In just 100 years, the world has changed completely. Amazing discoveries were made in medicine, communications and transport, not to mention our knowledge of the world and space. 课后巩固 多维提能 Although it is impossible to choose the most important discovery, it is possible to single out a few pioneers of the 20th century. Here are some of them. One of the 20th century's premier scientists was Albert Einstein. In the summer of 1905, this outspoken young man was rocking his one-year-old baby when he was suddenly inspired. Subsequently, “E＝mc2” was born. It showed how a small piece of mass could produce an unbelievable amount of energy. 课后巩固 多维提能 In 1928, another important finding was made by biologist Alexander Fleming. Before he went on holiday, Fleming left a dish of bacteria in his laboratory.When he came back, he noticed something strange. He double-checked and saw a blue mould in the dish around which the bacteria had been destroyed. This blue mould was in fact the natural form of penicillin, which Fleming perceived could be used to kill bacteria. A few years later, penicillin was being mass-produced and helping to save the lives of millions. 课后巩固 多维提能 During World War Ⅱ，when Fleming's discovery was first helping to cure people, the US Navy was looking for ways of improving the accuracy of their missiles. The navy turned to Eckert, an engineer, and Mauchly, a physicist, to deal with the problem and produce a machine to do the job in a joint effort. Although they only finished after the war in 1946, it did not matter. This huge machine was the world's first computer, but it was nothing like our computers today. 课后巩固 多维提能 These pioneers of the 20th century were all dedicated to improving the quality of human life on Earth. Human life on this planet has been transformed into a “global village”， with all the different countries linked in the chain of common interests. There is no doubt about it. Without the breakthroughs of these pioneers in science and technology, whether lucky or planned, the world as we know it today would be a completely different place. 课后巩固 多维提能 √ 1．Why would people have a real dilemma, if they had to choose the single most important discovery of the 20th century? A．Because different people have different ideas and it's difficult to choose. B．Because there were no great discoveries in the 20th century. C．Because there was no common standard to judge. D．Because so many amazing discoveries were made in medicine, communications, transport and many other fields, and they all had a great influence on the world. 课后巩固 多维提能 4 2 3 1 √ 2．How did Einstein think of the equation “E＝mc2”？ A．When he was at work. B．His assistant helped him. C．When he was rocking his one-year-old baby，he was inspired. D．His dream inspired him. 课后巩固 多维提能 4 2 3 1 √ 3．Whose discovery can be used to save people's lives according to the passage? A．Alexander Fleming's. B．The US Navy's. C．Albert Einstein's. D．Eckert and Mauchly's. 课后巩固 多维提能 4 2 3 1 √ 4．What's the original purpose of designing the first computer? A．To do some difficult experiments. B．To improve the accuracy of the missiles. C．To help people make mathematics calculations. D．To replace the missiles，becoming a new weapon. 课后巩固 多维提能 4 2 3 1 [综合能力提升练] Ⅰ.阅读理解 A (2026·石家庄高二月考)Teachers need to fully understand how AI actually works so that they can make wise decisions on when and how to use it. I recently met with a kindergarten teacher who was very worried. She asked me, “Do I really have to use AI with my kids? I don't even know what it is.” She was under such pressure, and that's not healthy. 课后巩固 多维提能 It's an incredibly difficult and unfair situation for teachers to be placed in. That's why AI literacy (人工智能素养), along with supporting teachers with the integration of AI literacy in their classrooms, is a main priority for me. It's very important to slow down and make sure teachers feel comfortable and confident before integrating AI into schools. 课后巩固 多维提能 It's important to think about using AI in ways suitable for different ages and address privacy concerns. While there are still gaps, I remain optimistic. AI can make life easier and help us be more productive and creative if used as a helpful partner. How do these innovations shape the future of education? Are you fearful or hopeful? I'm hopeful that this could be a turning point where teaching and learning are greatly changed, as education has changed little since it began. 课后巩固 多维提能 AI is here to stay, so we have to decide to make it positive in the ways we want. If we don't do anything, it could have negative effects. This feels like a big change, but people were also worried when computers and smartphones were first introduced to schools. We have adapted to those and will adapt to life with AI too. 课后巩固 多维提能 One of the fundamental goals of education is to prepare our students to contribute meaningfully to society. With things changing as rapidly as they are, we need to equip students with the abilities they will need to navigate (导航) and grow in a constantly developing world. We should emphasize learning how to learn and how to adapt. 【解题导语】　本文是一篇说明文。文章提及教师对将AI融入教学的担忧，但作者对AI在教育中的应用持乐观态度，认为需要帮助师生适应，还指出教育应培养学生适应力以应对AI时代。 课后巩固 多维提能 √ 1．What concerned the kindergarten teacher?

A．To cut navigation system cost. B．To make new smartphones. C．To improve navigation system receivers' accuracy. D．To create new correction services. 解析：细节理解题。根据第二段中的“Mohamadi，a doctoral fellow... without depending on expensive external correction services.”可知，穆罕默迪的研究目标是提高导航系统接收器的准确性。 4 5 6 7 8 2 3 1 课后巩固 多维提能 √ 6．Why do navigation system signals fail in cities? A．Signals reflect and are blocked.B．Satellites work poorly in cities. C．Phones lack navigation apps. D．Users walk too slowly. 解析：细节理解题。根据第四段中的“In cities, glass and concrete make satellite signals reflect back and forth...when you enter a built-up area”可知，城市中导航系统信号失效的核心原因是信号来回反射且被阻挡。 4 5 6 7 8 2 3 1 课后巩固 多维提能 √ 7．What can we infer about SmartNav? A．It's a cheap phone app. B．It needs new satellites. C．It's for open motorways. D．It helps self-driving safety. 解析：推理判断题。根据第五段内容可推知，SmartNav有助于自动驾驶安全。 4 5 6 7 8 2 3 1 课后巩固 多维提能 √ 8．What will be the result of the research probably? A．A signal-correcting program. B．A user-friendly type of self-driving car. C．A new navigation system receiver. D．Special building material. 解析：细节理解题。根据第六段中的“The result is a computer program... autonomous vehicles.”可知，研究的最终成果是一个信号校正程序。 4 5 6 7 8 2 3 1 课后巩固 多维提能 Ⅱ.七选五 (2026·清远高二期中)People have always wanted to know what the future will look like.Then, how can we? 1.______________________ ________________________________The world has changed a lot in the last 150 years, but we humans are driven by the same basic needs as we were 150 years ago, such as food, sleep, the feeling of being appreciated and loved. 1．E　解析：上文提到人们总是想知道未来会是什么样子，那么，我们怎么才能知道呢？下文提到过去的150年，空处应回答上文问题且引出下文。E项符合语境。 E.Well, to understand the future, you must know the past. 课后巩固 多维提能 2. ________________________________________ No.In addition, generally speaking, the inventions for the last 150 years have been a human effort for freedom and communication, to be able to get in control of the time and world.Since there is still much to do in this area, this will be the focus at least for the next 150 years. 2．B　解析：根据下文No可知，空处应是一般疑问句。B项符合语境。 B．Will this change in the next 150 years? 课后巩固 多维提能 But why do we need to predict the future?
