    We are lucky to live in a rich country where we have many things. However, most of us usually1some things.

     Electricity is one thing that we waste most. Lights, TVS, 2and 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 takes less than a second to do it. Anyhow, not wasting electricity save money, because we do not have to care forthe electricity we do not use.  The second thing that we often waste is water. Fresh water is precious, 3 it shouldn't be wasted. It is only a simple matter of turning off a tap. I am sure 4  can do this easily if he wants to.  5 big waste is food. My mother 6 cook so much food that much of it was thrown away. I told her we had wasted so much 7. She thought I was right and now cooks mainly  what we can eat.

    It is not 8 to be wasteful. I find there is a simple way of not wasting things. That is to use only what we9. Do not touch what we do not need.  10 this way we can stop being wasteful.

      Light and shadow（影子） are friends.They usually go together. We receive light every day. At the same time, we produce shadow.

      Light cannot shine through you. Your body stops it from passing. There is a dark spot on the ground next to you. The light cannot reach the dark spot. This is your shadow.

      At noon the sun shines over your head. Your body stops very little light from reaching the ground.

      We love light, especially sunlight. Without sunlight, life on earth is impossible. Most of us like to stand in the shadow of a tree in summer. But some people are afraid of their own shadow at night. They do not want to walk in a dark street. They do not want to see the shadow, either. But still light and shadow usually go together.
