When we walk our dog after school, we use energy(能源). When we do our homework, we also use energy. When we listen to music on the radio, we are using energy again.

Energy has many different forms. We use electrical energy when we watch TV. The food we eat has chemical energy. Our bodies also use a kind of energy called motion to move. It is said that a person usually uses energy as much as 9.3 liters of oil every day.

Energy is everywhere, but it’s not freely available. So what can we do to save energy? Let’s start from home. Here’s some advice.

— Turn off the lights, computers, TV and other electrical things when you aren’t using them.

— Take a short shower instead of a long one.

— Lower the temperature setting on your water heater to save energy.

— Don’t open the microwave door too often to check on your food. Every time you open it, you waste some heat energy.

— Don’t open the door of your refrigerator very often. A refrigerator needs a lot of electricity to get cold again after you open it.

Where is Love? How can we find Love? Once a little boy wanted to meet Love. He knew it was a long trip to where Love lived, so he got his things ready with some pizzas and drinks and started off. When he passed three streets, he saw an old woman sitting in the park and watching some birds. She looked very hungry. The boy gave her a pizza. She took it and smiled at him. The smile was so beautiful that he wanted to see it again, so he gave her a Coke. She smiled once again. The boy was very happy.

They sat there all the afternoon, eating and smiling, but they said nothing. When it grew dark, the boy decided to leave. But before he had gone more than a few steps, he turned around, ran back to the old woman and gave her a hug. The woman gave him her biggest smile ever.

When the boy opened the door of his house, his mother was surprised by the look of joy on his face and asked what had made him so happy. “I had lunch with Love. She has got the most beautiful smile in the world.” At the same time, the old woman`s son was also surprised at his mother`s pleasure and asked why.
