We are lucky to live in a rich country where we have many things. However, most of us usually    some things.
Electricity is one thing that we waste ____. Lights, TVs,     and other things are often kept on even when no one is using them. We should turn them off when we do not need them. It         less than a second to do it. Anyhow, not wasting electricity save money, because we do not have to         the electricity we do not use.
The second thing that we often waste is water. Fresh water is precious(宝贵的)，       it shouldn’t be wasted.It is only a simple matter of turning off a tap*. I am sure         can do this easily if he wants to.
       big waste is food. My mother         cook so much food that much of it was thrown away. I told her we had wasted so much        . She thought I was right and now cooks __   _  what we can eat.
It is not          to be wasteful. I find there is a simple        of not wasting things. That is to use only what we         . Do not touch what we do not need.          this way we can stop being wasteful.
