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.We learn from the text that the Audet family is using cow wastes to ______.
| A．make electricity | B．produce fertilizer | C．build their farm | D．feed the cows |

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

One day in 1924, five men who were camping in the Cascade Mountains saw a group of huge apelike creatures coming out of the woods. They hurried back to their wooden house and locked themselves inside. While they were in, the creatures threw rocks against the house. Several hours later these strange hairy giants went back into the woods.
After the men returned to the town and told the people about their adventure, . These were the people who remembered hearing tales about footprints of an animal that walked like a human being.
The five men, however, were not the first to have seen these creatures called Bigfoot. Long before their experience, the local Native Americans were certain that a group of apelike animals had been living in the neighboring mountain for centuries.
In 1958, some workers, who were building a road through the jungles of Northern California, often found huge footprints in the earth around their camp. Then in 1967, Roger Patterson, a man who was interested in finding Bigfoot, went into the same jungles with a friend. While riding, they were suddenly thrown off from their horses. Patterson saw a tall apelike animal standing not far away. He managed to take photos of the hairy creature before it disappeared in the jungles. When Patterson’s photos were shown to the public, not many people believed his story.
Richard Brown, an experienced hunter, discovered a similar creature. He saw the animal clearly through the telescopic lens (望远镜头) of his rifle (步枪). He said the creature looked more like a human being than an animal.
Later many other people also found deep footprints in the same area. In spite of regular reports of sightings and footprints, most experts still do not believe that Bigfoot really exists (存在).What did the five campers do when they saw a group of apelike creatures?
| A．They fought with the creatures by throwing rocks at them. |
| B．They ran into the woods and hid there for several hours. |
| C．They made a big fire to frighten the creatures away. |
| D．They quickly ran back into their house and locked the door. |
Which of the following can be put in ?
| A．however, only a few people accepted their story |
| B．all the people said they had seen the animal |
| C．some said they were making up their own story |
| D．only those who had killed the creature believed them |
. Who were the first to have seen these apelike creatures?
| A．Some workers. |
| B．Richard Brown. |
| C．The local Native Americans. |
| D．Roger Patterson and his friend. |
The word neighboring may mean .
| A．great | B．nearby |
| C．snowy | D．tall |
The BEST title for this passage would be “ ”.
| A．The adventures of five campers | B．The experts and Bigfoot |
| C．The creatures called Bigfoot | D．The adventures of Bigfoot |

Success is a key goal for most people. We are always trying to find the way to success, which means power, pride and glory (荣誉). There have been many stories of success I was told since I was a child. From then on, I have been hoping to be successful.
What is success? Different people have different opinions. To start with, some people, such as workers and waiters / waitresses, are looking forward to becoming rich, which allows them to buy what they want. They treat it as success. What’s more, some contestants, such as players, sportsmen and singers, are always trying their best to win. As long as they win, they believe that they are stronger than others. Last but not least, there are some other people who enjoy helping others. As the saying goes, the roses in her hand, the flavor (香味) in mine. Through helping others, we can also feel happy and successful.
In my opinion, success is quite simple. It means you can live the life you want and you can feel happy very often. Sometimes, money cannot bring you happiness, and you can’t have the feeling of success, because money is just the tool (工具) to achieve your goal but never the goal. Therefore, look for what you really want and then work hard for it. Then you are close to success.

| Our 4th-grade class is studying how things have changed over time. To get more information, I spoke with my great-grandmother to find out what her school was like when she was my age. The following is what she told me. |
My school was called Algoe School. It was built in 1902 and was a one-room school. There was only one teacher, but the students were from different grades. Algoe School sometimes had as many as 18 students, but once there were only two.
We all had jobs to do every day. The teacher rang the school bell every morning. There was a flagpole (旗杆) in front of our school. We raised the flag every morning. At noon break, one student cleaned the blackboard. Some students swept the floor. And two students had the job of walking to a nearby farm to bring back a big bag of drinking water.
In winter, our school was heated by a wood-burning stove (炉子). On very cold mornings, we all sat around the stove and the teacher gave us lessons. Although it was very cold, we all felt happy.
