📖 课文原文 · Racing to Rescue Koalas
Paragraph A
It's 2 in the morning, and a koala is caught on a fence, like a prisoner trying to escape.
A phone rings in the home of Meghan Akin in a suburb of Brisbane, on the east coast of Australia.
Akin runs a volunteer organization devoted to rescuing wild koalors.
Before she has told the location, she has already thrown her clothes over her pajamas ready to head out.
When eight can arrive on the scene, two other volunteers, Jane Davies, and Sandra Peachy are already there.
Paragraph B
They discover that the koalors fur is caught in the barbed wire.
Nearby, they notice tall eucalyptus trees.
He was obviously trying to get to the trees on the other side, Akin says.
Eight can put on heavy gloves.
Despite their cuter parents, koalors can be ferocious when resisting capture.
If they feel threatened, they bite, and Akin has the scars to prove it.
The volunteers get to work.
Davies throws a blanket over the animal, while Peachy opens the lid of a cage.
Akin firmly grasps the koala through the blanket, frees it from the fence, and drops it in the cage.
Paragraph C
Next, they check the animal's physical condition.
If the koala is sick or injured, it may need to be taken to an animal hospital.
If the koala is healthy, like this one, it is normally released where it is found.
Koalors tend to live in a small area, and often eat from the same trees over and over.
Right now, however, Akin and the rescued koala are in a suburb with almost no trees.
Paragraph D
This is the whole problem, Akin says.
There are so few places left for the koala.
In the end, Akin takes the animal to a small park nearby and releases him.
Good luck, little one.
She says.
Koalors at risk.
Koalors are getting caught in fences and dying.
Explains deirdre de Villiers, a koala research in Queensland, Australia.
Paragraph E
Others are being killed by dogs or struck by vehicles.
She says.
Some even die, simply because a homeowner cut down several eucalyptus trees in his backyard.
For 15 years, De Villiers has been studying koalors and the reasons for their disappearance.
She is also working on ways to make suburban areas more koala friendly.
Paragraph F
De Villiers believes that koalors and humans can live together, if certain changes are made.
She recommends reducing speed limits on streets and creating more green areas for koalors to live in.
Even more important is the need to preserve eucalyptus trees.
Even if these changes are made, koalors still have another problem.
Paragraph G
Disease is a huge issue, explains veterinarian John Hanger.
Hanger says that almost half of Queensland's female koalors are affected by a disease called Climideosis.
Without treatment, the koalors are unable to reproduce.
Koala populations that used to be vibrant are becoming extinct, says Hanger.
Once there were millions of koalors in Australia, now there are believed to be fewer than 80,000.
Paragraph H
A friend to koalors.
At her home, Nibrisman, Deirdre de Villiers is taking care of a female koala named Ruby.
Ruby still sleeps in the basket hugging her teddy bear, she says.
She was rescued from the jaws of a dog.
Every two days, De Villiers collects eucalyptus leaves, the koalors primary food from a nearby farm to feed Ruby.
For 12 years, she has cared for more than 60 koalors.
Paragraph I
Later, De Villiers visits a forest near Brisbane to catch TV, a wild female koala.
De Villiers has been following TV for over a year.
Using special audio equipment, De Villiers walks and listens for a signal from the koala's radio collar.
She eventually finds TV sitting on a tree branch 15m high.
As De Villiers climbs up a ladder, TV starts moving down the tree.
Paragraph J
Then suddenly, the koala jumps into the air and lands on the ground.
She is quickly captured by De Villiers team.
TV is given medicine to relaxer.
Next, De Villiers measures the length of the koala's body and head.
She also checks TV's teeth and the condition of her fur.
I think she has a baby, De Villiers says.
She carefully opens up the koalors pouch and takes out a 10cm long baby koala.
Paragraph K
De Villiers examines the baby for any problems.
Then, she puts it back in the mother's pouch.
As long as there are healthy babies, she says, they're still hope.
Losing their eucalyptus.
Over two centuries ago, about 10 million koalors lived in forests on the east coast of Australia.
Paragraph L
Eucalyptus leaves, their primary food source were plentiful.
By the start of this century, nearly two-thirds of the forests had been cleared, living fewer than 80,000 koalors left in the wild.
