Question

What’s so great about exercise? Even though the thought of jogging, jumping rope, or getting hot and dirty makes you unhappy, there are ways that working out can still be fun. You might enjoy a game like volleyball, or maybe you ride your bicycle with friends. You could also get moving by walking your dog. These are all ways to work out, or exercise.

Exercise is a must in order to keep healthy. It makes your body stronger, gives you more energy, and even makes you feel happier.

When you exercise, you use your muscles(肌肉). This makes them stronger including muscles deep inside the body, such as your heart. The job of the heart muscle is to send blood(血液) throughout the body. A strong heart gets the job done much easier. It certainly is important to strengthen that muscle.

When you exercise, you feel like you have more energy. Energy is the power to move around. A healthy body does not have to work as hard to move, and it does not get tired as quickly.

Another advantage of exercise is that it makes you feel good. Exercise causes the body to produce a kind of chemical(化学物质) in the brain(大脑) that calms you, and raises your spirits too. This chemical change makes you feel good, just like the good feelings you get from being stronger and having more energy.

Eating right is another way to stay healthy. Breakfast is very important if you make it a healthy one. It gives power to your body and to your brain. It’s easier to choose healthy foods if you know what you need. Children generally need about a cup and a half of fruit and a cup and a half of vegetables every day. You should drink between four and eight glasses of water and juice each day.

The final ingredient(因素) for good health is to get enough rest. Growing children need about nine hours of sleep every night. When the body is asleep, it repairs(修复) itself.

The body is like a machine. If you take good care of it, it can work well for a long time.
