He always kept tidy and carried a positive attitude toward life, which even made his little naughty acts lovely. 　　He liked talking nonstop in class. I often reminded him that chatting without permission was not allowed. However, what impressed me most was his sincere response every time I corrected his bad behaviour: “Thank you for reminding me, teacher.” At first, I felt confused about his reaction, but gradually I got used to hearing these words many times every day. 　　One Friday, after learning a new knowledge point for a whole week, I found my students felt discouraged and easily annoyed with each other. Therefore, I asked everyone to write down classmates’ names and one warm comment for each classmate. All students handed in their sheets before leaving the classroom. 　　On Saturday, I copied each student’s name on separate paper and collected all the positive comments about them. On Monday, I passed these notes to every student. Some students’ lists covered two full pages. Soon, smiles appeared on everyone’s faces. “I never knew so many classmates like me!” Leo said, “Thank you for arranging this, teacher.” 　　No one talked about these notes in class later. I never learned whether they discussed the words with friends or family members. 　　Years later, I received a phone call from Leo’s parents, informing me of his passing away. I was greatly shocked. Soon a wallet was delivered to me. Inside were worn pieces of notebook paper, repeatedly folded and pasted. I recognized them at once — the list full of kind words his classmates had written for him. At that moment, tears filled my eyes. 24. What can we infer about Leo from the first two paragraphs? A. He liked talking a lot. B. He was unpopular among classmates. C. He ignored the teacher’s suggestions. D. He paid little attention to his appearance. 25. Why did the author ask students to write positive comments for each other? A. To express congratulations. B. To show personal preference. C. To achieve mutual understanding. D. To learn to appreciate others. 26. Which word group can best describe Leo? A. Naughty but creative. B. Gentle but impatient. C. Thankful and respectful. D. Serious and curious. 27. What message does the story convey? A. Classmates’ opinions have little influence on people. B. A teacher’s thoughtful method can positively influence students. C. Academic grades matter most for teenagers. D. Punishment works well to correct students’ mistakes. C 　　As autumn replaces summer, many people long for warm sunshine. When daylight becomes shorter, some people feel low-spirited. This common feeling is known as autumn blues. 　　Autumn blues is just a common seasonal mood change caused by reduced sunlight. However, for some people, this bad mood develops into a serious condition called Seasonal Affective Disorder (SAD). 　　SAD is a type of depression. Its symptoms usually begin in late autumn or early winter and disappear when spring and summer come. People suffering from SAD tend to sleep longer, eat more food, and lose interest in hobbies they once loved. Most patients feel upset, helpless and even hopeless. 　　Experts have not found the exact cause of SAD, but several factors are related to the illness. Researchers from Johns Hopkins University point out that less natural light in autumn and winter may disturb the human body’s biological clock and affect hormone production, such as melatonin and serotonin. These hormones control sleep quality and emotions. Such disorder may lead to depression. 　　There are ways to deal with SAD. Light treatment is widely used and effective. Doctors advise patients to get exposed to natural sunlight or special lighting equipment that copies sunlight. Light therapy helps balance hormones and return to regular daily life. 　　Besides light treatment, healthy lifestyles matter a lot. Keeping regular sleeping hours, taking exercise frequently and keeping balanced diets can ease SAD symptoms. Meanwhile, patients should turn to professional doctors to work out proper treatment plans. 　　According to research from the US National Institute of Mental Health, SAD mostly appears among young adults. Therefore, when you bury yourself in study, remember to walk outdoors to enjoy sunshine and gain energy from nature. 28. What information about SAD is true? A. It generally begins in early autumn. B. It will turn into permanent depression. C. Feeling sad is one of its main symptoms. D. It mainly troubles elderly people. 29. According to Johns Hopkins University, what may cause SAD? A. Unbalanced eating habits. B. Shortage of natural sunlight. C. Irregular sleeping time. D. Lack of physical exercise. 30. What does the underlined word “Handling” in Paragraph 5 mean? A. Searching for. B. Getting rid of. C. Covering up. D. Dealing with. 31. What can we infer from the last paragraph? A. Only young adults suffer from SAD. B. Sunshine outdoors alone can cure SAD completely. C. Outdoor activities and sunlight may help prevent SAD. D. It is never too late to enjoy the beauty of nature. D 　　Gir National Park in western India is the unique natural habitat of Asiatic lions. At the beginning of the 1900s, habitat loss and illegal hunting greatly reduced their population, with fewer than 50 individuals surviving. Over recent decades, protection efforts have achieved results. The number rose to about 670 in 2020. Even so, Asiatic lions are still listed as endangered species. 　　Tracking these lions is one of the biggest difficulties in protecting them. Some wild animals such as tigers and zebras have unique stripe patterns, which help researchers tell individuals apart. But Asiatic lions do not have such clear marks, so researchers need new methods. 　　In 2019, Banerjee, a researcher from India’s National Tiger Conservation Authority, created an AI system that can identify Asiatic lions accurately. This AI tool named SIMBA has been put into practical use. Banerjee says: “It will become a valuable tool for long-term lion observation. It helps forest workers calculate the lion population more precisely. In several years, we can collect plenty of data: the number of male and female lions, birth numbers and death numbers.” 　　However, Banerjee also expresses his concerns. He suggests making strict rules to prevent sensitive wildlife data from being stolen. “The biggest value of SIMBA is helping researchers design monitoring plans, which are key to protecting endangered wildlife. Without proper rules, all protective work may end up useless.” 32. What is the main difficulty in protecting Asiatic lions? A. Tracking the lions. B. Preventing illegal hunting. C. Protecting their living environment. D. Increasing their population size. 33. How does SIMBA offer help to researchers? A. By finding lions’ shelters. B. By tracking other wildlife. C. By watching wildlife poachers. D. By supplying accurate data. 34. What is Banerjee’s attitude towards the AI system? A. It should be popularized worldwide. B. It has already saved endangered animals. C. People should realize its potential risks. D. We should ignore its shortcomings. 35. Which title suits the text best? A. The Biggest Challenge Facing Asiatic Lions B. Ways to Protect Asiatic Lions C. AI Technology Used in Wildlife Protection D. An AI Tool for Protecting Endangered Asiatic Lions 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。选项中有两项为多余选项。 　　Most sports have winners and losers, but winning every match is not the purpose of sports. Real goals include taking exercise, enjoying yourself and learning social qualities such as sportsmanship. 　　Good sportsmanship is built on respect. Good athletes respect teammates, opponents, coaches, referees and other staff in competitions. 36　　　　　　　　　　　　　　　　 They shout at teammates and argue with coaches or referees. 　　Children usually learn sportsmanship, good or bad, from adults around them. 37　　　　　　　　　　　　　　　　 If parents and coaches show disrespect to audiences and referees, children will copy such behaviour on the sports field. 　　38　　　　　　　　　　　　　　　　 Some are simple actions, like shaking hands with competitors before games. Others require more courage, for example, praising wonderful moves made by the opposing team. 　　Learning good sportsmanship matters greatly. It helps you develop politeness and respect, which can influence all parts of your life. 39　　　　　　　　　　　　　　　　 Good behaviour at school will gradually turn into good manners in your future work. 　　Try to be a sportsman with good qualities in everything you do! 40　　　　　　　　　　　　　　　　 When others see you understand that winning is not everything, they will focus on more important things: fun, exercise and self-improvement. A. Good sportsmanship can be shown in different ways. B. Bad sportsmanship, on the contrary, means disrespect. C. Your behaviour can set a powerful example for other people. D. Parents and coaches set examples that children tend to follow. E. We can be good competitors by encouraging others instead of laughing at them. F. Forming good sportsmanship early helps you keep it as you grow older. G. If you behave well on the sports field, you will probably do the same at school. 第三部分 语言运用（共两节，满分30分） 第一节（共15小题；每小题1分，满分15分） 　　阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳选项。 　　When I was younger, I did well in mathematics.

Maybe I just needed to 51　　　　 it. 　　52　　　　 is much like algebra. There are many things we cannot fully 53　　　　. The truth is: the more love we give away, the more love we own. The more we share kindness, the more it 54　　　　 inside us. The more we help others, the more we benefit ourselves. It is hard to explain, but it feels right. Just accept this 55　　　　! 41.

One weekend evening, she had a sharp quarrel with her mother over trivial daily matters. Feeling wronged and furious, she rushed out of home without taking any money or phone. Tears blurred her eyes as she walked aimlessly along the quiet street. She had always thought her mother was strict and never truly understood her feelings. After wandering for a long time, hunger overwhelmed her. She stopped in front of a roadside snack stall, staring at the steaming hot dumplings. With no money in hand, she could only sigh helplessly and prepare to leave. 　　The kind stall owner noticed her lonely and upset look and called out gently, “Hi kid, are you hungry? Want a bowl of dumplings?” 　　Sophie lowered her head and replied shyly, “I really want to eat, but I don’t have any money with me.” 　　“It’s fine, it’s on me. Come and sit down,” the owner smiled warmly. 　　Soon a bowl of hot dumplings was served. The warm food comforted her empty stomach, and tears streamed down her face again. 　　Seeing this, the owner asked softly, “Why are you crying, honey?” 　　“I’m just so touched,” Sophie sobbed. “A stranger is willing to treat me to dinner, but my mom always blames me and never gives in to me. She is so unkind to me.” 　　The owner shook his head and smiled patiently. “Think carefully. I only give you a bowl of dumplings, and you are so grateful. But your mother has accompanied you, taken care of you and devoted everything to you since you were born. How many selfless things has she done for you?” 　　Sophie froze on the spot, lost in deep thought. She suddenly recalled her mother’s countless warm moments: getting up early to prepare breakfast, staying up late to accompany her study, tolerating all her bad tempers. She felt extremely ashamed. She was grateful for a stranger’s tiny kindness, but ignored her mother’s long-term selfless love. 　　On the way home, Sophie made up her mind to sincerely apologize to her mother and cherish her family’s love. 注意： 1. 续写词数150左右； 2. 按照格式在答题卡作答。 Para 1: As Sophie approached her house, she slowed down and took a deep, steady breath.

I cherished all 34 children, yet Leo was really special. He always kept tidy and carried a positive attitude toward life, which even made his little naughty acts lovely. 　　He liked talking nonstop in class.

However, what impressed me most was his sincere response every time I corrected his bad behaviour: “Thank you for reminding me, teacher.” At first, I felt confused about his reaction, but gradually I got used to hearing these words many times every day. 　　One Friday, after learning a new knowledge point for a whole week, I found my students felt discouraged and easily annoyed with each other.

Good athletes respect teammates, opponents, coaches, referees and other staff in competitions. 36　　　　　　　　　　　　　　　　 They shout at teammates and argue with coaches or referees. 　　Children usually learn sportsmanship, good or bad, from adults around them. 37　　　　　　　　　　　　　　　　 If parents and coaches show disrespect to audiences and referees, children will copy such behaviour on the sports field. 　　38　　　　　　　　　　　　　　　　 Some are simple actions, like shaking hands with competitors before games. Others require more courage, for example, praising wonderful moves made by the opposing team. 　　Learning good sportsmanship matters greatly. It helps you develop politeness and respect, which can influence all parts of your life. 39　　　　　　　　　　　　　　　　 Good behaviour at school will gradually turn into good manners in your future work. 　　Try to be a sportsman with good qualities in everything you do! 40　　　　　　　　　　　　　　　　 When others see you understand that winning is not everything, they will focus on more important things: fun, exercise and self-improvement.

One weekend evening, she had a sharp quarrel with her mother over trivial daily matters. Feeling wronged and furious, she rushed out of home without taking any money or phone. Tears blurred her eyes as she walked aimlessly along the quiet street. She had always thought her mother was strict and never truly understood her feelings. After wandering for a long time, hunger overwhelmed her. She stopped in front of a roadside snack stall, staring at the steaming hot dumplings. With no money in hand, she could only sigh helplessly and prepare to leave. 　　The kind stall owner noticed her lonely and upset look and called out gently, “Hi kid, are you hungry? Want a bowl of dumplings?” 　　Sophie lowered her head and replied shyly, “I really want to eat, but I don’t have any money with me.” 　　“It’s fine, it’s on me. Come and sit down,” the owner smiled warmly. 　　Soon a bowl of hot dumplings was served. The warm food comforted her empty stomach, and tears streamed down her face again. 　　Seeing this, the owner asked softly, “Why are you crying, honey?” 　　“I’m just so touched,” Sophie sobbed. “A stranger is willing to treat me to dinner, but my mom always blames me and never gives in to me. She is so unkind to me.” 　　The owner shook his head and smiled patiently. “Think carefully. I only give you a bowl of dumplings, and you are so grateful. But your mother has accompanied you, taken care of you and devoted everything to you since you were born. How many selfless things has she done for you?” 　　Sophie froze on the spot, lost in deep thought. She suddenly recalled her mother’s countless warm moments: getting up early to prepare breakfast, staying up late to accompany her study, tolerating all her bad tempers. She felt extremely ashamed. She was grateful for a stranger’s tiny kindness, but ignored her mother’s long-term selfless love. 　　On the way home, Sophie made up her mind to sincerely apologize to her mother and cherish her family’s love. 注意： 1. 续写词数150左右； 2. 按照格式在答题卡作答。 Para 1: As Sophie approached her house, she slowed down and took a deep, steady breath. Para 2: A gentle voice beside her ear pulled her back from her endless thoughts. 【满分范文】 As Sophie approached her house, she slowed down and took a deep, steady breath. The warm light streaming through the window made her eyes sting. She could vaguely see a familiar figure pacing back and forth in the living room. It was her mother, who must have been anxiously looking for her all night. Thinking of how rudely she had spoken and how selfishly she had run away, Sophie’s heart was filled with deep regret. She gathered up all her courage and gently pushed open the door. A gentle voice beside her ear pulled her back from her endless thoughts. “Where have you been? I was so worried about you,” her mother asked softly, with tiredness and relief in her eyes. Instead of blaming her, she immediately poured a cup of warm water for Sophie. Tears welled up in Sophie’s eyes. She hugged her mother tightly and apologized sincerely. That night, Sophie truly understood that unconditional love from family is the most precious warmth in life, which she would cherish forever. 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司1 / 23 学科网（北京）股份有限公司 $ 2026-2027学年高一必修第一册英语单元自测 Unit 4 Natural Disasters能力提升 学校:___________班级：___________姓名：___________分数：___________ （时间：120分钟，满分：150分） 注意事项： 1. 答卷前，考生务必将自己的姓名、准考证号填写在答题卡上。 2. 回答选择题时，选出每小题答案后，用铅笔把答题卡上对应题目的答案标号涂黑。如需改动，用橡皮擦干净后，再选涂其他答案标号。回答非选择题时，将答案写在答题卡上，写在本试卷上无效。 3. 考试结束后，将本试卷和答题卡一并交回。 第一部分 听力 略（共两节，满分 30 分） 第二部分 阅读（共两节，满分50分） 第一节（共15小题；每小题2.5分，满分37.5分） 阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项，并在答题卡上将该项涂黑。 A 　　Global Youth Vision (GYV) is a Chinese youth-focused organization devoted to global communication.

He always kept tidy and carried a positive attitude toward life, which even made his little naughty acts lovely. 　　He liked talking nonstop in class. I often reminded him that chatting without permission was not allowed. However, what impressed me most was his sincere response every time I corrected his bad behaviour: “Thank you for reminding me, teacher.” At first, I felt confused about his reaction, but gradually I got used to hearing these words many times every day. 　　One Friday, after learning a new knowledge point for a whole week, I found my students felt discouraged and easily annoyed with each other. Therefore, I asked everyone to write down classmates’ names and one warm comment for each classmate. All students handed in their sheets before leaving the classroom. 　　On Saturday, I copied each student’s name on separate paper and collected all the positive comments about them. On Monday, I passed these notes to every student. Some students’ lists covered two full pages. Soon, smiles appeared on everyone’s faces. “I never knew so many classmates like me!” Leo said, “Thank you for arranging this, teacher.” 　　No one talked about these notes in class later. I never learned whether they discussed the words with friends or family members. 　　Years later, I received a phone call from Leo’s parents, informing me of his passing away. I was greatly shocked. Soon a wallet was delivered to me. Inside were worn pieces of notebook paper, repeatedly folded and pasted. I recognized them at once — the list full of kind words his classmates had written for him. At that moment, tears filled my eyes. 24. What can we infer about Leo from the first two paragraphs? A. He liked talking a lot. B. He was unpopular among classmates. C. He ignored the teacher’s suggestions. D. He paid little attention to his appearance. 25. Why did the author ask students to write positive comments for each other? A. To express congratulations. B. To show personal preference. C. To achieve mutual understanding. D. To learn to appreciate others. 26. Which word group can best describe Leo? A. Naughty but creative. B. Gentle but impatient. C. Thankful and respectful. D. Serious and curious. 27. What message does the story convey? A. Classmates’ opinions have little influence on people. B. A teacher’s thoughtful method can positively influence students. C. Academic grades matter most for teenagers. D. Punishment works well to correct students’ mistakes. C 　　As autumn replaces summer, many people long for warm sunshine. When daylight becomes shorter, some people feel low-spirited. This common feeling is known as autumn blues. 　　Autumn blues is just a common seasonal mood change caused by reduced sunlight. However, for some people, this bad mood develops into a serious condition called Seasonal Affective Disorder (SAD). 　　SAD is a type of depression. Its symptoms usually begin in late autumn or early winter and disappear when spring and summer come. People suffering from SAD tend to sleep longer, eat more food, and lose interest in hobbies they once loved. Most patients feel upset, helpless and even hopeless. 　　Experts have not found the exact cause of SAD, but several factors are related to the illness. Researchers from Johns Hopkins University point out that less natural light in autumn and winter may disturb the human body’s biological clock and affect hormone production, such as melatonin and serotonin. These hormones control sleep quality and emotions. Such disorder may lead to depression. 　　There are ways to deal with SAD. Light treatment is widely used and effective. Doctors advise patients to get exposed to natural sunlight or special lighting equipment that copies sunlight. Light therapy helps balance hormones and return to regular daily life. 　　Besides light treatment, healthy lifestyles matter a lot. Keeping regular sleeping hours, taking exercise frequently and keeping balanced diets can ease SAD symptoms. Meanwhile, patients should turn to professional doctors to work out proper treatment plans. 　　According to research from the US National Institute of Mental Health, SAD mostly appears among young adults. Therefore, when you bury yourself in study, remember to walk outdoors to enjoy sunshine and gain energy from nature. 28. What information about SAD is true? A. It generally begins in early autumn. B. It will turn into permanent depression. C. Feeling sad is one of its main symptoms. D. It mainly troubles elderly people. 29. According to Johns Hopkins University, what may cause SAD? A. Unbalanced eating habits. B. Shortage of natural sunlight. C. Irregular sleeping time. D. Lack of physical exercise. 30. What does the underlined word “Handling” in Paragraph 5 mean? A. Searching for. B. Getting rid of. C. Covering up. D. Dealing with. 31. What can we infer from the last paragraph? A. Only young adults suffer from SAD. B. Sunshine outdoors alone can cure SAD completely. C. Outdoor activities and sunlight may help prevent SAD. D. It is never too late to enjoy the beauty of nature. D 　　Gir National Park in western India is the unique natural habitat of Asiatic lions. At the beginning of the 1900s, habitat loss and illegal hunting greatly reduced their population, with fewer than 50 individuals surviving. Over recent decades, protection efforts have achieved results. The number rose to about 670 in 2020. Even so, Asiatic lions are still listed as endangered species. 　　Tracking these lions is one of the biggest difficulties in protecting them. Some wild animals such as tigers and zebras have unique stripe patterns, which help researchers tell individuals apart. But Asiatic lions do not have such clear marks, so researchers need new methods. 　　In 2019, Banerjee, a researcher from India’s National Tiger Conservation Authority, created an AI system that can identify Asiatic lions accurately. This AI tool named SIMBA has been put into practical use. Banerjee says: “It will become a valuable tool for long-term lion observation. It helps forest workers calculate the lion population more precisely. In several years, we can collect plenty of data: the number of male and female lions, birth numbers and death numbers.” 　　However, Banerjee also expresses his concerns. He suggests making strict rules to prevent sensitive wildlife data from being stolen. “The biggest value of SIMBA is helping researchers design monitoring plans, which are key to protecting endangered wildlife. Without proper rules, all protective work may end up useless.” 32. What is the main difficulty in protecting Asiatic lions? A. Tracking the lions. B. Preventing illegal hunting. C. Protecting their living environment. D. Increasing their population size. 33. How does SIMBA offer help to researchers? A. By finding lions’ shelters. B. By tracking other wildlife. C. By watching wildlife poachers. D. By supplying accurate data. 34. What is Banerjee’s attitude towards the AI system? A. It should be popularized worldwide. B. It has already saved endangered animals. C. People should realize its potential risks. D. We should ignore its shortcomings. 35. Which title suits the text best? A. The Biggest Challenge Facing Asiatic Lions B. Ways to Protect Asiatic Lions C. AI Technology Used in Wildlife Protection D. An AI Tool for Protecting Endangered Asiatic Lions 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。选项中有两项为多余选项。 　　Most sports have winners and losers, but winning every match is not the purpose of sports.

One weekend evening, she had a sharp quarrel with her mother over trivial daily matters. Feeling wronged and furious, she rushed out of home without taking any money or phone. Tears blurred her eyes as she walked aimlessly along the quiet street. She had always thought her mother was strict and never truly understood her feelings. After wandering for a long time, hunger overwhelmed her. She stopped in front of a roadside snack stall, staring at the steaming hot dumplings. With no money in hand, she could only sigh helplessly and prepare to leave. 　　The kind stall owner noticed her lonely and upset look and called out gently, “Hi kid, are you hungry? Want a bowl of dumplings?” 　　Sophie lowered her head and replied shyly, “I really want to eat, but I don’t have any money with me.” 　　“It’s fine, it’s on me. Come and sit down,” the owner smiled warmly. 　　Soon a bowl of hot dumplings was served. The warm food comforted her empty stomach, and tears streamed down her face again. 　　Seeing this, the owner asked softly, “Why are you crying, honey?” 　　“I’m just so touched,” Sophie sobbed. “A stranger is willing to treat me to dinner, but my mom always blames me and never gives in to me. She is so unkind to me.” 　　The owner shook his head and smiled patiently. “Think carefully. I only give you a bowl of dumplings, and you are so grateful. But your mother has accompanied you, taken care of you and devoted everything to you since you were born. How many selfless things has she done for you?” 　　Sophie froze on the spot, lost in deep thought. She suddenly recalled her mother’s countless warm moments: getting up early to prepare breakfast, staying up late to accompany her study, tolerating all her bad tempers. She felt extremely ashamed. She was grateful for a stranger’s tiny kindness, but ignored her mother’s long-term selfless love. 　　On the way home, Sophie made up her mind to sincerely apologize to her mother and cherish her family’s love. 注意： 1. 续写词数150左右； 2. 按照格式在答题卡作答。 Para 1: As Sophie approached her house, she slowed down and took a deep, steady breath.

All Grade One students took an active part in the event. Early in the morning, participants gathered at the school gate. After a brief opening speech, we set off cycling along the greenway. During the ride, we enjoyed beautiful natural scenery and called on passers-by to choose green travel. The activity ended with a group photo. The activity was highly praised. It not only built up our bodies but also raised our awareness of environmental protection. More students have realized the importance of living a low-carbon life. 第二节 （满分25分） 【满分范文】 As Sophie approached her house, she slowed down and took a deep, steady breath. The warm light streaming through the window made her eyes sting. She could vaguely see a familiar figure pacing back and forth in the living room. It was her mother, who must have been anxiously looking for her all night. Thinking of how rudely she had spoken and how selfishly she had run away, Sophie’s heart was filled with deep regret. She gathered up all her courage and gently pushed open the door. A gentle voice beside her ear pulled her back from her endless thoughts. “Where have you been? I was so worried about you,” her mother asked softly, with tiredness and relief in her eyes. Instead of blaming her, she immediately poured a cup of warm water for Sophie. Tears welled up in Sophie’s eyes. She hugged her mother tightly and apologized sincerely. That night, Sophie truly understood that unconditional love from family is the most precious warmth in life, which she would cherish forever. 原创精品资源学科网独家享有版权，侵权必究！1 学科网（北京）股份有限公司1 / 2 学科网（北京）股份有限公司 $
