【考點(diǎn)】倡議書(shū)；提綱作文；身心健康．

【答案】Dear students，
Some students in our school have the habit of eating snacks instead of meals，which is harmful to their health.We'd like to call on all students to develop healthy eating habits.
As we all know，if we eat snacks frequently ，the chemicals they contain will build up inside our body and harm our body.Besides，snacks don't provide enough nutrients that our body needs to function well for the whole day.Therefore，we would call on you to take meals instead of snacks.
Let's have a healthy diet from now on ，Let's eat more fruit and vegetables every day to prevent diseases so that we can keep healthy.
