Some middle school students aren’t doing enough in “advocating thrift and being
civilized.” We’re sorry to see that there is still some waste in our school! For
example, some often leave the taps on after washing their hands. In the dinning
hall, a lot of food can be seen left after the meals. What’s worse, we often
find that waste paper is thrown everywhere, which makes others feel
uncomfortable. In addition, some students like to write or draw on the wall or
on the desk.
As middle school students, we should develop good habits and
stop wasting anything. Let’s do it from now on!
