How to save
Our government is aiming to build an“Economized society(节约型社会)”.It is our duty to work hard to achieve this goal.As students,we should do something to help.
First,we'd better save more water,paper and electricity.For example,turn off the lights when we leave the classroom,and remember to turn off the tap after washing our hands.Next,we should take our own bags in shopping instead of using plastic bags from supermarkets.
Then don't waste food.We'd better eat up all the food when we have meals.And don't throw uneaten food everywhere.Finally,we'd better go to school on foot or ride a bike instead of taking a car.
In a word,I think one thing we should keep in mind is that no matter what a small effort we make,it does make a difference.
