Why Is Exercise Cool?

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.  

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

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 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.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.

Zoos divide opinion ： there are those who think it is cruel to keep animals locked up while others believe zoos are essential for the survival of endangered species.

To argue that zoos imprison animals is to misunderstand what zoos are about. Without zoos many of the creatures we love and admire would no longer exist. Every single day，over one hundred animal species vanish. Scientists predict that as early as 2050 one quarter of the Earth’s species will become extinct.

Some animals are in danger because they are hunted. Alarmingly, the population of tigers has already fallen by ninety-five percent. Other species are in danger because of a lack of food. For example, there are fewer than 1300 giant pandas left in the wild.

Zoos have special breeding programmes to help those animals at risk. These breeding programmes are proving extremely successful. As Irene Shapiro from Zoo and Wildlife Support says, “the Puerto Rican Parrot has grown in numbers from just thirteen to about eighty-five and the Golden Lion Tamarin Monkey, which has almost ceased to exist twenty years ago, has been reintroduced back into the wild. ”

Unfortunately, not everyone understands this important role zoos play. For example, Brian Featherstone from the Anti-Zoo Forum says, “I can’t believe we take animals from the wild and put them in cages for the entertainment of the public! We should view them on film or TV in their natural environment.，’

However, this misses the point. A zoo does more than display animals to the public. It ensures their survival. Without zoos you would not be able to see many of these animals on TV or anywhere else!
