    Being a teenager can be challenging, but it can also be exciting. 1. You are also learning to take risks and solve problems better.

Changes are happening throughout your body, even in your brain. 2. Imagine the structure of your brain is like a big road map. Lots of roads lead to different destinations. When you were a child as you learnt new things, your brain created more and more roads to different destinations. 3. Now your brain makes 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? 4. As you develop those skills, your brain is making sure that the roads leading to them are especially fast and efficient.

This is a great time for you to practice new skills and discover what you are good at and what you love most. 5. Remember that with everything you do, you’re shaping your brain for the future.

A.The changes in your brain are influencing how you develop into an adult.

B.Playing cards with your mind can make your memory better.

C.You’re becoming more and more independent and making decisions for yourself.

D.So try different activities, and stick to them if you think they’re useful.

E.By the time you become a teenager, many different roads lead to the most important places on the map.

F.You learn to see something with your eyes and respond to it with your hands.

G.Different people have different change in the body.

    WHAT are scientists? They are often described as gray-haired white-coated dull scholars.

But the world has changed. Young scientists are making their voices heard and releasing their powers on the world stage.

This is also true in China. Rising stars include new materials expert Gong Yongji, university professor Liu Mingzhen, and biologist Wang Ruixue. At the age of 28 in 2018, Wan Ruixue received the 2018 Science & SciLifeLab Prize for Young Scientists. This is a global prize to reward outstanding scientists at an early stage of their careers.

She focuses mainly on biomedicine(生物医学)and artificial intelligence(人工智能). "Both are cutting-edge(前沿)technologies at an early stage of development," she said.

"So, I think they have great potential to be developed. I think in the study of cutting-edge technologies, China and other leading countries in the world are standing on the same starting line. And in the study of structural biology, China is likely to become the leader."

She felt it was her fate to become a biologist. "I grew interested in the natural world, when I was very young," she said. In 2009, she entered Sun Yat-sen University.

In her third year at the university, she realized that she wanted to do something related to biomedicine. So she emailed China's top biologist Shi Yigong, hoping to join his lab at Tsinghua University.

Shi recognized her talent and welcomed her. Years of efforts at the lab have paid off. Her research on the high-definition 3D structure of spliceosome led to a scientific breakthrough.

Unlike-many of other young scientists who choose to pursue further study abroad, Wan currently has no plan to go overseas.

"The whole ecosystem for scientific research is continually improving in China," she said, adding the country has great science facilities.
