42. What does the underlined word “ubiquitous” in Paragraph I probably mean? ( )
- A. Enormous in quantity.
- B. Changeable daily.
- C. Stable in quality.
- D. Present everywhere.
答案：D
答案句：Certain forms of AI are indeed becoming ubiquitous. For example, algorithms(算法)carry out huge volumes of trading on our financial markets, self-driving cars are appearing on city streets, and our smartphones are translating from one language into another.
参考译文：某些形式的人工智能确实正变得无处不在。例如，算法在我们的金融市场上执行大量交易，自动驾驶汽车出现在城市街道上，我们的智能手机正在将一种语言翻译成另一种语言。
定位线索：题干“ubiquitous”→答案句首句“ubiquitous”；文中“becoming ubiquitous”对应选项D“Present everywhere”（无处不在）；后文举例“algorithms...self-driving cars...smartphones”体现普遍存在。
解析：题干要求猜测“ubiquitous”的含义。答案句首句直接包含该词，后文用“For example”列举了算法交易、自动驾驶汽车、智能手机翻译等普遍现象，说明AI已广泛存在，因此“Present everywhere”（无处不在）正确。选项A“数量巨大”、B“每日变化”、C“质量稳定”均与上下文无关，属于无中生有。
43. What could AGI do for us, according to its supporters? ( )
- A. Help to tackle problems.
- B. Make brains more active.
- C. Benefit ambitious people.
- D. Set up powerful databases.
答案：A
答案句：AGI could, its advocates say, work for us around the clock, and drawing on all available data, could suggest solutions to many problems.
参考译文：其支持者说，AGI可以全天候为我们工作，并利用所有可用数据，为许多问题提出解决方案。
定位线索：题干“AGI...supporters”→答案句“its advocates say”；文中“suggest solutions to many problems”对应选项A“Help to tackle problems”（帮助解决问题）。
解析：题干问AGI据其支持者能为我们做什么。答案句明确说“could suggest solutions to many problems”，即提出解决方案，与选项A“Help to tackle problems”同义。选项B“使大脑更活跃”、C“使有抱负的人受益”、D“建立强大数据库”均未在原文提及，属于无中生有。
44. As for Irving Good's opinion on ultra-intelligent machines, the author is ____________. ( )
- A. supportive
- B. disapproving
- C. fearful
- D. uncertain
答案：B
答案句：Since the early days of AI, imagination has outpaced what is possible or even probable. In 1965, an imaginative mathematician called Irving Good predicted the eventual creation of an “ultra-intelligent machine … that can far surpass all the intellectual(智力的)activities of any man, however clever.” Good went on to suggest that “the first ultra-intelligent machine” could be “the last invention that man need ever make.”
参考译文：自人工智能早期以来，想象力已超越了可能甚至可行的范围。1965年，一位富有想象力的数学家欧文·古德预言了“超级智能机器”的最终创造，它“能远远超越任何人的所有智力活动，无论其多么聪明”。古德接着提出，“第一台超级智能机器”可能是“人类需要做出的最后一项发明”。
定位线索：题干“Irving Good's opinion”→答案句引用其观点；文中“imagination has outpaced what is possible”和“imaginative mathematician”暗示作者认为其观点不切实际，对应选项B“disapproving”（不赞同）。
解析：题干问作者对欧文·古德观点的态度。答案句先指出“imagination has outpaced what is possible”，即想象力超越了现实可能，再用“imaginative”（富有想象力的）形容古德，暗含其观点过于理想化，不切实际，因此作者是不赞同的（disapproving）。选项A“支持”与原文批判性语气矛盾；C“恐惧”、D“不确定”均无原文依据，属于无中生有。
45. What can be inferred about AGI from the passage? ( )
- A. It may be only a dream.
- B. It will come into being soon.
- C. It will be controlled by humans.
- D. It may be more dangerous than ever.
答案：A
答案句：But all of today's excited discussion about these possibilities presupposes the fact that we will be able to build these systems. And, having spoken to many of the world's foremost AI researchers, I believe there is good reason to doubt that we will see AGI any time soon, if ever:
参考译文：但今天所有关于这些可能性的热烈讨论都预设了我们能够建造这些系统这一事实。而且，在与世界上许多顶尖的人工智能研究人员交谈后，我相信我们有充分的理由怀疑我们是否会在不久的将来看到AGI，甚至永远看不到。
定位线索：题干“inferred about AGI”→答案句取自末段“I believe there is good reason to doubt that we will see AGI any time soon, if ever”；文中“doubt”“any time soon, if ever”对应选项A“may be only a dream”（可能只是梦想）。
解析：题干问从文章能推断出关于AGI的什么信息。答案句明确指出作者怀疑我们是否会在不久的将来看到AGI，甚至永远看不到，这暗示AGI可能不会实现，只是梦想，对应选项A。选项B“will come into being soon”与原文“doubt that we will see AGI any time soon”矛盾；选项C“will be controlled by humans”原文未提及；选项D“may be more dangerous than ever”虽在文中提到风险，但题干问的是推断，且答案句重点在实现可能性，D偏离了答案句的核心。因此A正确。
