英语　选择性必修 第三册 WY Period Ⅰ　Starting out & Understanding ideas Artificial Intelligence： A REAL THREAT 人工智能： 一个真实的威胁？ In the words of Professor Stephen Hawking, artificial intelligence will be “either the best, or the worst thing, ever to happen to humanity”． 用史蒂芬·霍金教授的话来说，人工智能将是“人类有史以来最好的，或者是最坏的事情”。 Technology of Tomorrow Forum wants to hear your thoughts on AI. 明日科技论坛想听听你对人工智能的看法。 Is it our greatest human achievement so far 这是我们人类迄今为止最伟大的成就吗？ Or is it the biggest threat to our existence 还是说它是对我们生存的最大威胁呢？ 词句自测 ①artificial adj. 人造的，人工的 ②artificial__intelligence 人工智能 ③humanity n. 人类 Millenniumbutterfly 千禧蝴蝶 Thanks to AI, I've got my own super smart personal assistant built into my phone. 多亏了人工智能，我的手机里有了我自己的超级智能个人助理。 She always has an immediate answer for any question I put to her, and even uses my answers to learn more about my preferences. 对于我提出的任何问题，她都能立即给出答案，甚至还会用我的答案来了解更多关于我的偏好。 词句自测 ④assistant n. 助手，助理 It used to feel like 50 per cent of my time was spent researching new restaurants. 过去，我感觉自己有50%的时间都花在了研究新餐馆上。 In contrast, my PA only needs a few seconds to find the right place. 相比之下，我的个人助理只需要几秒钟就能找到正确的地方。 Every recommendation she gives me is great since she can predict if I will like a particular restaurant. 她给我的每一个推荐都很好，因为她可以预测我是否会喜欢某一家餐厅。 词句自测 ⑤“主句(Every recommendation she gives me is great)＋原因状语从句(since she can ... restaurant)”。主句结构为“主(Every recommendation)系(is)表(great)”，其中she gives me是定语从句，修饰先行词recommendation。从句结构为“主(she)谓(can predict)＋宾语从句(if I will like a particular restaurant)”。 And speaking of hanging out, I'm hoping that self－driving cars are available soon. 说到出去玩，我希望不久能有自动驾驶汽车。 I've been taking driving lessons for over a year, and still haven't got my licence. 我已经上驾驶课一年多了，但仍然没拿到驾驶证。 Self－driving cars can learn to drive in the same way that we do, and can make judgements based on information. 自动驾驶汽车可以像我们一样学习驾驶，并且可以根据信息做出判断。 And as they won't be susceptible to human error, they'll certainly be a lot safer. 由于它们不会受到人为错误的影响，它们肯定会安全得多。 The only thing is that there might be a few machine－learning problems when the first cars hit the market, so perhaps I'd better learn to drive first. 唯一的问题是，当第一批汽车上市的时候，可能会有一些机器学习的问题，所以也许我最好还是先学会开车。 Still, I do think that developments in AI will on the whole make doing day－to－day things a lot easier. 不过，总体而言，我确实认为，人工智能的发展将使日常工作变得容易得多。 词句自测 ⑥susceptible adj. 易受影响的 Popkid 潮流小孩 The technology you're using and enjoying today is a basic form of AI which can' ... ...
