It's about using technology responsibly, respectfully, and safely. Here are some guidelines: Protect Yourself and Others: Never share passwords, addresses, or phone numbers online. Be careful about what photos you post. Think about how your online actions might affect others. Never participate in or encourage cyberbullying. Respect Intellectual Property: Don't copy other people's work (like essays, art, or music) and pretend it's yours. It's okay to use information from the internet for school projects, but you must say where it came from. Think Critically: Not everything online is true. Check facts before you believe or share information. Be aware that some people might try to trick you online. Balance Your Time: Make sure you have time for offline activities like sports, reading, and spending time with family and friends. Don't let screens take over your life.

VII. 任务型阅读。阅读下面短文，回答问题。 My name is Li Wei, and I want to share a lesson I learned about digital responsibility. Last year, I joined a new online game. I made a friend in the game called "SuperStar". We chatted a lot and became close online friends. He was very friendly and often gave me tips to win the game. One day, he asked me for my phone number, saying he wanted to chat faster and send me some cool game cheats. I was excited and almost gave it to him. But then I remembered what my teacher had said in our digital safety class: "Never share personal information with strangers online, no matter how friendly they seem." I felt confused. "SuperStar" seemed like a real friend. I decided to talk to my older brother about it. My brother said, "It's great you have online friends, but you don't really know who they are. Someone could pretend to be a kid but be an adult with bad intentions. It's not safe to give out your number." I listened to my brother. I told "SuperStar" that I wasn't comfortable sharing my number but was happy to keep chatting in the game. He seemed okay with it at first, but then he stopped talking to me. A few weeks later, I heard from another player that "SuperStar" had been banned from the game for trying to scam people. I was shocked and very glad I hadn't shared my number. This experience taught me that being cautious online is very important. Real friends will respect your boundaries. 1. Where did Li Wei make a friend called "SuperStar"? 2. What did "SuperStar" ask Li Wei for? 3. What did Li Wei's teacher say about sharing information online? 4. Who did Li Wei talk to about this problem? 5.
