【题目】 You are walking alone down the street. Suddenly, you hear footsteps. Is someone following you? How do you know the footsteps are someone else’s and not your own?

You can tell because your brain has the ability to ignore certain sounds, according to a study from New York University. Because of this, we often ignore our own footsteps. But we may easily hear others’ footsteps.

Scientists tested this on mice. They found that when mice became familiar with the sound of their own footsteps, they developed a “sensory filter (感觉过滤器)”, according to David Schneider, one of the lead authors of the study. This allowed the mice to ignore the sounds of their own footsteps. They could more easily notice the sounds of their environment.

“For mice, this is really important,” Schneider told Science Daily. “They need to listen for a cat getting close to them, even when they’re walking and making noise.”

Our brains don’t just ignore our footsteps. We also ignore some other sounds that we make ourselves, including the sound of eating, breathing heavily and typing on a keyboard. Being able to ignore these unimportant noises lets us focus on more important and dangerous ones. For example, we are quick to notice the sound of a baby crying. So we can rush to make sure they are okay and keep them alive. The same idea applies to humans screaming. When we hear this sound, we can quickly go to help the screaming person.

【题目】Model Railroading

Would you like to know a fun way to learn about math? Well, you can do that with model railroading. Yes, it’s true. You can learn about many school topics without using a school book. Besides that, there are many other benefits that model railroading brings us as well. In this article, we will discuss just a few of those benefits of model railroading.

Patience and problem solving skills

When you build a model railroad, you have to plan your railroad out. You have to decide where the tracks (轨道) will go, where to put buildings, where to put streets and any other things you would like to add to your model railroad. Also, you have to think about any problems you may have with the design you choose. How will you make railroad crossings? How will you design hills, mountains, and rivers? Deciding on what to do with your model railroad takes a lot of thought and patience, but it is not as difficult as you may think.

Building skills

With model railroading, you learn how to put together plastic models of buildings. Also, you can learn how to build a table for your design, or make scenery for the geography of your design. Your model railroad runs on electricity, so you learn about electronics as well. These are skills that not only help you build a model railroad; these skills will help you all throughout life.

Fun for family and friends

Different from many video games, model railroading is a social hobby that lets you communicate with family and friends. This is because you have to communicate with family and friends as you build and run your model railroad. By spending time with the people in your life you love and care about, you learn to become closer and care more for each other. This is one of the best parts of model railroading as a hobby. Of course, the best part about model railroading is running the trains. Watching the trains run around the track and make all the sounds and do all the things that real trains do gives people hours of enjoyment. Also, there is great satisfaction in the fact that you, your family, and your friends built the model railroad.

I hope you can learn to enjoy model railroading and experience all the benefits you just read about and many others. Happy railroading!
