The weekend is here! You can sleep longer(更长) and get up later(更晚) than usual(比平时). But is it a good idea to sleep longer during weekends?

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.
