题目 08 范文：支持 A（社交媒体具有积极影响）
I agree with Kelly that social media can have a positive influence on public opinion. It gives ordinary people a way to share experiences that large news organizations may overlook. A local problem, such as unsafe drinking water, can gain national attention after residents post clear evidence online. Social media also helps charities and community groups find volunteers quickly. Paul is right that users sometimes see only views they already agree with, but people can follow several reliable sources and read different opinions. Schools should also teach students how to check online information. When users act responsibly, social media makes public discussion more open and allows important voices to be heard.
