  “THEY’RE ALL IN TROUBLE,” says Kenyan ecologist Paula Kahumbu. “All elephants are in major, major trouble.”
  Populations of the three species have declined: savanna (熱帶草原) elephants, forest elephants, and the smaller-eared Asian elephants. And we’re to blame. We’ve expanded into elephant territory, building homes and roads, cutting down forests and planting crops. Besides, with the rise of poaching (偷獵), the number of elephants has decreased and became dangerously low in the past five decades.
  “Poaching doesn’t just destroy animals,” says Kahumbu, “it gradually weakens society.” That’s why her organization monitored poaching cases in Kenyan courts, launched a campaign called Hands Off Our Elephants and educated children on the value of wildlife. Kahumbu’s goal is noble and urgent: to change “the whole national awareness about conservation”.
  Now, she’s taking her message to an international stage with Secrets of the Elephants, a four-part series on National Geographic. It explores the hidden lives of elephants in four habitats — Asia, plus African forests, deserts, and savannas — as well as the people who are racing to save the animals.
  “We kind of know what they need, but we aren’t always generous enough.” Secrets of the Elephants, she hopes, will familiarize people with the wildlife that lives among them.
  While making the series, the difficult situation of some elephants shocked her. “You look at their faces and they look so sad,” she says. She particularly noticed this in Asia, where Asian elephants and people live in increasingly close distance.
  “Despite decades of research into African elephants, much research into Asian elephants has fallen behind — which is why our programme in the following pages will focus on this species,” she adds.
1.What does Paragraph 2 focus on?
A.The features of three species of elephants. B.The different situations of the elephants.
C.The causes for the decrease of the elephants. D.The impact of human behaviors on elephants.
2.What did Kahumbu do?
A.She monitored poachers hunting elephants.
B.She filmed a feature about elephants.
C.She started a national wildlife protection movement.
D.She changed people’s awareness of wildlife protection.
3.What can be inferred about the Asian elephants?
A.They like to get close to humans.
B.They are almost ignored by experts.
C.They remain mysterious to humans.
D.They are gradually losing their habitats.
4.What can be a suitable title for the text?
A.Take Action: Stop Poaching
B.Film Series: Secrets of the Elephants
C.Paula Kahumbu: A Brave Kenyan Ecologist
D.Endangered: Three Species of Elephants

  Thousands of emperor penguin chicks across four colonies in Antarctica are believed to have died because of record-low sea ice levels that caused a catastrophic breeding (繁殖) failure in late 2022, according to new research.
  Analysis of satellite images showed the break-up of the stable sea ice and the disappearance of the colonies at a time when chicks had not yet grown their waterproof feathers. Scientists have said emperor penguins face an uncertain future under global heating because they are so dependent on sea ice.
  The research said that the breeding failures in the Bellingshausen Sea never happened before, as it was the first time multiple colonies across a large region had all failed in a single season. “It’s a worrying story,” said Dr Peter Fretwell, a researcher with the British Antarctic Survey and the lead author of the research. “The sea ice loss has been far quicker than we imagined.” Many parts of the region had near-total loss of sea ice. Fretwell estimated as many as 7,000 chicks may have perished. “In some cases it’s possible the sea broke up into smaller floes (浮冰) or under the feet of the penguins,” he said. “If immersed, the chicks will drown. If they get back on to the ice floes, they will freeze because of lack of their waterproof feathers.”
  Dr Barbara Wienecke, a senior research scientist at the Australian Antarctic Division, said“They still have their downy plumage (全身茸毛). If the ice breaks out before they can safely enter the water, the plumage becomes so wet that the chicks die of exposure. It’s extraordinarily upsetting to think of this happening.”
  Both Wienecke and Fretwell said predictions of the future for the penguin species may have to be revised, with the risk potentially greater than previously feared. Fretwell said: “It’s only by changing our behaviour and the amounts of fossil fuels we use will we completely change the situation for these emperor penguins, and many other species. How bad it gets is still up to us.”
5.Which can describe the situation of the emperor penguin chicks?
A.Promising.    B.Alarming. C.Hopeless. D.Inspiring.
6.What do we know about the chicks according to the passage?
A.They are dying of food shortages.
B.They are finding new habitats for breeding.
C.They have learned how to swim in the ice water.
D.They don’t have the kind of feathers protecting them.
7.What does the underlined word “perished” in Paragraph 3 mean?
A.Appeared. B.Adapted.
C.Escaped. D.Died.
8.What does Fretwell want to convey in the last paragraph?
A.Fossil fuels are to blame for the destruction.
B.We should change our behaviour to save the penguins.
C.We should not fear the potential risk as it can be removed.
D.More research should be done to ensure the positive changes.

  A lot of glass today made from sand and sodium carbonate (碳酸鈉) can be reused or melted down and recycled into new items, but it doesn’t break down in the environment and will sit in landfills for thousands of years. A team of Chinese scientists aimed to deal with this environmental concern by developing an eco-conscious alternative.
  In a study published recently in the journal Science Advances, a team at the Chinese Academy of Sciences’ Institute of Process Engineering describe how they engineered biodegradable glass made from amino acids(氨基酸). That glass would have a smaller impact on the environment and can break down in a few weeks or in several months.
  In a test, glass beads (玻璃珠) made out of amino acids were placed under the skin of mice, and the breakdown of the bead and the skin healing process were observed for 30 days. A diagram from the study shows how the mice’s bodies broke down the beads. In that month, the glass implant degraded (降解) beneath the skin, the wound site healed, and fur grew back. “Throughout the experimental period, no mice showed any pain-related behavior that may have been caused by the glass implantation, and none of them experienced obvious weight loss,” the researchers wrote in their paper.
  Although amino acids do degrade over time in the environment, this biodegradable glass is not as durable as traditional glass, because amino acids can break down quickly in heat. In order to overcome this barrier, the researchers chemically modified the amino acids using the heating-cooling procedure applied in glass making. This is when materials for the glass are heated to become soft and then rapidly cooled so as to make the glass tougher.
  “It’s important to point out that this biodegradable glass is currently in the lab stage, and far from large-scale commercialization,” emphasized Yan Xuehai, a professor involved in the study, in a press release.
9.What did the researchers study during the experiment?
A.The mice’s skin healing process.
B.The breakdown of the glass beads.
C.The medical value of the new glass.
D.The glass degradation with less injury to the mice.
10.How do the researchers improve the durability of amino acid glass?
A.Adding more amino acids.
B.Heating the glass and rapidly cooling it.
C.Using special chemical substances.
D.Changing the producing process of glass.
11.What does the underlined word “modified” in Paragraph 4 mean?
A.Transformed. B.Melted.
C.Enlarged. D.Produced.
12.Which of the following can be the best title for the text?
A.A New Kind of Perfect Glass
B.Amino Acids Make Glass Tougher
C.Large-scale Commercial Glass Products
D.Environment-Friendly and Biodegradable Glass

  There are a lot of chemicals that can cause indoor air pollution. A recent project conducted has found over 900 different substances in our home are related to it. Many researchers have already examined the causes of indoor air pollution.  13 
  It has been proved that different kinds of chemicals can be released by building materials and new furniture. Everything from painting and decorating products, bathroom cleaners and beauty products can contain these chemicals.  14  For instance, cooking generates a lot of harmful emissions, like frying meat in oil.
  As a research from Denmark has highlighted, cooking, particularly roasting can damage our body. Roast dinners contain many potentially harmful pollutants.  15  When exposed to cooking emissions, people actually had DNA damage. It can be associated with cell repair processes that trigger cancer — causing genetic changes.  16  And what can we do with it?
  As far as cooking emissions are concerned, no one is suggesting switching to takeaways.  17  For example, cooking meat at high temperatures with lots of fat produces more harmful emissions than boiling pasta. Besides, opening windows and using cooker hoods are preferable so that we can enjoy the roasted meat without those undesirable effects.
A.In the long run, these changes lead to cancer.
B.They might also arise from cooking at home.
C.A wide range of sources are under investigation.
D.Therefore, what results from indoor air pollution?
E.However, most of us have ignored their bad effects.
F.So, what are the main contributors to poor air quality?
G.But we can change how we cook to deal with the emissions.

Ⅰ.
語篇解讀:本文是一篇說明文。文章描述了三種大象數量急劇下降的現狀和原因,以及肯尼亞生態學家Paula Kahumbu的組織對保護大象所作的努力。
1.D 段落大意題。根據第二段內容可知,本段主要講述了人類行為對大象產生的影響。
2.C 細節理解題。根據第三段中的That’s why her organization monitored poaching cases in Kenyan courts, launched a campaign called Hands Off Our Elephants and educated children on the value of wildlife.可知,Kahumbu發起了一項全國的野生動物保護運動。
3.D 推理判斷題。根據倒數第二段內容可知,大象正生活在困境當中,生活得很艱難、痛苦,亞洲的大象和人類住的越來越近,說明大象的棲息地正逐漸被人類占領,它們也逐漸失去了自己的棲息地。
4.D 標題歸納題。根據全文內容可知,本文主要描述了三種大象數量急劇下降、瀕臨滅絕的現狀和原因。因此D項適合作文章標題。
語篇解讀:本文是一篇說明文。研究表明,由于地球變暖,南極的帝企鵝繁殖困難,幼鳥也難以存活。
5.B 推理判斷題。根據第一段內容可知,海洋冰層的減少使帝企鵝的繁殖失敗,而且幼企鵝生存的冰塊也在消失,所以它們的現狀令人擔憂。
6.D 細節理解題。根據第二段第一句可知,幼企鵝還未長出可以保護它們的防水羽毛。
7.D 詞義猜測題。根據第三段最后兩句可知,海上的冰塊會分解成小塊浮冰,幼企鵝會落水溺亡,哪怕爬回浮冰,浸濕的茸毛也會讓它們凍死,因此Fretwell估計大量企鵝會死亡,所以畫線單詞意為“死亡”。
8.B 推理判斷題。根據最后一段Fretwell說的話可知,人類的行為和化石燃料的燃燒導致了帝企鵝的死亡,所以它們的未來取決于人類行為。
語篇解讀:本文是一篇說明文。文章主要介紹了中國科學院的專家團隊利用氨基酸研制出一種可降解的環保玻璃。
9.D 細節理解題。根據第三段最后一句可知,研究人員在實驗中研究出玻璃降解對小鼠損傷較小。
10.B 細節理解題。根據倒數第二段中的This is when materials for the glass are heated to become soft and then rapidly cooled so as to make the glass tougher.可知,研究人員加熱玻璃并迅速冷卻來提高氨基酸玻璃的耐久性。
11.A 詞義猜測題。根據畫線詞上下文可知,為了克服這一障礙,研究人員使用玻璃制造中應用的加熱-冷卻程序對氨基酸進行化學轉換。故畫線詞意思是“轉換”。
12.D 標題歸納題。文章主要介紹了中國科學院的專家團隊利用氨基酸研制出一種可降解的環保玻璃。由此可知,D項(環保型、可生物降解玻璃)最適合作文章標題。
Ⅱ.
語篇解讀:本文是一篇說明文。文章主要說明了室內空氣污染的原因以及減少這一污染的建議。
13.F 上文提到許多研究人員已經研究了室內空氣污染的原因,故此處主要引出下文空氣質量差的原因。F項(那么,空氣質量差的主要原因是什么?)符合語境。
14.B 根據空后一句可知,烹飪也會導致室內空氣質量差。B項(也可能是由于在家做飯引起的)符合語境。
15.E 上文提到了燒烤晚餐含有許多潛在的有害污染物,由此可推測本句是在說明人們對這一問題的態度。E項(然而,我們大多數人都忽視了它們的不良影響)符合語境。
16.A 根據空前兩句可知,長期接觸烹飪排放物可能會導致基因變化。A項(從長遠來看,這些變化會導致癌癥)符合語境。
17.G 空后的例子表明,改變烹飪方式可以減少有害排放物的產生。G項(但是我們可以改變烹飪方式來解決排放問題)符合語境。

MACQUARIE ISLAND:from Chaos① to Conservation②
I am standing on Macquarie Island, in the South-west Pacific Ocean, halfway③ between Australia and Antarctica.Strong winds and stormy seas have helped sculpt④ its long, thin shape.The green grass and bare⑤ rock of its landscape contrast⑥ dramatically⑦, [1]giving it a wild and natural beauty.[2]No visitor would think it surprising that the island is a UNESCO World Heritage⑧ Site.[3]Nor would they fail to imagine how its native inhabitants⑨, including royal penguins⑩, king penguins, and elephant seals, existed in perfect harmony with their natural habitat for thousands of years.
  [1]動詞-ing短語作結果狀語。
[2]句中it作形式賓語,that引導的賓語從句作真正的賓語。
[3]本句為nor置于句首引起的部分倒裝句,其中how引導賓語從句。
But the island’s more recent history tells a different story.[4]It’s a tragic story that began in 1810 when humans arrived on the island. In their ships they unknowingly brought rats and mice.These small animals quickly took over the island, [5]eating the birds’ eggs and attacking baby birds.Cats were brought to the island [6]to control the rats and mice.Unfortunately, the cats subsequently developed an appetite for the birds, too.
  [4]句中that引導定語從句,修飾先行詞story;when引導定語從句,修飾1810。
[5]動詞-ing短語作狀語。
[6]動詞不定式短語作目的狀語。
Meanwhile, rabbits were introduced to the island as a source of food for humans.Loose on the island, they did [7]what rabbits do best — they multiplied rapidly and began eating the native vegetation and digging holes, [8]which caused soil erosion .The exploding rabbit population provided plentiful food for the cats, meaning that the number of cats also increased.This in turn led to more cats hunting the birds.The end result was that parakeets , once large in number and native to the island, died out in 1891.
  [7]what引導賓語從句;破折號后面的內容是對what rabbits do best的解釋說明。
[8]which引導非限制性定語從句,修飾整個主句。
Even after Macquarie Island became an official nature reserve in the 1970s, the rabbits remained out of control .[9]Experts felt it necessary to come up with a plan to remove all the rabbits from the island. With this goal in mind, a virus was released onto the island.But although the virus caused the rabbit population to decrease from 130,000 to around 10,000, it also meant less food for the cats.The cats in consequence turned their attention — and their stomachs — back to the native birds, [10]killing up to 60,000 each year.In the 1980s, traps and dogs were used to catch the cats.The last Macquarie Island cat was caught in 2000.
  [9]句中it作形式賓語,動詞不定式短語to come up with a plan作真正的賓語;動詞不定式短語to remove all the rabbits from the island作目的狀語。
[10]動詞-ing短語作結果狀語。
But as the saying goes,“While the cat’s away, the mice will play.” With the departure of the cats from the island, the mouse and rat population started to increase.And remember those 10,000 or so rabbits? [11]It turned out that they developed an immunity to the virus, and their numbers exploded once again. Then, in 2006, the rabbits’ digging caused some land to collapse , and killed a substantial number of penguins.[12]This incident made it clear that the rat, mouse and rabbit problem needed solving once and for all .

麥夸里島:從混亂不堪到精心保護
  我正站在麥夸里島上,這里位于太平洋的西南部,澳大利亞和南極洲的中間。強風和驚濤駭浪將海島塑成現在狹長的形狀。綠草和光禿的巖石形成的景觀反差巨大,使海島呈現出一種狂野和天然的美。這座島是聯合國教科文組織確立的世界遺產,游客們都認為其名副其實。他們也不難想象出,數千年來,包括帝企鵝、王企鵝和象海豹在內的當地動物是如何與其自然棲息地完美地和諧共存的。
但是,這座島近些年的遭遇則是截然不同的故事。悲劇從人類1810年來到這座島嶼開始。他們不經意間隨船帶來了大鼠和小鼠。這些小動物很快就占領了島嶼,它們吃鳥蛋并攻擊幼鳥。為控制鼠患,人們帶來了貓,但不幸的是,貓隨后也開始以鳥為食。
與此同時,人們把兔子引進島上作為食物。由于在島上放任其生存,兔子做了自己最擅長的事——飛快地繁殖,它們開始吃當地植被并挖洞,造成了土壤侵蝕。爆炸式增長的兔子數量給貓提供了充足的食物,這意味著貓的數量也增加了,相應地就有更多貓捕食鳥類。最終結果是,曾經數量眾多的當地物種長尾小鸚鵡在1891年滅絕。
即使在20世紀70年代麥夸里島成為官方自然保護區后,兔子仍然不受控制。專家認為,必須想辦法清除島上所有的兔子。懷著這個目標,人們投放了一種病毒到島上。然而,雖然病毒使得兔子的數量從130,000降到約10,000只,但這也意味著貓的食物變少了。因此,貓把注意力和胃口重新轉向了當地鳥類,每年捕食多達60,000只。20世紀80年代,人們利用捕獵夾和狗來抓貓。2000年,麥夸里島上的最后一只貓被抓。
  但正如俗語所說:“山中無老虎,猴子稱大王。”貓從島上消失了,小鼠和大鼠的數量便開始增加。還記得那10,000只左右的兔子嗎?它們最終對病毒產生了免疫,數量又一次激增。隨后,在2006年,兔子挖的洞造成一些土地坍塌,導致大量企鵝死亡。這一事件清楚地表明,大鼠、小鼠和兔子泛濫的問題需要一次徹底地解決。
所以,正是為了解決這個問題,我來到麥夸里島上參與一項行動。行動的第一步利用了直升機向島上投放毒藥。下一步是清除最后殘存的入侵物種,這就是我的工作了——和我的狗一起。這些狗受訓去尋找剩下的每一只老鼠和兔子,同時又不傷害當地動物。這次干預行動是這場悲劇漫長而屢被貽誤的大結局,但這是我們人類應該做的,我們虧欠這座島嶼一個美好的結局。
附言:2014年,麥夸里島正式宣布已無有害生物,島上的生態環境終于走上了恢復之路。

MACQUARIE ISLAND:from Chaos① to Conservation②
I am standing on Macquarie Island, in the South-west Pacific
Ocean, halfway③ between Australia and Antarctica.Strong winds and
stormy seas have helped sculpt④ its long, thin shape.The green grass and
bare⑤ rock of its landscape contrast⑥ dramatically⑦, [1]giving it a wild
and natural beauty.[2]No visitor would think it surprising that the island
is a UNESCO World Heritage⑧ Site.[3]Nor would they fail to imagine
how its native inhabitants⑨, including royal penguins⑩, king
penguins, and elephant seals, existed in perfect harmony with their
natural habitat for thousands of years.
  [1]動詞-ing短語作結果狀語。
[2]句中it作形式賓語,that引導的賓語從句作真正的賓語。
[3]本句為nor置于句首引起的部分倒裝句,其中how引導賓

⑨inhabitant n.棲居的動物
⑩penguin n.企鵝
in harmony with與……和諧相處,與……協調一致
habitat n.棲息地
But the island’s more recent history tells a different story.[4]It’s a
tragic story that began in 1810 when humans arrived on the island. In
their ships they unknowingly brought rats and mice.These small
animals quickly took over the island, [5]eating the birds’ eggs and
attacking baby birds.Cats were brought to the island [6]to control the rats
and mice.Unfortunately, the cats subsequently developed an appetite
for the birds, too.
  [4]句中that引導定語從句,修飾先行詞story;when引導定語從句,修飾1810。

tragic adj.悲慘的;不幸的
unknowingly adv.不知不覺地,不經意中
rat n.大老鼠
take over 占領;接管;接任
subsequently adv.后來,隨后
appetite n.胃口,食欲
Meanwhile, rabbits were introduced to the island as a source of food
for humans.Loose on the island, they did [7]what rabbits do best —
they multiplied rapidly and began eating the native vegetation and
digging holes, [8]which caused soil erosion .The exploding rabbit
population provided plentiful food for the cats, meaning that the
number of cats also increased.This in turn led to more cats hunting
the birds.The end result was that parakeets , once large in number and
native to the island, died out in 1891.
  [7]what引導賓語從句;破折號后面的內容是對what rabbits do
best的解釋說明。
[8]which引導非限制性定語從句,修飾整個主句。

parakeet n.長尾(小)鸚鵡
die out 滅絕,逐漸消失
Even after Macquarie Island became an official nature reserve in the
1970s, the rabbits remained out of control .[9]Experts felt it necessary
to come up with a plan to remove all the rabbits from the island. With
this goal in mind, a virus was released onto the island.But although
the virus caused the rabbit population to decrease from 130,000 to
around 10,000, it also meant less food for the cats.The cats in
consequence turned their attention — and their stomachs — back to the
native birds, [10]killing up to 60,000 each year.In the 1980s, traps
and dogs were used to catch the cats.The last Macquarie Island cat was
caught in 2000.
  [9]句中it作形式賓語,動詞不定式短語to come up with a plan作
真正的賓語;動詞不定式短語to remove all the rabbits from the island

come up with 想出,提出(計劃、想法等)
virus n.病毒
release v.釋放;排放
decrease v.(使)變小,(使)減少
in consequence 結果,因此
trap n.夾子,陷阱
But as the saying goes,“While the cat’s away, the mice will
play.” With the departure of the cats from the island, the mouse and
rat population started to increase.And remember those 10,000 or so
rabbits? [11]It turned out that they developed an immunity to the
virus, and their numbers exploded once again. Then, in 2006, the
rabbits’ digging caused some land to collapse , and killed a substantial
number of penguins.[12]This incident made it clear that the rat,
mouse and rabbit problem needed solving once and for all .
  [11]句中It作形式主語,that引導的主語從句作真正的主語。
[12]句中it作形式賓語,that引導的賓語從句作真正的賓語。
departure n.離開
turn out原來是;結果是
immunity n.免疫力
explode v.突然增加
collapse v.倒坍;塌下
substantial adj.大量的,多的
incident n.事件
once and for all 徹底地;一勞永逸地
So, I am here on Macquarie Island to participate in the programme
to tackle this very problem.The first step involved poison being dropped
from helicopters.[13]The next step is to remove the last remaining
invading species, and that’s where I come in — with my dogs. They
have been trained to find every last one, without harming the native
animals.This intervention is a long, much-delayed ending to a sad
story, but we humans owe it to the island to give it a happy ending.
  Postscript :In 2014, Macquarie Island was declared pest -free
and the island’s ecology is finally on the road to recovery.
[13]句中動詞不定式短語to remove ...作表語;where引導表語

【參考譯文】
麥夸里島:從混亂不堪到精心保護
  我正站在麥夸里島上,這里位于太平洋的西南部,澳大利亞和南
極洲的中間。強風和驚濤駭浪將海島塑成現在狹長的形狀。綠草和光
禿的巖石形成的景觀反差巨大,使海島呈現出一種狂野和天然的美。
這座島是聯合國教科文組織確立的世界遺產,游客們都認為其名副其
實。他們也不難想象出,數千年來,包括帝企鵝、王企鵝和象海豹在
內的當地動物是如何與其自然棲息地完美地和諧共存的。
但是,這座島近些年的遭遇則是截然不同的故事。悲劇從人類
1810年來到這座島嶼開始。他們不經意間隨船帶來了大鼠和小鼠。這
些小動物很快就占領了島嶼,它們吃鳥蛋并攻擊幼鳥。為控制鼠患,
人們帶來了貓,但不幸的是,貓隨后也開始以鳥為食。
與此同時,人們把兔子引進島上作為食物。由于在島上放任其生
存,兔子做了自己最擅長的事——飛快地繁殖,它們開始吃當地植被
并挖洞,造成了土壤侵蝕。爆炸式增長的兔子數量給貓提供了充足的
食物,這意味著貓的數量也增加了,相應地就有更多貓捕食鳥類。最
終結果是,曾經數量眾多的當地物種長尾小鸚鵡在1891年滅絕。
即使在20世紀70年代麥夸里島成為官方自然保護區后,兔子仍然
不受控制。專家認為,必須想辦法清除島上所有的兔子。懷著這個目
標,人們投放了一種病毒到島上。然而,雖然病毒使得兔子的數量從
130,000降到約10,000只,但這也意味著貓的食物變少了。因此,
貓把注意力和胃口重新轉向了當地鳥類,每年捕食多達60,000只。
20世紀80年代,人們利用捕獵夾和狗來抓貓。2000年,麥夸里島上的
最后一只貓被抓。
  但正如俗語所說:“山中無老虎,猴子稱大王。”貓從島上消失
了,小鼠和大鼠的數量便開始增加。還記得那10,000只左右的兔子
嗎?它們最終對病毒產生了免疫,數量又一次激增。隨后,在2006
年,兔子挖的洞造成一些土地坍塌,導致大量企鵝死亡。這一事件清
楚地表明,大鼠、小鼠和兔子泛濫的問題需要一次徹底地解決。
所以,正是為了解決這個問題,我來到麥夸里島上參與一項行
動。行動的第一步利用了直升機向島上投放毒藥。下一步是清除最后
殘存的入侵物種,這就是我的工作了——和我的狗一起。這些狗受訓
去尋找剩下的每一只老鼠和兔子,同時又不傷害當地動物。這次干預
行動是這場悲劇漫長而屢被貽誤的大結局,但這是我們人類應該做
的,我們虧欠這座島嶼一個美好的結局。
附言:2014年,麥夸里島正式宣布已無有害生物,島上的生態環
境終于走上了恢復之路。

  “THEY’RE ALL IN TROUBLE,” says Kenyan ecologist Paula
Kahumbu. “All elephants are in major, major trouble.”
  Populations of the three species have declined: savanna (熱帶草
原) elephants, forest elephants, and the smaller-eared Asian
elephants. And we’re to blame. We’ve expanded into elephant
territory, building homes and roads, cutting down forests and planting
crops. Besides, with the rise of poaching (偷獵), the number of
elephants has decreased and became dangerously low in the past five
decades.
  “Poaching doesn’t just destroy animals,” says Kahumbu, “it
gradually weakens society.” That’s why her organization monitored
poaching cases in Kenyan courts, launched a campaign called Hands Off
Our Elephants and educated children on the value of wildlife.
Kahumbu’s goal is noble and urgent: to change “the whole national
awareness about conservation”.
  Now, she’s taking her message to an international stage with
Secrets of the Elephants, a four-part series on National Geographic. It
explores the hidden lives of elephants in four habitats — Asia, plus
African forests, deserts, and savannas — as well as the people who are
racing to save the animals.
  “We kind of know what they need, but we aren’t always generous
enough.” Secrets of the Elephants, she hopes, will familiarize people
with the wildlife that lives among them.
  While making the series, the difficult situation of some elephants
shocked her. “You look at their faces and they look so sad,” she says.
She particularly noticed this in Asia, where Asian elephants and people
live in increasingly close distance.
  “Despite decades of research into African elephants, much
research into Asian elephants has fallen behind — which is why our
programme in the following pages will focus on this species,” she adds.

  Thousands of emperor penguin chicks across four colonies in
Antarctica are believed to have died because of record-low sea ice levels
that caused a catastrophic breeding (繁殖) failure in late 2022,
according to new research.
  Analysis of satellite images showed the break-up of the stable sea ice
and the disappearance of the colonies at a time when chicks had not yet
grown their waterproof feathers. Scientists have said emperor penguins
face an uncertain future under global heating because they are so
dependent on sea ice.
  The research said that the breeding failures in the Bellingshausen Sea
never happened before, as it was the first time multiple colonies across a
large region had all failed in a single season. “It’s a worrying story,”
said Dr Peter Fretwell, a researcher with the British Antarctic Survey and
the lead author of the research. “The sea ice loss has been far quicker
than we imagined.” Many parts of the region had near-total loss of sea
ice. Fretwell estimated as many as 7,000 chicks may have perished.
“In some cases it’s possible the sea broke up into smaller floes (浮
冰) or under the feet of the penguins,” he said.
“If immersed, the chicks will drown. If they get back on to the ice floes,
they will freeze because of lack of their waterproof feathers.”
  Dr Barbara Wienecke, a senior research scientist at the Australian
Antarctic Division, said“They still have their downy plumage (全身茸毛). If the ice breaks out before they can safely enter the water, the
plumage becomes so wet that the chicks die of exposure. It’s
extraordinarily upsetting to think of this happening.”
  Both Wienecke and Fretwell said predictions of the future for the
penguin species may have to be revised, with the risk potentially greater
than previously feared. Fretwell said: “It’s only by changing our
behaviour and the amounts of fossil fuels we use will we completely
change the situation for these emperor penguins, and many other
species. How bad it gets is still up to us.”

5. Which can describe the situation of the emperor penguin chicks?
A. Promising. B. Alarming.
C. Hopeless. D. Inspiring.
解析: 推理判斷題。根據第一段內容可知,海洋冰層的減少使
帝企鵝的繁殖失敗,而且幼企鵝生存的冰塊也在消失,所以它們的
現狀令人擔憂。
6. What do we know about the chicks according to the passage?
A. They are dying of food shortages.
B. They are finding new habitats for breeding.
C. They have learned how to swim in the ice water.
D. They don’t have the kind of feathers protecting them.
解析: 細節理解題。根據第二段第一句可知,幼企鵝還未長出
可以保護它們的防水羽毛。
7. What does the underlined word “perished” in Paragraph 3 mean?
A. Appeared. B. Adapted.
C. Escaped. D. Died.
解析: 詞義猜測題。根據第三段最后兩句可知,海上的冰塊會
分解成小塊浮冰,幼企鵝會落水溺亡,哪怕爬回浮冰,浸濕的茸毛
也會讓它們凍死,因此Fretwell估計大量企鵝會死亡,所以畫線單
詞意為“死亡”。
8. What does Fretwell want to convey in the last paragraph?
A. Fossil fuels are to blame for the destruction.
B. We should change our behaviour to save the penguins.
C. We should not fear the potential risk as it can be removed.
D. More research should be done to ensure the positive changes.
解析: 推理判斷題。根據最后一段Fretwell說的話可知,人類的
行為和化石燃料的燃燒導致了帝企鵝的死亡,所以它們的未來取決
于人類行為。

  A lot of glass today made from sand and sodium carbonate (碳酸
鈉) can be reused or melted down and recycled into new items, but it
doesn’t break down in the environment and will sit in landfills for
thousands of years. A team of Chinese scientists aimed to deal with this
environmental concern by developing an eco-conscious alternative.
  In a study published recently in the journal Science Advances, a
team at the Chinese Academy of Sciences’ Institute of Process
Engineering describe how they engineered biodegradable glass made from
amino acids(氨基酸). That glass would have a smaller impact on the
environment and can break down in a few weeks or in several months.
  In a test, glass beads (玻璃珠) made out of amino acids were
placed under the skin of mice, and the breakdown of the bead and the
skin healing process were observed for 30 days. A diagram from the study
shows how the mice’s bodies broke down the beads. In that month, the
glass implant degraded (降解) beneath the skin, the wound site
healed, and fur grew back. “Throughout the experimental period, no
mice showed any pain-related behavior that may have been caused by the
glass implantation, and none of them experienced obvious weight
loss,” the researchers wrote in their paper.
  Although amino acids do degrade over time in the environment, this
biodegradable glass is not as durable as traditional glass, because amino
acids can break down quickly in heat. In order to overcome this barrier,
the researchers chemically modified the amino acids using the heating-
cooling procedure applied in glass making. This is when materials for the
glass are heated to become soft and then rapidly cooled so as to make the
glass tougher.
  “It’s important to point out that this biodegradable glass is
currently in the lab stage, and far from large-scale
commercialization,” emphasized Yan Xuehai, a professor involved in the study, in a press release.

9. What did the researchers study during the experiment?
A. The mice’s skin healing process.
B. The breakdown of the glass beads.
C. The medical value of the new glass.
D. The glass degradation with less injury to the mice.

10. How do the researchers improve the durability of amino acid glass?
A. Adding more amino acids.
B. Heating the glass and rapidly cooling it.
C. Using special chemical substances.
D. Changing the producing process of glass.
解析: 細節理解題。根據倒數第二段中的This is when
materials for the glass are heated to become soft and then rapidly
cooled so as to make the glass tougher.可知,研究人員加熱玻璃并
迅速冷卻來提高氨基酸玻璃的耐久性。
11. What does the underlined word “modified” in Paragraph 4 mean?
A. Transformed. B. Melted.
C. Enlarged. D. Produced.
解析: 詞義猜測題。根據畫線詞上下文可知,為了克服這一
障礙,研究人員使用玻璃制造中應用的加熱-冷卻程序對氨基酸進
行化學轉換。故畫線詞意思是“轉換”。
12. Which of the following can be the best title for the text?
A. A New Kind of Perfect Glass
B. Amino Acids Make Glass Tougher
C. Large-scale Commercial Glass Products
D. Environment-Friendly and Biodegradable Glass
解析: 標題歸納題。文章主要介紹了中國科學院的專家團隊

  There are a lot of chemicals that can cause indoor air pollution. A
recent project conducted has found over 900 different substances in our
home are related to it. Many researchers have already examined the causes
of indoor air pollution.  13 
  It has been proved that different kinds of chemicals can be released by
building materials and new furniture. Everything from painting and
decorating products, bathroom cleaners and beauty products can contain
these chemicals.  14  For instance, cooking generates a lot of harmful
emissions, like frying meat in oil.
  As a research from Denmark has highlighted, cooking, particularly roasting can damage our body. Roast dinners contain many potentially harmful pollutants.  15  When exposed to cooking emissions, people actually had DNA damage. It can be associated with cell repair processes that trigger cancer — causing genetic changes.  16  And what can we do with it?
  As far as cooking emissions are concerned, no one is suggesting
switching to takeaways.  17  For example, cooking meat at high
temperatures with lots of fat produces more harmful emissions than boiling
pasta. Besides, opening windows and using cooker hoods are preferable
so that we can enjoy the roasted meat without those undesirable effects.
A. In the long run, these changes lead to cancer.
B. They might also arise from cooking at home.
C. A wide range of sources are under investigation.
D. Therefore, what results from indoor air pollution?
E. However, most of us have ignored their bad effects.
F. So, what are the main contributors to poor air quality?
G. But we can change how we cook to deal with the emissions.

15. E 上文提到了燒烤晚餐含有許多潛在的有害污染物,由此可推
測本句是在說明人們對這一問題的態度。E項(然而,我們大多數人
都忽視了它們的不良影響)符合語境。
16. A 根據空前兩句可知,長期接觸烹飪排放物可能會導致基因變

17. G 空后的例子表明,改變烹飪方式可以減少有害排放物的產
生。G項(但是我們可以改變烹飪方式來解決排放問題)符合語境。
