When the Audet family turns on the lights at Blue Farm, they are using electricity that comes from cows—cow manure (粪肥), to be specific.
Cows produce a lot of wastes. One cow can create 30 gallons of wastes each day. Now imagine the output of over 1,000 cows at Blue Farm. That’s really a big amount.
When farmers clean their barns, they put the wastes in a big heap, and spread some of them on their fields for fertilizer(肥料). But now places like Blue Spruce Farm have a new way of using cow wastes. They use them to produce electricity.
Here’s how it works: A big machine moves back and forth cleaning the barn floor. “The cows aren’t bothered,” says Marie Audet. “They are animals of habit; they get used to it, and just lift one foot and then another to let it go by.”
The machine pushes the manure into a big 600-gallon tank like a small swimming pool. The tank is called a digester (化粪池) because what happens there is just like what happens inside a cow: Bacteria(细菌) get to work and continue to digest the manure.
Methane gas (甲烷、沼气)in the atmosphere is known as a “greenhouse” gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That’s an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators (发电机).
At Blue Farm, the generators make enough electricity to power 400 homes. The Audet family sells the extra electricity they can’t use themselves.
【小题1】We learn from the text that the Audet family is using cow wastes to ______.

We were going to play against a team from a country school.They didn’t come until the last minute. They looked worse than we had thought. They were wearing dirty blue trousers and looked like farm boys.We sat down for a rest. We felt that we didn’t need any practice against a team like that.

The game began. One of us got the ball and he shot a long pass to our forward （前锋）. From out of nowhere a boy in an old T-shirt stopped the ball and with beautiful style, he shot and got two points. Then another two points in a minute. Soon the game was all over. We were beaten by the country team.  

After that, we thought a lot. We certainly learned that even though your team is very good, you can’t look down upon the others and still need to do you best. And the most important lesson we learned was: One can’t judge (判断) a person or a team only by their clothes.
