B.Indifferent.C.Favourable. D.Disapproving.( )2.What happened to the googly eyes Tina Sorg put on the robot A.They were banned by her supermarket.B.They were well-received by her bosses.C.They went unnoticed by her colleagues.D.They were hit by some customers.( )3.Why is the famous consulting firm mentioned A.To point out the exact amount of labour to be done by robots.B.To celebrate the prospect of robots replacing human workers.C.To emphasise the risk of job loss due to technological advances.D.To stress the power of automation technology in public settings.语篇导读:本文是说明文。文章主要讲述了Tina Sorg为了让机器人看起来更像人类,给机器人增添了一双塑料眼睛,这一举动也给了设计者启示。设计者认为机器人应有足够的人类特质,以带给客户更好的体验。但机器人的普及也引发了大家针对机器人是否会导致人类失业这一问题的讨论。答案及剖析:1.D 推理判断题。根据第一段的最后一句可推测,Sorg对目前的机器人不满意,觉得它需要增添个性。所以D项符合题意。故选D。2.B 细节理解题。根据第三段内容可知,这双眼睛很受食品杂货公司经理们的欢迎。现在该公司遍布美国的近500个机器人都安上了眼睛。由此可知,杂货公司的经理们都很喜欢机器人新添加的眼睛。故选B。3.C 推理判断题。根据第五段内容可知,机器人进入食品杂货店等公共场所,加重了人们对人类将被挤出工作岗位的担忧。but后的内容为强调部分,所以后文提及这家咨询公司是为了进一步强调机器人的出现可能会增加人类失业的风险。故选C。BWhen we long live together,we quickly learn to foresee the near-term behaviours of our co-workers or family members.Our ability to predict the actions of others makes it easier to successfully live and work together.In contrast,even the most intelligent and advanced robots have remained inept at this sort of communication.This may be about to change.The study,conducted by Mechanical Engineering Professor Hod Lipson,is part of a broader effort to provide robots with the ability to understand and predict what others want.The researchers first built a subject robot and placed it in a playpen.They programmed the robot to seek and move towards any green circle it could see.But there was a hidden difficulty.Sometimes the robot could see a green circle in its camera and move directly towards it.But other times,the green circle would be blocked by a tall red cardboard box,in which case the robot would move towards a different green circle,or not at all.After “researching” its partner on screen long,the new robot was eventually able to get its partner’s goal and path 98 out of 100 times,across varying situations.When starting the experiment,the researchers expected the robot might learn to make predictions about the subject robot’s near-term actions.What the researchers didn’t expect,however,was how accurately it could foresee the moves with only a few seconds of video.“Our initial results are very exciting,showing how robots can see the world from another robot’s view,” says Lipson.“The understanding ability of the new robot is perhaps a primitive form of sensing others’ feelings,which we all can do.”Meanwhile,he acknowledges there’re many moral questions.The technology will make robots more adaptable and useful and no longer passive instruction-following machines,but when robots can predict how humans think,they may also learn to control or influence those thoughts.( )4.What does “inept” underlined in the first paragraph mean A.Cautious. B.Smart.C.Active. D.Poor.( )5.What is the experiment designed to find A.How a robot moves toward the targeted object.B.Whether a robot can predict other robots’ goals.C.Whether robots can work together like humans.D.How precisely a robot foresees its partner’s moves.( )6.How does the robot gain the understanding ability A.By communication.B.By following its camera.C.By visual observation.D.By experiencing various tests.( )7.What does Lipson think of the new robot A.It bears human characteristics.B.It has some kind of moral values.C.It might replace human beings.D.It is an instruction-following machine.语篇导读:本文是说明文。文章主要讲述了当人类长时间生活在一起时,他们很快就能预测身边人的行动;现下有一种新型的机器人学会了这一技能。答案及剖析:4.D 词义猜测题。画线词前提到人在一起生活的时间久了,就能知晓对方下一步的动作和意图。结合上文的“In contrast”及下文的“This may be about to change.”和有关机器人的新能力的研究可知,画线词所在句与前面的内容为对比关系。故选D。5.B 细节理解题。根据第二段第一句及第三段第二句可知,实验的目的是要看看机器人是否能够预测其他机器人的行动。故选B。6.C 细节理解题。根据第三段第一句可知,机器人通过视觉观察获得了理解和预测其他机器人的行动的能力。故选C。7.A 推理判断题。根据倒数第二段最后一句可知,在Lipson看来,这种新型的机器人的理解能力可能是人类感知他人感受的一种原始形式。故选A。CScience fiction writers create imaginary worlds.The way things work in your imaginary worlds will be based on actual science.So it’s important for you to be familiar with the scientific principles and inventions that are related to your creation.For example,if you’re writing about humans living on a planet with zero gravity,then you need to know the effects of zero gravity on the human body.Then you have to figure out the exact rules of your imaginary worlds.And you have to follow them.If humans are able to breathe underwater in Chapter 1,your characters can’t drown in a swimming pool in Chapter 3.The issue here is maintaining your readers’ trust.That means readers are willing to pretend along with you.If you start out with an ordinary detective novel and then throw in someone breathing underwater in the 6th chapter,you will pull the readers out of their imagination.The same thing happens if you change the rules halfway.Part of your preparation work for the novel is to map out its world in great detail.You should decide the following issues:the history of the world,the geography,what possibilities it offers,how everything works in this new reality,and how all of these factors affect the way your characters think,feel,and react to things.You don’t have to tell your readers all the rules in the first chapter.But you have to let readers know enough to understand what’s going on.This also allows you to work out logical problems and contradictions before you start writing.When you are writing,remember to make it feel real.You are inviting readers to visit a new world.They will want to be able to see,hear,feel,smell,and even taste what it’s like.Whether your novel is about a world without disease or an undiscovered planet,help your readers feel like they’re actually there.( )8.What’s the relationship between actual science and science fiction A.Science fiction promotes the development of actual science.B.Science fiction often reflects the development of actual science.C.Actual science provides basic principles for science fiction.D.Actual science limits the imagination described in science fiction.( )9.What does the third paragraph focus on A.Part of the preparation work for science fiction writing.B.The different types of novels.C.The detail in the first chapter of science fiction.D.The reality of science fiction.( )10.Which of the following statements is TRUE A.It is necessary to do some scientific experiments before writing science fiction.B.Readers of science fiction actually pretend the writer’s rules are true.C.The target readers of the passage are young scientists.D.It is great to leave some contradictions in your science fiction.( )11.What’s the best title of the passage A.How to Do Scientific ResearchB.How to Write Science FictionC.What to Expect from Science FictionD.How to Raise Interest in Science语篇导读:本文是说明文。科学是科幻小说的基本原理,文章提出了写科幻小说时要注意的事项。答案及剖析:8.C 细节理解题。根据第一段的前两句可知,科学是科幻小说的基本原理。故选C。9.A 段落大意题。根据第三段内容可知,第三段的主旨是科幻小说写作的部分准备工作。故选A。10.B 细节理解题。根据第二段内容可知,科幻小说的读者实际上会假设作者小说世界里的规则是真实的。故选B。11.B 标题归纳题。通读全文可知,文章主要介绍了如何写科幻小说,故B项适合用作文章的标题。故选B。Ⅱ.七选五Whenever humans consider the future of artificial intelligence (AI),they have one big question in mind:Will robots take my job 1. ,new ones that involve working specifically with AI will arise.The biggest change may be in what we get from work.Many jobs will become more rewarding as people perform their work alongside AI,solving problems in new and exciting ways.AI has already changed almost every industry,but the future of AI promises to revolutionise even more businesses. 2. With AI,doctors will be able to better diagnose illnesses.This will make early life-saving treatment more likely.They might use AI to create new ways to treat illnesses like dementia and cancer.They could use it to predict future illnesses,combining a patient’s health history and genetic data to create a preventative care plan.Service IndustryIn the future,robots and machines run by AI could replace customer service representatives and cashiers.We can also have AI-equipped robot cooks.3. . Law EnforcementSome day soon,intelligent robots could even replace police officers to catch potential criminals.4. .As for online security,AI is already in development to intelligently protect consumers online.The AI will be able to detect changes in spending and credit activity and then automatically contact the police. Transportation5. .In the future,cars will be able to drive themselves (some already do).We may also see automated trains and airplanes. MarketingAI already targets you with customised ads on social media sites,but soon it may even be able to create the ads you see or articles you read.A.Health CareB.Find Your WayC.Say goodbye to taxis and driversD.While it’s true that some jobs will disappearE.Robots are already used at some fast-food restaurantsF.AI-run robots are already used as security officers in some businessesG.There are already articles that are almost as good as what a human creates语篇导读:本文是说明文。文章主要介绍了人工智能已经或即将被应用的领域。答案及剖析:1.D 根据空前的“Will robots take my job ”和空后的“new ones that involve working specifically with AI will arise”可知,上文提出问题,下文指出会有新的工作出现。由此可推知,空处应对前文的问题进行回答,并指出人工智能会导致一些工作消失。D项承上启下,符合语境。故选D。2.A 空处概括本段内容,为本段小标题,且应与下文小标题的句式保持一致,即应是名词短语。根据本段描述“With AI,doctors will be able to better diagnose illnesses.”可知,本段主要介绍医疗保健方面的内容。A项概括本段内容。故选A。3.E 根据空前一句可知,空处应承接上文,继续陈述人工智能在餐饮或服务行业的应用。E项承接上文。故选E。4.F 根据空前一句“Some day soon,intelligent robots...potential criminals.”可知,空处应进一步说明智能机器人在安全领域的使用。F项承接上文,符合题意。故选F。5.C 根据后文可知,空处应说明未来人工智能给运输行业带来的变化。C项符合题意,且符合本段主旨。故选C。Ⅲ.语法填空The home of the future won’t be 1.
