Dear friends,
I’m Li Hua. I’m very glad here to give you a short speech. As we all know, we are what we eat. As a result, it’s very important for us to form healthy eating habits. Therefore, bad eating habits are still very common among us students. Some of us often went to school without breakfast. Some like to have snacks. Others are particular about food, and still some eat or drink too much. All these bad habits will surely do harm to us health.
To keep fit, we should have balancing and healthy diets, they generally include proper amounts of fish, meat, fruit, vegetable as well as staple food. Remember to eat fewer snacks and little junk food. Besides, we had better to have meals regularly.
On my opinion, we should try to build up strong body. Only in this way can we have enough energy to study better.
That’s all. Thank you!
