Should kids have smartphones? Some may agree while others may not. Recently, we had a class meeting and talked about the topic.

Some students explain why kids should have smartphones. First, phones allow parents to get in touch with their kids easily. Parents can see their kids’ location and pick them up if there’s a sudden dangerous event or situation. Second is education. An app like Duolingo helps kids learn Spanish and other languages. Bilibili can also be a learning tool when it’s used appropriately(恰当地). Finally, smartphones help kids communicate with their friends, especially when they are in different cities or countries.

Here are also reasons why kids should not own smartphones. Looking at screens for too long could be bad for their eyes. Smartphones can also take away students’ attention from school. And studies say that teenagers and young adults who spend the most time on social-media platforms(社交媒体平台) are more often feeling sad and hopeless than those who spend the least time on them. This might happen to kids, too. What about safety? Well, children should always be with adults, so safety is not a reason for using a smartphone. With all the risks to health, schoolwork, and happiness, it’s not worth it for kids to have smartphones.

As for me, I advise not taking any risks. Young kids are not good at controlling their smartphone use. The more time kids are on their phones, the more they can be exposed to strangers, bullying(欺凌), and other dangers. Not to mention the effects on their health, including anxiety and sleep problems.
