we can do something for society and the environment
by making small changes. Firstly, make sure that
the lights are turned off when we finish our work
and leave the room. Secondly, we should save as
much paper as possible. Thirdly, it is important for
us to form the habit of turning off the tap after we
finish using it. What's more, we should not spend
money buying unnecessary things. When we eat,
we'd better not use one-off chopsticks and we
shouldn't waste food.
In a word, saving energy is very important.
Let's work together from now on.
