Unit 5 Into the unknown
第一部分 阅读理解（共两节，满分50分）
第一节 （共15小题；每小题2.5分，满分37.5分）
阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
A
The UK physicist Isaac Newton once said, "Nature is pleased with simplicity and nature is no dummy (傻子)." Indeed, Mother Nature can provide almost everything human beings need if we follow her rules. But if we break the rules, she is likely to be cruel and lash out at (抨击)us.
The outbreak of COVID-19 in China and some other countries at the beginning of this year is an example. According to some experts, the novel coronavirus is similar to a virus found in a bat in 2017 and probably has an intermediate host(中间宿主).
It's once believed that the virus originated from the Huanan Seafood Market in Wuhan, Hubei Province, where live wild animals were sold.
The Wall Street Journal reported that Dr. Peter Daszak, president of the US-based health organization EcoHealth Alliance, said, "This outbreak is a lesson to us. On a global scale(规模), human population density (密度), wildlife diversity, and land use change are what drive new pandemics (流行病)."
In ancient times, people needed to rely on nature to survive so they held it in awe (敬畏). For example, the American Indians believed that humans are a part of nature and nature is a part of humans.' Ancient Chinese people always pursued the harmony between nature and human beings. However, as human beings master more knowledge and make more advanced tools, people try to change and even conquer nature. They use more land to make buildings, genetically modify(改变) plants, capture some wild and rare animals to suit their own needs. In this process, humans gradually lose contact with nature and even throw it out of balance. For example, cutting a large number of forests means carbon dioxide must build up in the atmosphere and it contributes to global warming.
Although we don't know for sure what first caused the COVID-19 outbreak, Brian Lamacraft said it's time to "reflect on our relationship with our planet" and "reconnect with this world and everything that we've been given". After all, according to the US poet Gary Snyder, "Nature is not the place to visit. It's our home."
1.What lesson did Daszak think human beings should learn from the COVID-19 outbreak
A.Bats are one of the most dangerous wild animals.
B.It's impossible to prevent new pandemics globally.
C.We should stop the wildlife trade around the world.
D.Humans should live peacefully with nature.
2.What is the main idea of Paragraph 5
A.How human beings become their own masters.
B.How human activities cause global warming.
C.How human beings break the balance of nature.
D.How humans use technology to improve their lives.
3.What is the author's purpose of writing this article
A.To reflect on the COVID-19 outbreak.
B.To explain what led to the COVID-19 outbreak.
C.To describe experts' predictions on new pandemics.
D.To compare ancient and modern attitudes towards nature.

For those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity.
Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.
To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men's fitness and resting(新陈代谢的) rates and took samples(样品) their blood and fat tissue.
Then, on two separate morning visits to the scientists' lab, each man walked for an hour at an average speed that, in theory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast(禁食期). On the other occasion, they ate a rich morning meal about two hours before they started walking.
Just before and an hour after each workout, the scientists took additional samples of the men's blood and fat tissue.
Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories(卡路里), on average, during the workout after breakfast than after fasting.
But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin(胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.
The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.

I believe in the power of science fiction, not only for its capacity to transform dreams into reality, but also for its power of bonding together those who share a common vision of the future. For me, that's true for my relationship with my dad. Some fathers and sons bond over sports, fishing or hunting, but my dad and I bond over Star Trek. We tried a trip to Walt Disney World, but one of my earliest memories wasn't Mickey, but a Klingon battle cruiser(战列巡洋舰) on the screen.
Over the years, nearly every setting and situation has become far away for my dad and me. When it's warm at night, we're not driving along some dark streets in Indiana, but walking at slow speed with stars dimly shining. Both of us are thinking of them, without needing to say a word. All these visions of other universes have together created a private universe for my dad and me.
Gene Roddenberry, creator of Star Trek, once said, "Science fiction is a way of thinking, a way of logic that bypasses(绕过) a lot of nonsense. It allows people to look directly at important subjects." A lifetime of science fiction has influenced more than just my relationship with my dad, but has also helped me shape my own hopes for the future. I'm now a science writer.
Yes, science fiction has made me into a "nerd(书呆子)", and it also has been a source of joy for my family, making me an optimist while enabling me to think critically about the danger of technology. Thank those authors who have shared their visions; the world and my family are better for it. Thank my dad, who is both the best storyteller and the best man I have ever known because he helped me realize the truth of Tennyson's words, "Since I dipped into the future, I saw the vision of the world, and all the wonders that would be."
1.What is the special bond between the author and his father
A.Their similar dreams. B.Their love for each other.

2.What does the author mainly show in Paragraph 2
A.His deep impression of his dad. B.His feeling of staying with his dad.
C.His earliest memory of his dad. D.His good relationship with his dad.
3.How does science fiction help the author at present
A.It leads him to pursue a desirable career. B.It brings him the courage to live better.
C.It helps him sense the danger of technology. D.It makes him become a source of his family's joy.

It's always nice to have a little help around the house. But what if you could employ the assistance of one of the greatest minds of the 20th century
That's the idea behind a new robot modelled after Albert Einstein. Called Professor Einstein and standing just over a foot tall, this personal assistant can tell you the weather and keep track of your schedule like any other robot. With built-in Wi-Fi, Einstein robot has access to puzzles, and can answer maths problems and science questions. With natural language speech processing, you can actually interact with Professor Einstein. And because the robot is connected to the Internet, it is constantly updated with new information.
To help get the perfect replica(复制品) of Einstein, the Hong Kong-based tech company Hanson Robotics turned to the Hebrew University of Jerusalem, the home of the Albert Einstein Archives(档案馆). "We worked very closely with it to bring the product onto the market," the company's Dr Jeanne Lim said.
Einstein robot was introduced to the public at the Consumer Electronics Show in Las Vegas and was quickly hailed by those who saw it. "He became one of the breakout stars of the convention," wrote Melia Robinson on Business Insider. "Crowds flooded into the company to have a look at the little guy."
"Technology is often now very cold and socially isolated(孤立的)," explained David Hanson, the cofounder of the company behind the new robot. "By bringing a lively character into our physical world, we're humanizing(使人性化) the technology instead of dehumanizing the humans."
As for Hanson Robotics, the company has been building human-sized robots for over a decade. But this marks the company's first commercially available product. "Professor Einstein is just the start," said Hanson. "We're witnessing the arrival of conversational robots that can walk in our world. It's a golden age of invention."
1.What can Einstein robot do
A.Teach you to learn any new language. B.Have a regular conversation with you.
C.Design a number of science questions. D.Keep track of other robots constantly.
2.Which of the following best explains "hailed" underlined in Paragraph 4
A.Broken. B.Improved. C.Ignored. D.Praised.
3.What can be inferred from David Hanson's words
A.He expects humans to be less isolated from robots.
B.He dreams of humanizing humans through invention.
C.He worries about a golden age of conversational robots.
D.He stays hopeful about the future of robot invention.
4.What can be a suitable title for the text
A.A New Robot Makes Humans Much Happier B.The Golden Age of Invention Is Approaching
C.Albert Einstein "Changes" Into an Assistant D.Albert Einstein Helps to Humanize Robots

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Music is an art form which deals with the representation of emotion through the medium of sound. It can have a physical effect on us because it is closely linked with emotion, perhaps even more than the abstract words. The first reason why people listen to music is to adjust their emotional slate. ①_____
Numerous studies show us that there's no doubt that music can affect our mood state and stress level. ②_____ For example, they have found that background music shuts out distractions. It calms them before a large task and then they can stay focused for longer. Also, it can help their creativity and make studying more enjoyable.
③_____ Firstly, it depends on what the task is. The more difficult the challenge is, the more likely background music will interrupt the learning process. For less challenging learning tasks, music can greatly assist in providing a positive learning state. Secondly, it depends on the characteristics of the music we'll come to in a moment. And thirdly, extroverts (性格外向者) enjoy and often require more external stimulation (刺激) and are likely to handle background noise better than those who are quiet and shy.
Actually, it's not the genre (类型) of music, but the natural musical characteristics that aid or disrupt study. One of these characteristics is the tempo (拍子). The recommended tempo for background music is in the range of 70 to 110 beats per minute, slightly faster than the heartbeat when we are at rest. ④_____ And very slow music lowers the heartbeat, creating a state that might be too relaxed for study purposes.
In addition, lyrics (歌词) are the most distracting aspect of listening to background music. ⑤_____ More particularly, studies have found that the most distracting background music is fast and familiar vocal music, chosen and liked by the listener.
A. Music is part of every culture in the world.
B. In a very real sense, music connects us with our inner selves.
C. Music, like language, is a unique human form of communication.
D. They compete with the same brain regions that process language.
E. Fast music raises the heartbeat, making one unable to focus on study.
F. There are a few factors that determine the effects of music on studying.
G. Moreover, those who like studying with background music have found a lot of benefits.

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。
Ten-year-old Sam loved to visit his grandfather's house. The house was near the beautiful blue sea. At the seaside stood thick and tall palm trees with coconuts hanging from them. When the coconuts fell down, Sam would break them open and drink the coconut juice. Sam liked to play under the trees. It was always great fun to spend the holidays at Grandpa's place.
This winter vacation, Sam was surprised when he came to his grandfather's village. There were hardly any trees left. He saw houses built near the sea. People had cut down many palm trees and there was hardly any greenery left.
Grandpa's house was different. He never allowed his trees to be cut. He hugged each palm tree in his courtyard. He also named the two big trees near the front door—one was Petu, and the other Betu. He had planted them with his own hands and today they had become large, massive trees with thick trunks. They were tall and green and gave the sweetest, juiciest coconuts.
One night, Sam was awakened by a strange sound. He could not sleep. He tossed and turned (辗转反侧) in bed. Suddenly, the ground began shaking as if the earth was splitting. He sat up straight and then ran to Grandpa. He clung (附着) to his grandpa. Grandpa cried out, "It's an earthquake! It's an earthquake!" They ran outside the house. They thought that it would be safer there.
Suddenly, there was a loud sound; the earth was not splitting but the sea was roaring. People were shouting, screaming and crying, "The sea is rising! The sea is rising!" The villagers started running away from the beach. Sam was dumbstruck (呆若木鸡).
The waves were rising higher and higher. Sam thought, "How big the waves are!" He went into the house again and saw water coming in from all sides. He was scared.
Sam remembered his mother telling him long ago, "You must always get out of the house if the floods come too near." So he ran out to be with Grandpa.
Waves about twelve meters high came rushing in, drowning everything. Water was all around and everywhere.

第二节
答案： Grandpa held Sam's hand tightly but a huge wave separated them. Grandpa fought the waves and strived to catch Sam, but failed. Sam was washed away! Grandpa struggled to keep his head above the water. The water pushed him ahead. Fortunately, he caught a palm tree in his courtyard. He panicked and screamed out at Sam but could not see him. He clung to the tree tightly while the water was all around. In the hope of seeing Sam, Grandpa climbed higher up the tree. The water carried Sam round and round.
"Sam! Sam!" cried Grandpa. "Don't be scared, little e to me, quickly!" "But Grandpa, I can't swim!" Another wave came with terrifying speed and force. Sam cried in despair. Suddenly, Sam felt himself thrown onto the top of a tree. He immediately held it! Looking around, he saw everything was terribly destroyed; but in the near distance, Grandpa was in another tree! Soon it was calm; both Grandpa and Sam came down from the trees and rushed to hug each other, and then they hugged the trees with tears of gratitude.

The UK physicist Isaac Newton once said, "Nature is pleased with simplicity and nature is no dummy (傻子)." Indeed, Mother Nature can provide almost everything human beings need if we follow her rules. But if we break the rules, she is likely to be cruel and lash out at (抨击)us.
The outbreak of COVID-19 in China and some other countries at the beginning of this year is an example. According to some experts, the novel coronavirus is similar to a virus found in a bat in 2017 and probably has an intermediate host(中间宿主).
It's once believed that the virus originated from the Huanan Seafood Market in Wuhan, Hubei Province, where live wild animals were sold.
The Wall Street Journal reported that Dr. Peter Daszak, president of the US-based health organization EcoHealth Alliance, said, "This outbreak is a lesson to us. On a global scale(规模), human population density (密度), wildlife diversity, and land use change are what drive new pandemics (流行病)."
In ancient times, people needed to rely on nature to survive so they held it in awe (敬畏). For example, the American Indians believed that humans are a part of nature and nature is a part of humans.' Ancient Chinese people always pursued the harmony between nature and human beings. However, as human beings master more knowledge and make more advanced tools, people try to change and even conquer nature. They use more land to make buildings, genetically modify(改变) plants, capture some wild and rare animals to suit their own needs. In this process, humans gradually lose contact with nature and even throw it out of balance. For example, cutting a large number of forests means carbon dioxide must build up in the atmosphere and it contributes to global warming.
Although we don't know for sure what first caused the COVID-19 outbreak, Brian Lamacraft said it's time to "reflect on our relationship with our planet" and "reconnect with this world and everything that we've been given". After all, according to the US poet Gary Snyder, "Nature is not the place to visit. It's our home."
1.What lesson did Daszak think human beings should learn from the COVID-19 outbreak
A.Bats are one of the most dangerous wild animals.
B.It's impossible to prevent new pandemics globally.
C.We should stop the wildlife trade around the world.
D.Humans should live peacefully with nature.
2.What is the main idea of Paragraph 5
A.How human beings become their own masters.
B.How human activities cause global warming.
C.How human beings break the balance of nature.
D.How humans use technology to improve their lives.
3.What is the author's purpose of writing this article
A.To reflect on the COVID-19 outbreak.
B.To explain what led to the COVID-19 outbreak.

For those who can stomach it, working out before breakfast may be more beneficial for health than eating first, according to a study of meal timing and physical activity.
Athletes and scientists have long known that meal timing affects performance. However, far less has been known about how meal timing and exercise might affect general health.
To find out, British scientists conducted a study. They first found 10 overweight and inactive but otherwise healthy young men, whose lifestyles are, for better and worse, representative of those of most of us. They tested the men's fitness and resting(新陈代谢的) rates and took samples(样品) their blood and fat tissue.
Then, on two separate morning visits to the scientists' lab, each man walked for an hour at an average speed that, in theory, should allow his body to rely mainly on fat for fuel. Before one of these workouts, the men skipped breakfast, meaning that they exercised on a completely empty stomach after a long overnight fast(禁食期). On the other occasion, they ate a rich morning meal about two hours before they started walking.
Just before and an hour after each workout, the scientists took additional samples of the men's blood and fat tissue.
Then they compared the samples. There were considerable differences. Most obviously, the men displayed lower blood sugar levels at the start of their workouts when they had skipped breakfast than when they had eaten. As a result, they burned more fat during walks on an empty stomach than when they had eaten first. On the other hand, they burned slightly more calories(卡路里), on average, during the workout after breakfast than after fasting.
But it was the effects deep within the fat cells that may have been the most significant, the researchers found. Multiple genes behaved differently, depending on whether someone had eaten or not before walking. Many of these genes produce proteins (蛋白质) that can improve blood sugar regulation and insulin(胰岛素) levels throughout the body and so are associated with improved metabolic health. These genes were much more active when the men had fasted before exercise than when they had breakfasted.
The implication of these results is that to gain the greatest health benefits from exercise, it may be wise to skip eating first.

I believe in the power of science fiction, not only for its capacity to transform dreams into reality, but also for its power of bonding together those who share a common vision of the future. For me, that's true for my relationship with my dad. Some fathers and sons bond over sports, fishing or hunting, but my dad and I bond over Star Trek. We tried a trip to Walt Disney World, but one of my earliest memories wasn't Mickey, but a Klingon battle cruiser(战列巡洋舰) on the screen.
Over the years, nearly every setting and situation has become far away for my dad and me. When it's warm at night, we're not driving along some dark streets in Indiana, but walking at slow speed with stars dimly shining. Both of us are thinking of them, without needing to say a word. All these visions of other universes have together created a private universe for my dad and me.
Gene Roddenberry, creator of Star Trek, once said, "Science fiction is a way of thinking, a way of logic that bypasses(绕过) a lot of nonsense. It allows people to look directly at important subjects." A lifetime of science fiction has influenced more than just my relationship with my dad, but has also helped me shape my own hopes for the future. I'm now a science writer.
Yes, science fiction has made me into a "nerd(书呆子)", and it also has been a source of joy for my family, making me an optimist while enabling me to think critically about the danger of technology. Thank those authors who have shared their visions; the world and my family are better for it. Thank my dad, who is both the best storyteller and the best man I have ever known because he helped me realize the truth of Tennyson's words, "Since I dipped into the future, I saw the vision of the world, and all the wonders that would be."
1.What is the special bond between the author and his father
A.Their similar dreams. B.Their love for each other.

2.What does the author mainly show in Paragraph 2
A.His deep impression of his dad. B.His feeling of staying with his dad.
C.His earliest memory of his dad. D.His good relationship with his dad.
3.How does science fiction help the author at present
A.It leads him to pursue a desirable career. B.It brings him the courage to live better.
C.It helps him sense the danger of technology. D.It makes him become a source of his family's joy.

It's always nice to have a little help around the house. But what if you could employ the assistance of one of the greatest minds of the 20th century
That's the idea behind a new robot modelled after Albert Einstein. Called Professor Einstein and standing just over a foot tall, this personal assistant can tell you the weather and keep track of your schedule like any other robot. With built-in Wi-Fi, Einstein robot has access to puzzles, and can answer maths problems and science questions. With natural language speech processing, you can actually interact with Professor Einstein. And because the robot is connected to the Internet, it is constantly updated with new information.
To help get the perfect replica(复制品) of Einstein, the Hong Kong-based tech company Hanson Robotics turned to the Hebrew University of Jerusalem, the home of the Albert Einstein Archives(档案馆). "We worked very closely with it to bring the product onto the market," the company's Dr Jeanne Lim said.
Einstein robot was introduced to the public at the Consumer Electronics Show in Las Vegas and was quickly hailed by those who saw it. "He became one of the breakout stars of the convention," wrote Melia Robinson on Business Insider. "Crowds flooded into the company to have a look at the little guy."
"Technology is often now very cold and socially isolated(孤立的)," explained David Hanson, the cofounder of the company behind the new robot. "By bringing a lively character into our physical world, we're humanizing(使人性化) the technology instead of dehumanizing the humans."
As for Hanson Robotics, the company has been building human-sized robots for over a decade. But this marks the company's first commercially available product. "Professor Einstein is just the start," said Hanson. "We're witnessing the arrival of conversational robots that can walk in our world. It's a golden age of invention."
1.What can Einstein robot do
A.Teach you to learn any new language. B.Have a regular conversation with you.
C.Design a number of science questions. D.Keep track of other robots constantly.
2.Which of the following best explains "hailed" underlined in Paragraph 4
A.Broken. B.Improved. C.Ignored. D.Praised.
3.What can be inferred from David Hanson's words
A.He expects humans to be less isolated from robots.
B.He dreams of humanizing humans through invention.
C.He worries about a golden age of conversational robots.
D.He stays hopeful about the future of robot invention.
4.What can be a suitable title for the text
A.A New Robot Makes Humans Much Happier B.The Golden Age of Invention Is Approaching
C.Albert Einstein "Changes" Into an Assistant D.Albert Einstein Helps to Humanize Robots

Music is an art form which deals with the representation of emotion through the medium of sound. It can have a physical effect on us because it is closely linked with emotion, perhaps even more than the abstract words. The first reason why people listen to music is to adjust their emotional slate. ①_____
Numerous studies show us that there's no doubt that music can affect our mood state and stress level. ②_____ For example, they have found that background music shuts out distractions. It calms them before a large task and then they can stay focused for longer. Also, it can help their creativity and make studying more enjoyable.
③_____ Firstly, it depends on what the task is. The more difficult the challenge is, the more likely background music will interrupt the learning process. For less challenging learning tasks, music can greatly assist in providing a positive learning state. Secondly, it depends on the characteristics of the music we'll come to in a moment. And thirdly, extroverts (性格外向者) enjoy and often require more external stimulation (刺激) and are likely to handle background noise better than those who are quiet and shy.
Actually, it's not the genre (类型) of music, but the natural musical characteristics that aid or disrupt study. One of these characteristics is the tempo (拍子). The recommended tempo for background music is in the range of 70 to 110 beats per minute, slightly faster than the heartbeat when we are at rest. ④_____ And very slow music lowers the heartbeat, creating a state that might be too relaxed for study purposes.
In addition, lyrics (歌词) are the most distracting aspect of listening to background music. ⑤_____ More particularly, studies have found that the most distracting background music is fast and familiar vocal music, chosen and liked by the listener.
A. Music is part of every culture in the world.
B. In a very real sense, music connects us with our inner selves.
C. Music, like language, is a unique human form of communication.
D. They compete with the same brain regions that process language.
E. Fast music raises the heartbeat, making one unable to focus on study.
F. There are a few factors that determine the effects of music on studying.
G. Moreover, those who like studying with background music have found a lot of benefits.

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。
Ten-year-old Sam loved to visit his grandfather's house. The house was near the beautiful blue sea. At the seaside stood thick and tall palm trees with coconuts hanging from them. When the coconuts fell down, Sam would break them open and drink the coconut juice. Sam liked to play under the trees. It was always great fun to spend the holidays at Grandpa's place.
This winter vacation, Sam was surprised when he came to his grandfather's village. There were hardly any trees left. He saw houses built near the sea. People had cut down many palm trees and there was hardly any greenery left.
Grandpa's house was different. He never allowed his trees to be cut. He hugged each palm tree in his courtyard. He also named the two big trees near the front door—one was Petu, and the other Betu. He had planted them with his own hands and today they had become large, massive trees with thick trunks. They were tall and green and gave the sweetest, juiciest coconuts.
One night, Sam was awakened by a strange sound. He could not sleep. He tossed and turned (辗转反侧) in bed. Suddenly, the ground began shaking as if the earth was splitting. He sat up straight and then ran to Grandpa. He clung (附着) to his grandpa. Grandpa cried out, "It's an earthquake! It's an earthquake!" They ran outside the house. They thought that it would be safer there.
Suddenly, there was a loud sound; the earth was not splitting but the sea was roaring. People were shouting, screaming and crying, "The sea is rising! The sea is rising!" The villagers started running away from the beach. Sam was dumbstruck (呆若木鸡).
The waves were rising higher and higher. Sam thought, "How big the waves are!" He went into the house again and saw water coming in from all sides. He was scared.
Sam remembered his mother telling him long ago, "You must always get out of the house if the floods come too near." So he ran out to be with Grandpa.
Waves about twelve meters high came rushing in, drowning everything. Water was all around and everywhere.

第二节
答案： Grandpa held Sam's hand tightly but a huge wave separated them. Grandpa fought the waves and strived to catch Sam, but failed. Sam was washed away! Grandpa struggled to keep his head above the water. The water pushed him ahead. Fortunately, he caught a palm tree in his courtyard. He panicked and screamed out at Sam but could not see him. He clung to the tree tightly while the water was all around. In the hope of seeing Sam, Grandpa climbed higher up the tree. The water carried Sam round and round.
"Sam! Sam!" cried Grandpa. "Don't be scared, little e to me, quickly!" "But Grandpa, I can't swim!" Another wave came with terrifying speed and force. Sam cried in despair. Suddenly, Sam felt himself thrown onto the top of a tree. He immediately held it! Looking around, he saw everything was terribly destroyed; but in the near distance, Grandpa was in another tree! Soon it was calm; both Grandpa and Sam came down from the trees and rushed to hug each other, and then they hugged the trees with tears of gratitude.
