She always has an immediate answer for any question I put to her, and even uses my answers to learn more about my preferences. It used to feel like 50 per cent of my time was spent researching new restaurants. In contrast, my PA only needs a few seconds to find the right place. Every recommendation she gives me is great since she can predict if I will like a particular restaurant. 课后巩固 多维提能 And speaking of hanging out, I'm hoping that self-driving cars are available soon. I've been taking driving lessons for over a year, and still haven't got my licence. Self-driving cars can learn to drive in the same way that we do, and can make judgements based on information. And as they won't be susceptible to human error, they'll certainly be a lot safer. The only thing is that there might be a few machine-learning problems when the first cars hit the market, so perhaps I'd better learn to drive first. Still, I do think that developments in AI will on the whole make doing day-to-day things a lot easier. 课后巩固 多维提能 Pink_haze Machine learning is something we have come to accept as a part of our modern world. I believe most of the value of AI lies in its capacity to analyse and interpret vast amounts of data, which means it can even solve problems that are too challenging for human experts. 课后巩固 多维提能 But while super-intelligent AI could be the biggest leap forward in human history, if it goes wrong or falls into the wrong hands, it could also be the most dangerous. However, AI is not going to go away. We have no choice but to embrace it and regulate it. One thing I think we all agree on, though, is that saying “My AI did it！” won't be any excuse for illegal or immoral behaviour！ 课后巩固 多维提能 √ 1.What's the function of the words of Stephen Hawking？ A．To give the background. B．To put forward the question. C．To introduce the topic. D．To express the purpose. 课后巩固 多维提能 4 2 3 1 √ 2.What does the underlined word “hit” mean in paragraph 3？ A．Accidentally strike. B．Cause harm.

Microrobots can do this well, so they help doctors find patients' health problems earlier and provide treatments that fit each patient. 课后巩固 多维提能 However, the research says most microrobots have a problem, in which they are currently made of a single material system, with their production process focused on a driving module as the main structure. This makes it hard for one microrobot to combine various functions, which are necessary for completing complex jobs. 课后巩固 多维提能 To fix this, researchers from the Technical Institute of Physics and Chemistry of the Chinese Academy of Sciences (CAS) created this hand-shaped microrobot. As CAS explained, when using the robot, researchers first put it in a liquid. When the surrounding pH value changes, the microrobot's “palm” unfolds or folds like flower petals—just like your hand pulls back automatically when touching hot water. Guided by a magnetic field, this microrobot can avoid obstacles and target particles or cells. When the liquid turns acidic (酸性的), its “palm” shuts to hold the target tightly. Then the robot turns and adjusts its direction to take the target to the right place. When the liquid becomes alkaline (碱性的), the “palm” opens again to release the particles or cells. 课后巩固 多维提能 Researchers say this robot may soon be used to control cells, carry drugs for accurate treatment, and even help protect the environment. 【解题导语】　本文是一篇说明文。文章介绍了中国科研团队研发的3D手型微纳机器人。 课后巩固 多维提能 √ 1.What can we learn about the 3D hand-shaped microrobot？ A．It has a wide range of applications in industry. B．It has a diameter equal to that of a human hair. C．It was first reported in a Chinese scientific journal. D．It can perform precise actions like grabbing cells. 解析：细节理解题。根据第一段中的“to achieve precise movements... particles or cells”可知，这款3D手型微纳机器人能够完成抓取、递送和释放细胞等精确动作。 4 5 6 7 8 1 2 3 课后巩固 多维提能 √ 2.Why can't most current microrobots finish complex tasks？ A．They are made of some complex materials. B．They can't work in the liquid environments. C．Their single-material design limits them to a single function. D．Their production process overemphasizes the driving module. 解析：细节理解题。根据第三段内容可知，大部分现有的微纳机器人因单材料设计而功能单一，难以完成复杂任务。 4 5 6 7 8 2 3 1 课后巩固 多维提能 3.What can we infer about the “palm” of the microrobot？ A．It has the same softness as a human hand. B．Its movement is related to the liquid's pH. C．It can only function properly in acidic liquid. D．It requires a magnetic field to open and close fully. 解析：推理判断题。根据第四段中的“When the surrounding pH value changes...when touching hot water.”可知，微纳机器人的“手掌”的张合运动与液体的pH值变化直接相关。 √ 4 5 6 7 8 2 3 1 课后巩固 多维提能 √ 4.Which of the following is the most suitable title for the passage？ A．Differences Between Old and New Microrobots B．The History of Microrobot Research in China C．A New Microrobot for Medical and Environmental Uses　 D．A New Hand-Shaped Microrobot by Chinese Researchers 解析：标题归纳题。通读全文，尤其是根据第一段内容可知，文章围绕中国研究人员研发出3D手型微纳机器人展开。因此，D项最适合作文章标题。 4 5 6 7 8 2 3 1 课后巩固 多维提能 B (2026·龙岩高二期中)How do you beat the summer heat? If you're like most people, you turn the air conditioning on when it's the hottest time of the day.But what if you could use nonpeak (非高峰时间的) electrical hours and store the cold to use the next day? This idea has become a reality for a New York City high-rise that's being cooled by ice. 课后巩固 多维提能 Eleven Madison, a skyscraper in the heart of Manhattan, is using cool, frozen ice overnight to cool the building, reported CBS News.Four stories below ground, an ice battery system freezes water during the night, when electrical use is low, and uses this ice to cool the building during the day.“There's about 500，000 pounds of ice created every night，” said Holly Paeper, president of Trane Technologies, a company that did the installation (装置). 课后巩固 多维提能 Air conditioning uses nearly 20% of energy use in homes and businesses globally.However, on extremely hot days, that number can jump to 70%.Installations like the one in Eleven Madison help to lower that.According to Paeper, the company has installed the technology in about 4，000 sites worldwide. 课后巩固 多维提能 The system in the basement of Eleven Madison uses 100 tanks that are each the size of a parking spot.Because there's a lot of energy consumed in freezing water, a more effective way had to be found.“We take water, and add some other elements in it，” explained Dr.Patrick Shamberger, an associate professor at Texas A&M University.“So we can take control of that temperature basically anywhere we want it, in the zero to 20℃ range.” 课后巩固 多维提能 While ice batteries aren't being used to cool food or to power electrical devices, they're being used to cool buildings.For now, combining ice batteries with other types of energy storage from renewables can help the power grid (电网) to keep up in hot weather as well as lower the cost of electricity.It's a win-win for all. 【解题导语】　本文是一篇说明文。文章介绍了纽约市一栋摩天大楼采用夜间制冰、白天用冰制冷的冰电池系统，既缓解电网压力又降低电费，是创新的降温方案。 课后巩固 多维提能 √ 5.What do we know about the way Eleven Madison cools the building？ A．It uses air conditioning all day long. B．It freezes water during the daytime when electrical use is low. C．It creates large amounts of ice every night. D．It has an ice battery system on the ground floor. 解析：细节理解题。根据第二段中的“Four stories below ground...uses this ice to cool the building during the day.”可知，十一麦迪逊大楼通过夜间制造大量冰块，利用冰电池系统为建筑降温。 4 5 6 7 8 2 3 1 课后巩固 多维提能 √ 6.What does the author want to stress in paragraph 3？ A．The necessity of ice batteries. B．The popularity of the technology. C．The features of the high-rise. D．The significance of air conditioning. 解析：推理判断题。根据第三段中的“Air conditioning uses nearly 20% of energy use...help to lower that.”可推知，作者通过强调空调能耗高的问题，突出冰电池系统的必要性。 4 5 6 7 8 2 3 1 课后巩固 多维提能 √ 7.Why were some elements added in the water？ A．To make the water cleaner. B．To use the energy fully. C．To control the temperature. D．To add space occupation. 解析：细节理解题。根据第四段中的“We take water, and add some other elements...in the zero to 20℃ range.”可知，在水中添加其他元素是为了控制温度。 4 5 6 7 8 2 3 1 课后巩固 多维提能 √ 8.What can be a suitable title for the passage？ A．Process of Ice Battery Production B．Power-hungry Air Conditioning C．Advantages of Storing Electricity D．A Creative System for Cooling 解析：标题归纳题。通读全文，尤其是第一段中的“But what if you could use nonpeak electrical hours...being cooled by ice.”可知，文章围绕冰电池这一创新降温系统展开，介绍其原理、优势和应用。因此D项最适合作为文章标题。 4 5 6 7 8 2 3 1 课后巩固 多维提能 Ⅱ.完形填空 (2026·青岛高二上学期期中)Dashrath Manjhi lived in a poor village in India.There, a 300-foot-high mountain stood between the village and all the basic facilities people always ___________． C．needed 课后巩固 多维提能 Dashrath worked on the other side of the mountain.At noon, his wife Phaguni would bring his ___________ to him.As there was no road, the ___________ took hours over the mountain.One day, Phaguni fell down on the way.She ___________ down several feet, injuring her leg.Hours past noon, she limped (跛行) to her husband.Seeing her tears, Dashrath made a ___________．He wanted to move the ___________ himself.
