When you turn on the lights at New Farm,you are using electricity that comes from cows.

Cows produce a lot of waste. One cow can create about 135 liters(升)of waste in a single day. There are about 1,000 cows at New Farm. Imagine how much waste they produce every day!

Some of the cow waste is used as fertilizer (肥料)for the fields. But what about the rest? It used to be a problem. But now New Farm has a new way of using cow waste. They use it to produce electricity.

Here's how it works:A big machine moves around to collect the waste. "Hie cows aren't afraid of the machine," says Mr. Smith,the owner of New  Farm. "TTiey have got used to it,and just lift one foot and then another to let it go by.” After collecting enough waste,the machine then pours it into a big digester(化糞池)In the digester,bacteria(細(xì)菌)get to work and much methane gas(沼氣)is produced. Methane gas is known as a " greenhouse” gas because it keeps heat just like a greenhouse does,causing our earth to warm up. But the digester has a good result. Its gas is kept and used to power electric generators(發(fā)電機(jī)), At New Farm,the generators make enough electricity to provide for 400 homes. Mr. Smith sells the electricity his farm does not need.

How to Be a Greener Person?

What does it mean to be a greener person? "Green" is more than just a 1   It also means taking special steps to protect the land, and the air we breathe. Why green? Plants are green, and 2    them the earth wouldn't be a lovely place. So here's a four-step guide:

Reduce!

When you use less of something,you do a good thing for the earth. For example,a 3    shower means you use less water, and less fuel (燃料)too. 4    your house uses fuel to run the water heater.

Reuse!

At times we want to throw things away and buy new things. Many times, if you don't need 5        any longer, someone else just might need it. For example,  if your baby grows out of 6       ,why not give them to another family who has a little kid?

Recycle!

Recycling has never been easier. Leave the things which you don't need right in front of your house and someone who needs them will7    them up. Tell your parents you'll become " Head of Recycling" for your house. That means you'll collect the recyclable things in your home and tell others  8   things can be recycled.

Enjoy!

It's true that 9    is a problem, but the earth is still a huge and beautiful place for you to live and study. You can start by 10    the naturally beautiful places in your hometown ― go for a hike,visit local nature centers and gardens, climb mountains and so on.
