2.Over the past 50 years, about 17 per cent of the rainforest has disappeared due to human activities such as agriculture and cattle farming.
赏析:本句使用了“百分数+of+名词”作主语,明确指出了人类活动对雨林造成的严重破坏,同时使用such as具体列举了危及雨林的人类活动。注意:“分数或百分数+of+名词”构成的短语作主语时,其谓语动词的数要根据短语后面名词的数而定。
3.As the impact of human activities continues to grow and the list of species in danger of extinction becomes longer, we are left with a question: can we afford to damage the “lungs of the planet”?
赏析:本句是文章的尾句。as引导的时间状语从句与比较级的搭配使用强调了这些人类活动正在持续不断地带来更严重的后果。后半句使用了反问句来结束文章,直击读者内心,引发读者对这一问题的反思,突出了本文的主旨。

藏羚羊是我国一级保护动物。由于盗猎猖獗,藏羚羊在上个世纪末曾一度处于濒临灭绝的边缘,但在政府和民间组织的多方努力下,藏羚羊保护工作取得了显著成效,藏羚羊数量逐年上升,2015年从濒危物种降级为易危物种。了解藏羚羊的现状及其曾经面临的危机有助于我们树立保护动物的意识,感悟人与自然和谐相处的重要性和重大意义。
My guide is Zhaxi, a villager from Changtang.He works at the Changtang National Nature Reserve.The reserve is a shelter for the animals and plants of northwestern Xizang.To Zhaxi, the land is sacred and protecting the wildlife is a way of life.“We're not trying to save the animals,” he says.“Actually, we're trying to save ourselves.”
The 1980s and 1990s were bad times for the Tibetan antelope.The population dropped by more than 50 percent.Hunters were shooting antelopes to make profits.Their habitats were becoming smaller as new roads and railways were built.
In order to save this species from extinction, the Chinese government placed it under national protection.Zhaxi and other volunteers watched over the antelopes day and night to keep them safe from attacks.Bridges and gates were added to let the antelopes move easily and keep them safe from cars and trains.
The measures were effective.The antelope population has recovered and in June 2015, the Tibetan antelope was removed from the endangered species list.The government, however, does not intend to stop the protection programmes, since the threats to the Tibetan antelope have not yet disappeared.

Ⅰ.阅读理解
A
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 (固定) 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.

Every day for a week, a strange, happy visitor would drop to play with Vanessa Prior's pet dog Bobby.Prior thought Bobby had made a new dog friend.It seemed very friendly and got well along with Bobby.They would run after each other, play on the pool cover, gently wrestle or nap side by side.
At first she thought it was a wild dog.But when she posted a photo of the two playing on the social media, a pet rescue center called her.The group told her the Atlanta Wolf Project had been trying to catch the wolf for months, but they failed.Prior gave them new hope.
Because of the wolf's friendship with her pet dog, it was likely to come back to her backyard.Researchers hoped Prior could help them.When they put some traps in the back of her yard, Prior got a very complicated feeling.She couldn't describe what it was, but she was closely surrounded by it.The wolf would be in a safe place, but she would do something that harmed Bobby's feelings.
Researchers told Prior that they would take the rare, black wolf to the Yellow River Wildlife Sanctuary where it would live with another wolf.They didn't think it a fulfilling situation for a wild animal like a wolf to have a connection with humans' life.They need to keep a natural awareness to humans and pets and keep to themselves.
Wolf experts added they would look into the genetics of the animal to try to learn why it liked to get close to people and tried to play with their pets.Some experts believe it could have a history with well-meaning humans.Prior had not expected that she and Bobby should meet such a special and lovely wolf.They just hoped the dear friend all the best.

Ninety-seven percent of Earth's water is ocean.No blue, no green.If you think the ocean isn't important, imagine Earth without it.Fifty years ago, when I began exploring the ocean, no one realized that we human being could do anything to harm the ocean.
For me, as a woman scientist, it all began in 1953 when I first tried diving.In 1979, by using a submersible (潜水器), I had a chance to reach the ocean floor which was six miles offshore and 1,250 feet down.Since then, I've used about 30 kinds of submarines.We need new deep-diving submersible.We need to see the undersea mountains and understand life in the deep sea.Exploring and protecting the wild ocean is my big wish.
What's worrying us is that an ice-free Arctic Ocean may happen in this century.That's bad news for the polar bears.Additional CO2 is not only driving global warming, but also changing ocean chemistry, making the sea more acidic (酸的).That's bad news for coral reefs and oxygen-producing plankton (浮游生物).Actually, nearly half of the coral reefs have disappeared.We're putting hundreds of millions of tons of plastic and other rubbish into the sea.We're blocking the ocean,
poisoning the planet's circulatory system.Most of the turtles, sharks, tunas and whales are way down in numbers.All of these are part of our life support system.
Health to the ocean means health for us.I wish we would use all means — films, explorations, the web, new submarines — and campaign to stimulate public support for ocean protected areas.My wish is a big wish, but if we can make it happen, it can truly save and restore the ocean, the blue heart of the planet.For the children of today, for tomorrow's children: as never again, now is the time.
语篇解读:本文是一篇说明文。文章强调了海洋的重要性,指出如今海洋正在遭受人类的破坏,作者认为海洋的健康意味着我们的健康,我们应该共同努力保护海洋。
9.Why does the writer say “No blue, no green.” in the first paragraph?
A.To tell us the colours of the earth.
B.To refer to the ocean and the land.
C.To show the importance of ocean.
D.To encourage us to explore the ocean.
√
解析:推理判断题。根据第一段中的“Ninety-seven percent of Earth's water is ocean.No blue, no green.If you think the ocean isn't important, imagine Earth without it.”可推知,作者在第一段说“No blue, no green.”是为了显示海洋的重要性。
10.What should we do to protect the ocean according to the text?
A.Make joint efforts.
B.Save life support system.
C.Encourage children to take action.
D.Explore the ocean by new technology.
√
解析:推理判断题。根据最后一段中的“I wish we would use all means — films, explorations, the web, new submarines — and campaign to stimulate public support for ocean protected areas.”可知,我们应该通过共同努力来保护海洋。
11.What does the underlined word “it” in the last paragraph refer to?
A.Means. B.Campaign.
C.Public support. D.Wish.
√
解析:代词指代题。根据最后一段中的“I wish we would use all means ...to stimulate public support for ocean protected areas.”以及画线词所在句可知,作者认为自己的愿望是一个很大的愿望,但如果我们能实现它,这个愿望就能真正拯救和恢复海洋。故it指的是“愿望”。
12.What's the writer's attitude towards the current situation of the ocean?
A.Negative. B.Concerned.
C.Uncertain. D.Indifferent.
√
解析:观点态度题。根据最后一段中的“Health to the ocean means health for us.”以及“For the children of today, for tomorrow's children: as never again, now is the time.”并结合作者在文中强调了海洋的重要性,认为海洋的健康意味着我们的健康,我们应该共同努力保护海洋可推知,作者对海洋的现状持担忧态度。
Ⅱ.阅读七选五
How to Protect Wildlife
Wildlife faces threats from habitat destruction, pollution, and other human actions.Although protecting wildlife may seem too hard at times, even small actions can help protect many different animals. 13
•Create wildlife-friendly areas.When trying to make your garden more beautiful, choose plants that can provide food and shelter for native wildlife.This will also help cut down on pollution. 14
• 15 By using less water and fewer fuels, you will be helping to protect the wildlife around you.Take buses or the subway when you can and turn off electric devices when you're not using them.
•Buy products that are wildlife-friendly. 16 Keep in mind that some endangered animals are killed by traps, catches or hunters who are after other wildlife within the same habitat.
•Limit family size.Population growth is one of the major factors in habitat destruction.With the rapidly growing population, more and more habitats for wildlife are occupied by humans. 17 In this way, the Earth's population will stabilize and native habitats can be protected.
A.Live a greener life.
B.Donate money to organizations.
C.Each family should be limited to one or two children.
D.Avoid products that are made from endangered animals.
E.Protecting wildlife from being endangered is every family's duty.
F.Here are some tips on how to protect wildlife through small actions.
G.Build bird houses to your garden or yard to attract and shelter these species.
语篇解读:本文是一篇说明文。文章就如何保护野生动植物提出了切实可行的建议,并希望读者也贡献自己的一份力量。
13.选F 上文提到小的举动就能帮助保护许多不同的动物,下文则介绍了一些具体的方法。故F项“这里是一些关于如何通过小的举动保护野生动植物的方法”承上启下,符合语境。
14.选G 该段讲的是创造适合野生动植物生存的环境。故G项“在花园或庭院安设鸟窝来吸引、保护这些物种”承接上文,符合语境。
15.选A 下文提到要保护水资源、乘坐公共交通、节约水电等一些绿色生活方式。故A项“过更绿色的生活”作为主题句最能概括本段主旨。
16.选D 空处承接段首主题句“购买野生动植物友好型产品”,即我们要拒绝购买由野生动植物制成的物品。故D项“避免购买由濒危动植物制成的产品”符合语境。
17.选C 本段主题是限制家庭成员规模,人口过多会占据野生动植物的栖息地,空处下一句也指出了这种方法的好处。故C项“每个家庭限制生一到两个孩子”承上启下,符合语境。
A Day in the Clouds
The air is thin and we have to rest several times on the short hike from camp.To our left, snow-covered mountains disappear into clouds that seem almost close enough to touch.On the plain in front of us, we can just make out a herd of graceful animals.Tibetan antelopes.
Tibetan antelopes live on the plains of Xizang, Xinjiang, and Qinghai.Watching them move slowly across the green grass, I'm struck by their beauty.I'm also reminded of the danger .They were hunted, illegally, for their valuable fur.
In the evening, I drink a cup of tea and watch the stars.I think about the antelopes and what Zhaxi told me.Much is being done to protect wildlife, but if we really want to save the planet, we must change our way of life.a threat to wildlife and to our planet.
