1. (2023高二上·天津市开学考)  听下面一段对话，回答问题。 

Richard, I need to work out teenagers' use of social media. Can you answer a few questions?<br />Sure.<br />First, I have to put your answers in the correct age category. So, you are obviously in the<br />15 to 16 group rather than the 13 to 14 or 17 to 19 groups.<br />That's right.<br />So, Richard, how much time do you spend using social media?<br />About two hours every day. I spend most of the time sending messages.<br />Sometimes, I comment on friends' posts or post photos online.<br />Do you make new friends through social media?<br />Never. There's without a doubt a risk involved.<br />Well, my friend had a negative experience and I think we should be more careful about<br />using social networking to make friends.<br />Richard, I need to work out teenagers' use of social media.
