"过去，人们将照片视为记忆的记录。重点在于过去时态。随着Instagram的出现，重点在于现在时态。"

Simplified Meaning:

In earlier times, people used photos to remember important moments and events that happened before. They would look at photos to recall memories from the past, like looking at old family albums to celebrate birthdays or weddings. Photos were like a treasure chest of old memories, bringing back what happened many years ago. Today, platforms like Instagram change how we think about photos. Instead of just saving old memories, we use Instagram to share what’s happening right now, as it happens. For example, if you're at a fun concert or enjoying a delicious meal, you might snap a picture and post it immediately. This way, your friends can see and experience that moment with you almost instantly. It's about sharing your current experiences and staying connected with others in real-time, making the present more engaging and interactive. Instead of just preserving the past, it lets us enjoy and share the present moment with others.
