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 t he 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.We learn from the text that the Audet family is using cow wastes to ______.

People began to make robots about several hundred years ago. In the past, some of the early ones looked like animals or humans. However, they couldn’t talk and were pretty dumb. They worked like clocks and did the same things over and over again.
Now modern robots don’t always look like people. Some are like big machines; others are nothing but long arms attached to boxy(箱子般四四方方的)bodies. However, modern robots are smart. Some can solve problems on their own. Their brains are computers and their eyes are sensors(传感器). Motors(发动机)help them move.
In the future, robots will learn from their mistakes more than they do now. They will be smarter. It’s possible that we will have robot judges, robot household workers, and robot factory workers. Robots will help people to do more things. How long is the history of robots?
| A．Hundreds of years. | B．Several hundred years. |
| C．Seven hundred years. | D．A hundred year. |
What’s the possible meaning of dumb?
| A．Talking like people. | B．Clever. | C．Unintelligent (迟钝). | D．Cute. |

Which of the following is NOT true about modern robots?
| A．Some robots can solve problems on their own. |
| B．Some robots are like big machines. |
