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 本段的標題是Exercise Strengthens Muscles鍛煉能夠強壯我們的肌肉，橫線前句Did you ever do a push-up or swing across the monkey bars at the Playground中提到的push-up引體向上等都是鍛煉力量的鍛煉項目。故D項Those are exercises that can build strength.符合上下文。

【2】E 根據(jù)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．可知靈活性意味著可以毫不痛苦地移動增加的胳膊和腿。也就是說鍛煉還可以增強我們的靈活性。故E正確。

【3】B 本句的標題是Exercise Keeps the Balance鍛煉能夠讓我們保持平衡。橫線后句Your body needs a certain amount of calories every day just to function, breathe, walk around, and do all the basic stuff.身體需要一定的能量，那么這些能量從哪里來。應(yīng)該是從我們攝入的食物中來，所以B項：Food gives your body fuel in the form of calories, which are a kind of energy.符合上下文串聯(lián)。

【4】G 根據(jù)橫線下句If you're not very active, your body won't need as many calories.如果你不積極鍛煉，那么你的身體就不再需要如此多的能量。與之相對應(yīng)的是G項：But if you're active, your body needs an extra measure of calories or energy.如果我們積極鍛煉，我們的身體就需要更多的能量。故G項與上下文一致。

【5】C 根據(jù)前一句But you may not know that exercising can actually put you in a better mood.我們不知道的是鍛煉能夠讓我們處于更好的精神狀態(tài)中，也就是說鍛煉能提高我們的情緒。C項：When you exercise, your brain releases a chemical, which may make you feel happier.是解釋具體原因。
