For many of them, the Internet remains a place where a stranger can steal their (1)________ and post (2)________ photos of them under a (3)________ name. One girl said she felt (4)________ after her photo was shared again and again. 我的答案：(1)________　(2)________　(3)________　(4)________ 提到上网的风险，最先跳出来的三个英文词通常是 virus、hacker、password。三个词都对，问题在它们把风险画成了「机器对机器」：病毒入侵、黑客破解、密码被偷。 翻开本单元 Reading for Writing 的安全博客，排在最前面的是 identity theft，紧随其后是 troll 与 cyberbully。施动者变了——拿走你住址和电话的是人，躲在屏幕后挑事嘲弄的也是人。 风险环的施动者是人。选项里挤满 device、system、program，原文却在讲有人拿走了什么信息，这类选项直接划掉。 下面三句来自真实的作业本，三句全错，病因还不在同一层。 1. I am convenient to shop online. 2. This app is very benefit for my study. 3. Don't click the strange file, it may have virus. 第 1 句错在主语与表语的搭配层。convenient 作表语，主语只能是事、物、时间、地点或形式主语 it，人不能作它的主语。汉语说「我很方便」，英语要把方便落到那件事上：It is convenient for me to shop online. 它是本单元出现率最高的一处汉语负迁移。 第 2 句错在词性判断层。benefit 是名词或动词，不能充表语形容词；表「有益的」用 beneficial，改用名词则说 This app is of great benefit to my study. 主课文里 one of the greatest benefits of the Internet 的 benefits 是名词复数，how technology benefits people's daily lives 的 benefits 是及物动词第三人称单数——同一个词，教材里两种词性都露过面。 第 3 句错在名词的数与介词遗漏两层。virus 表「病毒」可数，泛指用 a virus 或 viruses，不能裸用；click 后接宾语时教材用 click on。改成 Don't click on the strange file; it may contain a virus.（原句用逗号直接连两个完整句，另有逗号拼接的问题。） 先说清错在哪一层，再动手改。只改单词不说层次，下一次照错。 风险词的方向一摆正，九个词就有了挂靠：偷身份的 privacy、identity、theft，挑事的 troll、false、rude，盯人霸凌的 cyberbully、target、particular、embarrassing，结果是 upset。 3、 核心精讲：四环语义链上的词形与词义 四环的划分依据是教材两篇文本的叙事顺序。Reading and Thinking 里 Jan 困守家中，上网后不再孤单，继而开办 IT 俱乐部教老年人用电脑，走的是连接与便利；Reading for Writing 的安全博客先讲不舒服就离开，再讲保护隐私，最后讲礼貌待人，走的是风险与对策。两篇合起来是一条链：连接 → 便利 → 风险 → 对策。 一个词可以跨环出现：database 在连接环里是存信息的库，在便利环里是查得快的资源；update、click 同理。归位看它在教材语境里干什么活。 （1） 第一环·连接：三个动作的分工 本单元「上网」的动词是 surf，教材写的是 surfing the Internet could help her feel less lonely and bored。三个动作常被混排着考，分工如下： 动作 后接对象 判定要点 常见错误 surf the Internet / the web 强调四处浏览 写成 play computer、go on the net search for + 目标 强调找特定信息 search 后直接接目标，漏 for click on + 宾语 介词 on 不丢 click the link 漏 on access 的词性按成分定，不按口诀。 同一个 access，在 I have access to the Internet 里是名词，在 Students can access the Internet 里是动词，两句只差前面那一个词。 access 前站的是 have 还是 can，词性当场就定。 have access to 是「名词 + 介词」块，to 是介词，后面接名词或动名词，不接动词原形；access 作及物动词时，前面站的是情态动词、助动词或不定式符号 to。判定就看它前面那一个词：have、easy、with → 名词；can、will、to → 动词。 错例：I have access to use the Internet. 把介词 to 当成了不定式符号，后面又接动词原形；改法是 I have access to the Internet 或 I can access the Internet。反过来，题干给 Easy ________ to the Internet is what we need，空前 Easy 是形容词，只能修饰名词，填 access。 主课文里还有一处画面感很强的表达：bridge the digital divide and make sure that everyone has access to the Internet。写「让每个人都能用上网络」，用这一句比 Everyone should use the Internet 更有层次。 三个动作放在一起看，介词与宾语是绑定的：surf 直接接对象，search 靠 for 引出目标，click 靠 on 接宾语。 Isurf the Internet for opera videos.（四处浏览） IIsearch for the latest information on the app.（找特定信息） Never click on a strange link.（点击后接 on） Jan 的落脚点落在一个具体的人群——she joined an online group where she could talk about her problems and get support and advice from others。network 指结构（social networks），community 指一群人（online communities）。阅读题问「什么改变了 Jan」，回原文锁定 joined an online group 这一句，别凭 network 去猜。 即时练习（第一环·连接）： Since last spring, my grandpa (1)________ (surf) the Internet for opera videos every morning. With easy (2)________ (accessible) to a health app, he can keep track (3)________ his blood pressure. What surprised him most was that he could (4)________ (access) a free course for older learners. 我的答案：(1)________　(2)________　(3)________　(4)________ （2） 第二环·便利：benefit 的判定有先后 第二环的代表词是 convenient 与 benefit，两处都是词性转换的高频面孔。 benefit 一名三形：名词 benefit（益处）、及物动词 benefit（使受益）、不及物 benefit from（得益于）、形容词 beneficial（有益的）。语法填空给 benefit 挖空，四个词形都可能是对的。 空后有 from，词性立刻定死。 先看空后：空后有 from → 不及物动词 benefit；空后直接接宾语、中间无介词 → 及物动词（第三人称单数 benefits）。这两条只要命中，词性当场就定，不必再往前看。 空后定不了，再查空前：先看有没有 of——of great benefit to 里 of 的优先级高于 be；再看修饰语，a、the、great、形容词性物主代词 → 名词（复数 benefits）；以上都不成立，空前是 be、more、most、very → 形容词 beneficial。 错例：This new app is of great ________ to my study. 空前是 be，按「空前是 be 就填形容词」的口诀会填 beneficial，可空前紧挨着 of，得填名词 benefit。先查 of，这个坑就绕过去了。 convenient 的主语限制用两组对比例句并置看： The chair is comfortable.（椅子坐上去舒服，comfortable 讲身体感受） It is convenient for me to pay by phone.（付款这件事省事，convenient 讲做事的难易） convenient 作表语，主语只能是事、物、时间、地点、安排或形式主语 it。 Are you convenient? 是高频病句。问「你这周末方便吗」，得把方便落到那件事上——Is the weekend convenient for you? 或 If it is convenient for you… convenient 说的是事省不省事，comfortable 说的是身体舒不舒服。 convenient 描述一件事做起来省不省事，语义指向事件本身，人只能作 for 的宾语；comfortable 描述身体舒不舒服，语义指向感受者，所以人、椅、床都能作它的主语。 错例反着来：The Internet makes our lives more convenient. 这句成立。主语限制管的是「作表语时」的主语，作宾语补足语时补足的仍是 our lives 这件事，不指向人。 update 一家三层：update 动名同形（更新／最新消息），updated 是过去分词作定语表「被更新过的」，up-to-date 是形容词表「最新的」，最高级写 the most up-to-date；要表达「最新信息」，优先用 the latest information 或 the most up-to-date information。 抽象名词前面加修饰语，是提升表达层次最省力的一手：full use、great benefit、easy access、up-to-date information。 判定填空（第二环·便利）： Online dictionaries are of great (1)________ (benefit) to my vocabulary building, and I (2)________ (benefit) a lot from reading real examples. It is very (3)________ (convenience) for me to look up a word on my phone, and the (4)________ (update) version even marks the most up-to-date meanings. 我的答案：(1)________　(2)________　(3)________　(4)________ （3） 第三环·风险：链条的两端都是人 按「人伤人」这条线记，九个词自动成串，还能预判下文走向：读到「有人拿到了你的信息」，下文多半是身份被盗；读到「有人反复嘲弄同一个人」，下文多半是霸凌。 链条位置 词 判定要点 偷身份 privacy / identity / theft / steal privacy 不可数；identity theft 作整体词块，不拆拼；identity thief 指人 挑事 troll / false / rude troll 常用 several false names，无特定对象 霸凌 cyberbully / target / particular / embarrassing directed at particular people，贴 embarrassing photos 情感结果 upset / lonely / tough / stuck upset 三形合一，不写 upsetted 教材给过两个定义：troll 是 a person who posts comments or questions in order to stir up trouble online，常使用 several false names；cyberbully 是 uses the Internet to be mean to others，内容 directed at particular people，还会贴 embarrassing photos。两词都含 mean（待人刻薄）之意。 有没有特定的人——这就是 troll 与 cyberbully 的分界线。 分界不在用词狠不狠，而在对象是不是特定的某个人。四处挑事、谁撞上算谁，是 troll；认准一个人反复嘲弄，是 cyberbully。题干问「针对某个人」，落 cyberbully；问「纯粹捣乱」，落 troll。 错例：一个人先用几个假名到处挑事，后来盯住同班同学反复攻击并贴出照片。按行为落点判 cyberbully，判据是他最后有没有特定目标，与此前用什么名字无关。完形里看到 He posted rude comments under several false names 判定为 troll，是因为证据停在 several false names；同一段若再出现 the same classmate、again and again，就得改判。 privacy 是名词且不可数，private 是形容词：protect your privacy / a private chat。语法填空给 privacy 挖空，空前是形容词性物主代词或及物动词 → 名词 privacy；后面紧接名词需要修饰 → private。 identity theft 当作整体词块记，译作「身份盗窃」。教材相邻两句给了动词版和名词版：Someone might use the information to steal your identity. 与 Identity theft is a common and serious problem. 名词术语题怎么定位？回原文找它的动词定义句——「用信息做什么」，答案常就藏在同一句的上半句。 embarrassing 修饰物或事，embarrassed 修饰人，教材用的是 embarrassing photos。upset 三形合一：upset—upset—upset，形容词与动词同形，The girl was very upset / It upset her。 「被取笑」在完形里的正确项常是被动结构 be made fun of。Amy 的留言给过完整形态：A photo of her had been posted online and she was being made fun of——had been posted 是过去完成时的被动，was being made fun of 是过去进行时的被动。 stuck（困于）与 tough（艰难的）常被人塞进风险环，其实它们出自 Jan 故事：she found herself out of work and stuck at home，When you go through tough times。它们写人的处境与情感结果，不在「人伤人」链条上，单列一处记，免得在完形里把「处境艰难」读成「被人攻击」。 链条回填（第三环·风险）： Someone might use the information to (1)________ (stealing) your identity, and identity (2)________ (thief) is a common and serious problem. A photo of her had been posted online and she was being made fun (3)________ . She felt (4)________ (embarrass) and more than a little upset. 我的答案：(1)________　(2)________　(3)________　(4)________ （4） 第四环·对策：三条 guideline 各有触发条件 安全博客给出的 guideline 只有三条，每条都带一个触发条件，写作时照骨架换名词即可： 顺序 行动 触发条件 原句要点 一 leave the site 看到、读到让你不舒服的东西 leave the site immediately; don't post comments or click on anything 二 protect your privacy 有人索要住址、电话一类个人信息 don't give out your address or phone number 三 be polite 网上发言，不挑事不霸凌 being online is no excuse for being rude 第1条 最容易被记错。判定标准落在「你看到、读到时舒不舒服」，与对方要不要你的密码无关——If you see or read something that makes you feel uncomfortable, leave the site immediately. 这一条里同时藏着 click on 接宾语的出处：Don't post comments or click on anything. 第2条 把风险环和对策环扣在了一起：You don't want to become a target for a troll or cyberbully. 说话留分寸，就是不给别人把你当目标的理由。 三条 guideline 直接改写就是考场上的行动句： If you see or read something that makes you feel uncomfortable, leave the site at once. Never give out your personal information such as your address or phone number. Always be polite online so that you won't become a target for cyberbullies. 博客末句用的是：the more polite you are, the less likely it is you will be attacked。两个 the 后面都接比较级，后半句可倒装也可不倒装。 now that 作连词短语表「既然、由于」，引导原因状语从句，后面接既成的事实或状态；in particular 是介词短语作状语，与形容词 particular 同源，分工落在词性上。guideline 与 tip 都是可数名词，写 guidelines、tips。 charity、go through、inspire 常被挂到对策环上，其实它们属于 Jan 故事的后半段：困境（go through tough times）→ 触动（inspired）→ 行动（start a charity website）。记在 Jan 这条线上，写作时才不会串味。 词块回填（第四环·对策）： (1)________ that you have a smartphone, keep a safety rule (2)________ mind: leave the site the moment something makes you feel (3)________ (comfort). Never give (4)________ your address, (5)________ particular when a stranger asks for it. 我的答案：(1)________　(2)________　(3)________　(4)________　(5)________ 4、 引导练习：先自判，后对照 下面八空先自己推，写完再对答案。 The 2026 National Cybersecurity Week ran from September 14 to 20, with its main events in Jinan. Its theme put the focus on people rather than machines. During those days, a speaker at our school said the Internet is very (1)________ (convenience), and every student should have (2)________ to it. Yet easy access also means someone might use our information to steal our (3)________ (identify). Identity (4)________ (thief) is a common and serious problem. Being rude online can make us a (5)________ for a cyberbully. The more polite we are, the less (6)________ (likely) we are to be attacked. Keep two rules (7)________ mind: protect your (8)________ (private), and never give out your address. 【定位提示】(2)(5)(7) 看空前后的搭配缺了哪一块；(3)(4)(8) 看括号里的词该换成什么词性。 我的答案：(1)________　(2)________　(3)________　(4)________　(5)________　(6)________　(7)________　(8)________ 卡住的空回看空前的那一个词：第 (2) 空前是 have，只能填名词 access；第 (5) 空 target 可数，单数前加 a；第 (6) 空比较级并列结构填 likely 原形；第 (8) 空 your 后接不可数名词 privacy。 5、 高频易错速查表 判定信号 易错等级 本讲结论 access 前有 have、easy、with → 名词，后接 to 且 to 是介词；前有 can、will、to → 动词。错例：I have access to use the Internet.（介词 to 后接原形，错） 高 前置词定词性 convenient 作表语，主语是事、物、时间、地点、it → 正确；主语是人 → 改 Is the weekend convenient for you? 错例：Are you convenient? 高 方便指向事，不指向人 benefit 空后有 from → 动词；空前有 of → 名词；空前是 a、the、great、my → 名词；以上都不成立且空前是 be、very → beneficial。错例：be of great benefit to（空前是 be 仍填名词） 高 先看空后，再查 of privacy、identity 出现在 our、your 或及物动词后 → 名词，无复数；后面紧接名词需要修饰 → private。错例：identity thief（指盗用身份的人） 中 不可数，不拆拼 读到无特定对象的挑衅、several false names → troll；读到 particular people、反复同一个人 → cyberbully。错例：先用假名挑事、后盯住一人 → 按落点判 cyberbully 高 看有没有特定目标 click 后接宾语 → click on，介词不丢；surf 后接 the Internet，search 后接 for + 目标 中 介词与宾语绑定 keep track of、make full use of 的 of 不丢；make full use of 不带褒贬，take advantage of 接机会、漏洞时常含贬义 中 抽象名词前加修饰语 -ing 修饰物或事（embarrassing photos），-ed 修饰人（felt embarrassed） 中 修饰对象决定形式 upset 三形合一：upset—upset—upset，动词与形容词同形，不写 upsetted 低 不规则的规则 now that + 既成事实或状态，引导原因状语从句；in particular 作状语，particular 是形容词 中 连词短语接事实 updated 是被更新过的（定语），up-to-date 是最新的，最高级写 the most up-to-date 中 分层使用 guideline、tip 可数，写 guidelines、tips；leave the site 后不接 on 低 可数与搭配 6、 特殊结构与句式 now that 引导原因状语从句，后面接已经成立的事实或状态，时态多用现在完成时或一般现在时；它与 because 的分工在「既成」二字上：now that you have a smartphone 说的是你已经有了手机这一事实。 the + 比较级…, the + 比较级… 表「越……越……」，两个 the 后面都接比较级，后半句可倒装也可不倒装：the more polite you are, the less likely it is you will be attacked。 -ing 与 -ed 形容词的分界在修饰对象：embarrassing photos（照片令人难堪）／felt embarrassed（人感到难堪）。upset 则三形合一，动词与形容词同形。 语法填空不给提示词的空，先分虚实：句子成分完整、只缺连接或关系 → 虚词（连词、介词、关系词）；成分残缺、需要一个实义词 → 实词。本讲的 to、of、in 都属虚词，靠固定块判定；a 属冠词，靠名词的可数性判定。同一个位置填什么，取决于前面那个词是可数单数还是不可数：a target 成立，privacy 前就不填 a。 被动语态在本单元两篇文本里密集复现：Much has been written about the wonders of the World Wide Web（现在完成时的被动）；A photo of her had been posted online and she was being made fun of（过去完成时被动 + 过去进行时被动）。完形考「被取笑」，正确项常是这个被动结构。 Now that our school (1)________ (join) the 2026 Cybersecurity Week activities, we have put up a poster in the hallway. It says: keep three rules (2)________ mind. The (3)________ (update) guide beside it lists them clearly, and the most up-to-date tips came from the local police. Anyone who finds an (4)________ (embarrass) photo of themselves online may feel upset; the more carefully we guard our personal details, the less likely we are (5)________ (become) a target for cyberbullies. 我的答案：(1)________　(2)________　(3)________　(4)________　(5)________ 7、 听力：态度与转变（附带覆盖） 本单元听力话题围绕上网活动与安全，说话人习惯先肯定便利、再转折到风险、最后给出限定性主张。只听前半句就落笔的，选中的往往正是被他反驳的那一项。 转折之后才是落点，转折之前都是铺垫。 but、however、still、to be honest 之后转向真实态度；I'd say…、The key is…、It works best when… 之后是主张所在。听力材料的结构与教材安全博客同构——先说现象，再给规则，等的就是转折那一下。 错例反着来：独白通篇没有转折词时，按首尾句与语气词判——开头给背景，结尾给总结或主张，excited、upset、worried 一类词直接透露倾向。这时死等 but，整段就空过了。 干扰项的三副面孔：绝对化（totally、too…to、everywhere）；偷换对象（把工具说成替代品、把部分说成全部、把个人的做法说成普遍要求）；时间错位（把 I used to… 里的旧做法当成现在的态度）。 听下面一段独白，回答第 1—2 题。 1.

Ten of the largest platforms face fines of up to 33 million dollars if they fail to take reasonable steps to block Australian users younger than 16. In July 2026, the country's internet regulator, eSafety, released a study with an uncomfortable finding: more than eight in ten under-16s are still using social media. Before the ban, nearly 86 percent of the children surveyed reported using at least one age-restricted platform; three months after it took effect, the figure was still above 81 percent. About 58 percent of teenagers said they used social media every day, compared with roughly 60 percent before. Around half of the children who kept their accounts said the platforms had not checked their age. eSafety named the platforms' failure to put in place effective age checks as the main reason. The government says the rule is about protecting children from cyberbullying and harmful content. Reddit, one of the ten platforms, has challenged the ban in the High Court while continuing to follow it. 1. What did the eSafety study in July 2026 find? A. The ban has removed most teenage accounts. B. Teenagers have stopped using social media at school. C. Most under-16s are still using social media. D. Platforms have checked every user's age. 我的答案：________ 2. Why could many children keep their accounts according to eSafety? A. Their parents helped them hide their age. B. The government cancelled the fines. C. They moved to video game platforms. D. The platforms failed to check ages effectively. 我的答案：________ 3. What can be inferred from the numbers in the passage? A. Daily use has changed little since the ban. B. More teens started using social media after the ban. C. Age checks have become stricter over time. D. Half of the children deleted their accounts. 我的答案：________ 4. What is the writer's attitude towards the effect of the ban? A. Uninterested. B. Fully supportive. C. Totally against it. D. Doubtful about it. 我的答案：________ C 档·冲刺挑战｜完形填空 阅读下面短文，从每题所给的 A、B、C、D 四个选项中选出可以填入空白处的最佳选项。 Last winter, a girl in our class received a voice message from "her father".

The reason is simple: rudeness attracts the wrong kind of attention. A person who posts comments just to stir up trouble is called a troll; such a person often hides behind several false names and picks on whoever passes by. A cyberbully works differently. The meanness is directed at particular people, again and again, sometimes with embarrassing photos posted for everyone to see. The line between the two is drawn by one thing: whether there is a chosen target. These habits protect the person who keeps them as much as the person they are aimed at—rudeness makes you a target, too. The blog's last line puts it neatly: the more polite you are, the less likely it is you will be attacked. 1. What does the underlined word "meanness" most probably mean?

To close such gaps, ITU and UNICEF run an initiative called Giga, which has mapped connectivity in over 2.2 million schools in more than 40 countries and has helped connect tens of thousands of schools. Another programme, Partner2Connect, has gathered more than 82 billion dollars in pledges to support meaningful connectivity in developing countries. For students, the meaning of these numbers is concrete. A school with a connection can offer online lessons, digital libraries and safe search tools; a school without one cannot. Teachers in connected schools report that students who once walked miles for a reference book now keep track of the latest information on a shared screen. Connectivity alone will not do, though. Young people also need the skills to tell a reliable source from a copied one, and the habits to protect their privacy while online. That is why ITU has joined an AI Skills Coalition with partners across the United Nations, the private sector and universities. 1. What does the initiative Giga do? A. It builds new schools in 40 countries. B. It trains teachers to use AI tools. C. It maps school connectivity and helps connect schools. D. It sells devices to low-income families. 我的答案：________ 2. How much has Partner2Connect gathered in pledges? A. 8.2 billion dollars. B. 82 billion dollars. C. 2.2 billion dollars. D. 820 million dollars. 我的答案：________ 3. What does the last paragraph suggest about connectivity? A. It has closed the digital divide completely. B. It matters less than buying new devices. C. It should replace classroom teaching. D. It works only together with skills and safe habits. 我的答案：________ 4. What is the writer's attitude towards connecting schools? A. Supportive, yet not content with connection alone. B. Doubtful about its value. C. Totally against it. D. Uninterested in the numbers. 我的答案：________ （3） 完形填空 阅读下面短文，从每题所给的 A、B、C、D 四个选项中选出可以填入空白处的最佳选项。 Last month our school called for volunteers for a community book drive.

For many of them, the Internet remains a place where a stranger can steal their (1)________ and post (2)________ photos of them under a (3)________ name. One girl said she felt (4)________ after her photo was shared again and again. 【答案】(1) identity　(2) embarrassing　(3) false　(4) upset 解析：第 (1) 空 steal 后接名词宾语，steal one's identity 是固定搭配；第 (2) 空修饰 photos，用 -ing 形式 embarrassing；第 (3) 空 under a false name 是教材出现过的搭配；第 (4) 空 feel 后接形容词 upset。四空全落在「人伤人」这条线上。 提到上网的风险，最先跳出来的三个英文词通常是 virus、hacker、password。三个词都对，问题在它们把风险画成了「机器对机器」：病毒入侵、黑客破解、密码被偷。 翻开本单元 Reading for Writing 的安全博客，排在最前面的是 identity theft，紧随其后是 troll 与 cyberbully。施动者变了——拿走你住址和电话的是人，躲在屏幕后挑事嘲弄的也是人。 风险环的施动者是人。选项里挤满 device、system、program，原文却在讲有人拿走了什么信息，这类选项直接划掉。 下面三句来自真实的作业本，三句全错，病因还不在同一层。 1. I am convenient to shop online. 2. This app is very benefit for my study. 3. Don't click the strange file, it may have virus. 第 1 句错在主语与表语的搭配层。convenient 作表语，主语只能是事、物、时间、地点或形式主语 it，人不能作它的主语。汉语说「我很方便」，英语要把方便落到那件事上：It is convenient for me to shop online. 它是本单元出现率最高的一处汉语负迁移。 第 2 句错在词性判断层。benefit 是名词或动词，不能充表语形容词；表「有益的」用 beneficial，改用名词则说 This app is of great benefit to my study. 主课文里 one of the greatest benefits of the Internet 的 benefits 是名词复数，how technology benefits people's daily lives 的 benefits 是及物动词第三人称单数——同一个词，教材里两种词性都露过面。 第 3 句错在名词的数与介词遗漏两层。virus 表「病毒」可数，泛指用 a virus 或 viruses，不能裸用；click 后接宾语时教材用 click on。改成 Don't click on the strange file; it may contain a virus.（原句用逗号直接连两个完整句，另有逗号拼接的问题。） 先说清错在哪一层，再动手改。只改单词不说层次，下一次照错。 风险词的方向一摆正，九个词就有了挂靠：偷身份的 privacy、identity、theft，挑事的 troll、false、rude，盯人霸凌的 cyberbully、target、particular、embarrassing，结果是 upset。 3、 核心精讲：四环语义链上的词形与词义 四环的划分依据是教材两篇文本的叙事顺序。Reading and Thinking 里 Jan 困守家中，上网后不再孤单，继而开办 IT 俱乐部教老年人用电脑，走的是连接与便利；Reading for Writing 的安全博客先讲不舒服就离开，再讲保护隐私，最后讲礼貌待人，走的是风险与对策。两篇合起来是一条链：连接 → 便利 → 风险 → 对策。 一个词可以跨环出现：database 在连接环里是存信息的库，在便利环里是查得快的资源；update、click 同理。归位看它在教材语境里干什么活。 （1） 第一环·连接：三个动作的分工 本单元「上网」的动词是 surf，教材写的是 surfing the Internet could help her feel less lonely and bored。三个动作常被混排着考，分工如下： 动作 后接对象 判定要点 常见错误 surf the Internet / the web 强调四处浏览 写成 play computer、go on the net search for + 目标 强调找特定信息 search 后直接接目标，漏 for click on + 宾语 介词 on 不丢 click the link 漏 on access 的词性按成分定，不按口诀。 同一个 access，在 I have access to the Internet 里是名词，在 Students can access the Internet 里是动词，两句只差前面那一个词。 access 前站的是 have 还是 can，词性当场就定。 have access to 是「名词 + 介词」块，to 是介词，后面接名词或动名词，不接动词原形；access 作及物动词时，前面站的是情态动词、助动词或不定式符号 to。判定就看它前面那一个词：have、easy、with → 名词；can、will、to → 动词。 错例：I have access to use the Internet. 把介词 to 当成了不定式符号，后面又接动词原形；改法是 I have access to the Internet 或 I can access the Internet。反过来，题干给 Easy ________ to the Internet is what we need，空前 Easy 是形容词，只能修饰名词，填 access。 主课文里还有一处画面感很强的表达：bridge the digital divide and make sure that everyone has access to the Internet。写「让每个人都能用上网络」，用这一句比 Everyone should use the Internet 更有层次。 三个动作放在一起看，介词与宾语是绑定的：surf 直接接对象，search 靠 for 引出目标，click 靠 on 接宾语。 Isurf the Internet for opera videos.（四处浏览） IIsearch for the latest information on the app.（找特定信息） Never click on a strange link.（点击后接 on） Jan 的落脚点落在一个具体的人群——she joined an online group where she could talk about her problems and get support and advice from others。network 指结构（social networks），community 指一群人（online communities）。阅读题问「什么改变了 Jan」，回原文锁定 joined an online group 这一句，别凭 network 去猜。 即时练习（第一环·连接）： Since last spring, my grandpa (1)________ (surf) the Internet for opera videos every morning. With easy (2)________ (accessible) to a health app, he can keep track (3)________ his blood pressure. What surprised him most was that he could (4)________ (access) a free course for older learners. 【答案】(1) has surfed　(2) access　(3) of　(4) access 解析：第 (1) 空 Since last spring 提示现在完成时，填 has surfed；第 (2) 空 easy 修饰名词 access；第 (3) 空 keep track of 的 of 不能丢；第 (4) 空 could 后接动词原形 access。两空考同一个词的两种词性，判据全在前置词上。 （2） 第二环·便利：benefit 的判定有先后 第二环的代表词是 convenient 与 benefit，两处都是词性转换的高频面孔。 benefit 一名三形：名词 benefit（益处）、及物动词 benefit（使受益）、不及物 benefit from（得益于）、形容词 beneficial（有益的）。语法填空给 benefit 挖空，四个词形都可能是对的。 空后有 from，词性立刻定死。 先看空后：空后有 from → 不及物动词 benefit；空后直接接宾语、中间无介词 → 及物动词（第三人称单数 benefits）。这两条只要命中，词性当场就定，不必再往前看。 空后定不了，再查空前：先看有没有 of——of great benefit to 里 of 的优先级高于 be；再看修饰语，a、the、great、形容词性物主代词 → 名词（复数 benefits）；以上都不成立，空前是 be、more、most、very → 形容词 beneficial。 错例：This new app is of great ________ to my study. 空前是 be，按「空前是 be 就填形容词」的口诀会填 beneficial，可空前紧挨着 of，得填名词 benefit。先查 of，这个坑就绕过去了。 convenient 的主语限制用两组对比例句并置看： The chair is comfortable.（椅子坐上去舒服，comfortable 讲身体感受） It is convenient for me to pay by phone.（付款这件事省事，convenient 讲做事的难易） convenient 作表语，主语只能是事、物、时间、地点、安排或形式主语 it。 Are you convenient? 是高频病句。问「你这周末方便吗」，得把方便落到那件事上——Is the weekend convenient for you? 或 If it is convenient for you… convenient 说的是事省不省事，comfortable 说的是身体舒不舒服。 convenient 描述一件事做起来省不省事，语义指向事件本身，人只能作 for 的宾语；comfortable 描述身体舒不舒服，语义指向感受者，所以人、椅、床都能作它的主语。 错例反着来：The Internet makes our lives more convenient. 这句成立。主语限制管的是「作表语时」的主语，作宾语补足语时补足的仍是 our lives 这件事，不指向人。 update 一家三层：update 动名同形（更新／最新消息），updated 是过去分词作定语表「被更新过的」，up-to-date 是形容词表「最新的」，最高级写 the most up-to-date；要表达「最新信息」，优先用 the latest information 或 the most up-to-date information。 抽象名词前面加修饰语，是提升表达层次最省力的一手：full use、great benefit、easy access、up-to-date information。 判定填空（第二环·便利）： Online dictionaries are of great (1)________ (benefit) to my vocabulary building, and I (2)________ (benefit) a lot from reading real examples. It is very (3)________ (convenience) for me to look up a word on my phone, and the (4)________ (update) version even marks the most up-to-date meanings. 【答案】(1) benefit　(2) benefit　(3) convenient　(4) updated 解析：第 (1) 空空前是 of，of great benefit to 填名词；第 (2) 空空后有 from，填动词 benefit，写 have benefited 亦通；第 (3) 空 very 后接形容词 convenient；第 (4) 空修饰 version 用过去分词 updated，不写 updating。 （3） 第三环·风险：链条的两端都是人 按「人伤人」这条线记，九个词自动成串，还能预判下文走向：读到「有人拿到了你的信息」，下文多半是身份被盗；读到「有人反复嘲弄同一个人」，下文多半是霸凌。 链条位置 词 判定要点 偷身份 privacy / identity / theft / steal privacy 不可数；identity theft 作整体词块，不拆拼；identity thief 指人 挑事 troll / false / rude troll 常用 several false names，无特定对象 霸凌 cyberbully / target / particular / embarrassing directed at particular people，贴 embarrassing photos 情感结果 upset / lonely / tough / stuck upset 三形合一，不写 upsetted 教材给过两个定义：troll 是 a person who posts comments or questions in order to stir up trouble online，常使用 several false names；cyberbully 是 uses the Internet to be mean to others，内容 directed at particular people，还会贴 embarrassing photos。两词都含 mean（待人刻薄）之意。 有没有特定的人——这就是 troll 与 cyberbully 的分界线。 分界不在用词狠不狠，而在对象是不是特定的某个人。四处挑事、谁撞上算谁，是 troll；认准一个人反复嘲弄，是 cyberbully。题干问「针对某个人」，落 cyberbully；问「纯粹捣乱」，落 troll。 错例：一个人先用几个假名到处挑事，后来盯住同班同学反复攻击并贴出照片。按行为落点判 cyberbully，判据是他最后有没有特定目标，与此前用什么名字无关。完形里看到 He posted rude comments under several false names 判定为 troll，是因为证据停在 several false names；同一段若再出现 the same classmate、again and again，就得改判。 privacy 是名词且不可数，private 是形容词：protect your privacy / a private chat。语法填空给 privacy 挖空，空前是形容词性物主代词或及物动词 → 名词 privacy；后面紧接名词需要修饰 → private。 identity theft 当作整体词块记，译作「身份盗窃」。教材相邻两句给了动词版和名词版：Someone might use the information to steal your identity. 与 Identity theft is a common and serious problem. 名词术语题怎么定位？回原文找它的动词定义句——「用信息做什么」，答案常就藏在同一句的上半句。 embarrassing 修饰物或事，embarrassed 修饰人，教材用的是 embarrassing photos。upset 三形合一：upset—upset—upset，形容词与动词同形，The girl was very upset / It upset her。 「被取笑」在完形里的正确项常是被动结构 be made fun of。Amy 的留言给过完整形态：A photo of her had been posted online and she was being made fun of——had been posted 是过去完成时的被动，was being made fun of 是过去进行时的被动。 stuck（困于）与 tough（艰难的）常被人塞进风险环，其实它们出自 Jan 故事：she found herself out of work and stuck at home，When you go through tough times。它们写人的处境与情感结果，不在「人伤人」链条上，单列一处记，免得在完形里把「处境艰难」读成「被人攻击」。 链条回填（第三环·风险）： Someone might use the information to (1)________ (stealing) your identity, and identity (2)________ (thief) is a common and serious problem. A photo of her had been posted online and she was being made fun (3)________ . She felt (4)________ (embarrass) and more than a little upset. 【答案】(1) steal　(2) theft　(3) of　(4) embarrassed 解析：第 (1) 空 use sth. to do 结构，填动词原形 steal；第 (2) 空 identity theft 是名词词块；第 (3) 空 make fun of 变被动后 of 留在后面；第 (4) 空修饰人用 -ed 形式 embarrassed，修饰 photos 才用 embarrassing。 （4） 第四环·对策：三条 guideline 各有触发条件 安全博客给出的 guideline 只有三条，每条都带一个触发条件，写作时照骨架换名词即可： 顺序 行动 触发条件 原句要点 一 leave the site 看到、读到让你不舒服的东西 leave the site immediately; don't post comments or click on anything 二 protect your privacy 有人索要住址、电话一类个人信息 don't give out your address or phone number 三 be polite 网上发言，不挑事不霸凌 being online is no excuse for being rude 第1条 最容易被记错。判定标准落在「你看到、读到时舒不舒服」，与对方要不要你的密码无关——If you see or read something that makes you feel uncomfortable, leave the site immediately. 这一条里同时藏着 click on 接宾语的出处：Don't post comments or click on anything. 第2条 把风险环和对策环扣在了一起：You don't want to become a target for a troll or cyberbully. 说话留分寸，就是不给别人把你当目标的理由。 三条 guideline 直接改写就是考场上的行动句： If you see or read something that makes you feel uncomfortable, leave the site at once. Never give out your personal information such as your address or phone number. Always be polite online so that you won't become a target for cyberbullies. 博客末句用的是：the more polite you are, the less likely it is you will be attacked。两个 the 后面都接比较级，后半句可倒装也可不倒装。 now that 作连词短语表「既然、由于」，引导原因状语从句，后面接既成的事实或状态；in particular 是介词短语作状语，与形容词 particular 同源，分工落在词性上。guideline 与 tip 都是可数名词，写 guidelines、tips。 charity、go through、inspire 常被挂到对策环上，其实它们属于 Jan 故事的后半段：困境（go through tough times）→ 触动（inspired）→ 行动（start a charity website）。记在 Jan 这条线上，写作时才不会串味。 词块回填（第四环·对策）： (1)________ that you have a smartphone, keep a safety rule (2)________ mind: leave the site the moment something makes you feel (3)________ (comfort). Never give (4)________ your address, (5)________ particular when a stranger asks for it. 【答案】(1) Now　(2) in　(3) uncomfortable　(4) out　(5) in 解析：第 (1) 空 Now 与 that 合成 now that，后接既成状态；第 (2) 空 keep sth. in mind 不可拆；第 (3) 空 makes you feel 后语义为「不舒服」，加前缀 un-；第 (4) 空 give out 表泄露；第 (5) 空 in particular 作状语。 4、 引导练习：先自判，后对照 下面八空先自己推，写完再对答案。 The 2026 National Cybersecurity Week ran from September 14 to 20, with its main events in Jinan. Its theme put the focus on people rather than machines. During those days, a speaker at our school said the Internet is very (1)________ (convenience), and every student should have (2)________ to it. Yet easy access also means someone might use our information to steal our (3)________ (identify). Identity (4)________ (thief) is a common and serious problem.

Anyone who finds an (4)________ (embarrass) photo of themselves online may feel upset; the more carefully we guard our personal details, the less likely we are (5)________ (become) a target for cyberbullies. 【答案】(1) has joined　(2) in　(3) updated　(4) embarrassing　(5) to become 解析：第 (1) 空 now that 后接既成事实，用现在完成时 has joined；第 (2) 空 keep sth. in mind 固定结构；第 (3) 空修饰 guide，表「被更新过的」用过去分词 updated；第 (4) 空修饰 photo，物用 -ing 形式 embarrassing；第 (5) 空 be likely to do 结构，填 to become。 7、 听力：态度与转变（附带覆盖） 本单元听力话题围绕上网活动与安全，说话人习惯先肯定便利、再转折到风险、最后给出限定性主张。只听前半句就落笔的，选中的往往正是被他反驳的那一项。 转折之后才是落点，转折之前都是铺垫。 but、however、still、to be honest 之后转向真实态度；I'd say…、The key is…、It works best when… 之后是主张所在。听力材料的结构与教材安全博客同构——先说现象，再给规则，等的就是转折那一下。 错例反着来：独白通篇没有转折词时，按首尾句与语气词判——开头给背景，结尾给总结或主张，excited、upset、worried 一类词直接透露倾向。这时死等 but，整段就空过了。 干扰项的三副面孔：绝对化（totally、too…to、everywhere）；偷换对象（把工具说成替代品、把部分说成全部、把个人的做法说成普遍要求）；时间错位（把 I used to… 里的旧做法当成现在的态度）。 听下面一段独白，回答第 1—2 题。 【朗读稿】I used to think the Internet was just for fun. I spent hours watching short videos every day. To be honest, it was exciting at first. But during this year's Cybersecurity Week in September, my teacher told us it works best when we use the Internet as a tool, not a toy. Now I set a time limit every day. I'd say the Internet is helpful, provided that we manage our time well. 1. What is the speaker's attitude towards the Internet now? A. Totally against it. B. Helpful if used properly. C. It is only a toy. 2. What does the speaker do to manage his time? A. He stops using the Internet. B. He watches videos all day. C. He sets a time limit every day. 【答案】1. B　2. C 解析：第 1 题 To be honest 后先说 exciting，But 后转到工具论，I'd say 后给出主张 helpful, provided that we manage our time well，与 B 项对应；A 含绝对化词 totally，与 helpful 冲突；C 与 use the Internet as a tool, not a toy 相反。第 2 题 Now I set a time limit every day 是既成做法，对应 C；A 与主张句矛盾，B 属 I used to 里的旧做法。 听下面一段独白，回答第 3—4 题。 【朗读稿】I used to check my phone the moment I woke up. Before I knew it, I had spent the whole morning scrolling through short videos. My mother kept telling me to spend more time outdoors, but I didn't listen. Then one day, during the Cybersecurity Week, our class did a survey on screen time. The result shocked me: I spent over six hours a day on my phone. I decided to try a technology-free evening once a week. At first it was hard, but soon I found I could read and even talk to my family again. Now I'd say the key is to make the Internet serve you, not the other way round. 3. What is the speaker's attitude towards limiting screen time? A. Helpful if done properly. B. Totally against it. C. It is only for children. 4. What made the speaker decide to change his habit? A. His mother's repeated advice. B. A survey on screen time. C. A book about technology. 【答案】3. A　4. B 解析：第 3 题 I'd say the key is to make the Internet serve you 表明他认同有节制地使用，与 A 项一致；B 与全文矛盾，C 无据。第 4 题 The result shocked me 之前的屏幕时间调查是触发点；母亲劝过但紧跟 but I didn't listen，属被否定的信息。then one day 是时间推进标记，转变题里与转折同效。 8、 课堂实战 A 档·基础过关｜语篇语法填空 阅读下面短文，在空白处填入 1 个适当的单词或括号内单词的正确形式。 In March 2026, the International Telecommunication Union reported that 2.2 billion people—more than one in four globally—remain offline, most of them in low- and middle-income countries.

Ten of the largest platforms face fines of up to 33 million dollars if they fail to take reasonable steps to block Australian users younger than 16. In July 2026, the country's internet regulator, eSafety, released a study with an uncomfortable finding: more than eight in ten under-16s are still using social media. Before the ban, nearly 86 percent of the children surveyed reported using at least one age-restricted platform; three months after it took effect, the figure was still above 81 percent. About 58 percent of teenagers said they used social media every day, compared with roughly 60 percent before. Around half of the children who kept their accounts said the platforms had not checked their age. eSafety named the platforms' failure to put in place effective age checks as the main reason. The government says the rule is about protecting children from cyberbullying and harmful content. Reddit, one of the ten platforms, has challenged the ban in the High Court while continuing to follow it. 1. What did the eSafety study in July 2026 find? A. The ban has removed most teenage accounts. B. Teenagers have stopped using social media at school. C. Most under-16s are still using social media. D. Platforms have checked every user's age. 【答案】C 解析：more than eight in ten under-16s are still using social media 与 C 项同义；A 与数据相反；B 无据；D 与 around half…had not checked their age 冲突。 2. Why could many children keep their accounts according to eSafety? A. Their parents helped them hide their age. B. The government cancelled the fines. C. They moved to video game platforms. D. The platforms failed to check ages effectively. 【答案】D 解析：eSafety named the platforms' failure to put in place effective age checks as the main reason，与 D 项一致；A、C 把个别做法当成普遍原因，B 与罚款条款矛盾。 3. What can be inferred from the numbers in the passage? A. Daily use has changed little since the ban. B. More teens started using social media after the ban. C. Age checks have become stricter over time. D. Half of the children deleted their accounts. 【答案】A 解析：58 percent 与 roughly 60 percent 几乎持平，说明日常使用变化极小；B 与数据下降方向相反；C 与「未核验年龄」冲突；D 偷换对象，half 指的是保留了账号的孩子。 4. What is the writer's attitude towards the effect of the ban? A. Uninterested. B. Fully supportive. C. Totally against it. D. Doubtful about it. 【答案】D 解析：an uncomfortable finding 与 still above 81 percent 表明作者对其效果存疑；A 与全文不符；B 与数据冲突；C 含绝对化词 totally，作者并未全盘否定禁令本身。 C 档·冲刺挑战｜完形填空 阅读下面短文，从每题所给的 A、B、C、D 四个选项中选出可以填入空白处的最佳选项。 Last winter, a girl in our class received a voice message from "her father". The voice sounded exactly like his, and the message said he was in trouble and needed money at once. She was about to send it when her mother called. That call saved the family a lot of money. In March 2026, INTERPOL and the UN Office on Drugs and Crime warned that generative AI tools had made it much easier for criminals to (1)______ trusted people. A familiar voice or face can support a story, (2)______ it cannot prove who is really asking. The US Internet Crime Complaint Center said in July 2026 that scammers had even used AI-generated videos of a senior official to (3)______ earlier victims towards a copied website. What makes these tricks work is not the technology (4)______. Details (5)______ from social profiles and old conversations help the story fit the person being (6)______.

The reason is simple: rudeness attracts the wrong kind of attention. A person who posts comments just to stir up trouble is called a troll; such a person often hides behind several false names and picks on whoever passes by. A cyberbully works differently. The meanness is directed at particular people, again and again, sometimes with embarrassing photos posted for everyone to see. The line between the two is drawn by one thing: whether there is a chosen target. These habits protect the person who keeps them as much as the person they are aimed at—rudeness makes you a target, too. The blog's last line puts it neatly: the more polite you are, the less likely it is you will be attacked. 1. What does the underlined word "meanness" most probably mean? A. 耐心 B. 善良 C. 幽默 D. 刻薄 【答案】D 解析：meanness 与 directed at particular people、embarrassing photos 同现，语义落在「待人刻薄」；A、B、C 与霸凌语境相拗。 2. How is a cyberbully different from a troll? A. A cyberbully uses several false names. B. A cyberbully aims at a particular person. C. A cyberbully writes longer comments. D. A cyberbully picks on whoever passes by. 【答案】B 解析：directed at particular people 是 cyberbully 的定义特征；A、D 是 troll 的行为（several false names、whoever passes by），C 无据。 3. What can be inferred from Paragraph 2? A. Politeness online protects both sides. B. Teachers' advice is usually empty. C. Photos should never be posted online. D. Classmates laugh at others face to face. 【答案】A 解析：These habits protect the person who keeps them as much as the person they are aimed at 表明礼貌同时保护双方；B 与 can sound empty 冲突；C 把「不转发」说成「永不发布」，属绝对化；D 无据。 4. Which of the following is the best title for the passage? A. How to Post Photos Online B. Why Trolls Use False Names C. Politeness as a Safety Rule Online D. The History of Online Rudeness 【答案】C 解析：全文把礼貌与隐私保护并列为安全规则，末句以 the more…the less likely… 收束，C 项涵盖主旨；A、B 只取局部，D 未涉及。 9、 课堂小结 四环速记：连接靠 surf，便利归 convenient；风险的施动者是人，identity theft 排第一；对策按教材顺序——先走（leave the site）、再捂（protect your privacy）、后客气（be polite）。 词形判定的总开关只有一个：先看空后，再查空前。空后的 from、of、宾语能当场定词性；空前的 have、can、easy、very 在三步之后再起作用。 收尾自测（五空）： My grandma used to think the Internet was for young people only. Now she (1)________ (surf) it every morning and has easy (2)________ to opera videos. She says it is (3)________ (convenience) to learn a new recipe on her phone. What worries me is different: a stranger once asked her for her address, and someone like that might use it to steal her (4)________ . So we agreed on one rule—keep it (5)________ mind: never give out personal information, and leave the site the moment something makes her uncomfortable. 【答案】(1) surfs　(2) access　(3) convenient　(4) identity　(5) in 解析：第 (1) 空 every morning 提示一般现在时，主语单数填 surfs；第 (2) 空 easy 后接名词 access；第 (3) 空 very 式修饰，填形容词 convenient；第 (4) 空 steal one's identity 固定搭配；第 (5) 空 keep sth. in mind 固定结构。五空串起四环，一空一环。 10、 课后巩固 - 本页为独立作业，用时约 30 分钟。 （1） 语法填空 阅读下面短文，在空白处填入 1 个适当的单词或括号内单词的正确形式。 The 2026 National Cybersecurity Week was held from September 14 to 20, with its opening ceremony in Jinan, Shandong.

To close such gaps, ITU and UNICEF run an initiative called Giga, which has mapped connectivity in over 2.2 million schools in more than 40 countries and has helped connect tens of thousands of schools. Another programme, Partner2Connect, has gathered more than 82 billion dollars in pledges to support meaningful connectivity in developing countries. For students, the meaning of these numbers is concrete. A school with a connection can offer online lessons, digital libraries and safe search tools; a school without one cannot. Teachers in connected schools report that students who once walked miles for a reference book now keep track of the latest information on a shared screen. Connectivity alone will not do, though. Young people also need the skills to tell a reliable source from a copied one, and the habits to protect their privacy while online. That is why ITU has joined an AI Skills Coalition with partners across the United Nations, the private sector and universities. 1. What does the initiative Giga do? A. It builds new schools in 40 countries. B. It trains teachers to use AI tools. C. It maps school connectivity and helps connect schools. D. It sells devices to low-income families. 【答案】C 解析：has mapped connectivity in over 2.2 million schools…and has helped connect tens of thousands of schools 与 C 项完全对应；A 把「绘制联网地图」说成「建学校」，属偷换对象；B、D 无据。 2. How much has Partner2Connect gathered in pledges? A. 8.2 billion dollars. B. 82 billion dollars. C. 2.2 billion dollars. D. 820 million dollars. 【答案】B 解析：more than 82 billion dollars in pledges，选 B；A、D 是数字错位，C 是离线人口数，属偷换数据。 3. What does the last paragraph suggest about connectivity? A. It has closed the digital divide completely. B. It matters less than buying new devices. C. It should replace classroom teaching. D. It works only together with skills and safe habits. 【答案】D 解析：Connectivity alone will not do 与 need the skills、the habits 表明联网需与技能、习惯配合；A 与 still offline 冲突，B、C 无据且含绝对化意味。 4. What is the writer's attitude towards connecting schools? A. Supportive, yet not content with connection alone. B. Doubtful about its value. C. Totally against it. D. Uninterested in the numbers. 【答案】A 解析：全文肯定联网带来的变化，末段又用 will not do 指出光有连接不够，态度是支持而不满足；B、D 与全文基调相反，C 含绝对化词 totally。 （3） 完形填空 阅读下面短文，从每题所给的 A、B、C、D 四个选项中选出可以填入空白处的最佳选项。 Last month our school called for volunteers for a community book drive. I signed up on the official website, which was quite (1)______: I filled in a form, created an (2)______ and waited for a confirmation email. The email arrived the next morning. It looked real, with the school's name on top, and it asked me to (3)______ my personal details by following a link. I was about to (4)______ it when I remembered the Cybersecurity Week poster in our hallway: never click on a (5)______ link in an email. Instead, I opened the official app and checked my (6)______ there. The real message said no further action was needed. The email in my inbox was a (7)______ for my information. Had I followed the link, a stranger could have got my address and phone number and used them to steal my (8)______. I reported it to the website and told my classmates in our group chat. Two of them had received the (9)______ email. One said she felt (10)______ when she realised how close she had been to giving out her details. Now (11)______ we all know the trick, we have agreed on three habits: read the sender's address carefully; (12)______ any request through the official app rather than through the email; and keep our personal details (13)______. I also (14)______ my password that week and turned on an extra safety check. The experience did not make me (15)______ the Internet.

B 解析：第 1 空 convenient 与语境一致。第 2 空 created an account 创建账户。第 3 空 update my personal details 更新个人信息。第 4 空 was about to click on it 与后文 never click on a strange link 对应。第 5 空 strange link 是风险所在。第 6 空在官方 app 里查看 messages。第 7 空 trap 表陷阱，与 looked real 形成反差。第 8 空 steal my identity 属「人伤人」链条。第 9 空 the same email 表明同学收到同一封邮件。第 10 空差点泄露信息的感受是 upset。第 11 空 Now 与空位合成 now that。第 12 空 confirm any request 核实请求。第 13 空 private 作补足语。第 14 空 updated my password 用过去式。第 15 空 leave the Internet 与末句构成转折收束。 （4） 应用文写作 你校英文网站正在开展主题为 "Safe Online, Smart Online" 的帖子征集活动。假定你是李华，请写一篇短帖投稿，内容包括： 1. 简述一次你或你同学遇到的网络风险； 2. 给出至少两条自护做法，须用上 protect your privacy、leave the site、become a target for 中的至少两个； 3. 提醒同学：网络风险的施动者是人。 要求：1. 词数 80 左右；2. 可适当增加细节，以使行文连贯。 开头已给出：Recently, a stranger asked me for my address online, which really upset me. 【参考范文】Recently, a stranger asked me for my address online, which really upset me. I refused at once and reported it to the website. That experience shows online risks come from people more often than from viruses. Here are two rules I follow now: protect your privacy—never give out your address or phone number, since a stranger might use them to steal your identity; and if anything makes you feel uncomfortable, leave the site immediately. Being polite online helps too, because rudeness can make you a target for cyberbullies.（正文 88 词） 学科网周周有招-高中英语同步系列尖子班精品讲义 学科网（北京）股份有限公司 $
