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.

It is easy to find your way about in New York. It is laid out so regularly. Instead of streets winding and twisting (迂回) as they do in London, they are all regular and well planned. The streets running north and south are called “avenues” and are numbered, e.g. 1st Avenue, 2nd Avenue, etc. The streets going east and west are called “streets” and are also numbered, e.g. 51st Street, 63rd Street. It is all much more logical (合理的) than London’s street names. But I couldn’t help thinking how much more interesting than these dull cold numbers are London’s illogical but colorful names of streets, e.g. “Bishopgate” (which is not a gate and hasn’t a Bishop in it); “Haymarket” or “Corn market” (where you won’t see any hey or corn) or “Poultry” (without a living chicken anywhere in sight) or “Thread needle Street” (where you won’t find little girls learning to sew).
【小题1】In the second sentence of the passage, “laid out” means ______.
A.built | B.be put | C.designed | D.cut down |
A.avenues in London | B.streets in America |
C.avenues in New York | D.streets in London |
A.avenues and streets are the same |
B.streets in America are better than avenues in England |
C.streets in New York are better than those in London |
D.the writer didn’t agree with the London streets planners |
A.are quite good | B.are interesting |
C.are not practical | D.differ greatly in form |
A.London streets | B.New York streets |
C.both | D.neither |
Daniel stays home on workdays. He starts his personal computer in order to connect with the office which is about three hundred miles away in another city. After work, he puts on his headphones, watches a movie on his home video recorder, or plays baseball on the computer. On many days, Daniel doesn’t talk to any other human beings, and he doesn’t see any people except the ones on television. Daniel is imaginary, but his lifestyle is very possible. The inventions of modern technology seem to be cutting us off from contact with our fellow human beings.
The world of business is one area in which technology is separating us. Experts say, for example, that many people will soon be able to work at home. With access to a large central computer, employees such as office clerks, insurance agents, and accountants could do their jobs at display terminals (终端) in their own homes. They would never have to actually see the people they’re dealing with. In addition, the way employees are paid will change. Workers’ salaries will be automatically paid into their bank accounts, making paper checks unnecessary. No workers will stand in line to receive their pay or cash their checks. Personal banking will change, too. Customers will deal with machines to put in or take out money from their accounts. Many companies and consumers have already changed the way they sell or buy products. E-commerce, or business done on the Internet, is becoming more and more popular. This, therefore, makes it possible for people to do shopping without going out of their homes.
Another area that technology is changing is entertainment. Music, for example, was once a group experience. People listened to music at concert halls or in small social gatherings. For many people now, however, music is an individual experience. Walking along the street or sitting in their living-rooms, they wear headphones to build a wall of music around them. Movie entertainment is changing as well. Movies used to be social events. Now, fewer people are going out to see a movie. Many more are choosing to wait for a film to appear on television or are borrowing videotapes to watch at home. Instead of laughing with others, viewers watch movies in their own living-rooms.
