Australia has promised to introduce the most comprehensive （全面的） carbon trading program outside Europe in 2010. The government in Canberra plans to cut greenhouse gas emissions (排放) by at least five percent by 2020, but it could make bigger reductions if other countries agree to tougher targets.

    The Australian government warns that without tough environmental measures the country could lose key industries and jobs. Climate Change Minister Penny Wong says the economy is under threat and decisive action is needed.

    Central to the government's climate change plan is a carbon emissions trading program that will be introduced within two years. It would involve one thousand of the nation's biggest companies and would cover about three-quarters of Australia's greenhouse gas emissions.

    Many scientists believe that greenhouse gases, such as carbon dioxide and methane, contribute to global warming. Many of them are released by burning fuels such as coal and oil.

    Companies will be required to buy permits for each ton of carbon they emit, although big polluting exporters will receive up to 90 percent of their carbon licenses free.

    Many business leaders want the government to delay the plan because of the current global financial crisis, which is slowing the Australian economy. Peter Anderson from the Australian Chamber of Commerce and Industry says it is irresponsible to bring in a carbon trading plan now.

    Environmentalists, on the other hand, say Prime Minister Kevin Rudd has not properly addressed the threat of climate change. Activists had sought a minimum emissions cut of 25 percent.

    Instead, the Rudd government aims to cuts carbon emissions by at least five percent of 2000 levels by 2020. That amount could rise to 15 percent, if future global agreements set such a target.

    Ray Nias of the environmental group WWF says Australia will pay the price for low targets. “This is a deeply, deeply disappointing target,” Nias said. “It commits Australia to long-term climate change. It will make Australia's ability to negotiate (协商) global agreements very, very difficult. It is much lower than even we had imagined.”

    Australia has one of the highest per-person greenhouse emissions rates in the world because of its reliance on coal for electricity.

    Some scientists warn that the vast, dry Australian continent, which has been suffering a series of droughts in recent years, could be one of the region's hardest hit by global warming.

    Raccoons are smaller relatives of bears. They are native to North America, but they can also be found in Asia and Europe. Raccoons live in wooded areas close to water, but they can be often found near urban areas. There are about 7 different species of raccoons. Pygmy raccoon is the only endangered species.

    Raccoons usually reach 40 to 70cm in length and weigh between 5­26kg. Raccoons that live in colder climates are larger and heavier. They have grayish fur, black masks around eyes and long tails covered with black and brown bands. Because of their tails, they are also called "ringtail".

    Raccoons are omnivores. They like to eat insects, eggs, small mammals, fruit, berries, garbage, and so on. Raccoon's hands look like human's. They each have five fingers and are used to collect food, open shells, door or trash cans. Raccoons often place food in water before they start to eat it. They have highly sensitive sense of touch and water increases their sensitivity even more. By touching the food, they get better insight about things they will eat.

    They are easily adaptable (适应的) to various environments. They can live in hollow (中空的) trees equally happily like they can in useless cars. Raccoons live on their own and hunt at night. They don't hibernate (冬眠), but they spend the coldest days of winters in their holes.

    Mating (交配) season takes place from January to mid March. Two months later, female will give birth to 3­4 babies. Their tails don't have bands, and the mask around eyes is still missing. Mother is very protective and she will teach them how to survive and what to eat as they become­ready to leave the hole. Raccoons usually can live only 1.8 to 3.1 years in the wild, but they can live up to 20 years at a zoo.

    Raccoons can pass rabies, a kind of disease, to home­raised animals and people, which is very dangerous. What's more, their waste often has roundworms.

    As we know, Julian Beever is an international well-known sidewalk chalk artist whose drawings have appeared on the streets of London, Buenos Aires, Paris, New York, and countless other cities around the world. Beever creates drawings that look completely three- dimensional when seen from the correct angle.

    Now, in his book, Pavement chalk artist: The three-dimensional drawings of Julian Beever, the artist shares some of his most fascinating and humorous pieces, Here are a few examples you'll find in the book.

   ●Philadelphia eagle

    In Pennsylvania, Beever created "Philadelphiaeagle" a huge drawing with an eagle landing successfully on an American national flag.

   ●Meeting Mr. Frog

    "Meeting Mr. Frog" was created in Salamanca, Spain, and is about a realistic-looking frog sitting on a Lily pad.

    Swimming pool in the high street

My personal favorite is "Swimming pool in the high street" from Brussels, which is about a woman relaxing in a swimming pool—--a swimming pool sunk into the middle of the street, that is!

    Along with an introduction about his background, Beever includes a description of the techniques he used and the challenges he overcame with every drawing. He shares information about his time at home in the UK. and abroad; there is a fun story to back up each piece of art.

    Beever's artwork is truly jaw dropping. You're sure to spend ages turning the leaves back and forth, surprised at how one man can create what looks like a three-dimensional design on a flat surface with just a bit of chalk. From animals to superheroes to famous buildings, the paintings are a wonder to lay eyes on.

    Payment chalk artist: The three-dimensional drawings of Julian Beever is surely worth a look. And another look. This 112-page hardcover book is available now from Firefly Books at a list price of $ 29.95

    Humans and elephants don't always get along. In Africa and Asia, elephants damage equipment, farmers' crops, and natural habitat for other species. If an elephant becomes a problem, humans may kill it. So local people and animal protectionists are trying to find better ways to keep elephants away from sensitive places. Now, researchers think they have a good tool to prevent elephants: honeybee pheromones (信息素).

    “Elephants dislike being stung(叮咬) in the trunk, because it's an extremely sensitive organ. Imagine being stung in your nose by a bee, and multiply that a few thousand times.” said Mark Wright, a professor at the University of Hawaii.

    Kenyan farmers have long known that if they hang live beehives (蜂箱) around their farms, they will drive elephants away. The problem is how to manage hundreds of thousands of hives, if you have a huge area to protect. And then the idea came up to look at the alarm pheromones, which are chemicals that the bees release to launch an attack on something that's damaging the hive.

    So the researchers tested out an artificial mixture of chemicals that imitates (模仿) honey bees' alarm pheromones. The researchers hung white socks treated with the artificial mixture as well as untreated control socks around an elephant watering hole, and then observed the animals' behavior. “Elephants are really curious creatures. They'll walk along and see something like a sock hanging on a branch. If it's not treated with the alarm pheromones, they'll pick it up, throw it around, and try to taste it, things like that. And in the case of the treated ones, they would show immediate signs of unease or uncertainty, and they'd eventually back off from them.”

    In order to avoid the elephants more effectively, the researchers plan to make the pheromone mixture purer. That way, elephants will stay far away from wherever they should not be going-and both elephants and humans can coexist a bit more peacefully.

Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father's wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.

"Dad will be really mad if he finds out you've been playing with his new computer." said, "He told us not to touch it."

"He won't find out," Mark said, "I'll just have a quick look and shut it down."

Mark had been scolded before for touching his father's equipment. But his curiosity was difficult to control and this new computer really puzzled him.

It was a strange-looking machine — one his dad had brought home from the laboratory where he worked. "It's an experimental model." his father had explained, "so don't touch it under any circumstances." But his father's warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later the screen turned into colours, shifting and changing, and then two big white words appeared in the centre of the screen: "SPACE TRANSPORTER."

"Yes!" Mark cried excitedly. "It's a computer game. I knew it! Dad's only been pretending to work. He's really been playing games instead!" A new message appeared on the screen:

"ENTER NAMES

VOYAGER 1:…

VOYAGER 2:…

Mark's fingers flew across the keyboard as he typed in both of their names.

"INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED. "

The screen turned even brighter and a noise suddenly rose in volume.

"I think we'd better shut it off, Mark," Jason yelled, reaching for the power switch. He was really frightened.

But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow, until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed:

"TRANSPORT SUCCESSFUL. DESTINATION: MARS. RETRIEVE DATE: 2025."
