Do you know that there are many things to do to keep our bodies healthy? One answer may be looking after our lungs(照顾好我们的肺). Our lungs help us breathe(呼吸), and breathing keeps us alive! So it is important to look after our lungs.
One way to look after our lungs is by doing physical exercise often. When we play sports, our lungs must work harder. Our lungs breathe in clean fresh air. The air is used by the heart. The heart then pushes blood around different parts of our body to make them healthier.
Another important thing is to choose to do healthy things. This means eating lots of colourful fruits and vegetables, drinking lots of water and getting enough sleep.
But sometimes, we might meet things that aren't so good for our lungs, like smoking. When some people try to ask us to smoke, it's important to say no.
Do you know that May 31 every year is World No Tobacco Day(世界禁烟日)? The subject this year is" Keeping Children away from Tobaccos". Countries around the world should let children know they should not smoke through the Internet.
When we choose not to smoke, we' re not only helping our lungs. We' re also helping our body health.
