Given the astonishing potential of AI to transform our lives, we all need to take action to deal with our AI-powered future, and this is where AI by Design: A Plan for Living with Artificial Intelligence comes in. This absorbing new book by Catriona Campbell is a practical roadmap addressing the challenges posed by the forthcoming AI revolution (变革).
In the wrong hands, such a book could prove as complicated to process as the computer code (代码) that powers AI but, thankfully, Campbell has more than two decades’ professional experience translating the heady into the understandable. She writes from the practical angle of a business person rather than as an academic, making for a guide which is highly accessible and informative and which, by the close, will make you feel almost as smart as AI.
As we soon come to learn from AI by Design, AI is already super-smart and will become more capable, moving from the current generation of “narrow-AI” to Artificial General Intelligence. From there, Campbell says, will come Artificial Dominant Intelligence. This is why Campbell has set out to raise awareness of AI and its future now—several decades before these developments are expected to take place. She says it is essential that we keep control of artificial intelligence, or risk being sidelined and perhaps even worse.
Campbell’s point is to wake up those responsible for AI—the technology companies and world leaders—so they are on the same page as all the experts currently developing it. She explains we are at a “tipping point” in history and must act now to prevent an extinction-level event for humanity. We need to consider how we want our future with AI to pan out. Such structured thinking, followed by global regulation, will enable us to achieve greatness rather than our downfall.
AI will affect us all, and if you only read one book on the subject, this is it.
1.What does the phrase “In the wrong hands” in paragraph 2 probably mean

Want to read more books Research shows that reading books provides surprising benefits, including better brain function and a longer life. Since reading is so beneficial, can it be made easier Yes, and the following tips may help.

Ideally, the book you choose should be one you’re interested in. So, if you find a book’s not grabbing you, don’t force yourself to keep going in a literary forced march. That could make you sick of reading. Unless it’s a book you must read for work or school, put it aside and choose a different one. Libraries, bookstores, and various websites are happy to recommend books. 2 .
Fit reading into your schedule
If your schedule is already tight, you may be wondering how you’ll find the time to read. 3 , but some solutions can help. For example, consider loading e-books onto your phone. Besides, if you spend a lot of time driving, consider audiobooks, which can really help pass the time when you’re stuck in traffic. 4 .
Find companions to read with
One of the best ways to stay on track with reading is to join a book group either in person or online. Sometimes it can have a theme, so if you’re particularly interested in science or world history, you can find a group that fits your tastes. 5 . Gather a few friends or colleagues; invite them over for a book discussion.
Reading books is so good for you in so many ways. It’s well worth the effort to keep experimenting until you find the right approach.
A. Choose the right books
B. Select suitable locations
C. You can even create your own
D. There are no easy answers to that question
E. Plus, they’re particularly great when you’re working out
F. Reading both professional and user reviews is also a good trick
G. In comparison, online reading and e-books are more entertaining

文章主要介绍了Catriona Campbell所著的AI by Design: A Plan for Living with Artificial Intelligence一书。该书作为应对AI革命挑战的实用指南,以商业视角阐述AI发展现状与前景,强调控制AI的重要性,呼吁各界协同确保人工智能安全发展,以防潜在危机。
1.C 词句猜测题。第二段主要介绍了《人工智能设计》这本书的作者信息。由画线词后文中的 but 可知,所在句子前后语义转折。but 后是一般现在时描述一种事实,指出这本书的作者 Campbell 拥有二十多年的专业经验,能将枯燥难懂的内容变得很通俗易懂。but 前提到,这本书可能会像计算机代码一样复杂难懂,其中 could 表示一种假设或可能情况,由此可推知,but前应该是假设一个除 Campbell 之外的作者写出这本书的情况。此处的“错误的人”指的是不太称职的人,与作者形成对比,突出这本书作者的专业。
2.B 细节理解题。第二段最后一句提到,《人工智能设计》这本书的作者从商业人士(而非学者)的实用角度出发,使得这本书极易理解、内容丰富。这意味着该书不会涉及过于复杂或技术性的语言,而是旨在为广泛读者群体提供易于理解的、接地气的内容。B 项中的 down-to-earth 同义替换文中的 practical和“highly accessible”。
3.C 推理判断题。第三段最后一句中,Campbell 建议必须保持对人工智能的控制。第四段指出,Campbell 期望科技公司和世界领导人与当前正在开发它的所有专家保持一致,并表示人类处在历史的“转折点”,必须立即采取行动,以防止面临灭绝级别的事件。这表明了她呼吁人们共同努力来控制AI的发展,以避免潜在的灾难。C项中的“keep it under control”同义替换文中的“keep control of artificial intelligence”。
4.A 写作意图题。通读全文可知,第一段介绍了新书《人工智能设计:与人工智能共生的计划》;第二段介绍了本书作者的背景;第三到四段概述了书中的主要论点和观点及其意义;第五段进行总结,再次强烈推荐这本书。由此可知,作者写这篇文章是为了推荐一本有关 AI的书。
