Question

【题目】 Being a teenager can be challenging, but it can also be exciting. You’re becoming more independent and making decisions for yourself. You are also learning to take risks and solve problems better. And changes are happening throughout your body, even in your brain.

The changes in your brain are influencing how you develop into an adult. Imagine the structure（结构）of your brain is like a big road map. Lots of roads lead to different destinations(目的地）. When you were a child, as you learnt new things, your brain created more and more roads to different destinations. By the time you become a teenager, many different roads lead to the most important places on the map. Now your brain’s job is to make that map more efficient.

As a result, your experiences as a teenager actually influence the way that your brain develops. If you spend hours playing video games, what skills do you use? You learn to see something with your eyes and respond to it with your hands. As you develop those skills, your brain is making sure that the roads leading to them are especially fast and efficient. So, your video—game playing could be preparing you for a career such as a pilot.

This is a great time for you to practice new skills and discover what you’re good at and try what you love doing. Go out and try different activities, and stick to them if you think they’re useful. Remember that with everything you do, you’re shaping your brain for the future.
