By using less energy, you can reduce pollution that causes global （全球的） warming, An energy-saving light bulb （灯泡） uses less energy to produce the same amount of light as a regular bulb, Use the chart to compare a regular bulb with an energy-saving bulb．

	Regular Light Bulb	Energy-Saving Light Bulb
Name	Incandescent light bulb	Compact fluorescent light bulb（CFL），energy saver
Price	50 cents	$5
Cost of energy	Used in one year （4 hours a day）：$9.3	Used in one year（4 hours a day）：$2.5
Energy used	75 watts（Most of this energy is wasted as heat．）	20 watts
Lifetime	1.000 hours	10,000 hours

（   ） 1．How much more energy does the regular bulb use than the CFL bulb if they are used for a year （four hours every day）?

A．75 watts.          B．55 watts.          C．20 watts.                D．50 watts.

（   ） 2．How many regular bulbs does a CFL bulb equal （等同于） in lifetime?

（   ） 3．I bought a regular bulb and Tom bought a CFL bulb．If we both used the bulb for four hours a day, how much money would Tom save in all after a year?

A．$ 2.3.             B．$ 90.5.            C．$ 6.8.             D．$ 95.5.

（   ） 4．Why do regular light bulbs use so much energy?

      A．They make more light than CFL bulbs.

      B．They can be used for a longer time than CFL bulbs.

C．They waste most of their energy as heat.

D．It's because of their shapes.

（   ） 5．What does the writer try to tell us according to the passage?

A．Using more energy can produce less pollution.

      B．Energy-saving light bulbs are cheaper than regular ones in shops.

      C．It is a good idea to use energy-saving CFL bulbs instead of regular ones.

D．An energy-saving light bulb is easier to get broken.

 Just stop     (complain ) about the air pollution. Just think about what we can do to reduce it.

We all need a healthy environment, but we produce waste every day and it does harm to our environment. Though we are young, we can still do something to help. In fact, even the simplest everyday activities can make a real difference to the environment. Here are some ideas for you to live a green life.
Remember these three words: reduce, reuse and recycle.
Reduce means “use less”. Don't waste things. This saves money and reduces pollution and waste going into the environment. Before we buy something new, think if it is really necessary or maybe the old one will be just as good! When we do buy things, choose local products if possible, and try not to buy too many things from abroad.
Reuse means “use again”. Use things for as long as possible. When we buy things, make sure that they last a long time. We should take care of them so that they will last, and we should repair them if we can instead of throwing them away and buying new ones. Don't use a paper cup or a paper bag. It’s better to use a china cup and a lunch box because you can use them again.
Recycle means “change things into something else”. Although it takes energy to change something into something else, it’s better than throwing things away or burning them. Find out what can be recycled in your neighbourhood and take part in recycling programmes. We should also buy products made from recycled materials, such as recycled paper, to help save trees.
