In 2019，independent research organization Data & Society studied how automation is being integrated in farm management and grocery stores.Counter to the popular belief that the technology was reducing the need for human labor，researchers Alexandra Mateescu and Madeleine Clare Elish discovered that introducing new devices was mostly changing the nature of the work.For example，automated checkout machines kept employees busy，because they were assisting confused customers， troubleshooting machines，and taking on other tasks to ensure their smooth operation in the store.Most importantly，Mateescu and Elish discovered that the new tasks，which helped accommodate and employ the “automated” technology，were often undervalued or even invisible. The important thing to understand is that the current deskilling and devaluing of labor isn’t because the robots are coming for us—it’s cultural.As jobs get disrupted and people’s livelihoods are threatened，it’s easy to point fingers at technology as the unavoidable reason，whether you’re an expert or an employer.But what is actually to blame is a society that is willing to let workers be mistreated.It’s a big thing to change，but it’s not set in stone.And that’s the real “robots and jobs” conversation we need to be having. 1.What does the underlined word “slashed” in paragraph 1 mean? A.Created. B.Improved. C.Reduced. D.Removed. √ 词义猜测题。根据第一段中的“But he is also wanted—at a small amount of his normal rate—to ‘rewrite’ the AI-generated text.”可知，技术减少了他的薪水，因此slash的意思是“减少”，和reduce意思相近，故选C。 解析 2.What did Mateescu and Elish find? A.Automated technology was taking away almost all jobs. B.New advanced devices were being integrated in various jobs. C.Humans were still needed to take care of AI-generated problems. D.Humans couldn’t understand the real value in their own jobs. √ 推理判断题。根据第三段中的“For example，automated checkout machines kept employees busy，because they were assisting confused customers，troubleshooting machines，and taking on other tasks to ensure their smooth operation in the store.”可知，Mateescu和Elish发现人类仍然需要处理人工智能产生的问题。故选C。 解析 3.What’s the main cause of the deskilling and devaluing of labor? A.The introduction of robots. B.The nature of jobs. C.The change of workers. D.The attitude to labor. √ 推理判断题。根据最后一段中的“The important thing to understand is that the current deskilling and devaluing of labor isn’t because the robots are coming for us—it’s cultural.”和“But what is actually to blame is a society that is willing to let workers be mistreated.”可知，劳动力低技能化和贬值的主要原因是社会对待劳动的态度。故选D。 解析 4.What’s the best title for the text? A.Work Gets Deskilled by Robots B.Robots Aren’t Coming for Our Jobs C.A Promising Future：Humans and Robots D.A Wanted Conversation：Humans and Robots √ 标题归纳题。通读全文，尤其是第二段末句和第三段第二句可知，本文主要论述的是人工智能对未来工作的影响——它不会夺走我们的工作，而是会改变工作的性质，因此最好的题目是B选项(机器人不会抢走我们的工作)。故选B。 解析 1.release vt.&n.排放；释放；发布 2.complicated adj.复杂的；难懂的 3.counter to与……相反 4.invisible adj.看不见的；无形的→visible adj.看得见的；可见的→visibility n.能见度；可见性 词汇积累 This is not the first time that technology has slashed salaries instead of jobs，and the real problem is not AI. 分析：此句包含句型：That/This/It is the first time that...(that从句用现在完成时)；That/This/It was the first time that...(that从句用过去完成时)。 翻译：技术大幅度削减了工资却没有完全取代人的工作，这不是第一次了，真正的问题并不是人工智能。 句式分析 Ⅵ.完形填空 (2024·湖北荆州高二上期末) I believe joining ASB was one of the best decisions of my eighth-grade year，and being a part of the journalism committee was a wonderful experience. 语篇解读　本文是一篇记叙文。这篇文章主要描述了作者克服了在学校生活中各种活动之间平衡的困难，并对即将到来的高中生活充满期待。 1.A.desire B.intention C.sense D.warning 2.A.class B.community C.group D.band √ After the first meeting，I had a strong 1 that ASB was going to be a thrill(令人兴奋的经历).
