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.

“How are you?” is a nice question. It’s a friendly greeting that people in the United States use. However, “How are you?” is also an unusual question. It’s a question that often doesn’t need an answer. The person who asks, “How are you?” expects to hear the answer “Fine,” even if the person isn’t fine. The reason is that “How are you?” isn’t really a question and “Fine” isn’t really an answer. They are common ways of saying “hello” or “hi”.

Sometimes, people don’t say exactly what they mean. For example, when someone asks “Do you agree?” the other person may be thinking, “No, I don’t. I think you’re wrong.” It isn’t polite to disagree very strongly, so he might say, “I am not so sure.” This is a nicer way to say that you don’t agree with someone.

People also don’t say exactly what they are thinking when they finish talking to other people. For example, many conversations over the phone end when one person says, “I’ve got to go now,” or the person who wants to hang up gives an excuse such as “Someone is at the door,” or, “Something is burning on the stove.” The excuse may be real, or not. The person who wants to hang up simply doesn’t want to talk any more, but it isn’t polite to say so. An excuse is polite, and it doesn’t hurt the other person’s feelings.

Whether they are greeting each other, talking about an opinion, or ending a conversation, people often don’t say exactly what they are thinking. This is one way of being nice to people, and it’s a part of the game of language.
