TRANSCRIPTUse Habit Stacking to Help Get HealthyA woman in Portland, Oregon started her daily exercise habit with one activity — walking her dog. Lindsay Kee then added movements to this daily activity. (Q1) Before leaving on the walk, she did some standing stretches. On her return, she did other exercises such as jumping jacks.jumping jacks 开合跳Over time, Kee added more exercises around the dog walk. She said adding exercises to an existing activity took the pressure off of creating a whole new daily exercise. And now more than a year later, she consistently exercises around the dog walk.Kee said, “I’ve found it to be really effective in helping me be consistent with things that I really want to do.”What Kee did is called habit stacking. Writer S.J. Scott created this term for his 2014 book of the same name. (Q2) The idea behind habit stacking is to attach something you want to start doing to something you already do every day.habit stacking 习惯叠加A common example is flossing your teeth after brushing them. However, you can use habit stacking in many areas of your daily life. Kee, for example, places her vitamins next to the coffee machine. This helps her remember to take them every morning.Exercise experts say habit stacking is especially helpful if you are trying to increase exercise time.Dana Santas is a movement expert who has trained more than 50 professional sports teams. She combines exercise habits with personal health care. (Q3) For example, Santas does push-ups before every shower. And she does leg exercises while brushing her teeth. She says that her electric toothbrush makes a sound every 30 seconds to remind her to brush different teeth. But she uses the reminder to change her exercises. “It’s perfect,” she added.push-up n. 俯卧撑Two minutes of exercise may not get you in shape. But experts say, every little bit helps. (Q4) Experts at the U.S. Centers for Disease Control and Prevention suggest getting 150 minutes of moderate activity, like a fast walk, every week. Or you could also get 75 minutes of very energetic activity, like jogging, every week. The health experts also suggest two days a week of strength training.moderate adj. 适度的，中等强度的Most people find keeping new habits difficult. And while habit stacking is not a perfect solution, it does help with one barrier — decision-making.Gretchen Rubin is the writer of Better Than Before: Mastering the Habits of Our Everyday Lives. She said habit stacking is one of the best ways to start and keep new habits. The technique helps to remove the barrier of deciding when or if to do something.Rubin shared a story of her college days. To help her stay active, she would only shower if she had exercised that day.She suggested combining the new, or what she calls “shaky” behavior with something you have to do or deeply want to do.(Q5) “So you have to do the shaky habit before you get to the strong habit,” Rubin said. (Q5) If she wants to listen to a podcast, her strong habit, she must do it while exercising on a running machine. For her, this will strengthen her shaky habit.Part III. KEYQ1.

TRANSCRIPTWhat Is the healthiest way to prepare vegetables?Carlene Thomas is a dietitian, a person who gives advice about healthy foods to eat. When it comes to eating healthy vegetables, Thomas says there are two kinds of people who ask her for advice.dietitian n. 营养学家The first kind wants to know how different cooking methods affect the nutrition in vegetables. The other kind of person wants to know how to eat more vegetables. (Q1) Thomas’ simple answer to both groups is this: The best vegetables are the ones you actually want to eat.Thomas told the Associated Press that many people buy vegetables that they think they will eat. Maybe the produce is popular or someone is bringing attention to it on social media. But then they end up not using it. That means the vegetable gets thrown away after it goes bad.In that case, Thomas said, “It doesn’t matter how you cook them, because if they’re going in the trash, they’re not in your body.”(Q5) However, Thomas said research shows cooking methods do affect nutrition. But it is not as simple as comparing raw, or uncooked, vegetables to cooked ones. Cooking methods can include steaming, roasting, boiling, or sauteing.saute v. 煎，炒So, are raw vegetables healthier than cooked? Not always.When vegetables are cooked with high heat for a long period of time many nutrients break down. However, cooking softens the cell walls in vegetables, making them easier for the body to digest. (Q2) Cooking changes the structure of vegetables which increases what dietitians call bioavailability. This is the body’s ability to use the nutrients in vegetables, Thomas said.bioavailability n. 生物利用度（指身体吸收和利用营养的能力）Cooked food is often more nutritious than raw food. For example, cooked tomatoes release more of the antioxidant lycopene than raw tomatoes, she said. Lycopene is believed to have qualities that prevent cancer.nutritious adj. 有营养的，营养丰富的 antioxidant n. 抗氧化剂lycopene n. 番茄红素Also, cooked carrots have more beta-carotene that can be absorbed by the body. Roasting pumpkins, carrots and sweet potatoes increases available carotenoids. These antioxidants are thought to prevent inflammation in the body.pumpkin n. 南瓜carotenoid n. 类胡萝卜素inflammation n. 炎症Which cooking methods are the healthiest?However, the shorter the cooking time, the more nutrients are kept in the food. That advice comes from Amber Pankonin, a dietitian in the U.S. state of Nebraska.Cooking over boiling water, or steaming, and in a microwave are considered the most nutritious methods. These two methods use little time and require no fat.Another healthy method is blanching. This is when you boil vegetables in water for a minute or two. But not too long. (Q3) Boiling vegetables runs the risk of losing water-soluble nutrients including vitamin C, B1 and folate. Thomas explained the reason boiling is not good for vegetables: The nutrients are “leaching into the water, and you’re tossing out the water.”blanch v. 焯水，焯烫folate n. 叶酸leach v. （液体）过滤，浸出However, you could save the water from boiled vegetables and use it for other purposes, such as soups, or just drink it.What about taste?Dietitians say there is no problem using a small amount of fat. (Q4) Besides making vegetables taste better, a little cooking oil helps the body to absorb fat-soluble vitamins, said Pankonin.That means more vitamin A from squash, carrots, and sweet potatoes; more vitamin D from mushrooms; more vitamin E from bell peppers, leafy greens and asparagus; and more vitamin K from greens, broccoli and onions.squash n. 西葫芦asparagus n. 芦笋broccoli n. 西兰花For pan frying or sauteing, Pankonin suggests cooking with enough oil so the vegetables do not stick to the pan. The amount of oil will depend on the quantity of vegetables and the size of the pan.For roasting, you will likely need more oil. Despite the longer cooking time, roasting will still keep some nutrients and will increase the flavor with the heating of natural sugars.“Flavor is king,” Pankonin said. “I would much rather see people roasting their vegetables and enjoying them.”Part III. KEYQ1. C. 细节题。题目出处：Thomas’ simple answer to both groups is this: The best vegetables are the ones you actually want to eat. 意为：Thomas对这两类人的简单回答是“最好的蔬菜就是你真正愿意吃的蔬菜”。因此C选项正确。Q2. A. 细节题。题目出处为：Cooking changes the structure of vegetables which increases what dietitians call bioavailability. This is the body’s ability to use the nutrients in vegetables. 意为：烹饪会改变蔬菜的结构，从而增加生物利用度，即身体利用蔬菜中营养成分的能力。因此A选项正确。Q3. B. 细节题。题目出处：Boiling vegetables runs the risk of losing water-soluble nutrients including vitamin C, B1 and folate; The nutrients are “leaching into the water, and you’re tossing out the water.” 意为：煮蔬菜可能会导致水溶性营养素流失，包括维生素C、B1和叶酸；营养成分会“渗入水中，而你又把水倒掉了”。因此B选项正确。Q4. D. 推理题。题目出处：Besides making vegetables taste better, a little cooking oil helps the body to absorb fat-soluble vitamins, said Pankonin. 意为：除了让蔬菜更美味外，一点点食用油还能帮助身体吸收脂溶性维生素。因此D选项正确。Q5. B. 主旨题。题目出处为整篇文章的核心内容，尤其是“Cooking methods do affect nutrition” 和“Cooking changes the structure of vegetables which increases what dietitians call bioavailability.”。 意为：烹饪方法确实会影响蔬菜的营养；烹饪会改变蔬菜的结构，从而增加生物利用度。因此B选项正确。（本文图片来源于摄图网，版权归摄图网所有)

They are well understood and have a single cause.B. They are primarily linked to pre-existing health conditions.C. They are related to the severity of the initial COVID infection.D. They are varied and include many different abnormalities.Q3. What is the role of vaccination in relation to Long COVID, as discussed by Dr. Rylance?A. It increases the risk of developing Long COVID.B. It has no effect on the likelihood of experiencing Long COVID.C. It protects against severe COVID disease and Long COVID.D. It is ineffective once Long COVID symptoms have already begun.Q4. What can be inferred about the global impact of Long COVID and the need for healthcare recognition and support?A. Long COVID is a localized issue that requires specialized treatment centers.B. Long COVID is a widespread problem affecting diverse populations.C. Long COVID symptoms are universally recognized and treated the same way worldwide.D. Long COVID is not a significant concern for healthcare systems.Q5. What is the main idea of Dr. Rylance’s discussion on the challenges and support needed for managing Long COVID?A. The key is to raise awareness and ensure patients feel recognized and supported.B. The main focus should be on rehabilitation and improving quality of life.C. The primary challenge is developing a specific medical treatment for Long COVID.D. The most important aspect is to conduct more clinical trials for new treatments.Part II. TRANSCRIPTWHO’s Science in 5: What Is Long COVID?Vismita Gupta-Smith: If you have recovered from COVID but still have some symptoms, could that be Long COVID? How long do these symptoms last? Is there treatment available? Here to talk about Long COVID today is Dr. Jamie Rylance. Welcome, Jamie. Jamie, talk to us about Long COVID. How does it affect people?Dr. Jamie Rylance: Yeah. Thanks, Vismita, pleasure to be here. So Long COVID can happen to anybody after their acute illness. It can come on as a continuation of symptoms or new symptoms and it can last a long time. The problem is, the symptoms are very variable. Patients may have difficulty recognizing that they have it and healthcare workers, to be honest, can also struggle to identify it. (Q1) But if you’re a typical Long COVID patient, you might have fatigue, feeling tired all the time brain fog, difficulty concentrating, difficulty sleeping, shortness of breath. Those are the main symptoms, but there are so many others. One of the problems is that those symptoms can also represent other medical illnesses. So it’s really important to get the diagnosis right and healthcare workers and patients need to work together to do that. So when scientists have looked for what are the underlying causes of Long COVID, there’s many different abnormalities that have been seen. (Q2) Things like very small blood clots or altered immune cell responses, abnormal triggering or responses within the nervous system or changes in the usual bugs, the microbiome that we usually carry around with us. And that being so many different possibilities, there’s no single one diagnostic test. That said, we need to get patients onto treatment. We focus on the things that are bothering them, the symptoms, and making sure their function comes back to normal.diagnosis n. 诊断；（问题原因的）判断blood clot 血凝块；血块Vismita Gupta-Smith: Jamie, do people experience Long COVID differently? Are symptoms different and why? Dr. Jamie Rylance: Well, the obvious thing is no two people are the same and it can be very different. That said, we do know some things that might predict whether you’re more at risk of having Long COVID or for how long the symptoms might last for.Vismita Gupta-Smith: Jamie, talk to us about vaccination.Dr. Jamie Rylance: (Q3) So vaccination does help. It protects you against severe COVID disease and it protects you against Long COVID. At the other end of the spectrum, people who’ve had particularly severe disease are more likely to have Long COVID and the symptoms are likely to last longer. And that’s people who have been admitted to hospital or particularly to Intensive Care Unit. But we know that, the health of people before COVID is really important as well. So long-standing or pre-existing health problems. Respiratory disease, mental health problems but many others can increase the risk that you suffer long COVID. And therefore, it’s really important to try and keep and maintain a healthy lifestyle as much as possible. (Q4) So we know that Long COVID is a global problem. It can occur to anyone, anywhere in the world. What we need is for primary healthcare professionals to be able to recognize, assess and treat patients with Long COVID. And the way people access their healthcare will vary around the world. Sometimes there may be specialty services for COVID, sometimes there may be specialist doctors. But very frequently, and particularly where resources are limited, there are not. And so it’s really important that we empower primary healthcare providers to give patient centred care close to home. And that’s what we’re doing at WHO, making guidance to help healthcare workers deliver high-quality care and the education materials to support them to do so.respiratory adj. 呼吸的Vismita Gupta-Smith: So Jamie, how long do the symptoms last and even though we don’t have a pill, per se, how can we help people who are suffering from Long COVID? Dr. Jamie Rylance: Well, the first thing is that most people recover fully and that can take months and of course some people we know are badly affected for years. Although there isn’t a specific medical treatment, what we really need to do is access and treat patients for the problems that they have. Often that’s associated with rehabilitation, getting people back to functional status to enjoy life and health. There are specific medical treatments for some people and overall, that goes a long way to helping increase quality of life. So I’m optimistic in the science delivering more treatments and that’s hundreds of clinical trials going on at present. And I’d encourage people to get involved where they feel able and where they’re offered. So there’s hope, I think, in terms of new treatments. (Q5) But apart from the medical treatment, I think the biggest obstacle that people with Long COVID feel at the moment is that their disease is not recognized. They’re told that their brain fog or other symptoms are not real, and that’s demoralizing. So what they need is kindness and support through their treatment. And that comes from their family, their friends, their employers, because it’s in everyone’s best interest that people with Long COVID don’t feel alone and feel that they’re supported throughout their recovery. demoralizing adj. 使丧失信心的，令人泄气的Vismita Gupta-Smith: Thank you, Jamie. That was Science in 5 today. Until next time then, stay safe, stay health and stick with science.Part III. KEYQ1. B. 细节题。根据文本中的描述：“But if you’re a typical Long COVID patient, you might have fatigue, feeling tired all the time brain fog, difficulty concentrating, difficulty sleeping, shortness of breath.”可知，典型的长新冠患者可能会经历疲劳、脑雾、难以集中注意力、睡眠困难和呼吸急促等症状。因此答案为B。Q2. D. 细节题。文本中提到：“there’s no single one diagnostic test.” 以及 “Things like very small blood clots or altered immune cell responses, abnormal triggering or responses within the nervous system or changes in the usual bugs, the microbiome that we usually carry around with us.” 这表明长新冠没有单一的诊断测试，造成它的的潜在原因多种多样，包括许多不同的异常情况，如微小的血凝块、免疫细胞反应改变、神经系统的异常触发或反应以及体内微生物群的变化等。因此答案为D。Q3. C. 细节题。根据文本中的信息：“So vaccination does help. It protects you against severe COVID disease and it protects you against Long COVID." 可知，疫苗接种有助于预防重症COVID疾病和长新冠。因此答案为C。Q4. B. 推理题。文本中提到：“So we know that Long COVID is a global problem. It can occur to anyone, anywhere in the world. What we need is for primary healthcare professionals to be able to recognize, assess and treat patients with Long COVID”这表明长新冠是一个全球性问题，可以影响世界上任何人，需要基层医疗保健专业人员能够识别、评估和治疗长新冠患者。答案为B。Q5. A. 主旨题。在讨论长新冠的挑战和所需支持时，Dr. Rylance提到：“The biggest obstacle that people with Long COVID feel at the moment is that their disease is not recognized.”以及 “what they need is kindness and support through their treatment.” 这表明，长新冠患者面临的主要挑战是他们的疾病没有得到认可，他们需要的是在治疗过程中的善意和支持。因此答案为A。（本文图片来源于摄图网，版权归摄图网所有)

(Q2) Cooking changes the structure of vegetables which increases what dietitians call bioavailability. This is the body’s ability to use the nutrients in vegetables, Thomas said.bioavailability n. 生物利用度（指身体吸收和利用营养的能力）Cooked food is often more nutritious than raw food. For example, cooked tomatoes release more of the antioxidant lycopene than raw tomatoes, she said. Lycopene is believed to have qualities that prevent cancer.nutritious adj. 有营养的，营养丰富的 antioxidant n. 抗氧化剂lycopene n. 番茄红素Also, cooked carrots have more beta-carotene that can be absorbed by the body. Roasting pumpkins, carrots and sweet potatoes increases available carotenoids. These antioxidants are thought to prevent inflammation in the body.pumpkin n. 南瓜carotenoid n. 类胡萝卜素inflammation n. 炎症Which cooking methods are the healthiest?However, the shorter the cooking time, the more nutrients are kept in the food. That advice comes from Amber Pankonin, a dietitian in the U.S. state of Nebraska.Cooking over boiling water, or steaming, and in a microwave are considered the most nutritious methods. These two methods use little time and require no fat.Another healthy method is blanching. This is when you boil vegetables in water for a minute or two. But not too long. (Q3) Boiling vegetables runs the risk of losing water-soluble nutrients including vitamin C, B1 and folate. Thomas explained the reason boiling is not good for vegetables: The nutrients are “leaching into the water, and you’re tossing out the water.”blanch v. 焯水，焯烫folate n. 叶酸leach v. （液体）过滤，浸出However, you could save the water from boiled vegetables and use it for other purposes, such as soups, or just drink it.What about taste?Dietitians say there is no problem using a small amount of fat. (Q4) Besides making vegetables taste better, a little cooking oil helps the body to absorb fat-soluble vitamins, said Pankonin.That means more vitamin A from squash, carrots, and sweet potatoes; more vitamin D from mushrooms; more vitamin E from bell peppers, leafy greens and asparagus; and more vitamin K from greens, broccoli and onions.squash n. 西葫芦asparagus n. 芦笋broccoli n. 西兰花For pan frying or sauteing, Pankonin suggests cooking with enough oil so the vegetables do not stick to the pan. The amount of oil will depend on the quantity of vegetables and the size of the pan.For roasting, you will likely need more oil. Despite the longer cooking time, roasting will still keep some nutrients and will increase the flavor with the heating of natural sugars.“Flavor is king,” Pankonin said. “I would much rather see people roasting their vegetables and enjoying them.”Part III. KEYQ1. C. 细节题。题目出处：Thomas’ simple answer to both groups is this: The best vegetables are the ones you actually want to eat. 意为：Thomas对这两类人的简单回答是“最好的蔬菜就是你真正愿意吃的蔬菜”。因此C选项正确。Q2. A. 细节题。题目出处为：Cooking changes the structure of vegetables which increases what dietitians call bioavailability. This is the body’s ability to use the nutrients in vegetables. 意为：烹饪会改变蔬菜的结构，从而增加生物利用度，即身体利用蔬菜中营养成分的能力。因此A选项正确。Q3. B. 细节题。题目出处：Boiling vegetables runs the risk of losing water-soluble nutrients including vitamin C, B1 and folate; The nutrients are “leaching into the water, and you’re tossing out the water.” 意为：煮蔬菜可能会导致水溶性营养素流失，包括维生素C、B1和叶酸；营养成分会“渗入水中，而你又把水倒掉了”。因此B选项正确。Q4. D. 推理题。题目出处：Besides making vegetables taste better, a little cooking oil helps the body to absorb fat-soluble vitamins, said Pankonin. 意为：除了让蔬菜更美味外，一点点食用油还能帮助身体吸收脂溶性维生素。因此D选项正确。Q5. B. 主旨题。题目出处为整篇文章的核心内容，尤其是“Cooking methods do affect nutrition” 和“Cooking changes the structure of vegetables which increases what dietitians call bioavailability.”。 意为：烹饪方法确实会影响蔬菜的营养；烹饪会改变蔬菜的结构，从而增加生物利用度。因此B选项正确。（本文图片来源于摄图网，版权归摄图网所有)

TRANSCRIPTReport: Language, Traditions Central to National IdentityLuciana de Oliveira considers herself transnational. That means she is more than one nationality. de Oliveira grew up in Brazil, but she moved to the United States for her studies. She became a U.S. citizen in 2017.transnational adj. 跨国的；多国的de Oliveira has some strong feelings about national identity. She believes speaking a country’s majority language is a very important part of one’s national identity. de Oliveira speaks both Portuguese and English.A new study found that most people around the world share those feelings about language and national identity.The Pew Research Center carried out the study and released the results last month. Pew’s study centered on people’s ideas about national identity. It included answers from people in more than 20 countries.(Q1) Pew researchers asked study participants about four aspects, or parts, of national identity: language, traditions, birthplace and religion. They found that language is by far the most valued aspect of national identity.In fact, a median of 91 percent of people across 21 countries said that speaking a country’s most common language is “important for being considered a true national.”Traditions and customs are also key to national identity, the study found. Beliefs about the other two aspects – birthplace and religion – were more divided.VOA Learning English spoke with several people who live in countries that were included in the study. Among them is Jorge Catalan. He has lived in Mexico most of his life. The Pew study found that 93 percent of respondents from Mexico said that speaking the country’s main language – Spanish – is important to national identity.Catalan said he agrees that speaking Spanish is very important. But he added that it is regrettable.He said, “Mexico is a place where we have around 68 spoken languages besides Spanish.” He noted that the government has pushed Spanish as the main language throughout history and has turned it into a “must-have tool.”Agatha Janzen was born and raised in Canada. Pew researchers found that more than 80 percent of Canadians say that speaking the country’s language is important to national identity. In Canada, both French and English are official languages.Janzen said that “speaking one of the official languages is important to being Canadian for practical reasons.”(Q1) Traditions and customs are also a central aspect of national identity, the study found. Results showed 81 percent of people believe sharing their country’s customs and traditions is somewhat or very important to national identity.The Pew study found that 67 percent of Brazilians consider practicing customs and traditions an important part of national identity. That is the fourth lowest percentage of all the countries included in the study.But customs and traditions are important to de Oliveira. To feel closer to her Brazilian identity, she said she wears jewelry and shoes from Brazil and follows and supports Brazilian soccer.Mexico is tied with the highest percentage of respondents who answered that customs and traditions are an important aspect of national identity. But for Catalan, they are not so important. He noted that Mexican traditions have changed over time. He added that he does not take part in many Mexican traditions, “but I still feel proudly Mexican.”Beliefs about the two other aspects of national identity – birthplace and religion – were more mixed. A median of 58 percent of respondents from 23 countries said that being born in a country is important to national identity. An even lower number of respondents – 42 percent – said that being a member of the country’s main religion is important to national identity.(Q2) Respondents from Mexico and Indonesia had the strongest feelings about the importance of birthplace as central to national identity, at 91 percent.Calatan, who was born and lived most of his life in Mexico, agrees somewhat. “If you are born outside of Mexico and never lived in it, it would be difficult to get a real sense of what being Mexican means.”(Q3) But Janzen, the Canadian, said, “Being born in Canada has nothing to do with being Canadian.” For her, Canada is a melting pot and offers refuge to those who need it.refuge n. 庇护；避难These ideas match the results of the study. Countries where immigrants make up a smaller share of the population tend to see birthplace as a more important aspect of national identity. (Q4) Countries with a greater share of immigrants are more willing to accept those born outside of the country as true nationals.Less than half of people in most of the countries in the study do not feel religion is important to national identity. All of those who spoke with Learning English said they agreed that religion is not an important part of national identity.Christine Huang is a research associate at the Pew Research Center. She is one of the writers of the study. She told Learning English, “This question of belonging in a country is related to other work we have done to measure how connected people feel to each other.”Huang added, “When looking at how people relate to others in their community, in their country, and all over the world, people most frequently report feeling close to others in their country.”|Part III. KEYQ1. A. 主旨题。文本中提到：“Pew researchers asked study participants about four aspects, or parts, of national identity: language, traditions, birthplace and religion. They found that language is by far the most valued aspect of national identity.” 以及“Traditions and customs are also a central aspect of national identity, the study found.”这表明研究参与者普遍认为语言和传统是民族身份最重要的部分，所以民族身份主要由一个人的语言和传统塑造。因此答案为A。Q2. C. 细节题。文本中提到：“Respondents from Mexico and Indonesia had the strongest feelings about the importance of birthplace as central to national identity, at 91 percent.” 这表明墨西哥和印度尼西亚的受访者中有91%的人认为出生地对于民族身份认同至关重要。因此答案为C。Q3. B. 推理题。Janzen表示：“Being born in Canada has nothing to do with being Canadian. For her, Canada is a melting pot and offers refuge to those who need it.” 这表明 Janzen 认为出生在加拿大与成为加拿大人无关，加拿大是一个大熔炉，为需要的人提供庇护，这意味着加拿大的民族身份认同是包容性的，不严格依赖于任何单一标准，如出生地或语言。因此答案为B。Q4. D. 推理题。文本中提到：“Countries with a greater share of immigrants are more willing to accept those born outside of the country as true nationals.” 这意味着拥有更多移民的国家更愿意接受在外国出生的人作为真正的国民，可推测出他们认为出生地对于国家身份认同不那么重要。因此答案为D。Q5. C. 主旨题。文本通过展示不同国家和个体对于语言、出生地和宗教在民族身份中重要性的不同看法，表明民族身份的概念在不同人群和国家之间存在差异。特别是对于出生地和宗教的看法更为混合，这表明民族身份的构成因素在不同文化和个体中有着不同的解读。因此答案为C。（本文图片来源于摄图网，版权归摄图网所有)
