光盘行动英语作文：
Clear your plate
Please join in Clear your plate campaign。
Now， some of us students like buying a lot of snacks。 They eat a lot even if they were not hungry。 If they dont like the food， or they cant eat up the food， they will throw it away。
It is really a bad thing。 We have wasted lot of food。 And at the same time， it is bad for the students health。
So boys and girls， lets change our habit。 When we have dinners in restaurants， dont order too much food。 And try to eat up all the food we ordered。 If we cant eat up all of them， just pack them and bring them back home to eat。 Please give up the snacks between meals。 Encourage your classmates and parents to join us。 If you find somebody is throwing away food， just stop them。
Come on， dear friends。 Lets start with ourselves。
