It can store large amounts of data, recall facts within seconds, and sort out complex knowledge in simple ways. As AI grows smarter, a common question appears: in such a convenient era(时代), do humans still need strong memory? The answer is yes. Although AI performs well in storing information, it can’t replace human memory. AI only offers passive(被动的) answers. True understanding and creative thinking depend on the knowledge we keep in our own brains. ★ When we memorize basic rules, words and concepts, we build our own knowledge system. This allows us to analyze problems, make connections and form new ideas. If we rely totally on AI, we only receive ready-made results without real thinking. Gradually, our ability to learn and judge will become weaker. Training memory also keeps our brains active and sharp. Like physical exercise strengthens the body, regular memorization improves our cognitive speed and concentration. Many people become lazy thinkers because they get used to AI support. They lose the patience to remember and the ability to think independently. Moreover, human memory carries unique value that AI can never own. Machines record cold data, but humans store experiences, emotions and growth moments. These personal memories shape our thoughts and personalities. In a word, AI is a powerful learning assistant, not a substitute(替代物) for our brains. In the AI era, memory remains an important skill. Only by keeping independent memory practice can we maintain clear thinking, effective learning and personal creativity. ( ) 1. What will happen if we fully depend on AI? A. We will get real thinking behind ready-made results. B. Our learning and judging ability will become weaker. C. We can form new ideas more easily. D. We will build our own knowledge system quickly. ( ) 2. Which sentence can be put in ★ ? A. Memory serves as the base of all learning. B. AI helps students finish their homework quickly. C. People can improve memory by doing sports. D. AI can create new ideas for learners. ( ) 3. What can we infer from Paragraph 5? A. AI is able to store people’s feelings and life experiences. B. Human personalities are influenced by personal memories. C. Machines can record warm and special moments for humans. D. Cold data from machines can shape people’s thoughts. ( ) 4. Which of the following is TRUE? A. Regular memorization is bad for our cognitive speed. B. AI can sort out complex knowledge in difficult ways. C. Memory training helps keep our brains active and sharp. D. AI can work as a replacement for human brains. ( ) 5. What is the main idea of the passage? A. AI can help students solve all kinds of learning problems. B. AI can store people’s emotional experiences and growth moments. C. People should stop using AI to protect their memory. D. Human memory is still an important skill in the AI era. 【拓展提升】 六、综合填空。 阅读下面短文，根据上下文或括号内单词等提示，在空白处填入适当的单词或括号内单词的适当形式。 Many great learners do not depend on 1. ________(nature) talent.
