A teacher stood in front of his history class of twenty students just before handing out the final exam. His students sat quietly and waited for him to speak.
“It’s been a pleasure teaching you this term,” he said. “You’ve all worked very hard, so I have a pleasant surprise for you. Everyone who chooses not to take the final exam will get a ‘B’ for the course.”
Most of the students jumped out of their seats. They thanked the teacher happily, and walked out of the classroom. Only a few students stayed. The teacher looked at them. “This is your last chance,” he said. “Does anyone else want to leave?” All the students there stayed in their seats and took out their pencils.
The teacher smiled. “Congratulations (祝贺),” he said. “I’m glad to see you believe in yourselves. You all get A’s.”
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.
Earthquakes happen without warning. They can happen any time of a day，at any point during the year．But don’t worry because most are so weak that they cannot be felt. Only a few big ones hurt people. However, it’s important to know what to do when an earthquake is happening．
Do NOT go outside．You could get injured from falling glass or parts of buildings．If you are outside，stay away from buildings and power lines (输电线)．
Stay under a desk，table，or other strong furniture．Hold on to it．Or stay in a corner of the building．Cover your face and head with your arms and cover your mouth with a towel or clothing．Stay inside until shaking stops and it is safe to go outside．
Keep away from windows，pictures or advertisements on the wall or the building，and anything else that could fall and hurt you．Most people get injured by falling things during an earthquake，not by the shaking itself．
Also keep away from a fire．You could fall down and burn yourself on the fire．
If you are driving when an earthquake happens，stop the car if it’s safe．Stay inside your car until the earthquake stops，and don’t drive near bridges． Try not to stop by power lines or trees．These could fall and hurt you．
When you are about to do something brave, a cheerful wish of “Good luck!” from a friend can be helpful. But if you think you need lots of luck, what else might you do?
In the UK and US there are some strange traditions for bringing yourself a little more good luck. Some are hundreds of years old and some are much newer.
Have you heard the saying “When you wish upon a star”? If you are looking up at the sky on a clear night and you see a sudden flash of light, it is probably a shooting star! Seeing one doesn’t happen very often. The saying goes that if you see one you have been very lucky, and so if you make a wish, it will come true.
Maybe you have heard of the lucky rabbit’s foot. Some people believe that rabbits are lucky animals, so they carry a part of the rabbit, its foot, for good luck. There are all kinds of strange, unclear rules about which of the rabbit’s feet is the luckiest. It is said that this good luck tradition is the oldest one of all. However, as the funny saying goes, “Depend on the rabbit’s foot if you will, but remember it didn’t work for the rabbit!”
People in Britain love trees. If it is autumn and leaves are falling from the trees, some people try to catch the leaves as they fall because they think each leaf they catch will bring them a lucky month in the following year—they will need to catch 12 falling leaves to have a whole of good luck!
