More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that's why there are about 1.4 billion bicycles and only about 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

    Get on a bicycle and ride around your neighbourhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You can bike to work and benefit (受益) from the enjoyable exercise without polluting the environment. You don't even have to ride all the way.

    Folding (可折叠的) bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by accessing on airline websites. Not all airlines are bicycle-friendly to travellers.

    Health Benefits of Bicycling:

    It helps to prevent heart diseases.

    Bicycling helps to control your weight.

    A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a year. Bicycling can improve your mood (心情).

    Exercise like bicycling has been shown to make people feel better, more relaxed and self-confident. Bicycling is healthier than driving.

    Today more and more children wear glasses before going to middle school. They keep their eyes watching TV or playing computer games for a long time. Eyes are the windows of our hearts (心). We use our eyes to see everything around us, so we should know how to protect our eyes.

    Love our eyes. When we open (睁开) our eyes every day, we can see the lovely friends and parents, beautiful flowers and green trees. If our eyes don't work, how can we see the world. In our eyes, everything and everywhere is dark. It's like a house with no light (光). How important our eyes are!

    Relax our eyes. First, stop to relax 30 minutes when using the computer for an hour or two. Next, remember to do eye exercises every day. Then, looking at green trees also helps a lot. In these ways, our eyes will feel relaxed.

    Have good habits. When writing homework and reading, it is important to keep a distance (距离) of 30 cm between your eyes and books. Remember to use our eyes in a right way. Don't read in bed or on a moving bus. Eat something healthy for eyes, such as carrots, fish and eggs.

    Follow my advice (建议) and get good habits. It's time to say goodbye to thick (厚的) glasses.

Better hygiene (卫生) habits can help you stay healthy

According to the World Health Organization, 60 percent of people's health problems are related(与…相关) to everyday hygiene habits. As the COVID-19 spreads across the world, governments and organizations in many countries have suggested that people should pay more attention to their daily hygiene practices.

In China, for example, people usually share dishes together at the dining table. But this habit has a high risk of spreading diseases through saliva(唾液). To fight against COVID-19, many cities in China, including Beijing, Shanghai and Guangzhou, have called on people to order separate(分开的)meals or use serving chopsticks(公筷) to take their food. Many people also suggest that Chinese should continue these habits after the outbreak.

In the US, the Centers for Disease Control and Prevention has asked people to develop healthy hygiene habits. For example, people should cover their mouth and nose with a tissue when they cough or sneeze.

    According to a survey by YouGov, a British market research company, many Americans have taken action to change their daily habits in the face of COVID-19.

Early to bed and early to rise makes a man healthy, wealthy (富有) and wise (聪明). This is an old English saying. It means that we should go to bed early at night and get up early in the morning. If we do, we shall be healthy. We shall also be rich and clever.

Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours' sleep every night. If you go to bed late, you can't have enough sleep. Then you can't think carefully and your homework will be wrong. You will not be wise and you may not become wealthy!

Some people go to bed late at night and get up late in the morning. This is not good for them. We should sleep at night when it is dark. The dark helps us sleep well. When the daylight comes, we should get up. This is the time for exercise. If the body is not used, it will become weak.

Exercise keeps it strong. Exercise helps the blood (血液) to move around inside the body. Blood takes nutrition (营养) to all parts of our bodies. The brains (大脑) in our heads also need blood. We think with our brains. If we keep our bodies healthy, and take exercise, we can think better!

Our bodies also need air to breathe (呼吸). Without air we will die. Get up early in the morning and we can have plenty of clean, fresh air. That will keep us healthy and happy.
