A
Imagine a world with no more wild animals: no elephants, no tigers or lions. To some people, that thought is too terrible for words. So they are doing something about it. Tiffany Soechting is one of them.
Being among wild animals—feeding them and caring for them—is all Tiffany Soechting wants to do with her life. And that is exactly what she has done!
Soechting is the human “mother” to the 500 animals that live on her family wildlife farm in San Antonio. Besides her animal caring, Soechting also holds monthly classes, where she teaches school children about the animals.
Soechting also opens the farm to the public. Visitors can not only learn about the animals, but also get close to them. And the animals are not against that. For them, people are part of their natural environment.
The farm is part of conservation area, part of educational centre and part of animal park. As the animals walk peacefully around the grounds, it is easy for them to forget that San Antonio, a busy city, is just a few minutes away.
1. What’s implied in the sentence “Soechting is the human ‘mother’ to the 500 animals”?
A. She has already married and has some children.
B. The animals on the farm are taken good care of.
C. The animals can get along well with each other.
D. She teaches school children about animals well.
解析:推理判断题。通过这句话可以看出泽希廷把这些动物当作自己的孩子来看待。由此可知,这些动物得到了很好的照顾。故选B。
答案:B
2. What kind of person is Soechting according to the text?
A. Confident but lazy.
B. Humorous and lovely.
C. Wise but careless.
D. Kind and hard-working.
解析:推理判断题。通过泽希廷照顾动物可以看出她很善良;从她保护动物的具体行为可以看出她很勤劳。故选D。
答案:D
3. What’s the best title of the text?
A. How to Save Wild Animals
B. Soechting and Her Wild Animals
C. San Antonio’s Animal Park
D. A World Without Wild Animals
解析:标题归纳题。本文主要讲述了泽希廷致力于保护野生动物的故事,文章主体是泽希廷和野生动物。故选B。
答案:B
B
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.
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.
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. The government spent nearly 30 years coming up with a plan to reintroduce the wolves. The US Fish and Wildlife Service carefully monitors and manages the wolf packs in 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.
4. 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 gray wolves to Yellowstone Park.
解析:主旨大意题。根据第一段第一句“... gray wolves were reintroduced to Yellowstone National Park.”和最后一段第二句“The government spent nearly 30 years coming up with a plan to reintroduce the wolves.”可知,文章主要介绍了黄石公园当地政府重新引进灰狼的计划。故选D。
答案:D

5. What does the underlined word “displaced” in paragraph 2 mean?
A. Tested.　　　　　
B. Separated.
C. Forced out.
D. Tracked down.
解析:词义猜测题。根据第二段内容可知,在黄石国家公园,灰狼曾经随处可见,但是到了20世纪20年代,由于人类活动频繁导致灰狼基本消失,由此可以推测,灰狼因为人类的发展而被迫离开。force out 意为“赶出去”,与displace 意思相近。故选C。
答案:C
6. 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.
解析:细节理解题。根据第三段内容可知,灰狼的减少造成了鹿群的增多,从而导致植被遭到了破坏,而且红狐和海狸也不断减少,由此推断,灰狼的消失对当地生态系统造成了破坏。故选A。
答案:A
7. What is the author’s attitude towards the Yellowstone wolf project?
A. Doubtful. B. Positive.
C. Disapproving. D. Uncaring.
解析:观点态度题。根据文章末段末句可知,作者认为引进灰狼的项目是很有价值的实验,是很值得推广的。故选B。
答案:B
C
The sixth mass extinction of life on the earth is unfolding more quickly than expected, scientists have warned. More than 30 percent of animals with a backbone are declining in both range and population, according to the first comprehensive analysis of these trends.
Around a decade ago, experts feared that a new range wipeout of species was appearing. Today, most agree that it is underway, but the new study suggests that the die-out is already growing fast.
The loss of biodiversity has recently accelerated. Several species of mammals that were relatively safe one or two decades ago are now endangered, including cheetahs, lions and giraffes, the study showed.
There is no mystery as to why: our own ever-expanding species—which has more than doubled in number since 1960 to 7.4 billion—is eating, crowding and polluting its planetary cohabitants out of existence. By comparison, there are as few as 20,000 lions left in the wild, less than 7,000 cheetahs, 500 to 1,000 giant pandas.
The main drivers of wildlife decline are habitat loss, over-consumption, pollution, other species, disease, as well as hunting in the case of tigers, elephants, rhinos and other large animals prized for their body parts.
Climate change is thought to become a major threat in the coming decades, with some animals—most famously polar bears—already in decline due to rising temperatures and changing weather patterns.
8. What does the underlined word “accelerated” in paragraph 3 mean?
A. Made up. B. Put up.
C. Sped up. D. Used up.
解析:词义猜测题。根据画线词下文“Several species of mammals that were relatively safe one or two decades ago are now endangered, including cheetahs, lions and giraffes, the study showed.”可知,研究显示,包括猎豹、狮子以及长颈鹿在内的数种哺乳动物在一二十年前还相对安全,然而现在处于濒危状态。因此推断,画线词所在句句意为:生物多样性的减少最近也加速了。故画线词与C项“加速”词义相近。故选C。
答案:C
9. Why has the loss of biodiversity sped up?
A. The mankind’s population is growing fast.
B. The air pollution is too severe.
C. There are fewer species in larger areas.
D. Man causes wider water pollution.
解析:细节理解题。根据第四段第一句“There is no mystery as to why: our own ever-expanding species—which has more than doubled in number since 1960 to 7.4 billion—is eating, crowding and polluting its planetary cohabitants out of existence.”可知,引发生物大灭绝的原因显而易见:人类不断繁衍壮大,人口达到74亿,相比1960年不止翻了一番。人们以动物为食,同时还污染环境,让其他动物们无法生存。由此可知,人口的快速增长是生物多样性减少的原因。故选A。
答案:A
10. How is the future of polar bears?
A. Uncertain. B. Hopeful.
C. Doubtful. D. Unsatisfying.
解析:推理判断题。根据最后一段中的“with some animals—most famously polar bears—already in decline due to rising temperatures and changing weather patterns”可知,气候变化在未来的几十年将成为生物灭绝的主要因素。由于气温升高,气候变化,一些动物,比如最著名的北极熊,已经在减少。因此推断,北极熊的未来是令人不满意的。故选D。
答案:D
11. What is the main idea of the text?
A. All animals are now endangered.
B. Wildlife habitat loss is too serious.
C. The wildlife extinction is speeding up.
D. Backbone animals are decreasing slowly.
解析:主旨大意题。结合文章首段中出现的词“extinction” 以及全文内容可知,本文主要讲述了野生动物濒临灭绝的原因。故选C。
答案:C
D
12. It is also, perhaps, the gentlest(最温顺的), but not always!
Elephants are like humans in some ways. They can live for a long time—fifty or sixty years. They can remember things very well. 13. ____ If a female(雌性的) elephant dies, her daughters and her granddaughters will be sad for many months. They would stay with the dead body for a long time. And they never forget a dead friend.
Elephants are like us, but they are also different from us. They live in the families of females where the females are the kings. 14.______ But the females will soon send them away. An elephant family keeps only daughters, mothers and grandmothers.
The females would stay together for fifty, sixty or a hundred years. The older animals look after the younger ones. 15. 　
But what happens to the male(雄性的) elephants? Well, the young males just will stay with their mothers for a short time. Then they must leave the family, because the females will send them away. A male elephant does not often have a friend. 16. Sometimes if the females invite a male elephant, then he can visit them and stay. But soon his “wife” and sisters will send him away again. The females have a very happy family life. But what do the male elephants think about it? We don’t know.

A. They never forget great sadness or great happiness.

G. The male elephants want to stay with the female ones, but they are not welcome.
12. 解析:根据下文介绍了大象这一动物,且空格后“It is also,perhaps, the gentlest, but not always!”可知,它也许也是最温顺的动物,但并不总是这样!F项“大象是世界上最大的四条腿动物”符合文意,故选F项。
答案:F
13. 解析:根据上文“They can remember things very well.” 可知,它们的记忆力很好。A项“它们永远不会忘记巨大的悲伤或巨大的幸福”,符合文意,故选A项。
答案:A
14. 解析:根据上文“Elephants are like us,but they are also different from us. They live in the families of females where the females are the kings.”可知,大象和我们一样,但它们也不同于我们。它们生活在雌性家族中,雌性是国王。D项“会有一些年幼的雄象——一些‘雄性幼象’”,符合语境,故选D项。
答案:D
15. 解析:根据上文“The females would stay together for fifty,sixty or a hundred years. The older animals look after the younger ones.” 可知,雌性会在一起待上五十、六十或一百年,年长的动物照顾年幼的动物。E项“母亲们教它们的女儿,并树立一个好榜样”,符合文意,故选E项。
答案:E
16. 解析:根据上文“Then they must leave the family,because the females will send them away. A male elephant does not often have a friend.” 可知,然后它们必须离开这个家庭,因为雌象会把它们赶走,雄象通常没有朋友。B项“它住在远离家庭和其他雄性大象的地方”,符合文意,故选B项。
答案:B
