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 (跳過) 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.

Children arc children after all, and most of them speak their mind. When they are just toddlers(幼兒), they are all lovely and lively. And it's so interesting to watch them speak like a grown-up. But as they grow, these same kids seem annoying and ill-mannered if they try to be a grown-up.
Conflicts(矛盾）go between parents and children. It's hard to tell who are right and who are wrong. A child of 7-8 always finds some reasons to have a conflict with it's parents. Whether it is about some toy, studies, a party or a company, there is always a difference between them. And it becomes worse when they answer you back. Scientists tell us that children should be treated with care. Yes, sure they should respect their elders.
We are partly responsible(有責任的）for this. At an early age we encourage children to behave like adults, just because we find it funny. The kids on the other hand consider this same behavior as normal and get used to it. And when it is not funny for us any more, we expect them to stop it, but by then it is already too late. Only when they reach a certain maturity will the children realize that answering back and being rude are not acceptable(可接受的).Until then, most of the time their behavior is difficult to change, unless by force(暴力）.And use of force is against the every good idea, as it weakens the child's confidence.
So it is one thing to bring a child into this world but quite another to make them into well mannered citizens. The best way is to be a good example ourselves, as our children are the mirrors of us adults.
小題1:_______are all lovely and lively.
A．Children B．ToddlersC．KidsD．Grown-ups
