We are lucky to live in a rich country where we have many things. However, some of us sometimes 1 some things.
Electricity is one thing that we waste most. Lights, TVs, radios and other things are often kept on. We should turn them off when no one is using them. It 2 less than a second to do it. Anyhow, not wasting electricity 3 money, because we do not have to pay for the electricity we do not use.
The second thing that we often waste is water. 4 water is precious (珍贵的) and important, so it shouldn't be wasted. It is only a(n) 5 matter of turning off a tap. I am sure everybody can do it 6 if he wants to.
Another big waste is 7. My mother used to cook so much food that much of it was thrown away. I told her we had wasted so much food. She thought l was 8. And now she cooks only what we can 9 up.
It is not right to be wasteful. I find there is a simple way of not wasting things. That is to use only what we need and not to 10 what we do not need. In this way, we can stop being wasteful.
