Passage 1

Topic  Koalas

内容方面

A. Koalas are just too nice for their own good. And except for the occasional baby taken by

birds of prey, koalas have no natural enemies. In an ideal world, the life of an arboreal couch

potato would be perfectly safe and acceptable.

B. Just two hundred years ago, koalas flourished across Australia. Now they seem to be in

decline, but exact numbers are not available as the species would not seem to be 'under

threat'. Their problem, however, has been nan, more specifically, the white man. Koala and

aborigine had co-existed peacefully for centuries.

C. Today koalas are found only in scatered pockets of southeast Australia where they

seem to be at the risk on several fronts. The koala's only food source, the eucalyptus tree，

has declined. In the past 200 years, a third of Australia's eucalyptus forests have

disappeared. Koalas have been killed by parasites, chlamydia epidemics and a

tumour-causing retro-virus. And every year 11000 are killed by cars, ironically most of them

in wildlife sanctuaries, and thousands are klled by poachers. Some are also taken ilally

as pets. The animals usually soon die, but they are easily replaced.

D. Bush fires pose another threat. The horrific ones that raged in New South Wales recently

Killed between 100 and 1000 Koalas. Many that were taken into sanctuaries and shelters

were found to have burnt their paws on the glowing embers .But zoologists say that the

species should recover. The Koalas will be aided by the eucalyptus, which grows quickly

and is already burgeoning forth after the fires. So the main problem to their survival is their

slow reproductive rate - they produce only one baby a year over a reproductive lifespan of

about nine years.

E. The latest problem for the species is perhaps more insidious. With plush, grey fur, dark

amber eyes and button nose, koalas are cuddliness incamate Australian zo0s and wildlife

parks have taken advantage of their uncomplaining atitudes, and charge visitors to be

photogr aphed hugging the furry bundles. But people may not realise how cruel this is, but

because of the koala's delicate disposition, constant handling can push an already

precariously balanced physiology over the edge.

F. Koalas only eat the foliage of certain species of eucalyptus trees, between 600 and 1250

grams a day. The tough leaves are packed with cellulose ，tannins, aromatic oils and

precursors of toxic cyanides. To handle this cocktail, koalas have a specialised digestive

system. Cellulose-digesting bacteria in the caecum

break down fibre, while a specially

adapted gut and liver process the toxins. To digest their food property, koalas must sit still for

21 hours every day.

G. Koalas are the epitome of innocence and inoffensiveness. Although they are capable of

ripping open a man's arm with their needle-sharp claws, or giving a nasty nip, they simply

wouldn't. If you upset a koala, it may blink or swallow, or hiccup. But attack? No way! Koalas

are just not aggressive. "They use their claws to grip the hard smooth bark of eucalyptus

trees.

H. They are also very sensitive,. and the slightest upset can prevent them from breeding,

cause them to go off their food, and succumb to gut infections. Koalas are stoic creatures

and put on a brave face until they are at death's door. One day they may appear healthy, the

next they could be dead. Captive koalas have to be weighed daily to check that they are

feeding properly. A sudden loss of weight is usually the only warning keepers have that their

charge is il. Only two keepers plus a vet were allowed to handle London Zoo's koalas, as

these creatures are only comfortable with people they know. A request for the koala to be

taken to Beet the Queen was refused because of the distress this would have caused the

marsupial. Sadly. London's Zoo no longer has a koala. Two years ago the female koala died

of a cancer caused by a retrovirus. When they come into heat, female koalas become more

active, and start losing weight, but after about sixteen days, heat ends and the weight piles

back on. London' s koala did not. Surgery revealed hundreds of pea-sized tumours.

I. Almost every z00 in ; Australia has koalas-the marsupial has become the Animal

Ambass ador of the nation, but nowhere outside Australia would handling by the public be

allowed. Koala cuddling screams in the face of every rule of good care. First, some zoos

allow koalas to be passed from stranger to stranger, many children who love to squeeze.

Secondly, most people have no idea of how to handle the animals: they like to cling on to

their handler, all in their own good fime and use his or her arm as a tree. For such reasons,

the Association of Fauna and Marine parks, an Australian conservation society is

campaigning to ban koala cuddling. Policy on koala handling is determined by state

goverment authorities. "And the largest of the numbers in the Australian nature

Conservation Agengy, with the aim of instituting national guidelines. Following a wave of

publicity, some z00S and wildlife parks have stopped tuming their koalas into photo.
