What can we learn from the first two paragraphs？（　　） A. Only workers worry about losing jobs. B. Machines perform better than humans in all fields. C. “Machine replacement” anxiety appears in every era. D. The development of technology causes “machine replacement” anxiety. 解析：细节理解题。根据第一段和第二段中第一句可知，技术的发展引起了“机器取代人”的焦虑。 √ 目 录 英语·选择性必修第四册（BSD） 9. What causes the decline in the need for workers in some jobs？（　　） A. The increase in labor costs. B. The lack of managerial skills. C. The emergence of new industries. D. The improvement of machines’ precision. 解析：　细节理解题。根据第五段最后一句可知，机器精度的提高 导致对某些工作岗位工人的需求下降。 √ 目 录 英语·选择性必修第四册（BSD） 10. What can be inferred about the future job market from the text？ （　　） A. Human jobs will be completely replaced by machines. B. Jobs requiring creativity will be more valuable. C. Only technical jobs will remain in the market. D. Machine maintenance jobs will disappear. 解析：推理判断题。根据倒数第二段第二句至段尾可推知，在未来就业市场中，需要创造力的工作将更有价值。 √ 目 录 英语·选择性必修第四册（BSD） 11. Which of the following can be the best title for the text？（　　） A. The Irreplaceability of Humans B. The All-powerful Machines C. The Rapid Rise of AI D. The End of Human Labor 解析：标题归纳题。文章主要讨论了人工智能和机器人是否能真正取代人类的问题，并指出虽然机器在某些方面已经超越了人类，但它们无法取代人类在某些方面的独特品质。A项（人类的不可替代性）为文章最佳标题。 √ 目 录 英语·选择性必修第四册（BSD） Ⅱ.阅读七选五 　　（2025·山西大同期末）What is it that allows Steve Jobs and Elon Musk to innovate so consistently？ 12.（　　） It’s about trying to step outside of the mental restrictions we impose （强加于） upon ourselves to attempt to look at a problem in a new light.Being creative allows yourself to do things， experience things or consider things in unfamiliar ways.13. （　　） 目 录 英语·选择性必修第四册（BSD） 　　Be curious. 　　Creativity at work is not limited only to what goes on in the workplace.If you want to be a creative and innovative individual， you need to broaden your horizons.14.（　　） This can help you learn about as many fields of knowledge as you can.If you have a too narrow outlook， you won’t be able to break out of your limited world view and make the connections you need to have original thoughts. 目 录 英语·选择性必修第四册（BSD） 　　15.（　　） 　　If creativity is all about having different perspectives and viewpoints， then it must make sense to hire people from different backgrounds and with different experiences.If you’re the boss， don’t simply hire people in your own image.If you populate your office with your clones and your company with like-minded people， creativity will suffer.A much better hiring policy is to try to create a team as diverse as possible.When it comes to discussions and coming up with new ideas， you will gain the rewards. 目 录 英语·选择性必修第四册（BSD） 　　Surround yourself with inspiration. 　　Always be on the lookout for new and exciting material and decorate your workspace with whatever you find.16.（　　） It’s up to you.Make sure you keep replacing everything too — it will keep your space fresh， and this， in turn， will keep your mind fresh.Above all， don’t let your environment become dull and boring. A. Build a diverse team. B. Organize brainstorming sessions in your team. C. Try to step outside of the world you are familiar with. 目 录 英语·选择性必修第四册（BSD） D. Here are a few things to help you be more creative at work. E. Creativity is about trying to see things from a different angle. F. It’s amazing that a simple change of scenery can help your creativity flow again. G. It could be newspaper headlines， inspiring sentences， objects， photos or anything else. 语篇解读：本文是一篇说明文。文章就如何培养创造力给出了三条 建议。 语篇解读：本文是一篇说明文。文章就如何培养创造力给出了三条 建议。 目 录 英语·选择性必修第四册（BSD） 12.

C　根据上文可知，空处应介绍拓宽视野的做法。C项（试着走出 你所熟悉的世界）呼应上文的“不仅仅局限于工作场所”。 目 录 英语·选择性必修第四册（BSD） 15. A　本段主要介绍了要创建一个多样化的团队。A项（建立一个多 元化的团队）适合作为段落小标题。 16. G　根据上文可知，空处应介绍一些能找到的装饰物。G项列举了 可以用来激发灵感的事物。 目 录 英语·选择性必修第四册（BSD） $
