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 ______.
A.make electricity B.produce fertilizerC.build their farm D.feed the cows
【小题2】How are the cow wastes collected into the digester at Blue Farm?
A.Marie Audet does the workB.The job is done by machine
C.The cows lift the cow wastesD.Bacteria get to work on them
【小题3】 According to the passage, which of the following is changed into electricity?
A.The power of moving water. B.The heat of burning coal.
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.reducingB.savingC.recyclingD.changing
【小题5】 What is the main purpose for writing the passage?
A.To introduce a new way of making electricityB.To explain how a new energy works better
C.To show a new rebuilding plan for a big farmD.To explain the reasons for green house effect

Zhalong is a nature reserve in Heilongjiang in north-east China. It is one of the world’s most important wetlands. The reserve covers an area of 210,000 hectares. The area provides food and shelter for wildlife. It is an ideal home for different kinds of plants, fish and birds.

Many birds live comfortably in Zhalong Nature Reserve all year round, while some only stay there for a short time. There are many fish in the wetlands, and the birds can easily catch them for food. Zhalong has long been called “the home of the crane”. There are 15 crane species (物种) in the world. 8 of them are in China and there are 6 species in Zhalong area. It is an important living area for the rare red-crowned cranes. There are not many red-crowned cranes in the world. Every spring and summer, red-crowned cranes lay and hatch (孵化) their eggs in Zhalong.

Some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife. More and more birds are in danger because they do not have enough living space. Many of them died. The Chinese government wants to protect these endangered birds, and they can be safe in Zhalong.

Every year, a lot of tourists go to Zhalong to watch birds. This year, members of our Bird-watching Club are going to study the different kinds of birds in Zhalong and the changes in their numbers. The study begins next month.

7 January, 2014

A new report says more and more international students are attending colleges and universities in the United States. It also notes a large increase in the number of international students from China.

These findings are from the latest Open Doors Report. The report documents the record number of international students in the United States during 2012, 2013 school year. It says more than seven hundred sixty-four thousand four-hundred such students were attending American colleges and universities during the last two years. That represents an increase of almost six percent than one year earlier.

On the other hand, the number of Americans studying overseas (海外) increased by one percent, which reached nineteen thousand this year.

The report says one hundred ninety-four thousand students at American colleges and universities were from

China. That is an increase of more than twenty-three percent over the year before. Peggy Blumenthal, an expert(专家) of international education, described the effect of the increase in Chinese students.

"Now they have been coming for some time. But this year was the highest level ever." She says many Chinese families are able to pay for the highest-quality education for their children. The children mainly choose to study in America.

"We know many of them have enough income to be able to afford to send them anywhere in the world that they want to go. And for the most part, looking around the world, Chinese students still prefer to come to the United States as their choice."

Chinese students are not the only ones who want to attend American colleges and universities. After China, India sends the second largest number of students to the United States for higher education. India has about one hundred thousand students in American schools. South Korea is third with about seventy two thousand students.

Why do so many foreign students study in the United States? Peggy Blumenthal provides one reason.

"The advantage America has is that we have a huge system and a very perfect system. So there are over four thousand universities and colleges in the United States. Among them are some top ones in the world, and what that tells us is there is still a lot of room to host international students."

Foreign students represent less than four percent of the total student population in American higher education. And from Learning English, that's the VOA Special English Education Report. I'm Bob Doughty. Thanks for listening.
