First, consider your child's age and developmental level. An app that is perfect for a 10-year-old may be too advanced or too simple for a 6-year-old. 2 Look for apps that match your child's current skills and interests, and that can grow with them as they learn. __3 The best educational apps are interactive and engaging, not just a series of passive quizzes or videos. They should encourage critical thinking, problem-solving, and creativity. Apps that allow children to create something, whether it's a story, a drawing, or a simple program, are particularly beneficial. Check the reviews and ratings from other parents and educators. 4 Look for apps that have received positive feedback from both parents and teachers, and that have won awards or recognition from educational organizations. Finally, test the app yourself before letting your child use it. Spend 10-15 minutes playing with it to understand how it works, what content it contains, and whether it's appropriate for your child. 5 This will also help you understand how to support your child's learning when they use the app. A. Choose apps that offer active learning experiences. B. Many educational apps claim to be "research-based" but actually have little educational value. C. Reading reviews can give you a good idea of the app's strengths and weaknesses. D. Apps should be both educational and entertaining to hold children's attention. E. Pay attention to the recommended age range provided by the app developer. F. Not all so-called "educational" apps actually provide high-quality learning experiences. G. This will help you identify any potential issues, such as inappropriate content or excessive advertising. 二、书面表达 假设你是校英文报的编辑，最近收到很多读者来信询问如何合理使用手机APP。请你写一篇短文，给同学们提一些合理使用APP的建议。 内容包括： 1. 分析APP使用的利弊； 2. 提出2-3条合理使用的建议； 3. 呼吁大家理性使用APP，平衡虚拟与现实生活。 注意： 1. 词数100左右； 2. 可以适当增加细节，以使行文连贯。 1、 阅读理解（2024年新课标I卷真题改编·科技教育主题） With the rapid development of digital technology, educational apps have become an important part of modern teaching and learning. A 2024 survey by the Ministry of Education showed that over 85 percent of primary and secondary schools in China now use educational apps to support classroom teaching and after-school learning. These apps offer a wide range of functions: language learning apps provide pronunciation correction and interactive speaking practice; math apps offer step-by-step problem-solving explanations and personalized exercises based on students' performance; and science apps use virtual reality technology to simulate experiments that are too dangerous or expensive to conduct in real classrooms. For students, educational apps provide learning opportunities that go beyond the traditional classroom. Students living in remote areas can now access high-quality teaching resources from top schools across the country. They can also learn at their own pace, replaying explanations as many times as needed until they fully understand the content. However, the popularity of educational apps has also raised concerns. Some parents worry that excessive screen time may harm their children's eyesight and reduce their ability to concentrate. There are also concerns about data privacy, as many apps require users to provide personal information such as name, age, and school. To address these issues, the Ministry of Education issued new regulations in 2025 requiring all educational apps to pass strict content and security reviews before they can be used in schools. The regulations also limit the amount of time students can spend on educational apps per day and require developers to protect users' personal information according to national data security standards. 1. What is the main idea of the second paragraph? A. Educational apps have various functions. B. Science apps use VR technology for experiments. C. Language apps help improve students' pronunciation. D. Math apps provide personalized exercises for students. 2. What is one benefit of educational apps for students in remote areas? A. They can attend virtual classes in top schools. B. They can access high-quality teaching resources. C. They can participate in national competitions. D. They can communicate with students in cities. 3. What does the underlined word "they" in paragraph 3 refer to? A. Students B. Educational apps C. Teaching resources D. Top schools 4. Why did the Ministry of Education issue new regulations on educational apps? A. To promote the development of educational apps. B. To limit the use of educational apps in schools. C. To ensure the safe and healthy use of educational apps. D. To encourage schools to use more educational apps. 二、语法填空（2025年全国I卷真题改编·科技类说明文） Mobile apps have changed the way people access public services in China. In recent years, a number of "government service apps" 1 (develop) to help people handle daily affairs more conveniently. With these apps, people can do things like paying utility bills, 2 (apply) for ID cards, and making doctor's appointments without having to visit government offices in person. This not only saves time and energy 3 also improves the efficiency of public services. One of the most popular apps is the "National Government Service Platform", 4 has over 800 million registered users.

First, consider your child's age and developmental level. An app that is perfect for a 10-year-old may be too advanced or too simple for a 6-year-old. 2 Look for apps that match your child's current skills and interests, and that can grow with them as they learn. __3 The best educational apps are interactive and engaging, not just a series of passive quizzes or videos. They should encourage critical thinking, problem-solving, and creativity. Apps that allow children to create something, whether it's a story, a drawing, or a simple program, are particularly beneficial. Check the reviews and ratings from other parents and educators. 4 Look for apps that have received positive feedback from both parents and teachers, and that have won awards or recognition from educational organizations. Finally, test the app yourself before letting your child use it. Spend 10-15 minutes playing with it to understand how it works, what content it contains, and whether it's appropriate for your child. 5 This will also help you understand how to support your child's learning when they use the app. A. Choose apps that offer active learning experiences. B. Many educational apps claim to be "research-based" but actually have little educational value. C. Reading reviews can give you a good idea of the app's strengths and weaknesses. D. Apps should be both educational and entertaining to hold children's attention. E. Pay attention to the recommended age range provided by the app developer. F. Not all so-called "educational" apps actually provide high-quality learning experiences. G. This will help you identify any potential issues, such as inappropriate content or excessive advertising. 答案与解析： 1. F 前句提到家长很难选择合适的教育类APP，F选项“并非所有所谓的‘教育类’APP都能提供高质量的学习体验”承接上文，引出后文的选择建议。 2. E 本段讲要考虑孩子的年龄和发展水平，E选项“关注APP开发者提供的推荐年龄范围”符合本段主旨。 3. A 本段讲最好的教育APP是互动性和参与性强的，A选项“选择能够提供主动学习体验的APP”为本段主题句。 4. C 前句提到要查看其他家长和教育者的评价，C选项“阅读评价可以让你很好地了解APP的优缺点”承接上文。 5. G 前句建议家长自己先测试APP，G选项“这会帮助你发现潜在问题，比如不合适的内容或过多的广告”承接上文，说明自己测试的好处。 二、书面表达 假设你是校英文报的编辑，最近收到很多读者来信询问如何合理使用手机APP。请你写一篇短文，给同学们提一些合理使用APP的建议。 内容包括： 1. 分析APP使用的利弊； 2. 提出2-3条合理使用的建议； 3. 呼吁大家理性使用APP，平衡虚拟与现实生活。 注意： 1. 词数100左右； 2. 可以适当增加细节，以使行文连贯。 参考范文： Use Apps Wisely Nowadays, mobile apps have become an important part of our daily life. They bring us great convenience, helping us with study, communication, and entertainment. However, excessive use of apps, especially social media and game apps, can also lead to reduced study efficiency, sleep loss, and even social isolation in real life. To use apps wisely, first, we should prioritize educational and productivity apps over entertainment ones. Second, set a time limit for app use every day and stick to it strictly. Finally, never share personal information on unknown apps to protect our privacy. Let's use apps in a more rational way and maintain a healthy balance between the digital world and real life. 1、 阅读理解（2024年新课标I卷真题改编·科技教育主题） With the rapid development of digital technology, educational apps have become an important part of modern teaching and learning. A 2024 survey by the Ministry of Education showed that over 85 percent of primary and secondary schools in China now use educational apps to support classroom teaching and after-school learning. These apps offer a wide range of functions: language learning apps provide pronunciation correction and interactive speaking practice; math apps offer step-by-step problem-solving explanations and personalized exercises based on students' performance; and science apps use virtual reality technology to simulate experiments that are too dangerous or expensive to conduct in real classrooms. For students, educational apps provide learning opportunities that go beyond the traditional classroom. Students living in remote areas can now access high-quality teaching resources from top schools across the country. They can also learn at their own pace, replaying explanations as many times as needed until they fully understand the content. However, the popularity of educational apps has also raised concerns. Some parents worry that excessive screen time may harm their children's eyesight and reduce their ability to concentrate. There are also concerns about data privacy, as many apps require users to provide personal information such as name, age, and school. To address these issues, the Ministry of Education issued new regulations in 2025 requiring all educational apps to pass strict content and security reviews before they can be used in schools. The regulations also limit the amount of time students can spend on educational apps per day and require developers to protect users' personal information according to national data security standards. 1. What is the main idea of the second paragraph? A. Educational apps have various functions. B. Science apps use VR technology for experiments. C. Language apps help improve students' pronunciation. D. Math apps provide personalized exercises for students. 2. What is one benefit of educational apps for students in remote areas? A. They can attend virtual classes in top schools. B. They can access high-quality teaching resources. C. They can participate in national competitions. D. They can communicate with students in cities. 3. What does the underlined word "they" in paragraph 3 refer to? A. Students B. Educational apps C. Teaching resources D. Top schools 4. Why did the Ministry of Education issue new regulations on educational apps? A. To promote the development of educational apps. B. To limit the use of educational apps in schools. C. To ensure the safe and healthy use of educational apps. D. To encourage schools to use more educational apps. 答案与解析： 1. A 主旨大意题。第二段主要介绍了教育类APP的各种功能：语言学习、数学练习、科学实验模拟等，A选项最全面。 2. B 细节理解题。根据第三段"Students living in remote areas can now access high-quality teaching resources from top schools across the country."可知答案为B。 3. A 代词指代题。根据前文"Students living in remote areas can now access high-quality teaching resources... They can also learn at their own pace"可知they指代的是学生。 4. C 推理判断题。根据最后一段可知，教育部出台新规是为了解决屏幕时间过长、数据隐私等问题，确保教育类APP的安全健康使用，故选C。 二、语法填空（2025年全国I卷真题改编·科技类说明文） Mobile apps have changed the way people access public services in China.
