Smart farming refers to using modern technology to help farmers grow food more easily and efficiently. It can solve many problems in traditional farming and improve agricultural production (农业生产) efficiency greatly. Sensors (传感器) are key tools in smart farming. These small tools can be put into the soil to monitor water and temperature exactly. Farmers can check these data on their mobile phones at any time, which helps them decide the best time to water the crops. This not only ensures the healthy growth of crops but also avoids water waste. Drones (无人机) will also play an important role in future farming. They can fly over farmland to take clear photos of crops. Farmers can judge whether the crops are healthy or sick with diseases by analyzing these photos. Some advanced drones can even spray fertilizer (肥料) and pesticides (杀虫剂) evenly, which saves a lot of time and labor compared with traditional manual work. In addition, smart farming will apply AI (Artificial Intelligence). AI can analyze a large amount of data, including weather conditions and soil quality, to tell farmers the optimal time for planting and harvesting. With AI’s help, farmers can get higher yields with less work, which is very important for meeting the food demand of the growing world population. 1．What can sensors do in smart farming? A．Take clear photos of crops. B．Check soil water and temperature exactly. C．Spray fertilizer and pesticides evenly. D．Analyze weather and soil data. 2．How can drones help farmers? A．They can help farmers water crops. B．They can put sensors into the soil. C．They can help farmers judge if crops are sick. D．They can analyze soil quality. 3．What does the underlined word “optimal” in Paragraph 4 probably mean? A．Early. B．Long. C．Late.

He learnt to fly a plane before he could even drive a car! He took flying lessons with his dad in a flying club. After about a year of lessons, Lucien got his pilot’s licence (执照). With the licence, he could fly a small plane all by himself. His first solo flight happened on the day he turned 14. It is very unusual for someone that young to fly a plane alone. Lucien’s dad, Marco Distler, always wanted to become a pilot. During a family trip to an air show, he joked, “It would be funny if you became a pilot at 14.” To his surprise, Lucien loved the idea a lot. Then they decided to start lessons together. During training, Lucien and his dad learnt a lot about flying, including aerodynamics (空气动力学), how to use a pilot’s radio (无线电), and how to take off and land a small plane. Lucien learnt quickly and passed two exams to get his licence. He even scored higher than his dad on the written test. When Lucien flew the plane alone for the first time, he took off, flew, and landed safely in seven minutes. He said he was not scared or stressed at all. “The plane felt lighter without anyone beside me, and I enjoyed making radio calls,” he said. His dad, on the other hand, said he felt nervous about Lucien’s flight. But he was really proud of his son. Lucien does not know if he will be a professional (职业的) pilot, but he wants to keep learning. He also looks forward to getting a driver’s licence and believes he can achieve anything with practice and confidence. 6．What does the underlined word “solo” in Paragraph 2 probably mean? A．Safe. B．Slow. C．Single. D．Skilled. 7．What inspired Lucien to learn to fly a plane? A．A movie about pilots. B．A joke from his father. C．A lesson in a flying club. D．A plane trip with his family. 8．How did Lucien feel during his first flight? A．He felt scared and nervous. B．He felt relaxed and enjoyed it. C．He felt stressed but stayed calm. D．He felt lonely but proud of himself. 9．Which of the following can best describe Lucien? A．Polite and smart. B．Honest and polite. C．Smart and hard-working. D．Hard-working and honest. 10．What can we learn from the text? A．Hard work can bring good luck. B．Having a partner makes learning more fun. C．Even a small change can make a big difference. D．You’re never too young to achieve something big. （三） Can you say the meaning of “zero”? Can you do addition and subtraction (加减法)? Most people can. But do you know bees can do these things too? A study shows that bees have even greater maths abilities. After some training, they can know the difference between even numbers and odd numbers. Some Australian scientists put up different cards with an odd (奇数的) or even (偶数的) number of triangles (三角形). They used the numbers 1 to 10. Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers. If a bee flew to the right card, it would get sweet water. If it chose the wrong card, it got bitter (苦的) water. In a short time, all the bees knew what odd numbers or even numbers were. They could fly to the right numbers 80% of the time. After that, the scientists added new cards with the numbers 11 and 12. The bees never saw the numbers in their training before, but they could choose rightly 70% of the time. Surprisingly, the bees even learned odd numbers more quickly than people. How did the bees learn the numbers so fast? Scientists didn’t have a clear idea. But they believe if they find the answer, it will help them build better and faster computers. After all, a bee’s brain is about 86,000 times smaller than ours! 11．How does the writer start the passage? A．By listing facts. B．By giving examples. C．By asking questions. D．By using pictures. 12．Which of the following cards should the second group of bees fly to? A．①④ B．②③ C．①② D．③④ 13．Which of the following is TRUE according to the passage? A．Our brains are 8,600 times bigger than those of bees. B．Bees like bitter water rather than sweet water. C．After training, bees can learn even numbers more quickly than people. D．After training, bees can know the difference between even numbers and odd numbers. 14．What can we learn from the last paragraph? A．Bees have a great ability to learn numbers. B．Bees like odd numbers better than even numbers. C．Scientists know how bees learn numbers. D．Scientists know why bees can tell different numbers. 15．In which part of a newspaper can we read this passage? A．Animal World. B．Sports Life. C．Festival Week. D．Beautiful Cities. （四） Doing housework is a key part of family life. It helps improve the relationship among family members. However, lots of Chinese parents are unaware (不知道的) of the importance of doing housework and they think it is a waste of time. In order to know how often middle school students do housework at home, we did a survey among 1,200 students from Grade 7 to Grade 9 in a middle school. The following bar chart shows the result of our survey. From the bar chart, we find that only a small number of students usually do housework. Nearly half of the students in Grade 9 never do housework. The result makes us worried. After all, doing housework is good for students. It can teach students many important skills, like planning, timing, solving problems and so on. Doing housework can also teach students what responsibility is. Everyone should do something for the family. What’s more, doing housework can help students relax themselves and keep a balance between study and life. Therefore, we suggest that parents should encourage their children to do housework. They must learn one or two life skills every year so that they can be better prepared for an independent (独立的) life in the future. 16．What is the main idea of the first paragraph? A．Doing housework is not necessary for family life. B．Doing housework is important but many Chinese parents don’t realize it. C．Chinese parents all think doing housework is a waste of time. D．Family relationship has nothing to do with doing housework. 17．What can we learn from the bar chart? A．Students in all grades actively take part in housework. B．Over half of the students in Grade 8 never do housework. C．Students in Grade 7 do housework more often than students in Grade 9. D．The result of Grade 9 students is the least worrying among all grades. 18．Which is NOT the good point of doing housework? A．Relaxing a busy mind. B．Saving more time for study. C．Practicing planning and timing skills. D．Learning to be independent from parents. 19．What does the underlined word “responsibility” probably mean in Paragraph 4? A．技能 B．能力 C．责任 D．方法 20．What’s the purpose of the passage? A．To show the result of a recent survey. B．To teach students how to do housework. C．To point out a worrying problem for teachers in school. D．To remind people of the importance of doing housework. （五） Do you sometimes find you want to eat chocolate or ice cream very much? Do you then make it but feel guilty about it later? The next time this happens to you, think back if you have had enough sleep over the last 3-5 days. Many adults and even teens have noticed that they crave “midnight snacks” when working or watching TV late. New research shows that lack of sleep could lead us to have an increased appetite (食欲) — especially for the unhealthy kind. Recently, researchers at the University of Chicago carried out a study that clearly shows that a lack of sleep actually changes our brain chemistry! Studies were done on two control groups over four days. Both groups had their food and sleep strictly controlled. All of them received three meals. The only difference was that one group was allowed to sleep for 7.5 hours while the other group slept for a little more than four hours. During the following visit, their sleep patterns were exchanged. After the last night of the session, the volunteers were offered as much food as they wanted to eat. Researchers noticed that in both sessions, people who slept less ate on average 300 calories more than those who had slept more. This was much more calories than what their bodies would need to make up for the three fewer hours of sleep. _________ The researchers then analyzed the chemicals in the blood of the people in the study. What they noticed was surprising. High levels of ghrelin (a chemical that makes us hungry) and lower levels of leptin (the chemical that tells the brain that it is satisfied) were found in the people with less sleep. Even more surprising was that this group had higher levels of endocannabinoids — the same chemical that is caused by drugs. The endocannabinoid system causes a craving for sugar and fatty foods and leads to overeating even when the body is not hungry. This study suggests that sleep changes help produce chemicals in the body that are similar to taking drugs! Furthermore, researchers noticed that food cravings continued for a long period of time, well after the lack of sleep. This increases the risk of over-eating for longer periods, leading to obesity (肥胖). Your body needs 7 — 8 hours of sleep each night. So, the next time you reach for a bag of chips or a slice of decadent cake, think of the amount of sleep you have had recently! 21．The underlined word “crave” in Paragraph 2 most probably means ________. A．hope B．want C．hate D．dislike 22．From the passage, we can learn that ________. A．people feel guilty about eating chocolate B．unhealthy food makes people sleep less and less C．a person’s sleep has nothing to do with his/her appetite D．a study about sleep and obesity was carried out at the University of Chicago 23．What was the key difference between the two control groups in the University of Chicago study? A．The duration of sleep allowed. B．The type of meals they received. C．The timing of their blood tests. D．The environment in which they slept. 24．What might be used to fill in the blank? A．How did they do the experiment? B．What is going on? C．How much should we sleep every day? D．Why should we sleep more? 25．This article is mainly about ________. A．researchers working on people’s sleep B．how people’s sleep influences their appetite C．how much people need to eat after sleeping less D．a research about chemicals in the blood of people （六） When Ollie and I were on our way home, we talked about the Mother’s Day tea party at my house. Our families would celebrate together. I’d made a card for my mom, but I still wanted to find a present to go with it. Ollie wanted to buy roses for his mom, but everything was so expensive at the flower store. Just then, our neighbor Mrs. Nishikawa greeted us. She looked tired and said her garden was in a mess. Suddenly we had a good idea. Ollie and I offered to help. In return, Mrs. Nishikawa would let us pick some nice flowers from her garden. After half an hour, Ollie and I finished. Mrs. Nishikawa was happy with our work. So, we picked and wrapped some flowers in nice paper and went home. Then, we hid the flowers in my bedroom closet (壁橱). “At the right time, we’ll shout ‘Surprise!’” Ollie said. It was time for the tea party. We had a great time enjoying tea and cakes. When my sister and brother sang a song they had made up, Ollie and I quietly went to get our surprise. “No!” I shouted when I got to the bedroom. Everyone rushed to see what was happening. Right there, we saw my cats, Charlie and Cow, playing with the flowers! “It looks like the cats are having a party!” my mom laughed. “We made them at Mrs. Nishikawa’s for Mother’s Day!” Ollie said. “What a lovely thought! Thank you!” Ollie’s mom said. “And I think I know why the cats are excited.” She picked up some tiny green leaves-catnip (猫薄荷)! Ollie’s mom and my mom both said laughing was the best gift.

C．Laughter matters more than material gifts. D．Perfectly-hidden surprises always turn out well. （七） A young couple named Xiexie and Caicai has proved (证明) it by visiting 18 Asian countries on a budget of 40,000 yuan. But when they broke the news on Sina Weibo last week, many people didn’t seem to believe them. “It couldn’t be true,” said a microblogger named Uncle Fox on Sina Weibo. “I just don’t buy it.” Well, the truth is that there are smart ways to see the world. Many householders worldwide will let you live in their homes for free while they are away. And it is completely one-way. That means you don’t have to offer your house in exchange. You need to help take care of their pets and plants. Working in return for accommodation (食宿) is a great way to learn about a country. You can get practical experience (实践经历), and save a lot of dollars on accommodation. Many hostels (旅社) around the world offer discounted (打折的) rooms or free meals to guests if they take part in volunteering programs. All you need to do is to check hostels online to see if they have a volunteer discount. Would you be willing to volunteer a half-day of your vacation in order to get 50 percent off the cost of your room? It seems interesting that we can see the world in these ways. Why not have a try? 31．What does the sentence “I just don’t buy it.” mean? A．I just can’t buy it. B．I just have no money. C．I just don’t believe it. D．I just don’t understand it. 32．What do you need to look after when you live in their homes for free while the householders are away? A．Their children. B．Their old parents.

B．You can check hostels online to see if they have a volunteer discount. C．You will pay nothing for your rooms when you work in return in the hostels. D．You must offer your house in exchange when you live in their homes for free. 35．What is the best title of the passage? A．Traveling doesn’t have to cost much. B．Traveling is a good way to relax. C．The good way to learn about a country. D．A young couple visited 18 Asian countries. （八） THE AMERICAN TRAIL is a very popular section in the Smithsonian’s National Zoo. Visitors love to see the active animals. However, they may not be aware of the hard work of the zookeepers. Every day, the keepers are busy preparing food, training animals, among many other duties. Let’s take a look at one of their typical workdays. 7 a.m. The first thing we do in the morning is check on all the animals in our charge. We take a head count and make sure everyone appears healthy. Our North American beavers (河狸) are active at night. We give them a quick hello and try not to disturb their rest. 8 a.m. Every day, we sort through more than 100 pounds of fish for our sea lions and seals (海豹). Together with our volunteers, we make sure that the fish is of the highest quality before we feed it to an animal. 8:30 a.m. Our sea lions are fed many times a day. Each feeding is an opportunity for us to carefully check every part of their bodies. 9:30 a.m. It's time to train our gray wolves. We would ask for an action. If the animal performs the required movement, he or she will be given a meatball. Of course, the animals can choose to walk away, and they won’t be punished for doing that. 10:15 a.m. Our daily sea lion and seal show begins! Our visitors are always surprised at the intelligence of these animals. Through our shows, they also learn how to help protect sea animals. 1:45 p.m. Our beavers wake up. We feed them and do a careful body check on each of them. 2:20 p.m. We train the other animals, including the river otters (河獭) and the ravens (渡鸦). Neither rain nor cold can keep us from our duties. We’re always there to care for the animals. 36．The author of this article is most likely ________. A．an American Trail keeper B．the manager of the American Trail C．a regular visitor to the American Trail D．a volunteer in the Zoo 37．According to the article, the American Trail keepers quickly greet their North American beavers ________ before they wake up.

A．8:30 a.m. B．9:30 a.m. C．1:45 p.m. D．2:20 p.m. 40．Which of the following statements is TRUE according to the article? A．A gray wolf will be punished if it walks away when it is trained. B．The zookeepers count the animals every afternoon. C．The sea lions’ bodies are checked every day. D．When it is very cold, the zookeepers don’t need to take care of the animals. （九） In the 1970s, a gorilla known as Koko became world-famous when researchers taught her to use human sign language to communicate with people. There were numerous attempts (尝试) in the mid-1900s to teach human language to non-humans, such as Koko. But what we should have been thinking about was their abilities to engage in complex communication on their own terms instead of trying to teach an animal to talk to us in human language. Today, researchers are trying to figure out how living things already share information using their particular methods. This new field of study is known as digital bioacoustics (数字生物声学) and it involves using tools to understand the production of sounds and their effects on living things. Researchers in this field are using sensors, which are devices that pick up and record information on physical or chemical conditions. Some are also using artificial intelligence (AI) technology, an approach that uses algorithms (算法). The same algorithms that we use in tools such as Google Translate to translate documents can also be used to find patterns in nonhuman communication. Jeremy of Tel Aviv University studied nearly two dozen Egyptian fruit bats (埃及果蝠) for two and a half months and recorded their vocalizations (叫声). His team adapted (改造) a voice-recognition program to study 15,000 of the sounds. The algorithm matched specific sounds with specific things the bats were doing. Using this program, the researchers were able to classify most of the bats’ sounds. Jeremy and other researchers have found that bats have a much more complex language than we previously understood. Bats argue over food; they distinguish (区分) between genders when they communicate with one another, and they have individual names, or “signature calls”. That’s a great example of how AI is able to find these patterns from information gathered by sensors and microphones. AI reveals (显示) things that we cannot hear with our human ears alone because most bat communication happens above our hearing range and because bats speak much faster than we do. We have to slow it down to listen to it. That’s why we cannot listen like a bat, but our computers can. And our computers can also speak back to the bat by producing specific patterns. Digital bioacoustics is like an amazing hearing aid. It lets us listen to animals with both our digitally enhanced ears and our imagination. This is slowly opening our minds not only to the wonderful sounds that nonhumans make, but to a fundamental set of questions about the so-called divide between humans and nonhumans as well as our connection to other species. It’s also opening up new ways to think about protecting living things and our relationship with the planet. It’s pretty meaningful. 41．Regarding researchers’ efforts to teach animal human language, the author feels ________. A．negative B．unconcerned C．uncertain D．supportive 42．Researchers in digital bioacoustics are trying to study ________. A．how animals are using tools to produce their sounds B．how animals use different tools to share information C．how animals are taught to talk in human sign language D．how animals communicate with one another using sounds 43．What can we learn about AI applied in digital bioacoustics? A．It pairs certain animals’ sounds with their behaviors. B．It slows down animals’ sounds within humans’ hearing range. C．It adapts voice-recognition programs to record animals’ sounds. D．It translates specific nonhuman sound patterns into human language. 44．What does the word “signature” in Paragraph 4 most probably mean? A．Ordinary and common. B．Unique and specific. C．Loud and clear. D．Food-related and gender-linked. 45．According to the passage, the author may agree that ________. A．animals can be grouped according to their sound patterns B．scientists need to keep studying how animals produce sounds C．digital bioacoustics may inspire humans to rethink their relationship with animals D．the focus of digital bioacoustics should be the divide between humans and nonhumans （十） AI is playing an important role in education nowadays. It brings a new teaching and learning method for teachers and students, and it makes education more personalized (个性化的) and efficient (有效的). For students, AI can provide personalized learning plans. Every student has different learning levels and habits. AI can collect students’ study data (数据) and find out their weak points. Then it makes a special learning plan for each student. For example, if a student is weak in math, AI will give him more exercises and video lessons. Students can learn at their own speed and improve their weak points quickly. AI also makes learning more interesting. Many AI learning apps have fun games and interactive (互动的) lessons. Students can learn English words by playing games, and learn science knowledge by doing interactive experiments. More and more students like using AI learning apps. This makes students love learning and study more actively. For teachers, AI can help them with their work. It can correct students’ homework quickly. This saves teachers a lot of time, and they can have more time to talk with students and help them solve more difficult problems. Besides, AI can design proper teaching plans for students based on their own situations. With AI’s help, teachers can satisfy students’ different learning needs. AI is a great helper in education, but it can’t replace teachers. Teachers’ love and care for students are the most important in education. AI can only help teachers teach better and students learn better. The combination (融合) of AI and teachers will make education better and better. 46．How does AI change education nowadays? A．It makes education more difficult and boring. B．It makes education more traditional and simple. C．It makes education more expensive and tiring. D．It makes education more personalized and efficient. 47．How does the writer support the main idea of paragraph 2? A．By telling a story. B．By asking questions. C．By giving an example. D．By showing numbers. 48．What can AI do for teachers according to the text? A．It can help teachers take a long holiday. B．It can help teachers correct students’ homework fast. C．It can take the place of teachers to give lessons. D．It can help teachers do housework at home. 49．What’s the structure of the passage? A． B． C． D． 50．What’s the best title for the passage? A．AI in science B．AI in daily life C．AI in Education D．The History of AI 试卷第1页（共3页） 试卷第1页（共3页） 学科网（北京）股份有限公司 $ 八年级英语期中真题汇编 阅读理解 CD 篇专项训练（解析） In the future, technology will bring great changes to farming, and “smart farming” will become the main direction.

D．Hard-working and honest. 10．What can we learn from the text? A．Hard work can bring good luck. B．Having a partner makes learning more fun. C．Even a small change can make a big difference. D．You’re never too young to achieve something big. 【答案】6．C 7．B 8．B 9．C 10．D 【导语】本文讲述了加拿大少年Lucien Distler在14岁时就拿到飞行执照完成单人飞行的故事，他受父亲的玩笑启发开始学习飞行，训练中进步很快，首次单飞时毫不紧张且享受过程，他认为凭借练习和自信可以实现任何目标。 【详解】6．第二段明确提到“With the licence, he could fly a small plane all by himself. His first solo flight happened on the day he turned 14. It is very unusual for someone that young to fly a plane alone.”，前后文的“all by himself”、“fly a plane alone”都对solo的含义作出解释，说明这次飞行是独自完成的，对应选项Single（独自的、单人的）。 7．第三段明确提到“During a family trip to an air show, he joked, ‘It would be funny if you became a pilot at 14.’ To his surprise, Lucien loved the idea a lot. Then they decided to start lessons together.”，说明是父亲在航展上开的一句玩笑激发了Lucien学开飞机的兴趣。 8．第五段明确提到“He said he was not scared or stressed at all. ‘The plane felt lighter without anyone beside me, and I enjoyed making radio calls,’ he said.”，说明Lucien第一次独自飞行时完全不害怕、不紧张，状态很放松，还很享受这次飞行，和选项B的描述完全吻合。 9．第四段明确提到“Lucien learnt quickly and passed two exams to get his licence. He even scored higher than his dad on the written test.”，能快速掌握飞行相关知识、笔试成绩比父亲还高，体现出他很聪明（Smart），经过长达一年的系统飞行训练、通过多门考核拿到飞行执照，也能看出他训练刻苦努力（Hard-working）。 10．全文讲述了14岁的Lucien在大多数同龄人还没拿到驾照的年纪，就通过努力拿到飞行执照、完成独自飞行的故事，第二段也明确提到“It is very unusual for someone that young to fly a plane alone”，印证了哪怕年纪很小，也可以完成了不起的成就，对应“永远不要因为年纪小就觉得没法实现重大目标”的内涵。 Can you say the meaning of “zero”? Can you do addition and subtraction (加减法)? Most people can. But do you know bees can do these things too? A study shows that bees have even greater maths abilities. After some training, they can know the difference between even numbers and odd numbers. Some Australian scientists put up different cards with an odd (奇数的) or even (偶数的) number of triangles (三角形). They used the numbers 1 to 10. Then they trained the first group of bees to choose odd numbers and the second group to choose even numbers. If a bee flew to the right card, it would get sweet water. If it chose the wrong card, it got bitter (苦的) water. In a short time, all the bees knew what odd numbers or even numbers were. They could fly to the right numbers 80% of the time. After that, the scientists added new cards with the numbers 11 and 12. The bees never saw the numbers in their training before, but they could choose rightly 70% of the time. Surprisingly, the bees even learned odd numbers more quickly than people. How did the bees learn the numbers so fast? Scientists didn’t have a clear idea. But they believe if they find the answer, it will help them build better and faster computers. After all, a bee’s brain is about 86,000 times smaller than ours! 11．How does the writer start the passage? A．By listing facts. B．By giving examples. C．By asking questions. D．By using pictures. 12．Which of the following cards should the second group of bees fly to? A．①④ B．②③ C．①② D．③④ 13．Which of the following is TRUE according to the passage? A．Our brains are 8,600 times bigger than those of bees. B．Bees like bitter water rather than sweet water. C．After training, bees can learn even numbers more quickly than people. D．After training, bees can know the difference between even numbers and odd numbers. 14．What can we learn from the last paragraph? A．Bees have a great ability to learn numbers. B．Bees like odd numbers better than even numbers. C．Scientists know how bees learn numbers. D．Scientists know why bees can tell different numbers. 15．In which part of a newspaper can we read this passage? A．Animal World. B．Sports Life. C．Festival Week. D．Beautiful Cities. 【答案】11．C 12．B 13．D 14．A 15．A 【导语】本文是一篇说明文，主要介绍一项科学研究：蜜蜂经过训练能够区分奇数和偶数，甚至学习奇数的速度比人类更快，科学家希望弄清背后原理，助力研发更先进的计算机。 【详解】11．根据文章第一段开头连续提出两个问句“Can you say the meaning of ‘zero’? Can you do addition and subtraction (加减法)?”，作者通过提问的方式开启整篇文章。 12．根据文章第二段中“the second group to choose even numbers”，第二组蜜蜂需要选择偶数（三角形数量为偶数）。①3个（奇数）②4个（偶数）③6个（偶数）④5个（奇数），所以选②③。 13．根据文章第一段中“After some training, they can know the difference between even numbers and odd numbers.”，说明经过训练，蜜蜂可以分清奇数和偶数。 14．根据文章最后一段讲述蜜蜂大脑体积极小，却具备快速识数的强大能力，科学家还不清楚蜜蜂快速学会数字的原理，但认为该研究有助于研发计算机。 15．文章介绍蜜蜂的科研实验，属于动物相关内容，对应报纸板块Animal World（动物世界）。 Doing housework is a key part of family life. It helps improve the relationship among family members. However, lots of Chinese parents are unaware (不知道的) of the importance of doing housework and they think it is a waste of time. In order to know how often middle school students do housework at home, we did a survey among 1,200 students from Grade 7 to Grade 9 in a middle school. The following bar chart shows the result of our survey. From the bar chart, we find that only a small number of students usually do housework. Nearly half of the students in Grade 9 never do housework. The result makes us worried. After all, doing housework is good for students. It can teach students many important skills, like planning, timing, solving problems and so on. Doing housework can also teach students what responsibility is. Everyone should do something for the family. What’s more, doing housework can help students relax themselves and keep a balance between study and life. Therefore, we suggest that parents should encourage their children to do housework. They must learn one or two life skills every year so that they can be better prepared for an independent (独立的) life in the future. 16．What is the main idea of the first paragraph? A．Doing housework is not necessary for family life. B．Doing housework is important but many Chinese parents don’t realize it. C．Chinese parents all think doing housework is a waste of time. D．Family relationship has nothing to do with doing housework. 17．What can we learn from the bar chart? A．Students in all grades actively take part in housework. B．Over half of the students in Grade 8 never do housework. C．Students in Grade 7 do housework more often than students in Grade 9. D．The result of Grade 9 students is the least worrying among all grades. 18．Which is NOT the good point of doing housework? A．Relaxing a busy mind. B．Saving more time for study. C．Practicing planning and timing skills. D．Learning to be independent from parents. 19．What does the underlined word “responsibility” probably mean in Paragraph 4? A．技能 B．能力 C．责任 D．方法 20．What’s the purpose of the passage? A．To show the result of a recent survey. B．To teach students how to do housework. C．To point out a worrying problem for teachers in school. D．To remind people of the importance of doing housework. 【答案】16．B 17．C 18．B 19．C 20．D 【导语】本文是一篇说明文，文章通过调查数据和分析，阐述了做家务对家庭关系和学生成长的重要性，并呼吁家长鼓励孩子参与家务劳动。 【详解】16．根据“Doing housework is a key part of family life… However, lots of Chinese parents are unaware of the importance of doing housework”本段主要强调做家务很重要，但许多父母未意识到这一点。 17．根据条形图可知，七年级经常做家务的人数是126人，九年级经常做家务的人数是116人，所以七年级的学生比九年级的学生更经常做家务。 18．根据“It can teach students many important skills, like planning, timing, solving problems and so on.”和“What’s more, doing housework can help students relax themselves and keep a balance between study and life.”以及“They must learn one or two life skills every year so that they can be better prepared for an independent life in the future.”可知，做家务可以教会学生许多重要的技能，比如计划、定时、解决问题等等。更重要的是，做家务可以帮助学生放松自己，保持学习和生活之间的平衡。他们每年必须学习一两项生活技能，以便为将来的独立生活做更好的准备。没有提到节省了更多的学习时间。 19．根据“Everyone should do something for the family.”可知，每个人都应该为家庭做点什么，即做家务还可以教会学生什么是责任，所以“responsibility”是“责任”的意思。 20．通读全文并根据“we suggest that parents should encourage their children to do housework”可知，文章目的是提醒人们做家务的重要性。 Do you sometimes find you want to eat chocolate or ice cream very much? Do you then make it but feel guilty about it later? The next time this happens to you, think back if you have had enough sleep over the last 3-5 days. Many adults and even teens have noticed that they crave “midnight snacks” when working or watching TV late. New research shows that lack of sleep could lead us to have an increased appetite (食欲) — especially for the unhealthy kind. Recently, researchers at the University of Chicago carried out a study that clearly shows that a lack of sleep actually changes our brain chemistry! Studies were done on two control groups over four days. Both groups had their food and sleep strictly controlled. All of them received three meals. The only difference was that one group was allowed to sleep for 7.5 hours while the other group slept for a little more than four hours. During the following visit, their sleep patterns were exchanged. After the last night of the session, the volunteers were offered as much food as they wanted to eat. Researchers noticed that in both sessions, people who slept less ate on average 300 calories more than those who had slept more. This was much more calories than what their bodies would need to make up for the three fewer hours of sleep. _________ The researchers then analyzed the chemicals in the blood of the people in the study. What they noticed was surprising. High levels of ghrelin (a chemical that makes us hungry) and lower levels of leptin (the chemical that tells the brain that it is satisfied) were found in the people with less sleep. Even more surprising was that this group had higher levels of endocannabinoids — the same chemical that is caused by drugs. The endocannabinoid system causes a craving for sugar and fatty foods and leads to overeating even when the body is not hungry. This study suggests that sleep changes help produce chemicals in the body that are similar to taking drugs! Furthermore, researchers noticed that food cravings continued for a long period of time, well after the lack of sleep. This increases the risk of over-eating for longer periods, leading to obesity (肥胖). Your body needs 7 — 8 hours of sleep each night. So, the next time you reach for a bag of chips or a slice of decadent cake, think of the amount of sleep you have had recently! 21．The underlined word “crave” in Paragraph 2 most probably means ________. A．hope B．want C．hate D．dislike 22．From the passage, we can learn that ________. A．people feel guilty about eating chocolate B．unhealthy food makes people sleep less and less C．a person’s sleep has nothing to do with his/her appetite D．a study about sleep and obesity was carried out at the University of Chicago 23．What was the key difference between the two control groups in the University of Chicago study? A．The duration of sleep allowed. B．The type of meals they received. C．The timing of their blood tests. D．The environment in which they slept. 24．What might be used to fill in the blank? A．How did they do the experiment? B．What is going on? C．How much should we sleep every day? D．Why should we sleep more? 25．This article is mainly about ________. A．researchers working on people’s sleep B．how people’s sleep influences their appetite C．how much people need to eat after sleeping less D．a research about chemicals in the blood of people 【答案】21．B 22．D 23．A 24．B 25．B 【导语】本文介绍芝加哥大学的研究表明，睡眠不足会改变人体血液中的相关化学物质水平，提升食欲，让人更渴望摄入不健康的高糖高脂食物，长期睡眠不足还会提升肥胖风险，说明睡眠会对人的食欲产生显著影响。 【详解】21．第二段中提到：“Many adults and even teens have noticed that they crave ‘midnight snacks’ when working or watching TV late.”，结合上下文，前文提到人们有时会非常想吃巧克力或冰淇淋，后文提到熬夜工作或看电视时的“午夜零食”，可推知crave表达的是强烈的想要、渴望的含义，对应选项B“want”。 22．第四段明确提到：“Recently, researchers at the University of Chicago carried out a study...”，且文章后半部分讨论了由此导致的肥胖风险，选项D正确。A项只是引子，不是研究结论；B项因果倒置，是睡眠少导致想吃不健康食物；C项与全文主旨相反。 23．第四段明确指出：“The only difference was that one group was allowed to sleep for 7.5 hours while the other group slept for a little more than four hours.”，说明两组之间唯一的区别是允许的睡眠时长（duration of sleep）。 24．空格前的段落介绍了实验的分组设置和观察到的“睡眠更少的人摄入热量更多”的现象，空格后开始分析血液中的化学物质、解释该现象背后的原理，因此空格处的过渡句应当是引出对背后原因的探究，“发生了什么（背后的原理是什么）”符合上下文逻辑。A选项实验过程前文已经介绍过，C选项每日睡眠时长、D选项为什么要多睡觉均无法衔接前后内容。故选B。 25．全文围绕核心主题“睡眠不足会改变人体化学物质，进而影响人的食欲，让人更渴望摄入不健康食物”展开，A选项仅提及研究者研究睡眠，偏离核心；C选项仅涉及睡眠不足后的进食量，是细节内容；D选项仅提及血液化学物质的研究，是研究的部分内容，均不能概括全文。只有B选项“人的睡眠如何影响食欲”贴合全文主旨。 When Ollie and I were on our way home, we talked about the Mother’s Day tea party at my house. Our families would celebrate together. I’d made a card for my mom, but I still wanted to find a present to go with it. Ollie wanted to buy roses for his mom, but everything was so expensive at the flower store. Just then, our neighbor Mrs. Nishikawa greeted us. She looked tired and said her garden was in a mess. Suddenly we had a good idea. Ollie and I offered to help. In return, Mrs. Nishikawa would let us pick some nice flowers from her garden. After half an hour, Ollie and I finished. Mrs. Nishikawa was happy with our work. So, we picked and wrapped some flowers in nice paper and went home. Then, we hid the flowers in my bedroom closet (壁橱). “At the right time, we’ll shout ‘Surprise!’” Ollie said. It was time for the tea party. We had a great time enjoying tea and cakes. When my sister and brother sang a song they had made up, Ollie and I quietly went to get our surprise. “No!” I shouted when I got to the bedroom. Everyone rushed to see what was happening. Right there, we saw my cats, Charlie and Cow, playing with the flowers! “It looks like the cats are having a party!” my mom laughed. “We made them at Mrs. Nishikawa’s for Mother’s Day!” Ollie said. “What a lovely thought! Thank you!” Ollie’s mom said. “And I think I know why the cats are excited.” She picked up some tiny green leaves-catnip (猫薄荷)! Ollie’s mom and my mom both said laughing was the best gift. We all laughed together, making it a Mother’s Day to remember! 26．Why did the writer and Ollie want to find presents for their moms? A．Because it was Mother’s Day. B．Because they wanted to show off. C．Because their moms liked presents. D．Because their moms would have a birthday party. 27．What does the underlined word “wrapped” in Paragraph 2 mean in Chinese? A．包装 B．带走 C．采摘 D．赠送 28．How did the writer and Ollie get the presents? A．They made the presents themselves. B．They put their money together to buy the presents. C．They cleaned their neighbors’ houses for the presents. D．They helped Mrs. Nishikawa in return for the presents. 29．How might the writer feel when he reached the closet to get the surprise? A．Happy. B．Nervous. C．Shocked. D．Interested. 30．What lesson can we learn from the writer’s experience? A．Planning is necessary for everything. B．Presents are important for showing love. C．Laughter matters more than material gifts. D．Perfectly-hidden surprises always turn out well. 【答案】26．A 27．A 28．D 29．C 30．C 【导语】本文是一篇记叙文，主要讲述了作者和Ollie在母亲节为妈妈们准备惊喜礼物的故事。 【详解】26．根据文章第1段“Our families would celebrate together. I’d made a card for my mom, but I still wanted to find a present to go with it.”（我们的家人要一起庆祝。我给妈妈做了一张卡片，但我还想找份礼物搭配它。）可知，他们准备礼物是因为母亲节的庆祝活动。 27．根据文章第2段“we picked and wrapped some flowers in nice paper”（我们采摘了一些花并用漂亮的纸包起来）的上下文，“wrapped”与“in nice paper”搭配，最合理的解释是“包装”。 28．根据文章第2段“Ollie and I offered to help. In return, Mrs. Nishikawa would let us pick some nice flowers from her garden.”（Ollie和我主动提供帮助。作为回报，西川太太让我们从她的花园里摘一些漂亮的花。）可知，他们是通过帮助邻居换取礼物。 29．根据文章第5段“‘No!’ I shouted when I got to the bedroom.”（“不！”我到达卧室时喊道。）以及下文描述发现猫在玩花的场景，可以推断作者当时感到震惊。 30．根据文章最后一段“Ollie’s mom and my mom both said laughing was the best gift. We all laughed together, making it a Mother’s Day to remember!”（Ollie的妈妈和我的妈妈都说笑声是最好的礼物。我们一起欢笑，让这个母亲节值得铭记！）可知，欢笑比物质礼物更重要。 A young couple named Xiexie and Caicai has proved (证明) it by visiting 18 Asian countries on a budget of 40,000 yuan. But when they broke the news on Sina Weibo last week, many people didn’t seem to believe them. “It couldn’t be true,” said a microblogger named Uncle Fox on Sina Weibo. “I just don’t buy it.” Well, the truth is that there are smart ways to see the world. Many householders worldwide will let you live in their homes for free while they are away. And it is completely one-way. That means you don’t have to offer your house in exchange. You need to help take care of their pets and plants. Working in return for accommodation (食宿) is a great way to learn about a country. You can get practical experience (实践经历), and save a lot of dollars on accommodation. Many hostels (旅社) around the world offer discounted (打折的) rooms or free meals to guests if they take part in volunteering programs. All you need to do is to check hostels online to see if they have a volunteer discount. Would you be willing to volunteer a half-day of your vacation in order to get 50 percent off the cost of your room? It seems interesting that we can see the world in these ways. Why not have a try? 31．What does the sentence “I just don’t buy it.” mean? A．I just can’t buy it. B．I just have no money. C．I just don’t believe it. D．I just don’t understand it. 32．What do you need to look after when you live in their homes for free while the householders are away? A．Their children. B．Their old parents. C．Their kitchen and rooms. D．Their pets and plants. 33．How many smart ways to see the world does the passage show us? A．Two. B．Three. C．Four. D．Five. 34．Which of the following is TRUE according to the passage? A．Lots of people believe that couple called Xiexie and Caicai. B．You can check hostels online to see if they have a volunteer discount. C．You will pay nothing for your rooms when you work in return in the hostels. D．You must offer your house in exchange when you live in their homes for free. 35．What is the best title of the passage? A．Traveling doesn’t have to cost much. B．Traveling is a good way to relax. C．The good way to learn about a country. D．A young couple visited 18 Asian countries. 【答案】31．C 32．D 33．B 34．B 35．A 【导语】本文是一篇说明文，主要通过一对夫妇低价游亚洲的故事引出话题，核心介绍了三种低成本看世界的方式（免费寄宿、以工换宿、旅社志愿者），探讨如何聪明地省钱旅行。 【详解】31．根据文章第一段中“many people didn’t seem to believe them.”及“It couldn’t be true”可推知说话者表示不相信。 32．根据文章第二段中“You need to help take care of their pets and plants.”可推知需要照顾宠物和植物。 33．根据文章第二段中“Many house holders...”, 第三段中“Working in return...”及第四段中“Many hostels...”可知，分别介绍了一种方式，共三种。 34．根据文章第四段中“All you need to do is to check hostels online to see if they have a volunteer discount.”可知，你可以上网查询旅社是否有志愿者折扣，B选项表述与原文一致。 35．全文围绕“smart ways to see the world”即低成本旅行方式展开，说明旅行不必花费很多钱。 THE AMERICAN TRAIL is a very popular section in the Smithsonian’s National Zoo. Visitors love to see the active animals. However, they may not be aware of the hard work of the zookeepers. Every day, the keepers are busy preparing food, training animals, among many other duties. Let’s take a look at one of their typical workdays. 7 a.m. The first thing we do in the morning is check on all the animals in our charge. We take a head count and make sure everyone appears healthy. Our North American beavers (河狸) are active at night. We give them a quick hello and try not to disturb their rest. 8 a.m. Every day, we sort through more than 100 pounds of fish for our sea lions and seals (海豹). Together with our volunteers, we make sure that the fish is of the highest quality before we feed it to an animal. 8:30 a.m. Our sea lions are fed many times a day. Each feeding is an opportunity for us to carefully check every part of their bodies. 9:30 a.m. It's time to train our gray wolves. We would ask for an action. If the animal performs the required movement, he or she will be given a meatball. Of course, the animals can choose to walk away, and they won’t be punished for doing that. 10:15 a.m. Our daily sea lion and seal show begins! Our visitors are always surprised at the intelligence of these animals. Through our shows, they also learn how to help protect sea animals. 1:45 p.m. Our beavers wake up. We feed them and do a careful body check on each of them. 2:20 p.m. We train the other animals, including the river otters (河獭) and the ravens (渡鸦). Neither rain nor cold can keep us from our duties. We’re always there to care for the animals. 36．The author of this article is most likely ________. A．an American Trail keeper B．the manager of the American Trail C．a regular visitor to the American Trail D．a volunteer in the Zoo 37．According to the article, the American Trail keepers quickly greet their North American beavers ________ before they wake up. A．about 4 hours B．about 7 hours C．about 10 hours D．about 12 hours 38．According to the article, at a sea lion and seal show, visitors will ________. ①be given chances to feed the animals       ②learn how to help protect sea animals ③realize how intelligent these animals are  ④understand the hard work of the zookeepers A．①② B．②③ C．③④ D．①④ 39．When do zookeepers give beavers food every day? A．8:30 a.m. B．9:30 a.m. C．1:45 p.m. D．2:20 p.m. 40．Which of the following statements is TRUE according to the article? A．A gray wolf will be punished if it walks away when it is trained. B．The zookeepers count the animals every afternoon. C．The sea lions’ bodies are checked every day. D．When it is very cold, the zookeepers don’t need to take care of the animals. 【答案】36．A 37．B 38．B 39．C 40．C 【导语】本文是一篇说明文，主要以时间轴的形式记录了史密森尼国家动物园“美国小径”展区饲养员的典型工作日，介绍了他们从早到晚照顾动物、训练动物及开展科普展示的具体工作内容。 【详解】36．根据文章第一段中“Let’s take a look at one of their typical workdays.”以及后文多次使用第一人称复数“we”来描述具体工作，如“The first thing we do in the morning is check on all the animals in our charge.”，可推断作者身份是饲养员团队的一员。 37．根据“7 a.m.”部分中“We give them a quick hello and try not to disturb their rest.”以及“1:45 p.m.”部分中“Our beavers wake up.”，从早上7点到下午1点45分，时间间隔约为6小时45分钟，最接近7小时。 38．根据“10:15 a.m.”部分中“Our visitors are always surprised at the intelligence of these animals. Through our shows, they also learn how to help protect sea animals.”，可知游客在表演中会意识到动物的智力并学习如何保护海洋动物，对应内容②和③。 39．根据“1:45 p.m.”部分中“Our beavers wake up. We feed them and do a careful body check on each of them.”，可知饲养员每天在下午1:45给河狸喂食。 40．根据“8:30 a.m.”部分中“Our sea lions are fed many times a day. Each feeding is an opportunity for us to carefully check every part of their bodies.”，结合全文提到的每日工作流程，可知海狮的身体每天都会接受检查。 In the 1970s, a gorilla known as Koko became world-famous when researchers taught her to use human sign language to communicate with people. There were numerous attempts (尝试) in the mid-1900s to teach human language to non-humans, such as Koko. But what we should have been thinking about was their abilities to engage in complex communication on their own terms instead of trying to teach an animal to talk to us in human language. Today, researchers are trying to figure out how living things already share information using their particular methods. This new field of study is known as digital bioacoustics (数字生物声学) and it involves using tools to understand the production of sounds and their effects on living things. Researchers in this field are using sensors, which are devices that pick up and record information on physical or chemical conditions. Some are also using artificial intelligence (AI) technology, an approach that uses algorithms (算法). The same algorithms that we use in tools such as Google Translate to translate documents can also be used to find patterns in nonhuman communication. Jeremy of Tel Aviv University studied nearly two dozen Egyptian fruit bats (埃及果蝠) for two and a half months and recorded their vocalizations (叫声). His team adapted (改造) a voice-recognition program to study 15,000 of the sounds. The algorithm matched specific sounds with specific things the bats were doing. Using this program, the researchers were able to classify most of the bats’ sounds. Jeremy and other researchers have found that bats have a much more complex language than we previously understood. Bats argue over food; they distinguish (区分) between genders when they communicate with one another, and they have individual names, or “signature calls”. That’s a great example of how AI is able to find these patterns from information gathered by sensors and microphones. AI reveals (显示) things that we cannot hear with our human ears alone because most bat communication happens above our hearing range and because bats speak much faster than we do. We have to slow it down to listen to it. That’s why we cannot listen like a bat, but our computers can. And our computers can also speak back to the bat by producing specific patterns. Digital bioacoustics is like an amazing hearing aid. It lets us listen to animals with both our digitally enhanced ears and our imagination. This is slowly opening our minds not only to the wonderful sounds that nonhumans make, but to a fundamental set of questions about the so-called divide between humans and nonhumans as well as our connection to other species. It’s also opening up new ways to think about protecting living things and our relationship with the planet. It’s pretty meaningful. 41．Regarding researchers’ efforts to teach animal human language, the author feels ________. A．negative B．unconcerned C．uncertain D．supportive 42．Researchers in digital bioacoustics are trying to study ________. A．how animals are using tools to produce their sounds B．how animals use different tools to share information C．how animals are taught to talk in human sign language D．how animals communicate with one another using sounds 43．What can we learn about AI applied in digital bioacoustics? A．It pairs certain animals’ sounds with their behaviors. B．It slows down animals’ sounds within humans’ hearing range. C．It adapts voice-recognition programs to record animals’ sounds. D．It translates specific nonhuman sound patterns into human language. 44．What does the word “signature” in Paragraph 4 most probably mean? A．Ordinary and common. B．Unique and specific. C．Loud and clear. D．Food-related and gender-linked. 45．According to the passage, the author may agree that ________. A．animals can be grouped according to their sound patterns B．scientists need to keep studying how animals produce sounds C．digital bioacoustics may inspire humans to rethink their relationship with animals D．the focus of digital bioacoustics should be the divide between humans and nonhumans 【答案】41．A 42．D 43．A 44．B 45．C 【导语】本文是一篇说明文，介绍了数字生物声学这一新兴领域，讲述了研究人员如何利用传感器和人工智能技术解读动物声音及其行为模式，旨在探讨该技术如何帮助人类重新思考与非人类物种的关系及保护方式。 【详解】41．第一段提到：“But what we should have been thinking about was...in human language.”，作者认为过去教动物人类语言的做法不是重点，而应关注动物自身的交流能力，由此推断作者对此持否定态度。 42．第二段介绍：“Today, researchers are trying to figure out how living things already share information using their particular methods.”，数字生物声学领域的研究者致力于了解生物如何用各自的方法分享信息，即动物如何利用声音相互交流。 43．第四段指出：“The algorithm matched specific sounds with specific things the bats were doing.”，应用在数字生物声学中的人工智能算法能够将动物的特定声音与其特定行为进行匹配。 44．第四段介绍：“Bats argue over food; they distinguish (区分)between genders when they communicate with one another, and they have individual names, or ‘signature calls’.”，蝙蝠在相互交流时会区分性别，并且拥有各自的名称；由此推断“signature calls”指个体独有的叫声，“signature”意为“独特且具体的”。 45．最后一段介绍：“This is slowly opening our minds...our connection to other species.”，作者认为数字生物声学能启发人类重新思考与动物之间的关系。 AI is playing an important role in education nowadays. It brings a new teaching and learning method for teachers and students, and it makes education more personalized (个性化的) and efficient (有效的). For students, AI can provide personalized learning plans. Every student has different learning levels and habits. AI can collect students’ study data (数据) and find out their weak points. Then it makes a special learning plan for each student. For example, if a student is weak in math, AI will give him more exercises and video lessons. Students can learn at their own speed and improve their weak points quickly. AI also makes learning more interesting. Many AI learning apps have fun games and interactive (互动的) lessons. Students can learn English words by playing games, and learn science knowledge by doing interactive experiments. More and more students like using AI learning apps. This makes students love learning and study more actively. For teachers, AI can help them with their work. It can correct students’ homework quickly. This saves teachers a lot of time, and they can have more time to talk with students and help them solve more difficult problems. Besides, AI can design proper teaching plans for students based on their own situations. With AI’s help, teachers can satisfy students’ different learning needs. AI is a great helper in education, but it can’t replace teachers. Teachers’ love and care for students are the most important in education. AI can only help teachers teach better and students learn better. The combination (融合) of AI and teachers will make education better and better. 46．How does AI change education nowadays? A．It makes education more difficult and boring. B．It makes education more traditional and simple. C．It makes education more expensive and tiring. D．It makes education more personalized and efficient. 47．How does the writer support the main idea of paragraph 2? A．By telling a story. B．By asking questions. C．By giving an example. D．By showing numbers. 48．What can AI do for teachers according to the text? A．It can help teachers take a long holiday. B．It can help teachers correct students’ homework fast. C．It can take the place of teachers to give lessons. D．It can help teachers do housework at home. 49．What’s the structure of the passage? A． B． C． D． 50．What’s the best title for the passage? A．AI in science B．AI in daily life C．AI in Education D．The History of AI 【答案】46．D 47．C 48．B 49．A 50．C 【导语】本文介绍了人工智能在教育领域的重要作用，它能为学生提供个性化学习方案、提升学习趣味性，也能辅助教师减轻工作负担，同时指出人工智能无法取代教师，二者融合会推动教育不断发展。 【详解】46．根据原文第一段“it makes education more personalized (个性化的) and efficient (有效的)”，直接对应选项D的表述“它使教育更加个性化和高效”。 47．第二段核心观点是人工智能可以为学生提供个性化学习计划，段落中通过“ For example, if a student is weak in math, AI will give him more exercises and video lessons”的具体例子来支撑观点，属于举例子的论证方式。 48．根据原文第四段“It can correct students’ homework quickly”，可知人工智能可以帮助教师快速批改学生作业。 49．本文第一段总述人工智能在教育中发挥重要作用；第二、三、四段分别从助力学生个性化学习、提升学习趣味性、辅助教师工作三个并列维度展开分述；最后一段总结说明人工智能是教育的好帮手但无法取代教师，二者融合会让教育更好，属于总——分——总结构，对应选项A的图示。 50．全文围绕人工智能在教育领域的应用与作用展开论述，核心主题为教育中的人工智能。 试卷第1页（共3页） 试卷第1页（共3页） 学科网（北京）股份有限公司 $
