The Chinese nutritionist Yu Ruomu, had made a ten year project in order to enhance the nutritional status of the whole national students. As we all know, human body needs enough nutrition to function. As to the students, lack of nutrition will lead to mental retardation, hyperactivity and so on. So it is very important for us to eat different kinds of food. 
從1989年開始，全國學生營養日定在每年的5月20日。這個節日為中國廣大的學生做出了極大的貢獻。中國的營養學家于若木，為了提高全國青少年的營養狀況，制訂了一個十年的營養計劃。我們都知道，人的身體需要足夠的營養才能正常運轉。對于學生來說，缺乏營養會導致精神發育緩慢，多動癥及其他癥狀。所以，吃不同的食物對我們來說非常重要。

According to the least survey, Chinese students lack of Vitamin A, calcium, iron and zinc. Some children are too particularly with food that they don’t eat staple food; instead, they turn to different kinds of snacks. As a result, they may become sick because lack of vitamins and other elements. If we want to keep fit and keep the doctor away, we better do something.根據最新的調查顯示，中國學生缺乏維生素A、鈣、鐵、鋅。一些孩子太挑食，都不吃主食，反倒去吃各種零食。結果就因為缺乏維生素和其他微量元素，導致身體出現了問題。如果我們想身體健康，不找醫生，那我們最好注意飲食。

First of all, we should eat different kinds of fruits and vegetables. Do not eat too much sweet or drink too much soft drinks. Early to bed and early to rise, do more outdoor exercises; don’t play too many computer games. Last but not least, take the body examination once a year. If you have any problems, you can fix them immediately. Prevention is better than cure. Only in these ways, we can stay in good health. 首先，我們要吃不同的蔬菜水果。不要吃太多的甜食或者喝太多的軟飲料。早睡早起，多做運動，別玩太多的電腦游戲。最后，每年定期檢查一次身體。如果身體有什么不適，立馬去治療。預防勝于治療。只有這樣，我們才能有個好的身體。
