阅读理解:

The earth is faced with the serious power problem now and all of us are affected by it. Let us look at how we can save power.

Computer: More often than not, we do not turn off our monitors(显示屏) even after we have shut down our computers. And we often leave the computers on when we walk away to do something else. Keep the monitor and the computer off when you are not using them. You will help save power.

Air Conditioner: Set the air conditioner at the lowest or highest temperature that you are comfortable with, depending on the season. Try not to set it at too-high or too-low temperatures. This helps you save lots of power.

Washing Machine: Do you use your washing machine frequently? Do you use it even when there are not many clothes to wash? Reduce the times of washing by washing plenty of clothes every time.

Television: Please unplug the power plug of your television set when not using it. This may not sound like a big deal but this little step will help you save power.

Refrigerator: Do you always put hot food into the refrigerator? Cool cooked food to the room temperature before placing it into the refrigerator. You can also take cold or frozen food out of the icebox long before the mealtime, so you can heat it with less power.
