C 跨生物·食物
Food is very important for all living things. It helps our body grow and keeps all parts of our body working well.
We need to eat healthy food every day. We have three main meals a day: breakfast, lunch and dinner. Each meal gives us energy for study and sport.
Different foods give us different kinds of nutrition. Rice and noodles are main food. They give us much energy. Vegetables and fruit are rich in vitamins. Vitamins help our body fight sickness and keep us healthy. Eggs, milk and fish help us grow tall and strong.
Water is necessary for our life. About 70% of our body is made up of water. It helps carry nutrition to every part of our body.
Fast food and too much sweet food are unhealthy. They cannot give us enough good nutrition. They are bad for our body and make us get fat easily.
Healthy eating is very important. It helps our body grow well and work well in our life.
