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 vaccil1e more widely. But it"s impossible to vaccinate all wild koalas.
Another possibility would be to make vaccine distribution a routi11e 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 expects believe this vaccine would be an important step in helping koalas survive longer. It may buy enough time to give researchers a chance to solve some of the other problems facing Australia"s koalas.
B. Injuries from cars and dogs.
C. Climate change.
D. Habitat loss.
B. Chlamydia affected the koala only in particular regions
C. the most serious symptom of Chlamydia is eye infections
D. Chla1nydia can seriously affect koala"s primary food
B. Chlamydia
C. national plan
D. eye infection
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
B. koala population is declining only in a few regions
C. researchers need enough time to so1ve the koala problems
D. experts have lost the best chance to save the infected koalas

Imagine living on the edge of a vast desert, which is moving quietly closer to your village every day
and covering your fields. The desert is on the move. This is called desertification.
Desertification occurs in regions close to an already existing desert. 1 The first is over-use of
water in the area. There is not enough water in any case, and if it is not carefully used, disaster can follow. As time goes on, water shortages make farming more and more difficult. In some places, locals can
remember local lakes and marshes which were once the homes for all kinds of fish and birds. 2
Farmers leave the land, and fields are replaced by deserts.
The second cause is misuse or over-use of the land. 3 Ploughing(耕) large fields and removing
bushes and trees means that the wind will blow away the soil. Once the soil is lost, it is hard to replace,
and if there is rain, it has nowhere to go, and brings no benefit.
4 Every spring, the skies over some of eastern cities, thousands of kilometers away from the
deserts, can be darkened by sandstorms. Dust from deserts can have a great effect on weather systems. While desertification is perhaps being partly caused by global warming, these sandstorms can make
global warming worse by adding to what is known as the greenhouse effect.
What can be done to slow down or stop the process of desertification? A great deal of work is
already under way. Obviously first steps are to find new water sources. 5 Some types of grass also
hold the soil together, and stop the wind taking it. Without these efforts, it will be harder and harder to
stop the world"s deserts in their tracks, and more and more farmers will give up and head for cities. The
lesson to be learnt lies beneath the sand.
| A. It generally arises from two related causes. B. It is not only the farmers and villagers who suffer. C. They have been completely buried by the sand now. D. Scientists are doing the research on the cause of desertification. E. They destroy the land, as the soil dries out and is then blown away. F. Tree planting can help, by providing barriers between desert and rich field. G. This means that the wrong crops are planted, and need more water than is available. |

| Beijing had its biggest snowfall since 1951. Britain is suffering through its longest cold snap (寒潮) since 1981. And freezing weather is hitting the Deep South, including Florida"s orange groves and beaches. Whatever happened to global warming? Such weather doesn"t seem to fit with warnings from scientists that the Earth is warming because of greenhouse gases. But experts say the cold snap doesn"t contradict global warming at all - it"s just a temporary phenomenon in the long-term heating trend. "It"s part of natural variability," said Gerald Meehl, a senior scientist. With global warming, he said, "we"ll still have record and cold temperatures. We"ll just have fewer of them." Scientists say man-made climate change does have the potential to cause more frequent and more severe weather extremes. But experts did not connect the current cold snap to climate change. So what is going on? "We basically have seen just a big outbreak of Arctic air over populated areas of the Northern Hemisphere", Arndt said. In the atmosphere, large rivers of air travel roughly west to east around the globe between the Arctic and the tropics. This air flow acts like a fence to keep Arctic air restricted. But recently, this air flow has become bent into a zigzag (之字形) pattern, wandering north and south. If you live in a place where it brings air up from the south, you get warm weather. In fact, record highs were reported this week in Washington state and Alaska. But in the eastern United States, like some other unlucky parts of the globe, Arctic air is coming from the north. And that"s how you get a temperature of 3 degrees in Beijing, a reading of minus-42 in mainland Norway, and 18 inches of snow in parts of Britain. The zigzag pattern arises naturally from time to time, but it is not clear why it"s so strong right now. |
| 1. What is the main idea of the text? |
| A. Freezing weather is hitting the Deep South. B. We"ll still have record cold temperatures. C. The air flow has become a zigzag pattern. D. Cold snap doesn"t contradict global warming. |
| 2. With global warming, we will ____. |
| A. also meet with severe cold snap B. have more hot temperatures forever C. never experience cold temperatures D. have more cold temperatures |
| 3. Beijing had its biggest snowfall since 1951 because of ____. |
| A. a fence from the Arctic B. a cooling trend in climate C. a big outbreak of Arctic air D. its large population |
| 4. We can conclude that ____. |
| A. not all the parts of the Northern Hemisphere are cold in face of the cold snap B. the zigzag pattern arises naturally accidentally C. Beijing will get cold weather next year D. Washington state and Alaska will not face cold weather next year. |

| Doctors say anger can be an extremely damaging emotion, unless you learn how to deal with it. They warn that anger can lead to heart disease, stomach problems, headaches, emotional problems and possibly cancer. __1 _ Some people express anger openly in a calm reasonable way. Others burst with anger, and scream and yell. But other people keep their anger inside. They cannot or will not express it. This is called repressing anger. For years many doctors thought that repressing anger was more dangerous to a person"s health than expressing it. They said that when a person is angry, the brain release the same hormones (荷尔蒙). They speed the heart rate, raise blood pressure, or sugar into the blood, etc. __2__ Some doctors say that both repressing and expressing anger can be dangerous. They believed that those who express anger violently may be more likely to develop heart disease, and they believe that those who keep anger inside may face a greater danger of high blood of pressure. __3__ They say the first step is to admit that you are angry and recognize the real cause of the anger, then decide if the cause is serious enough and get angry about. If it is, they say, " 4 . Wait until your anger has cooled down and you are able to express yourself calmly and reasonably." Doctors say that a good way to deal with anger is to find humor in the situation that has made you angry. __5__ |
