Just_as_the_old_saying_goes,_“Every_coin_has_two_sides.”_The_same_is_true_of_artificial_intelligence._On_the_one_hand,_AI_is_our_greatest_human_achievement;_on_the_other_hand,_it_is_the_biggest_threat_to_our_existence_as_well.We_should_make_use_of_it_in_our_daily_life_properly. |阅|读|技|能|提|升| 本文是一篇网络论坛专题讨论，属于新媒体语篇。文章中三位发帖人就“迄今为止，人工智能是人类最伟大的成就还是最大的威胁”发表了不同的看法。阅读的关键是厘清每个人的观点，如：Millenniumbutterfly认为人工智能的发展会使日常生活变得更加便利；而在Popkid看来，能够独立思考的高级人工智能虽能够帮助人类解决许多难题，但也可能对人类的生存构成威胁；Pink_haze则认为我们不应该阻止人工智能技术的发展，而是应该在发展的同时去规范它。 (一)赏用词之妙 1．It used to feel like 50 per cent of my time was spent researching new restaurants. In contrast, my PA only needs a few seconds to find the right place. 赏析：本句中运用in contrast使前后产生鲜明的对比效果，凸显人工智能的优点和Millenniumbutterfly对人工智能的推崇。 2．After all, why would an independent form of AI need to consider the opinions and desires of humans? 赏析：句中用After all “毕竟”引出下文，表达了Popkid对于人工智能可能带来的风险持担忧的态度。 [提能训练|完成句子] ①Most colleagues prefer to take notes with electronic devices, but_in_contrast,_I_still_like_writing_down_key_points_in_a_notebook. 大多数同事更喜欢用电子设备记笔记，但相比之下，我仍然喜欢在笔记本上写下要点。 ②It's not surprising you're tired. After_all,_you_were_up_until_twelve_last_night. 你感到疲惫是很正常的。毕竟，你昨晚十二点才睡。 (二)赏句式之高 1．Still, I do think that developments in AI will on the whole make doing day-to-day things a lot easier. 赏析：本句使用助动词do对谓语think进行强调，突出了Millenniumbutterfly对人工智能的发展抱有的信心。 2．Even if that doesn't happen, there are other risks. 赏析：本句中用Even if 引导让步状语从句表达Popkid的观点，充分表明了他对人工智能的顾虑。 [提能训练|完成句子] ①Whatever you do, do_devote_yourself_to_it and finally you will succeed. 无论你做什么，务必全力以赴，这样才能取得最终的成功。 ②She still decided to try the experiment again, even_if_she_had_failed_many_times_before. 即使之前失败了很多次，她还是决定再尝试一次这个实验。 (三)赏衔接之顺 But while super-intelligent AI could be the biggest leap forward in human history, if it goes wrong or falls into the wrong hands, it could also be the most dangerous. 赏析：此处先是运用衔接词but与上文形成转折关系，然后又使用了衔接词while引导让步状语从句，接着用if引导的条件状语从句补充条件，陈述了超智能AI的问题：虽然超智能AI可能是人类有史以来的最大飞跃，但如果出错或者落入坏人手中，它同时可能是最危险的。衔接词的使用让句与句之间过渡自然顺畅，逻辑清晰合理。 [提能训练|完成句子] We all know that we have to stay at home if_it_rains_tomorrow,_as_it_is_impossible_to have a picnic in the rain, so_we_will_have_to_give_up the plan. 我们都知道，如果明天下雨，我们必须待在家里，因为不可能在雨中野餐，所以我们不得不放弃这个计划。 想象一下，某天早上你醒来，可以选择继续躺在床上，按下一个按钮，就能召唤一台机器人为你处理所有的工作，那该有多酷啊！这听起来可能像是空中楼阁，但鉴于人工智能(AI)目前的发展速度，这样的梦想在将来也许真的可以实现。阅读下面文章，了解人工智能的发展趋势以及这一发展所带来的利弊。 Artificial intelligence: friendly or frightening? Imagine waking up one morning with the option of staying in bed and pressing a button to send a robot to do all the work for you. How cool that would be! It may seem like building castles in the air, but given the rate at which artificial intelligence, or AI, is being developed, in the future such dreams may actually come true. At the basic level, artificial intelligence is a branch of computer science that aims to create intelligent machines. One of the essential aims of AI is learning from experience, adjusting to new inputs and performing tasks like humans. To achieve this aim, many approaches to creating true AI have been put forward, including “deep learning”， which enables a machine to improve its own performance by learning from the results of its previous actions. Deep-learning AI has the capacity to analyse massive amounts of data through multiple layers, imitating the complex networks of the human brain. The dream of AI has been around for centuries, and the development of computers since the 1940s has finally made it a reality. Years before the term “artificial intelligence” was the theory had been explored by Alan Turing, one of the pioneers in the ② field of computer science. However, for a long time, AI technology developed very slowly.A major breakthrough in AI came in 1997, when Deep Blue, a chess-playing computer, beat the world chess champion Garry Kasparov.Then in 2017, a computer program named AlphaGo defeated Ke Jie, arguably the best human Go player, which demonstrated a significant advance in deep-learning AI systems. Nowadays, AI is already being applied in many fields: finance, health care, machine translation and art, to name but a few. From autonomous vehicles to domestic robots, from recommendation systems to computers writing novels, AI has an unlimited number of applications.Ordinary people are now using AI to get instant translations of text in foreign languages, and machines can recognize fingerprints and even faces. In short, this technology is transforming the way we live.It is clear that we are at a turning point in history.With machines like AlphaGo now capable of thinking and learning from their mistakes, we are getting closer to the dividing line between humans and machines.The question is, where will all this lead? While AI enthusiasts promise us a bright future where intelligent robots will be working to our advantage, these undoubted benefits also bring concerns and fears. Could machines really develop human-like intelligence? And what would happen if they did? Would thinking machines work alongside humans or threaten the existence of humans? How would they be punished if they committed crimes or even murdered humans? As we become more and more dependent on computers, some scientists are urging us to think about the dangers posed by the advances in AI. Stephen Hawking, for example, warned, “The development of full artificial intelligence could spell the end of the human race.” Apparently, such warnings demand our attention. We need to make sure that we will not fall victim to AI. We may still think it would be fantastic to relax all day and allow autonomous machines to do all the work for us — but perhaps we should not be too greedy and rather be careful what we wish for!
