night into day ever since. But today, many want to turn the light off.
The European Union (欧盟) recently decided that by 2009, people should stop using the Edison-style light
bulb. Instead, they should use compact fluorescent lamps (小型荧光灯, CFLs节能灯).
"CFLs save energy and last longer. They can save money in the long run," said a British official. CFLs use
67 percent (67%) less electricity than the older bulbs. They last up to 10 times (倍) longer. Scientists say that
if everyone used CFLs, electricity use would be cut by 18 percent. There would also be much smaller amounts
of greenhouse gases (温室气体) given off.
But it's difficult to make people change their lighting habits. First the CFLs are more expensive. They cost
eight times the price of the older bulbs. Many people don't like the CFL bulb. They find it too bright. You
cannot change the light of a CFL, either.
CFLs have been around for several years. However, the older lights still make up about two-thirds (2/3) of
total (全部的) light bulb sales.
( )2. Countries in the European Union will not use Edison-style bulbs by 2009.
( )3. Using CFLs helps protect the environment.
( )4. If you get an older bulb for l Euro (欧元), the CFL bulb will cost you 8 Euros.
( )5. CFLs have been widely used instead of the older bulbs for several years.
