Why Is Exercise Cool?
Exercise strengthens Muscles
Did you ever do a push-up or swing across the monkey bars at the playground? 小题1:  By using your muscles to do powerful things, you can make them stronger. For older teens and adults, this kind of workout can make muscles bigger, too.
小题2:  
Can you touch your toes easily without yelling ouch? Most kids are pretty flexible, which means that they can bend and stretch their bodies without much trouble. Being flexible is having “full range of motion” , which means you can move your arms and legs freely without feeling tightness or pain.
Exercise Keeps the Balance
小题3:  Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic stuff. 小题4:  If you’re not very active, your body won’t need as many calories. Whatever your calorie need is, if you eat enough to meet that need, your body weight will stay about the same. If you eat more calories than your body needs, it may be stored as extra fat.
Exercise Makes You Feel Good
It feels good to have a strong, flexible body that can do all the activities you enjoy---like running, jumping, and playing with your friends. It’s also fun to be good at something, like scoring a basket, hitting a home run, or perfecting a dive.
But you may not know that exercising can actually put you in a better mood.小题5:  It’s just another reason why exercise is cool!

A．So you want to do some aerobic(有氧的) exercise right now?

B．Food gives your body fuel in the form of calories, which are a kind of energy.

C．When you exercise, your brain releases a chemical, which may make you feel happier.

D．Those are exercises that can build strength.

E. Exercise Makes You Flexible
F. Exercise Makes Your Heart Happy
G. But if you’re active, your body needs an extra measure of calories or energy.

试题分析：本文叙述了为什么锻炼是酷的？一是锻炼能够锻炼肌肉。二是锻炼能使身体有柔韧性。三是锻炼能使身体保持平衡。四是锻炼能使人感觉心情好。短文从以上四个方面进行了阐述。
小题1:根据Did you ever do a push-up or swing across the monkey bars at the playground?By using your muscles to do powerful things, you can make them stronger. 根据上下文可知应选D。
小题2:根据Can you touch your toes easily without yelling ouch? Most kids are pretty flexible 锻炼能使身体灵活，故选E。
小题3:根据Your body needs a certain amount of calories every day just to function,食物能给人一定的热量，故选B。
小题4:根据If you’re not very active, your body won’t need as many calories. 可知，如果你是爱运动的，你的身体需要一个额外的热量或能量。故选G。
小题5:根据But you may not know that exercising can actually put you in a better mood.可知应选C。
