Shoes off please.” In many Asian countries, removing shoes when you enter someone’s home is expected – it shows respect and ensures cleanliness. In other places, such as the UK, however, the social norms are more ambiguous. Some Brits might have a strict “shoes off” rule, while others may be squeamish about seeing others’ socks or bare feet. What do the scientists say?squeamish adj. 易感到不适的，易受惊的If you remove your shoes at the door for cleanliness, you’re probably thinking about the visible dirt – urban dust, mud and grass that has hitched a ride from the outside world on the sole of your shoe. But the real problems are microscopic. (Q1) A review of research called ‘Shoe soles as a potential vector for pathogen transmission’ found a high prevalence of dangerous bacteria on shoe soles, which could lead to illness. Children under five are particularly at risk because of their closeness to the floor and developing immune systems.sole n. 鞋底vector n. 传播媒介，载体pathogen n. 病原体 Germs aside, shoe soles can also bring in nasty chemicals like pesticides and herbicides, (Q2) exposure to which can cause headaches, dizziness, nausea and vomiting, according to a study by Muhammad Sarwar, published in Cogent Medicine. Allergens such as pollen can also enter your home via your shoes, which can be a big issue if you suffer with hay fever or have respiratory issues. Isn’t your home meant to be a safe haven?herbicide n. 除草剂allergen n. 过敏原pollen n. 花粉hay fever 花粉病But it’s not just about hygiene. (Q3) Going shoeless can improve things such as balance, body awareness and strength and stability in your muscles, according to a medically reviewed article called ‘Does Walking Barefoot Have Health Benefits?’. “In theory, walking barefoot more closely restores our ‘natural’ walking pattern, also known as our gait,” explains foot and ankle specialist Jonathan Kaplan.gait n. 步态，步法(Q4) In cultures where a shoe-free home is the norm, the reasons are backed by science. And in places where the rules are less clear, maybe it’s time to think about leaving our outdoor shoes at the threshold. There’s an old African proverb that states “When you leave your shoes at the doorstep, you leave your troubles behind.”Part III.

To explain the health benefits of evening showers.B. To discuss the impact of showering on sleep quality.C. To highlight the importance of showering daily.D. To compare the advantages of morning and evening showers.Part II. TRANSCRIPTMorning shower or evening shower: Which is best? Do you need an energizing blast of water in the morning to wake you up for the day? Or do you prefer a relaxing, warm shower in the evening to help you wind down as part of your nighttime routine? Maybe you just shower whenever you feel like it. For something so many of us do, this topic is bound to divide opinion and stir up passion from both sides. But is one really better than the other?After a long day in the outside world, picking up pollutants and allergens on your skin and in your hair such as dust and pollen, a reasonable instinct would be to wash it all off before getting into bed. That’s what the evening shower enthusiasts would say. But, says microbiologist Primrose Freestone, no matter the air temperature, you will continue to sweat during the night. Bacteria on your skin then eat the nutrients in your sweat which is what causes BO. Showering at night also doesn’t stop you shedding dead skin cells. All this means you may not wake up feeling as fresh as you had hoped. [Q1] Showering in the morning, on the other hand, can help to remove dead skin cells, sweat or any bacteria you’ve picked up from your bed sheets. “As a microbiologist, I am a day shower advocate,” she says.allergens n. 过敏原pollen n. 花粉nutrient n. 营养物质microbiologist n. 微生物学家BO (body odor) 汗臭，体臭But it’s not all about cleanliness. Nancy Rothstein, who calls herself The Sleep Ambassador, is concerned with sleep quality. (Q2) In her view, showering in the evening is an essential part of the ‘preparing for bed’ routine. “Call it an opportunity to shower yourself with mindfulness,” she says. And research backs this up. (Q3) A systematic review of research published in Sleep Medicine Reviews in 2019 found nightly warm showering or bathing one to two hours before bedtime can improve sleep.(Q4) What it all boils down to is when you would like to feel freshest. If you’re someone who can’t fully relax in bed until you’ve showered, you’re likely an evening shower person. Whereas, if you can’t stand the idea of putting on fresh, clean clothes in the morning when you haven’t showered, then a morning rinse is probably more your style. Whenever you choose to shower, Primrose Freestone says it’s important to clean your bed sheets regularly to remove all the sweat, bacteria and dead skin cells that build up and can negatively affect the effectiveness of your showers.rinse n. 冲洗Part III. KEYQ1.【答案】A【解析】细节题。题目出处：Showering in the morning, on the other hand, can help to remove dead skin cells, sweat or any bacteria you’ve picked up from your bed sheets. 意为：早上洗澡可以帮助去除床单上的死皮细胞、汗液或任何细菌。正确答案为A。Q2.【答案】B【解析】细节题。题目出处：In her view, showering in the evening is an essential part of the ‘preparing for bed’ routine. 意为：在她看来，晚上洗澡是“准备就寝”过程中必不可少的一环。正确答案为B。Q3.【答案】C【解析】细节题。题目出处：A systematic review of research published in Sleep Medicine Reviews in 2019 found nightly warm showering or bathing one to two hours before bedtime can improve sleep. 意为：2019年发表在《睡眠医学评论》上的一项系统性研究发现，每晚在睡前一到两个小时进行温水淋浴或沐浴可以改善睡眠。正确答案为C。Q4.【答案】A【解析】推理题。题目出处：What it all boils down to is when you would like to feel freshest. 意为：归根结底，这取决于你想在什么时候感觉最清爽。由此可以推断，选择早上或晚上洗澡取决于个人偏好和生活方式，因此正确答案为A。Q5.【答案】D【解析】主旨题。整篇文章主要讨论了早上洗澡和晚上洗澡的优缺点，并比较了它们的不同效果。因此正确答案为D。 （本文图片均来源于网络，仅供学习交流使用，侵删）

To discuss the economic effects of air pollution.D. To analyze the history of air pollution in major cities.Part II. TRANSCRIPTAir pollution damages young brainsVGS: What if the air your child is breathing is harming their brain? Stealing them of their chance to learn, thrive and grow? This invisible danger is real, urgent and happening now. We are talking about air pollution and its impact on our brain, and what countries are doing to stop it, from London to Bogota. New studies have emerged linking air pollution to dementia, anxiety and depression affecting your brain and mental health. We are talking to Doctor Maria Neira today. Welcome, Maria. Let’s start with the impact of air pollution on our health.dementia n. 痴呆MN: Thanks Vismita. Yes. Air pollution is the biggest environmental risk factor for our health. Every year we have 7 million deaths caused by exposure to air pollution. This is a horrible number. Let me give you another figure. Nine out of ten people in the world is breathing air, which quality’s not aligned with the recommendations, the guidelines of the World Health Organization. Those little tiny particles in the polluted air, they can go very deep in our lungs. And they can affect as well our brain. (Q1) But air pollution is not just affecting our lungs and our brain; it’s affecting as well the rest of our body responsible for stroke, cardiovascular diseases, asthma, and even lung cancer.align v. 对齐，使一致cardiovascular adj. 心血管的asthma n. 哮喘VGS: So, Maria, you talked about the tiny particles, the PM 2.5 and PM10 that we’ve all heard about, right. But it’s not just that. It’s also the gases, the carbon monoxide, ozone, etc., right? I remember when we were in New Delhi, our child, my daughter, was very young at that time. We worried about her lung health, but we also worried about her cognitive development in that kind of air pollution. Can you elaborate on the impact of air pollution on children’s health?monoxide n. 一氧化物cognitive adj. 认知的MN: Let me give you an example. When you are pregnant, if you are exposed to high levels of pollution, then you might be at risk of low birth weight, premature birth, and even problems from the development of the fetus. As a child, this child, exposed to high levels of pollution, will have difficulties and more likely to develop asthma, for instance, in later in life, chronic health issues. In addition to that, (Q2) children are obviously more at risk first because they are on development. They have little lungs in their bodies developing, and then they breathe faster than we do. So they take more quantity of air for their size, and they play outside so that we have more exposure and they cannot control the exposure. So it’s our responsibility to protect them and make sure that the health of our children is develop in a healthy environment.fetus n. 胎儿VGS: Maria, if nine out of ten people are breathing polluted air, how can we protect our health?MN: We definitely have some individual measures we can take. We can reduce exposure by avoiding maybe the most trafficked roads or the most congested areas in the city where you leave for avoiding to practice a sport or walking in those very polluted places, (Q3) or even at home looking at the fuels you use for cooking and making sure that you use the cleanest possible ones. However, those are the individual choices and you are not always able to take those choices. (Q4) So it’s more a question of governments taking very bold legislation, measures and interventions to protect all of us.trafficked adj. 交通繁忙的congested adj. 堵塞的，拥挤的VGS: So, Maria, we know that this feels overwhelming, right? Feels like what can individuals do? Can you give us examples of cities or countries where this has been turned around and air pollution has been reduced drastically?MN: Absolutely. And we have perfect demonstration that it can be done. For instance, the European Union, the European Parliament has just adopted a directive on air quality, which is very much aligned to WTO recommendations and guidelines. That will create a big protection for the health of the Europeans under that legislation. We have examples as well in China, where they have demonstrated that you can reduce air pollution while still maintaining a good economic growth. And then cities, you can obtain incredible results. (Q5) The mayor of Paris has been able to reduce by 50% in the last 20 years the air pollution and therefore all the diseases associated by putting in place some traffic recommendations, green spaces, and more lines for pedestrians and bicycles. We have the London experience as well ultra low emissions zones, demonstrating that air pollution was reduced and respiratory diseases associated. (We) have Colombia. In Bogota, they are putting in place a fleet of buses which are 100% electric. And so there are very good examples. There are many, but we need to push for more. And of course, imagine where everybody will be aware and putting in place these directives and recommendations. It would be a healthier environment for all of us and our health will be so much benefited.ultra adj. 超级的respiratory adj. 呼吸的VGS: Thank you Maria. That was Science in Five today. And until next time then, stay safe, stay healthy, and stick with science.Part III. KEYQ1.【答案】A【解析】细节题。题目出处：But air pollution is not just affecting our lungs, and our brain is affecting as well the rest of our body responsible for stroke, cardiovascular diseases, asthma, and even lung cancer. 意为：空气污染不仅影响我们的肺和大脑，还影响我们的身体其他部分，导致中风、心血管疾病、哮喘，甚至肺癌。因此正确答案为A。Q2.【答案】D【解析】细节题。题目出处：Children are obviously more at risk first because they are on development. They have little lungs in their bodies developing, and then they breathe faster than we do. 意为：儿童显然更容易受影响，首先是因为他们处于发育阶段；他们的肺部还在发育，并且呼吸频率比我们快。因此正确答案为D。Q3.【答案】B【解析】细节题。题目出处：... even at home looking at the fuels you use for cooking and making sure that you use the cleanest possible ones. 意为：甚至在家里，也要检查你用来做饭的燃料，确保使用尽可能清洁的燃料。因此正确答案为B。Q4.【答案】C【解析】推理题。题目出处：So it’s more a question of governments taking very bold legislation, measures and interventions to protect all of us. 意为：所以更重要的是政府采取非常大胆的立法、措施和干预来保护我们所有人。由此可以推断，玛丽亚认为政府采取果断措施是解决空气污染的关键，因此正确答案为C。Q5.【答案】A【解析】细节题。题目出处：The mayor of Paris has been able to reduce by 50% in the last 20 years the air pollution. 意为：巴黎市长在过去20年里将空气污染减少了50%。因此正确答案为A。Q6.【答案】B【解析】主旨题。文章主要讨论了空气污染对健康的影响，并提供了可能的解决方案。题目出处：We are talking about air pollution and its impact on our brain.

TRANSCRIPTIs pollution causing your COPD?VGS: We’re standing next to this big no smoking sign in the W.H.O. headquarters. And also we’re standing next to a very busy street. Air pollution and tobacco smoking. Two of the biggest risk factors for disease we are going to talk about today — chronic obstructive pulmonary disease. Sarah, a lot of people may not know what chronic obstructive pulmonary disease or COPD is, even if they may have the disease and may not know how to recognize it. Talk to us about what it is.pulmonary adj. 肺的，与肺有关的SR: So COPD is a group of conditions which affect the lungs of adults and cause obstruction of the airways, chronic bronchitis or emphysema or other terms that you might have heard to talk about this. In COPD, we have damage and we have inflammation to different parts of the airways. Depending on which parts are affected, it can affect people differently, and this can lead to different symptoms.bronchitis n. 支气管炎emphysema n. 肺气肿 VGS: So, Sarah, if people have COPD, how would they know what is actually happening inside us?SR: So the symptoms of COPD come on slowly and often become worse gradually. Someone might notice, for example, that they are having difficulty going about their normal daily life. Sometimes people notice first that they’re having difficulty in walking, particularly going up a hill. Or if they have to take the stairs, they may become breathless. As things progress, it might become that they then start to find it difficult to get dressed in the morning, for example, or to do normal daily household chores. In severe cases, it can become so bad that people are breathless even when they are talking or eating. Sometimes symptoms can become suddenly worse as well. This is called a flare-up or an exacerbation. At that time, people would need to get additional medical treatment. Sometimes they even needed to be admitted to hospital for that. The exact symptoms depend on what is happening inside of the lungs. So if I have chronic bronchitis, then my airways are inflamed. They’re swollen, there’s mucus. And so if I have that, then I will be coughing or I’ll be coughing up phlegm or mucus. And I might also be breathless. In emphysema, (Q1) we find that at the end of the airways there are little air sacs, and these can become damaged. And then air collects in these air sacs, and it means that people can’t breathe out fully, so their lungs are overinflated. They have this feeling of their lungs being full all of the time, and it creates a feeling of breathlessness.exacerbation n. 加重，恶化inflame v. 使发炎，激怒mucus n. 粘液，痰phlegm n. 痰，黏液sac n. 囊，气囊VGS: Other than smoking and air pollution, what are the causes of COPD?SR: There are lots of different things that can cause COPD. In the past, people really attributed COPD to smoking, and your risk of COPD increases with the more cigarettes that you smoke every day or the longer that you’ve smoked for. But we now know there are other things too. Air pollution is one that you’ve mentioned. (Q2) This could be indoor air pollution. So exposure through when people are cooking on biomass fuels, for example, like wood or charcoal inside an enclosed space, or outdoor air pollution from traffic or from industry factories, these kinds of things.biomass n. 生物质燃料（如木材、木炭等）charcoal n. 木炭，炭VGS : Sarah, are some people more susceptible to COPD?SR: So actually, yes, our lungs start growing and developing even before we are born, and they continue to grow and develop throughout childhood, throughout teenage years until they reach their maximum potential in your early 20s. (Q3) If you’re exposed to things during that period of lung growth and development that stop your lungs from growing and developing in this way, then this means that you never reach that full potential and you’re at increased risk of COPD. If your mother smokes, or is exposed to air pollution or tobacco smoke during pregnancy. If you’re born very small or born early, if you have severe respiratory infections during childhood, all of these things impact your lung growth and development. That means you reach adulthood without having grown your lungs to their full size, if you like. So you’re at more risk of developing COPD. (Q4) Asthma is another risk factor. If people have asthma in childhood, particularly if it’s poorly treated, then that can be a risk factor. There are also some genetic conditions that can predispose to COPD.respiratory adj. 呼吸的，呼吸系统的asthma n. 哮喘genetic adj. 遗传的，基因的predispose v. 使倾向于，预先安排VGS: So that’s actually alarming, that if a mother is breathing air pollution and is a smoker, then the chances of the child developing COPD increases, especially alarming because nine out of ten people are breathing air that’s unhealthy for them. Is there a treatment for COPD?SR: (Q5) If COPD is diagnosed early and appropriate treatment is started promptly, then people with COPD can live as full of a life as possible. (Q6) Remember, it’s not normal to be breathless, and it’s not just people who smoke that get COPD. (Q7) The important things are firstly, to stop smoking if people smoke. (Q8) Secondly, to take regular exercise, and there are special programs called pulmonary rehabilitation for people with COPD to help strengthen their lungs. Thirdly, there are various inhaled treatments that are available which work in different ways inside the lungs that can be helpful. Lastly, (Q9-1) it’s very important to protect from infection. So if someone has COPD, (Q9-2) it’s really important that they get vaccinated against flu and Covid, for example, other respiratory infections.inhale v. 吸入，吸气vaccinate v. 给…接种疫苗VGS: Thank you, Sarah. That was science and five today. Until next time then, stay safe, stay healthy, and stick with science. Part III. KEYQ1. B.【解析】细节题。根据“at the end of the airways there are little air sacs, and these can become damaged. And then air collects in these air sacs, and it means that people can’t breathe out fully, so their lungs are overinflated.”，可知在气道的末端有小气囊，这些可能会受损。然后空气会积聚在这些气囊中，导致患者无法完全呼出气体，肺部过度膨胀，由此可以推断气囊的主要功能是气体交换。因此答案为B。Q2. C.【解析】细节题。根据“This could be indoor air pollution. So exposure through when people are cooking on biomass fuels, for example, like wood or charcoal inside an enclosed space...”，可知室内空气污染，比如人们在封闭空间内使用使用木材、木炭等生物质燃料做饭时接触到的污染物而增加COPD的风险。因此答案为C。Q3. A.【解析】细节题。根据“If you’re exposed to things during that period of lung growth and development that stop your lungs from growing and developing in this way, then this means that you never reach that full potential and you’re at increased risk of COPD.”，可知如果在肺生长发育期间接触到阻止肺其正常发育的物质，那么肺部就无法达到应有的发育水平，你患COPD的风险就会增加。由此可知，早期接触污染物可能会永久阻碍肺的生长。因此答案为A。Q4. D.【解析】推理题。根据“Asthma is another risk factor. If people have asthma in childhood, particularly if it’s poorly treated, then that can be a risk factor.”，可知哮喘是另一个风险因素。如果人们在儿童时期患有哮喘，特别是如果治疗不当，那么这可能是一个风险因素。由此推理，通过在儿童时期有效治疗哮喘可以预防或减缓COPD的发展。因此答案为D。Q5. B.【解析】主旨题。整个对话都在讨论COPD的症状、原因和治疗方法，特别是在“if COPD is diagnosed early and appropriate treatment is started promptly, then people with COPD can live as full of a life as possible.”这句话中强调了尽管COPD是是不可治愈的，但若早期诊断并及时治疗，是可以控制的。因此答案为B。Q6. D.【解析】推理题。根据“Remember, it’s not normal to be breathless, and it’s not just people who smoke that get COPD.”，可知气喘不是正常现象，而且不仅仅是吸烟的人会得COPD。这句话是在提醒COPD患者不应该将气喘视为一种正常状态，而应该及时寻求诊断和治疗。因此答案为D。Q7. B.【解析】细节题。根据“The important things are firstly, to stop smoking if people smoke.”，可知管理COPD的第一步就是戒烟。因此答案为B。Q8. A.【解析】细节题。根据“Secondly, to take regular exercise, and there are special programs called pulmonary rehabilitation for people with COPD to help strengthen their lungs.”，可知，肺康复对于COPD患者来说，是通过定期锻炼来帮助加强肺部功能。因此答案为A。Q9. C.【解析】细节题。根据“it’s very important to protect from infection”以及“it’s really important that they get vaccinated against flu and Covid, for example, other respiratory infections.”，可知接种流感和Covid疫苗非常重要，可以保护患者免受流感和其他呼吸道感染。因此答案为C。（本文图片来源于摄图网，版权归摄图网所有)

TRANSCRIPTTips for Better WritingToday we continue our series of expert suggestions for academic writing. Our guest is Jennifer Ahern-Dodson, assistant professor of the Practice in Writing Studies at Duke University in North Carolina.Ms. Ahern-Dodson starts a conversation with both students and professors planning to write a paper or essay. (Q1) She asks about their earlier writing experiences. Were they negative or positive?She advises that you are not alone if you have had problems with your writing. She says everyone struggles with writing.“Writing is hard. All writers struggle at some point. And even if writing has come easily for you, at some point in your work as a student, that eventually you’re going to hit a roadblock. And so part of what I like to get folks thinking about is — besides writing’s hard for everybody — is to really take a moment to think about their past writing experiences. And when the writing is going well, what was happening? When the writing wasn’t going well, what was happening?”She says most people’s negative writing experiences happened because a very special formula is required for a paper including an exact length.“(Q2) And so they primarily focus on, and worry about, what the final product has to look like, like how many pages for a research essay? Or if it is in the second or third language, you know, punctuation and grammar, like whether it gets communicated in the right language.”punctuation n. 标点符号“And so focusing on the end makes it really hard to get started.”Another problem can arise when the need to do well on a paper is extremely important.“...like a timed essay exam, or a college application essay, or a research paper that is at the end of the semester, and it’s tied to the entire grade for the class. (Q3) So worrying about what will happen if they don’t do well — get bad grades, don’t get into college — creates, of course, significant anxiety. And that can make it harder to get the writing done.”Then she and the people she’s helping move to more positive projects. She says usually when writing comes easily, the writers feel they have something important to say.The teacher advises asking yourself questions. What personal understanding of the subject can you bring to your paper? Why is this subject important? For whom is it meaningful? Who will be reading it?“(Q4) Think about who your audience is, and what it is that you really want to say to them. And what that can do is help you switch from the final product and what it can look like (to) really more on what you have to offer, your particular perspective.”She says that is an important change for all writers.Part III. KEYQ1. B.【解析】细节题。根据“She asks about their earlier writing experiences. Were they negative or positive?”，可知Dodson她关注的是他们之前写作的经历，是消极的还是积极的。因此答案是B。Q2. C.【解析】细节题。根据“And so they primarily focus on, and worry about, what the final product has to look like, like how many pages for a research essay?”，可知学生们主要关注并担心最终产品的样子，比如研究论文需要多少页？这表明学生在写作时最关心的是论文的确切长度和格式要求。因此答案是C。Q3. B.【解析】推理题。根据“So worrying about what will happen if they don’t do well ... creates, of course, significant anxiety. And that can make it harder to get the writing done.”，可知担心表现不佳会产生焦虑，而这种焦虑会使写作变得更加困难。因此答案是B。Q4. D.【解析】细节题。根据“Think about who your audience is, and what it is that you really want to say to them.”，可知Dodson建议作家思考他们的读者是谁，以及他们真正想要传达的信息，以帮助他们从过分关注最终产品，转向更关注自己想要提供的内容上。因此答案是D。Q5. A.【解析】主旨题。整个文本的主旨在于提供写作建议，这可以从标题“Tips for Better Writing”和整个报道的内容中得出。因此答案是A。（本文图片来源于摄图网，版权归摄图网所有)
