A. 阅读短文，完成下列各题。
Now many kids and teenagers use social media every day. To protect young people, many countries make strict social media rules from 2025. Some people agree with these rules, but others don't.
In 2025, Australia makes a law. It stops kids under 16 from using social media. It is the first country with this rule. In January 2026, France passes a new rule. It will ban(禁止) kids under 15 from using social media from September 2026. Denmark plans to make the same rule for kids under 15 in 2026. Malaysia will stop kids under 16 from using social media alone in 2026. They can use it only with their parents.
Some people think the rules are helpful. Social media may bring online bullying(霸凌) and harmful information. Kids may be addicted(上瘾的) to screens. The rules can keep kids safe. They help kids focus on study and outdoor activities. But some people do not think full bans are good. The rules take away kids' chances to learn online and talk with their friends. It is hard for apps to check users' ages, too.
China does not have a full ban. But it has rules to protect minors online. China asks apps to use a minor mode(模式). This mode limits(限制) kids' screen time and stops bad content. Schools help kids form good online habits, too.
