Most ants are hard workers and often work from six o'clock in the morning until ten o'clock at night. The work is divided among the worker ants and every ant has some work to do. We do not know how they decide what everyone is to do because they do not talk. Some people think ants follow each other by their sense of smell. Ant's often lived to be a year old, and some can live six or seven years. They get their food from lice's called cows. The ants milk these“cows” by tapping the lice's gently until a drop of syrup“milk”comes out. Then they drink it. Ants take very good care of these lice's and often put something on them to keep them from rain.

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.

C．The power of sunlight.	D．The heat of the methane gas

【小题4】The new way of using cow wastes at Blue Farm might be best described as ______.

A．reducing

B．saving

C．recycling

D．changing

【小题5】 What is the main purpose for writing the passage?

A．To introduce a new way of making electricity	B．To explain how a new energy works better
C．To show a new rebuilding plan for a big farm	D．To explain the reasons for green house effect
