How to Become Fit?
Healthy eating habit along with regular exercise is the only way to become fit. If you have the correct number of calories and exercise regularly, you will lose weight, keep fit, and feel great, too.
During your teenage years, it is important to give your body the energy it needs. If you skip (跳过) meals, you won’t get enough calories, and then you will feel tired. By the way, calorie is just another word for energy. About 50% of your calories should come from rice, bread, vegetables and fruit. You also need to drink a lot of water, 6 to 8 glasses a day. Water helps keep your system clean. Drinking enough water will make your skin better and make you healthy.
Exercise is something that can help to make you look good, feel good and be healthy. Experts suggest that teenagers spend at least 30 minutes exercising, five times a week. That is easy to do! You can walk or ride your bike to school, and do sports at school. However, teenagers often give up sports, saying they have no time left after their studies. In fact, doing exercise can help them sleep better at night and increase their ability to focus on their study.
If you follow the suggestions above, you will look and feel much better and become fit.
【小题1】 What’s the main idea of this passage?

“Teenager” means a person from 13 to 19 years old. Although they’re young, they have to make many important choices by themselves. Often teachers and parents cannot handle them because they don’t understand and know teenagers, especially their wishes, problems or different moods in a short time. They need to think about questions like these: Should we go to college? What kind of job do I want? However, other people also influence their choices. Who influences teenagers?

It depends on the kind of choice. When teenagers buy things, friends are the most important influence. This is especially true for clothes and music. TV shows, advertisements and parents also influence teenagers. In more serious things, parents are probably the most important influence. Some teenagers say it’s best to regard both parents and friends as influences. James, a seventeen-year-old boy says he’s “just a crazy man”. He also says, “Parents are really important because they can tell you what’s right and wrong.”

But teenagers also feel they need to make choices—to make their own mistakes. As one teenager girl said, “If our parents don’t let us make our own choices, maybe in the future we don’t know how to do it.” And they feel friends can often be a big help, especially because friends sometimes know more about their situation than their parents.
