【2017全国Ⅲ卷】After years of heated debate, gray wolves were reintroduced to Yellowstone National Park. Fourteen wolves were caught in Canada and transported to the park. By last year, the Yellowstone wolf population had grown to more than 170 wolves.

   Gray wolves once were seen here and there in the Yellowstone area and much of the continental United States, but they were gradually displaced by human development. By the 1920s, wolves had practically disappeared from the Yellowstone area. They went farther north into the deep forests of Canada, where there were fewer humans around.

   The disappearance of the wolves had many unexpected results. Deer and elk populations — major food sources (来源) for the wolf — grew rapidly. These animals consumed large amounts of vegetation (植被), which reduced plant diversity in the park. In the absence of wolves, coyote populations also grew quickly. The coyotes killed a large percentage of the park’s red foxes, and completely drove away the park’s beavers.

   As early as 1966, biologists asked the government to consider reintroducing wolves to Yellowstone Park. They hoped that wolves would be able to control the elk and coyote problems. Many farmers opposed the plan because they feared that wolves would kill their farm animals or pets.

   The government spent nearly 30 years coming up with a plan to reintroduce the wolvers. The U.S. Fish and Wildlife Service carefully monitors and manages the wolf packs in Yellowstone. Today, the debate continues over how well the gray wolf is fitting in at Yellowstone. Elk, deer, and coyote populations are down, while beavers and red foxes have made a comeback. The Yellowstone wolf project has been a valuable experiment to help biologists decide whether to reintroduce wolves to other parts of the country as well.

1. What is the text mainly about?

A. Wildlife research in the United States.

B. Plant diversity in the Yellowstone area.

C. The conflict between farmers and gray wolves.

D. The reintroduction of wolves to Yellowstone Park.

2. What does the underlined word “displaced” in paragraph 2 mean?

A. Tested.   B. Separated.   C. Forced out.   D. Tracked down.

3. What did the disappearance of gray wolves bring about?

A. Damage to local ecology.         B. A decline in the park’s income.

C. Preservation of vegetation.        D. An increase in the variety of animals.

4. What is the author’s attitude towards the Yellowstone wolf project?

A. Doubtful.        B. Positive.     C. Disapproving.     D. Uncaring.

【2017全国I卷】 I work with Volunteers for Wildlife, a rescue and education organization at Bailey Arboretum in Locust Valley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.

   I got a rescue call from a woman in Muttontown. She had found a young owl(猫头鹰) on the ground. When I arrived, I saw a 2-to 3-week-old owl. It had already been placed in a carrier for safety.

   I examined the chick(雏鸟) and it seemed fine. If I could locate the nest, I might have been able to put it back, but no luck. My next work was to construct a nest and anchor it in a tree.

   The homeowner was very helpful. A wire basket was found. I put some pine branches into the basket to make this nest safe and comfortable. I placed the chick in the nest, and it quickly calmed down.

   Now all that was needed were the parents, but they were absent. I gave the homeowner a recording of the hunger screams of owl chicks. These advertise the presence of chicks to adults; they might also encourage our chick to start calling as well. I gave the owner as much information as possible and headed home to see what news the night might bring.

   A nervous night to be sure, but sometimes the spirits of nature smile on us all! The homeowner called to say that the parents had responded to the recordings. I drove over and saw the chick in the nest looking healthy and active. And it was accompanied in the nest by the greatest sight of all — LUNCH! The parents had done their duty and would probably continue to do so.

5. What is unavoidable in the author’s rescue work according to paragraph 1?

A. Efforts made in vain.      B. Getting injured in his work.

C. Feeling uncertain about his future.   D. Creatures forced out of their homes.

6. Why was the author called to Muttontown?

A. To rescue a woman.      B. To take care of a woman.

C. To look at a baby owl.      D. To cure a young owl.

7. What made the chick ca lm down?

A. A new nest.  B. Some food.   C. A recording.   D. Its parents.

8. How would the author feel about the outcome of the event?

A. It’s unexpected.       B. It’s beautiful.

C. It’s humorous.        D. It’s discouraging.

【2019武汉市高中毕业生四月调研测试】While elephants born without tusks (长牙)are not unheard-of, they normally form just 2 to 6 per cent of the population. However, that is not the case at Mozambique’s Gorongosa National Park, where an astonishing 33 per cent of female elephants born after the country’s civil war ended in 1992 are tuskless. While that may appear to be just a coincidence, Joyce Poole, an elephant behaviour expert, has another theory. The researcher thinks we may be witnessing unnatural evolution of the species due to the constant hunting of elephants for valuable ivory.

   Poole says before the country’s 15-year-long civil war, the 100,000-acre park was home to over 4,000 elephants. However, by the time the conflict ended in 1992, about 90 per cent of them had been killed for ivory to help finance weapons (武器)and meat to feed the soldiers. Of the less than 200 survivors, over 50 per cent of adult females had no tusks. Therefore, it is not surprising that the park’s tuskless elephant population has grown greatly.

   This is not the first time researchers have observed a great change in the population of elephants. At Zambia’s South Luangwa National Park and Lupande Game Management Area, areas which were heavily hunted in the 1970s and 1980s, 35% of elephants 25 years or older and 13% of those younger than 25 are now without tusks. A study published in 2008 found that the number of tuskless females at the Ruaha National Park in Tanzania went from 10.5 per cent in 1969 to almost 40 per cent in 1989, largely due to illegal hunting for ivory.

   The recent ban on ivory in both the US and China should help get rid of, or at least reduce, elephant hunting. However, scientists are not sure how long it will take for elephants with a higher rate of tuskless females, to change the trend.

9. What is the probable cause of the phenomenon mentioned in Paragraph 1 ?

A. Illegal hunting.      B. Constant farming.

C. A pure coincidence.     D. Natural evolution.

10. Why did people kill so many elephants during the civil war in Mozambique?

A. To get funds by selling ivory.   B. To develop new weapons.

C. To provide food for local people.  D. To make ivory products.

11. Which of the following had the earliest record on tuskless elephants?

A. Gorongosa National Park.    B. South Luangwa National Park.

C. The Ruaha National Park.    D. Lupande Game Management Area.

12. What does the underlined phrase “the trend” in the last paragraph refer to?

A. Elephants facing greater danger.  B. Elephants growing more slowly.

C. Fewer female elephants staying alive. D. More female elephants being tuskless.

【2020陕西省部分学校第一学期摸底检测】A biologist once criticized for stealing eggs from the nests of the rarest bird in the world has been awarded the “Nobel Prize” of conservation after his methods saved nine species from extinction.

   Professor Carl Jones won the 2016 Indianapolis Prize — the highest accolade in the field of animal conservation — for his 40 years of work in Mauritius, where he saved an endangered kestrel (红隼) from becoming the next Great Auk.

   When the 65-year-old first travelled to the east African island in the 1970s, he was told to close down a project to save the Mauritius kestrel. At the time there were just four left in the wild, making it the rarest bird on Earth. However, he stayed, using the techniques of captive breeding (人工繁殖), which involved snatching eggs from the birds’ nests and hatching them under incubators(孵化器), prompting the mothers to lay another set of eggs in the wild.

   A decade later, the number of Mauritius kestrels had soared to over 300 and today there are around 400 in the wild.  The biologist has also made an effort to bring other rare species back from the edge of extinction, including the pink pigeon, echo parakeet and Rodrigues warbler.

Prof Jones was awarded the $250,000 prize at a ceremony in London.

   “As a young man in my 20s, I certainly didn’t enjoy the stress and the tension of the criticism I received.” Reflecting on the start of his career, he said the Mauritius kestrel project had been seen as a “dead loss” at the time. In the 1970s there was fierce opposition to the captive breeding techniques, with critics arguing that they were too risky and took the emphasis off breeding in the wild.

Prof Jones has devoted his whole life to his work, only becoming a father for the first time at 53. He said receiving the prize was particularly important to him, because it proved that his work to save birds was right.

13. According to the passage, Great Auk is ________.

A. an endangered bird     B. an extinct bird 

C. a popular bird           D. a fierce bird

14. What can we know from the figures in Paragraph 4?

A. Taking eggs from the nests has worked well.

B. The wild environment for kestrel has changed a lot.

C. Kestrel has adapted to the life in the wild.

D. It’s difficult to protect kestrel.

15. Prof Jones’ idea of taking eggs from the birds’ nests ________.

A. was proved of no use    B. was widely accepted

C. was promoted officially   D. was criticized by some people

【2019全国卷I】 The polar bear is found in the Arctic Circle and some big land masses as far south as Newfoundland. While they are rare north of 88°, there is evidence    31    they range all the way across the Arctic, and as far south as James Bay in Canada. It is difficult to figure out a global population of polar bears as much of the range has been     32    (poor) studied; however, biologists calculate that there are about 20,000-25,000 polar bears worldwide.

Modem methods   33   tracking polar bear populations have been employed only since the mid-1980s, and are expensive   34   (perform) consistently over a large area. In recent years some Inuit people in Nunayut   35   (report) increases in bear sightings around human settlements, leading to a   36   (believe) that populations are increasing. Scientists have responded by   37   (note) that hungry bears may be congregating(聚集) around human settlements, leading to the illusion(错觉) that populations are   38   (high) than they actually are. Of   39   nineteen recognized polar bear subpopulations, three are declining, six   40   (be) stable, one is increasing, and nine lack enough data.
