B
The internet lets everyone share their ideas, seemingly creating a more open and colourful world. However, have you ever felt like you're in your own small world? Everything you hear or see just makes you more sure of what you already think.
In fact, most people are now in what is called an “echo chamber(回音室)”—also known as an information cocoon(信息茧房)—a place where your own ideas keep coming back to you, and you don't hear any different ones. This isn't anything new and it's happening a lot more now.
Echo chambers are like “rooms” on the internet where everyone agrees with you. Think about how people used to sit around a fire, telling stories that made everyone else all nod and smile. The internet is our modern - day fire.
Social media platforms know exactly what we like. That's thanks to very smart algorithms(算法). These algorithms watch what we do on the internet to show us more information that matches our interests.
Being in an echo chamber makes us feel good. However, this can make our opinions and thinking very rigid(僵化的) and make it hard for us to understand people who think differently.
Luckily, there are ways to break free from echo chambers. One big step is to challenge ourselves by looking for information from different sources(来源). Also, ask questions about where the information you've found comes from, double - check facts and be open - minded.
