【解析】

本文是一篇说明文。主要讲述青少年时期的经历影响大脑的发育。

1.根据下一句“You are also learning to take risks and solve problems better.”（你也在学习承担风险，更好地解决问题。）此句中的also提示上文应该是并列结构，C选项“You’re becoming more and more independent and making decisions for yourself.”（你变得越来越独立，自己做决定。）同下一句呼应，C选项切题。

2.根据前一句“Changes are happening throughout your body, even in your brain.”（变化正在你的全身发生，甚至在你的大脑里。）下一句接着写大脑发生的变化，是顺承关系。A选项“The changes in your brain are influencing how you develop into an adult.”（你大脑中的变化会影响你如何成长为一个成年人。），故A选项切题。

3.空格前一句为“When you were a child as you learnt new things, your brain created more and more roads to different destinations.”（当你还是个孩子的时候，你学习新事物的时候，你的大脑会创造出越来越多通往不同目的地的道路。），再根据空格下一句“Now your brain makes that map more efficient.”（现在你的大脑使这个地图更有效率。），空中要起到承上启下的作用，根据文章，随着青少年经历的增长，大脑应该发生更多的变化。E选项“By the time you become a teenager, many different roads lead to the most important places on the map.”（当你成为一个青少年的时候，许多不同的道路通向地图上最重要的地方。），E选项切题。

4.根据空前一句“If you spend hours playing video games, what skills do you use?”（如果你长时间玩电子游戏，你会用到什么技能?），空中用来回答此提问，F选项“You learn to see something with your eyes and respond to it with your hands.”（你学会用眼睛看东西，然后用手回应。）正好回答上文问题，F选项切题。

5.根据空前一句“This is a great time for you to practice new skills and discover what you are good at and what you love most.”（这是你练习新的技能，发现你擅长什么和你最喜欢什么的最佳时间。）D选项“So try different activities, and stick to them if you think they’re useful.”（所以尝试不同的活动，如果你觉得有用就坚持下去。），前一句为学习新技能的最佳时间，所以这时应该尝试不同活动，两句构成因果关系，D选项切题。
