Part 2 Dear Mum and Dad, could you teach me more about online safety? I think it is important because I use the internet for school and games.

If we believe false information, we might make bad decisions or share lies. Being careful helps us avoid scams and stay informed. Always ask yourself: who wrote this and why? 1 学科网（北京）股份有限公司 $
