从1989年开始，全国学生营养日定在每年的5月20日。这个节日为中国广大的学生做出了极大的贡献。中国的营养学家于若木，为了提高全国青少年的营养状况，制订了一个十年的营养计划。我们都知道，人的身体需要足够的营养才能正常运转。对于学生来说，缺乏营养会导致精神发育缓慢，多动症及其他症状。所以，吃不同的食物对我们来说非常重要。

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.根据最新的调查显示，中国学生缺乏维生素A、钙、铁、锌。一些孩子太挑食，都不吃主食，反倒去吃各种零食。结果就因为缺乏维生素和其他微量元素，导致身体出现了问题。如果我们想身体健康，不找医生，那我们最好注意饮食。

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，我们要吃不同的蔬菜水果。不要吃太多的甜食或者喝太多的软饮料。早睡早起，多做运动，别玩太多的电脑游戏。最后，每年定期检查一次身体。如果身体有什么不适，立马去治疗。预防胜于治疗。只有这样，我们才能有个好的身体。
