Ⅰ.阅读理解 A There is no doubt that the world will be a very different place in 2045.So what's going to happen then? It's pretty likely that robots and AI technology will change a lot of industries.Also, self­driving and flying cars will come into our daily life, bringing us much convenience. However, scientists have even bigger ideas.In a video series called Forward to the Future, three researchers predicted what they imagined would be reality in 2045. Dr.Justin Sanchez believes we'll be at a point where we can control things simply by using our mind.“Imagine a world where you could just use your thoughts to control your environment，” Justin said.According to him, experts are working on certain technologies that can make this happen.They've made some progress already. The future has more than just that.Many other exciting things could change the building and other objects around us, says Stefanie Tompkins.“We'll be able to build things that are very strong but also lightweight (轻量型的).We don't even know the materials around us，” she predicted. Pam Melroy believes we're going to find that we have a very different relationship with the machines around us.“I think we'll begin to see a time when we're able to control a machine just by pressing a button (按钮) or only saying some simple words，” she said.For example, right now to land a plane safely, a pilot has to go through many steps in the right order.But in 2045, in Pam's words, a pilot may just need to say the words “prepare for landing”．Then the computer knows the steps it needs to take.Or perhaps, with AI, a pilot won't even be necessary. [语篇解读]　本文是一篇说明文。文章预测了2045年世界将大变，机器人、自动驾驶等普及，三位研究者还展望了脑控技术、新型材料及人与机器的全新互动模式等未来景象。 1．What does the underlined word “this” refer to in Paragraph 3? A．Making progress in AI technology. B．Driving flying cars in our daily life. C．Controlling things by using our mind. D．Using robots in different industries. 解析　C　词义猜测题。根据画线词上文“Imagine a world where you could just use your thoughts to control your environment”以及“experts are working on certain technologies that can make”可知，专家们正在研发一些能够实现“通过运用我们的思维来控制事物”这一目标的技术，故this指的是“通过运用我们的思维来控制事物”。故选C。 2．Which of the following would be possible according to Stefanie? A．AI helps pilots to land planes. B．Computers operate all machines. C．Self­driving cars travel around us. D．Houses are strong but lightweight. 解析　D　细节理解题。根据第四段“We'll be able to build things that are very strong but also lightweight (轻量型的).”可知，房屋坚固但又轻便是可能实现的。故选D。 3．Which is the best title for the passage? A．Challenges for AI in the Future B．Experts' Predictions of Life in 2045 C．Famous Scientists in New Technologies D．New Kinds of Building Materials 解析　B　主旨大意题。文章预测2045年世界将大变，机器人、自动驾驶等普及，三位研究者还展望了脑控技术、新型材料及人与机器的全新互动模式等未来景象。由此可知，B选项“专家对2045年生活的预测”最符合文章标题。故选B。 4．In which part of a newspaper can we read this passage? A．Health and Lifestyle. B．Education and Culture. C．Nature and Environment. D．Science and Technology. 解析　D　推理判断题。文章预测2045年世界将大变，机器人、自动驾驶等普及，三位研究者还展望了脑控技术、新型材料及人与机器的全新互动模式等未来景象。由此推知，我们在报纸的“科学与技术”部分能读到这段内容。故选D。 B When Goldie Nejat began developing robots in 2005, she spent much of her time knocking on doors to let people know how her robots worked but few showed interest.“But now, it's different，” says Nejat.“People calling from around the world ask when my robots are going to be ready.” Nejat's robots are designed to meet an increasing need—care­giving for the old.The population of the people over age 80 will be more than 426 million in 2050, about three times larger than that now. Such robots could be especially useful to patients with Alzheimer's disease (阿尔茨海默病).They can help with everyday activities from preparing food to telling the patients to take their medicine on time.They can also play games with patients to keep them active. Some have worried that care­giving robots might reduce human interaction (互动) and cause more humans to lose their jobs.“But the purpose is to support human care, not to take the place of it，” says Brian Scassellati.He has tested robots with different patients, and found that daily interaction with robots can help children with autism spectrum disorder (自闭症谱系障碍) improve social skills. As a field grows, scientists try to understand human­robot relationships (关系) better.Do robots offer advantages because they don't have feelings and don't give opinions? Will patients lose interest? “One thing is clear，” Scassellati says.“Robots can give care to the patients and the need for that will increase in the future.” [语篇解读]　本文是一篇说明文。文章主要介绍了护理机器人的发展、用途、优势以及人们对它的担忧和未来前景。 5．How does the writer start the passage? A．By using sayings. B．By showing some facts. C．By raising a question. D．By providing some suggestions. 解析　B　推理判断题。根据第一段可知，作者通过展示一些事实来开始这篇文章。故选B。 6．What does paragraph 3 mainly talk about? A．The purpose of the robots. B．A test on the robots. C．Serious problems the robots may cause. D．Old people's opinions on the robots. 解析　A　段落大意题。根据第三段“But the purpose is to support human care, not to take the place of it...”可知，第三段主要讲的是机器人的目的。故选A。 7．Which of the following is NOT true according to the passage? A．Scientists are trying to understand human­robot relationships. B．The need for taking care of the old is increasing these years. C．Such robots can help autistic children improve their social skills. D．Many people called to order the robots when they were first made. 解析　D　细节理解题。根据第一段可知，当Goldie Nejat开始研发机器人时，鲜有人表现出兴趣。D选项“当机器人刚制造出来时，许多人打电话来订购机器人。”不正确。故选D。 8．From Scassellati's words, we can infer that Nejat's robots ________． A．will have feelings soon B．will get more popular C．can take the place of humans D．can give their own opinions 解析　B　推理判断题。根据最后一段中“One thing is clear，” Scassellati says.“Robots can give care to the patients and the need for that will increase in the future.”可知，从Scassellati的话中，我们可以推断出Nejat的机器人将会更受欢迎。故选B。 Ⅱ.完形填空 Mark, a genius Swiss, is a professor in the New York Academy of Engineering.Due to his distinct academic performances, he is widely acknowledged as a(n) 1 scientist.
