It is hard to imagine what our lives would be like without it. We use electricity for almost every activity in our daily lives, from waking up with an alarm clock to going to bed with a night light. In our homes, electricity powers all kinds of appliances: fridges keep our food fresh, washing machines clean our clothes, air conditioners keep us comfortable, and computers and phones help us connect with the world. Without electricity, we would not be able to cook, clean, or even work from home. Electricity is also vital for schools, hospitals and businesses. Schools use electricity to power computers, projectors and lights, making learning possible. Hospitals rely on electricity to run life-saving medical equipment, such as ventilators and X-ray machines. Businesses use electricity to power factories, offices and shops, keeping the economy running. However, electricity is not unlimited. Most of the electricity we use comes from burning fossil fuels, which causes air pollution and climate change. To protect the environment, we need to save electricity and use renewable energy sources, such as solar and wind power. Simple actions, like turning off lights when leaving a room, using energy-saving appliances, and unplugging chargers, can help us reduce our electricity use and protect the planet. 1. Why is electricity important in our daily lives? A. Because it is easy to produce. B. Because it powers almost all our daily activities and appliances. C. Because it is free for everyone. D. Because it is a new invention. 2. What do fridges do with electricity? A. They clean our clothes. B. They keep our food fresh. C. They keep us cool in summer. D. They help us connect with the world. 3. Why do we need to save electricity? A. Because electricity is unlimited. B. Because most electricity comes from fossil fuels, which cause pollution. C. Because electricity is very expensive. D. Because we don’t need much electricity. 4. Which of the following is a way to save electricity? A. Leave lights on when leaving a room. B. Use energy-saving appliances. C. Keep chargers plugged in all the time. D. Use air conditioners 24 hours a day. 5. What is the main idea of the passage? A. The history of electricity. B. How to produce electricity. C. The importance of electricity and how to save it. D. The dangers of electricity. B Electrical Safety Rules Electricity is very useful, but it can also be very dangerous if we don’t use it correctly. Every year, thousands of people are injured or even killed because of electrical accidents. To stay safe, we must follow these important safety rules: First, never touch electrical appliances, sockets or switches with wet hands. Water is a good conductor of electricity, and it can cause a serious electric shock. Always make sure your hands are dry before touching anything electrical. Second, never put anything other than a plug into a socket. Sticking fingers, pens or other objects into sockets can cause electric shock and fire. Keep sockets covered if you have small children at home. Third, never fly kites or climb trees near power lines. Power lines carry high-voltage electricity, and if a kite or a tree branch touches them, it can cause a deadly electric shock. Always stay at least 10 meters away from power lines. Fourth, never overload sockets. Plugging too many appliances into one socket can cause overheating and fire. Use a power strip with a surge protector if you need to plug in multiple devices. Finally, if there is an electrical fire, never use water to put it out. Water conducts electricity, and it can make the fire worse. Use a fire extinguisher or call the fire department immediately. By following these rules, we can use electricity safely and avoid accidents. Remember: safety first when using electricity! 6. Why can’t we touch electrical appliances with wet hands? A. Because water will make the appliances dirty. B. Because water is a good conductor of electricity, which can cause electric shock. C. Because water will damage the appliances. D. Because wet hands are slippery. 7. What should we do if we have small children at home? A. Let them play with sockets. B. Keep sockets covered to prevent accidents. C. Put objects into sockets to show them. D. Leave sockets open for easy use. 8. Why can’t we fly kites near power lines? A. Because kites can get stuck on power lines. B. Because power lines carry high-voltage electricity, which can cause deadly shock. C. Because kites can damage power lines. D. Because power lines are ugly. 9. What should we do if there is an electrical fire? A. Use water to put it out. B. Use a fire extinguisher or call the fire department. C. Ignore it and let it burn. D. Pour oil on the fire. 10. What is the main purpose of the passage? A. To introduce different ways of producing electricity. B. To explain the importance of electricity. C. To teach people electrical safety rules to avoid accidents. D. To show the dangers of electricity. 四、任务型阅读（共 5 小题，每小题 2 分，满分 10 分） 阅读下面短文，根据短文内容完成句子。 Electricity is a powerful and useful resource, but it can also be dangerous if not used properly. To stay safe and save energy, we should follow some simple rules in our daily lives. First, always turn off electrical appliances when you are not using them. This not only saves electricity, but also prevents overheating and fire. For example, turn off the lights, TV and computer when you leave a room. Second, never touch electrical devices with wet hands. Water conducts electricity, and it can cause a serious electric shock. Always dry your hands before touching switches, sockets or appliances. Third, use renewable energy sources to produce electricity, such as solar power and wind power. These sources are clean, environmentally friendly and will never run out. Installing solar panels on your roof is a great way to produce your own electricity and reduce your carbon footprint. Fourth, never overload sockets. Plugging too many devices into one socket can cause overheating and fire. Use a power strip with a surge protector if you need to connect multiple devices. By following these rules, we can use electricity safely, save energy, and protect the environment. Remember: every small action counts when it comes to saving electricity and staying safe. 1. We should turn off electrical appliances when not using them to save electricity and prevent ______. 2. Never touch electrical devices with wet hands, because water ______ electricity and can cause electric shock. 3. Solar power and wind power are ______ energy sources, which are clean and will never run out. 4. Plugging too many devices into one socket can cause ______ and fire. 5.
