Ⅰ.阅读理解 语篇解读　这是一篇说明文。文章主要介绍了加州大学洛杉矶分校的工程师们设计了一种形似手套的装置，可以帮助使用手语的人直接与非手语者交流。 “Our hope is that this opens up an easy way for people who use sign language to communicate directly with non-signers without needing someone else to translate for them，” said Jun Chen，an assistant professor of bioengineering at the UCLA Samueli School of Engineering and the principal investigator on the research.“In addition，we hope it can help more people learn sign language themselves.” The system includes a pair of gloves with thin，stretchable sensors that run the length of each of the five fingers.These sensors，made from electrically conducting yarns，pick up hand motions and finger placements that stand for individual letters，numbers，words and phrases.The device then turns the finger movements into electrical signals，which are sent to a dollar-coin-sized circuit board worn on the wrist.The board transmits those signals wirelessly to a smartphone that translates them into spoken words at the rate of about one word per second. The researchers also added adhesive(黏合的)sensors to testers’ faces—in between their eyebrows and on one side of their mouths—to capture facial expressions that are a part of American Sign Language. Previous wearable systems that offered translation from American Sign Language were limited by heavy device designs and were uncomfortable to wear，Chen said.The device developed by the UCLA team is made from lightweight and inexpensive but long-lasting，stretchable polymers.The electronic sensors are also very flexible and inexpensive. In testing the device，the researchers worked with four people who are deaf and use American Sign Language.The wearers repeated each hand gesture 15 times.A custom machine-learning algorithm(程序) turned these gestures into the letters，numbers and words they represented.The system recognized 660 signs，including each letter of the alphabet and numbers 0 through 9. 1.What can we learn about the glove-like device from Jun Chen’s words? A.It is mainly intended for sign language learning. B.It can make signers speak in a loud voice. C.It can translate English into other languages. D.It helps signers and non-signers communicate. √ 细节理解题。由文章第二段第一句可知，这种形似手套的装置是用来帮助手语者直接与非手语者交流的。故选D项。 解析 2.What is paragraph 3 mainly about? A.The structure of the device. B.The working process of the device. C.The translating rate of the device. D.The connection between the sensors. √ 段落大意题。由文章第三段中“这些传感器由导电纱线制成，可以捕捉代表单个字母、数字、单词和短语的手势和手指的位置。然后，该设备将手指的动作转化为电子信号，发送到手腕上一块硬币大小的电路板上。电路板将这些信号无线传输到智能手机上，智能手机会以每秒一个单词的速度将信号翻译成语音”可知，本段主要介绍的是该装置的工作过程。故选B项。 解析 3.Why do researchers add adhesive sensors to testers’ faces? A.To reduce the pressure of the main sensors. B.To make the device transmit signals quicker. C.To enrich the sign language users’ facial expressions. D.To make the device understand the sign language better. √ 推理判断题。由文章第四段内容可推测，面部表情也是手语的一部分，研究者将传感器粘到试验者脸上是为了捕捉试验者的面部表情，让该装置更好地理解手语。故选D项。 解析 4.What advantage does the glove-like device have over previous wearable systems? A.It is completely wireless. B.It is light and beautiful to wear. C.It is cheaper and lasts longer. D.It stores and recognizes more signs. √ 细节理解题。由文章倒数第二段中“The device developed by the UCLA team is made from lightweight and inexpensive but long-lasting，stretchable polymers.”可知，这种形似手套的装置相比于以前的可穿戴系统更便宜，更耐用。故选C项。 解析 B Research into social robots has shown that machines that are at the cutting edge of interaction can respond to feelings and emotionally care for the weak, the elderly and children. 语篇解读　本文为一篇说明文。文章介绍了对社交机器人的研究，作者认为用社交机器人来看护将会是一个不可阻挡的有益的趋势。 Robin was designed as a companion robot to provide emotional support for children receiving medical treatment.Robin explains medical procedures to them, plays games and tells stories, and during treatment distracts them to reduce their sense of pain.The robot uses AI to understand other people’s feelings, remembering facial expressions and conversations to build dialogue for follow-up sessions.In trials at the Wigmore Medical(UK) Pediatric Clinic in Yerevan, Armenia, the team found that Robin led to a 34% decrease in stress and an increase in happiness of 26% in the 120 children who interacted with him at least once. Healthcare robots could all benefit from displaying emotional intelligence, both recognizing and responding to human emotions, and to some extent, managing them.The problem with this is the fear that human jobs may be lost as robots become better at handling social situations. Population trends suggest that the demand for robots to work alongside people in care situations will grow over time.By 2050, the number of people aged 65 and over globally will be 1.6 billion(17%), roughly twice the proportion of what it is today.An extra 3.5 million care workers will be needed and that will include emotionally intelligent robots. Today’s simple systems are being trained to meet that demand.This includes a little wheeled robot that can guess how you are feeling from the way you walk, and the robot from the University of Lincoln in the UK—who helps elderly people to stay physically and mentally active. The impact of social robots on our lives to date has been tiny.But new models are being introduced that could make the breakthrough.Human emotions are difficult to define, but as trust in robots increases, breaking down the psychological barrier becomes easier to imagine. 5.What are social robots uniquely capable of? A.Lifting heavy packages upstairs for weak people. B.Comforting mentally ill teens during treatment. C.Cooking delicious dishes for the disabled at home. D.Playing songs for blind people on their request. √ 推理判断题。根据第一段“Research into social robots has shown that machines that are at the cutting edge of interaction can respond to feelings and emotionally care for the weak, the elderly and children.”可知，社交机器人可以对情绪(feelings)作出回应并在情感上(emotionally)关爱弱者、老年人和小孩，这是它的独特之处，故选B项。 解析 6.What is paragraph 2 mainly about? A.Robin’s function to reduce pain. B.Robin’s popularity in hospitals. C.Robin’s practical application. D.Robin’s success in passing tests. √ 段落大意题。根据第二段“Robin was designed as a companion robot to provide emotional support...the team found that Robin led to a 34% decrease in stress and an increase in happiness...”归纳可知，本段介绍了Robin这款机器人的实际用途及其效果。故选C项。 解析 7.How is paragraph 4 developed? A.By concluding viewpoints. B.By analyzing causes. C.By making comparison. D.By giving definition. √ 写作手法题。根据第四段“Population trends suggest that the demand for robots...intelligent robots.”可知，本段的中心句为第一句：人口趋势表明机器人与护理人员一起工作的需求将会逐步增长。接着阐述了原因：未来老龄化的加剧将导致护理人员和社交机器人需求的增加。因此，第四段是通过分析原因展开的。故选B项。 解析 8.What does the author think of human job replacement by robots? A.It is already happening throughout UK. B.It’s an unstoppable and beneficial trend. C.Robots can only meet basic human needs. D.Humans need to work hard to secure jobs. √ 推理判断题。根据第四段中的“Population trends suggest that the demand for robots to work alongside people in care situations will grow over time.”可知，随着社会发展，机器人在护理工作中的需求会持续增长；最后一段中的“But new models are being introduced that could make the breakthrough...becomes easier to imagine.”也强调这一趋势的可能性，可推测作者认为机器代替人类工作的趋势无可阻挡，且对人类有益，故选B项。 解析 “Ladies and gentlemen，the time train has arrived at the terminal！” It felt like I had woken up from a dream， 1 soon discovered I had come to 2035. 1.A.while B.so C.if D.but Ⅱ.完形填空 语篇解读　本文是一篇记叙文，讲述的是作者乘坐时光机体验2035年的交通和饮食的梦境。 √ 结合语意，“感觉自己从梦中醒来”和“发现自己在2035年”之间是转折关系。故选D项。 解析 Suddenly，I heard a strange voice calling my name.I turned around，only to find a robot 2 to me enthusiastically.“I’ll show you around the city in 2035！” I nodded immediately， 3 what the city would be like. 2.A.singing B.waving C.screaming D.flying 3.A.getting B.knowing C.wondering D.wandering √ √ 2.结合语意，机器人第一次见到作者时，应该会挥手打招呼。故选B项。 3.结合语意，作者第一次来到2035年，因此想要知道现在的城市究竟什么样。故选C项。 解析 Once I walked out of the train station，many crossed air lanes came into view.The robot，seeing how 4 I was，explained the new traffic system to me. 4.A.astonished B.scared C.bored D.moved √ astonished吃惊的；scared害怕的；bored无聊的；moved感动的。上文提到作者一走出火车站就看到了横贯的航空线，可知作者会感到非常吃惊。故选A项。 解析 The system was put into place by many famous engineers using highly 5 technology.In fact，it eliminated(消除) the issue of traffic jams entirely. 5.A.standard B.useless C.unusual D.advanced √ standard标准的；useless无用的；unusual不寻常的；advanced先进的。下文“In fact，it eliminated(消除) the issue of traffic jams entirely.”提到这个系统完全解决了交通堵塞这一问题，由此可知它应用了高度先进的技术。故选D项。 解析 Next we made our way to a restaurant nearby.Just as I 6 that there was no menu，a waiter began to scan my body with a special 7 ，which gave me a big fright，so I 8 out of my seat immediately. 6.A.told B.realized C.heard D.reminded 7.A.instrument B.button C.engine D.accelerator 8.A.took B.left C.jumped D.danced √ √ √ 6.tell告诉；realize意识到，发现；hear听说；remind提醒。结合语意，此处是指作者进入餐厅之后意识到餐厅内没有菜单。故选B项。 7.instrument仪器，工具；button按钮；engine引擎；accelerator加速器。下文“The robot explained it was just a machine...”提到机器人向作者解释那只是个机器，由此判断，服务员应该是拿着机器扫描了作者的身体。故选A项。 8.上文“which gave me a big fright”提到作者被服务员拿着机器扫描身体这件事吓着了，所以作者应该是吓得从座位上跳起来。故选C项。 解析 The robot explained it was just a machine that was able to figure out what our body needed and chose the recipe that 9 us most. 9.A.attracted B.suited C.provided D.offered √ attract吸引；suit适合；provide提供；offer提供。由“a machine that was able to figure out what our body needed”可知这种机器可以弄清楚人体所需的营养，因此可以向人们提供最适合他们的食谱。故选B项。 解析 The waiter then introduced me to the electronic screen that allowed me to choose the environment according to my 10 .I pressed the “beach” button on the screen and 11 I felt a sea breeze.I couldn’t help but 12 at how rapidly technology had advanced. 10.A.temperature B.taste C.gene D.place 11.A.suddenly B.sadly C.absolutely D.casually 12.A.aim B.guess C.sigh D.stare √ √ √ 10.temperature温度；taste品味；gene基因；place地方。作者选择了“海滩”的环境，说明这是作者自己的喜好，由此判断可以根据自己的品位选择就餐环境。故选B项。 11.suddenly突然地；sadly悲伤地；absolutely绝对地；casually随意地。由“I felt a sea breeze”可知，作者按下按钮后感受到了环境的变化，这对还坐在餐厅的作者来讲非常突然。故选A项。 12.aim瞄准；guess猜测；sigh感叹；stare凝视。结合语意，作者来到2035年后先看到了发达的交通系统，接着又看到了能够更改就餐环境的餐厅，作者对此非常震惊，因此作者不由得发出感叹。故选C项。 解析 We 13 returned to the train station.Just as I 14 the train，I heard a familiar voice calling my name.I opened my eyes to see my mom standing over me.What a(n) 15 dream! 13.A.immediately B.hardly C.occasionally D.eventually 14.A.put off B.brought in C.got on D.looked into 15.A.terrible B.practical C.awful D.fantastic √ √ √ 13.immediately立即；hardly几乎不；occasionally偶尔；eventually最后。下文“Just as I the train”提到作者正要上车，由此判断作者在2035年的参观之旅已经结束了，所以最后是要坐上火车离开了。故选D项。 14.put off推迟；bring in引进；get on上车；look into调查。结合语意，作者来到火车站是准备坐车的。故选C项。 15.terrible可怕的；practical实际的；awful糟糕的；fantastic奇妙的。作者乘坐时光机去2035年参观了先进的交通系统和能够改变用餐环境的餐厅等，这对于作者而言是一个非常奇妙的体验。故选D项。 解析 返 回 本课结束 $
