I began with simple questions in class, and every evening I practiced speaking in front of the mirror. Little by little, my voice became steady. At the end of the term, I even gave a speech in front of the whole class confidently. Through this experience, I have learned that I am braver than I thought. Difficulties are not walls but steps. Growing up means facing problems with courage, and every small step makes me stronger. 学科网（北京）股份有限公司 $ 苏州胥口中学2026初三英语 期中复习卷（一） 第一部分 完形填空（共10小题；每小题1分，满分10分） 请认真阅读下面短文，从短文后各题所给的 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。 Love, joy and the warm feeling of getting together don’t cost a thing.

They sail around the world. They have all kinds of adventures (冒险). This wasn’t true hundreds of years ago. Back then, women were expected to stay home. But that didn’t stop these three women from taking off and doing big things. Jeanne Baret (1740—1807): Baret was a French scientist. She studied plants. And she was the first woman to sail around the world. In 1766, Baret wanted to set sail with a group of scientists. But they were all men. Women weren’t allowed to travel on French navy ships. So Baret pretended (假装) to be a man. And she sailed away. Lady Hester Stanhope (1776—1839): Stanhope was from England. She wanted to travel. She traveled throughout the Middle East by herself. And she led an archeological (考古的) dig there. She was the first woman to do this. Nellie Bly (1864—1922): Bly was a reporter. In 1887, she wrote a story about hidden problems at a hospital. She dressed up like a patient at the hospital. Then she wrote an alarming six-part report. The story made Bly well-known. It also led the way for other women reporters. Two years later, Bly set a world record. She traveled around the world in seventy-two days! 11. The passage is probably from the ________ section of a magazine. A. People B. Science C. Health D. News 12. According to the passage, ________ had to dress up like a man in order to sail away. A. Red Bank B. Nellie Bly C. Lady Hester Stanhope D. Jeanne Baret 13. If you are retelling this passage, it is the most important to tell others that ________. A. women today have all kinds of adventures B. women could do great things even centuries ago C. Jeanne Baret was the first woman to sail around the world D. the fact that Nellie Bly traveled around the world in seventy-two days made her famous B Pingshu, a traditional Chinese storytelling art, has a history dating back to the Qing Dynasty. Performers usually tell stories in teahouses or small theaters, attracting listeners with their voices and gestures. To learn Pingshu well, artists need years of training. Most of them learn by studying under experienced performers. As one famous artist, Yuan Kuocheng, said, Pingshu is “both mental and physical work.” Performers must memorize long stories and add their own words to make the old stories more attractive. They also need to understand the deeper meanings of the stories and share their thoughts with the listeners. During performances, artists stand behind a table. They use tools like a folding fan and a wooden block called Xingmu. The fan helps act out scenes, such as “drawing a sword (剑).” The Xingmu is knocked on the table to mark the start of the story or to highlight exciting moments. Modern technology has brought both challenges and chances to Pingshu. Since young people today prefer online entertainment, technology allows artists to record their performances. These recordings can be shared widely, helping more people discover Pingshu. Digital methods also protect this art for future people. More often than not, those who listen to Pingshu stories belong to older generations (辈). While most young people spend hours online, a small number still find value in Pingshu, drawn by its cultural richness and storytelling traditions. In summary, Pingshu is not just entertainment — it carries Chinese culture and wisdom. Through stories, performers connect the past with the present, offering listeners both fun and life lessons. 14. What can we infer from the second paragraph? A. Pingshu artists can master the skill within a few months. B. Memorizing stories is less important than physical gestures. C. Learning Pingshu requires both time and guidance from experts. D. Performers need to create completely new stories to attract today’s listeners. 15. What tool is NOT needed during a Pingshu performance? A. A folding fan to act out scenes. B. A wooden block to mark key moments. C. A table to stand behind while performing. D. A microphone to make their voices louder. 16. Which group will most likely attend Pingshu performances? A. Teenagers who prefer online short videos. B. Older people and some young adults who value traditional culture. C. Foreign tourists visiting modern theaters. D. Children learning to play musical instruments. 17. What is modern technology’s influence on Pingshu? A. It allows artists to perform without live listeners. B. It reduces the need for performers to memorize stories. C. It spreads Pingshu to more people and protects its future. D. It forces performers to use digital tools during shows. C One of the best parts of autumn is its beautiful colors. Normally green leaves turn into orange, yellow, red and finally brown. This is called “leaf phenology”, and many people look forward to it every year. However, because of climate change, autumn is changing. According to a study that came out earlier this year, the season length is growing. It is taking longer for leaves to change their colors. And this is not the only way that climate change is ruining the season. “Trees are holding onto their leaves longer,” explained Dr. Diamond, a senior climate scientist. “In my own neighborhood, I can remember that the leaves would drop a lot sooner 20 years ago than they do now. This is a personal experience, but research actually supports what we’re seeing.” Climate change isn’t just causing the leaves to change later. We can also expect later frosts (霜) according to Dr. Mann, a professor of the University of Pennsylvania. Mann said, “That means pests stay active for a longer time in autumn, leading to a greater health risk to human beings.” If there is any good news at all, though, we may be able to slow down this development. Mann pointed out that if humans limited the carbon emissions (限制碳排放), they could still stop the worst effects (影响) of climate change from hitting them during the autumn months. “A new study recently suggests that surface warming will possibly stop after carbon emissions reach zero,” Mann noted in Live Science recently. Autumn is such a wonderful season — whether it’s the golden leaves covering the grasslands in North China or the ginkgo trees (银杏树) dropping their yellow leaves in our schoolyard, it’s a gift we should keep. The beautiful autumn we protect today may be the sweet memory we will hold tomorrow. 18. Which is the effect of climate change on autumn? A. The season length is becoming shorter. B. Leaves are changing their colors and falling later. C. There are more frosts in autumn. D. Pests are no longer active. 19. What does the word “ruin” most likely mean in the passage? A. Cause damage. B. Improve greatly. C. Become more colorful. D. Change completely. 20. What does the underlined phrase “this development” refer to? A. The beautiful autumn scenery in people’s lives. B. Dr. Diamond’s memories of the autumn before. C. The autumn changes because of climate change. D. Dr. Mann’s advice on stopping carbon emissions. 21. What’s the purpose of the passage? A. To call for actions against climate change. B. To describe the beautiful colors of autumn. C. To talk about the effects of autumn changes. D. To explain the research about leaf phenology. D When winter arrived, the porcupine looked for somewhere nice and warm to live. He ran into the woods, looking around for a place. First, he came to a fallen tree trunk. “This looks like a suitable place!” he said, digging a hole in its side. But when he poked his head in, he heard “You can’t stay here. It’s our home, and breakfast, lunch and dinner!” said hundreds of tiny termites (白蚁). The porcupine apologized and backed away. “Now, where can I go?” he wondered. Then he found a space under a thick bush that seemed to be protected from the wind, so he tried crawling in there. “Hey!” hissed the lynx (猞猁), showing her sharp paws. “This is my place, and don’t you forget it!” The porcupine went away in a hurry — he didn’t want any trouble. The poor porcupine was really getting worried. “I might freeze if I don’t find somewhere to stay soon!” he said, his teeth chattering. A snake overhead heard the porcupine and felt sorry for him. She poked her head out of her hole and said, “Would you like to stay in here with me? My home is quite small, but I’m sure we can both fit!” The porcupine was ever so thankful. He pushed his way into the snake’s narrow home. “This is so nice!” he said. “How kind of you to let me in!” However, when the snake tried to get to sleep, she found it impossible to get into a comfortable position. Twist and turn as she might, she was always getting hurt by the porcupine’s spines. “Can you move over a bit?” she asked. The porcupine tried, but it didn’t help! They both spent an uneasy night in the little burrow and hardly slept at all. “I really wanted to help the poor porcupine,” the snake thought, “but I wish I’d never invited him in.” The porcupine was feeling just as upset. When morning came, he cleared his throat and said, “I’m sorry that things are so uncomfortable, especially as you have been so kind. I think I have an idea, if you agree!” The snake was still painful and tired from her sleepless night, so she just nodded. With his paws, the porcupine began scratching (刨) at the hole’s walls. As the snake watched in wonder, the porcupine dug out an extra room that was just the right size for him. “There you are!” he said in a satisfied voice. “Now there is plenty of room for both of us!” The snake and the porcupine shared that burrow all winter. It was warmer with the two of them in it, and there was enough space for both animals to sleep comfortably. The snake enjoyed the stories the porcupine told, and the porcupine was impressed by the snake’s skills at finding food. Their unlikely friendship made winter less lonely for both of them. “I’m glad I let you in!” the snake hissed, “It’s really nice to share my home!” 22. How many times had the porcupine tried before being invited by the snake? A. Once. B. Twice. C. Three times. D. Four times. 23. How did the snake’s feelings change? A. scared→helpless→curious B. interested→nervous→calm C. worried→thankful→pleased D. sorry→uncomfortable→happy 24. Which sentence in the story shows the porcupine’s return for the snake’s kindness? A. He pushed his way into the snake’s narrow home. B. He ran into the woods, looking for a place. C. The porcupine went away in a hurry — he didn’t want any trouble. D. With his paws, the porcupine began scratching at the hole’s walls. 25. Which saying best expresses the theme of this story? A. When we give, we receive. B. Home is where the heart is. C. A miss is as good as a mile. D. Many hands make light work. 第三部分 信息还原（共5小题；每小题1分，满分5分） 请认真阅读下面短文，从短文后的选项中选出能填入空白处的最佳选项，选项中有两项为多余选项。 Have you ever been in trouble and wanted to get away?

We choose fast living because we think we have no control of time. We try to do as much as we can each day, finishing tasks on our to-do lists. Living a busy life makes us feel like we never have enough time. We think in a way that focuses on speed, and we value doing more rather than doing things well. For a long time, we think speed means being productive and successful, so we keep hurrying around to do all things. However, from time to time, we find ourselves in a predicament (困境) that no matter how fast we go, we never seem to be quick enough to catch up with our endless tasks and goals. The Slow Movement thinks that the answer to our predicament is not to live faster, but to learn how to live slower. The movement began with the Slow Food Movement, which was set up in 1986. It believed that we should fight against fast-food restaurants, protect traditional cooking, and encourage people to enjoy preparing and eating food. The belief finally spread from the Slow Food Movement to other parts of life. In 1999, it helped create Cittaslow — a group focused on slowing down life in cities. This belief of slowing down quickly began to influence areas like work, travel, fashion, and living in general. The main idea of the Slow Movement is to value quality over quantity (数量). Slow living is a lifestyle based on the Slow Movement. Its goal is to free us from endless rush that stops us from enjoying moments of rest. Slow living tells us to live each moment with full attention and give everything the time it requires, instead of trying to do as many things as we can every minute. Today, lots of people are drawn to the idea of the Slow Movement because social media spreads the many good points of living slowly. 54. Why do we choose fast living? ________________________________________________________________ 55. According to the Slow Movement, what is the answer to our predicament? ________________________________________________________________ 56. Which lifestyle do you prefer, fast living or slow living? Why? ________________________________________________________________ ________________________________________________________________ 第七部分 书面表达（共1题，满分25分） 青春成长，步履跌宕。步入初三，我们在蜕变中遇见各类成长难题，也在直面困境的途中慢慢读懂自己。请以 “Growing up with ______” 为题，补全标题，结合自身经历写一篇短文，内容包括： 1. 你遇到的困难或困扰； 2. 你如何面对和解决它； 3. 在这个过程中你对自己有什么新认识； 4. 你的成长感悟。 注意： 1. 词数100左右； 2. 内容需涵盖所有要点，可适当发挥； 3. 照抄试卷中的语篇内容不得分； 4. 文中不得出现真实校名和姓名等信息。 Growing up with ______ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ ________________________________________________________________________ 学科网（北京）股份有限公司 $
