One misty evening, as we drove on a narrow and winding cliff-side road, Alex, full of confidence, turned on the self-driving mode. At that time, I was nervous, holding the armrest tightly, while Alex casually scrolled (滚屏) through social media, completely ignoring the increasingly dangerous road conditions. Suddenly, a strong deer appeared in the headlights. At that critical moment, the car's sensors, which had been failing unnoticed, went wrong. Instead of braking, the car sped towards the deer. Alex, realizing the danger at the last second, tried to reach for the steering wheel, but it was too late. The car crashed into the deer, and we were shaken hard. Surprisingly, the deer ran into the woods, unhurt. We sat in the damaged car, shocked. 返回导航 This accident made me reflect on technology's issues. In healthcare, AI robots, sometimes, for speed, misread symptoms, causing incorrect diagnoses. In education, speed-focused AI graders may score essays by keywords, missing emotional depth in student stories—like a child writing of sadness, whose words become data, not cries for sympathy. In other words, AI prioritizes speed over correct diagnosis or students' emotional expressions. Philosopher Sherry Turkle's words make sense—“We're sacrificing exactness and sympathy for efficiency.” 返回导航 But this doesn't mean we should reject technology. We should use it carefully and wisely. Just like a compass helps a sailor but doesn't replace his skills, technology should help our judgment, not take over. Doctors could use AI technology as an extra opinion, and compare it with their own knowledge. Teachers can use AI technology to analyze student data and adjust lessons with their own insights, and not to let algorithms (算法) control teaching. 返回导航 That night, standing by the broken car, I realized that technology, for all its power, depends on us. Over-reliance on it weakens our ability to adapt and think. In the end, we, not machines, should shape the future. 返回导航 　 How did the author and Alex feel during the drive before the accident? _________________________________________________________ 　 What contributed to the accident of the self-driving car according to Paragraph 2? ____________________________________________________ 　 What does the underlined sentence mean in Paragraph 3? _____________________________________________________________________________________________________________________ 1 2 3 The author felt nervous and Alex felt relaxed. The car's sensors failure and Alex's inattention. We are giving up accuracy and understanding of others for speed. / We are choosing speed over accuracy and understanding of others. 返回导航 　 What is the main idea of Paragraph 4? ___________________________________________________________ 　 Do you consider AI technology as a tool to make important decisions in our lives? Please explain in your own words. ____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________ 4 5 We should use technology carefully and wisely. No. AI lacks human judgment and sympathy, which is crucial in decision-making. It should be human beings who make their own decisions in their lives./Yes. AI can offer data-driven insights to enhance the quality of important decisions. 返回导航 $
