My name is Jack. I am eleven. I don't like to exercise but I like to play. I really like to play basketball. Yesterday my mom told me that I had to exercise. I told her, "No!" Then, I went out to play soccer with my friend, Sam. After playing soccer we jumped high. Then we rode our bikes. Finally I came home for dinner. After I washed my hands, my mom said, "Thanks for exercising. What was she talking about? I didn't exercise. I just played with a friend!  Right? In fact. I did both. My active playtime with Sam has been great exercise at the same time.

Exercising does not have to be boring. Some people think that you can only exercise at a gym. That is not true (真的). Running after a flying ball, and playing soccer with your friends are both great ways to exercise. Why not jump? You could also ride your bike. These are all great ways to exercise, too.

Please remember exercise is really just another word for "active fun"! So find a friend, choose a sport to play, and get going. You'll be so busy having a good time, and you'll forget that you are exercising.

In order to be healthy, you should stay at a healthy weight(体重). So, how do you keep a healthy weight? You need to eat a balanced diet (平衡的饮食). You need to balance your eating with exercise.

What is a balanced diet? A balanced diet includes all the main food groups. These include fruits and vegetables. Grains found in bread, noodles, and rice are also important. You need foods such as milk and cheese. You also need to eat foods that have protein( 蛋白质), such as meat, eggs, fish, and some beans.

Wow, that's a lot of food! How many calories is that? How many should you have in a day? Most teens need at least 2, 000 calories a day. That sounds like a lot. But you are forgetting the other part of the balance. You need to exercise. Exercise burns (燃烧)calories. If you burn off as many calories as you take in, you will stay at the same weight. If you eat more calories than you burn, you will put on weight.

To keep your weight, eat a balanced diet and exercise more. And if it's your birthday, eat a piece of cake. Once in a while, it won't hurt you!

Vaccines (疫苗) help keep you healthy. How do vaccines help you keep healthy? The vaccines are made from bacteria (细菌)that causes the illness. A little bit of bacteria isn't enough to make you sick. But it is enough to make your immune system(免疫系统) active.

While some vaccines are a lifetime, others wear off after a few months or years. Most doctors suggest the following vaccines: measles-mumps-rubella, hepatitis B and chicken pox. After these vaccines when you are very young, you will be far away from most of these diseases all your life.

Joe's flu vaccine will be good for about six months to a year. His doctor explained why. "When I give a flu shot(注射), "Dr. Smith said, "I put a bit of flu bacteria into your body. You build up antibodies(抗体) against this bacteria. But this vaccine won't protect you once (一旦) the bacteria has changed. That's why you will have to get a new one before the flu season hits next year."

"I had the flu last year," Joe said. "I was really sick. I missed a whole week of school. When I did go back, I still didn't feel really great. I couldn't even play basketball for another week after that. I guess it's worth (值得…的) getting a flu shot every year. "

Are you protected? That shot is so much easier than getting one of these serious illnesses.
