范文背诵

    How to eat in a healthy way

    Hello, everyone, I’m Li Hua. Today, my topic is about how to eat in a healthy way. First, we should hardly ever eat unhealthy food or drink such as hamburgers and ice-cream because they are not good for our health. Second, try to eat more vegetables and fruits because they can make us healthy.

   My eating habits are good. I eat many vegetables and fruits every meal. I only eat unhealthy food about once a month. I always drink milk and eggs for breakfast.

   I hope everyone can eat in a healthy way.
