The science of the Antarctic: An exploration by air and sea
7 days
Join New Scientist for an interesting trip exploring the world's largest ocean preserve (保护区) and most original sea ecosystem (生态系统)．
Day 1: Arrive into Punta Arenas (Chile)
Arrive into Punta Arenas， where you will be met and transported to the group hotel． Punta Arenas lies at the foot of the Andes with noticeable views across the Straits of Magellan to Tierra Del Fuego． It is Patagonia's liveliest and most interesting city． Everything in the town is within walking distance．
Days 23: Observe Elephant Island
While sailing around the White Continent， huge icebergs announce your arrival in Antarctic waters． Observe Elephant Island， where the shipwrecked (遭遇海难的) worker of Shackleton found shelter while he and five finest men carried on towards South Georgia in a tiny lifeboat． The guides will explain the story． Stormy conditions hardly allow for ashore landing， but you will still see the historic island from the ship．
Days 46: Explore South Georgia
Tour the protected waters of South Georgia． The wildlife on South Georgia is rich， especially the birdlife． Visits to a rookery containing 150，000 king penguins or the nesting home of thousands of black browed albatrosses are remarkable wildlife experiences． If the weather is favourable， visits to Fortuna Bay， Salisbury Plains， Prion Island， and Elsehul Bay are also planned．
Day 7: Depart Santiago
After breakfast， the tour has finished and you can fly home or spend a few days in the fascinating capital city of Santiago． Talk to our specialists about extending your holiday—we are experts in creating tailor made holidays in this area．

On Scotland's west coast is the Firth of Clyde， a large home to thousands of porpoises (鼠海豚) and one dolphin named Kylie． Kylie hasn't been observed with other common dolphins in at least 14 years—but she's far from alone． On clear days in the Clyde， visitors to the marina can sometimes see Kylie swimming with porpoises， which are about two thirds her size．
New research suggests Kylie's ties to porpoises are closer than scientists imagined． While a common dolphin's vocal (发声的) ability should include a diverse range of clicks， whistles， and etc．， Kylie doesn't whistle． Instead， she “talks” more like porpoises， which communicate using high bursts of clicks．
“The study suggests that she may be communicating with the porpoises， or at least attempting to． It's part of a growing body of work that shows a rich world of interactions between different species of dolphins． Clearly， species in the wild interact much more than we thought，” says dolphin behavior expert Denise Herzing．
To learn more about Kylie's relationship with the porpoises， scientists borrowed a device (装置) to record sounds of Kylie and porpoises when they met each other from 2016 to 2018． “She's definitely identified as a porpoise，” says Nairn， who trained as a sea biologist in college． Researchers also studied thousands of dolphins clicks from the recordings carefully．
While dolphins whistle very often， porpoises never do． Instead， they communicate with what are called narrow band， high frequency (NBHF) clicks． To hear an NBHF click you have to play it about one hundred times slower．
Ever since February， Kylie has been missing． Nairn says he can't help but worry． Nairn and his colleagues say they're eager to look for and listen to Kylie as soon as the spring field season begins—and see what else she might teach us．
24．How does Kylie communicate with the porpoises
A．By whispering． B．By touching．
C．By giving out clicks． D．By nodding her head．
25．What was the device used for
A．Taking clear pictures of Kylie underwater．
B．Learning more about Kylie's habitat．
C．Examining how sea creatures interact each other．
D．Studying the clicks made by Kylie and the porpoises．
26．In what way are porpoises different from dolphins
A．Porpoises never whistle．
B．Porpoises are bigger in size．
C．Porpoises live in fresh waters．
D．Porpoises like living in groups．
27．What is a good way to hear an NBHF click
A．Playing it repeatedly． B．Playing it underwater．
C．Playing it in a quiet place． D．Playing it a lot more slowly．
C
If someone asked you to name a species in need of conservation， it wouldn't take long for you to land upon the polar bear． As the most symbolic animal of the Arctic， polar bears perfectly adapt to such a tough environment． Although most are born on land， polar bears spend the majority of their lives around water and on the sea ice of the Arctic Ocean． While they are not facing upcoming extinction， the destruction (破坏) caused to their habitats by climate change puts their long term survival at risk and their numbers are predicted to decline by 30% by 2050．
It is estimated that there are 26，000 polar bears in the wild， living across countries that border the Arctic Ocean． They are excellent swimmers， able to reach a top speed of 6 mph． They have been known to travel areas of up to 600，000 sq km to find their prey (猎物)． Polar bears have an incredibly well developed sense of smell and can discover prey up to 1 km away．
The Arctic is warming twice as fast as the global average melting the sea ice that is vital to the polar bears' ability to find food． The polar bear's food supply is directly impacted by the melting ice． Seals， their main meal， also breed on the ice． So the whole seal population dwindles too as a consequence of that change． And it has forced polar bears to look further for seals． This has increased conflict between humans and polar bears， as they come closer to human settlements looking for food．
The fight to save polar bears is in fact linked to the joint efforts of us humans． There are several organisations aimed to aid polar bears． Polar Bears International is the only conservation group aimed to help polar bears． Consisting of scientists and conservationists， they are expanding our knowledge about polar bear using the most advanced technology． Another is the International Association for Bear Research and Management (IBA)， a group with over 500 members from over 60 countries who work together to share research and information on eight bear species including the polar bear．
28．What puts the polar bear at risk
A．Illegal hunting． B．Severe pollution．
C．Climate change． D．Invasive species．
29．What can we learn about the polar bear from the Paragraph 2
A．They have a sharp sense of smell．
B．They search for food in a small area．
C．They are poor at swimming．
D．They live in harmony with humans．
30．Which is closest in meaning to “dwindles” underlined in Paragraph 3
A．Expands． B．Decreases．
C．Recovers． D．Disappears．
31．What is the author's purpose in writing the text
A．To introduce polar bears' habitats and hunting skills．
B．To show the influence of climate change．
C．To display some conservation groups' achievements．
D．To call on people to protect polar bears．
D
The ocean， with its vast mysteries hidden in its depths， has long excited human curiosity． From ancient maps decorated with dragons and sea monsters to modern day technology， we've made limited progress in uncovering the secrets of the deep blue． Despite the technological advancements to date， only around five percent of the world's oceans have been mapped．
The power of underwater exploration is currently the biggest obstacle we face． While technologies like wave and tidal power show promise， they are often location dependent． Solar power， on the other hand， offers an ever present and powerful energy source， even beneath the ocean's surface． Sunlight can penetrate (穿透) waters up to 50 meters deep， providing sufficient energy to operate basic appliances． And in recent research conducted by a team from NYU Tandon School of Engineering， solar cells successfully powered AUVs (autonomous underwater vehicles) and communications equipment， demonstrating its enormous potential for undersea exploration．
However， some challenges remain． One lies in the design of existing silicon (硅) solar technology， which is ill suited for underwater environments． Beyond moisture and salt content harmful to electronics in general， silicon solar cells are optimized (使优化) to absorb red and infrared light， which do not penetrate water effectively．
Another critical issue underwater solar cells face is biofouling—the gradual gathering of organic substances on the cells． This buildup blocks light． Furthermore， it affects the underwater vehicles themselves， increasing their weight． Previous experiments revealed that biofouling covered over 50 percent of the surface after just 30 days underwater， significantly hampering solar cell operation．
In the research， the team also tackled practical challenges in designing and testing underwater solar cells． They created innovative solutions， such as using LED lights to copy the light spectrum (光谱) at various depths， removing the need for water during testing．
These experiments demonstrated that silicon based solar cells performed better in shallow depths， while other cell types proved more efficient below two meters． Although these specially designed underwater solar cells are still in their early stages of development， these contributions could lay the foundations for groundbreaking technologies that reveal both the potential of solar energy and the mysterious depths of our unexplored oceans．
32．What does the author intend to tell us in Paragraph 1
A．The ocean is mostly unexplored．
B．The sea has shaped human civilization．
C．Marine exploration technology is urgently needed．
D．Technology promotes humans' underwater exploration．
33．What is the advantage of solar power according to Paragraph 2
A．It is affordable．
B．It is eco friendly．
C．It is location independent．
D．It is efficient in generating electricity．
34．What is the author's attitude towards the underwater solar cells designed by the researchers
A．Unconcerned． B．Favorable．
C．Doubtful． D．Disapproving．
35．In which section of a magazine may this text appear
A．Health． B．Education．
C．Society． D．Nature．

In 1999， journalist Nicholas D．Kristof reported a surprising encounter on a tiny African island． Here， Kristof met a number of elderly men who told him that they were descendants of Chinese sailors many centuries ago． Their ancestors had traded with local Africans， who had given them giraffes to take back to China． __36__
Six centuries ago， a large number of Chinese ships crossed the sea， then travelled west to East Africa． __37__ These seven great expeditions brought a vast web of trading links under Chinese government control．
__38__ Most of the trading involved spices (香料)， wood， and medicines． Zheng He brought them back to the capital． Although these goods were mainly presented to the emperor for his consumption and disposal， foreign ambassadors who came to China were permitted to trade with locals in the capital for handsome profits， which also allowed ordinary Chinese to benefit from international trade．
__39__ In the regions they visited， Zheng He and his fleet (船队) remained a long lasting theme in popular Southeast Asia folk tales． Two surviving records of the expeditions provide detailed accounts of unique Chinese navigation technologies of the time， leaving Chinese rich maritime legacy (遗产) to later generations．
However， the Chinese expedition never sought to establish colonial rule over these oceans by military force． __40__ China's maritime dominance disappeared suddenly in the 1430s because of domestic changes， and the overseas expeditions were eventually ended by the court． All this happened only decades prior to the occurrence of the great age of European discovery and exploration．
A．Seven times， the treasure fleets set off for the unknown．
B．Zheng He's great voyage started at the port of Nanjing．
C．Aside from the economic impact， there was more cultural print．
D．The actual economic impact of the expedition was difficult to evaluate．
E．Zheng He traded China's products for foreign luxuries and daily products．
F．It was intended to facilitate international and trade relationships with others．
G．If it's true， this remote village is evidence of an astonishing episode of maritime exploration in China．

第二节(满分25分)
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
A couple of years ago， I had the pleasure of teaching a young couple to dive (潜水) in Thailand on one of my favorite reefs (礁)． The weather conditions were perfect， with mild currents and excellent sight of the beautiful ocean and the bright， vivid corals． Even with their masks on， I could see the smiles on my students' faces．
The dive couldn't have gone better． However， things changed as we made our way back to the boat． As we swam back along the reef， I noticed the current (水流) changing． As it did， huge quantities of trash and plastic began to flood the area． I saw small reef fish swimming amongst the straws， plastic bags and other bits of rubbish． I noticed that some of the fish were pecking away (啄) at the plastic． By the time we got back on board the boat， there were bits of plastic floating all around us． It looked more like a trash site than the ocean．
When I got home， the first thing I did was to go online and research plastic pollution in the ocean． I was surprised to find out that over the past decade， divers and beach lovers have seen a lot of changes in the oceans． Even very remote locations were suddenly filled with plastic and other chemicals． Plastics were entering our oceans at an alarming rate—up to 12 million tons each year． This huge amount of plastic was wreaking havoc (破坏) not only on the environment， but also on the marine animals that lived in the ocean， such as sea turtles and sea birds． Some of them were sadly mistaking the pieces of plastic for food． Pollution has brought our oceans to the point of disaster， and unless we make a great change， then our oceans and all of its living things， will be at risk．
Since that unforgettable plastic polluted dive， I have become an ocean supporter and spend my days trying to get the message out there about just how harmful ocean pollution is， not only to marine life， but also to mankind．
注意：
1．续写词数应为150个左右；
2．请按如下格式在相应位置作答。
Then the idea came to me: I could appeal to my fellow divers to take action． I decided to take it a step further to try and stop those companies producing single use plastics．

Now the last news of this hour． A female dolphin washed up on Florida's Fort Myers Beach on Tuesday， according to local news station WFLA． Rescue workers had tried to save the young animal， but she was in such poor health that wildlife officials decided to kill her in a painless way． On Friday， photos of the dolphin's stomach contents were posted on the Internet， showing she had eaten two plastic bags along with a piece of a balloon． While officials noted the stomach contents were an important finding， they said it was as yet unclear what exactly caused the dolphin's illness． Even so， the post said that the presence of the bags and balloons shows the need to reduce single use plastic． Reports of sea animals found with plastic in their stomachs are becoming common． In March， 2019， a pregnant whale washed up dead off the coast of Italy with 49 pounds of plastic in her stomach． The same month， a beached whale found dead on the shores of the Philippines had 88 pounds of plastic in its stomach， including many plastic bags． Thank you for your listening． What comes next is Health Time．

On Scotland's west coast is the Firth of Clyde， a large home to thousands of porpoises (鼠海豚) and one dolphin named Kylie． Kylie hasn't been observed with other common dolphins in at least 14 years—but she's far from alone． On clear days in the Clyde， visitors to the marina can sometimes see Kylie swimming with porpoises， which are about two thirds her size．
New research suggests Kylie's ties to porpoises are closer than scientists imagined． While a common dolphin's vocal (发声的) ability should include a diverse range of clicks， whistles， and etc．， Kylie doesn't whistle． Instead， she “talks” more like porpoises， which communicate using high bursts of clicks．
“The study suggests that she may be communicating with the porpoises， or at least attempting to． It's part of a growing body of work that shows a rich world of interactions between different species of dolphins． Clearly， species in the wild interact much more than we thought，” says dolphin behavior expert Denise Herzing．
To learn more about Kylie's relationship with the porpoises， scientists borrowed a device (装置) to record sounds of Kylie and porpoises when they met each other from 2016 to 2018． “She's definitely identified as a porpoise，” says Nairn， who trained as a sea biologist in college． Researchers also studied thousands of dolphins clicks from the recordings carefully．
While dolphins whistle very often， porpoises never do． Instead， they communicate with what are called narrow band， high frequency (NBHF) clicks． To hear an NBHF click you have to play it about one hundred times slower．
Ever since February， Kylie has been missing． Nairn says he can't help but worry． Nairn and his colleagues say they're eager to look for and listen to Kylie as soon as the spring field season begins—and see what else she might teach us．
篇章导读：本文是一篇说明文。文章介绍了科学家们对一只普通的海豚Kylie (凯莉)和一群鼠海豚的关系的研究。

If someone asked you to name a species in need of conservation， it wouldn't take long for you to land upon the polar bear． As the most symbolic animal of the Arctic， polar bears perfectly adapt to such a tough environment． Although most are born on land， polar bears spend the majority of their lives around water and on the sea ice of the Arctic Ocean． While they are not facing upcoming extinction， the destruction (破坏) caused to their habitats by climate change puts their long term survival at risk and their numbers are predicted to decline by 30% by 2050．
It is estimated that there are 26，000 polar bears in the wild， living across countries that border the Arctic Ocean． They are excellent swimmers， able to reach a top speed of 6 mph． They have been known to travel areas of up to 600，000 sq km to find their prey (猎物)． Polar bears have an incredibly well developed sense of smell and can discover prey up to 1 km away．
The Arctic is warming twice as fast as the global average melting the sea ice that is vital to the polar bears' ability to find food． The polar bear's food supply is directly impacted by the melting ice． Seals， their main meal， also breed on the ice． So the whole seal population dwindles too as a consequence of that change． And it has forced polar bears to look further for seals． This has increased conflict between humans and polar bears， as they come closer to human settlements looking for food．
The fight to save polar bears is in fact linked to the joint efforts of us humans． There are several organisations aimed to aid polar bears． Polar Bears International is the only conservation group aimed to help polar bears． Consisting of scientists and conservationists， they are expanding our knowledge about polar bear using the most advanced technology． Another is the International Association for Bear Research and Management (IBA)， a group with over 500 members from over 60 countries who work together to share research and information on eight bear species including the polar bear．

The ocean， with its vast mysteries hidden in its depths， has long excited human curiosity． From ancient maps decorated with dragons and sea monsters to modern day technology， we've made limited progress in uncovering the secrets of the deep blue． Despite the technological advancements to date， only around five percent of the world's oceans have been mapped．
The power of underwater exploration is currently the biggest obstacle we face． While technologies like wave and tidal power show promise， they are often location dependent． Solar power， on the other hand， offers an ever present and powerful energy source， even beneath the ocean's surface． Sunlight can penetrate (穿透) waters up to 50 meters deep， providing sufficient energy to operate basic appliances． And in recent research conducted by a team from NYU Tandon School of Engineering， solar cells successfully powered AUVs (autonomous underwater vehicles) and communications equipment， demonstrating its enormous potential for undersea exploration．
However， some challenges remain． One lies in the design of existing silicon (硅) solar technology， which is ill suited for underwater environments． Beyond moisture and salt content harmful to electronics in general， silicon solar cells are optimized (使优化) to absorb red and infrared light， which do not penetrate water effectively．
Another critical issue underwater solar cells face is biofouling—the gradual gathering of organic substances on the cells． This buildup blocks light． Furthermore， it affects the underwater vehicles themselves， increasing their weight． Previous experiments revealed that biofouling covered over 50 percent of the surface after just 30 days underwater， significantly hampering solar cell operation．
In the research， the team also tackled practical challenges in designing and testing underwater solar cells． They created innovative solutions， such as using LED lights to copy the light spectrum (光谱) at various depths， removing the need for water during testing．
These experiments demonstrated that silicon based solar cells performed better in shallow depths， while other cell types proved more efficient below two meters． Although these specially designed underwater solar cells are still in their early stages of development， these contributions could lay the foundations for groundbreaking technologies that reveal both the potential of solar energy and the mysterious depths of our unexplored oceans．

In 1999， journalist Nicholas D．Kristof reported a surprising encounter on a tiny African island． Here， Kristof met a number of elderly men who told him that they were descendants of Chinese sailors many centuries ago． Their ancestors had traded with local Africans， who had given them giraffes to take back to China． __36__
Six centuries ago， a large number of Chinese ships crossed the sea， then travelled west to East Africa． __37__ These seven great expeditions brought a vast web of trading links under Chinese government control．
__38__ Most of the trading involved spices (香料)， wood， and medicines． Zheng He brought them back to the capital． Although these goods were mainly presented to the emperor for his consumption and disposal， foreign ambassadors who came to China were permitted to trade with locals in the capital for handsome profits， which also allowed ordinary Chinese to benefit from international trade．
__39__ In the regions they visited， Zheng He and his fleet (船队) remained a long lasting theme in popular Southeast Asia folk tales． Two surviving records of the expeditions provide detailed accounts of unique Chinese navigation technologies of the time， leaving Chinese rich maritime legacy (遗产) to later generations．
However， the Chinese expedition never sought to establish colonial rule over these oceans by military force． __40__ China's maritime dominance disappeared suddenly in the 1430s because of domestic changes， and the overseas expeditions were eventually ended by the court． All this happened only decades prior to the occurrence of the great age of European discovery and exploration．
A．Seven times， the treasure fleets set off for the unknown．
B．Zheng He's great voyage started at the port of Nanjing．
C．Aside from the economic impact， there was more cultural print．
D．The actual economic impact of the expedition was difficult to evaluate．
E．Zheng He traded China's products for foreign luxuries and daily products．
F．It was intended to facilitate international and trade relationships with others．
G．If it's true， this remote village is evidence of an astonishing episode of maritime exploration in China．

Protecting Our Ocean
Good morning， everyone! It is such a privilege to stand here to share with you my perspectives on the ocean． As the cradle of life， oceans nurture thousands of creatures and provide us with abundant seafood and energy． However， the ocean is facing threats．
Definitely， pollution is the one that threatens the ocean most． For decades the ocean has been used as a receptacle for industrial waste． Plus， overfishing has posed a threat to the fragile ecosystem of the ocean． To tackle the crisis， joint efforts from all countries are needed， from establishing related policies to promoting people's awareness． Besides， we students can do our part by reducing disposable plastics， which are a great contributing factor to the damage to the ocean．
In conclusion， for a sustainable future， we should care for the ocean． Together we can make a difference． Thank you．
第二节(满分25分)
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
A couple of years ago， I had the pleasure of teaching a young couple to dive (潜水) in Thailand on one of my favorite reefs (礁)． The weather conditions were perfect， with mild currents and excellent sight of the beautiful ocean and the bright， vivid corals． Even with their masks on， I could see the smiles on my students' faces．
The dive couldn't have gone better． However， things changed as we made our way back to the boat． As we swam back along the reef， I noticed the current (水流) changing． As it did， huge quantities of trash and plastic began to flood the area． I saw small reef fish swimming amongst the straws， plastic bags and other bits of rubbish． I noticed that some of the fish were pecking away (啄) at the plastic． By the time we got back on board the boat， there were bits of plastic floating all around us． It looked more like a trash site than the ocean．
When I got home， the first thing I did was to go online and research plastic pollution in the ocean． I was surprised to find out that over the past decade， divers and beach lovers have seen a lot of changes in the oceans． Even very remote locations were suddenly filled with plastic and other chemicals． Plastics were entering our oceans at an alarming rate—up to 12 million tons each year． This huge amount of plastic was wreaking havoc (破坏) not only on the environment， but also on the marine animals that lived in the ocean， such as sea turtles and sea birds． Some of them were sadly mistaking the pieces of plastic for food． Pollution has brought our oceans to the point of disaster， and unless we make a great change， then our oceans and all of its living things， will be at risk．
Since that unforgettable plastic polluted dive， I have become an ocean supporter and spend my days trying to get the message out there about just how harmful ocean pollution is， not only to marine life， but also to mankind．
注意：
1．续写词数应为150个左右；
2．请按如下格式在相应位置作答。
Then the idea came to me: I could appeal to my fellow divers to take action． I decided to take it a step further to try and stop those companies producing single use plastics．
写前导读：本文是一篇记叙文。几年前作者在泰国教一对年轻的夫妇潜水时，发现海洋中出现了大量的垃圾和塑料。作者想要呼吁潜水者一起行动，他会得到大家的支持吗？作者又会如何进一步阻止公司生产一次性塑料呢？
[精彩范文]
Then the idea came to me: I could appeal to my fellow divers to take action． I reached out to the local divers， who immediately started supporting me． The following months saw us collecting pieces of plastic that we saw floating past and putting them in the pocket of our diving suits． If we were walking along the beach， we made sure to collect all the plastic that we saw on the sand． The effects were noticeable almost immediately． I could see the beach returning to its original beauty． However， I knew that these individual actions weren't enough to stop the concerning plastic pollution crisis unless companies stopped producing so much plastic in the first place．
I decided to take it a step further to try and stop those companies producing single use plastics． One way in particular stood out because it was easy to implement， yet its effects would be far reaching． Whenever I found a piece of branded plastic waste in the ocean， on a river bank or beach， I took a picture of it and posted it to social media， tagged the brand， and used the hashtag Is This Yours Since I started this approach， I have reached out to a dozen companies in this way and got more and more enthusiastic followers． We may be limited in what we can do， but I believe that a single spark can start a prairie fire．

Now the last news of this hour． A female dolphin washed up on Florida’s Fort Myers Beach on Tuesday， according to local news station WFLA． Rescue workers had tried to save the young animal， but she was in such poor health that wildlife officials decided to kill her in a painless way． On Friday， photos of the dolphin’s stomach contents were posted on the Internet， showing she had eaten two plastic bags along with a piece of a balloon． While officials noted the stomach contents were an important finding， they said it was as yet unclear what exactly caused the dolphin’s illness．
Even so， the post said that the presence of the bags and balloons shows the need to reduce single use plastic． Reports of sea animals found with plastic in their stomachs are becoming common． In March， 2019， a pregnant whale washed up dead off the coast of Italy with 49 pounds of plastic in her stomach． The same month， a beached whale found dead on the shores of the Philippines had 88 pounds of plastic in its stomach， including many plastic bags． Thank you for your listening． What comes next is Health Time．
18．What did wildlife officials decide to do with the washed up dolphin
A．Clear her stomach． B．Put her back to the sea．
C．Kill her in a painless way．
19．What was still unknown yet
A．Why the dolphin got sick． B．Whether the dolphin was pregnant．
C．What was in the dolphin’s stomach．
20．Where is the talk probably being given
A．In a lecture hall． B．At a radio studio．
C．On the beach．

On Scotland's west coast is the Firth of Clyde， a large home to thousands of porpoises (鼠海豚) and one dolphin named Kylie． Kylie hasn't been observed with other common dolphins in at least 14 years—but she's far from alone． On clear days in the Clyde， visitors to the marina can sometimes see Kylie swimming with porpoises， which are about two thirds her size．
New research suggests Kylie’s ties to porpoises are closer than scientists imagined． While a common dolphin’s vocal (发声的) ability should include a diverse range of clicks， whistles， and etc．， Kylie doesn’t whistle． Instead， she “talks” more like porpoises， which communicate using high bursts of clicks．
“The study suggests that she may be communicating with the porpoises， or at least attempting to． It's part of a growing body of work that shows a rich world of interactions between different species of dolphins． Clearly， species in the wild interact much more than we thought，” says dolphin behavior expert Denise Herzing．
To learn more about Kylie’s relationship with the porpoises， scientists borrowed a device (装置) to record sounds of Kylie and porpoises when they met each other from 2016 to 2018． “She’s definitely identified as a porpoise，” says Nairn， who trained as a sea biologist in college． Researchers also studied thousands of dolphins clicks from the recordings carefully．
While dolphins whistle very often， porpoises never do． Instead， they communicate with what are called narrow band， high frequency (NBHF) clicks． To hear an NBHF click you have to play it about one hundred times slower．
Ever since February， Kylie has been missing． Nairn says he can’t help but worry． Nairn and his colleagues say they’re eager to look for and listen to Kylie as soon as the spring field season begins—and see what else she might teach us．
篇章导读：本文是一篇说明文。文章介绍了科学家们对一只普通的海豚Kylie (凯莉)和一群鼠海豚的关系的研究。

If someone asked you to name a species in need of conservation， it wouldn’t take long for you to land upon the polar bear． As the most symbolic animal of the Arctic， polar bears perfectly adapt to such a tough environment． Although most are born on land， polar bears spend the majority of their lives around water and on the sea ice of the Arctic Ocean． While they are not facing upcoming extinction， the destruction (破坏) caused to their habitats by climate change puts their long term survival at risk and their numbers are predicted to decline by 30% by 2050．
It is estimated that there are 26，000 polar bears in the wild， living across countries that border the Arctic Ocean． They are excellent swimmers， able to reach a top speed of 6 mph． They have been known to travel areas of up to 600，000 sq km to find their prey (猎物)． Polar bears have an incredibly well developed sense of smell and can discover prey up to 1 km away．
The Arctic is warming twice as fast as the global average melting the sea ice that is vital to the polar bears’ ability to find food． The polar bear’s food supply is directly impacted by the melting ice． Seals， their main meal， also breed on the ice． So the whole seal population dwindles too as a consequence of that change． And it has forced polar bears to look further for seals． This has increased conflict between humans and polar bears， as they come closer to human settlements looking for food．
The fight to save polar bears is in fact linked to the joint efforts of us humans． There are several organisations aimed to aid polar bears． Polar Bears International is the only conservation group aimed to help polar bears． Consisting of scientists and conservationists， they are expanding our knowledge about polar bear using the most advanced technology． Another is the International Association for Bear Research and Management (IBA)， a group with over 500 members from over 60 countries who work together to share research and information on eight bear species including the polar bear．

The ocean， with its vast mysteries hidden in its depths， has long excited human curiosity． From ancient maps decorated with dragons and sea monsters to modern day technology， we’ve made limited progress in uncovering the secrets of the deep blue． Despite the technological advancements to date， only around five percent of the world’s oceans have been mapped．
The power of underwater exploration is currently the biggest obstacle we face． While technologies like wave and tidal power show promise， they are often location dependent． Solar power， on the other hand， offers an ever present and powerful energy source， even beneath the ocean’s surface． Sunlight can penetrate (穿透) waters up to 50 meters deep， providing sufficient energy to operate basic appliances． And in recent research conducted by a team from NYU Tandon School of Engineering， solar cells successfully powered AUVs (autonomous underwater vehicles) and communications equipment， demonstrating its enormous potential for undersea exploration．
However， some challenges remain． One lies in the design of existing silicon (硅) solar technology， which is ill suited for underwater environments． Beyond moisture and salt content harmful to electronics in general， silicon solar cells are optimized (使优化) to absorb red and infrared light， which do not penetrate water effectively．
Another critical issue underwater solar cells face is biofouling—the gradual gathering of organic substances on the cells． This buildup blocks light． Furthermore， it affects the underwater vehicles themselves， increasing their weight． Previous experiments revealed that biofouling covered over 50 percent of the surface after just 30 days underwater， significantly hampering solar cell operation．
In the research， the team also tackled practical challenges in designing and testing underwater solar cells． They created innovative solutions， such as using LED lights to copy the light spectrum (光谱) at various depths， removing the need for water during testing．
These experiments demonstrated that silicon based solar cells performed better in shallow depths， while other cell types proved more efficient below two meters． Although these specially designed underwater solar cells are still in their early stages of development， these contributions could lay the foundations for groundbreaking technologies that reveal both the potential of solar energy and the mysterious depths of our unexplored oceans．
篇章导读：本文是一篇新闻报道。文章主要报道了海洋深处巨大的奥秘以及人类对于利用太阳能进行水下探索的尝试和面临的挑战。
32．What does the author intend to tell us in Paragraph 1
A．The ocean is mostly unexplored．
B．The sea has shaped human civilization．
C．Marine exploration technology is urgently needed．
D．Technology promotes humans’ underwater exploration．

33．What is the advantage of solar power according to Paragraph 2
A．It is affordable．
B．It is eco friendly．
C．It is location independent．
D．It is efficient in generating electricity．
解析：细节理解题。根据第二段中的“Solar power ... the ocean's surface．”可知，太阳能甚至在海洋表面以下也会提供一种始终存在的强大能源，因此，太阳能的优势是不受地点限制。故选C。
34．What is the author's attitude towards the underwater solar cells designed by the researchers
A．Unconcerned． B．Favorable．
C．Doubtful． D．Disapproving．
解析：推理判断题。根据最后一段中的“Although these specially ... our unexplored oceans．”可知，作者认为水下太阳能电池可以为突破性技术奠定基础，揭示太阳能的潜力和我们未探索的海洋的神秘深度，由此可推知，作者对研究人员设计的水下太阳能电池持赞许态度。故选B。
35．In which section of a magazine may this text appear
A．Health． B．Education．
C．Society． D．Nature．
解析：推理判断题。通读全文可知，本文主要介绍了海洋深处巨大的奥秘以及人类对于利用太阳能进行水下探索的尝试和所面临的挑战。由此可推知，本文可能出现在杂志的自然板块。故选D。
第二节(共5小题；每小题2．5分，满分12．5分)
阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选项。选项中有两项为多余选项。
In 1999， journalist Nicholas D．Kristof reported a surprising encounter on a tiny African island． Here， Kristof met a number of elderly men who told him that they were descendants of Chinese sailors many centuries ago． Their ancestors had traded with local Africans， who had given them giraffes to take back to China． __36__
Six centuries ago， a large number of Chinese ships crossed the sea， then travelled west to East Africa． __37__ These seven great expeditions brought a vast web of trading links under Chinese government control．
__38__ Most of the trading involved spices (香料)， wood， and medicines． Zheng He brought them back to the capital． Although these goods were mainly presented to the emperor for his consumption and disposal， foreign ambassadors who came to China were permitted to trade with locals in the capital for handsome profits， which also allowed ordinary Chinese to benefit from international trade．
__39__ In the regions they visited， Zheng He and his fleet (船队) remained a long lasting theme in popular Southeast Asia folk tales． Two surviving records of the expeditions provide detailed accounts of unique Chinese navigation technologies of the time， leaving Chinese rich maritime legacy (遗产) to later generations．
However， the Chinese expedition never sought to establish colonial rule over these oceans by military force． __40__ China’s maritime dominance disappeared suddenly in the 1430s because of domestic changes， and the overseas expeditions were eventually ended by the court． All this happened only decades prior to the occurrence of the great age of European discovery and exploration．
A．Seven times， the treasure fleets set off for the unknown．
B．Zheng He's great voyage started at the port of Nanjing．
C．Aside from the economic impact， there was more cultural print．
D．The actual economic impact of the expedition was difficult to evaluate．
E．Zheng He traded China's products for foreign luxuries and daily products．
F．It was intended to facilitate international and trade relationships with others．
G．If it’s true， this remote village is evidence of an astonishing episode of maritime exploration in China．
篇章导读：本文是一篇说明文。文章介绍了郑和下西洋的经济、文化和政治意义。
36．答案： G
解析：上文“In 1999， journalist Nicholas D．Kristof ... take back to China．”讲述了记者在非洲一个小岛上遇到一些老人，他们说自己是中国水手的后代，并讲述他们祖先与非洲人贸易的故事；下文讲述了中国古代的海上探险(郑和下西洋)，由此可知，G项(如果这是真的，这个偏远的村庄就是中国海上探险的证据。)将上文非洲小岛上的偶遇与郑和下西洋联系衔接起来。故选G。
37．答案：A
解析：根据下文“These seven great ... government control．”中的“These seven great expeditions”可知，设空处应提到七次探险，A项(宝船队七次启程前往未知的地方。)引出下文，符合语境。故选A。
38．答案：E

Protecting Our Ocean
Good morning， everyone! It is such a privilege to stand here to share with you my perspectives on the ocean． As the cradle of life， oceans nurture thousands of creatures and provide us with abundant seafood and energy． However， the ocean is facing threats．
Definitely， pollution is the one that threatens the ocean most． For decades the ocean has been used as a receptacle for industrial waste． Plus， overfishing has posed a threat to the fragile ecosystem of the ocean． To tackle the crisis， joint efforts from all countries are needed， from establishing related policies to promoting people's awareness． Besides， we students can do our part by reducing disposable plastics， which are a great contributing factor to the damage to the ocean．
In conclusion， for a sustainable future， we should care for the ocean． Together we can make a difference． Thank you．
第二节(满分25分)
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。
A couple of years ago， I had the pleasure of teaching a young couple to dive (潜水) in Thailand on one of my favorite reefs (礁)． The weather conditions were perfect， with mild currents and excellent sight of the beautiful ocean and the bright， vivid corals． Even with their masks on， I could see the smiles on my students’ faces．
The dive couldn’t have gone better． However， things changed as we made our way back to the boat． As we swam back along the reef， I noticed the current (水流) changing． As it did， huge quantities of trash and plastic began to flood the area． I saw small reef fish swimming amongst the straws， plastic bags and other bits of rubbish． I noticed that some of the fish were pecking away (啄) at the plastic． By the time we got back on board the boat， there were bits of plastic floating all around us． It looked more like a trash site than the ocean．
When I got home， the first thing I did was to go online and research plastic pollution in the ocean． I was surprised to find out that over the past decade， divers and beach lovers have seen a lot of changes in the oceans． Even very remote locations were suddenly filled with plastic and other chemicals． Plastics were entering our oceans at an alarming rate—up to 12 million tons each year． This huge amount of plastic was wreaking havoc (破坏) not only on the environment， but also on the marine animals that lived in the ocean， such as sea turtles and sea birds． Some of them were sadly mistaking the pieces of plastic for food． Pollution has brought our oceans to the point of disaster， and unless we make a great change， then our oceans and all of its living things， will be at risk．
Since that unforgettable plastic polluted dive， I have become an ocean supporter and spend my days trying to get the message out there about just how harmful ocean pollution is， not only to marine life， but also to mankind．
注意：
1．续写词数应为150个左右；
2．请按如下格式在相应位置作答。
Then the idea came to me: I could appeal to my fellow divers to take action． ﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍
I decided to take it a step further to try and stop those companies producing single use plastics． ﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍
写前导读：本文是一篇记叙文。几年前作者在泰国教一对年轻的夫妇潜水时，发现海洋中出现了大量的垃圾和塑料。作者想要呼吁潜水者一起行动，他会得到大家的支持吗？作者又会如何进一步阻止公司生产一次性塑料呢？
[精彩范文]
Then the idea came to me: I could appeal to my fellow divers to take action． I reached out to the local divers， who immediately started supporting me． The following months saw us collecting pieces of plastic that we saw floating past and putting them in the pocket of our diving suits． If we were walking along the beach， we made sure to collect all the plastic that we saw on the sand． The effects were noticeable almost immediately． I could see the beach returning to its original beauty． However， I knew that these individual actions weren't enough to stop the concerning plastic pollution crisis unless companies stopped producing so much plastic in the first place．
I decided to take it a step further to try and stop those companies producing single use plastics． One way in particular stood out because it was easy to implement， yet its effects would be far reaching． Whenever I found a piece of branded plastic waste in the ocean， on a river bank or beach， I took a picture of it and posted it to social media， tagged the brand， and used the hashtag Is This Yours Since I started this approach， I have reached out to a dozen companies in this way and got more and more enthusiastic followers． We may be limited in what we can do， but I believe that a single spark can start a prairie fire．
