教学素材 | 眼睛里的漂浮物是什么？

眼睛里的漂浮物是什么？What are those floaty things in your eye?词汇：考研 | 句法：六级| 文本：考研刘立军供稿Have you ever noticed something swimming in your field of vision? It may look like a tiny worm or a transparent blob, and whenever you try to get a closer look, it disappears, only to reappear as soon as you shift your glance. But don’t go rinsing out your eyes! What you are seeing is a common phenomenon known as a floater.你是否曾经注意到视野中有东西在游动？它可能看起来像一条小虫子或一个透明的斑点，而每当你试图仔细看时，它却消失了，只有在你转移视线时又重新出现。但别急着去冲洗眼睛！你看到的是一种常见的现象，称为“飞蚊症”。The scientific name for these objects is Muscae volitantes, Latin for "flying flies," and true to their name, they can be somewhat annoying. But they’re not actually bugs or any kind of external objects at all. Rather, they exist inside your eyeball.这些物体的科学名称是Muscae volitantes，拉丁语意为“飞舞的苍蝇”。正如其名，它们确实有些烦人。但它们并不是虫子，也不是任何外部物体，而是存在于你的眼球内部。Floaters may seem to be alive, since they move and change shape, but they are not alive. Floaters are tiny objects that cast shadows on the retina, the light-sensitive tissue at the back of your eye. They might be bits of tissue, red blood cells, or clumps of protein.“飞蚊”看起来像是活的，因为它们会移动并改变形状，但实际上，它们并不是生物。“飞蚊”是投射在视网膜（眼球后部对光敏感的组织）上的微小物体。它们可能是组织碎片、红细胞或蛋白质团块。And because they’re suspended within the vitreous humor, the gel-like liquid that fills the inside of your eye, floaters drift along with your eye movements, and seem to bounce a little when your eye stops.由于它们悬浮在玻璃体（一种充满眼球内部的凝胶状液体）中，“飞蚊”会随着眼球的运动而漂移，并在眼球停止移动时似乎轻轻弹跳。Floaters may be only barely distinguishable most of the time. They become more visible the closer they are to the retina, just as holding your hand closer to a table with an overhead light will result in a more sharply defined shadow.大多数时候，“飞蚊”几乎难以察觉。它们越靠近视网膜，就越明显，就像将手靠近桌面时，在顶灯下会产生更清晰的阴影一样。And floaters are particularly noticeable when you are looking at a uniform bright surface, like a blank computer screen, snow, or a clear sky, where the consistency of the background makes them easier to distinguish. The brighter the light is, the more your pupil contracts. This has an effect similar to replacing a large diffuse light fixture with a single overhead light bulb, which also makes the shadow appear clearer.当你注视一片均匀明亮的表面时，比如空白的电脑屏幕、雪地或晴朗的天空，“飞蚊”尤其显眼，因为背景的一致性让它们更容易被分辨出来。光线越亮，瞳孔收缩得越多。这种效果类似于用一盏顶灯替换大面积的散射光源，这也会使阴影变得更清晰。There is another visual phenomenon that looks similar to floaters but is in fact unrelated. If you’ve seen tiny dots of light darting about when looking at a bright blue sky, you’ve experienced what is known as the blue field entoptic phenomenon.还有另一种视觉现象看起来与“飞蚊”相似，但其实并无关联。如果你在注视明亮的蓝天时看到有微小的光点在飞舞，那么你经历的就是所谓的“蓝场内视现象”。In some ways, this is the opposite of seeing floaters. Here, you are not seeing shadows but little moving windows letting light through to your retina. The windows are actually caused by white blood cells moving through the capillaries along your retina’s surface.在某些方面，这与看到“飞蚊”正好相反。这里，你看到的不是阴影，而是让光线透过的小“窗口”。这些“窗口”实际上是白细胞沿着视网膜表面的毛细血管移动造成的。These leukocytes can be so large that they nearly fill a capillary causing a plasma space to open up in front of them. Because the space and the white blood cells are both more transparent to blue light than the red blood cells normally present in capillaries, we see a moving dot of light wherever this happens, following the paths of your capillaries and moving in time with your pulse.这些白细胞可能会大到几乎填满毛细血管，从而在它们前面形成一个血浆空间。由于这些空间和白细胞对蓝光的透明度比毛细血管中的红细胞更高，因此无论何时发生这种情况，我们都会看到一个移动的光点，沿着毛细血管的路径移动，并与脉搏同步。Under ideal viewing conditions, you might even see what looks like a dark tail following the dot. This is the red blood cells that have bunched up behind the leukocyte.在理想的观察条件下，你甚至可能看到光点后面有一个类似暗尾的东西。这是堆积在白细胞后面的红细胞。Some science museums have an exhibit which consists of a screen of blue light, allowing you to see these blue sky sprites much more clearly than you normally would.一些科学博物馆设有蓝色光屏展览，让你能够比平时更清楚地看到这些“蓝天精灵”。While everybody’s eyes experience these sort of effects, the number and type vary greatly. In the case of floaters, they often go unnoticed, as our brain learns to ignore them. However, abnormally numerous or large floaters that interfere with vision may be a sign of a more serious condition, requiring immediate medical treatment.虽然每个人的眼睛都会经历这类现象，但其数量和类型差异很大。对于“飞蚊”来说，它们通常会被忽视，因为大脑学会了忽略它们。然而，如果“飞蚊”数量异常多或体积过大，干扰了视力，则可能是某种严重疾病的征兆，需要立即就医。But the majority of the time entoptic phenomena, such as floaters and blue sky sprites, are just a gentle reminder that what we think we see depends just as much on our biology and minds as it does on the external world.但大多数时候，像“飞蚊”和“蓝天精灵”这样的内视现象只是温和地提醒我们，我们所“看见”的内容不仅取决于外部世界，也取决于我们的生物学特性和思维。【词汇】 1. blob n.（不规则的）斑点，团状物2. retina n. 视网膜3. clump n. 团块，聚集物4. vitreous humor n. 玻璃体液，玻璃状液5. entoptic adj. 眼内的，内视的6. leukocyte n. 白细胞7. capillary n. 毛细血管8. plasma n. 血浆，等离子体9. sprite n. 小精灵，幽灵（本文图片来源于摄图网，版权归摄图网所有)

To highlight the importance of avoiding naps entirely. B. To discuss the link between naps and cardiac health. C. To analyze the role of circadian rhythms in sleep. D. To explain the benefits and drawbacks of napping. Part II. TRANSCRIPTNaps might not be as good for you as you think Surely, they're called power naps for a reason? Aren't naps the key to feeling alert, improving your memory and just generally having a great life? Well, they can be, but things aren't quite that simple.(Q1) It is true that a short nap can help people be more alert, improve their memory and concentration, and reduce risks around tasks with heavy machinery. Our circadian rhythms are responsible for the notorious lull that many of us feel in the early afternoon. This is the best time for a nap. Some companies have installed sleep pods for their employees, hoping to benefit from increased productivity and cognitive performance. But it is also true that naps can cause problems.circadian adj. 生理节奏的，昼夜节律的 notorious adj. 声名狼藉的，众所周知的（常指不好的事情） lull n. 间歇，平静期 pod n. 小舱，隔间 cognitive adj. 认知的 Let's start by thinking about the length. (Q2) A true power nap should be less than half an hour. Any longer, and it becomes hard to rouse yourself from. Any benefits in terms of alertness are likely to disappear with the grogginess that results from a longer period of slumber.grogginess n. 昏昏沉沉，虚弱无力slumber n. 睡眠，微睡 This isn't the only issue. Naps have been linked to conditions such as diabetes, high blood pressure and cardiac problems. However, it's not clear whether these are direct results, or stem from the impact of napping on our sleep habits. (Q3) If you take a nap after about two or three in the afternoon, it's likely to have a negative effect on your ability to get to sleep at night. Breaking your sleep cycle can lead to bad sleeping habits, which themselves become ingrained.cardiac adj. 心脏的 ingrain v. 使根深蒂固 Of course, in the same way that naps can lead to bad sleep, it's also true that bad sleep can lead to wanting to take more naps. (Q4) So, if you find yourself frequently needing to sleep during the day, experts suggest that you consider why that's the case. Are there any potential health issues that could be causing insomnia? Or are work pressure stopping you from getting enough sleep?insomnia n. 失眠 Part III. KEYQ1.【答案】B【解析】细节题。题目出处：It is true that a short nap can help people be more alert, improve their memory and concentration, and reduce risks around tasks with heavy machinery. 意为：“的确，小睡片刻能帮助人们更加清醒，提升记忆力和专注力，还能降低操作重型机械等作业时的风险。” 因此正确答案为B。 Q2.【答案】A【解析】细节题。题目出处：A true power nap should be less than half an hour. 意为：“真正的有效小憩时间应控制在半小时以内。。” 文章明确指出，有效小睡的时间应该少于半小时，超过这个时间可能会导致昏昏沉沉，并抵消小睡的益处，因此正确答案为A。 Q3.【答案】C【解析】细节题。题目出处：If you take a nap after about two or three in the afternoon, it's likely to have a negative effect on your ability to get to sleep at night. Breaking your sleep cycle can lead to bad sleeping habits, which themselves become ingrained. 意为：“如果你在下午两三点之后小睡，很可能会对夜间入睡能力产生负面影响。打乱睡眠周期会导致不良的睡眠习惯，而这些习惯本身又会变得根深蒂固。”因此正确答案为C。 Q4.【答案】B【解析】推理题。题目出处：So, if you find yourself frequently needing to sleep during the day, experts suggest that you consider why that's the case. Are there any potential health issues that could be causing insomnia? Or are work pressures stopping you from getting enough sleep? 意为：“因此，如果你发现自己经常需要在白天睡觉，专家建议你思考原因。是否存在可能导致失眠的潜在健康问题？或者工作压力是否阻碍你获得足够的睡眠？从中可以推断，频繁白天小睡可能表明存在潜在健康问题或压力，因此正确答案为B。 Q5.【答案】D【解析】主旨题。文章主要讨论了小睡的好处和可能引发的问题，包括提高注意力和记忆力的益处，以及可能导致睡眠周期紊乱和健康问题。因此正确答案为D。 （本文图片来源于摄图网，版权归摄图网所有)

To help understand different dialects.B. To become accustomed to faster spoken English.C. To improve grammar skills.D. To focus on vocabulary development.Part II. TRANSCRIPTPractice Your ListeningHello! This week on Ask a Teacher, we answer a question from Zekeriya in Turkiye about listening to English.QuestionDear teacher,When I practice listening, I focus a lot and do a lot of repetitions. (Q1) After a while, I realized that I was actually memorizing the audio recording instead of practicing listening. How do you think I should do an ideal listening exercise?audio adj. 音频的Thank you,ZekeriyaAnswerI’m happy to answer this question, Zekeriya.(Q2) There is not one ideal listening exercise. Instead, there are several good ways to improve your listening.The repetitions you are doing can be necessary and helpful for you to understand what you hear. And repetitions likely help you remember new words and how to pronounce them. But let’s look at more ways you can practice listening. Listening methods(Q3) First, try to find listening material that is just a bit above your ability. This will help you learn new words without making it too difficult for you.It is best to listen to English material that has words written either in captions or in the body text, such as a VOA Learning English article. This will help check your listening.caption n. 字幕You can test yourself by first listening to parts of the audio without reading the words. Note the main ideas and the things you clearly understood. Then, listen to it again and try to understand more details. This is when you can do shorter repetitions. Next, you can check how much you understood by reading the words as you listen to the audio again.TranscribingOne of the best ways to practice listening is by writing every word you hear. This is called transcribing. Even with audio examples as short as one minute, you can learn a lot of English using this method. (Q4) For example, if you are transcribing an interview, you might notice differences between spoken English and written English.transcribe v. 转录，抄写By transcribing, you can notice and learn new expressions, grammar rules and spelling. This method also helps make new words stay in your memory when you read them. That is because you are discovering the answer to a problem you have already tried to solve through listening.Other tips(Q5) Try listening to English spoken at different speeds. Over time, you can follow spoken English at a faster speed. Many videos online let you increase or decrease the speed of playback.Practice listening to English spoken in different foreign accents. This is a useful skill because English is spoken in so many places around the world.accent n. 口音Center your listening on specific sounds or grammatical points. For example, preposition use in English can be difficult. Try listening for prepositions and the words they connect with. This can help you use them correctly in your speaking and writing.Remember that, like any skill, you can improve listening by practicing often and having detailed plans for the methods you will use.For our readers and listeners, what are your questions about American English? We’d like to hear from you. Send us an email at learningenglish@voanews.com. And please include where you are from in your email, too.And that’s Ask a Teacher.Part III. KEYQ1. A. 【解析】细节题。根据：“After a while, I realized that I was actually memorizing the audio recording instead of practicing listening.” 可知Zekeriya主要担心的是自己的练习变成记忆录音，而非练习听力。因此答案是A。Q2. D. 【解析】主旨题。根据：“There is not one ideal listening exercise. Instead, there are several good ways to improve your listening.”可知没有一种完美的听力练习方式。相反，有几种提高听力的好方法。因此答案是D。Q3. B. 【解析】细节题。根据：“First, try to find listening material that is just a bit above your ability.” 可知老师建议尝试难度稍微高于当前能力的听力材料。因此答案是B。Q4.

TRANSCRIPTThe Good Effects of WalkingMany medical experts say that walking is an easy way to improve physical and mental health, support fitness and prevent disease. They advise that walking is a great first step toward a healthy life although other forms of exercise are also important.Good effects of walkingDr. Sarah Eby is a sports medicine physician with Mass General Brigham in the state of Massachusetts. Eby said walking has many good effects and people do not need extra things. (Q1) “You don’t need equipment and you don’t need a gym membership,” Eby noted. “And the benefits are so vast.”The U.S. surgeon general, a federal health officer, recommends that adults get at least two and a half hours of moderate-intensity physical activity every week.Walking helps meet that goal. Exercise lowers the risk of heart disease, high blood pressure, dementia, depression and many kinds of cancer.dementia n. 痴呆，精神错乱Walking also helps blood sugar levels, is good for bone health, and can help people lose weight and sleep better. That is what Julie Schmied said. She is a health care worker with Norton Healthcare in Kentucky, which runs the free Get Healthy Walking Club.Walking is also a relatively low-impact exercise that puts less pressure on joints than other exercises while strengthening the heart and lungs.James Blankenship is 68 years old. (Q2) He said joining a walking club at the Louisville Zoo last year helped him recover after a heart attack and a complex triple-bypass heart operation in 2022.“My cardiologist says I’m doing great,” he said.cardiologist n. 心脏病专家Some say walking is not enough. Anita Gust teaches exercise science at the University of Minnesota Crookston. (Q3) Gust said walking “is not enough for overall health and well-being” because it does not provide resistance training that builds muscle strength and endurance.Some health experts say that is especially important for healthy bone development in women as they age.Experts recommend adding other activities at least twice weekly. These could include using weights, gym equipment or one’s own body for resistance exercises. Training that improves flexibility, like yoga or stretching, can also be helpful.How much should you walk?Many people have heard about the walking goal of 10,000 steps a day. This advice dates back to a 1960s marketing campaign in Japan. But, experts note that this is only a guideline.Shmied said the average American walks about 3,000 to 4,000 steps a day, and it is fine to increase that number to 10,000.(Q4)Setting a time goal can also be useful. Shmied suggests dividing the recommended 150 minutes per week into 30 minutes a day, or 10 minutes three times a day, for five days. During rainy or snowy weather, people can walk in malls or on treadmills.As they become seasoned walkers, they can speed up or walk up hills while still keeping the activity level moderate.“If you can talk but not sing,” Eby said, “that’s what we consider moderate-intensity exercise.”Staying with your walking programWalking with friends, including dogs, is one way to keep walking.Walking clubs have appeared across the nation. (Q5) In 2022, 31-year-old personal trainer Brianna Joye Kohn started City Girls Who Walk with a TikTok post inviting others to walk with her in New York.“We had 250 girls show up,” she said.Since then, the group has walked every Sunday for around 40 minutes, with some meeting afterward for a meal or coffee.The Louisville Zoo launched its walking club in 1987. It joined with Norton Healthcare in 2004 to expand it and now has more than 15,000 registered members. Every day from March 1 through October 31, people walk around and around the zoo before it officially opens.Recently, Janet Rapp walked down a path through the city zoo, waving at friends and stopping briefly to greet big flightless birds called emus that she knows by name.emu n. 鸸鹋（一种大型、不会飞的澳大利亚鸟类）The 71-year-old retiree starts each morning this way with a walking club.“I’m obsessed,” she said. Not only does it ease her joint pain, “it just gives me energy...And then it calms me, too.”obsess v. 着迷，困扰Part III. KEYQ1. C. 【解析】细节题。根据：“You don’t need equipment and you don’t need a gym membership” 可知步行不需要设备，也不需要健身房会员，不需要健身房会员就是步行的好处之一。因此答案是C。Q2. D. 【解析】细节题。根据：“He said joining a walking club at the Louisville Zoo last year helped him recover after a heart attack and a complex triple-bypass heart operation in 2022.” 可知去年加入路易斯维尔动物园的步行俱乐部帮助James在心脏病发作和2022年的复杂三重搭桥手术后康复。因此答案是D。Q3. B. 【解析】细节题。根据：“Gust said walking ‘is not enough for overall health and well-being’ because it does not provide resistance training that builds muscle strength and endurance.”可知Gust提及步行‘不足以维持整体健康和幸福’，因为它不提供能增强肌肉力量和耐力的抗阻训练。因此答案是B。Q4. A. 【解析】主旨题。整个“How much should you walk?”部分讨论了设定步行时间目标的建议，如每天30分钟或每天三次10分钟，表明“Setting a time goal can also be useful”，即设定时间目标是有帮助的。因此答案是A。 Q5. B. 【解析】推理题。根据：“In 2022, 31-year-old personal trainer Brianna Joye Kohn started City Girls Who Walk with a TikTok post inviting others to walk with her in New York.” 可知私人教练Brianna Joye Kohn通过TikTok帖子邀请他人加入她在纽约的步行，创办了City Girls Who Walk，后续还提到大家一起步行后聚餐等，可以看出通过步行能促进社交互动。因此答案是B。（本文图片均来源于网络，仅供学习交流使用，侵删）

第12届教学大赛商务英语组特等奖潘紫萌授课

授课点评：潘紫萌老师在本次大赛中与来自全国各地的商务英语优秀教师展开激烈角逐，在教学理念、教学方法、课堂设计、英语素质、商务知识、教姿教态、师生互动等方面的表现都较突出，最后以总分第一荣获特等奖。潘老师以准确的英语发音先声夺人，丰富的表达方式、适中的语调语速和端庄的教姿教态也令人印象深刻。在课程设计环节，为实现其教学目标，她选择business ethics作为主题，介绍了教学目标、学生特征、以学生为中心和以产出为导向的教学理念，以及线上线下结合、传统和高科技媒体结合等丰富多彩的教学方式。这份介绍全面立体但简明扼要，为后面的演示（demo）课提供了一个很好的支撑。由于大赛的授课时间有限，潘老师突出重点，在演示课上只展示教学方案的第三步，即participatory learning 1 和 post assessment 1。她采用BOPPPS（bridge in, objectives, pre-assessment, participatory learning, post assessment, summary）模型，通过德国大众汽车减排作假、中国支付宝公益植树项目等案例，教学目标涵盖商务英语知识、技能、以及相关的伦理和价值观等。在短短的十几分钟里要达到这么多项教学目标绝非易事。潘老师通过一系列的短视频、多种教学方法（如听力填空、案例讨论、汉译英、样本对话补正等）以及活泼的师生互动，较好地实现了教学目标，显示出选手突出的课堂组织能力。商务英语教学起源于英美等国，因此基本使用本国素材、讲本国故事。传入中国后，主要使用外国素材、讲外国故事。令人欣喜的是，潘老师注意突出中国特色，多次引用中国案例，讲授中国故事，传播中国价值观。加上她出色的英语基本功和良好的师生互动，使得教学过程十分流畅，也没有不同文化同场展示的违和感。总而言之，潘紫萌老师在授课环节的各方面表现都很优秀。不足之处当然也有。首先， 8’13’’开始的讨论过于仓促，只有18秒， 8’31’’就结束了。由于讨论不充分，在随后的问答环节中，更多的回答似乎来自老师而不是学生。第二个是要增加教学过程的自然自发 (spontaneity)。不知是因为课前多次排练还是老师特意要求，学生的产出只有一次对话（17’40’’）相对自然，其他的多次回答虽准确无误，但都像中国小学生朗读课文或回答问题，语音、语调、语速都过于整齐合一，这不利于培养学生的英语实际表达能力。点评专家：陈准民
