The Internet: A Super Highway in Light
We can think of the internet as a super-fast highway. But instead 21 cars, it carries information. This highway isn’t made of asphalt (沥青)—it 22 as pulses of light (脉冲光) through cables (电缆) under the ground or even under the ocean.
How does your message reach a friend far away It’s like sending a package. First, your device (装置) makes your words or pictures into a “package”. Then, it needs 23 address. That’s what an IP address is—a unique (独一无二的) string of numbers that tells 24 the package should go.
Next, a “delivery (快递) person” called a router (路由器) 25 with the delivery. The router reads the address and decides the 26 way to send the package, just like a mail carrier choosing a route. 27 your phone or laptop is connected to Wi-Fi, the package can travel through the air to the router—no cables needed.
Wi-Fi is like a magic bridge in your home. It lets your devices talk to the router without cables
28 . So you can sit on the sofa and still send a 29 . But remember, this magic bridge has limits—if you stay too far from the router, the signal will get weak, like a voice fading away.
Your message is traveling on a highway of light, with IP addresses as maps and routers as helpful guides, connecting people across the world in 30 . So next time you send a message, think about this amazing journey, smile.
( ) 21. A. of B. for C. out
( ) 22. A. travel B. traveled C. travels
( ) 23. A. a B. an C. the
( ) 24. A. who B. where C. which
( ) 25. A. helps B. helped C. will help
( ) 26. A. good B. better C. best
( ) 27. A. If B. But C. Though
( ) 28. A. less quickly B. quickly C. most quickly
( ) 29. A. message B. messages C. messages’
( ) 30. A. second B. seconds C. second’s

Think of 33 as a strict but caring doorman of a busy building. Every time you open a webpage or send a message, data (数据) tries to enter or leave your device. I check it 34 . I follow a list of rules set by your parents or the computer system (系统). These rules tell me what’s allowed and what’s not. If something looks dangerous, such as a virus hiding in a file (文件) or a
35 from an unknown source (来源), I stop it right away, just like a doorman would stop someone with a bad intention (意图).
I don’t just say “no” to trouble, I also let good things 36 quickly: the funny videos you want to watch, the homework files your teacher sends, or the messages from your friends. It’s a balancing act—keeping 37 out without slowing down the things you need to do.
Sometimes you might 38 why you can’t load a webpage or download a file. That’s probably because I am doing my job. I 39 everything harmful trying to rush into your computer.

阅读下面四篇语言材料，然后按文后要求做题。
A
Do you have online classes Nowadays, many students take classes at home. All you need is a computer and a headset（头戴式耳机）. Here are some opinions about online classes from three students.
Li Lan is a 15-year-old student from Beijing. “There are no real teachers watching me. I can surf the internet or do other things if I want to. It’s hard to always listen to them carefully all the time,” she says. Li Lan tries to prepare a lot before class to make sure she will pay attention. She also tries to talk more with teachers online. But she still finds it difficult to stay focused.
Li Wen is a 14-year-old student from Chengdu. She thinks online interaction (互动) isn’t enough. “The online teachers don’t really get to know me. And I don’t know them well either. If I don’t hand in homework, all I get is a short message instead of real concern,” she says.
Wang Qiang, 16 years old, comes from Shanghai. “It saves time and money compared to taking offline classes. Also, if I don’t understand some parts of a lesson, I can watch that part of the lesson again,” he says.

Algorithms (算法) on our computers and phones are like helpful guides. They show us videos, articles, or songs we might enjoy, but they also probably keep us inside a small world with only the things we already like. For teenagers, it is important to step out of these algorithm-made circles and try to learn things from different fields.
Think about this: if you only watch sports videos, you might miss amazing science experiments or beautiful poems that could open your mind to different ideas. Algorithms keep suggesting similar content based on your clicks, but that does not mean you have to stay in that loop (圈). You can choose to search for a history fact after watching a music video, or read a story about nature even if math is your favorite subject.
Doing this helps you develop critical thinking—knowing what is worth your time and what is not. It is like being a gardener: instead of letting the algorithm plant the same flower again and again, you pick seeds (种子) from different gardens to create your own colorful garden.
So when your phone shows you the similar things, take a small step to explore something different. Click on something new. Algorithms are tools, not cages (笼), and your curiosity should be the key to explore more.
根据材料内容选择最佳答案。
( ) 46. What do algorithms act like according to the text
A. Strict parents. B. Helpful guides.
C. Dangerous traps. D. Silent teachers.
( ) 47. If Kangkang click some videos about movies on his phone, what will the algorithms
continue to suggest
A. Different kinds of movies.
B. Amazing science experiments.
C. Music videos of famous singers.
D. Beautiful poems from all over the world.
( ) 48. What is the gardener in the text trying to do
A. Plant the same flower again and again.
B. Let the algorithm choose all the seeds.
C. Pick seeds from different gardens to grow a colorful garden.
D. Water the flowers every day.
( ) 49. What is the main idea of this text
A. Algorithms are dangerous and should be avoided.
B. Teenagers should use algorithms to only watch their favorite things.
C. It is important to use your curiosity to explore beyond what algorithms suggest.
D. Sports videos are not as good as science experiments.
( ) 50. Which of the following would the author most likely agree with
A. It’s best to let the algorithm decide everything for you.
B. Clicking on new and different things is a waste of time.
C. Your curiosity is the key to learning new and different things.
D. A colorful garden is the best reward for using your phone.
C
It was 11:45 p.m. 16-year-old Lin was still awake. Suddenly, a message popped up on her phone. It was from someone she didn’t know: “I’m lost in the mountains. My phone is almost dead, and I can’t call for help. Please, can you do something ” The message came with a fuzzy (模糊的) picture of a trail (小径), sent through a hiking app.
Lin didn’t hesitate (犹豫). She saved the picture and sent it to a local rescue (救援) group’s online chat. “This person is lost here,” she wrote. “Her phone is dying—does anyone know where this is ”
In less than two minutes, a rescue worker replied, “That looks like Green Hill Trail. There’s no phone signal there. We can send a team, but we need more clues (线索).” Lin messaged the lost hiker right away, asking her to describe (描述) her surroundings. “A big rock with a small tree next to it,” she answered. “Battery (电池) at 2%.”
Lin passed the information to the rescue worker, who said, “We’re sending a team now. Try to keep her talking if possible.” Lin typed back quickly, asking about the weather and how she felt, just to keep the connection alive. At 12:20 a.m., the rescue worker sent a short message, “We found her. She is okay. Thanks for your help.”
Lin smiled, putting her mind at ease. On a quiet night, a simple phone and a few messages had turned a terrible situation into a safe one. The internet, which can sometimes feel far away, had been like a lifeline.

The metaverse (元宇宙) is a virtual (虚拟的) world where people meet and do things online with technology. It’s not just for playing games or talking. It’s also important for countries because it brings good chances and some problems that need rules to control them. 56
For countries, the metaverse offers big opportunities (机遇). It can develop the growth of new industries, like online education or virtual shops, creating more jobs and making economies stronger.
57 For example, people from all over the world can learn about a country’s history or art in fun and new ways through the metaverse.
But there are challenges too. 58 There’s also a risk of data (数据) being stolen (偷走的) or unfair rules that hurt a country’s interests. For example, if people in a country lose money to fake virtual land deals, it could harm that country’s economy.
59 They should make clear rules to protect everyone. They should also help their own tech companies do well, so they can stay competitive (竞争的). This way, the metaverse can help all countries, turning its chances into real progress.
60 With care and teamwork, it can benefit all countries, not just a few.
根据材料内容，从下面七个选项中选出五个能填入文中空缺处的最佳答案，使文章意思通顺、内容完整，并将选项填入下列横线上。
A. But they have disadvantages. B. It’s true that every coin has two sides. C. It also allows countries to share their culture with the world easily. D. The metaverse is new, but it affects the world a lot. E. To keep the metaverse safe and fair, countries need to work together. F. Because of the metaverse, many teenagers waste too much time online instead of studying. G. If one country controls too much of the metaverse, others may have less power.

Umbrella for Teens’ Online Safety
The internet is a big, busy place where teens chat, learn, and share. However, it also hides
61 (risk)—so we need to build an umbrella to keep them safe.
For example, 62 using an app, never share your account password with others, even your close friends. If someone 63 (steal) it, they could pretend (假装) to be you and send hurtful messages that hurt others. If someone sends a video that makes you 64 (comfort), don’t respond (回答). Press “report” instead, because reply could bring 65 (many) trouble.
One of the worst 66 (danger) is that some teens might face hate comments (评论) online. These comments may make you feel sad or afraid, but remember: those words say more about the sender 67 you. Talk to a parent or teacher, and they’ll help you deal with it.
To stay safe, set rules for 68 (you). Don’t click on strange links, think carefully before
69 (post) photos, try spending less time on apps that make you feel unhappy. Schools and families can work together too—teaching teens how to recognize (识别) dangers online and where to get help.
The internet should be a place for fun and growth, not fear. With care and smart choices, we can hold up 70 umbrella, keeping teens safe while they explore all the good things online. Let’s do it together.

Using Mobile Phones Wisely
Mobile phones are very important in our life. We can easily call others, search for information and even make payments in seconds. However, they also have disadvantages. So we should use them wisely.
First, don’t use them for meaningless things. Playing games and watching short videos are just ways to relax, so don’t spend too much time on them.
Second, don’t look at the screen for too long, especially before sleeping. It is very bad for your eyes and will make you feel tired next day.
Also, remember to put your phone down when communicating with family. Don’t let it harm your close relationships.
Of course, I can’t list all the problems and ways to solve them here. But if we use mobile phones carefully and wisely, they will help us a lot instead of causing problems!
