There is no doubt that digital technology allows us to learn and communicate more easily. For example, during the pandemic, I took online classes and video chatted with my friends. That was really helpful. However, digital life also has disadvantages. I sometimes spend too much time on my phone, and it takes up my study time. My eyes also get tired. So I believe we should use digital devices wisely. Don’t let them control your life. 1 学科网（北京）股份有限公司 $
