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.

A computer can get very hot when it works on a lot of programs. It can cost a lot to cool the computer. So some scientists want to know what would happen when if the heat from the computer could be used.
Large Internet companies such as Google and Microsoft have thousands of computers. As these computers deal with information, they produce lots of heat, so they need huge cooling systems. These systems send the heat into the air.
A company in the Netherlands thinks paying to make the computers work and then paying again to cool them are a waste of energy. So the company developed a special device—the e-Radiator.
Boaz Leupe, head of the company, says that e-Radiator works as a heating system and saves money. He explains that the energy is used twice—once to heat the home and once to cool the computer and that the users don't have to pay to cool their computers.
Five homeowners in the Netherlands are testing the heating system in their homes.
"We pay for the computer usage, so in that way, homeowners get heating for free." Boaz says.
Jan Visser is one of the homeowners. "If you use the computer more, the e-Radiator produces more heat," he says. "It cannot provide enough heat if you don't use your computer often." But he is ready to try it. It's a great help to his family.
The company says e-Radiators produce heat temperature of up to 55℃. It says the system could save its users about $ 440 a year.
1.Which of the following is true?
A.Before the e-Radiator appears, the heat of a computer is usually sent into the air.
B.Google and Microsoft don't need huge cooling systems.
C.Google and Microsoft developed a special device-the e-Radiator.
D.The heat of a computer usually makes the computer work better before the e-Radiator appears.
2.What is the e-Radiator mainly used to do?
A.To help Google B.To provide heat. C.To heat the computer. D.To clean the computer.
3.How much could the system save its users a month?
A.About 220 dollars. B.About 440 dollars. C.About 44 dollars D.About 36 dollars.
4.What would be the best title for the passage?
A.A New Company B.How to Heat Computers
C.A New Way to Heat Homes D.How to Solve Environment Problems
