Koalas are pictured everywhere in Australia-on cleaning products, on “boxes of chocolate, on sports team shirts. Yet the animals live only in pockets along the east coast.

They once inhabited the entire coastline. The koala population dropped after farmers cut down many of the forests where koalas lived, and hunters killed the animals for their fur.

By the early 1900s, “koalas were basically shot out of south Australia,” says ecologist Bill Ellis, who studies the relationships among living things and their environments.

I recently joined Ellis and his team in a forest on St Bees Is land, 19 miles off the northeastern coast of Australia, with eight other volunteers. The island is a natural laboratory, yielding findings that may help protect koalas elsewhere on the continent.

The volunteers searched the island for koalas in the blue gum trees. When we found a koala, we gathered information about the trees in the area.

Blue gum is a species of the eucalyptus tree in which the funny leaf eaters spend most of their time. Eucalyptus trees are native to Australia, and their leaves are the main food source for koalas. Although koalas can walk on the ground, they are better suited for life in the canopy, the high cover of branches and leaves in a forest.

What has Ellis’s research told him so far? The population of St Bees seems to be healthy. Yet Ellis wonders whether the koalas might be heading for hard times. The island is overrun with wild goats, and Ellis thinks the goats are eating the small blue gum trees.

Without those trees, the koalas will run out of food in the future. Ellis hopes more research will help him understand how to protect the blue gum trees-and the koalas that depend on them. “I think that’s what everyone is trying to do-to make a difference.” Ellis says.

         C. To find some new foods for goats.

讀寫任務(wù)（共1小題，滿分25分）

閱讀下面的短文，然后按照要求寫一篇150詞左右的英語(yǔ)短文。

Jackie is perhaps the most easily annoyed koala（考拉）at the Featherdale Wildlife Park in southern Australia. All the koalas there are unhappy and complaining. You would be too if you were used to night activities and someone kept waking you up all day while you were trying to sleep it off. That’s right—sleep it off. The average koala is always half asleep because it feeds on the leaves of a special kind that makes it sleepy.

The reason Jackie and her fellow koalas are repeatedly awoken from their deep sleep is so they can be hugged and photographed by tourists，who make the trips to Featherdale and an increasing number of other national parks for just that special experience. Whatever department in the Aussie government in charge of such things is now moving to make the practice illegal，which is understandable. How would you react，my friend，if you were trying to sleep off a dozen times and some round，furry creature smelling of grass kept waking you?

Their round bodies, round flat noses and large ears often remind us of bears every time we see koalas. Probably that’s why these animals are often referred to as koala bears. Koalas are natives of Australia. However, they aren’t found all over the continent. The habitat of koala bears spans (橫越) over eastern regions of Australia that include states like Queensland, New South Wales and Victoria and also in the state of South Australia.

   Koalas are found where are enough forests of eucalyptus(桉樹(shù)) trees. The association of koalas and eucalyptus trees is due to the fact that these animals feed on the leaves of eucalyptus trees. But that’s not all. In addition, the trees also serve as the homes of the koalas.

   Koalas grow around 27 to 36 inches tall and weigh 5 to 9 kilograms on average. Male kaolas are larger than the females. Life expectancy can stretch up to 17 years.

   Like many other animals, the habitat of koala bears is fast decreasing due to deforestation and quick urbanization(都市化). However,efforts by some scientists and animal lovers have successfully introduced these creatures back in certain parts of Australia.

The koala, one of Australia’s most treasured creatures, is in trouble.

Affected by habitat (棲居地) loss and climate change, like many other uniquely Australian animals, koalas are being squeezed into smaller regions. But at present, it is a deadly disease, a somewhat silent killer that causes a further decline in the koala population, that is worrying many scientists about the fate of the koala.
The killer is Chlamydia, which has caused symptoms in up to 50 percent of the wild koalas, with probably even more infected (感染) but not showing symptoms. It has been particularly severe in Queensland, where nearly all koalas are infected. The disease causes many symptoms including eye infections, which can lead to blindness, making it difficult for them to find their primary food.
Treating Chlamydia in wild koalas is a challenge. There is no treatment available for it. Only a small percentage of the animals can be treated successfully and returned to the wild. Besides, there is no national plan in Australia to save the koala; it is up to each region to make management plans for its koala population.
The good news is that researchers are working to test a vaccine (疫苗) that would help prevent further spread. If all goes well, plans can be carried out to distribute the vaccine more widely. But it’s impossible to vaccinate (給注射疫苗)  all wild koalas.
Another possibility would be to make vaccine distribution a routine part of treatment for the thousands of koalas brought into care centers every year after they are injured by cars or dogs.
While it is a combination of problems that are affecting the wild koala population, many experts believe this vaccine would be an important step in helping koalas survive longer. It may be enough time to give researchers a chance to solve some of the other problems facing Austalia’s koalas.
【小題1】Which isn’t considered the main cause of koala’s population decline?

A．A deadly disease.
B．Injuries from cars and dogs.
C．Climate change.
D．Habitat loss.
【小題2】The third paragraph mainly tells us         .
A．the serious result Chlamydia has caused to the koala
B．Chlamydia affected the koala only in particular regions
C．the most serious symptom of Chlamydia is eye infections
D．Chlamydia can seriously affect koala’s primary food
【小題3】We can learn from the text that the vaccine      .
A．would cure the killer Chlamydia quite effectively
B．would only be distributed in koala care centers
C．has already been put into practical use in Australia
D．cannot be distributed to all the infected koalas
【小題4】It can be inferred from the text that        .
A．a(chǎn) national plan for saving koalas will be made soon in Australia
B．koala population is declining only in a few regions
C．researchers need enough time to solve the koala problems
D．experts have lost the best chance to save the infected koalas
