   We are lucky to live in a rich country where we have many things. However, most of us usually 1       some things.

Electricity is one thing2      we waste most. Lights,TVs, 3       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 4       less than a second to do it. Anyhow,not wasting electricity saves money? because we do not have to 5       the electricity we do not use.

The second thing that we often waste is water. Fresh water is precious, 6       it shouldn't be wasted. It is only a simple matter to turn off the tap. I am sure 7       can do this easily if he wants to.

8       big waste is food. My mother 9       cook so much food that much of it was thrown away. I told her we had wasted so much 10       . She thought I was right and now cooks11       what we can eat.

It is not 12       to be wasteful. I find there is a simple 13      of not wasting things. That is to use only what we 14      . Do not touch what we do not need. 15      this way,we can stop being wasteful.
