The first morning, I woke to soft music playing from the ceiling. “Good morning, Lucy. Today's temperature is 28℃,” said a gentle voice. I jumped—it was the AI speaker, adjusting the curtains automatically. At breakfast, Dad's phone buzzed. “The fridge says we're low on milk,” he laughed, showing an alert from the smart refrigerator. After school, Mom demonstrated security features: door sensors glowed red if unlocked, and cameras sent real-time videos to her watch. But one rainy night,chaos struck. Lights flickered wildly, and the thermostat (恒温器) suddenly blowed out cold air. “Hackers!” Mom gasped, checking her app. We huddled under blankets until technicians fixed the system.

The AI assistant greeted me with a cheerful voice: “Ready to conquer math?” During algebra homework, I whispered, “Solve question 5,” and a holographic (全息的) projection danced above my desk, breaking down equations step-by-step. My homework scores soared, but Mr.Li noticed my confusion in class. “Lucy, explain this formula (方程式),” he demanded. My mind went blank as my classmates langhed under their breath. One rainy evening, disaster struck. Brainy Bot's screen flickered red: “System overload. Shutting down..” My final exam was in 12 hours! Panicking, I grabbed a pencil and notebook. Mom's old advice echoed: “Draw diagrams to visualize problems.” Trembling, I drew geometric shapes quickly, shading areas with colored markers. To my surprise, the patterns revealed hidden logic. The next day, I scored 85%—higher than any AI-assisted grade! Now, I balance tech and tradition. Brainy Bot checks answers,but my handwritten notes fill journals. As Mr.Li says, “Tools are lifeless without your spark.” Task 1: Answer the questions. 1. How did Brainy Bot initially help the narrator? 2. What caused the narrator's panic before the exam? 3.
