【正文】 Farewell to junk food is to give yourself a better tomorrow!　　Thank you!　　Teachers and students:　　good morning!　　In order to make the student nutrition publicity work more extensive, indepth and lasting, and promote the institutionalization of the student nutrition publicity work, the Chinese government has decided to designate May 20 as the “Chinese Student Nutrition Day” every year.　　We all know that primary school is the key stage of growth and development, but many students have the bad habits of picky eaters, partial eaters and greedy eaters. Many students do not know how to cherish their health and take responsibility for their health. From today on, I hope you can start to pay attention to your bad habits.　　1. First of all, we should form the habit of not picky and partial eclipse. In daily life, we should eat all kinds of food, fruits, vegetables, fish, eggs, milk and so on.　　2. Secondly, chew and swallow slowly when eating.
