Why Is Exercise Cool?

1．Exercise Strengthens Muscles

Did you ever do a push-up or swing across the monkey bars at the Playground. 【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.

2． 【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．

3．Exercise Keeps the Balance

【3】Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic stuff. 【4】If you're not very active, your body won't need as many calories.

Whatever your calorie need , 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.

4．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. 【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.

Answer 1

【答案】

【1】D

【2】E

【3】B

【4】G

【5】C

【解析】

【1】D 本段的标题是Exercise Strengthens Muscles锻炼能够强壮我们的肌肉，横线前句Did you ever do a push-up or swing across the monkey bars at the Playground中提到的push-up引体向上等都是锻炼力量的锻炼项目。故D项Those are exercises that can build strength.符合上下文。

【2】E 根据本段中心句最后一句Being flexible is having full range of motion, which means you can move your arms and legs freely without feeling tightness or pain．可知灵活性意味着可以毫不痛苦地移动增加的胳膊和腿。也就是说锻炼还可以增强我们的灵活性。故E正确。

【3】B 本句的标题是Exercise Keeps the Balance锻炼能够让我们保持平衡。横线后句Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic stuff.身体需要一定的能量，那么这些能量从哪里来。应该是从我们摄入的食物中来，所以B项：Food gives your body fuel in the form of calories, which are a kind of energy.符合上下文串联。

【4】G 根据横线下句If you're not very active, your body won't need as many calories.如果你不积极锻炼，那么你的身体就不再需要如此多的能量。与之相对应的是G项：But if you're active, your body needs an extra measure of calories or energy.如果我们积极锻炼，我们的身体就需要更多的能量。故G项与上下文一致。

【5】C 根据前一句But you may not know that exercising can actually put you in a better mood.我们不知道的是锻炼能够让我们处于更好的精神状态中，也就是说锻炼能提高我们的情绪。C项：When you exercise, your brain releases a chemical, which may make you feel happier.是解释具体原因。
