我们需要一个好的睡眠英语作文初一全文共5篇示例，供读者参考篇1Why We Need Good SleepHi there! My name is Alex and I'm in 5th grade. Today I want to talk to you about something that is super important for kids like us - getting good sleep! Sleep might not seem like a big deal, but trust me, it really is. Let me tell you why.First of all, when we don't get enough sleep, we feel grumpy and tired all day long. Have you ever had one of those days where you just can't focus and everything seems hard? That's what happens when you're sleep deprived. Your brain gets all foggy and it's really difficult to learn new things or remember what you've already learned. No one wants to be a zombie at school!Lack of sleep can also make you more likely to get sick. Our bodies need sleep to stay strong and fight off illnesses. When we're well-rested, our immune systems work properly to protect us from nasty germs. But if we're not getting enough ZZZs, we'remore vulnerable to catching colds, flus, and other sicknesses. No fun!Sleep is also crucial for growth and development. Whilewe're snoozing away, our bodies release hormones that help us grow taller and stronger. If we don't get sufficient sleep over long periods of time, it can negatively impact our growth and development. As kids, we're still growing a ton, so we need plenty of high-quality sleep.You know how your parents are always telling you to get some exercise and play outside? Well, sleep is just as important for being physically active and performing well in sports or activities. When you're well-rested, you have more energy, coordination, and stamina. Athletes who don't get adequate sleep are more likely to feel fatigued and perform poorly. Even during a simple game of tag at recess, lack of sleep can impact your abilities.Okay, so now that we know why sleep is the BEST, what can we do to make sure we're getting enough high-quality rest? Here are some of my top tips:Have a soothing bedtime routineDoing the same relaxing things each night before bed helps signal to your body that it's time to wind down. Things like taking a warm bath, reading a book, or listening to calm music can be very soothing.Keep electronics out of the bedroomThe blue light from TVs, phones, and tablets can trick our brains into thinking it's daytime. It's best to avoid screen time for at least an hour before bedtime.Make your sleep environment comfy and cozyA dark, cool, and quiet bedroom is ideal for good sleep. Maybe you can hang some blackout curtains, use a fan, or invest in a good quality mattress and pillows.Be consistent with bedtimeHaving a set bedtime and wake time helps regulate your body's internal clock. Even on weekends, it's best not to stray too far from your regular schedule.Get plenty of exercise and time outdoorsBeing physically active during the day and getting exposure to natural light helps you sleep more soundly at night. Just be sure not to have any super energetic playtime right before bed!Avoid stuff with caffeineThings like soda, chocolate, and even some medications can contain caffeine which is a stimulant. It's best to avoid it in the late afternoon and evening hours.So there you have it, friends! Getting enough quality sleep is one of the healthiest things we can do for our minds and bodies. It helps us learn, grow, fight off sickness, and just feel our overall best. Let's all try to be sleep champs from now on! Nighty night.篇2We Need Good SleepHey there friends! Today I want to talk to you about something that's super important for all of us - getting good sleep. I know, I know, you're probably thinking "Sleep is so boring! Why does he want to talk about that?" But trust me, getting enough good quality sleep is actually really cool and can help us out in so many ways.First off, let me just say that not getting enough sleep is a total bummer. When I don't get my zzz's, I feel grumpy, have no energy, and can't concentrate on anything. It's like my brain turns to mush! And we all know it's hard enough to pay attention in class without a mush brain. Studies show that not gettingenough sleep can make it way harder to learn new things and remember what you've already learned. So if you want to be a brainiac, you gotta catch those winks!Lack of sleep doesn't just affect our smarts though. It can also make us feel really yucky physically. Have you ever gotten sick after not sleeping well for a few nights? That's because sleep is crazy important for keeping our immune systems in tip-top shape to fight off illness. When we're sleep deprived, we're much more likely to catch every cough, sniffle and sneeze that comes our way. No thank you! I don't know about you, but I want to be healthy so I can run around with my friends, not stuck at home with the flu.Speaking of activities, achieving our goals and dreams requires energy and alertness - two things you'll be seriously lacking without good sleep. Want to become a basketball star? Soccer pro? You'll need plenty of sleep to be able to run fast, have quick reflexes, and perform at your absolute best. Even if sports aren't your thing, hobbies like gaming, art, music and more all require mental focus and physical stamina that suffer big time when you're running on empty from no sleep.Okay, okay...you get it - sleep is important. But how much sleep do we really need? The experts recommend that kids ourage (yeah, I'm talking to you middle schoolers!) get between9-12 hours per night. I know that seems like a ridiculous amount of sleep, but think about how much energy we use throughout the day learning, playing, and just being awesome. We need a huge chunk of sleep to recharge our batteries!Now the tricky part - actually getting quality sleep when there are so many things competing for our attention. From homework to video games, Instagram to YouTube, it's easy to get carried away and sacrifice sleep. But we have to be disciplined about our sleep routines!Here are some of my tips for ensuring you get your beauty rest:Set a bedtime and stick to it every single night, even on weekends. Our bodies crave consistency.Power down electronics at least an hour before bedtime. The blue light messes with our natural sleep cycles.Create a relaxing pre-bed routine like reading, taking a bath, or doing some light stretches. This signals to your body that it's time to wind down.Make sure your sleep environment is cool, dark and quiet. Maybe use a fan, blackout curtains or a white noise machine.Save your bed for sleep only. Don't watch TV, play games or do homework there. Your brain will associate the bed with those activities instead of sleepy time.Be active and get outside during the day. This helps you feel more tired at night.Avoid consuming caffeine, big meals or sugary snacks too close to bedtime.If you still have trouble sleeping despite your best efforts, don't freak out! Sometimes our bodies just need a little extra help. Talk to your parents or doctor about safe sleep supplements or techniques like meditation that can help.Getting enough good quality sleep every single night is one of the absolute best things you can do for your health, happiness and success as you're growing up. An well-rested body and mind will help you kill it in the classroom, crush it on the field, and just make the most out of every single day. So let's all make sleep a priority - our future selves will thank us!Now if you'll excuse me, I need to go practice what I preach and get my beauty sleep. Sleep tight, my friends!篇3My Awesome Sleep and Why It's ImportantHi there! My name is Tommy and I'm 10 years old. Today I want to tell you all about sleep because it's one of the most amazing things ever! Getting good sleep is super important for kids like me.First of all, sleep helps me grow big and strong. When I'm asleep, my body releases something called growth hormones that help me get taller and build muscle. It's like magic! If I don't get enough sleep, those growth hormones don't work as well. That's why kids who don't sleep enough can end up being short or skinny. I want to be a big, strong grown-up, so I make sure to get my sleep.Sleep also gives my brain a chance to recharge its batteries. During the day, my brain works really hard at school, learning new things and solving problems. But at night when I'm sleeping, my brain gets to rest. It sorts through all the new information I learned that day and locks it into my memory. Cool, right? That's why if I stay up too late, I have a hard time paying attention and remembering things the next day at school.Another awesome thing about sleep is that it keeps me healthy. When I'm sleeping, my body produces proteins that help fight off sicknesses like colds and flu. It's like my ownpersonal army of germ fighters! Sleep also reduces inflammation, which means I recover faster if I get an ouchie or pull a muscle. Who knew sleep could be such a great doctor?But sleep doesn't just help my body, it also keeps my mind happy. You know how you can feel really grumpy and upset over small things when you're tired? That's because sleep boosts your mood. It gives your brain chemicals called neurotransmitters that reduce stress and make you feel calm and content. With enough sleep, I wake up feeling refreshed and ready to conquer the day!Getting quality sleep can even help me learn better in school. Studies show that kids who get sufficient sleep have better focus, faster reflexes, and are more creative. During sleep, my brain practices skills I learned that day and makes new connections between ideas. It's like my brain is studying while I'm dreaming about scoring the winning goal or flying on a magic carpet!I try to get about 9-12 hours of sleep every night to keep my mind and body in top shape. It's not always easy because there's so much fun stuff to do, like playing video games or watching movies. But my parents are really firm about my bedtime routine. We have a special schedule where I take a warm bath, brush my teeth, read a book, and then lights out by 8:30pm. Sometimes I'llbeg for "just one more episode!" but my mom always says "You can watch more tomorrow after you've recharged your battery."Even on weekends, my parents don't let me sleep in too late or take crazy long naps during the day. They explain that keeping a regular sleep schedule is best so my body's internal clock stays on track. I may not always like it, but I know they're just looking out for me.Getting enough sleep can be a challenge with how busy kids' lives are nowadays with homework, activities, screen time, and more. But it's so worth it! When I get my zzz's, I've got way more energy to run around and play, I hardly ever feel stressed, and I'm a rock star at staying focused in class. My parents say I'll appreciate those good sleep habits even more when I'm a teenager and young adult.So there you have it, the awesome power of sleep! I'm actually getting a little sleepy just talking about it. Time for me to snuggle up in my Superman pajamas and dream of flying high. Sleep tight, everyone!篇4We Need Good SleepHi everyone! My name is Jamie and I'm 10 years old. Today I want to talk to you about why getting good sleep is super important, especially for kids like us.First of all, sleep helps our bodies and brains grow properly. When we're sleeping, our bodies make hormones that help us grow taller and stronger. Our brains also sort through everything we learned during the day and build connections that help us remember stuff better. Isn't that cool? It's like our brain is a busy little worker at night, organizing our memories!Speaking of memories, have you ever had a hard time paying attention in class after not getting enough sleep? I sure have! When I'm tired, my brain feels foggy and I can't focus as well on what my teacher is saying. Getting enough quality sleep helps keep our brains sharp so we can soak up all those facts and lessons.Sleep also affects our moods and behavior. Have you noticed how cranky and grumpy you feel when you're really tired? Yeah, me too! Not getting proper rest makes it harder to control our emotions and we're more likely to feel mad, sad or frustrated about little things. But when I get my zzzs, I wake up feeling happy, patient and ready to be my best self.Did you know sleep is important for physical health too? When we sleep well, it helps keep our immune systems strong so we don't get sick as easily. It's also good for our muscles and injuries can heal faster. Pro athletes know how crucial sleep is for performing their best! Maybe that's why my soccer coach is always nagging us to get to bed early before games.But how much sleep do kids really need? Doctors say elementary school kids like us should get between 9-12 hours of sleep per night. That's a lot compared to grown-ups, huh? Our bodies and brains are just working extra hard to develop properly during these years.Of course, that doesn't mean we can just sleep alllll day either. We need a good balance of sleep time and awake time for learning, playing, and spending time with family and friends too. Moderation is key, just like with anything!So what can we do to improve our sleep? Here are some of my top tips:Stick to a routine bed and wake-up time, even on weekends. Our bodies love predictable schedules.Create a calming bedtime ritual like taking a warm bath, reading stories, or listening to relaxing music. It signals to our brains that it's time to wind down.Avoid screens like TVs, computers and phones for at least an hour before bedtime. The blue light exposure can trick our brains into thinking it's daytime.Make sure your bedroom is cool, dark and quiet. Maybe use a fan, blackout curtains or a white noise machine.Do some light stretching or deep breathing exercises ifyou're having trouble falling asleep. It helps relax both the body and mind.If you're still wide awake after 20 minutes of trying to sleep, get up and do a quiet activity like coloring or reading until you feel sleepy again.Those are just a few ideas, but I'm sure your parents or doctor can share even more good tips. The most important thing is making sleep a real priority, just like eating healthy foods and exercising regularly.I know getting enough rest can be a struggle sometimes, like when we're feeling excited or nervous about something comingup. But taking care of our sleep needs will pay off big time by keeping us healthy, smart and happy! Who doesn't want that?So tonight, I challenge you to be a sleep champion! Get ready for dream land a little earlier than usual, and see if you wake up feeling like a total rock star tomorrow. I'm going to give it a try too, because we all need (and deserve!) quality zzzzs. Sleep tight, friends!篇5We Need Good SleepHi there! My name is Sammy and I'm 10 years old. Today I want to talk to you about something that is super important for kids like us - getting good sleep! Sleep might not seem that exciting, but trust me, it's really really important.You know how sometimes you feel grumpy or have a hard time paying attention in class? That's often because you didn't get enough sleep the night before. When we don't get good sleep, our bodies and brains don't work as well as they should. It's like trying to run a race on an empty stomach - you just don't have the energy!So why is sleep so important? Well, there are lots of reasons! When we sleep, our bodies get a chance to rest and recharge. It'slike putting new batteries in a toy that's running out of power. Sleep gives our bodies the energy we need to grow, heal, and fight off sickness. Our brains also need sleep to function properly. You know that feeling when you can't think clearly or you forget things easily? That's your brain telling you it needs more sleep!During sleep, our brains also sort through all the information and experiences we had during the day. It's like a little file clerk organizing everything in our brain's filing cabinets. Pretty cool, right? When we don't get enough sleep, our brains can't do this important job properly, which makes it harder for us to learn and remember things.Sleep is also really important for our moods and emotions. Have you ever noticed that when you're tired, you get cranky or upset more easily? That's because lack of sleep can make us feel more irritable, sad, or anxious. On the other hand, when we get enough good sleep, we tend to feel happier, calmer, and more patient.So how much sleep do we need? Well, that depends on our age, but for kids around my age (10 years old), experts recommend getting between 9 and 12 hours of sleep every night. That might sound like a lot, but remember, we're still growing and our bodies and brains need that extra rest.Getting good sleep isn't always easy, though. Sometimes we stay up too late watching TV, playing video games, or just goofing around. Sometimes we have troubles falling asleep or we wake up a lot during the night. That's why it's important to have good sleep habits, or what grown-ups call "sleep hygiene."Here are some tips for getting better sleep:Stick to a regular sleep schedule, even on weekends. Our bodies like routine!Create a calming bedtime routine, like taking a warm bath, reading a book, or listening to soft music.Make sure your bedroom is cool, dark, and quiet – just the way our bodies like it for sleeping.Avoid screen time (TV, phones, tablets) for at least an hour before bedtime. The blue light from screens can mess up our sleep patterns.Get plenty of exercise and activity during the day (but not too close to bedtime).Avoid caffeine (found in sodas, chocolate, and some teas) in the afternoon and evening.If you're having trouble sleeping, don't stay in bed awake. Get up and do something relaxing until you feel sleepy again.If you follow these tips, you'll be well on your way to becoming a sleep champion!Good sleep is so important for our health, our happiness, our ability to learn and grow, and just feeling our best every day. So let's all make sleep a priority, okay? Trust me, your body and brain will thank you for it!So there you have it – everything you need to know about why sleep is awesome and how to get more of it. Get those zzz's, my friends! And remember, a well-rested kid is a happy, healthy, and successful kid.。

睡眠英语演讲稿1 According to a survey, we know most middle school students sleep less than 7 hours each night, much less than required. First of all, the students have too much homework. Second, schools and parents pay less attention to their sleep. Another important reason is that many students play with their cell phones or iPads before sleeping. This is one of the main reasons for bad sleep. Other reasons include stress and bad moods. So we must take some ways to stop this. First, less homework should be given to the students by teachers and parents. Second, students need to keep away from digital devices for at least an hour before sleep .Last, more attention should be paid to their health. 根据⼀项调查，我们知道⼤多数中学⽣每晚睡不到7个⼩时，远远少于所需。

TED--一定要睡个好觉（英文）Sleep, it’s something we spend about a third of our lives doing, but do any of us really understand what it’s all about? Two thousand years ago, Galan, one of the most prominent medical researchers of the ancient world, proposed that while we‘re awake, our brain’s motive force, it’s juice, would flow out to all the other parts of the body, animating them but leaving the brain all dried up, and he thought when we sleep, all this moisture that filled the rest of the body would come rushing back, rehydrating the brain and refreshing the mind.Now, that sounds completely ridiculous to us now, but Galan was simply trying to explain something about sleep that we are deal with every day. See, we all know based on our own experience that when you sleep, it clears your mind, and when you don’t sleep, it leaves your mind murky. But while we know a great deal more about sleep now than when Galen was around, we still haven’t understood why it’s that sleep, of all of our activities, has this incredible restorative function for the mind. So today I want to tell you about some recent research that may shed new light on this question.We fund that sleep my actually be a kind of elegant design solution to some of the brain’s most basic needs, a unique way that the brain meets the high demands and the narrow margins that set it apart from all the other organs of the body. So almost all the biology that we observe can be thought of as a series of problems and their corresponding solutions, and first problemthat every organ must solve is a continuous supply of the nutrients to fuel all those cells of the body. In the brain, that is especially critical; its intense electrical activity uses up a quarter of the body’s entire energy supply, even though the brain accounts for only about two percent of the body’s mass. So the circulatory system solves the nutrient delivery problem by sending blood vessels to supply nutrients and oxygen to every corner of our body. You actually see it in this video here. Here, we’re imaging blood vessels in the brain of a living mouse. The blood vessel form a complex network that feels the entire brain volume. They start at the surface of the brain, and then they dive down into the issue itself, and as they spread out, they supply nutrients and oxygen to each and every cells in the brain.Now, just as every cell requires nutrients to fuel it, every cell also produces waste as a byproduct, and the clearance of that waste is the second basic problem that each organ has to solve. This diagram shows the body’s lymphatic system, which has involved to meet this need. It‘s a second parallel network of vessels that extend throughout the body. It takes up proteins and other waste from the spaces between the cells, it collects them, and then dumps them into the blood so they can be disposed of.But if you look really closed at this diagram, you’ll see something that doesn’t make a lot sense. So if we were to zoom into this g uy’s head, one of the things that you would see there is that there are no lymphatic vessels in the brain. But that doesn’t make a lot of sense, does it? I mean, the brain is this intensely active organ that produces a correspondingly large amount of waste that must be efficiently cleared. And yet, it lackslymphatic vessels, which means that the approach that takes to clearing away its waste won’t work in the brain. So how, then, does the brain solve its waste clearance problem? Well, that seemingly mundane question is where our group first jumped into this story, and what we found as we dove down into the brain, down among the neurons and the blood vessels, was that the brain’ s solution to the problem of the waste clearance, it was really unexpected. It was ingenious, but it was also beautiful.Let me tell you about what we found. So the brain has this large pool of clean, clear fluid called cerebrospinal fluid. We call it the CSF. The CSF fills the space that surrounds the brain, and wastes from inside the brain make their way out to the CSF, which gets dumped, along with the waste into the blood. So in that way, it sounds a lot like the lymphatic system, doesn’t it? But what’s interesting is that the fluid and the waste from inside the brain, they don’t just percolate their way randomly out to these pools of the CSF. Instead, there is a specialized network of plumbing that organizes and facilities this process.You can see that in these videos. Here, we‘re again imaging into the brain of living mice. The frame on your left shows what’s happening at the brain’s surface, and the frame on your right shows what’s happening down below the surface of the brain within the tissue itself. We’ve labeled the blood vessels in red, and the CSF that’s surrounding the b rain will be green. Now, what was surprising to us was that the fluid on the outside of the brain, it didn’t stay on the outside. Instead, the CSF was pumped back into and through the brain along the outsides of the blood vessels, and as it flushed down into the brain along the outsidesof these vessels, it was actually helping to clear away, to clean the waste from the spaces between the brain’s cells. If you think about it, using the outsides of these blood vessels like this is a really clever design solution, because the brain is enclosed in a rigid skull and it’s packed full of cells, so there is no extra space inside it for a whole second set of vessels like the lymphatic system. Yet the blood vessels, they extend from the surface of the brain down to reach every single cell in the brain, which means that fluid that‘s traveling along the outsides of these vessels can gain easy access to the entire brain’s volume, so it’s actually this really clever way to repurpose one set of vessels, the blood vessels, to take over and replace the function of a second set of vessels, the lymphatic vessels, to make it so you don’t need them.And what’s amazing is that no other organ takes quiet this approach to clearing away the waste from between its cells. This is a solution that is entirely unique to the brain. But our most surprising finding was that all of this, everything I just told you about, with all this fluid rushing through the brain, it’s only happening in the sleeping brain. Here, the video on the left shows how much of the CSF is moving through the brain of a living mouse while it’s awake. It’s almost nothing. Yet in the same animal, if we just wait just a little while until it’s gone to sleep, what we see is that the CSF is rushing through the brain, and we discovered that at the same time when the brain goes to sleep, the brain cells themselves seem to shrink, opening up spaces in between them, allowing fluid to rush through and allowing waste to be cleared out.So it seems that Galen may actually have been sort of the right track when he wrote about fluid rushing through the brain when sleep came on. Our own research, now it’s 2000 years later, suggesting that what’s happening is that when the brain is awake and is at its most busy, it puts off clearing away the waste from the spaces between its cells until later, and then, when it goes to sleep and doesn’t have to be as busy, it shifts into a kind of clearing mode to clean away the waste from the spaces between it cells, the waste that’s accumulated thro ughout the day. So it’s actually a little bit like how you or I, we put off our household chores during the work week when we don’t have time to get to do it, and then we play catch up on all the cleaning that we have to do when the weekends rolls around.Now, I’ve just talked a lot about waste clearance, but I haven’t been very specific about the kinds of waste that the brain needs to be clearing during sleep in order to stay healthy. The waste product that these recent studies focused most on is amyloid-beta, which is a protein that’s made in the brain all the time. My brain’s making amyloid-beta right now, and so is yours. But in patients with Alzheimer’s disease, amyloid-beta builds up and aggregates in the spaces between the brain’s cells, instead of b eing cleared away like it’s supposed to be, and it’s this buildup of amyloid-beta that’s thought to be one of the key steps in the development of that terrible disease. So we measured how fast amyloid-beta is cleared from the brain when it’s awake versus when it’s asleep, and we found that indeed, the clearance of amyloid-beta is much more rapid from the sleeping brain. So if sleep, then, is part of the brain’s solution to the problem of the waste clearance, then this may dramaticallychange how we think about the relationship between sleep, amyloid-beta, and Alzheimer’ s disease.A series of recent clinical studies suggest that among patients who haven’t yet developed Alzheimer’s disease, worsening sleep quality and sleep duration are associated with a greater amount of amyloid-beta building up in the brain, and while it’s important to point out that these studies don’t prove that lack of sleep or poor sleep cause Alzheimer’s disease, they do suggest that the failure of the brain to keep its house clean by clearing away waste like amyloid-beta may contribute to the development of conditions like the Alzheimer’s. So what this new research tell us, then, is that the one thing that all of you already knew about sleep, that even Galen understood about sleep, that it refreshes and clears the mind, may actually be a big part of what sleep is all about.See, you and I, we go to sleep every single night, but our brains, they never rest. While our body is still and our mind is off walking in dreams somewhere, the elegant machinery of the brain is quietly hard at work cleaning and maintaining this unimaginably complex machine. Like our house work, it’s a dirty and thankless job, but it’s also important. In your house if you stop cleaning your kitchen for a month, your home will become completely unlivable very quickly. But in the brain, the consequences of falling behind may be much greater than the embarrassment of dirty countertops, because when it comes to cleaning the brain, it is the very health and function of the mind and the body that’s at stake, which is why understanding these very basic housekeeping functions of the brain today may becritical for preventing and treating disease of the mind tomorrow.Thank you.。

关注睡眠广播稿范文英文回答：Sleep is an essential part of our daily lives. It isnot only a time for our bodies to rest and rejuvenate, but also a crucial period for our brains to process information and consolidate memories. As someone who has always struggled with sleep, I have come to realize the importance of establishing a healthy sleep routine.One of the main benefits of a good night's sleep is improved cognitive function. When we sleep, our brains go through different stages of sleep, including REM (rapid eye movement) sleep, which is associated with dreaming and memory consolidation. During REM sleep, our brains process and organize the information we have learned during the day, making it easier for us to recall and retain information. Without enough sleep, our cognitive abilities, such as attention, concentration, and problem-solving skills, canbe significantly impaired.Another advantage of sufficient sleep is better physical health. Lack of sleep has been linked to a variety of health problems, including obesity, diabetes, heart disease, and weakened immune system. When we are sleep deprived, our bodies produce more ghrelin, a hormone that stimulates appetite, and less leptin, a hormone that suppresses appetite. This imbalance can lead to overeating and weight gain. Moreover, chronic sleep deprivation can increase the risk of developing chronic conditions, such as diabetes and heart disease.Furthermore, sleep plays a crucial role in our emotional well-being. When we are sleep deprived, we are more likely to experience mood swings, irritability, and increased stress levels. Lack of sleep can also contribute to the development of mental health disorders, such as depression and anxiety. On the other hand, getting enough sleep can help regulate our emotions and improve ouroverall mood.To establish a healthy sleep routine, there are severalstrategies that I have found helpful. First, it is important to set a consistent sleep schedule by going to bed and waking up at the same time every day, even on weekends. This helps regulate our body's internal clock and promotes better sleep quality. Second, creating a relaxing bedtime routine can signal to our bodies that it is time to wind down. This can include activities such as reading a book, taking a warm bath, or practicing relaxation techniques like deep breathing or meditation. Finally, itis important to create a sleep-friendly environment by keeping the bedroom dark, quiet, and cool.中文回答：睡眠是我们日常生活中不可或缺的一部分。

TED英语演讲稿：我们为什么要睡觉Ladies and gentlemen,Today I would like to talk to you about something that we all do every day. It is something that we often take for granted, yet it is essential for our health and well-being. I am talking about sleep.Sleep is something that we all need, yet not all of us get enough of it. In today's society, we often prioritize other things over sleep, such as work, socializing, and entertainment. We think that we can function just fine on a few hours of sleep, but the reality is that we cannot. Our bodies need sleep to function properly, both physically and mentally.So why do we need sleep? The answer to that question is complex, but several factors come into play.The first factor is rest and restoration. When we sleep, our bodies get a chance to repair and restore themselves. Our muscles and tissues repair themselves, and we produce hormones that support growth and development. Without enough sleep, our bodies cannot perform these vital functions.The second factor is cognitive function. Sleep is essential for our brain function. When we sleep, our brains consolidate and process information that we learned during the day. This helps us to remember important things and learn new skills. Lack of sleep can lead to problems with memory, learning, and concentration.The third factor is emotional health. Sleep is necessary foremotional well-being. When we sleep, our brains process and regulate our emotions. Lack of sleep can lead to problems with emotional regulation, such as depression, anxiety, and irritability.Now that we know why we need sleep let's talk about how much sleep we actually need. The answer to that question varies depending on age, lifestyle, and individual needs. However, the general recommendation for adults is 7-9 hours of sleep per night. Children and teenagers may need more sleep, while older adults may need less.It is also important to note that the quality of our sleep is just as important as the quantity of our sleep. We need to ensure that we are getting enough deep sleep, which is the stage of sleep that is most restorative and beneficial for our bodies and minds.So what can we do to ensure that we are getting enough high-quality sleep? Here are a few tips:- Establish a bedtime routine and stick to it, even on weekends.- Create a sleep-conducive environment, which means eliminating noise, light, and distractions in the bedroom.- Avoid caffeine, alcohol, and heavy meals before bedtime.- Exercise regularly, but not too close to bedtime.- Practice relaxation techniques, such as deep breathing or meditation, to help you fall asleep.In conclusion, sleep is not a luxury; it is a necessity. We need sleep to function at our best physically and mentally. So let's make surethat we are prioritizing our sleep and giving our bodies the rest and restoration that they need. Thank you.。

Many of them even begin to stay up studying. A heated discussion was held to argue about the advantages and disadvantages of it.Some students have their own reasons for studying late into night. Firstly, the quietness in the night will result in better effectiveness. Besides,the examinations are only 200 days away so its high time they made good use of every minute. What’s more, seeing others studying so hard, they will feel anxious if they don’t take action.Some others, however, hold the opposite view, saying that a sensible senior student must know how to balance his time between study and leisure. As everyone knows, staying up late will naturally affect the next days performance in class.As far as I’m concerned, different people have different habits. If you can hold it, it’s your own business when to study and when to sleep.与睡眠有关的英语演讲稿2Many people want to ask, what is the best time for sleep? Do we need to sleep early or late? My opinion is to sleep early. Here is the reason why we should sleep early. First, it will make you more healthy. Sleep late would cause illness, long time not sleeping early will damage your body. Second, many people had said that if you dont get many time to sleep, and you sleep late would make black rim of the eye. That is not healthy also, and its not beautiful. We should give our body a rest. Sleep is the best way. Well, there are certain time that is best for us to sleep. Sleep early is definitely better than sleep late. Also, we should not keep awake the whole night. You dont feel the damage when you are young, but when you get older, the problem start to appear. Many disease of heart and lung started from not sleep at night. Many youth think it is fun tokeep awake or sleep late. But I dont think so. Keep your body healthy. I strongly suggest to sleep early.与睡眠有关的英语演讲稿3Staying up late will be detrimental to human health, because the adrenal cortex hormone and growth hormone are all secreted during the night when people are sleeping. The former is secreted before dawn, which can promote the metabolism of carbohydrate in human body, and protect the development of muscle; while the latter is produced only after sleep, which can not only promote the growth and development of young people, but also can delay the aging process of the elderly. As a result, staying up late will cause a variety of harms to human body. First, frequent fatigue and decreased immunityThe most serious sequence caused by staying up late is fatigue and lack of energy. Whats more, the immunity of human body will decrease accordingly. And some other symptoms such as cold, gastrointestinal infections, allergies will also appear.Second, headacheThe next day after staying up late, you will suffer from headache when you are at work or at class. You will be unable to concentrate. Whats more, long-term staying up late and insomnia will also bring invisible damage to our memory.Third, dark circles and puffinessNight is the time for human body to have a good rest. Without adequate rest, you will feel extremely tired, which will lead to poor blood circulation around the eyes, causing dark circles or blood streak in the white of the eye.Fourth, dry skin, dark spots and acneThe period between 11:00 pm to 3:00 am in the next day is the beauty time, and it is also the time for the meridians in human body to move to gall bladder and liver. If these two organs do not have adequate rest, it will be reflected on the skin. So some problems such as roughness, yellowish face, dark spots and acne will appear. Whats worse, long-term staying up late will slowly cause some neurological and psychiatric symptoms such as insomnia, forgetfulness, irritability, anxiety and so on. Fifth, affecting fertilityFor the men and women of childbearing age, if they always stay up late, it will not only affect the motility and quantity of male sperm, but also will affect the secretion of female hormone and the quality of ovum, and it is also likely to influence the menstrual cycle.Sixth, increasing the probability of getting some chronic diseases People who staying up all night always have higher secretion of adrenaline than the average person, which will increase the pressure on metabolism, and thus leading to some chronic diseases, such as hypertension and diabetes.Whats more, there are also other harms caused by staying up late, such as poor eyesight or dysfunction of the liver. We should pay special attention to these bad effects, and try not to stay up late at night.与睡眠有关的英语演讲稿4Today more and more students are inclined to stay up at night.They enjoy the night so much that they dont go to bed until deep into the night or even until the next morning.Hower that would do harm to their health.Students who usually stay up can get tired the next day and they often sleep in class.They cant listen to the teachers heart and soul.As time goes on,they will do bad in their study ,and will be poor health.For these reasons,I would like to advise those students who are staying up not to do that again!You should go to bed before 11 in the evening.Will you take my advice?与睡眠有关的英语演讲稿5Do you always work or study until midnight?Do you often hang out or spend much time in pubs at late night?If you answered yes to either of these questions, you are unfortunately one of the large groups of people who always stay up late. Because of the fierce competition in the society, it seems that everyone has endless work to do and twenty-four hours per day is not enough. Therefore, an increasing number of people stay up late in order to finish the mountainous work. Besides, lots of young people enjoy entertainingat late night. However, many of them are still not aware of the bad effects of staying up late. In fact, it does severe harm to us in three aspects, namely physical health, work efficiency and mental stress.In the first place, staying up late badly impacts on our physical health condition. The human adrenal cortex hormone and growth hormone, which are vital substances for human body, only secrete at night. The former secretes before the dawn facilitating the carbohydrate metabolism and protecting the development of muscle function. The latter only secretes after sleeping. It can improve the growth of the young and slow down the aging of the elderly. However, if people often stay up late, the secretion of these two substances will be gravely impacted. Finally, our health condition will be degraded. It can cause a variety of harms to human body. Normally, frequent staying up late will lead to fatigue and degraded immunity. People may easily get sick when the weather gets a little bit colder or hotter. In addition, it can also cause headache. People may feel heavy in the brain and dizzy for a whole day. Besides, the fertility of both male and female will be impacted. For women, it will affect the secretion of female hormones and the quality of ova. It also tends to affect the menstrual cycle. For men, both the quality and quantity of sperm will be impacted. What is more, staying up late can also damage people’s eyesight, skin and memory capacity, and cause black eyes as well.Furthermore, it negatively impacts on the work efficiency. On the one hand, owing to the discomfort of your health as mentioned above, you may feel distracted from the work. On the other hand, because of the decrease of the memory capacity, your work efficiency will be lower, which means that you may not complete the things as you want. Assume that you are a university student and you plan to review for your psychology examination next week after tomorrow’s class. Nevertheless, you stayed up late yesterday for some reason. Therefore, you probably be late for tomorrow’s class or even skip it. Thus, you must find other time to compensate for it. Afterwards, when preparing your examination, you may feel headache and cannot concentrate on it, thus having difficulty memorizing and understanding the psychological terms and principles. Therefore, your schedule for reviewing chapter 2 and chapter3 will be changed. You can only review chapter 2 and may not finish chapter 3. However, in order to finish reviewing on time, you are more than likely to stay up late again. Then, you will be in the vicious cycle and your work efficiency will be lower and lower.What is also noticeable is that staying up late can bring about mental stress. Since your work efficiency is lower, you probably doubt yourself whether you are a capable person or not. You may think you are not so smart as others and even fear yourself that you can hardly get a good grade in your psychology examination, which makes you feel moreanxious and upset. Besides, if you frequently stay up late, you definitely look tired and in low spirits. Therefore, when working on a group project, maybe nobody wants to be in the same group with you, a low-efficient and anxious person. Thus, you will feel separated from others, which possibly makes you more stressed and upset.In conclusion, although we have a lot of work to do and various activities to participate in, staying up late is by no means a good choice for us. It badly impacts on our physical health, lowers our work efficiency and makes us stressed and anxious. Faced with too much work, we should make good arrangements in advance and maintain a healthy lifestyle.与睡眠有关的英语演讲稿。

英语演讲稿《早睡的好处》（优秀范文五篇）第一篇：英语演讲稿《早睡的好处》Good morning everyone, I’m so happy to give you a warming speech about “going to bed early”in such a cold/sunny/rainy day.Before starting this topic, I want to ask you a question: which period of time means going to bed early? Well, the answer is very simple, nine PM to eleven point.Next, I want to tell you three benefits about sleeping early.Now, I will make my first point: Sleeping early helps metabolism.Our body needs to send away all the unwanted waste from within.For example, nine PM to eleven point is liver detoxification time.The second point is going to bed helps positive performance.Sleeping continuously for at least 7 hours in the night is necessary.Inadequate sleep will curb your ability to think creatively, cope up with stress and concentrate.All these stress factors will have a negative impact on your performance.Thirdly, sleeping up early protects you from diseases.By sleeping late in the night you are only stressing yourself which will increase the blood pressure and cholesterol levels.This routine can affect you with cancer and heart diseases for life.By the end, let’s review the benefits of going to bed early.The first ,helpsmetabolism ,the second helps positive performance and the third one is sleeping early protects you from diseases.I wish all of you sit here will start going to bed early from tonight.Thank you!第二篇：学英语的好处 (演讲稿)As everyone knows,English is very important today.It has been usedeverywhere in the world.It has become the most common language on Internet and for international trade.If we can speakEnglish well,we will have more chance to succeed.Because more and more people have taken notice of it,the number of the people who go to learn English has increased at a high speed.But for myself,I learn English not only because of its importance and itsusefulness,but also because of my love for it.When I learn English, I can feel a different way of thinking which gives me more room to touch the world.When I read English novels,I can feel the pleasure from the book which is different from reading the translation.When I speak English, I can feel the confident from my words.When I write English,I can see the beauty which is not the same as our Chinese...I love English,it gives me a colorful dream.I hope I can travel around the world one day.With my good English, I can make friends with many people from different contries.I can see many places of great intrests.I dream that I can go to London,because it is the birth place of English.I also want to use my good English to introduce our great places to the English spoken people,I hope that they can love our country like us.I know, Rome was not built in a day.I believe that after continuous hard study, one day I can speak English very well.If you want to be loved, you should learn to love and be lovable.So I believe as I love English everyday , it will love me too.I am sure that I will realize my dream one day!Thank you!正如每个人所知，英语在今天十分重要。

00:11Sleep. It's something we spend about a third of our lives doing, but do any of us really understand what it's all about?睡眠占用了我们一生三分之一的时间但是真正有人知道它到底是怎么回事吗？00:19Two thousand years ago, Galen, one of the most prominent medical researchers of the ancient world,proposed that while we're awake, our brain's motive force, its juice, would flow out to all the other parts of the body, animating them but leaving the brain all dried up, and he thought that when we sleep, all this moisture that filled the rest of the body would come rushing back, rehydrating the brain and refreshing the mind. Now, that sounds completely ridiculous to us now, but Galen was simply trying to explainsomething about sleep that we all deal with every day. See, we all know based on our own experiencethat when you sleep, it clears your mind, and when you don't sleep, it leaves your mind murky. But while we know a great deal more about sleep now than when Galen was around, we still haven't understood why it is that sleep, of all of our activities, has this incredible restorative function for the mind.两千年前古时候的名医伽林提出当我们醒着的时候我们大脑的原动力，它的液体会流动到身体所有其他部位维持它们的活力，但这却使大脑枯竭并且他认为，在我们睡觉的时候这些充满了我们身体其他部位的液体会再回到我们的大脑为大脑补充水分并且使我们更有精神虽然这些观点如今我们听来很荒谬但是伽林很好的解释了那些我们每天都要面对的睡眠的事情那么，根据自身的经验我们都知道如果我们睡觉了，我们的头脑会变的清醒而如果我们没有睡觉大脑就会变糊涂我们现在对睡眠的了解比伽林那个时期多了很多但是我们仍然不知道为什么在我们所有的活动中，只有睡眠有如此这般可以促使我们头脑变得清晰的功能01:17So today I want to tell you about some recent research that may shed new light on this question. We've found that sleep may actually be a kind of elegant design solution to some of the brain's most basic needs, a unique way that the brain meets the high demands and the narrow margins that set it apart from all the other organs of the body.所以今天，我想给大家讲一些近期的研究这些研究可能会揭示这些问题。

我们需要一个好的睡眠的英语作文Certainly! Here's an essay on the importance of good sleep, written from the perspective of an elementary school student, approximately 2,000 words in length:The Importance of Good SleepSleep is one of the most important things in life, and I can't imagine living without it! Just like how plants need sunlight and water to grow, we humans need sleep to stay healthy and happy. However, many of us don't get enough sleep, which can lead to all sorts of problems.Why is sleep so important? Well, for starters, it helps our bodies and minds recharge. When we sleep, our brains get a chance to rest and process all the information we've learned during the day. It's like hitting the "refresh" button on a computer – everything runs smoother and faster after a good night's rest.Sleep also helps our bodies grow and repair themselves. While we're sleeping, our bodies produce hormones that help us grow taller and stronger. It's like having a construction crew working overnight to fix up any damage or build new additions!Another important reason we need sleep is for our immune systems. When we don't get enough sleep, our bodies have a harder time fighting off germs and illnesses. It's like having a weak defense system against enemy invaders (the germs). With enough sleep, our immune systems are strong and ready to protect us.But that's not all! Sleep also affects our moods and behavior. Have you ever noticed how cranky and grumpy you feel when you're tired? That's because lack of sleep can make us irritable and have a harder time controlling our emotions. It's like being a ticking time bomb, ready to explode at the smallest thing.On the other hand, when we get enough sleep, we're more alert, focused, and in a better mood. It's like having a superpower that helps us pay attention in class, remember what we've learned, and be kinder to our friends and family.Unfortunately, many kids and adults these days don't get enough sleep. There are lots of reasons for this, like staying up late watching TV or playing video games, having too much homework or work to do, or even just feeling too excited or worried to fall asleep.But not getting enough sleep can have serious consequences. It can make us tired and sluggish during the day,have trouble concentrating in school or at work, and even affect our physical health in the long run.So, what can we do to make sure we get enough sleep? Here are some tips:Stick to a regular sleep schedule. Try to go to bed and wake up at the same time every day, even on weekends.Create a relaxing bedtime routine. Take a warm bath, read a book, or listen to calm music to help you wind down before bed.Keep your bedroom cool, dark, and quiet. Use curtains or blinds to block out light, and consider using a fan or white noise machine to drown out any distracting sounds.Avoid screens (TV, phones, tablets) for at least an hour before bedtime. The blue light from these devices can trick our brains into thinking it's daytime and make it harder to fall asleep.Get plenty of exercise and fresh air during the day. Being active and spending time outside can help you sleep better at night.Avoid caffeine and heavy meals too close to bedtime. Caffeine is a stimulant that can keep you awake, and digesting a big meal can make it harder to fall asleep.If you can't fall asleep after 20 minutes, get up and do a relaxing activity (like reading or listening to calm music) until you feel sleepy again.Getting enough sleep is just as important as eating healthy foods and exercising. It's not just a luxury – it's a necessity for our physical and mental well-being. So, let's all make sleep a priority and give our bodies and minds the rest they need!Remember, a well-rested kid (or adult) is a happier, healthier, and more productive one. Sweet dreams, everyone!。

The Necessity of Sleep for Middle SchoolStudentsAs middle school students, we often find ourselves caught up in a whirlwind of activities, homework, and extracurricular commitments. In the midst of this hustle and bustle, sleep often takes a backseat, with many of us sacrificing precious hours to finish tasks or engage in other activities. However, the importance of sleep for our physical and mental well-being cannot be overstated.Firstly, sleep is crucial for physical health. During sleep, our bodies repair and regenerate, building up immunity against diseases. Lack of sleep can lead to a weakened immune system, making us more susceptible to illness. Additionally, sleep is essential for growth and development, particularly for teenagers who are experiencing rapid physical changes.Moreover, sleep has a profound impact on our mental health. It enhances our cognitive functions, improving memory, concentration, and creativity. Sleep deprivation can lead to a decrease in these cognitive abilities, affecting our academic performance and daily life.Furthermore, lack of sleep can lead to mood swings, irritability, and even depression.In addition to its physical and mental benefits, sleep also plays a vital role in our emotional well-being. It helps us to decompress from the stresses of the day, enabling us to wake up refreshed and ready to face new challenges. Without sufficient sleep, we may find ourselves feeling overwhelmed and unable to cope with the demands of our daily lives.Given the importance of sleep, it is essential that we prioritize it in our daily schedules. While it may be tempting to stay up late to finish homework or participatein extracurricular activities, the long-term consequencesof sleep deprivation are not worth the short-term gains. By ensuring that we get enough sleep, we can improve our physical and mental health, enhance our cognitive abilities, and maintain a positive emotional state.In conclusion, sleep is a crucial aspect of our lives that should not be neglected. As middle school students, it is our responsibility to prioritize sleep and ensure thatwe get enough rest to support our physical, mental, andemotional well-being. By doing so, we can function at our best, achieve our goals, and enjoy a healthy and fulfilling life.**我们需要睡眠——初中生的视角**作为初中生，我们常常发现自己陷入了一场由各种活动、作业和课外承诺组成的旋风之中。

那一刻,我为什么要睡觉作文英文回答：When I think back to that moment, I can't help but wonder why I chose to sleep. It was a decision that would ultimately alter the course of my life in ways I couldnever have imagined.Perhaps it was the allure of escape. The weight of the world had been pressing down on me, and the promise of oblivion seemed like a tempting reprieve. In the darknessof my slumber, I could forget my troubles and find solacein the void.Or maybe it was a subconscious self-sabotage. Deep down, I knew that staying awake would mean confronting the harsh realities of my life. I was afraid of what the future held, and so I retreated into the safety of sleep.Whatever the reason, that choice to sleep has hauntedme ever since. It was a moment of weakness, a missed opportunity. I can't help but wonder what might have happened if I had stayed awake, if I had faced my fears and embraced the unknown.The consequences of my slumber are still unfolding. I have missed out on experiences, relationships, and opportunities that I can never reclaim. I have allowed regrets and doubts to fester in my mind, poisoning my present and casting a shadow over my future.I know that I cannot change the past, but I can learn from my mistakes. I will never again let the allure of sleep lead me astray. I will embrace the challenges of life with courage and determination. I will not waste my precious time on meaningless pursuits.I will make the most of every moment, knowing that the passage of time is relentless and that the choices we make today will shape our tomorrows.中文回答：那一刻，我为什么要睡觉？我百思不得其解。

关于睡眠，你又了解多少?睡眠专家Russell Foster为我们解答为什么要睡觉，以及睡眠对健康的影响。

What I'd like to do today is talk about one of my favorite subjects, and that is the neuroscience of sleep.Now, there is a sound -- (Alarm clock) -- aah, it worked -- a sound that is desperately, desperately familiar to most of us, and of course it's the sound of the alarm clock. And what that truly ghastly, awful sound does is stop the single most important behavioral experience that we have, and that's sleep. If you're an average sortof person, 36 percent of your life will be spent asleep, which means that if you live to 90, then 32 years will have been spent entirely asleep.Now what that 32 years is telling us is that sleep at some levelis important. And yet, for most of us, we don't give sleep a second thought. We throw it away. We really just don't think about sleep.And so what I'd like to do today is change your views, change your ideas and your thoughts about sleep. And the journey that I want to take you on, we need to start by going back in time."Enjoy the honey-heavy dew of slumber." Any ideas who said that? Shakespeare's Julius Caesar. Yes, let me give you a few more quotes. "O sleep, O gentle sleep, nature's soft nurse, how have I frighted thee?" Shakespeare again, from -- I won't say it -- the Scottish play. [Correction: Henry IV, Part 2] (Laughter) From the same time: "Sleepis the golden chain that ties health and our bodies together." Extremely prophetic, by Thomas Dekker, another Elizabethan dramatist.But if we jump forward 400 years, the tone about sleep changes somewhat. This is from Thomas Edison, from the beginning of the 20th century. "Sleep is a criminal waste of time and a heritage from our cave days." Bang. (Laughter) And if we also jump into the 1980s, someof you may remember that Margaret Thatcher was reported to have said, "Sleep is for wimps." And of course the infamous -- what was his name? -- the infamous Gordon Gekko from "Wall Street" said, "Money never sleeps."What do we do in the 20th century about sleep? Well, of course,we use Thomas Edison's light bulb to invade the night, and weoccupied the dark, and in the process of this occupation, we'vetreated sleep as an illness, almost. We've treated it as an enemy. At most now, I suppose, we tolerate the need for sleep, and at worst perhaps many of us think of sleep as an illness that needs some sortof a cure. And our ignorance about sleep is really quite profound.Why is it? Why do we abandon sleep in our thoughts? Well, it's because you don't do anything much while you're asleep, it seems. You don't eat. You don't drink. And you don't have sex. Well, most of us anyway. And so therefore it's -- Sorry. It's a complete waste of time, right? Wrong. Actually, sleep is an incredibly important part of our biology, and neuroscientists are beginning to explain why it's sovery important. So let's move to the brain.Now, here we have a brain. This is donated by a social scientist, and they said they didn't know what it was, or indeed how to use it, so -- (Laughter) Sorry. So I borrowed it. I don't think they noticed. Okay. (Laughter)The point I'm trying to make is that when you're asleep, thisthing doesn't shut down. In fact, some areas of the brain areactually more active during the sleep state than during the wake state. The other thing that's really important about sleep is that it doesn't arise from a single structure within the brain, but is to some extent a network property, and if we flip the brain on its back -- I love this little bit of spinal cord here -- this bit here is the hypothalamus, and right under there is a whole raft of interesting structures, not least the biological clock. The biological clocktells us when it's good to be up, when it's good to be asleep, and what that structure does is interact with a whole raft of other areas within the hypothalamus, the lateral hypothalamus, the ventrolateral preoptic nuclei. All of those combine, and they send projections down to the brain stem here. The brain stem then projects forward and bathes the cortex, this wonderfully wrinkly bit over here, with neurotransmitters that keep us awake and essentially provide us with our consciousness. So sleep arises from a whole raft of different interactions within the brain, and essentially, sleep is turned onand off as a result of a range ofOkay. So where have we got to? We've said that sleep is complicated and it takes 32 years of our life. But what I haven't explained is what sleep is about. So why do we sleep? And it won't surprise any of you that, of course, the scientists, we don't have a consensus. There are dozens of different ideas about why we sleep,and I'm going to outline three of those.The first is sort of the restoration idea, and it's somewhat intuitive. Essentially, all the stuff we've burned up during the day, we restore, we replace, we rebuild during the night. And indeed, asan explanation, it goes back to Aristotle, so that's, what, 2,300 years ago. It's gone in and out of fashion. It's fashionable at the moment because what's been shown is that within the brain, a wholeraft of genes have been shown to be turned on only during sleep, and those genes are associated with restoration and metabolic pathways.So there's good evidence for the whole restoration hypothesis.What about energy conservation? Again, perhaps intuitive. You essentially sleep to save calories. Now, when you do the sums, though, it doesn't really pan out. If you compare an individual who has slept at night, or stayed awake and hasn't moved very much, the energy saving of sleeping is about 110 calories a night. Now, that's the equivalent of a hot dog bun. Now, I would say that a hot dog bun is kind of a meager return for such a complicated and demanding behavior as sleep. So I'm less convinced by the energy conservation idea.But the third idea I'm quite attracted to, which is brain processing and memory consolidation. What we know is that, if after you've tried to learn a task, and you sleep-deprive individuals, the ability to learn that task is smashed. It's really hugely attenuated. So sleep and memory consolidation is also very important. However,it's not just the laying down of memory and recalling it. What's turned out to be really exciting is that our ability to come up with novel solutions to complex problems is hugely enhanced by a night of sleep. In fact, it's been estimated to give us a threefold advantage. Sleeping at night enhances our creativity. And what seems to be going on is that, in the brain, those neural connections that are important, those synaptic connections that are important, are linked and strengthened, while those that are less important tend to fade away and be less important.Okay. So we've had three explanations for why we might sleep, and I think the important thing to realize is that the details will vary, and it's probable we sleep for multiple different reasons. But sleepis not an indulgence. It's not some sort of thing that we can take on。

my chinese dream 我的中国梦i am very glad to stand here to give thier a short speech.today my topic is thatthe youth are the future of motherland 很高兴站在这里做这篇短小的演讲，我演讲的主题是青年是祖国的未来。

在准备英语演讲比赛的时候，我本想简单地从网上搜索一些文章作为我演讲的内容。

我看过很多文章，有著名主持人的、北大教授的、大学生的，也有初中生的。

但是看完之后，我放弃了当初的想法，我甚至为当初的想法感到有一些羞愧。

因为今天我站在这里向大家演讲的主题，是一个庄重而严肃的主题；是一个充满荣耀与自豪的主题；是每一个中华儿女共同期盼的主题。

每个人都有属于他们自己的中国梦，而我，当然也有一直萦绕在心怀只属于我的中国梦。

so what?s my chinese dream ? finally i will announce. we had learned a lot of knowledge and understood a lot of truth in the book. wehad a basic concept to our country at that time. we know that our country is fullof sunshine , and we are the future of our country, and our dreams are to be the hopeof our motherland.我的中国梦是什么样的？先卖个关子。

记得刚刚上学那会儿，我们天真无邪。

在课本里，我们学到了很多很多知识，也明白了很多很多道理，我们对祖国也有了一个最基本的概念。

我们知道我们的祖国到处充满阳光，正在慢慢发展，而我们，就是祖国未来的花朵，未来的希望。
