These windows use special materials that darken when exposed to sunlight, reducing the need for air conditioning in summer. In winter, they become clearer to let in warmth, cutting heating costs. This technology could significantly reduce energy consumption in homes and offices. Traditional windows contribute to high energy bills because they allow heat to escape in cold weather and let in too much sunlight in hot weather. Smart windows, however, can adjust themselves based on temperature and light conditions, improving energy efficiency by up to 40%. Some versions even generate small amounts of electricity from sunlight, further enhancing their benefits. A current limitation is the high production cost, making these windows expensive for widespread use. Dr. Michael Chen, the lead researcher, says his team is working on cheaper materials and manufacturing methods to make smart windows more affordable. They are also testing long-term durability to ensure the windows last for decades without losing effectiveness.

U2 Digital life知识梳理 U2强化练习 (课文解析&词转专项练习&U2基础&主题阅读)
【课文解析】 Wang Yiming is now calling CS (customer service) to make a complaint. CS: Welcome to Science Power Customer Service. For product information, press [pres]"1". For stores, press"2". For complaints, press"3"... Yiming: (pressing 3) Hello, this (this/that) is Wang. I would like to make a complaint (complain) about the laptop I bought last week. It keeps shutting (shut) down on its own. 教师补充说明： make a complaint 提出投诉 I bought last week”是定语从句，修饰先行词“the laptop”，其中关系代词“that／which”被省略 keep doing sth．表示“一直做某事”，这里表示“一直自动关机”。keep on doing sth．继续做某事（强调不间断） CS: Sorry for the inconvenience (convenient). Can I have your order number, please Yiming: It's 68399. CS: Thank you. Have you tried turning it off and on again 教师补充说明： try doing sth.强调“尝试做某事的行为本身”，通过“做”来体验或探索结果。try to do sth.强调“尽力去做某事”，目的是实现某个目标。 Yiming: Yes. I've repeated (repeat) that a couple of times, but it didn't help! What else can I do CS: I'm afraid I cannot answer this question. Yiming: Wait...Are you a robot CS: Yes, I am. I'll ask our technical support [s p t] team to call you back right away. Would that be okay Yiming: Sure, thanks. CS: You're welcome. Have a nice day! Many people enjoy digital [ d d tl] life. It’s convenient (convenience) and fun. However, in my opinion (在我看来), we should be aware of (意识到) its disadvantages (advantage). First of all, it leads to too much screen time. Some people spend too much time playing computer games(有些人花太多时间玩电脑游戏), watching videos or chatting online, so they have less (less/fewer) time for healthy outdoor activities. Digital life is not always safe. For example, when we visit some websites, hidden (hide) software or viruses on them may collect our personal (person) information. In conclusion (总之), though digital technology brings many benefits (benefit) to our lives, it also causes problems, so we must learn to use it wisely (wise). 教师补充说明： in my opinion=in my view=as far as I’m concerned 在我看来 表达观点：In my opinion .../I believe that.../From my point of view...、It seems to me that.../I strongly feel that... be aware of 意识到＝realize；become aware 变得有意识 引出理由：First of all,.../Secondly,.../What's more,··· leads to 导致=bring about=cause=result in 举例说明：For example, .../For instance,.../Take... as an example. hide／haid／v．藏；隐蔽 过去式：hid 过去分词：hid／hidden draw a conclusion 得出结论、in conclusion 最后、jump to a conclusion匆忙下结论；贸然断定 in conclusion表示“总之”，用于总结观点。常见表示总结的表达还有：to conclude， in summary， to summarize， all in all， in a nutshell，To sum up,，Therefore,，As a result,... though是让步连词，表示“尽管”，相当于although，请注意它与but不连用 表达对比：Although．．．／While．．．／On the one hand,... On the other hand,... benefit from 从······中受益 use sth．wisely 明智地使用某物 Amazing digital technologies Digital technology makes life a lot easier for the disabled (able). For example, a new type [ta p] of smart walking stick for blind people can detect (detection) any object as soon as (一…就…) the person gets close, and then warn (warning) the person of the danger. It can also give directions (direction) and inform its owner of the bus and train timetables. It is believed that this type of technology will make the lives of blind people safer and easier (使盲人的生活更安全、更轻松). 教师补充说明： the disabled 残疾人、be able to do sth. ＝have the ability to do sth.=cando sth.=becapable of doing sth.有能力做某事 warn sb.of sth.提醒某人注意某事 inform sb.of sth.通知某人某事 It is believed that．．．是被动语态的固定句型，表示“人们相信······”，类似的用法还有 It is said that...（据说······）。 make sth．＋形容词 表示“使······变得······” Digital technology makes it easier to share knowledge. It gives students the same chance to learn, no matter where they live. According to (根据;按照) a 2022 report, over 22% of the Indian population cannot read or write. To change this situation, Indian schools in rural [ r r l] areas were provided with a powerful internet connection (connect). Many of the students there didn't have a chance to learn until (conj.) the project started. They can now enjoy wonderful online lessons taught at a top school in New Delhi. 教师补充说明： rural life 乡村生活【近义】suburban adj.郊区的【反义】urban adj.城市的 no matter where...引导让步状语从句，表示“无论在哪里······”，类似的用法还有 no matter when...（无论何时······） provide sb.with-sth..= provide sth. for sb.提供某人某物 “not... untl...”是一个常用的结构，表示“直到······才······”，用来强调某个动作或状态在某个时间点或条件达成之前不会发生。该句型主要用于以下几种情况： （1）表示时间：表示某个动作或状态在某个时间点之前不会发生，直到那个时间点才开始。 （2）表示条件：表示某个动作或状态在某个条件达成之前不会发生，直到那个条件达成才开始。 Firefighting robots are saving lives. They can walk, run, climb and communicate with people caught in a fire. While the robots move around, they send video information to the control unit. In this way (通过这种方式), firefighters can see the fire environment clearly (clear) and then make a safe plan. Robots can really be a great help in dangerous situations. Different digital payment methods Digital wallets A digital wallet allows you to use (use) your mobile phone or smart watch to pay in shops. Simple and safe with a password for protection (protect), it can store all your electronic (electricity) cards. Digital wallets were first used in Sweden瑞典in 1997, but they are now most widely (wide) used in China. 教师补充说明： 形容词短语 simple and safe with a password for protection 在这里作状语，修饰整个句子，说明主语的特点 Quick response code payment快速响应码支付 A quick response (QR) code is a barcode条码your phone can read. Developed in Japan in 1994, QR codes can be used (use) in many ways, such as marketing and information sharing. In China, they are widely used for mobile payments. Digital money Digital money uses software [ s ftwe (r)] codes to work as money over a computer network. It also uses offline technology when there is no network [ netw k]. The People’s Bank of China began working on the e-CNY数字人民币 in 2014, making China a leader in central (centre) bank digital money. 教师补充说明： 与work搭配的介词短语： work for 表示“为······工作”，通常用于表示受雇于某个组织、公司或个人。 work with表示“与······一起工作”，强调合作或共同努力。 work on 表示“致力于做某事”，指正在进行的工作或项 work at表示“在某个地方工作”，通常用于描述工作场所。 work out 表示“解决问题”或“锻炼身体”。 【U2单词】 单词音标词性释义digital/ d d tl/adj.数码的laptop/ l pt p/n.便携式电脑；笔记本电脑desktop/'desktop/n.台式电脑keyboard/'ki b d/n.（计算机或打字机的）键盘bluetooth/'blu tu θ/n.蓝牙（用于手机、计算机等电子设备的短距离无线连接技术）smartphone/'smɑ tf n/n.智能手机headset/'hedset/n.（尤指带麦克风的）头戴式受话器，耳机clear/kl (r)/adj. / v.听得清的；移走，清除（不需要的东西）private/'pra v t/adj.私人的；私密的touch/t t /n. / v.触摸；触觉；触摸；碰touch screen/'t t skri n/n.（计算机）触摸屏advantage/ d'vɑ nt d /n.优点；优势chip/t p/n.芯片lightning/'la tn /adj. / n.闪电般的；飞快的；闪电purple/'p pl/adj.紫色的latest/'le t st/adj.最近的；最新的AI/ e a /abbr.人工智能health/helθ/n.人的身体（或精神）状况；健康complaint/k m'ple nt/n.投诉；抱怨press/pres/v.按，压（使启动）inconvenience/ nk n'vi ni ns/n.不便；麻烦；困难repeat/r 'pi t/v.重复；重做；重说couple/'k pl/n.几个人；几件事物support/s p t/n.（公司向客户提供的）技术支持 freeze/fri z/v.（屏幕）冻结 software/ s ftwe (r)/n.软件 app/ p/n.应用程序；应用软件 network/ netw k/n.（互联）网络 disabled/d s e bld/adj.有残疾的 type/ta p/n.类型；种类 blind/bla nd/adj.瞎的；失明的 detect/d tekt/v.发现；查明；侦察出 object/ bd kt/n.物体；东西 as soon as一...就...warn/w n/v.提醒注意（可能发生的事）；使警惕 direction/d rek n/n.方向；用法说明 inform/ n f m/v.知会；通知 report/r p t/n.调查报告 population/ p pju le n/n.（地区、国家等的）人口，人口数量 rural/ r r l/adj.乡村的；农村的；似农村的 connection/k nek n/n.连接 firefighting/ fa fa t /n.灭火；消防 send/send/v.发送 unit/ ju n t/n.装置；机件 opinion/ p nj n/n.意见；看法 in my opinion依我看 aware/ we (r)/adj.意识到；明白 be aware of知道；意识到；明白 disadvantage/ d s d vɑ nt d /n.不利因素 hide/ha d/v.藏；隐蔽 hidden/ h dn/adj.隐藏的 virus/ va r s/n.病毒conclusion/k n klu n/n.结束；结尾in conclusion最后benefit/ ben f t/n.优势

These windows use special materials that darken when exposed to sunlight, reducing the need for air conditioning in summer. In winter, they become clearer to let in warmth, cutting heating costs. This technology could significantly reduce energy consumption in homes and offices. Traditional windows contribute to high energy bills because they allow heat to escape in cold weather and let in too much sunlight in hot weather. Smart windows, however, can adjust themselves based on temperature and light conditions, improving energy efficiency by up to 40%. Some versions even generate small amounts of electricity from sunlight, further enhancing their benefits. A current limitation is the high production cost, making these windows expensive for widespread use. Dr. Michael Chen, the lead researcher, says his team is working on cheaper materials and manufacturing methods to make smart windows more affordable. They are also testing long-term durability to ensure the windows last for decades without losing effectiveness. If costs decrease, smart windows could become a standard feature in future buildings, reducing global energy demand and greenhouse gas emissions. This innovation represents a major step towards greener architecture. 1. How do smart windows help in summer 2. What percentage of energy efficiency improvement do smart windows provide 3. What is the main obstacle restricting the widespread use of smart windows 4. What is Dr. Chen's team trying to develop 5. How could smart windows impact future buildings 6.
