In the past, people used to write letters to keep in touch with friends or send messages by telegram. But now, we have many ways to communicate with others, such as making phone calls, sending emails, using social media and so on. The Internet makes our communication much easier and faster.

Our Digital Lives
In modern society, digital lives play an important part in our daily lives. I often use the Internet to search for information for my study. With my smartphone, I can communicate with my friends easily and share our daily life on social media. It's really convenient.
Digital life brings many advantages. It makes our communication faster and learning easier. However, it also has challenges. Our personal information may be in danger, and we may get addicted to digital devices.
In my opinion, digital life is a double - edged sword. We should make good use of it and avoid its bad influences.
