2023年深圳市高三年级第二次调研考试 试卷及答案

2023年深圳市高三年级第二次调研考试第二部分阅读第一节AYour Garden EscapeEven in the big city you can find oases (绿洲) of calm and beauty. From a royal palace to a classical garden, we recommend great green spaces to escape the hustle and bustle of London.Horniman GardensHorniman Gardens cover 16 acres with breathtaking views of London. Visitors can enjoy the Sound Garden, Meadow Field, and even a Prehistoric Garden, which features a display of "living fossils."The gardens are very popular with families, and dogs can be let off their leads in the Meadow Field.Chiswick GardenAs a classical garden landscape in London, it was here that the English Landscape Movement was born with William Kent's designs. Enjoy fresh bread, seasonal food, and natural wines in the award-winning cafe,while admiring the beauty of the naturalistic landscape,spotted with impressive art and statues.Buckingham Palace GardenThe 39-acre garden boasts more than 350 types of wildflowers, over 200 trees and a three-acre lake. The garden also provides a habitat for native birds rarely seen in London. A tour of the garden can be completed by having a cream tea in the cafe overlooking the Palace's famous grassland and lake.Kew GardenThe Royal Botanic Garden at Kew is one of the world's most famous gardens and a UNESCO World Heritage Site. Have a walk through the vast garden, spot local wildlife at the lake, or get your hands dirty by trying a gardening lesson. Be sure to visit the Temperate House, which contains some of the rarest and most threatened plants.21. What can visitors do in both Horniman Gardens and Chiswick Garden?A. Study living fossils.B. Taste delicious food.C. Enjoy impressive art.D. Appreciate fine views.22. Where should visitors go if they want to join in hands-on activities?A. Horniman Gardens.B.Chiswick Garden.C. Buckingham Palace Garden.D.Kew Garden.23.What is the purpose of the text?A. To inform visitors of famous gardens.B. To entertain interested garden visitors.C. To stress the necessity of garden escape.D.To show the benefits of touring gardens.BMy childhood was a painted picture of sunny sky and rolling green fields stretching to the horizon. It tasted of sharp berries and smelt of sour grapes. My family lived in a cabin (小木屋) in the countryside but I lived in my mother's arms. They were so delicate but strong, her red hair falling around me like a curtain separating me from the world.Childhood was simple. The borders of my village were the furthest my troubles went and monsters only lived in the pages of books. Every day was a waking dream of running races and muddy knees. My village was archaic , dying cabins housing dying farmers with dying traditions,There weren't many children but me and the other boys; boys of butchers and sellers formed our own group.They called us wild. I suppose we were. Trees and mountains formed our playgrounds and fights broke out as easily as sudden laughter. Liberated from the restrictions of society, we would bound into the woods, deeper and deeper until we found a lake which, with a wild yell, we would jump into all at once.My most vivid memories from boyhood center around that lake. Water shone brightly and the sounds of our screams broke into the outcry from birds. The shock of cold water against sweating skin would wake every nerve in my body and my bare feet would hit the sinking muddy bottom. As we submerged (淹没),time would suspend, movements slowing as bubbles rose around us.I was drowning. I was living. I was living. I was drowning.For timelessness or a second (both felt the same), we would suspend, curl up, and then be forced back out into breathing air.We should have known that it wouldn't last forever. Yet, even under the best circumstances, there's something so tragic about growing up: to have your perspective on the people and life around you change; to always struggle to reach a mirror only to find yourself tall enough to see your reflection one day. And find, a different person staring back out at you.24. What does the underlined word "archaic" mean in paragraph 2?A. Borderless.B. Valueless.C. Old-fashioned.D. Poverty-stricken.25.Why did the author consider himself and other children wild?A.They played in the woods crazily.B. They tricked others purposefully.C.They frequently broke social rules.D.

Environmental problems pose such a major threat to its survival that the International Union for Conservation of Nature (IUCN) upgraded the species' extinction risk status (地位) to vulnerable (脆弱的).Much worse, Dugongs are at risk of losing the protection of the Torres Strait Islanders, who have looked after them historically, hunting them for food sustainably and monitoring their numbers. These native people keep their biodiversity, and have deep knowledge about their environment. But these people are also threatened, in part because rising sea levels are making it difficult for them to live there.This situation isn't unique to Dugongs. A global analysis of 385 culturally important plant and animal species found 68 percent were both biologically vulnerable and at risk of losing their cultural protection.The findings clearly illustrate that biology shouldn't be the primary factor in shaping conservation policy, says anthropologist Victoria Reyes-Garcia. When a culture declines, the species that are important to that culture are also threatened."Lots of conservationists think we need to separate people from nature," says Reyes-Garcia."But that strategy misses the caring relationship many cultural groups have with nature."One way to help shift conservation efforts is to give species a "bio-cultural status,"which would provide a fuller picture of their vulnerability. In the study, the team used a new way to determine a species' risk of disappearing: the more a cultural group's language use declines, the more that culture is threatened. The more a culture is threatened, the more culturally vulnerable its important species are. Researchers then combined a species' cultural and biological vulnerability to arrive at its bio-cultural status. In the Dugong's case, its bio-cultural status is endangered, meaning it is more at risk than its IUCN categorization suggests.This new approach to conservation involves people that have historically cared for them. It can highlight when communities need support to continue their care. Scientists hope it will bring more efforts that recognize local communities' rights and encourage their participation—taking advantage of humans' connection with nature instead of creating more separation.28.What is the relationship between the native people and Dugongs?A.The native people help conserve Dugongs.B. The native people train Dugongs to survive.C. Dugongs ruin the native people's environment.D.Dugongs force the native people to leave home.29.Which statement will Reyes-Garcia probably agree with?A. The protection policy is used incorrectly.B. Culture is connected to species' existence.C. Many groups take good care of each other.D. Conservationists prefer nature over people.30.How is the study method different from previous ones?A. It involves more preservation efforts.B.It relies on the IUCN's classification.C.It highlights the effect of human languages.D.It assesses the biological influence of a species.31.What is the author's attitude towards the latest approach?A.Conservative.B.Favourable.C.Critical.D.Ambiguous.DAdapting to technological advances is a defining part of the 21st-century life. Just two months after being launched in November 2022, OpenAI's ChatGPT has already reached an audience of over 100 million people. While ChatGPT threatens to change writing and writing-related work, the Mesopotamians, who lived 4,000 years ago in a geographical area centered in modern-day Iraq, went through this kind of far-reaching change before us.Ancient Mesopotamia was home to many of civilization's early developments. Its people were world leaders in adapting to technological and cultural changes.They invented the wheel and agriculture, and pioneered advances in mathematics and urbanization. These breakthroughs are reflected in cuneiform(楔形文字) literature, one of the oldest known forms of writing.In its literature, Mesopotamians don't present cultural and technological advances as consistently beneficial. They often represent new technologies being controlled in the service of human conflict and mostly serving the interests of those with high social positions. In some ways, the representation of new technologies in its literature echoes (映现) contemporary concerns about Al: fears of increasing social inequalities and its potential use in information war.In recent years, AI—the newest form of writing —has been used to decipher (破译)the oldest: cuneiform literature. In broader fields, the boundaries of how AI may be used haven't been clearly explained. In January, for example, a top international AI conference banned the use of AI tools for writing scientific papers.Humans have been struggling to invent, use and adapt to technology since our earliest civilizations. But the technology and resulting knowledge are not always evenly distributed. Knowing how we adapted to changing technology in the past helps us more fully understand the human condition and may even help us prepare for the future.32.What does paragraph 2 mainly talk about concerning Mesopotamians?A. Their adaptation to threats.B. Their influences on writing.C. Their contribution to literature.D. Their achievements in civilization.33.What can be inferred about technological advances from paragraph 3?A.They prevent human conflict.B. They bring about hidden dangers.C.They take away people's concerns.D. They lower people's social status.34. What is the current situation of Al according to paragraph 4?A.Its use in literature is popular.B. It is not allowed to finish papers.C. Its range of application is undefined.D. It is not accepted in broader fields.35.Which of the following is a suitable title for the text?A. How People Can Use the Latest TechnologyB. How ChatGPT Will Threaten Writing and WorkC.What AI Will Do by Learning Cuneiform LiteratureD.What History Can Teach Us About New Tech's Impact第二节 (共5小题;每小题2.5分,满分12.5分)阅读下面短文,从短文后的选项中选出可以填入空白处的最佳选项。

2023年深圳市高三第二次调研考试(二模)语文试卷及答案

2023年深圳市高三第二次调研考试(二模)语文试卷及答案

2023年深圳市高三年级第二次调研考试语文一、现代文阅读(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:作为两种最主要、也最具代表性的艺术形式,文学和图像之间既存在对立或相互竞争,也存在合作或相互模仿。

一方面,语词的时间性使其在叙事上,具有图像叙事难以企及的天然优势,而图像的直观性和在场感,不可避免地给文学叙事带来冲击。

另一方面,为了强化叙事效果,两者都会或多或少地受彼方叙事策略的影响,进而突破自身媒介的限制展开故事。

比如,当代小说受图像的影响,突破传统小说的因果线性逻辑和语词叙事的时间性,追求图像的直观性和在场感,从而凸显故事的空间维度,达到不同以往的艺术境界。

文学受图像的影响,首先体现在对故事内容或题材的选取上。

敏锐的现代作家往往会因某幅图像带来的视觉震撼而产生创作冲动,借语词将图像内容部分或整体地转译、再现出来,形成故事从图像到文字的同质异构转化。

鲁迅先生在《示众》中,用细致的语言对看客们围观杀头的情景进行反复刻画。

相比语词解读的私人性,图像解读的公共性创造了一个主客体转换的空间,受众由解读主体变成被解读与被言说的对象。

正是在这个基于图像而创设的空间中,充当看客的、愚钝麻木的同胞给鲁迅带来了强烈的心灵冲击,使他意识到国民劣根性的根深蒂固。

除了直接转译图像内容之外,文学家还注意到图像在唤起知性和强化记忆方面的强势作用。

劳拉·里斯曾将宣传广告语比作“钉子”,而将视觉形象比作“锤子”,指出只有依靠“图像之锤”才能更准确有力地将“产品之钉”嵌入消费者的大脑。

文学创作对颜色、形状等造型艺术的表现媒介加以利用,从而引发受众视觉层面的联想。

鲁迅的小说中有大量对于颜色的运用,如《药》中“红红白白的”破灯笼映照下,老栓从“碧绿的”包中掏出“红黑的”人血馒头,一连串颜色的对比描写形成强烈的视觉冲击,使受众如见其形、如临其境,凸显封建社会的黑暗及人的麻木与愚昧。

此外,文学作品中借助语词来营造场景画面和故事三维空间,也可形成视觉层面的“图像之锤”,使受众产生深刻的体悟和持久的印象。

深圳中学2023年高三语文第二次模拟真题及答案

深圳中学2023年高三语文第二次模拟真题及答案

深圳中学2023年高三语文第二次模拟真题及答案【题目一】阅读下面的文字,按要求作答。

我国古代有很多传统节日,其中清明节是一个很重要的节日。

请你根据上面提供的资料写一篇短文,内容包括:1. 清明节的时间和起源;2. 清明节的传统活动;3. 清明节的现代意义。

清明节是我国的传统节日之一,又称踏青节,每年的公历四月四日或四月五日。

据说古时候,那时已经过了三个清明了,可天未晴,阴雨连绵,农民们为了求一个风调雨顺的好天气,就把每年的这一天定为祭祀祖先的节日,以此祈求祖先庇佑。

所以,清明节的起源有着浓厚的封建迷信色彩。

随着历史的演进,现在的清明节不再只是简单的祭拜祖先,而是丰富多彩的传统活动。

比如,有些地方会邀请专业的道士举行祭祀典礼,全家人合力整顿祖先墓地,清理墓前的杂草,瞻仰祖先的牌位,烧香献花。

此外,还有一些地方会组织踏青郊游、放风筝、踢毽子等庆祝活动。

然而,清明节的现代意义已经超越了传统的宗教追求,凸显人们关注环保、重视亲情的价值观。

清明时节正值春天,大自然万物复苏,是一个适合郊外游玩的好时机。

踏青郊游的习俗,让人们逃离喧嚣都市,亲近自然,感受春天的气息。

同时,清明也是一个族谱文化的重要节点,通过整顿祖先墓地,清扫墓前的杂草,人们更加认识到亲情的珍贵,加深了家庭关系的纽带。

总之,清明节是我国的一个重要传统节日。

不仅有着古老的起源和丰富多彩的传统活动,还具有现代人们关注环保、重视亲情的内涵。

正是这些特点,使得清明节在现代社会仍然保持着广泛的影响力。

【题目二】阅读下面的短文,根据要求完成任务。

请你根据上面提供的资料写一篇小说片段,内容包括以下要点:1. 主人公的外貌特征和性格;2. 主人公的家庭背景和生活环境;3. 主人公面临的困境以及如何解决困境。
