Hello, everyone!
It’s important for us to keep healthy. Many students are   71; it’s bad for our health. We shouldn’t   72  , like hamburgers and French fries. As for eyes, watching too much TV and spending much time playing computer games make our eyes near-sighted. Some students like eating sweet food, so they often have a   73. A few students sometimes have  74   because they never eat breakfast. If we want to keep in good health. I think we should    75. So let’s try to do it!
