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 |
How are the cow wastes collected into the digester at Blue Farm?
| A．Marie Audet does the work | B．The job is done by machine |
| C．The cows lift the cow wastes | D．Bacteria get to work on them |
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 |
The new way of using cow wastes at Blue Farm might be best described as ______.
| A．reducing | B．saving | C．recycling | D．changing |
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 |

Sharks (鲨鱼) are the most frightening animals in the sea. Sometimes we can see sharks swimming in the sea around Hong Kong. People put nets around some beaches to protect swimmers. When there is a "shark's flag", people must slay on the beach. It will be too late if a shark can swim sixty kilometers an hour to you.
There are 30 kinds of sharks and 25 kinds of them are dangerous. The whale sharks are very big. They can grow to 18 meters long, but they are not dangerous to people. The jaws (大白鲨) and the tiger sharks are the most dangerous kinds of sharks.
Do you know all sharks must keep swimming, or they will go down? All sharks can feel everything that happens around them. We must keep calm and don't make any noise when a shark is swimming near you.

Accidents often happen. It's necessary for us to remember these tips.
On your way home or to school: Wait for the green traffic light, and look left and right before you cross the road. If you see a car coming, don't cross until it really stops.
At school: Never run around too fast at school. When students around you begin to push, try to hold something. If you fall down in a crowed (拥挤的) place, cover your head with both hands.
When there's a fire: Keep quiet and leave quickly. Use a piece of wet cloth to cover your mouth and nose so that you don't breathe in smoke. If your clothes catch fire, drop to the ground and roll (滚动) from side to side to put out the fire.
For eating: Wash fruit like apples or pears carefully before you eat it. And if your food looks or smells bad, don't eat it.
