　　Doing Our Part
From the picture,we can see that the boy is dropping litter outside of the trash bin.The ground looks dirty.I think what he does is wrong.
As middle school students,it is' our duty to behave well and try to make the school more beautiful.We shouldn’t talk loudly in public.Dropping litter is not allowed in or out of school.Never waste food while eating in the dining room.Also we are supposed to get on well with the classmates.Being polite to teachers is also very important.
In a word,if everyone can do our part,we can make a difference to the world.
