the other hand,Professor Huntington's studies indicated that June is the peak month for suicides(自杀) and admissions to mental hospitals. June is also a peak month for marriages!84. _________ Possibly, high temperature and high humidity(湿度) bring on our strangeand terrifying summer actions, but police officials are not sure. "There is, of course, no proof of a connection between humidity and murder," they say, "Why murder‟s high time should come in the summertime we really don't know."A.Patter of murderB.Intellectual seasonal cyclesC.Cycle of crimeD.Possible explanationsE.Other patters of crimeF.Ways to avoid crime第二卷(共45分)I.Translations1.他有可能来参加下周举行的晚会吗?( chance )2.正是由于他未能在恰当的时候澄清这一误会他该受到责备。
