As I approached her, Delle turned towards me and became playful, greeting me by splashing me with her beak. Delighted, I reached out to pat her shiny skin. It felt rubbery, which was the main giveaway that the dolphin Delle was a robot. Just as fake (假的) animals are becoming very realistic, it's becoming increasingly less acceptable to use live animals for entertainment purposes.Documentaries like Blackfish (2013) and The Cove (2009) have exposed some of the horrific treatment and suffering of ocean mammals. The resulting public protest has made aquariums (水族馆) controversial and has made them attract less visitors. Arguably, entertaining people with captive (圈养的) animals is vital for animal conservation. Many zoos and aquariums actively try to promote conservation efforts by providing educational experiences and encouraging interest in the natural world. This type of entertainment is useful, because it inspires people to care. At first, this seems like a reason to avoid replacing the animals with technology. However, research in the rapidly developing field of human－robot interaction is showing astonishing results on engagement with robots that can imitate lifelike behaviour. When physically interactive, robots attract a lot of attention. People tend to treat them like they're alive, even though they know perfectly well they're just machines. If we start to replace the animals in our theme parks with machines, will this trend decrease our wonder for the natural world? A bunch of people expressed negative gut reactions (本能反应) after I posted the video of the robot dolphin on social media. And yet, I don't believe that using robot animals will cause us to forget the worth of living creatures. 语篇解读：本文是一篇说明文。文章主要讲述了真实的动物需要保护，现在已经有新的仿真动物机器人出现，它们和人的互动有着良好的反馈。作者支持用仿真动物机器人取代真实动物。 1．Why does the author mention Delle in Paragraph 1?

Steager, an engineer at the University of Pennsylvania (Penn) in Philadelphia and Hyun Koo, an inventor and dental researcher there, found a way to form the nanoparticles into long, skinny bristles (刷毛), a lot like the ones on a toothbrush.But these bristles shape－shift to fit whatever surface they encounter. The tooth－cleaning robot works thanks to two magnets (磁铁)．One goes each side of the teeth.The nanoparticles sit in a liquid between the magnets.When the magnets are turned off, the nanoparticles move randomly in the liquid.As soon as one magnet gets turned on, the nanoparticles gather together near its center.When the researchers turn on the other magnet and turn off the first one, the nanoparticles extend outward in long, skinny bristles.When there's a tooth in the way, these bristles can't stretch out as far as they want.So they push against the tooth's surface.If there's a gap between teeth, they push into the gap. Moving the magnets makes the bristles move against and between teeth. All that motion cleans the teeth. As a bonus, the nanoparticles also have strong power to kill viruses. The new device is just a proof of concept.The researchers still need to turn it into a product that people will want to use.“There's a lot of engineering to get from here to there, but every good idea needs to have a start，” said Steager. 语篇解读：本文是一篇说明文。文章主要讲述了美国宾夕法尼亚大学的研究人员研发出了一款纳米洁牙机器人。 5．What is special about the tooth cleaner? A．It's water－proof. B．It's transformable. C．It looks like a toothbrush. D．It contains skinny bristles. √ 解析：细节理解题。根据第二段中的“But these bristles shape－shift to fit whatever surface they encounter.”可知，尽管这些刷毛和普通牙刷的无异，但这些刷毛可以改变形状来适应它们碰到的任何表面，这是其特殊之处。 6．What is Paragraph 3 mainly about? A．The working principle of the tooth－cleaning robot. B．The magnets' motion. C．The virus－killing process. D．The bristles' formation. 解析：段落大意题。 根据第三段内容尤其是第一句可知，本段主要介绍了洁牙机器人的工作原理。 √ 7．How does Steager feel about the future of the device? A．Uncertain. B．Confident. C．Concerned. D．Surprised. 解析：推理判断题。根据最后一段中 Steager所说的话“but every good idea needs to have a start”可以推断，Steager 对洁牙机器人的前景很有信心。 √ 8．Which of the following would be the best title? A．A Tooth－Cleaner Fighting Bacteria B．A Breakthrough in Medicine C．A Shape－Shifting Robotic Tooth－Cleaner D．A New Concept for a New Start √ 解析：标题归纳题。根据第一段中的“a group of billions of nanoparticles could automatically do all that work for you”以及第二段中的“these bristles shape－shift to fit whatever surface”可知，本文主要介绍了一款可以变形的纳米洁牙机器人，故C项适合作本文的标题。 语篇提能训练 作业（二） Ⅰ.阅读七选五 (2024·大连双基测试)Back in January, I was determined to get fit seriously. 1 But then just as I was close to giving up again, I discovered a brilliant new way to make exercise better: by turning it into a video game. Zwift is essentially a cycling game that you control by riding your real bike, which is equipped with a device called a turbo trainer. This makes it like an exercise bike. As you ride, the trainer sends signals to your computer or tablet to control the character on the screen. 2 For example, as you're cycling up a hill in the game, you can actually feel the different levels of resistance on the bike. After signing up for a ￡ 12/month subscription, you can participate in virtual cycle rides in 3D recreations of real places, like London or fantastical fictional locations invented by the game designers. 3 As you cycle along The Mall towards Buckingham Palace, other real human cyclists appear alongside you, sharing the journey. Though it is obviously only a game, just seeing the character move is surprisingly motivating. __ 4 Go a little faster and you'll be rewarded with a little achievement marker. If you ride harder, you might win a race against another real player and unlock a new item in a regular video game, which can never be matched by a traditional exercise bike. I'm not the only person who has noticed this. 5 Today there are many other companies chasing the same audience, and they all offer their own unique twists on the formula. A．Zwift makes it easy to work out. B．And importantly, you're not alone. C．The rest of the tech industry has, too. D．I played Zwift, a cycling game for training. E．And then the game sends instructions back to the trainer. F．Smartly, the tricks of video games will keep pushing you. G．This would mean hours' stretching and sweating each week. 语篇解读：本文是一篇说明文。文章主要介绍了一款电子游戏，结合安装在自行车上的设备，该游戏可以模拟真实的骑行进行锻炼。 1．解析：选G　根据空前一句“I was determined to get fit seriously”可知，作者决定变得健康；再结合下文可知，作者几乎快放弃了说明运动应该很辛苦，因此空处应承上启下，故G项“这意味着每周数小时的伸展和流汗”符合语境。 2．解析：选E　空前一句讲到，在你骑行时，这个设备会向你的电脑或平板发送信号来控制屏幕上的角色；空后一句讲到，当你在该游戏中骑车上山时，你在自行车上实际可以感受到不同程度的阻力。故E项“然后游戏将操作说明发送给这个设备”承上启下，符合语境。 3．解析：选B　根据空后一句可知，当你沿着皇家英里大道向白金汉宫骑行时，其他骑自行车的真人出现在你身边，与你共享这段旅程。由此可知，B项“重要的是，你并不孤单”衔接下文，符合语境。 4．解析：选F　空处位于句首，为该段主题句；通读该段内容可知，本段介绍了这种电子游戏还有其他的小把戏来推动人锻炼，故F项“更漂亮的是，这种电子游戏的小把戏会持续推动你锻炼”符合语境。 5．解析：选C　根据空前一句可知，作者不是唯一注意到这一点的人；再根据空后一句可知，今天，还有许多其他公司在追逐同样的受众，他们都在这个方法上取得了自己独特的新进展。由此可知，C项“其他的科技公司也注意到了这点”承上启下，符合语境。 Ⅱ.读后续写 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。 (2024·烟台模拟)With the start of new school, freshmen of Hendersonville High School in Nashville were excited to meet new classmates and teachers.Among them, however, 15－year－old Sergio Peralta was feeling very nervous because his right hand had never fully formed since he was born.Going to a new school and being “different” is always scary.Sergio was particularly concerned with what his classmates would think of him. Sergio's parents had trained him to use his left hand from an early age.As he grew up, he was used to not using his right hand.He could write with his left one and do some things with special tricks or techniques.Despite this, in the first days of new school, Sergio always felt like hiding his underdeveloped right hand in his sleeve as if nobody would ever find out if he did so. It didn't take long for someone to learn Sergio's secret.Jeff Wilkins, the teacher of Sergio's engineering class, figured out that Sergio was missing part of his hand and decided to do something for the new student.Jeff had been leading a robotics project in the school and expert in 3D printing technology.Besides, he hoped to take advantage of this hands－on chance to help his robotics students learn more about engineering and how building a robotic hand worked. So in his class, Jeff announced with great enthusiasm, “You're supposed to be engineering, coming up with new ideas and solving issues.Now Sergio needs a new hand, so we'll work together to build Sergio a robotic hand.” His words fueled everyone's curiosity and creativity. For the next four weeks, Jeff and his class including Sergio worked on the project.After some precise measurements and researches, the class put forward a design draft.Jeff made a few adjustments and gave them some practical suggestions.With access to online models and a 3D printer, they eventually created a robotic hand, which was intended to look good and work well, like catching something. 注意：1.续写词数应为150左右； 2．请按如下格式作答。 Then came the final testing day. _____________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ The life－changing gift for Sergio drew huge attention. __________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ ____________________________________________________________ 参考范文： Then came the final testing day.The whole class gathered in the science classroom, watching breathlessly as Jeff carefully loaded their self－made robotic hand onto Sergio's right arm.It fitted quite well! So excited was Sergio that his arm trembled slightly.Having put a baseball on the desk, Jeff signed to Sergio to pick it up.Slowly, Sergio extended his right hand and reached for the ball.Successfully he caught hold of it and everyone present broke into cheers! Holding the ball, Sergio couldn't contain his tears.Never in his life did he expect to catch something with his right hand! The life－changing gift for Sergio drew huge attention.Jeff and his students became an instant hit and various media competed to cover the news.When interviewed about the intention of the project, Jeff said, “I intended Sergio's robotic hand to show our support for him.Meanwhile, I hope to foster students' scientific spirit through this hands－on operation.” His students stated that Jeff challenged them to transform abstract concepts into reality, from which they benefited greatly. Soon voluntary donations poured in, which would go to the school's scientific research and help students develop better. 本课结束 更多精彩内容请登录：www.zghkt.cn $$
