The Zhou royal court had a specialized department called “ice administration”. They collected natural ice blocks each December to store in the icehouse. During the Qing Dynasty, “ice tickets” were used and they were available only to officials and the rich. Ice container The most commonly used cooling tool is called “Jian”, which is a big container filled with ice. It was made of clay in early Chinese history, and was later made of copper (铜). The “Jian” can be seen as an ancient refrigerator, which can be used to make cold drinks. Hiding food in the well During the Qin and Han dynasties, for common people, the most common way to cool off is by using their wells. Some families put a pot in the well as a cold closet, or put food in a basket and lowered the basket into the well with a rope. Herbal drinks During the Qing Dynasty, taking Chinese herbal medicine was popular in Beijing. In hot summer, some people preferred to drink ice water, some boiled perilla leaves, and liquorice as summer soup to keep off the heat. Ancient people also loved to make lotus seed soup in summer for the benefit of strengthening the body. 1.What does “Jian” have the same function as? A. Container. B. Refrigerator. C. Clay. D. Copper. 2.Which of the following is unavailable to common people? A. Ice tickets. B. Ice container. C. Hiding food in the well. D. Herbal drinks. 3.What’s the common purpose of the above four ways? A. To strengthen the body. B. To keep food fresh. C. To escape the summer heat. D. To make cold drinks. 答案与解析　 本文是一篇说明文。文章简要介绍了古代人在炎炎夏日的避暑方略。 1.B　 细节理解题。从文章第二段“The ‘Jian’ can be seen as an ancient refrigerator, which can be used to make cold drinks. (‘Jian’可以被视为一种古老的冰箱,可以用来制作冷饮。)”可知,“Jian”与现在的冰箱用途一样。故选B项。 2.A　细节理解题。从文章第一段“During the Qing Dynasty, ‘ice tickets’ were used and they were available only to officials and the rich. (在清朝,‘冰票’被使用,并且只对官员和富人开放。)”可知,在古代普通人无法得到冰票。故选A项。 3.C　细节理解题。由小标题“Icehouse and ice ticket (冰屋和冰票)”,“Ice container (放冰容器)”,“Hiding food in the well (把食物藏在井里)”,和文章最后一段“During the Qing Dynasty, taking Chinese herbal medicine was popular in Beijing. In hot summer, some people preferred to drink ice water, some boiled perilla leaves, and liquorice as summer soup to keep off the heat. Ancient people also loved to make lotus seed soup in summer for the benefit of strengthening the body. (在清朝,服用中草药在北京很流行。在炎热的夏天,一些人喜欢喝冰水,一些煮熟的紫苏叶和甘草作为夏天的汤来避暑。古人也喜欢在夏天做莲子汤,以强身健体。)”以及结合上面内容可知,本文主要讲述了古人是如何避暑的,A、B和D选项只是其中一种或两种方略的目的,不能以偏概全。故选C项。 阅读　B　(2024·成都外国语学校模拟)　体裁:说明文　主题语境:太空探索　难度:★★★☆☆ 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　The surface of Mars is etched with ancient river valleys and lake basins. Some researchers think that liquid water once flowed on the Red Planet. Today, Mars is too cold for much, if any, liquid water to exist. And 3.8 billion years ago, when the flowing water formed, the sun was fainter than it is today, making it even harder to imagine a warm Martian climate. That’s why many researchers think Mars may have gone in and out of deep freezes. Some researchers have suggested that early Mars only thawed out when large asteroid impacts or volcanic eruptions temporarily warmed the planet. But Kasting, a geologist at Penn State University, thinks warm windows from such dramatic events would have been too brief to carve the vast canyons that exist on Mars. Now, Kasting and his colleagues have come up with an alternative explanation. They think Mars may have experienced a series of climate cycles caused by changes in the strength of the greenhouse effect. The idea goes like this: When Mars was cold and frozen, volcanoes continued to belch out the greenhouse gases like carbon dioxide and hydrogen into the atmosphere. There, the gas blanket trapped heat and warmed the planet up until liquid water began to flow, forming Mars’ rivers and lakes. However, warm temperatures and abundant water would also have sped up certain chemical reactions that consumed carbon dioxide, reducing the greenhouse effect and cooling the planet back down again. Then the cycle would repeat. Kasting shared his theory with other astronomers at the December meeting of the American Geophysical Union in San Francisco, and in the journal Earth and Planetary Science Letters. So far, Kasting’s team has only shown that such an explanation is possible, according to climate models. But the researchers say field trips could help test the idea by looking for evidence of multiple warm events, and their durations. 4.What made researchers believe that liquid water once existed on Mars? A. The surface of Mars is with liquid water. B. The temperatures of the sun. C. The geological features of Mars. D. The faintness of the sun. 5.What is Kasting’s theory based on? A. Large asteroids had no impact on Mars. B. Deep valleys couldn’t be formed in a short period of time. C. Volcanic eruptions were very frequent on Mars. D. Carbon dioxide and hydrogen were abundant in the atmosphere. 6.What do we know about the climate cycles? A. Carbon dioxide and hydrogen would not be changed. B. The greenhouse gases played an important role in this cycle. C. The climate cycles would be experienced three times in total. D. Hot environment and a large amount of water would accelerate certain chemical reactions to generate carbon dioxide. 7.Which is the most suitable title for the text? A. Climate Cycles Could Have Carved Canyons on Mars B. Large Asteroid Impacts on the Red Planet C. Liquid Water Existing on Mars D. Ancient River Valleys Have Been Found on Mars 答案与解析　 本文是一篇说明文。火星上曾经有液态水,这是怎么形成的呢?科学家们提出了新的理论。 4.C　细节理解题。根据第一段的“The surface of Mars is etched with ancient river valleys and lake basins. Some researchers think that liquid water once flowed on the Red Planet. (火星表面蚀刻着古老的河谷和湖泊盆地。一些研究人员认为液态水曾经在这颗红色星球上流动)”可知,火星表面有着古老的河谷和湖泊盆地,这些地质特征使得研究人员认为液态水曾经在火星上存在。故选C项。 5.B　推理判断题。根据第二段的“But Kasting, a geologist at Penn State University, thinks warm windows from such dramatic events would have been too brief to carve the vast canyons that exist on Mars. (但是宾夕法尼亚州立大学的地质学家Kasting认为,这种突然事件打开的温暖窗口期太短暂了,无法蚀刻出火星上存在的巨大峡谷)”可知,宾夕法尼亚州立大学的地质学家卡萨丁认为这种突然事件打开的温暖窗口期太短暂了,无法形成火星上存在的巨大峡谷。由此推知,卡萨丁的理论是建立在深谷不可能在短时间内形成的理论上的。故选B项。 6.B　细节理解题。根据第三段“The idea goes like this:When Mars was cold and frozen, volcanoes continued to belch out the greenhouse gases like carbon dioxide and hydrogen into the atmosphere. There, the gas blanket trapped heat and warmed the planet up until liquid water began to flow, forming Mars’ rivers and lakes. (这个想法是这样的:当火星寒冷冻结时,火山继续向大气中喷射二氧化碳和氢气等温室气体。在那里,气层捕获热量并使行星升温,直到液态水开始流动,形成了火星的河流和湖泊)”可知,温室气体在这个循环中起了重要作用。故选B项。 7.A　主旨大意题。通读全文,结合第二段“They think Mars may have experienced a series of climate cycles caused by changes in the strength of the greenhouse effect. (他们认为火星可能经历了一系列由温室效应强度变化引起的气候周期)”和第三段“The idea goes like this: When Mars was cold and frozen, volcanoes continued to belch out the greenhouse gases like carbon dioxide and hydrogen into the atmosphere. There, the gas blanket trapped heat and warmed the planet up until liquid water began to flow, forming Mars’ rivers and lakes. (这个想法是这样的:当火星寒冷冻结时,火山继续向大气中喷射二氧化碳和氢气等温室气体。在那里,气层捕获热量并使行星升温,直到液态水开始流动,形成了火星的河流和湖泊)”可知,文章介绍了科学家提出的关于火星上的河谷和湖泊盆地形成原因的最新理论,研究指出可能是气候的变化周期造就了如今火星上可观测到的峡谷和河床等地理特征。由此可知,“Climate Cycles Could Have Carved Canyons on Mars (气候周期可能在火星上雕刻了峡谷)”是最佳标题。故选A项。 教师备选资源 （阅读C、D） 阅读　C　(2023·浙江首考)　体裁:说明文　主题语境:现代技术　难度:★★★★☆ 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　A machine can now not only beat you at chess, it can also outperform you in debate. Last week, in a public debate in San Francisco, a software program called Project Debater beat its human opponents, including Noa Ovadia, Israel’s former national debating champion. Brilliant though it is, Project Debater has some weaknesses. It takes sentences from its library of documents and prebuilt arguments and strings them together. This can lead to the kinds of errors no human would make. Such wrinkles will no doubt be ironed out, yet they also point to a fundamental problem. As Kristian Hammond, professor of electrical engineering and computer science at Northwestern University, put it: “There’s never a stage at which the system knows what it’s talking about.” What Hammond is referring to is the question of meaning, and meaning is central to what distinguishes the least intelligent of humans from the most intelligent of machines. A computer works with symbols. Its program specifies a set of rules to transform one string of symbols into another. But it does not specify what those symbols mean. Indeed, to a computer, meaning is irrelevant. Humans, in thinking, talking, reading and writing, also work with symbols. But for humans, meaning is everything. When we communicate, we communicate meaning. What matters is not just the outside of a string of symbols, but the inside too, not just how they are arranged but what they mean. Meaning emerges through a process of social interaction, not of computation, interaction that shapes the content of the symbols in our heads. The rules that assign meaning lie not just inside our heads, but also outside, in society, in social memory, social conventions and social relations. It is this that distinguishes humans from machines. And that’s why, however astonishing Project Debater may seem, the tradition that began with Socrates and Confucius will not end with artificial intelligence. 8.Why does the author mention Noa Ovadia in the first paragraph? A. To explain the use of a software program. B. To show the cleverness of Project Debater. C. To introduce the designer of Project Debater. D. To emphasize the fairness of the competition. 9.What does the underlined word “wrinkles” in Paragraph 2 refer to? A. Arguments. B. Doubts. C. Errors. D. Differences. 10.What is Project Debater unable to do according to Hammond? A. Create rules. B. Comprehend meaning. C. Talk fluently. D. Identify difficult words. 11.What can we learn from the last paragraph? A. Social interaction is key to understanding symbols. B. The human brain has potential yet to be developed. C. Ancient philosophers set good examples for debaters. D. Artificial intelligence ensures humans a bright future. 答案与解析　 本文是一篇说明文。文章主要介绍了在辩论中战胜人类的名为Project Depater的软件程序。 8.B　推理判断题。通读第一段内容可知,文章第一段提到以色列前国家辩论冠军Noa Ovadia是为了说明Project Debater在辩论方面比人类出色,故B项“为了展示Project Debater的聪明”为正确选项。故选B项。 9.C　词义猜测题。根据画线词的前一句“This can lead to the kinds of errors no human would make.”可知,wrinkles指代errors。故选C项。 10.B　细节理解题。根据第二段段尾的“There’s never a stage at which the system knows what it’s talking about.”以及第三段段首的“What Hammond is referring to ... the most intelligent of machines.”可知,根据Hammond的说法,Project Debater做不到的是理解意义,故选B项。 11.A　细节理解题。最后一段聚焦“意义的产生”,指出意义是通过社会互动生成的,而非计算。赋予意义的规则不仅存在于我们的大脑中,而且也存在于外部,存在于社会中,存在于社会记忆、社会习俗和社会关系中。这也将人类和机器区分开来,无论Project Debater看起来多么令人震惊,从苏格拉底和孔子开始的传统不会因为人工智能而结束。故社会互动是理解符号的关键。故选A项。 阅读　D　(2024·洛阳高三月考)　体裁:议论文　主题语境:学校教育　难度:★★★☆☆ 　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　 　　High school biology teacher Kelly Chavis knew smartphones were a problem in her class. But not even the students realized how much of a problem the devices were until Chavis did an in-class experiment. For one class period, students used a whiteboard to count every Snapchat, Instagram, text, call that appeared on their phones.Chavis is among a growing number of teachers, parents and health experts who believe that smartphones are now partly to blame for increasing the levels of student anxiety. “One girl, just during the one hour, got close to 150 Snapchat notifications. 150!” she said. Jean Twenge, a psychology professor at San Diego State University in California, said it is not a coincidence that youth mental health issues have risen with the number of phones. “This use of phones has led to a loss of sleep and face-to-face interactions necessary for their growth,” she said. Researchers are still not sure whether phones cause student depression or depression causes phone use. But nearly 60 percent of parents said they worry about the influence of social media on their child’s physical and mental health. Both schools and parents are starting to take steps to deal with the problem. Many public schools pay outside companies to watch students’ social media activity for signs of anxiety. Other schools invite in yoga teachers and comfort dogs to help calm students. 12.What’s the purpose of Chavis’s experiment? A. To see how many students have smartphones. B. To find out how popular her students are. C. To show smartphones influence teenagers greatly. D. To tell her students how to use smartphones wisely. 13.How did Kelly Chavis feel about the result? A. Shocked. B. Excited. C. Satisfied. D. Frightened. 14.Which of the following is true according to Jean Twenge? A. Students are now under great stress. B. Students spend too much money on smartphones. C. Over-using phones causes drops in students’ grades. D. Over-using phones may harm students’ body and mind. 15.What might be talked about if the passage is continued? A. How other schools deal with students’ phones. B. Whether the ways to handle phones are effective. C. How some parents deal with their children’s phones. D. Whether students are willing to give up using phones. 答案与解析　 这是一篇议论文。作者通过Kelly Chavis的课堂实验展示了智能手机对学生的影响,并引用一些专业人士的观点来支持个人的论证,继而说明了学校就学生使用手机问题采取的措施。 12.C　细节理解题。根据第一段的“But not even the students realized how much of a problem the devices were until Chavis did an in-class experiment.”和下文可知,直到查维斯在课堂上做了一个实验,学生们才意识到这些设备有多大的问题:焦虑、睡眠不足等问题,故查维斯的实验目的是想去展示手机对青少年的影响很大。故选C项。 13.A　推理判断题。根据第二段的“Chavis is among a growing number of teachers ... are now partly to blame for increasing the levels of ... ‘One girl, just during the one hour, got close to 150 Snapchat notifications. 150!’ she said.(越来越多的老师、家长和健康专家认为,学生的焦虑程度越来越高,部分原因是智能手机造成的,查维斯就是其中之一。‘一个女孩在一个小时内收到了近150条Snapchat通知。150条!’)”可知,Chavis对于实验的结果是非常震惊的。故选A项。 14.D　推理判断题。根据第三段的“it is not a coincidence that youth mental health issues have risen with the number of phones”可知Jean Twenge认为过度使用手机可能会伤害学生的身心。故选D项。 15.C　推理判断题。根据最后一段的第二、三句“Many public schools ... to help calm students.”可知,最后一段讨论的是学校应采取的措施,那么接下来的段落可能会讨论的问题是一些父母如何处理他们孩子的手机。故选C项。 七选五　体裁:说明文　主题语境:生活态度　难度:★★☆☆☆ 　　Conscious (有意识的) living is not just a trend. 　1　 It is about being intentional with everything you do—your words, actions, beliefs, habits, and choices. Accepting conscious living takes some effort, but it is worthwhile. Here are some ways you can achieve this goal.  ·Be conscious about your time. Time is the most precious thing because there is no way to live a moment again. The way you spend your time determines the course of your life. If you waste your precious hours doing negative things, you will regret it later. The first step for living consciously is to be wise about your time. 　2　  ·Know yourself better. You cannot achieve them unless you understand your needs and intentions. 　3　 Spend time thinking over and knowing your strengths and weaknesses. Once you know yourself better, you can create a plan to work towards becoming more patient, honest, and forgiving.  ·Learn to be grateful. Gratitude takes you a long way towards conscious living. It opens you up to a happier and a fulfilled mindset. Most people are unhappy because they see only the negatives in life. However, everyone has something to be grateful for. Writing a gratitude journal is a good start for counting your blessings. 　4　  ·Believe in yourself. It is the key to making the right choices, yet not regretting the wrong ones. The best way to build self-belief is by reflecting on your own thoughts. 　5　 Care for it and follow it to make it stronger down the line.  Conscious living is a skill you need to learn as you go, so be willing to make the effort and master it. You will absorb it soon and be a happier person in the long run. A. Accept the person you are. B. Life can be a lot better with the right decisions. C. It is a healthy choice that enables you to be happy. D. Pick it as a daily habit, and you will notice the difference. E. Be selective about things you spend it on, and allocate it for positive activities. F. It is easier said than done because most people fail to make an effort to know themselves. G. Spending time alone and thinking deeply are effective measures that enable you to identify the inner voice. 答案与解析　 本文是一篇说明文。清醒的生活不仅仅是一种趋势,它是一个健康的选择,能让你快乐。本文对如何进入清醒的生活状态给了几个建议。 1.C　根据上文“Conscious (有意识的) living is not just a trend.
