Dear fellow students，
Our school is preparing to help students develop good habits．But there is a serious phenomenon in our school—some students are spending too much money on snacks．
Eating snacks is a waste of money．It’s also a bad habit that we should get rid of．In addition，most snacks have too much fat and sugar．They are unhealthy food．Eating snacks may lead to fatness and illness．To make matters worse，some students litter the food wrappers everywhere．
As high school students，we shouldn’t act as little children any more．Dear fellow students，let’s form good eating habits and say no to snacks!
