In Blade Runner,Harrison Ford hunts robots in a chaotic(混乱的)Los Angel- es. Planet of the Apes shows a hopeless future for humankind. 8 选择性必修第三册 There's a word to describe the kind of future world which often appears in science fiction:dystopia.It means an imagined place where things are unpleas- ant or bad.The opposite is utopia.But does tomorrow's world have to be so dis- appointing? No.A new project wants to use the power of science fiction to inspire people to create a better future.Project Hiero- glyph brings together writers,scientists, engineers and artists to create optimistic stories about things which really could happen in the next 50 years. It's just a matter of making an ef- fort.Experts say it's easier to create a dystopia than write a feel-good story. There's more conflict in a world full of problems,and stories are interesting when there are a lot of problems to solve. No challenge,no story! But the project produced a book with some promising plots.One of them is about environmentalists who fight to stop entrepreneurs(创业者)from building the first hotel in Antarctica.Well,there's conflict there and it seems reasonable,so it could be a good story. But will these stories actually change anything or just keep us entertained?Ed Finn,the book's editor,thinks the for- mer.He says:"A good science-fiction story can be very powerful.It can inspire hundreds,thousands,millions of people to do something that they want to do. The influence of science fiction can already be seen in modern research,says Professor Braden Allenby.He asks: Unit 4 A glimpse of the future "Why are people working on,for exam- ple,invisibility cloaks(斗篷)？Well,it's Harry Potter,right?” Time will tell how far we can go. Let's dream big and think outside the box.Who knows the wonderful things we can come up with? l.The underlined word“utopia”in Para graph 2 most probably means" A.a real world where people can do an- ything they like B.an imagined place where things are unpleasant or bad C.an imaginary perfect world where everyone is happy D.a wild and terrible place where no one can live happily 2.Experts say it's easier to create a dys- topia than a feel-good story because A.a dystopia needs less imagination B.a feel-good story is more interesting C.there is no conflict in a feel-good story D.there are more problems to solve in a dystopia 3.Professor Braden Allenby takes"invisibility cloaks"as an example A.to cause readers'attention B.to amuse science fiction readers C.to introduce a science fiction story D.to show the influence of science fic- tion 4.What is the best title for the passage? A.What is science fiction? B.Can science fiction help us? C.What will man do in the future? D.Shall we live a better life in the fu- ture? .8 课时作业乡 Ⅱ.阅读七选五 There have been a lot of comments 空 recently surrounding 5G,the next gener- ation of wireless technology. 1 ?纠错空间 How might it change our lives? 5G stands for fifth generation, meaning the next step in the progression (进步；进展)of technology to replace the current(现在的)4 G system.Earlier“G” systems were designed to improve mobile communication operations.Each new technology brought major improvements in speed and greatly increased network t4t。4t44444 capacity(容量).2.It is expec- ted to permit more users to do more things at a faster rate. However,technology experts say there is a major way that 5G is different from the earlier systems.3 .It will affect many more devices and indus- 方法总结 tries than other'“G”versions(版本). 5 G will help fuel future“smart cities'” by connecting sensor networks.5G is al- so expected to connect self-driving cars and support new technologies involving virtual reality(虚拟现实).Higher5G speeds could also permit doctors to com- monly perform remote medical opera- tions.Factories and businesses could use 5G technology to increase automation and improve the collection of information. 4.The increased data flow .................. across 5G networks would give Internet attackers a lot more possibilities to steal and misuse data.In addition,the wider use of a 5G wireless network means any breakdown of the system would have more widespread and severe results.Such difficulties could affect public safety. 5 or a network breakdown could cause self-driving vehicles to crash.

But a team of scientists at Harvard University in the US has managed to build an entirely soft robot -one that draws inspiration from an octopus(章鱼).”（传统上，机 器人很硬，由金属和其他刚性材料制成。但美国哈佛大 学的一个科学家团队已经成功制造出了一个完全柔软 的机器人，它的灵感来自于章鱼)可知，“章鱼机器人”的 特别之处在于它很柔软。故选C。] 2.B[细节理解题。根据第三段“And they aren't espe- cially safe around humans,because they're made out of hard and heavy parts that could be potentially dangerous to their users.”(而且它们在人类身边并不特别安全，因 为它们是由坚硬而沉重的部件制成的，可能对使用者有 潜在的危险)可知，传统机器人的缺，点是它们不能一直 表现得很好。故选B。] 3.D[细节理解题。根据倒数第二段“But creating a com pletely soft robot remains a challenge.Even if engineers build a silicone body,it's still a grand challenge to construct flexible versions of essential parts,such as a source of power,”(但是创造一个完全柔软的机器人仍 然是一个挑战。即使工程师们制造出了一个硅胶机身， 但要制造出如电源等关键部件的柔性版本仍然是一个 巨大的挑战)可知，最大的挑战之一是建造Octobot机器 人的柔性电源。故选D。] 4.B[推理判断题。根据最后一段“‘Although soft robot- ics is still in its early stage,it holds great promise for several applications,such as search-rescue operations and exploration,'Barbara Mazzolai and Virgilio Mattoli of the Italian Institute of Technology Center for Micro- BioRobotics,wrote in a comment.'Soft robots might al- so open up new approaches to improving wellness and quality of life..,”(意大利微型生物机器人技术中心的 Barbara Mazzolai和Virgilio Mattoli在评论中写道：“尽 管软机器人技术仍处于早期阶段，但它在搜救行动和探 索等方面有着巨大的应用前景。”“软机器人还可能为改 善健康和生活质量开辟新途径。”)可推知，软体机器人 可能应用于救援等方面。故选B。] B.[语篇解读]本文是一篇说明文。蚂蚁是一种强大的 生物，有高效的求生技能。科学家对巴西的火蚂蚁进行了 研究，发现它们可以结成筏子在洪水里自救，并研究了它 们的自救原理。 ·14 选择性必修第三册 5.A[细节理解题。根据第三段后两句“To save them- selves,the insects connect their legs together and create floating rafts.Some ant rafts can be up to 20 centimeters wide.”可知，作者列举巴西的火蚂蚁是为了告诉我们火 蚂蚁在洪水里会结成筏子自救。故A项正确。] 6.B[推理判断题。根据第四段最后一句“If you have 100 ants,which means 600 legs,99 percent of those legs will be connected to a neighbor.So they're very,very good at keeping this network.”解释了蚂蚁可以把自己 的腿连接在一起形成一个网。这是蚂蚁在洪水里自救 的方法，说明它们了解这样的方法。故B项正确。] 7.B[细节理解题。根据第五段最后两句“The pictures showed that larger ants serve in central positions to which smaller ants hold.The larger ants create pockets of air that keep the insects afloat.”可知在蚂蚁组成的网 里，最大的蚂蚁们在网的最中间，形成一个气泡产生浮 力，让所有的蚂蚁都能漂浮起来。故B项正确。] 8.C[推理判断题。根据文章倒数第二段“Scientists say small robots or materials that can change shape could be programmed in a similar way,working towards a shared g0al.”可知，蚂蚁的行为给科学家启示，可以用蚂蚁自救 类似的方法把一些微型机器人或其他一些玫变形状的 材料组合在一起，一起去完成一个共同的目标。故C项 正确。] Ⅱ.[语篇解读]本文是一篇说明文。文章讲述的是：园 艺在离地球380公里的高空。宇航员必须经过身体、心理 和技术的训练。他们还接受了如何照料植物的培训。这 些“宇航员园丁”与植物分享他们的工作和生活空间。 1.D[下文提示“正因为如此，把长途旅行所需要的东西 都送出去，只用一次就扔掉是不现实的。”承接下文，D项 The cost of taking anything into space is about $22,000 per kilogram,(将任何物体送入太空的成本约为每公斤 22,000美元。)切题。下文中的this指代该项中的The cost,故选D。] 2.F[上文提示“他们可以提供更多新鲜的东西。”再根据 下文提示“此外，植物可以帮助改善空气质量，因为它们 可以产生氧气。”承接上下文，F项Astronauts will wel- come the addition of fruits and vegetables to their diet of dry foods.(宇航员将欢迎在他们的千粮中加入水果和蔬 莱。)切题。故选F。] 3.B[下文提示“由于太空中缺乏重力，植物产生的氧气 停留在植物周围。”承接下文，B项However,there are challenges with growing plants in space.(然而，在太空种 植植物也面临着挑战。)切题。故选B。] 4.E[上文提示“没有重力，根就不‘知道’该往下长，叶子 就不‘知道’该往上长，水也不容易从根往上注入到叶子 上。”再根据下文提示“此外，土壤太重，不能送到太空， 特殊的液体凝胶被用来帮助植物生长。”承接上下文，E Specialized containers are being developed to help the plants grow correctly.(目前正在开发专门的容器来帮助 植物正确生长。)切题。故选E。] 5.C[上文提示“他们试图使植物生长得更快，在空中以 更少的水和光生长，他们正在寻找方法使植物更能抵抗 疾病。”承接上文，C项Such methods may result in im- provements back here on Earth.(这些方法可能会改善地 球。)切题。该项中的methods与上文中的ways相吻合。 故选C。] 8
