四、阅读理解
As a teenager, you are becoming more independent (独立的) and making decisions for yourself. Being a teenager can be challenging, but it can also be exciting. You are also learning to take risks and work out problems better. And changes are happening throughout your body, even in your brain (头脑).
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 places. When you were a child, as you learnt new things, your brain created more and more roads to different places. 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 useful.
As a result, your experiences as a teenager actually influence the way that your brain develops. If you spend hours playing video games, you learn to see something with your eyes and respond (回应) 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 (有效率的). So, your video-game playing could be preparing you for a career such as a pilot (飞行员).
This is a great time for you to practise 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 developing your brain for the future.
