一篇阅读题=
The summer vacation is almost here.But your computer and television may be on holiday too as power cuts hit China.
This year energy shortages cover 24 provinces across the county ,8 provinces more than last year.
These shortage can usually be blamed (归咎) on air conditioners.Wuhan,in Hubei,where temperatures can be 36℃,is a good example.As much as 100,000kw of electricity would be saved if people set their air conditioners one degree higher than normal.
Here's how you can help to save energy.
·Use air conditioners less.Set the temperature a little bit higher than normal and turn it off one hour before you go out.
·Turn off the lights when you leave a room.
·Unplug (拔掉插头) electricity devices (电器) when not in use.Many televisions and computers use electricity even when they are turned off.
·In rooms where you don't often stay for long,close curtains during the day to keep off the sun,especially on windows that face south or west.Open them in the evening to let cool air in so you may not need to use air conditioners.
·Take shorter showers.Water heaters use a lot of energy.
·Open your refrigerator door only when necessary.Each time you open the door,the compressor (压缩机) will run for 8-10 minutes to keep the inside cold.
·Ask your parents to replace your regular lights with fluorescent (荧光的) lights.They use about a fourth of the energy of regular lights.
