Have you ever shown your photos on your favorite social media? 【小题1】 If yes, do you know what you have posted on the social media can cause problems you could not expect?

Many teenagers think they know everything about social media, and that bad things could never happen to them. However, studies show that each year more than three million young people in the world get into trouble because of their online activities.

So do remember these if you really want to share something online.

【小题2】 Not everyone will like what you write online. Think before you post anything. You never know who sees your texts, pictures or videos. Before clicking “post”, you should ask yourself, “How will I feel if my family or teachers see this?” and “How might this post be bad for me in five or ten years from now?”

【小题3】 Imagine someone is unfriendly in real life. The same is true of online communication. 【小题4】 If you feel angry or frustrated while you’re writing a message, wait a bit. Read it again later and then send it.
