第515篇红婵学霸清华北大学霸笔记长难句三

长难句三：We ought to set reasonable limits for our online time. Make clear distinction between study use and entertainment use of digital devices.

固定搭配make a distinction between区分；set limits for给……设置限度。

译文：我们应当给自己上网时间设立合理限度，分清数字设备用于学习和用于娱乐的界限。

仿写句子：We should make a clear distinction between virtual excitement and real‑life happiness.我们要分清虚拟的快感和现实生活的幸福。

长难句四：We cannot reject the progress of the times, but we must keep control over ourselves. Make digital tools serve our growth, instead of letting ourselves become slaves to screens.

keep control over掌控；make sb do使某人做某事，不带to；instead of介词短语，后接doing。

译文：我们不能拒绝时代的进步，但我们必须掌控自我。让数字工具服务我们的成长，而不是让我们自己沦为屏幕的奴隶。

语法提醒：make用于被动语态时要还原to：be made to do。

整篇课文长难句解析完毕，红婵儿梳理本单元核心语法：情态动词综合复盘。

情态动词本身不能单独作谓语，后面接动词原形，没有人称数的变化；高考高频考点：can/could, may/might, must/have to, shall/should, need, dare；情态动词+have done表对过去推测。

1.can / could：能够，可以；could可表委婉请求，过去能力。

We can use digital devices to collect learning resources.我们可以使用数字设备搜集学习资源。

Could you please tell me how to improve digital literacy?你能否告诉我如何提升数字素养？

2.may / might：可能，可以；might可能性更低。

The information online may be false.网上的信息有可能是假的。

3.must：必须；肯定推测；mustn’t禁止。have to客观不得不。

We must learn to protect our personal privacy online.我们必须学会在网上保护个人隐私。

You mustn’t spread unconfirmed news.你严禁传播未经证实的消息。

4.should：应该，劝告建议。

We should keep balance between online and real‑life life.我们应当平衡线上与现实生活。

5.情态动词+have done（对过去事情推测）

must have done过去一定做过；may/might have done过去可能做过；

can’t/couldn’t have done过去不可能做过；should have done本应该做（实际没做）。

You should have set a time limit for your screen time.你本应该给自己的屏幕使用时间设置限制。

高频易错红笔记录：

①must表推测只用于肯定句；否定推测“不可能”用can’t。

②mustn’t表禁止；表“不必”用needn’t / don’t have to。

③should have done本该做却没做；shouldn’t have done本不该做却做了，改错高频。

④情态动词后面一律接动词原形，不能加to（除have to）。

先贤的思绪缓缓飘散开来。

情态动词表达人的主观态度、劝告、约束。面对数字生活，我们要有清醒自我约束，知道什么该做，什么不该做，拥有把控自己行为的力量。

语法要点梳理完毕，红婵儿转入书面表达专项训练。本单元写作任务议论文：Be the master of digital life做数字生活的主人，分析网络利弊，指出青少年现存问题，阐述数字素养内涵，呼吁理性使用网络，做工具的主人而非奴隶。

搭建完整行文框架。

开篇：数字时代网络深刻改变青少年生活，网络带来便利资源，同时潜藏诸多风险，不少同学陷入沉迷网络的困境。

主体第一段：辩证分析，网络本身无好坏，批判两种极端态度：全盘追捧网络、完全排斥科技都不可取。列举青少年常见问题：沉迷娱乐、难辨虚假信息、隐私泄露、网络不文明行为。

Be the master of digital life

Now digital technology has stepped into every corner of our daily life. Smart phones and the Internet offer teenagers convenient learning channels and rich information. Especially for us rural students, the Internet breaks geographical barriers and provides us with plenty of learning materials we could hardly get before. However, digital life also brings serious challenges. Many teenagers fail to keep balance between online activities and real‑world life. Some get addicted to games and short videos, wasting masses of valuable study time. Besides, mixed online information may mislead young people, and risks of privacy exposure and online violence cannot be ignored.

Digital technology itself is neither good nor bad. It is only a tool. Yet two wrong attitudes are popular among teenagers. Some regard the online world as everything, blindly believing all information shown on screens. Others refuse digital devices completely and reject the advantages of modern technology. Neither way is sensible. What we need is good digital literacy.

To become masters of digital life, we should do several things well. First, manage our screen time strictly. Draw a clear line between study use and entertainment use of digital devices. Never let online entertainment take up time which belongs to study, sports and face‑to‑face communication. Second, develop critical thinking. Before believing or forwarding online messages, judge whether the information source is reliable. Learn to distinguish true facts from false rumours and never spread unconfirmed content. Third, protect personal privacy and behave politely online. We should remember that the Internet is not a rule‑free area.

We rural students can make full use of online learning resources to fill our knowledge gaps. At the same time, we must not escape real‑life difficulties by hiding in the virtual world. Real friendship, family warmth and personal progress can never be replaced by online pleasure.

Technology should serve our growth. Do not become slaves to your screen. Let us improve our digital literacy and be the true masters of digital life.

亮点批注：step into every corner踏入每一个角落；break geographical barriers打破地域壁垒；masses of大量；draw a clear line划清界限；fill knowledge gaps填补知识漏洞；rule‑free area无规则地带。

誊写完范文之后红婵儿自主改写一篇短文，变换措辞锻炼灵活表达的能力。

Be the master of digital life

In modern society, digital products play an important role in teenagers’ daily life. We can search learning resources, attend online courses and communicate with distant friends through the Internet. Nevertheless, a lot of teenagers suffer from problems caused by improper use of digital devices. They spend too much time on online entertainment, which harms their study and physical health. What is more, false information online may mislead teenagers who lack judgement.

We ought to understand that the Internet is just a tool. Its influence depends on users. It is wrong to worship everything online, and it is also unwise to reject digital progress totally. We need to build up our digital literacy so that we can make good use of online resources and stay away from hidden risks.

There are practical steps for us students to follow. We should set proper time limits for using phones. Separate study time from entertainment time. We need to think critically when facing online information and refuse to pass on doubtful news. Meanwhile, keep our private information safe and keep good manners while surfing the Internet.

For us students from the countryside, the Internet opens a window to the outside world. We should value this chance to improve ourselves. But we must keep in mind that virtual excitement cannot take the place of real‑life experience.

We should not be controlled by our digital devices. Let us be self‑disciplined and be masters of our own digital life.

对照两篇文稿，红婵儿记下心得。科技类议论文一定要辩证看待利弊，不要全盘否定网络；重点掌握情态动词用法，must表推测只用肯定句，否定推测用can’t；情态动词+have done是语法填空高频；get addicted to中to是介词，后接doing，极易写错。写作多用while引导让步状语，增强句式层次感。

笔记推进至错题复盘板块，把随堂练习之中出错的题目完整记录下来，标注出错缘由。

错题一语法填空：Some teenagers get addicted to ______(play) short‑videos.

to是介词，填playing。红婵儿误填play。批注be/get addicted to中to为介词，后接doing。

错题二单项选择：The news on the Internet ______ be false; you can’t believe it completely.

A.must B.may C.should D.need

表“有可能”，选B。错选A。批注must肯定推测，语气过于绝对，网络消息只是有可能虚假。

错题三语法填空：You ______ (should) have wasted so much time on games; you ought to focus on study.

本不该做却做了，shouldn’t have done，填shouldn’t。红婵儿误填should。

错题四改错：You mustn’t to finish all work in one day; you can do it step by step.

must情态动词后接动词原形，去掉to。

整理完错题，红婵儿放下笔望向窗外。天边暮色沉沉，农家灯火次第亮起，不少人家屋内亮着手机屏幕。网络给乡村少年推开一扇看向大千世界的窗子，可这扇窗子也藏着诱惑与陷阱。做完这一单元笔记，红婵儿心中更加清醒：网络工具本身无罪，自律才是第一道防线。善用它汲取知识拓宽眼界，却不沉溺屏幕虚幻欢愉，分清虚拟与现实，做数字生活的主人。厚厚的学霸笔记一页页堆叠，英语带给她的不只是试卷分数，更教会她理性看待时代浪潮，守住自我本心。

先贤的意念慢慢消散在暮色光影之间，留下思绪落在纸页：科技是得力仆人，却是危险主人。善用工具，约束自我，莫让屏幕掌控你的人生。

红婵儿拿起笔，在笔记末尾写下独属于自己的感悟。

本单元掌握数字生活主题词汇，重点复盘情态动词以及情态动词+have done的用法；牢记get addicted to中介词to后接doing；must表推测仅用于肯定句，否定
