What Is Digital Literacy (数字素养)
In today’s fast-developing digital world, a new and necessary skill called “digital literacy” is becoming more and more important, especially for middle school students who use phones and computers every day. But what does this skill really mean
Digital literacy is not just about knowing how to turn on a phone or type on a computer. Instead, it includes three clear and key parts. First, technical competence—it means using apps, sending emails, or searching for information with search engines in a proper way. Second, information evaluation (评估), which is the ability to tell real news from fake or misleading information when surfing online. Third, online safety, like protecting your personal data, such as phone numbers and home addresses, and avoiding scams. Most of them look too good to be true.
▲ . For example, when doing homework about science or history, students with good digital literacy can find useful and reliable information quickly on the Internet and check if it comes from trusted sources. They also know better than to share their private details on social media platforms like WeChat or TikTok.
Schools around the world are now starting to teach digital literacy courses to help students. This skill lets young people use technology in a safe and wise way, instead of being confused or harmed by it. As technology keeps growing, digital literacy will be even more necessary for everyone in the future.
41．What is NOT part of digital literacy according to the passage
A．Using search engines correctly B．Telling real news from fake news
C．Fixing broken computers by oneself D．Protecting personal online data
42．Why do schools teach digital literacy to students
A．To help students buy cheap phones B．To let students use technology safely and wisely
C．To ask students to spend more time online D．To prepare students for computer competitions
43．Which of the following can be put in “ ▲ ” in paragraph 3
A．Digital literacy is useless for daily life B．Digital literacy shows up in many situations
C．Fake news is easy to find online D．Social media is popular among students
44．The underlined word “scams” probably means “________” in English.
A．tricks B．courses C．devices D．privacy
45．What is the best title for the passage
A．How to Use Search Engines B．The Dangers of Social Media

1．C
【解析】句意：我叔叔自2018年以来就在这家数字公司工作。
since自从；for持续……。for后面要接一段时间，since后面接过去的时间点，2018是具体的过去年份（时间点），所以第二空只能用since，直接排除B、D选项。since+过去时间点的结构要和现在完成时搭配，表示动作从2018年开始一直持续到现在，因此第一空用现在完成时has worked。
2．A

【解析】16．句意：它使世界成为一个更好的居住地方。
根据前一句“Technology is changing our lives every day.”（科技每天都在改变我们的生活）以及后文“Many new things come out to help people with their daily life.”（许多新事物出现来帮助人们的日常生活），可知科技让居住的世界变得“更好”。

19．句意：我妈妈喜欢这种方式，因为她可以和她另一个城市的妹妹交谈，而不用付任何钱。
根据语境在线聊天免费，可知用without表示否定，表示“没有/不用”。
20．句意：但是今天的电脑小且轻。
前文提到过去的电脑大且重（big，heavy），现在的电脑小（small），与之相对的应该是“轻的”（light），便于携带。

spend time doing sth.意为“花费时间做某事”，play games是“玩游戏”，固定搭配。
26．句意：所以，我们需要以正确的方式使用科技。
前文说科技带来了一些问题，那么我们就需要用“正确的”（right）的方式使用科技。
27．句意：我们应该记住科技旨在帮助我们，而不是控制我们。
根据“not to control”可知，科技是为了“帮助”（help）我们，而不是控制。
28．句意：它是一个有用的工具，但我们应该知道何时关掉它并享受我们周围真实的世界。
but表示转折，它虽然有用但我们为了“enjoy real world”（享受真实的世界），应该知道何时停止使用，所以，“turn off“关掉”符合题意。
29．句意：谁知道未来什么将成为可能。
后文提到机器人、去月球等，可知事物会变得可能，“possible可能的”符合语境。
30．句意：无论发生什么，我们都应该准备好面对新世界。

45．文章通篇围绕“Digital Literacy”展开，第一段引出话题，第二段定义及组成部分，第三段举例，第四段总结其重要性。选项C“一项关键技能：数字素养”最能概括全文中心思想。选项A、B、D均为文章提及的细节，不足以作为标题。
46．digital
【解析】句意：许多新的数码产品将会在科技展览上展出。空格修饰名词products，要用形容词；digital本身就是形容词，意为“数码的”，因此应填digital。
47．pollution
【解析】句意：你曾经思考过由电子垃圾造成的污染吗。定冠词the后需要接名词，pollute是动词，表示“污染”，要变为名词形式pollution表示“污染”，故填pollution。
48．education
【解析】句意：网络教育在农村地区越来越受欢迎。空格处位于形容词Online之后，系动词is之前，在句中充当主语的核心词，因此需要填入名词形式，educate是动词，名词形式是education，为不可数名词。
49．avoid
【解析】句意：我们应该学会在课堂上避免不必要的数字干扰。固定搭配learn to do sth.意为“学习做某事”，其中to是不定式符号，后面必须接动词原形avoid。
50．inventions
【解析】句意：智能手机是21世纪最伟大的发明之一。 固定结构“one of+the+形容词最高级+可数名词复数”意为“最……之一”；invent是动词，表示“发明”，名词invention表示“发明”，复数形式为inventions，符合语境。故填inventions。
51．develop
【解析】句意：在使用数字设备时，这是一个发展我们自控能力的好机会 。句子为it作形式主语的固定句型： It is + 名词 (a chance /a good idea…) + to do sth.“做某事的好机会/好主意”，to后接动词原形，构成不定式，做真正的主语；中文“发展”对应动词develop，用原形。
52．convenience
【解析】句意：网上购物给我们带来了很大的便利，节省了很多时间。空格前形容词great后需要接名词作动词brings的宾语；中文提示为“便利”，对应的英文名词是convenience，为不可数名词。
53．communication
【解析】句意：良好的沟通技巧在网上和现实生活中都很有必要。 “交流” 动词是communicate；此处修饰名词skills，要用名词communication。communication skills意为“沟通/交流技巧”。
54．harmful
【解析】句意：每天长时间看电子屏幕对我们的眼睛有害。根据句意及汉意提示，此处对应单词harmful，固定搭配be harmful to意为 “对……有害的”，符合题意。
55．privacy
【解析】句意：使用网络平台时保护个人隐私十分重要。形容词personal后需要搭配名词；中文提示“隐私”对应的不可数名词为privacy，personal privacy表示“个人隐私”，符合句子结构。
56．If will protect
【解析】原句中“如果”和“保护”为关键信息，If引导条件状语从句，遵循“主将从现”规则，从句用一般现在时，主句使用一般将来时will do；protect意为“保护”，用原形即可。
57．opinion/view
【解析】原句中的“在她看来”是关键词，“在某人看来”的常用固定短语是“in one’s opinion/view”。空格前her是形容词性物主代词，后面接名词opinion/view。
58．more beautiful
【解析】原句中“比……更美丽”是关键词。根据中文“比……更美丽”以及英文句中的关键词than，可知此处需要使用形容词的比较级。“美丽”的英文单词是beautiful，beautiful是多音节形容词，变比较级时不能在词尾加-er，而需要在词前加more，因此“更美丽”翻译为more beautiful，对应两个空格，符合题意。
59．
stronger and stronger
【解析】原句中的“越来越强大”是关键词。“比较级+and+比较级”表示“越来越……”，强大的英文是strong，比较级为stronger，故填stronger and stronger。
60．
effect / influence/ impact
【解析】原句中的“影响”是关键词，表示“影响”用effect/influence/impact，有不定冠词a修饰，用单数名词。
61．has changed 62．to communicate 63．their 64．easier 65．studies 66．playing 67．to cheat 68．to use 69．with 70．make
【导语】本文讨论了科技给生活带来的便利以及过度使用手机带来的问题，并提出了合理使用科技的建议。
【解析】61．句意：近年来，科技极大地改变了我们的生活。时间状语“these years”常与现在完成时连用，主语Technology为第三人称单数，故填has changed。
62．句意：人们使用智能手机相互交流、学习新事物和娱乐。“use sth. to do sth.”意为“用某物做某事”。
63．句意：许多学生甚至用手机在线做作业。修饰名词phones，需用形容词性物主代词，they的对应词为their。
64．句意：虽然科技让我们的生活更轻松，但它也带来了一些问题。make sth.+形容词比较级，表示“使……更……”，easy的比较级为easier。
65．句意：一些学生对手机感兴趣，忽视了学业。study意为“学业”时，常用复数形式studies。
66．句意：他们花太多时间玩游戏或看视频。“spend time (in) doing sth.”意为“花费时间做某事”。
67．句意：更糟糕的是，一些学生在课堂上用手机作弊。此处用动词不定式作目的状语，故填to cheat。
68．句意：为了解决这些问题，我们应该学会明智地使用技术。“learn to do sth.”意为“学会做某事”。
69．句意：我们在学习或与家人吃饭时应该关掉手机。“have meals with...”意为“和……一起吃饭”。
70．句意：这样，我们可以让技术成为我们的好帮手，而不是主人。情态动词can后接动词原形。
71．例文
Dear John,
I’m glad to tell you something about my digital life.
I enjoy my digital life because it makes everything more convenient. Besides, it helps me widen my horizons easily. I often use mobile payment and educational apps. For example, I use Alipay when shopping, and “English Listening and Speaking” for English practice. These tools are very helpful.
I think it’s important to use digital tools properly. We shouldn’t spend too much time on them, or it will be bad for our health. What about your digital life Looking forward to your reply.
Yours,
Li Ming
