Digital shock
1 I’ve studied in China for a year and now it’s the Christmas holiday. I’ve been back in the UK for three days, but it feels like a century! It’s amazing to see my family. Also, I really love Christmas and the delicious food. However, I’ve had some digital problems here.
2 Today, I wanted to get some vegetables and meat from a shop. I decided to ride a shared bike to get there. But it took forever to find a bike! I finally found an old one. But that 20-minute ride cost me an arm and a leg – 4.8 pounds!
3 In the shop, I quickly got everything I needed. I wanted to pay with my smartphone. I asked the shopkeeper to show the QR code, but she didn’t understand! Next, I tried to use my digital wallet, but the shop’s payment system didn’t work. The shopkeeper told me to use cash. As I always make digital payments in China, I never carry my wallet. I had to go home to get some cash.
4 When I got home, I was so tired that I gave up on cooking. I ordered my favourite dishes through an app instead, but the delivery was really slow. When my dishes finally arrived 90 minutes later, they were stone-cold! I had to heat them one by one in the oven. I felt tired and hungry.
5 Except for today, I’ve had a great holiday. However, I’m looking forward to going back to China. The technology there lets me live a more convenient life!
数字冲击
1 我在中国留学一年，现在圣诞假期回到英国，回家三天却像过了一个世纪。见到家人很开心，我也十分期待圣诞美食，但这里的数字生活处处让我不习惯。
2 今天我想去超市买菜，打算骑共享单车过去，可找车找了超级久。好不容易找到一辆旧车，短短 20 分钟路程花了我 4.8 英镑，贵得离谱！
3 进超市买好食材，我想用手机扫码付款，让店员出示二维码，她完全不懂。我又尝试数字钱包，店里支付系统无法使用。店员让我付现金，可在中国我一直手机支付，从不带钱包，只能回家取钱。
4 到家我累得不想做饭，就在软件点外卖，配送慢得离谱，90 分钟才送到，饭菜已经凉透。我只能放进烤箱逐个加热，又累又饿。
5 除了今天这件糟心事，假期整体不错。但我无比期待回到中国，那里的数字科技让生活便利太多！
重要课文 2
The fun they had ( Isaac Asimov )
1 In her diary, on 17 May 2157, Margie wrote: “Today, Tommy found a real book!”
2 It was a very old book. They turned the old, yellow pages. It was strange to read the words. They stood still on the pages, instead of moving across a screen.
3 “What a waste!” said Tommy. “When you finish the book, you just throw it away, I guess. Our television screen must have a million books on it! I wouldn’t throw it away.”
4 Margie asked, “What’s the book about?”
5 “School.”
6 “Why would anyone write about school?”
7 “Because it’s an old kind of school, from hundreds of years ago. They had a teacher, but it was a person. There was a special building, and all the kids and teachers went there.”
8 Margie wanted to read about those funny schools. But her mother called, “Margie! School!”
9 Margie’s classroom was right next to her bedroom. Her teacher was a machine. It was on and waiting for her. The screen was lit up. The machine said: “Today’s lesson is on maths. Please put yesterday’s homework in the opening.”
10 Margie did so sadly. She was thinking about the old schools. All the kids from the neighbourhood came, and laughed and shouted in the playground. They sat together in the classroom, and went home together after school.
11 And the teachers were people…
12 Margie was thinking about how the students must have loved school in the old days. She was thinking about the fun they had.
他们曾经拥有的快乐（艾萨克・阿西莫夫）
1 2157 年 5 月 17 日，玛吉在日记中写道：“今天汤米找到了一本真正的纸质书！”
2 书页泛黄老旧，文字静止印在纸上，不像屏幕上滚动的文字，读起来十分新奇。
3 “太浪费了！” 汤米说，“看完就要丢掉，我们电视屏幕能存上百万本书，永远不用扔。”
4 玛吉问书写的是什么。
5 “学校。”
6 “怎么会有人写学校？”
7 “这是几百年前老式学校。那时老师是真人，大家集中到一栋建筑里上课。”
8 玛吉很想读这本书，可妈妈喊她上课。
9 玛吉的教室就在卧室隔壁，老师是一台机器，机器已经启动，正等着她使用。屏幕亮起：“今日数学课，请把昨日作业放入投递口。”
10 玛吉闷闷照做，心里向往旧式校园：邻里孩子一同上学，在操场嬉笑打闹，同坐一间教室，放学结伴回家。
11 老师都是活生生的人……
12 玛吉暗自猜想，从前的孩子们一定无比热爱校园，拥有无数欢乐时光。

语法1-不定式作宾语补足语
1. 定义：动词不定式（to do 或 do）作宾语补足语时，主要用于补充说明宾语的动作、状态或特征，使句子语义完整。
2. 结构：不定式与宾语形成逻辑上的主谓关系，即宾语是不定式动作的执行者。
① 肯定形式：主语 + 谓语动词 + 宾语 + to do/do（有些情况to可省略）
② 否定形式：主语 + 谓语动词 + 宾语 + not to do（直接在to前加not）
3. 带 to 的不定式（to do）作宾语补足语
① 表“意愿、命令、要求、请求”类动词：ask（要求）、tell（告诉）、want（想要）、wish（希望）、order（命令）、require（要求）、teach（教）、invite（邀请）、encourage（鼓励）等。
例句：
The teacher asks us to finish the homework.
老师要求我们完成作业。
③表“认知、判断、意见”类动词：believe（相信）、consider（认为）、think（认为）、find（发现）、suppose（料想）等，常为 to be + 名词/形容词，to be 有时可省略。
例句：④ 表“情感、心理”类动词：like（喜欢）、hate（讨厌）、prefer（偏爱）、expect（期望）等。
例句：⑤ 表“使、让”类动词（get）：注意：get 后必须带 to，与 let/make 不同。
例句：⑥ 表“成语动词”类：call on（号召）、arrange for（安排）等。
例句：4. 不带 to 的不定式（do）作宾语补足语
① 感官动词类（一感二听五看）：feel（感觉）、hear（听见）、listen to（听）、see（看见）、watch（观看）、notice（注意到）、observe（观察）等，强调感知到宾语动作的“全过程”或“一次性动作”。
例句：
I saw him cross the street.
我看见他过马路了。
② 使役动词类（三使）：let（让）、make（使）、have（使、让），强调“让/使/迫使”宾语做某事，后接不带to的不定式，但被动语态需恢复to。
例句：
She made me cry.（主动语态无to）
她让我哭了。
I was made to apologize.（被动语态加to）
我被迫道歉。
③ 半帮助类（help 帮助）
例句：
I helped my grandma (to) carry the box.
我帮奶奶搬箱子。
语法2-as引导的各类从句（扩展）
1. as 引导原因状语从句：as 引导原因，语气比 because 弱，侧重显而易见、双方都知道的理由，常放句首，表 “因为、由于”。
①As + 从句，主句
As I have a phone, I seldom take cash.
因为我有手机，我很少带现金。
②主句 + as + 从句
I don’t play games as I have much homework.
我不玩游戏，因为我作业很多。
2. as 引导时间状语从句：有两层含义，表示 “当…… 时；随着”。
①当…… 的时候（= when，强调同步发生）
As she was reading, her mum came in.
她看书的时候，妈妈进来了。
②随着（伴随变化）
As you grow older, you will know more.
随着你长大，你会懂得更多。
3. as 引导同级比较状语从句（as…as…）
①肯定：A+动词+as+原级 (adj./adv.) +as+B，表示“和…… 一样”
Online shopping is as convenient as going to shops.
网购和实体店购物一样方便。
②否定：A+动词+not as/so+原级+as+B，表示“不如......”
This app is not so useful as that one.
这个软件不如那个好用。
备注：中间必须用形容词 / 副词原级，不能用比较级、最高级。
4. as 引导方式状语从句：表示“按照…… 的方式”；“像…… 那样”；“如同”。
①Do as I told you.
照我说的做。
②You should behave online as you do in real life.
你上网举止要和现实中一样。
5. 固定复合连词 as 引导从句
①as soon as 一…… 就……（时间状语从句，主句一般将来时/从句一般现在时）
I will call you as soon as I get home.
我一到家就给你打电话。
②as long as 只要（条件状语从句）

只要保护隐私，你就可以上网。
③as if /as though 好像（方式状语从句）

1. somewhere：在某处，到某处（肯定句）

网上没有地方能隐藏你的个人信息。

我找那款软件，可到处都找不到。
2. 统一规则
①这四个副词的前面不加介词 in /to/at
❌ go to somewhere
✅ go somewhere
②修饰词后置：形容词 / 不定式放后面
somewhere quiet 安静的地方
somewhere to relax 可以放松的地方

英文范文
例文1：
My digital life
Now we are living in a fast-developing digital age. My digital life has become an indispensable part of my daily study and life. Digital technology greatly changes our living ways and brings us many surprises.
I have a smartphone and I use various useful apps every day. I often search for learning materials online to improve my study. I also take online courses and share my creative works on the Internet in my spare time. These digital tools make my study more efficient and my life more convenient and colorful.
However, every coin has two sides. Staring at electronic screens for a long time is harmful to my eyesight and may influence my study. To avoid these problems, I decide to use digital products wisely and strictly control my online time. I will let digital technology serve me better.
翻译：
我的数字生活
如今我们生活在飞速发展的数字时代，数字生活已然成为我日常学习和生活中不可或缺的一部分，数字科技极大地改变了我们的生活方式，为我们带来了诸多惊喜。
我拥有一部智能手机，每天都会使用各类实用的应用程序。我经常上网查阅学习资料来提升学业，课余时间还会参与网课学习，在网上分享自己的创意作品。这些数字化工具让我的学习更高效，生活也变得便捷多彩。
但凡事皆有利弊，长时间盯着电子屏幕会损害视力，还可能影响学习。为规避这些问题，我会理智使用数码产品，严格控制上网时长，让数字科技更好地为我所用。
例文2：
AI Changes Our Life
Nowadays, artificial intelligence is changing the world quickly and becoming an important part of our daily life.
AI brings us plenty of advantages. It makes our life more convenient and efficient. We can use AI to search for useful information, finish study tasks and solve different problems. It also helps people work better and saves lots of time. With the development of AI, our society is making great progress.
However, every coin has two sides. If people depend on AI too much, they may become lazy and lose the ability to think independently.
In my opinion, we should make good use of AI. It is a good helper if we use it wisely. We should let AI serve us instead of controlling us.
翻译：
人工智能改变我们的生活
如今，人工智能正在快速改变世界，成为我们日常生活的重要组成部分。
人工智能为我们带来了许多优势。它让我们的生活更加便捷高效。我们可以利用人工智能查阅资料、完成学习任务、解决各类难题。它也帮助人们更好地工作，节省大量时间。随着人工智能的发展，社会取得了巨大进步。
但凡事有利有弊。如果人们过度依赖人工智能，就会变得懒惰，失去独立思考的能力。
在我看来，我们应当好好利用人工智能。只要理性使用，它就是我们的好帮手。我们要让人工智能为我们服务，而不是被它支配。
