(2017·合肥市第一次教学质量检测) You're growing up.That means you're probably experiencing lots of changes，all at once.Your body is changing.It might even seem as if your entire self is changing.It can be confusing and even scary. 1 And it's good!
Growing up means that you can do more，learn more，and start to make your mark on the world.In order for that to happen, your body produces chemicals called hormones that help both body and mind grow.Hormone levels change constantly，rising and falling. 2 But it's partly to blame for intense emotions，surprising reactions，and mood swings.
Because of the way your brain develops，it is somewhat ruled by emotions now and through your teen years.As a result, growing up can seem like an emotional roller coaster！ 3
●Take care of yourself.If you eat right，sleep enough，and get good exercise，your brain will be much more able to deal with the stress.
● 4 When you feel your moods swinging or you're upset，or confused，some quiet time will allow you to gather your thoughts and get calmer.
●Practice relaxing your body and deep breathing when you wake up and when you go to bed. 5 Plus，when stuff happens during the day，you'll be able to calm yourself quickly with a deep breath or two before you react.Your body is changing.

【语篇解读】 本文是一篇说明文。主要介绍了青少年如何应对成长过程中的一些变化。
1．B [由空前的“confusing and even scary”和空后的“good”可知，空处在这里起承上启下的作用，所以选B项。]
2．D [由空前一句可知，荷尔蒙的水平一直在不断地改变，忽高忽低；D项中的“This changing”与空前的“change”相对应，所以选D项。]
3．F [空前的“an emotional roller coaster”与F项中的“make the ride smoother”相对应，且由下文列举的几个要点可知，F项符合文意。]
4．A [由本段中的“一些安静的时间将使你集中精神，安静下来”可知，A项正确。]
5．E [空前的“Practice relaxing your body and deep breathing”与E项中的“It”对应，空前的“when you wake up”与E项的“start the morning right”对应；空前的“when you go to bed”与E项的“fall asleep”对应。所以选E项。]
