However, it also hides 1 (risk)—so we need to build an umbrella to keep them safe. For example, 2 using an app, never share your account password with others, even your close friends. If someone 3 (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 4 (comfort), don’t respond (回答). Press “report” instead, because reply could bring 5 (many) trouble. One of the worst 6 (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 7 you. Talk to a parent or teacher, and they’ll help you deal with it. To stay safe, set rules for 8 (you). Don’t click on strange links, think carefully before 9 (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 10 umbrella, keeping teens safe while they explore all the good things online.

That’s what an IP address is—a unique (独一无二的) string of numbers that tells 4 the package should go. Next, a “delivery (快递) person” called a router (路由器) 5 with the delivery. The router reads the address and decides the 6 way to send the package, just like a mail carrier choosing a route. 7 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 8 . So you can sit on the sofa and still send a 9 . 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 10 . So next time you send a message, think about this amazing journey, smile. 1. A. of B. for C. out 2. A. travel B. traveled C. travels 3. A. a B. an C. the 4. A. who B. where C. which 5.

Think of 3 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 4 . 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 5 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 6 quickly: the funny videos you want to watch, the homework files your teacher sends, or the messages from your friends.
