5 . We always discuss about health, especially for kids. But what is health? “Health” means eating well, getting enough exercise, and having a healthy weight. Let’s read the following rules. They can help us stay healthy.

Eat a variety of foods, especially fruit and vegetables. We all know that eating fruit and vegetables can help us stay healthy, but many of us only eat our favorite foods. Remember that we can only get the nutrition (营养) we need by eating different kinds of food, especially fruit and vegetables.

Drink water and milk most often. Everyone knows that water is important. Besides that, kids need plenty of calcium (钙) to grow strong bones, and milk has a lot of it. Every day, we should drink at least three cups of milk (1,300 milligrams of calcium) when we are 9 years old or older. We should also try to have less sugary drinks, like soda and coca. They include a lot of added sugar. Sugar just adds calories (卡路里), not important nutrition.

Listen to our body. When we are eating, notice how our bodies feel. When our stomachs feel comfortably full, stop eating. Eating too much makes us feel uncomfortable. If we do it too often, it can make us unhealthy and fat.

Limit screen time. What’s screen time? It’s the amount of time we spend watching TV, movies, and playing computer games. The more time we spend on these sitting-down activities, the less time we spend playing sports, like basketball, and doing other activities like bike riding and swimming. Try to spend no more than 2 hours a day on screen time.

Nowadays more and more people care about health. But how can we keep     1     (health)? In my opinion, it is important     2     (follow) some rules.

First, we should take some exercise every day. A study shows that getting lots of exercise     3     (make) the heart beat faster and the lungs (肺) work harder. This helps lower blood pressure. That’s why more and more people take an active part in different     4     (kind) of sports and exercise.

Second, we’d better eat more fruit and vegetables,     5     we shouldn’t eat too much meat such as beef. The food people eat is connected with their health. Meat has more fat than fish. Fat can fill in the arteries (动脉), and then     6     (easy) cause a heart problem.

At last, giving up bad habits like smoking (吸烟) and drinking too much alcohol (酒) is also     7     important way to keep healthy. Smoking and drinking alcohol are bad for     8     (people) health, and everyone should stop them.     9     (lucky), not many people follow this piece of advice.

If we can follow these rules, we’ll live a     10     (healthy) and happier life.

Healthy living for most people means having a healthy lifestyle. Here are some tips that people should follow in their     1     life. Healthy eating plays     2     important role. Make sure you have three meals a day on time. Good breakfast, rich lunch and less dinner are suggested. Try to     3     food high in sugar.

Regular exercise also leads to a healthy lifestyle. It can help you keep your weight under     4     and make self-confidence at the same time. It’s a good idea     5     you to exercise for thirty minutes each time, at least three days a week. Shall we do     6     every day? It depends. However, every time you exercise, you put     7     at risk of getting hurt, so remember to do it in a right way.

    8     sleep is the key to a healthy lifestyle. For most people, it is necessary to keep eight hours of sleep each day.     9     you don’t fall asleep within twenty minutes, do something relaxing. Reading and listening to light music are good     10    . And then you may fall asleep soon.
