急求一篇英语作文或者对话题目如下：

In one of our class-meetings,we had a heated discussion about whether the students in senior grade 3 should have some nutrition.60 percent of the class think that,if we keep on exercises,we needn't any nutrition.Also,most of the nutrition is very expensive.No doubt, it will increase the family expense if you have some nutrition every day. Meanwhile,over-having nutrition will do great harm to your health.
But 40 percent of the class agree that many students feel tired withour lessons,and we have not much time to do any exercises.They think that nutrition can help us recover.
Anyway,diffreent people will have different ideas on the same problem. And it depends on the individual,and depends on the personal economy,personal body state and personal living habit as well.
