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

Affected by habitat (栖居地) 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 (给注射疫苗)  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.

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.

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

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

4.It can be inferred from the text that________.

A. a 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

In many situations, the quality of your travel experience is directly affected by your ability to understand the local language. For some travelers, the challenge of learning a new tongue is one of the joys of travel, and as a result, they spend much of their time in conversations with local citizens. Others will find that just learning to read the most common signs and use every-day greetings is enough.

No matter which view you agree with, it’s necessary to take some time to learn some of the simple phrases of the new language before you go. One way of finishing this task is by listening to the new language. A phrase book can help expand your vocabulary, but hearing the sounds of the different spoken words is an excellent activity that can be done right in the comfort of your home. You can see movies in the new language or listen to the tapes or CDs. You can also download some listening material from the Internet. Just spending 15 minutes a night will improve your language skills.

When you arrive in the new land, begin by greeting new friends in their own tongue. This may come easy or it could take some time to learn, but it’s interesting. If you can’t do this, then it means that you will need more practice and patience to learn these very important words. You can go out during the day and begin one-on-one conversations with shop owners, business-men and taxi drivers. This should not be done until you have learned some of the most common phrases, but once you begin to go shopping in a second language your communication skills will start to improve rapidly.　　　 You can also watch the local TV or listen to the local radio. For example, the advertisements will help you recognize the correct pronunciation of local street names.

Success is often measured by the ability to overcome adversity. But, it is often the belief of others that gives us the courage to try.

J. K.　 Rowling, author of the Harry Potter book series，began writing at the age of 6. In her biography, she remembers　 with great fondness when her good friend Sean, whom she met in secondary school, became the first person to encourage her and help build the confidence that one day she would be a very good writer.

“He was the first person with whom I really discussed my serious ambition to be a writer.　 He was also the only person who thought I was bound to be a success at it, which meant much more to me than I ever told him at the time.”

Despite　 many　 setbacks,　 Rowling　 persevered　 in　 her writing, particularly fantasy stories.　 But it wasn't until 1990 that she first conceived the idea about Harry Potter.　 As she recalls，it was on a long train journey from London to Manchester that the idea of Harry Potter simply fell into her head.“To my immense frustration (沮丧), I didn't have a functioning pen with me, and I was too shy to ask anybody if I could borrow one. I think, now, that this was probably a good thing, because I simply sat and thought, for four (delayed train) hours, and all the details bubbled up in my brain, and this scrawny, black­haired, bespectacled(戴眼镜的) boy who didn’t know he was a wizard became more and more real to me.”

That same year, her mother passed away after a ten­year battle with　 multiple　 sclerosis,　 which　 deeply　 affected　 her writing.　 She went on to marry and had a daughter, but separated from her husband shortly afterwards.

During this time, Rowling was diagnosed with clinical depression. Unemployed, she completed her first novel in area cafes, where she could get her daughter to fall asleep. After being rejected by 12 publishing houses, the first Harry Potter novel was sold to a small British publishing house.

Now with seven books that have sold nearly 400 million copies in 64 languages, J. K. Rowling is the highest earning novelist in history.　 And it all began with her commitment to writing that was fostered by the confidence of a friend !
