She graduated from Peking University Medical School in 1955. In 1967, the Chinese government formed a team of scientists with the objective of discovering a new treatment for malaria, and Tu Youyou was among the first researchers chosen for this significant project. In 1969, Tu Youyou became the head of the project in Beijing. She decided to review ancient Chinese medical texts to find traditional botanical treatments for the disease. Her team examined over 2,000 old medical texts and evaluated 280,000 plants for their medical properties. After countless experiments and facing numerous failures, in 1971, her team finally succeeded in finding a substance that worked by using a lower temperature to draw out the extract. This medicine, which was called artemisinin, soon became a standard treatment for malaria. Artemisinin has saved hundreds of thousands of lives and has led to improved health for millions of people. Over 200 million people around the world get malaria each year, and about 600,000 die from it. Artemisinin has become a vital part of the treatment for malaria and is thought to save 100,000 lives a year in Africa alone. In 2015, Tu Youyou was awarded the Nobel Prize for Physiology or Medicine. This award not only recognized her individual efforts but also the collective work of her team.

In 1960, she traveled to Tanzania to study chimpanzees in the Gombe Stream National Park. This was an extremely challenging task as there was very little known about the behavior of chimpanzees in the wild at that time. Goodall didn't have a formal background in animal research when she started. However, her passion and determination drove her forward. She spent countless hours observing the chimpanzees, living among them in the jungle. She made some astonishing discoveries. For example, she found that chimpanzees use tools, which was a revolutionary finding as it was previously thought that only humans had the ability to use tools. They would modify twigs to fish for termites, showing a level of intelligence and adaptability that surprised the scientific community. Over the years, her research expanded. She studied the social lives of chimpanzees, observing their family structures, mating habits, and how they interacted with each other within the group. Her 45 - year - long study provided in - depth insights into the complex behaviors and emotions of these primates. Goodall's work not only advanced our understanding of chimpanzees but also had a profound impact on the field of animal behavior research in general. It inspired many other scientists to study animals in their natural habitats and changed the way we view the relationship between humans and other animals. 1.

It is a natural wonder that stretches over 2,300 kilometers and is made up of thousands of individual reefs and hundreds of islands. The reef is famous for its incredibly rich biodiversity. It is home to a vast array of marine life, including colorful fish, dolphins, whales, sea turtles, and countless species of coral. The coral, which comes in various shapes and colors, forms the backbone of the reef ecosystem. Divers and snorkelers from all over the world are attracted to the reef to experience its underwater beauty firsthand. They can swim among the fish, observe the coral up close, and witness the complex interactions of the marine creatures. However, the Great Barrier Reef is facing serious threats. Climate change is causing rising sea temperatures, which lead to coral bleaching. When the water gets too warm, the coral expels the algae living in its tissues, turning it white. This not only makes the coral more vulnerable to disease but also disrupts the entire reef ecosystem. Additionally, pollution from agricultural runoff and coastal development is also harming the reef. Chemicals and sediment in the runoff can smother the coral and reduce water quality, making it difficult for the marine life to survive. 1. Where is the Great Barrier Reef located? A.

For example, the “OK” gesture, which is formed by connecting the thumb and index finger to create a circle, has different interpretations around the world. In the United States and many European countries, it generally means “all is well” or “approval.” However, in Brazil and Germany, this gesture can be considered offensive, similar to using a vulgar word. Another common gesture is pointing with a finger. In English - speaking countries, pointing is often used to indicate a person, object, or direction. But in some Asian cultures, such as Japan and South Korea, pointing directly at someone with one finger is considered impolite. Instead, people may use an open hand or their chin to gesture. Eye contact is also a significant aspect of non - verbal communication. In Western cultures, maintaining eye contact during a conversation is seen as a sign of attentiveness and honesty. On the other hand, in some Asian cultures, too much eye contact, especially between people of different social statuses, may be considered disrespectful. For instance, a subordinate may avoid direct eye contact with a superior as a sign of deference. Understanding these cultural differences in gestures is crucial, especially in today's globalized world. When traveling or interacting with people from different cultures, being aware of these nuances can prevent misunderstandings and help build better relationships. 1. What does the “OK” gesture mean in Brazil? A. All is well. B. Approval. C. It is offensive. D. No meaning. 2. In which countries is pointing directly at someone with one finger considered impolite? A. The United States and England. B. Japan and South Korea. C. Brazil and Germany. D. France and Italy. 3. Why is it important to understand cultural differences in gestures? A. Because gestures are more important than verbal communication. B. Because it can help us make more friends. C. Because it can prevent misunderstandings and build better relationships. D. Because it shows our knowledge of different cultures. Facial expressions are often thought of as a universal language that can convey emotions across different cultures. Research has shown that certain basic emotions, such as happiness, sadness, anger, fear, surprise, and disgust, are associated with distinct facial expressions that are recognized by people around the world. For example, a smile is commonly understood as a sign of happiness in almost every culture. Similarly, a frown typically indicates sadness or displeasure. However, while the basic facial expressions for these emotions may be universal, the way they are expressed and interpreted can still vary in different cultural contexts. In some cultures, people may be more reserved and less likely to show strong emotions on their faces in public. In contrast, in other cultures, facial expressions may be more exaggerated and openly displayed. Moreover, the meaning of facial expressions can also be influenced by social situations. For instance, a smile may not always mean happiness. In some cultures, a smile can be used to mask embarrassment, nervousness, or even anger. Similarly, the expression of anger may be more or less acceptable depending on the context and the relationship between people. Overall, although facial expressions do have some universal aspects in conveying emotions, their interpretation is also shaped by cultural and social factors. Recognizing these differences can help us communicate more effectively with people from diverse backgrounds. 1. Which of the following is NOT a basic emotion associated with a distinct facial expression? A. Happiness. B. Love. C. Fear. D. Surprise. 2. Why may the interpretation of facial expressions vary in different cultures? A. Because people in different cultures have different languages. B. Because some cultures don't have facial expressions. C. Because the way they are expressed and interpreted can be affected by cultural and social factors. D. Because people in some cultures are not good at expressing emotions. 3. What can we conclude from the passage? A. Facial expressions are completely a universal language. B. We don't need to pay attention to cultural differences in facial expressions. C. Understanding the cultural and social factors influencing facial expressions helps with communication. D. A smile always means happiness in all cultures. 选择性必修一Unit 5 The organic food has gained a lot of popularity as it is being considered healthier and tastier. A fair number of people advocate a large - scale shift to organic farming from conventional agriculture. But this might not seem well - founded. Since the mid - 19th century, conventional industrial agriculture has become incredibly efficient on a simple land - to - food basis. Conventional farming gets more crops per square foot of land, which can mean less wilderness needs to be transformed to farmland. To make farming more efficient, conventional agriculture uses a significant amount of synthetic fertilizer each year, and all that nitrogen enables much faster plant growth. However, the cost is paid in vast polluted dead zones at the mouths of many of the world’s rivers, because much of the nitrogen ends up running off the soil and into the oceans. This also makes conventional farming one of the major threats to the environment. To weaken the environmental impact of agriculture, improve soil quality as well as produce healthier foods, some farmers have turned to organic farming. Environmentalists have also welcomed organic food as better for the planet than the food produced by agricultural corporations. Organic practices — refusing artificial fertilizers and chemical pesticides — are considered far more sustainable. Sales of organic food rose 7.7% in 2010, up to $26.7 billion — and people are making those purchases for their moral senses as much as for their taste buds. Yet a new meta - analysis （综合分析） of 71 studies shows that organic crops are, on average, 25% less productive than conventional ones. This productivity gap is a concern because we will need to produce 70% more food by 2050 to feed the world’s growing population. 1. Why has conventional industrial agriculture become efficient? A. It uses a large amount of natural fertilizer. B. It can get more crops per square foot of land. C. It is welcomed by most environmentalists. D. It transforms more wilderness into farmland. 2. What is one of the problems of conventional farming? A. It causes damage to the environment. B. It needs more labor force. C. It costs more than organic farming. D. It produces less food than organic farming. 3. What can we learn from the new meta - analysis? A. Organic food is healthier and tastier. B. Organic farming is more sustainable. C. Organic crops have a lower productivity. D. Organic farming should be promoted. Compassion and love are concepts that are often thought to be felt by humans only. As the most intelligent creatures to ever walk the earth, we tend to assume that we are the only ones who can feel emotions. We forget that the speechless beings who live here with us — animals — also have the same capability. During a cold night in Ontario, Canada, a passer - by spotted something on the side of the road that made her stop — a shaking dog curled up in the snow. When she approached the pup, she discovered that “she” wasn’t alone — “she” was cuddling five orphaned black kittens to keep them warm. The dog surely could have found a safer place to stay for the night, but she chose instead to help not just herself but other stray animals as well. The Good Samaritan called Pet and Wildlife Rescue and an animal control officer picked them up. When they got to the shelter, it was apparent that a close bond had already been formed between the dog and the orphaned kittens. The staff decided to name the kind dog Serenity in honor of her selfless act. “It’s truly heart - warming!” a shelter spokesperson told The Dodo. “It had been a very cold night so these kittens would have had a very hard time surviving.” Aside from requiring treatment for worm and flea infections, the orphaned kittens are now safe. Just like a proud and doting mother, Serenity insisted on checking on her babies regularly to oversee their progress. The good news is that the kittens are now living with a foster family who will care for them until they are old enough to be adopted. Serenity, on the other hand, is still looking for a family. According to the shelter, she loves zooming around in the yard and is big on playing. She is also quite jumpy, so she would do best in a home without small children. 1. What did the passer - by see on the road? A. A dog curled up in the snow. B. Five kittens were in the snow alone. C. A dog was warming five kittens. D. A dog was playing with five kittens. 2. What does the underlined word “pup” in Paragraph 2 refer to? A. The passer - by. B. The dog. C. One of the kittens. D. The animal control officer. 3. What can we infer from the story? A. Animals don’t feel emotions like humans. B. The dog will be adopted by the shelter staff. C. The kittens are still in the shelter waiting for adoption. D. Animals can feel compassion and love just like humans. 选择性必修二Unit 1 Born on July 1st, 1948, in the small Italian city of Palmi, Roberto Crea was a genius kid. He moved to the Netherlands and majored in biological chemistry. It was this university that directed his interest into the synthesis of nucleotides, the basic units that are required to build DNA. At that time, not many researchers studied the combination of genes, but Roberto’s strong chemistry background made a historical invention possible. In 1977, he joined Genentech, Inc. and the gene synthesis team at City of Hope Medical School. The company funded Dr. Crea’s ongoing research on gene synthesis. After working day and night, the brilliant individual finally invented a new procedure that improved the chemical synthesis of genes. Thanks to his rich knowledge and the joint effort of the excellent Genentech team, he made use of this invention to produce the human insulin genes, A and B. It was his invention that allowed Genentech to be labeled as the first producer of human protein. This benefited hundreds of millions of people suffering from diabetes all over the world. Today Roberto is known as the father of synthetic insulin and had almost won the Nobel Prize. His efforts did not stop after discovering the synthetic insulin; in fact, he was more than driven and tried to make more contributions to the field of biotechnology. His team of experts discovered ziconotide under his teachings and guidance. According to leading scientists and researchers, this drug is more powerful and effective than morphine, and the best part of this is that it has zero side - effects. Dr. Roberto Crea has a long list of creditable discoveries and researches that he has achieved in 76 years of his life. He is an inspiration for many individuals who aim to add value to humanity with the help of science. 1. What may contribute to Roberto’s invention of the human insulin genes? A.

If a president, a philosopher, and one of the best - selling writers credited the same secret with their success, would you try to follow it too? What if the secret was something you already knew how to do? In fact, you probably do it every day. Here’s what Friedrich Nietzsche wrote: “It is only ideas gained from walking that have any worth.” Thomas Jefferson: “Walking is the best possible exercise.” Charles Dickens: “If I could not walk far and fast, I think I should just explode and perish.” Researchers have found quite a lot of connections between walking and producing ideas. A Stanford University study found that participants were 81 percent more creative when walking as opposed to sitting. According to the study, walking outside, whether it is a quick stroll or a long hike, can increase the level of creativity. The researchers believe that the physical movement of walking, combined with the change of scenery and the fresh air, stimulates the brain and helps it make new connections. When you walk, your body is in motion, which increases blood flow to the brain. This provides more oxygen and nutrients to the brain cells, enabling them to function more efficiently. Moreover, the rhythm of walking can also have a calming effect on the mind, reducing stress and allowing for more free - flowing thinking. In addition to the physical and mental benefits, walking can also expose you to new stimuli. You might see different landscapes, meet new people, or notice details that you would have missed while sitting indoors. All these new experiences can spark new ideas and perspectives. So, the next time you are stuck in a creative rut or need to solve a difficult problem, consider going for a walk. It could be the key to unlocking your creativity and finding the solutions you need. 1. What is the main idea of the passage? A. The benefits of walking for physical health. B. The connection between walking and creativity. C. The different opinions of famous people on walking. D. The ways to increase creativity while walking. 2. What did the Stanford University study find? A. People are more creative when sitting than walking. B. Walking can increase creativity by 81 percent. C. Participants were more creative when walking than sitting. D. The longer people walk, the more creative they become. 3. Why can walking stimulate the brain? A. Because it makes people feel more relaxed. B. Because it provides more oxygen and nutrients to the brain cells. C. Because it exposes people to new stimuli. D. All of the above. 4. What does the underlined phrase “stuck in a creative rut” mean? A. Unable to come up with new ideas. B. Having a lot of creative ideas. C. Being in a difficult situation. D. Having a strong desire to create. 选择性必修二Unit 2 Historical heritage sites around the world are like precious time capsules, preserving the rich tapestry of human history, culture, and traditions. These sites range from ancient ruins of once - great civilizations to magnificent palaces and temples that have withstood the test of time. Take, for example, the Great Wall of China. Stretching across the northern part of the country, it is one of the most iconic historical landmarks globally. Built over several centuries, the Great Wall was originally constructed as a series of fortifications to protect against invasions. Its massive structure, snaking through mountains, deserts, and grasslands, not only showcases the extraordinary engineering skills of ancient Chinese but also reflects the social, political, and military aspects of that era. Tourists visiting the Great Wall are not only awed by its grandeur but also gain a deeper understanding of China's long - standing history and the perseverance of its people. Another remarkable heritage site is the Acropolis in Athens, Greece. Standing atop a rocky hill, the Acropolis is home to some of the most significant ancient Greek buildings, such as the Parthenon. These architectural masterpieces are renowned for their harmonious proportions, exquisite sculptures, and the advanced building techniques used over 2,000 years ago. The Acropolis is not just a collection of ruins; it is a symbol of ancient Greek civilization, representing its achievements in art, architecture, philosophy, and democracy. It has inspired countless generations of artists, architects, and thinkers, and continues to be a source of pride for the Greek people. However, historical heritage sites face numerous threats in the modern world. Urbanization, climate change, and human - made damage pose significant risks to their preservation. For instance, pollution and acid rain can corrode the materials of ancient buildings, while large - scale construction projects near heritage sites may disrupt their historical context.

In recent years, digital technology has emerged as a powerful tool in the preservation of cultural heritage. With the rapid development of technologies such as 3D scanning, virtual reality (VR), and augmented reality (AR), it has become possible to capture, preserve, and present cultural heritage in new and innovative ways. 3D scanning is one of the most widely used techniques. It can create highly detailed digital models of historical buildings, artifacts, and archaeological sites. For example, in Italy, 3D scanning has been used to document the Colosseum. The technology precisely captures every curve, crack, and texture of the ancient amphitheater, creating a digital twin that can be studied, explored, and shared without causing any damage to the original structure. This digital model can also be used for restoration purposes, helping experts understand the original appearance of the building and plan restoration work more accurately. Virtual reality and augmented reality technologies offer immersive experiences for people to engage with cultural heritage. VR allows users to enter a virtual environment and explore historical sites as if they were actually there. For instance, museums can create VR exhibits that transport visitors back in time to ancient civilizations, enabling them to walk through ancient streets, visit palaces, and interact with virtual characters. AR, on the other hand, overlays digital information onto the real world. In a historical site, visitors can use their mobile devices with AR apps to see how the site looked in the past, view additional historical information, or even watch virtual reconstructions of historical events taking place on the actual site. Digital technology also plays a crucial role in making cultural heritage more accessible to a global audience. Through online platforms, digital collections of cultural heritage can be shared with people around the world. This not only promotes cultural exchange but also helps raise awareness about the importance of cultural heritage preservation. However, while digital technology offers great opportunities, it also brings challenges.

Its origins can be traced back to ancient civilizations. In ancient Greece, people baked flatbreads with various toppings, which were a precursor to modern - day pizza. However, it was in Naples, Italy, that pizza as we know it today truly took shape. In the 18th and 19th centuries, Naples was a bustling city with a large working - class population. Pizza became a popular and affordable meal for the locals. These early pizzas were simple, with a basic dough topped with tomatoes, cheese, and sometimes herbs. They were often sold by street vendors and eaten on the go. The turning point for pizza’s popularity came in 1889 when a Neapolitan pizza maker named Raffaele Esposito created a special pizza for the visit of King Umberto I and Queen Margherita of Italy. To represent the colors of the Italian flag, he used tomatoes (red), mozzarella cheese (white), and basil (green). This pizza, named Pizza Margherita, not only became an instant favorite of the royal couple but also a symbol of Italian national identity. As Italians immigrated to other parts of the world, especially the United States, they brought their love for pizza with them. In the early 20th century, the first pizzerias opened in American cities like New York. Initially, pizza was mainly popular among Italian - American communities. But over time, with marketing efforts and the increasing acceptance of diverse cuisines, pizza became a mainstream food in America. Today, pizza is a global phenomenon, with countless variations in toppings, crust styles, and cooking methods. From the thin - crust New York - style pizza to the deep - dish Chicago - style pizza, each region has put its own spin on this classic dish. 1. What was the precursor of modern - day pizza? A. Ancient Greek flatbreads with toppings. B. Neapolitan street - sold bread. C. The bread baked by Raffaele Esposito. D. The food sold in early American pizzerias. 2.

The story began on 8 July, 2017. Members of the Ursrey family, eight in total, were enjoying an evening together at the beach. As the sun sank lower on the horizon, the two boys - Noah, 11 and Stephen, 8 - took their skateboards and walked into the waves without the grown - ups noticing. When the boys were about 70 yards from shore, they realised that the ocean pulled them out to sea. After trying and failing to paddle back, they started waving and screaming for help. But the lifeguards had clocked out for the evening. The boys had been struggling for several minutes when Brittany and Tabatha Monroe, a married couple from Georgia, wandered by. They didn't see the boys at first, but they heard them. They jumped into the water and easily reached the brothers, who were still in fairly shallow water. The woman reassured the frightened boys and seized their skateboards, telling them they would be safe and then discovered that they, too, were now in a world of trouble. They couldn't get back to shore and could barely and only occasionally hit the sandy bottom with their feet. After a few minutes, it was clear to the woman that they were all trapped in a terrible whirlpool. Then scores of tourists were walking to them, hand in hand, forming a line. Soon the first person held the woman's hand. In turn, her husband and the two boys joined her. The long line moved slowly until they were back to the safety of the beach. The rescuers call it the Human Chain. But it was the deeply “human” aspect of the rescuers' cooperation that made it so astonishing and successful. 1. What happened to the two boys? A. They were playing skateboards on the beach. B. They were washed away by the waves while swimming. C. They were carried out to sea by the ocean current. D.

Which of the following best describes the water the young couple stayed in? A. It was calm. B. It was shallow. C. It was in a whirlpool. D. It was deep. 4. What made the four people in the sea escape the risky situation? A. The lifeguards' timely rescue. B. The boys' strong will to survive. C. The couple's great swimming skills. D. The tourists' cooperation in forming a human chain. It was a cold March day in High Point, North Carolina. The girls on the Wesleyan Academy softball team were waiting for their next turns at bat during practice, stamping their feet to stay warm. Eighth - grader Taylor Bisbee shivered a little as she watched her teammate Paris White play. The two didn't know each other well—Taylor had just moved to town a month or so before. Suddenly, Paris fell to the ground. “Paris's eyes rolled back,” Taylor says. “She started shaking. I knew it was an emergency.” It certainly was. Paris had suffered a sudden heart failure. Without immediate medical care, Paris would die. At first, no one moved. The girls were in shock. Then the softball coach shouted out, “Does anyone know CPR?” CPR is a life - saving technique. To do CPR, you press on the sick person's chest so that blood moves through the body and takes oxygen to organs. Without oxygen, the brain is damaged quickly. Amazingly, Taylor had just taken a CPR course the day before. Still, she hesitated. She didn't think she knew it well enough. But when no one else came forward, Taylor ran to Paris and began doing CPR. “It was scary. I knew it was the difference between life and death,” says Taylor. Taylor's swift action helped her teammates calm down. One girl called 911. Two more ran to get the school nurse, who brought a defibrillator, an electronic device that can shock the heart back into work. Luck stayed with them: Paris's heartbeat returned. “I know I was really lucky,” Paris says now. “Most people don't survive this. My team saved my life.” Experts say Paris is right: For a sudden heart failure, the single best chance for survival is having someone nearby step in and do CPR quickly. Today, Paris is back on the softball team. Taylor will apply to college soon. She wants to be a nurse. “I feel more confident in my actions now,” Taylor says. “I know I can act under pressure in a scary situation.” 1. What happened to Paris on a March day? A. She caught a bad cold. B. She had a sudden heart problem. C. She was knocked down by a ball. 2. Why did Paris say she was lucky? A. She made a lot of friends. B. She recovered from shock. C. She received immediate CPR. 3. Which of the following words can best describe Taylor? A. Brave and calm. B. Patient and curious. C. Honest and creative. 7 / 10 学科网（北京）股份有限公司 $$ 限时练习：40min 完成时间： 月 日 天气： 第10练 阅读理解20篇 选择性必修一Unit 1 Tu Youyou, a committed and patient scientist, was born in Ningbo, China, on 30 December 1930.

For example, the “OK” gesture, which is formed by connecting the thumb and index finger to create a circle, has different interpretations around the world. In the United States and many European countries, it generally means “all is well” or “approval.” However, in Brazil and Germany, this gesture can be considered offensive, similar to using a vulgar word. Another common gesture is pointing with a finger. In English - speaking countries, pointing is often used to indicate a person, object, or direction. But in some Asian cultures, such as Japan and South Korea, pointing directly at someone with one finger is considered impolite. Instead, people may use an open hand or their chin to gesture. Eye contact is also a significant aspect of non - verbal communication. In Western cultures, maintaining eye contact during a conversation is seen as a sign of attentiveness and honesty. On the other hand, in some Asian cultures, too much eye contact, especially between people of different social statuses, may be considered disrespectful. For instance, a subordinate may avoid direct eye contact with a superior as a sign of deference. Understanding these cultural differences in gestures is crucial, especially in today's globalized world. When traveling or interacting with people from different cultures, being aware of these nuances can prevent misunderstandings and help build better relationships. 1. What does the “OK” gesture mean in Brazil? A. All is well. B. Approval. C. It is offensive. D. No meaning. 答案：C 解析：根据文中“However, in Brazil and Germany, this gesture can be considered offensive, similar to using a vulgar word.”可知，在巴西，“OK”手势是具有冒犯性的，所以答案选C。 2.

Research has shown that certain basic emotions, such as happiness, sadness, anger, fear, surprise, and disgust, are associated with distinct facial expressions that are recognized by people around the world. For example, a smile is commonly understood as a sign of happiness in almost every culture. Similarly, a frown typically indicates sadness or displeasure. However, while the basic facial expressions for these emotions may be universal, the way they are expressed and interpreted can still vary in different cultural contexts. In some cultures, people may be more reserved and less likely to show strong emotions on their faces in public. In contrast, in other cultures, facial expressions may be more exaggerated and openly displayed. Moreover, the meaning of facial expressions can also be influenced by social situations. For instance, a smile may not always mean happiness. In some cultures, a smile can be used to mask embarrassment, nervousness, or even anger. Similarly, the expression of anger may be more or less acceptable depending on the context and the relationship between people. Overall, although facial expressions do have some universal aspects in conveying emotions, their interpretation is also shaped by cultural and social factors. Recognizing these differences can help us communicate more effectively with people from diverse backgrounds. 1. Which of the following is NOT a basic emotion associated with a distinct facial expression? A. Happiness. B. Love. C. Fear. D.

What can we conclude from the passage? A. Facial expressions are completely a universal language. B. We don't need to pay attention to cultural differences in facial expressions. C. Understanding the cultural and social factors influencing facial expressions helps with communication. D. A smile always means happiness in all cultures. 答案：C 解析：由文章最后一句“Recognizing these differences can help us communicate more effectively with people from diverse backgrounds.”可知，理解影响面部表情的文化和社会因素有助于交流，A选项面部表情完全是通用语言过于绝对；B选项我们不需要关注面部表情的文化差异错误；D选项微笑在所有文化中都意味着快乐也不正确，所以答案是C。 选择性必修一Unit 5 The organic food has gained a lot of popularity as it is being considered healthier and tastier. A fair number of people advocate a large - scale shift to organic farming from conventional agriculture. But this might not seem well - founded. Since the mid - 19th century, conventional industrial agriculture has become incredibly efficient on a simple land - to - food basis. Conventional farming gets more crops per square foot of land, which can mean less wilderness needs to be transformed to farmland. To make farming more efficient, conventional agriculture uses a significant amount of synthetic fertilizer each year, and all that nitrogen enables much faster plant growth. However, the cost is paid in vast polluted dead zones at the mouths of many of the world’s rivers, because much of the nitrogen ends up running off the soil and into the oceans. This also makes conventional farming one of the major threats to the environment. To weaken the environmental impact of agriculture, improve soil quality as well as produce healthier foods, some farmers have turned to organic farming. Environmentalists have also welcomed organic food as better for the planet than the food produced by agricultural corporations. Organic practices — refusing artificial fertilizers and chemical pesticides — are considered far more sustainable. Sales of organic food rose 7.7% in 2010, up to $26.7 billion — and people are making those purchases for their moral senses as much as for their taste buds. Yet a new meta - analysis （综合分析） of 71 studies shows that organic crops are, on average, 25% less productive than conventional ones. This productivity gap is a concern because we will need to produce 70% more food by 2050 to feed the world’s growing population. 1. Why has conventional industrial agriculture become efficient? A. It uses a large amount of natural fertilizer. B. It can get more crops per square foot of land. C. It is welcomed by most environmentalists. D. It transforms more wilderness into farmland. 答案：B 解析：根据文章第二段“Conventional farming gets more crops per square foot of land, which can mean less wilderness needs to be transformed to farmland.”可知，传统农业高效是因为每平方英尺土地能产出更多作物，所以答案选B。A选项错在使用的是合成肥料而非天然肥料；C选项传统农业不受环保主义者欢迎；D选项是产出多的结果，不是高效的原因。 2. What is one of the problems of conventional farming? A. It causes damage to the environment. B. It needs more labor force. C. It costs more than organic farming. D. It produces less food than organic farming. 答案：A 解析：从文中“However, the cost is paid in vast polluted dead zones at the mouths of many of the world’s rivers... This also makes conventional farming one of the major threats to the environment.”可知，传统农业的问题之一是对环境造成破坏，所以选A。B选项文章未提及需要更多劳动力；C选项未比较成本；D选项传统农业产量比有机农业高。 3. What can we learn from the new meta - analysis? A. Organic food is healthier and tastier. B. Organic farming is more sustainable. C. Organic crops have a lower productivity. D. Organic farming should be promoted. 答案：C 解析：依据“Yet a new meta - analysis of 71 studies shows that organic crops are, on average, 25% less productive than conventional ones.”可知，新的综合分析表明有机作物产量更低，所以答案是C。A、B选项虽表述正确，但不是新综合分析得出的结论；D选项文章未提及应推广有机农业。 Compassion and love are concepts that are often thought to be felt by humans only. As the most intelligent creatures to ever walk the earth, we tend to assume that we are the only ones who can feel emotions. We forget that the speechless beings who live here with us — animals — also have the same capability. During a cold night in Ontario, Canada, a passer - by spotted something on the side of the road that made her stop — a shaking dog curled up in the snow. When she approached the pup, she discovered that “she” wasn’t alone — “she” was cuddling five orphaned black kittens to keep them warm. The dog surely could have found a safer place to stay for the night, but she chose instead to help not just herself but other stray animals as well. The Good Samaritan called Pet and Wildlife Rescue and an animal control officer picked them up. When they got to the shelter, it was apparent that a close bond had already been formed between the dog and the orphaned kittens. The staff decided to name the kind dog Serenity in honor of her selfless act. “It’s truly heart - warming!” a shelter spokesperson told The Dodo. “It had been a very cold night so these kittens would have had a very hard time surviving.” Aside from requiring treatment for worm and flea infections, the orphaned kittens are now safe. Just like a proud and doting mother, Serenity insisted on checking on her babies regularly to oversee their progress. The good news is that the kittens are now living with a foster family who will care for them until they are old enough to be adopted. Serenity, on the other hand, is still looking for a family. According to the shelter, she loves zooming around in the yard and is big on playing. She is also quite jumpy, so she would do best in a home without small children. 1. What did the passer - by see on the road? A. A dog curled up in the snow. B. Five kittens were in the snow alone. C. A dog was warming five kittens. D. A dog was playing with five kittens. 答案：C 解析：根据文章第二段“When she approached the pup, she discovered that “she” wasn’t alone — “she” was cuddling five orphaned black kittens to keep them warm.”可知，路人看到一只狗在给五只小猫取暖，所以答案是C。A选项不完整；B选项小猫不是独自在雪中；D选项不是在玩耍。 2. What does the underlined word “pup” in Paragraph 2 refer to? A. The passer - by. B. The dog. C. One of the kittens. D. The animal control officer. 答案：B 解析：前文提到“A passer - by spotted something on the side of the road... a shaking dog curled up in the snow.”，后文又说“she discovered that “she” wasn’t alone”，这里的she指的是前文的狗，所以pup指的是狗，答案选B。 3. What can we infer from the story? A. Animals don’t feel emotions like humans. B. The dog will be adopted by the shelter staff. C. The kittens are still in the shelter waiting for adoption. D. Animals can feel compassion and love just like humans. 答案：D 解析：文章第一段提到人类常认为只有自己能感受情感，却忽略了动物也有同样能力，接着讲述了狗照顾小猫的故事，所以可以推断出动物能像人类一样感受同情和爱，答案是D。A选项与文章观点相反；B选项文章未提及狗会被收容所工作人员收养；C选项小猫已被寄养家庭收养。 选择性必修二Unit 1 Born on July 1st, 1948, in the small Italian city of Palmi, Roberto Crea was a genius kid. He moved to the Netherlands and majored in biological chemistry. It was this university that directed his interest into the synthesis of nucleotides, the basic units that are required to build DNA. At that time, not many researchers studied the combination of genes, but Roberto’s strong chemistry background made a historical invention possible. In 1977, he joined Genentech, Inc. and the gene synthesis team at City of Hope Medical School. The company funded Dr. Crea’s ongoing research on gene synthesis. After working day and night, the brilliant individual finally invented a new procedure that improved the chemical synthesis of genes. Thanks to his rich knowledge and the joint effort of the excellent Genentech team, he made use of this invention to produce the human insulin genes, A and B.

What if the secret was something you already knew how to do? In fact, you probably do it every day. Here’s what Friedrich Nietzsche wrote: “It is only ideas gained from walking that have any worth.” Thomas Jefferson: “Walking is the best possible exercise.” Charles Dickens: “If I could not walk far and fast, I think I should just explode and perish.” Researchers have found quite a lot of connections between walking and producing ideas. A Stanford University study found that participants were 81 percent more creative when walking as opposed to sitting. According to the study, walking outside, whether it is a quick stroll or a long hike, can increase the level of creativity. The researchers believe that the physical movement of walking, combined with the change of scenery and the fresh air, stimulates the brain and helps it make new connections. When you walk, your body is in motion, which increases blood flow to the brain. This provides more oxygen and nutrients to the brain cells, enabling them to function more efficiently. Moreover, the rhythm of walking can also have a calming effect on the mind, reducing stress and allowing for more free - flowing thinking. In addition to the physical and mental benefits, walking can also expose you to new stimuli. You might see different landscapes, meet new people, or notice details that you would have missed while sitting indoors. All these new experiences can spark new ideas and perspectives. So, the next time you are stuck in a creative rut or need to solve a difficult problem, consider going for a walk. It could be the key to unlocking your creativity and finding the solutions you need. 1. What is the main idea of the passage? A. The benefits of walking for physical health. B.

With the rapid development of technologies such as 3D scanning, virtual reality (VR), and augmented reality (AR), it has become possible to capture, preserve, and present cultural heritage in new and innovative ways. 3D scanning is one of the most widely used techniques. It can create highly detailed digital models of historical buildings, artifacts, and archaeological sites. For example, in Italy, 3D scanning has been used to document the Colosseum. The technology precisely captures every curve, crack, and texture of the ancient amphitheater, creating a digital twin that can be studied, explored, and shared without causing any damage to the original structure. This digital model can also be used for restoration purposes, helping experts understand the original appearance of the building and plan restoration work more accurately. Virtual reality and augmented reality technologies offer immersive experiences for people to engage with cultural heritage. VR allows users to enter a virtual environment and explore historical sites as if they were actually there. For instance, museums can create VR exhibits that transport visitors back in time to ancient civilizations, enabling them to walk through ancient streets, visit palaces, and interact with virtual characters. AR, on the other hand, overlays digital information onto the real world. In a historical site, visitors can use their mobile devices with AR apps to see how the site looked in the past, view additional historical information, or even watch virtual reconstructions of historical events taking place on the actual site. Digital technology also plays a crucial role in making cultural heritage more accessible to a global audience. Through online platforms, digital collections of cultural heritage can be shared with people around the world. This not only promotes cultural exchange but also helps raise awareness about the importance of cultural heritage preservation. However, while digital technology offers great opportunities, it also brings challenges. Issues such as data security, digital ownership, and the long - term preservation of digital data need to be addressed to ensure the sustainable use of digital technology in cultural heritage preservation. 1.

Its origins can be traced back to ancient civilizations. In ancient Greece, people baked flatbreads with various toppings, which were a precursor to modern - day pizza. However, it was in Naples, Italy, that pizza as we know it today truly took shape. In the 18th and 19th centuries, Naples was a bustling city with a large working - class population. Pizza became a popular and affordable meal for the locals. These early pizzas were simple, with a basic dough topped with tomatoes, cheese, and sometimes herbs. They were often sold by street vendors and eaten on the go. The turning point for pizza’s popularity came in 1889 when a Neapolitan pizza maker named Raffaele Esposito created a special pizza for the visit of King Umberto I and Queen Margherita of Italy. To represent the colors of the Italian flag, he used tomatoes (red), mozzarella cheese (white), and basil (green). This pizza, named Pizza Margherita, not only became an instant favorite of the royal couple but also a symbol of Italian national identity. As Italians immigrated to other parts of the world, especially the United States, they brought their love for pizza with them. In the early 20th century, the first pizzerias opened in American cities like New York. Initially, pizza was mainly popular among Italian - American communities. But over time, with marketing efforts and the increasing acceptance of diverse cuisines, pizza became a mainstream food in America. Today, pizza is a global phenomenon, with countless variations in toppings, crust styles, and cooking methods. From the thin - crust New York - style pizza to the deep - dish Chicago - style pizza, each region has put its own spin on this classic dish. 1. What was the precursor of modern - day pizza? A.

It reflects the history, traditions, values, and social structures of a society. For example, in many Asian cultures, rice is a staple food that has been cultivated for thousands of years. The way rice is grown, prepared, and served is an integral part of the culture. In Japan, the art of making sushi, which uses rice as a base, is highly regarded. Sushi - making involves precise techniques and an understanding of the quality of ingredients. It is not only a culinary skill but also a cultural expression that reflects the Japanese values of precision, harmony, and respect for nature. In Western cultures, bread holds a significant place. In France, the baguette is more than just a type of bread; it is a symbol of French culture. The process of making a baguette requires patience and skill, from kneading the dough to baking it to a perfect golden - brown crust. French people often enjoy baguettes with cheese, butter, or cold cuts, and it is a common sight to see them walking down the street with a freshly baked baguette under their arm. This simple yet iconic food represents the French love for good food, their appreciation for the artisanal, and their relaxed lifestyle. Food also plays a crucial role in cultural celebrations. In the United States, Thanksgiving is a major holiday centered around a large meal. The traditional Thanksgiving dinner includes turkey, mashed potatoes, cranberry sauce, and pumpkin pie.

Platforms like Instagram, TikTok, and Snapchat have millions of young users worldwide. While social media offers various benefits, it also brings about significant impacts on teenagers' mental and social well - being. One of the positive aspects is that social media allows teenagers to connect with friends and family who are far away. They can share photos, videos, and experiences, strengthening their relationships. It also provides a platform for self - expression. Teenagers can showcase their talents, hobbies, and unique personalities through posts and stories, which may boost their self - confidence. Moreover, social media can be an educational tool. There are countless educational accounts that offer learning resources, from language lessons to science experiments, helping teenagers expand their knowledge. However, the negative impacts cannot be ignored. Excessive use of social media can lead to mental health problems. Constant exposure to carefully curated highlight reels of others' lives can make teenagers feel inadequate and envious. Cyberbullying is another serious issue. Hidden behind the screen, some users engage in hurtful behavior, sending mean messages or spreading rumors, which can cause severe emotional distress to the victims. Additionally, social media can be addictive. Many teenagers find themselves spending hours scrolling through feeds, which reduces the time they spend on physical activities, face - to - face social interactions, and studying. Parents, teachers, and society as a whole need to be aware of these impacts. Setting limits on social media use, teaching teenagers how to protect themselves online, and promoting real - world social skills are crucial steps in ensuring that teenagers can make the most of social media while minimizing its negative effects. 1.

AI - powered tools and technologies are being increasingly integrated into educational settings, bringing about both opportunities and challenges. One of the significant benefits of AI in education is personalized learning. AI algorithms can analyze students' learning patterns, strengths, and weaknesses based on their performance data, such as test scores, assignment completion, and engagement in class. With this information, educational platforms can offer customized learning materials and paths, ensuring that each student receives instruction tailored to their individual needs. For example, a student who struggles with math concepts can be provided with additional practice exercises and detailed explanations, while a more advanced student can be offered challenging enrichment activities. AI also has the potential to enhance teaching efficiency. Intelligent tutoring systems can answer students' questions in real - time, providing immediate feedback and support. This reduces the workload on teachers, allowing them to focus more on higher - level tasks, such as curriculum design and one - on - one student interaction. Additionally, AI - based assessment tools can quickly grade assignments and tests, providing teachers with timely data on students' progress. However, there are concerns associated with AI in education. One of the main issues is the potential for bias in AI algorithms. If the data used to train the algorithms is incomplete or contains biases, the resulting educational recommendations may be unfair or inaccurate. Another concern is the over - reliance on technology. If students become too dependent on AI - powered tools, they may lose important skills such as critical thinking and problem - solving. To fully realize the potential of AI in education, it is essential to address these challenges. Educators, researchers, and policymakers need to work together to ensure that AI is developed and used in an ethical and effective manner, striking a balance between leveraging technology and maintaining the human touch in education. 1. How does AI enable personalized learning? A. By providing the same learning materials to all students. B. By analyzing students' performance data to offer customized instruction. C. By replacing teachers completely in the classroom. D. By only focusing on students' strengths. 答案：B 解析：根据“AI algorithms can analyze students' learning patterns, strengths, and weaknesses based on their performance data... educational platforms can offer customized learning materials and paths”可知，人工智能通过分析学生的表现数据，为学生提供定制化的学习内容和路径，实现个性化学习，A选项提供相同学习材料不符合；C选项“完全取代教师”错误；D选项“只关注学生优势”表述片面，所以答案选B。 2. What is the advantage of AI - based assessment tools for teachers? A. They can make teachers' work more difficult. B. They can provide students with entertainment. C. They can quickly grade assignments and tests, offering timely data on students' progress. D. They can replace students' thinking and problem - solving. 答案：C 解析：文中提到“AI - based assessment tools can quickly grade assignments and tests, providing teachers with timely data on students' progress.”，说明基于人工智能的评估工具能快速批改作业和考试，为教师提供学生学习进展的及时数据，A选项使教师工作更困难错误；B选项为学生提供娱乐与评估工具的作用无关；D选项取代学生的思维和解决问题能力错误，所以选C。 3. What are the concerns about AI in education? A. AI algorithms are always accurate and unbiased. B. Students may become over - reliant on technology and lose important skills. C. AI cannot assist teachers in curriculum design. D. AI - powered tools are too expensive for schools to afford. 答案：B 解析：从“Another concern is the over - reliance on technology.

AI will completely take over the education industry. 答案：C 解析：文章开篇指出人工智能正在改变教育，接着阐述了其在教育中的好处，如个性化学习、提高教学效率等，同时也提到了存在的问题，如算法偏见、学生过度依赖等，所以文章主旨是人工智能在为教育带来机遇的同时也带来了挑战，C正确。A选项“无影响”错误；B选项“只带来好处”不全面；D选项“完全接管教育行业”过于绝对，所以选C。 选择性必修二Unit 5 Even now, almost a year after their astonishing act of group heroism, the dozens of people who risked their lives to save two boys from drowning in Panama City Beach are still remembered. The story began on 8 July, 2017. Members of the Ursrey family, eight in total, were enjoying an evening together at the beach. As the sun sank lower on the horizon, the two boys - Noah, 11 and Stephen, 8 - took their skateboards and walked into the waves without the grown - ups noticing. When the boys were about 70 yards from shore, they realised that the ocean pulled them out to sea. After trying and failing to paddle back, they started waving and screaming for help. But the lifeguards had clocked out for the evening. The boys had been struggling for several minutes when Brittany and Tabatha Monroe, a married couple from Georgia, wandered by. They didn't see the boys at first, but they heard them. They jumped into the water and easily reached the brothers, who were still in fairly shallow water. The woman reassured the frightened boys and seized their skateboards, telling them they would be safe and then discovered that they, too, were now in a world of trouble. They couldn't get back to shore and could barely and only occasionally hit the sandy bottom with their feet. After a few minutes, it was clear to the woman that they were all trapped in a terrible whirlpool. Then scores of tourists were walking to them, hand in hand, forming a line. Soon the first person held the woman's hand. In turn, her husband and the two boys joined her. The long line moved slowly until they were back to the safety of the beach. The rescuers call it the Human Chain. But it was the deeply “human” aspect of the rescuers' cooperation that made it so astonishing and successful. 1. What happened to the two boys? A. They were playing skateboards on the beach. B. They were washed away by the waves while swimming. C. They were carried out to sea by the ocean current. D.

The girls on the Wesleyan Academy softball team were waiting for their next turns at bat during practice, stamping their feet to stay warm. Eighth - grader Taylor Bisbee shivered a little as she watched her teammate Paris White play. The two didn't know each other well—Taylor had just moved to town a month or so before. Suddenly, Paris fell to the ground. “Paris's eyes rolled back,” Taylor says. “She started shaking. I knew it was an emergency.” It certainly was. Paris had suffered a sudden heart failure. Without immediate medical care, Paris would die. At first, no one moved. The girls were in shock. Then the softball coach shouted out, “Does anyone know CPR?” CPR is a life - saving technique. To do CPR, you press on the sick person's chest so that blood moves through the body and takes oxygen to organs. Without oxygen, the brain is damaged quickly. Amazingly, Taylor had just taken a CPR course the day before. Still, she hesitated. She didn't think she knew it well enough. But when no one else came forward, Taylor ran to Paris and began doing CPR. “It was scary. I knew it was the difference between life and death,” says Taylor. Taylor's swift action helped her teammates calm down. One girl called 911. Two more ran to get the school nurse, who brought a defibrillator, an electronic device that can shock the heart back into work. Luck stayed with them: Paris's heartbeat returned. “I know I was really lucky,” Paris says now. “Most people don't survive this. My team saved my life.” Experts say Paris is right: For a sudden heart failure, the single best chance for survival is having someone nearby step in and do CPR quickly. Today, Paris is back on the softball team. Taylor will apply to college soon. She wants to be a nurse. “I feel more confident in my actions now,” Taylor says. “I know I can act under pressure in a scary situation.” 1. What happened to Paris on a March day? A. She caught a bad cold. B. She had a sudden heart problem. C. She was knocked down by a ball. 答案：B 解析：根据“Paris had suffered a sudden heart failure.”可知，Paris突发心脏问题，B选项正确。A选项感冒文中未提及；C选项被球撞倒不符合原文，所以选B。 2. Why did Paris say she was lucky? A. She made a lot of friends. B. She recovered from shock. C. She received immediate CPR. 答案：C 解析：从“Most people don't survive this. My team saved my life.”以及“For a sudden heart failure, the single best chance for survival is having someone nearby step in and do CPR quickly.”可知，Paris说自己幸运是因为得到了及时的心肺复苏救助，C选项正确。A选项交到很多朋友与她觉得自己幸运无关；B选项从震惊中恢复不是关键原因，所以答案是C。 3. Which of the following words can best describe Taylor? A. Brave and calm. B. Patient and curious. C. Honest and creative. 答案：A 解析：Taylor在看到Paris突发状况时，虽然刚学CPR且有些犹豫，但最终还是勇敢地去实施救助，并且她的行动让队友冷静下来，说明她勇敢且冷静，A选项正确。B选项耐心和好奇、C选项诚实和有创造力在文中均未体现，所以选A。 7 / 10 学科网（北京）股份有限公司 $$
