Why do meteors have a streak of light??
As they travel through our atmosphere, meteors collide with air molecules that knock away materials and strip electrons from the meteor… When the stripped atoms recapture electrons, light is emitted… The color of the light depends on the temperature and the material being “excited.”

Specific Meteor Showers
Meteor showers occur on a regular basis throughout the year, but not all are visible in the northern latitudes & some are very weak and easily go unnoticed… Some of the more impressive showers throughout a given year are: Shower Avg. Peak - Quadrantids – early January - Lyrids – mid April - Perseids – early/mid August - Orionids – mid/late October - Leonids – mid November - Geminids – mid December ** Historically, the Perseids in August & the Leonids in November have been the most impressive meteor showers /meteors/images/18nov01_page3/ cordiale1.mov

SCIENCE REPORT - The Perseid Meteor Shower

SCIENCE REPORT - The Perseid Meteor Shower

SCIENCE REPORT - August 2, 2001: The Perseid Meteor ShowerBy Mario RitterThis is the VOA Special English Science Report.This month, you can see with your own eyes how material from space falls to Earth.Space material, which is mostly rock, is often captured by Earth’s gravity and falls to the surface of our planet. These falling space rocks are called meteors. Large numbers of meteors fall during a meteor shower. The Perseid (PER-see-id) meteor shower is the most famous of these events.The Perseid meteor shower happens in early August every year. The largest number of meteors is expected to fall on August twelfth. Scientists measure meteor showers by the average number of meteors that fall in an hour. About ninety-five meteors fall in an hour during the most active day of the Perseid shower.The Italian scientist Giovanni Schiaparelli named the Perseid meteor shower in Eighteen-Sixty-Six. He called it the Perseid meteor shower because its meteors appear to come from the group of stars called Perseus (PER-see-us). Meteor showers are named for the group of stars, or constellation, from which they come.Mister Schiaparelli discovered that the Perseid meteors had the same orbit as a comet, another kind of space object. A comet is a large body of gas, ice and rock. The Italian astronomer found that the Comet Swift-Tuttle had the same orbit as the Perseid meteors. Mister Schiaparelli’s discovery showed that meteor showers come from material left behind by comets.Traditionally, people believed that meteors were a weather event. Edward Herrick of New Haven, Connecticut, was one of the early theorists who suggested that meteors came from space. In Eighteen-Thirty-Eight, Mister Herrick published a report claiming to have discovered a meteor shower in August.But he soon found that people had observed the August meteor showers for centuries. One German tradition calls the Perseid meteors the “tears of Saint Lawrence.” This was in honor of a religious person who was put to death by the Romans in the Third Century. The anniversary of the death of Saint Lawrence is August tenth.To see the Perseids all you need to do is to watch the sky. This year, the moon will brighten the sky, making it more difficult to see meteors. But you still should be able to see about one meteor every minute during the early morning hours of August twelfth.This VOA Special English Science Report was written by Mario Ritter.Email this article to a friendPrinter Friendly Version。

看流星雨英文作文带翻译英文:I remember the first time I saw a meteor shower. It wasa warm summer night, and I was camping with my friends inthe mountains. We had heard about the meteor shower and decided to stay up late to watch it. As the night grew darker, we could see more and more shooting stars streaking across the sky. It was such a magical and awe-inspiring experience.I couldn't help but make a wish every time I saw a shooting star. It felt like a rare opportunity to make my dreams come true. My friends and I took turns pointing out the brightest and most impressive meteors, and we eventried to count how many we saw. We lost count after a while, but it didn't matter. The sheer beauty of the meteor shower was enough to leave us speechless.As the night went on, we huddled around a campfire,sharing stories and laughing together. It felt like we were part of something much bigger than ourselves, connecting with the universe in a way that was both humbling and exhilarating. I'll never forget that night and the feeling of wonder and excitement that the meteor shower brought.中文:我记得第一次看到流星雨的时候。

热点27 彗星以及流星与流星雨(原卷版)中考英语考前时事热点话题阅读

备战2022年中考英语考前时事热点话题阅读+题型专练热点27 彗星以及流星与流星雨一、阅读理解1Since ancient times, human beings have looked up at the night sky. Comets (彗星) and meteors (流星) flying through the blackness were seen as signs from the gods. They were used to tell the future of human lives.In 2013, a meteorite shower hit an area in Russia. It injured around 1,200 people. In ancient times, this would have been a strange and terrible experience. Today, thought, science offers simple explanations for the occurrence (事件).Meteorites are small pieces of debris (碎片) that float around in space. Sometimes, they come near a planet, such as Earth. When they enter our atmosphere, they often heat up and become very bright. This is why they are sometimes called “fireballs”. They are usually mad e of metals, such as iron (铁), and other minerals (矿物). The Russian meteorites were stony, with iron making up 10 percent of them.Meteorite showers, such as that in Russia, happen when a large meteor enters the Earth’s atmosphere and, due to heat, breaks up into small parts. Most of these are very small — smaller than a grain of sand —and so don’t even make it to the ground. But others can cause a lot of damage.The meteor in Russia weighed 10 tons when it entered our atmosphere, and broke up about 20-30 miles (30-50 km) above ground. The sky was filled with bright lights and loud noises. Many windows were broken. The damage cost Russia around 206 million yuan.1. What did people in ancient times think when they saw a meteorite shower?A. It was a wonderful sight.B. It was common in nature.C. They respected it as a god.D. They felt puzzled and scared.2. Which of the following is NOT true about meteorites?A. They float around in space.B. They often heat up when entering Earth.C. There are fires around them.D. They are usually made of metals.3. When a large meteor comes into the Earth’s atmosphere, ___________.① meteorite showers happen② it breaks up into small pieces③ it falls to the ground as whole④ it seldom causes serious damageA. ①②B. ①③C. ①④D. ②④4. Which topic does the story NOT talk about?A. How meteorite showers happen.B. How to stop meteorite showers.C. The meteorites in Russia.D. The damage meteorites can cause.2There are lots of objects that we see in the sky. During the day we see the sun. After the sunset in the evening, we see mostly the stars. Not all the lights in the sky that we see are really stars.Of course, we see the moon. Some of the other lights in the sky are planets(行星). Planets go around the sun like earth does.Sometimes we can see a shooting star. Shooting star looks like a star that is moving quickly across the sky. Some people believe that seeing a shooting star will bring them good luck. It's hard to find shooting star because they run fast.The correct name for shooting star is meteor(流星). Space has lots of little objects. These can be rocks in space from old planets. These objects can be very small, they are called meteorites(陨石). When meteorite gets close to the earth, it gets pulled towards the earth by gravity(重力). Earth is surrounded by atmosphere(大气层). Atmosphere is made up of air and clouds. Meteorite burns in the earth's atmosphere. This makes the short bright moving light in the night sky. A meteorite then turns into meteor.5. At night the sky is filled mostly with ________.A. the moonB. the planetsC. the starsD. the sun6. From the passage, we can know ________.A. all the lights in the sky that we see are really starsB. space has lots of little objects and they can be rocks from old planets.C. when a meteorite is near the earth, it gets pushed from the earth by gravity.D. shooting star looks like star that is moving slowly across the sky.7. How does a meteorite turn into a meteor? Please put the following sentences in order.①It is pulled towards the earth by gravity.②The burning gives off bright light.③A meteorite gets close to the earth.④It burns in the earth's atmosphere.A. ③④②①B. ③④①②C. ③①④②D. ③②①④8. Where can we probably read this passage?A. In a diary.B. In a science magazine.C. In an advertisement.D. In a novel.3BOOM! That’s a word we often use to describe a loud sound. It’s also part of the term “sonic boom (音爆)”, which is something that happens when air is pushed so strongly and quickly that it creates a loud noise.On March 20, a rare daytime meteor (流星) created a sonic boom over parts of the UK and France, according to Live Science. The meteor flew through the sky so fast that it could hardly be seen - but it could definitely be heard.So how exactly are sonic booms made? You can think of air as being like water. When something moves through water, you can see ripples (波纹). If the object moves very quickly, the ripples start to run into each other.The same thing happens in the air, even if it can’t be seen. When the object moves faster than the speed of sound, the air is pushed hard, and it compresses (压缩) like the ripples on water. This will create a sound wave that is very loud, which is a sonic boom.In fact, lots of things can make sonic booms. When you go to the park and see people play with whips and tops (鞭子和陀螺), you might hear a tiny sonic boom when they crack the whip. Aircraft that travel faster than the speed of sound can also make sonic booms.A strong sonic boom can cause damage to windows or buildings, although the possibility of this is very low, according to the US Air Force. The loud sound can also disturb (影响) people on the ground and even cause hearing loss. That’s why supersonic aircraft are only allowed in tim es of war.9. Which of the following wouldn’t cause a sonic boom?A. a meteorB. whips and topsC. supersonic aircraftD. water ripples10. In paragraph 3, the writer mentions water to ________.A. help explain how a sonic boom happens.B. describe what water ripples look likeC. prove that water can move like air.D. explain the differences between water ripples and sonic booms.11. According to the passage, a sonic boom is something that ________.A. happens when air is pushed softly and slowlyB. never appears as a loud soundC. may cause damage to your houseD. can be seen when it happens12. On which website can we probably read this passage?A. /historyB. /soundC. /powerD. www.airforcexom/aircraft4I’m Victor. On my seventh birthday, my mom gave me a book about stars. That was the beginning of my lifetime hobby.I always went outside with my mom on clean nights and looked at the sky. In different seasons. we saw different groups of stars. Sometimes we saw stars shooting brightly(明亮地)across the sky. How beautiful they were!Studying the stars was great fun for me . When I learnt a little about them, Iwanted to find out more and more. Now it is my job. I host a TV show called The Sky at Night. I use what I know to tell people about the stars in a great way. I am happy because my TV show started over 50 years ago, now it’s still popular.Now I am seventy-five years old. Actually, I think you can turn your hobby into your job too. Anybody can make their dreams come true. You just have to enjoy what you do!13. The underlined word “shooting” means .A. 飞过B. 闪耀C. 眨眼D. 唱歌14. “Studying the stars was great fun for me.”tells us .A. Victor was interested in starsB. Victor loved the book very muchC. Victor often saw different starsD. Victor loved his TV show15. The sky at Night is over years old.A. 7B. 50C. 65D. 7516. The writer wants to tell us that .A. hobbies are just jobsB. TV show helps us a lotC. we need to enjoy what we doD. reading is important in our life5If you look at the sky one night and see something moving and shining that you have never seen before, itmight be a comet (彗星).A comet sometimes looks like a star. Like a planet, a comet has no light of its own. It shines from the sunlight it reflects (反射). Like the earth, a comet goes round the sun, but on a much longer path (轨道) than the earth travels.If a comet isn’t a star, what is it then?Some scientists think that a large part of a comet is water frozen into pieces of ice and mixed with iron and rock dust and perhaps a few big pieces of rock. When sunshine melts (融化) the ice in the comet, great clouds of gas go trailing after it. These clouds, together with the dust, form a long tail.Many people perhaps have seen a comet. However no one knows how many comets there are. There may be millions of comets, but only a few come close enough for us to see.An Englishman named Edmund Halley, who lived from 1656 to 1742, found out a lot about the paths that comets take through the sky. Some comets move out of our sight and never come back. Others keep coming back at regular times. A big comet that keeps coming back was named after Halley because he was the one who worked out when it would come back again. Maybe you have ever seen Halley’s Comets because the last time it came close to the sun and the earth was in the year 1986. Then people all over the world were outside at night to look at it. You will probably be able to see Halley’s Comets when it comes near the earth again.17. A comet is like ________.A. sunB. moonC. sunlightD. the earth18. A large part of a comet is ______.A. water and rockB. water frozen into pieces of ice and mixed with ironC. ice, iron and rock dustD. only a few big pieces of rock19. Maybe many people _______.A. haven’t seen any cometsB. have seen all cometsC. have seen a comet at daytimeD. have seen a comet20. Some comets keep coming back ________.A. at any timeB. at noonC. at regular timesD. at daytime21. Halley’s Comets came back _____.A. in 1990B. in 1980C. in 1986D. in 19896Comets(彗星) are parts of our solar system. Like the planets, they go around the sun.But comets are not made of solid rocks like planets. A comet is a ball of dust, stones, and ice. Many people call comets dirty snowballs.The “snowball” may be only a few miles across. But when the sun heats the “snowball,” much of it is changed to gases. The gases spread out and form the comet’s head, which may be thousands of miles across.A comet moves fast in its trip around the sun. But when we see it, the comet does not seem to move. That’s because it is so far away. The moon moves fast, bu t when you look at it, you can’t see any motion(运动). That’s because the moon is far away.Each year astronomers(天文学家) discover new comets. Some of them are seen only once. They make one trip around the sun and then go away out into space. The sun’s gravi ty cannot hold them.Other comets, like Halley, keep returning. They have been captured by the sun. Halley’s earliest visit was probably 3,000 years ago. It may keep returning for another 3,000 years.But every time a comet goes around the sun, the comet loses part of itself. Gases and dust are pulled out of the comet. That’s why Halley is now dimmer(暗淡的)than it used to be. Next time it visits us, in 2062, it may be even dimmer. Each visit it may get dimmer and dimmer, until it finally disappears.22. What is this passage mostly about?A. Comets and the sun.B. Why comets are like snowballs.C. Who discovered the first comet.D. Facts about comets.23. How does the writer help the reader understand what a comet looks like?A. By telling about a famous one.B. By explaining how far away it is.C. By describing how fast it moves.D. By describing it as a dirty snowball.24. What is the most likely reason the writer wrote this passage?A. To give information about comets.B. To tell readers about famous comets.C. To explain the importance of comets.D. To encourage readers to look for comets.7The planets aren’t the only wanderers(漫游者) of the sky. There’re some things even farther and longer. Long after people were no longer afraid of planets, they still thought the comets(彗星) were bad objects that traveled in the sky. They were afraid that the comets would suddenly land on the earth and hurt them.But, in fact, even if a comet did hit the earth, nothing much happened. A comet is really a harmless (无害的)thing.Comets have round heads and long tails , and they are very bright. Sometimes they look like heads with long hair flying with them. That’s why they’re called comets. Comet means long-haired.Like the stars and planets, comets are far away. But we can know its size. The head of a small comet is as wide as the Pacific Ocean. And a big comet’s head is ten times as big as the earth. Its tail is millions of kilometers long. Then why wouldn’t the great big thing hurt us if it hit the earth? Because it isn’t solid. It’s thin like cloud. Its tail is nothing but bright gas. And its head is made of small pieces and they could not hurt the earth.Some comets can be seen for a few months. Then they go away. Some of them come back in a certain number of years. Some are never seen again.Perhaps these comets that never return have broken into pieces. For some______think that shooting stars(流星) are pieces of broken comets.25. People were afraid ________.A. comets are different from planetsB. comets travel in the skyC. comets are much bigger than the earthD. comets could hit the earth26. Comets have long tail like ________, so we call them comets.A. long hairB. round headsC. round dishesD. wide wings27. From the passage we know the tails of comets are made of ________.A. waterB. solidC. gasD. small stones28. The underlined word “astronomers”may mean ________ in Chinese.A. 心理学家B. 艺术家C. 天文学家D. 考古专家29. Which of the following is TRUE ?A. A comet is a kind of planets.B. Comets are all ten times as big as the earth.C. People can hardly see comets.D. Shooting stars may come from the broken comets.二、完型填空Maria Mitchell was born in 1818 during a time when many people thought that woman did not need to learn .

关于流星雨的英文作文高中

关于流星雨的英文作文高中

关于流星雨的英文作文高中Last night, I saw a shooting star streak across the sky. It was so bright and beautiful, and it made me feel like anything is possible.I remember the first time I saw a meteor shower. I was camping with my family in the mountains, and we stayed up late to watch the show. It was like fireworks in the sky, and I felt so small and insignificant in comparison to the vastness of the universe.When I was a kid, I used to make wishes on shooting stars. I would close my eyes tight and make a secret wish, hoping that it would come true. Even though I know it'sjust a superstition, there's something magical about the idea of a shooting star granting your deepest desires.Some people believe that meteor showers have aspiritual significance. They think that the energy of the shooting stars can bring about positive changes in theirlives. Whether it's true or not, I think it's nice to believe in something bigger than ourselves.One of the most amazing things about meteor showers is that they happen all over the world. It's a reminder that we're all connected by the same sky, and that we're all part of something much larger than our individual lives.I hope I never lose my sense of wonder when it comes to shooting stars. There's something so special about seeing a meteor streak across the sky, and I never want to take that feeling for granted.。

小学奥数模块教程周期问题(A级)

小学奥数模块教程周期问题(A级)

流星雨(Meteor Shower)的产生一般认为是由于流星体与地球大气层相摩擦的结果(流星体可以是小行星带上的小行星),流星群往往是由彗星分裂的碎片产生,因此,流星群的轨道常常与彗星的轨道相关。

成群的流星就形成了流星雨。

流星雨看起来像是流星从夜空中的一点迸发并坠落下来。

这一点或这一小块天区叫作流星雨的辐射点。

通常以流星雨辐射点所在天区的星座给流星雨命名,以区别来自不同方向的流星雨。

例如每年11月1 7 日前后出现的流星雨辐射点在狮子座中,就被命名为狮子座流星雨。

猎户座流星雨、宝瓶座流星雨、英仙座流星雨也是这样命名的。

单个出现的流星,在方向和时间上都很随机,也无任何辐射点可言,这种流星称为偶发流星。

与偶发流星有着本质不同的流星雨的重要特征之一,是所有流星的反向延长线都相交于辐射点。

世界上最早的关于流星雨的记载是在公元前687年,中国关于天琴座流星雨的记载:“夜中星陨如雨”。

同学们你们知道科学家是如何知道什么时间出现美丽而又神秘的流星雨吗? 这就用到了我们今天的学习内容,周期问题。

周期问题:周期现象:事物在运动变化过程中,某些特征有规律循环出现;周期:我们把连续两次出现所经过的时间叫周期;解决有关周期性问题的关键是确定循环周期.分类: 1.图形中的周期问题; 2.数列中的周期问题; 3.年月日中的周期问题.周期性问题的基本解题思路是:首先要正确理解题意,从中找准变化的规律,利用这些规律作为解题的依据;其次要确定解题的突破口。

主要方法有观察法、逆推法、经验法等。

主要问题有年月日、星期几问题等。

流星的英语单词

流星的英语单词

流星的英语单词Meteors, also known as shooting stars, are fascinating celestial events that have captivated humans for centuries. These streaks of light across the night sky have inspired countless myths, legends, and wishes. In this article, we will explore the vocabulary related to meteors and delve into the science behind these mesmerizing phenomena.1. Meteor:A meteor is a small celestial body that enters the Earth's atmosphere and burns up upon contact, creating a streak of light. These objects are typically fragments of asteroids or comets. As they travel through the atmosphere, they experience intense heat and friction, causing them to glow and become visible from the ground.2. Meteoroid:A meteoroid is a small rocky or metallic object that exists in space. It is the precursor to a meteor and can range in size from a grain of sand to a boulder. Meteoroids are remnants of asteroids or comets that have broken apart due to collisions or gravitational forces.3. Meteorite:If a meteoroid survives its journey through the Earth's atmosphere and lands on the surface, it is called a meteorite. Meteorites provide valuable insights into the composition and history of our solar system. Scientists study them to understand the processes that shaped our planet and the universe.4. Meteor Shower:A meteor shower occurs when the Earth passes through a trail of debris left behind by a comet or asteroid. These showers are named after the constellation from which the meteors appear to originate. For example, the Perseids meteor shower is named after the Perseus constellation. During a meteor shower, the number of visible meteors increases significantly, creating a spectacular display in the night sky.5. Radiant:The radiant is the point in the sky from which the meteors of a meteor shower appear to originate. It is an apparent point caused by the Earth's motion intersecting with the meteoroid stream. Observers can locate the radiant by tracing the path of the meteors backward, which will converge at a specific point.6. Fireball:A fireball is an exceptionally bright meteor that illuminates the sky with its intense light. Fireballs are often accompanied by a loud noise, known as a sonic boom, due to their high velocity and atmospheric pressure. These dramatic events are a rare sight but leave a lasting impression on those fortunate enough to witness them.7. Bolide:A bolide is an extremely bright fireball that explodes in the atmosphere. The explosion releases a tremendous amount of energy, causing a bright flash and sometimes even a shockwave. Bolides can be as bright as the full moon and are often accompanied by a sonic boom.8. Meteorite Impact:Although rare, meteorites can cause significant damage when they collide with the Earth's surface. These impacts have shaped our planet's geological history and have even led to mass extinctions. Famous examples include the Chicxulub impact, which is believed to have caused the extinction of dinosaurs.In conclusion, meteors are captivating natural phenomena that continue to intrigue and inspire us. From the moment a meteoroid enters our atmosphere to the rare occurrence of a meteorite impact, these events remind us of the vastness and beauty of the universe. By understanding the vocabulary associated with meteors, we can appreciate these celestial wonders even more. So, next time you gaze at the night sky and spot a shooting star, remember the journey it has taken and the secrets it holds.。

雅思天文类词汇

雅思天文类词汇

雅思天文类词汇我们都知道太阳系是由太阳为中心的一个行星体系。

「太阳」的话我们叫做 sun,而太阳系就是 solar,solar system 就是太阳系的意思。

众所周知,太阳是一个恒星,「恒星」的话,我们称之为 a permanent star,permanent 这个词是「永恒的,永垂不朽的」,也可以称之为一颗固定的星星,叫 a fixed star。

我们说所有的星星都被称之为天体,「天体」这个词叫什么呢,叫 celestial bodies。

celestial 表示的是「天上的」,我们经常说「神兽」,各个国家都是有神兽的,西方有龙,中国有龙、麒麟、凤凰等等。

这些神兽无一不具备一种功能,都是能够在天上飞的。

神兽的英文就是刚刚我们讲的 celestial 加上一个 animal,所以说神兽的英文叫什么,叫做 celestial animals。

而行星除了叫 celestial bodies,他还可以叫什么呢,叫做 planet,这个词能在古希腊语当中表示是「徘徊,漫步」的意思。

我们想一想所有的星星在天空中在宇宙当中自由的徘徊、漫步是不是非常的浪漫呢?接下来我们看一下太阳系的八大行星,加上已经被开除出太阳系的冥王星,首先离太阳最近的叫水星,水星的英文叫Mercury,它的化学名称叫做汞,俗称叫做水银。

水星的话呢,Mercury 中文叫墨丘利。

他在古罗马神话中,水星的是商业、旅行和偷窃之神。

我们要知道,除了地球,从水星到冥王星,它的名字都来自于古罗马神话或者是古希腊神话。

水星的话,那在古罗马神话中是商业、旅行、偷窃之神。

他对应的古希腊神话的名字叫什么叫做赫尔墨斯 Hermes,是为众神传递信件、传递讯息的神,或许是由于水星它在空中的移动速度是比较快的,所以说他就能拿到这个名字。

刚刚说的他的希腊神话的名字叫 Hermes,就是「爱马仕」的称呼。

推荐大家听一首歌叫做《水星记》《水星记》是由一个独立创作人叫郭顶的人写的。

小学奥数模块教程周期问题(C级)

小学奥数模块教程周期问题(C级)

流星雨(Meteor Shower)的产生一般认为是由于流星体与地球大气层相摩擦的结果(流星体可以是小行星带上的小行星),流星群往往是由彗星分裂的碎片产生,因此,流星群的轨道常常与彗星的轨道相关.成群的流星就形成了流星雨.流星雨看起来像是流星从夜空中的一点迸发并坠落下来.这一点或这一小块天区叫作流星雨的辐射点.通常以流星雨辐射点所在天区的星座给流星雨命名,以区别来自不同方向的流星雨.例如每年11月1 7 日前后出现的流星雨辐射点在狮子座中,就被命名为狮子座流星雨.猎户座流星雨、宝瓶座流星雨、英仙座流星雨也是这样命名的.单个出现的流星,在方向和时间上都很随机,也无任何辐射点可言,这种流星称为偶发流星.与偶发流星有着本质不同的流星雨的重要特征之一,是所有流星的反向延长线都相交于辐射点.世界上最早的关于流星雨的记载是在公元前687年,中国关于天琴座流星雨的记载:“夜中星陨如雨”.同学们你们知道科学家是如何知道什么时间出现美丽而又神秘的流星雨吗? 这就用到了我们今天的学习内容,周期问题.课前预习周期问题周期问题:周期现象:事物在运动变化过程中,某些特征有规律循环出现;周期:我们把连续两次出现所经过的时间叫周期;解决有关周期性问题的关键是确定循环周期.分类: 1.图形中的周期问题; 2.数列中的周期问题; 3.年月日中的周期问题.周期性问题的基本解题思路是:首先要正确理解题意,从中找准变化的规律,利用这些规律作为解题的依据;其次要确定解题的突破口.主要方法有观察法、逆推法、经验法等.主要问题有年月日、星期几问题等.⑴观察、逆推等方法找规律,找出周期.确定周期后,用总量除以周期,如果正好有整数个周期,结果就为周期里的最后一个;例如:1,2,1,2,1,2,…那么第18个数是多少? 这个数列的周期是2,1829÷=,所以第18个数是2. ⑵如果比整数个周期多n 个,那么为下个周期里的第n 个; 例如:1,2,3,1,2,3,1,2,3,…那么第16个数是多少? 这个数列的周期是3,16351÷=⋅⋅⋅,所以第16个数是1.⑶如果不是从第一个开始循环,可以从总量里减掉不是循环的个数后,再继续算. 例如:1,2,3,2,3,2,3,…那么第16个数是多少?这个数列从第二个数开始循环,周期是2,(161)271-÷=⋅⋅⋅,所以第16个数是2.1.找准变化的规律 2.确定解题的突破3. 同余知识的应用(杯赛考试涉及)重难点知识框架例题精讲【例 1】小兔和小松鼠做游戏,他们把黑、白两色小球按下面的规律排列:●○○●●●○●●○●●○…你知道它们所排列的这些小球中,第90个是什么球?第100个又是什么球呢?【巩固】黑珠、白珠共101颗,穿成一串,排列如下图.这串珠子中,最后一颗珠子应该是_____色的,这种颜色的珠子在这串中共有_____颗.【例 2】有47盏灯,按二盏红灯、四盏蓝灯、三盏黄灯的顺序排列着.最后一盏灯是什么颜色的?三种颜色的灯各有多少盏?【巩固】流水线上给小木球涂色的次序是:先5个红、再4个黄、再3个绿、在2个黑、再1个白,然后又依次是5红、4黄、3绿、2黑、1白……如此继续涂下去,到第2003个小球该涂什么颜色?【例 3】在图所示的表中,将每列上、下两个字组成一组,例如第一组为(智成),第二组为(康就),那么第48组是什么智康一对一智康一对一智康一对一智康一对一……成就学生务实创新成就学生务实创新成就学生务实创新……【巩固】在图所示的表中,将每列上、下两个字组成一组,例如第一组为(新奥),第二组为(北林),那么第50组是什么?新北京新奥运新北京新奥运新北京新奥运……奥林匹克运动会奥林匹克运动会奥林匹克运动会……【例 4】如右图,是一片刚刚收割过的稻田,每个小正方形的边长是1米,A、B、C三点周围的阴影部分是圆形的水洼.一只小鸟飞来飞去,四处觅食,它最初停留在0号位,过了一会儿,它跃过水洼,飞到关于A点对称的1号位;不久,它又飞到关于B点对称的2号位;接着,它飞到关于C点对称的3号位,再飞到关于A点对称的4号位,……,如此继续,一直对称地飞下去.由此推断,2004号位和0号位之间的距离是多少米?【巩固】下表的第一行的文字和第二行的字母都有各自的周期,那么第2011列的文字和字母分别是什么?列数 1 2 3 4 5 6 7 8 9 10 (150)文字轻松学奥数轻松学奥数…字母 A B C D A B C D A B …模块二、数列中的周期问题【例 5】全班39名同学围成一圈做游戏,中间放着400颗石子,由班长开始,沿顺时针方向拿石子,每人每次拿5颗,直到拿完,那么,班长最后可以拿到几颗石子?【巩固】康康和其他5个小朋友围成一圈,圆圈中央摆放这55个乒乓球,从康康开始,小朋友们沿逆时针方向开始拿球,每人每次拿3个,知道把乒乓球全部拿完为止(最后剩下的球不足3个就全拿走),那么,康康共拿了多少个球?【例 6】分别姓赵、钱、孙、李、周、吴、王的七位同学站成一排,按照下列方式依次报数:报2011的同学姓()【巩固】将偶数如右表排列,那么2058这个数应排在第几列?一二三四五2 4 6 816 14 12 1018 20 22 2432 30 28 2634 36 38 40…………【例 7】右图中,任意三个连续的小圆圈内三个数的连乘积都是891,那么B代表多少?【例 8】紧接着1989后面一串数字,写下的每个数字都是它前面两个数字的乘积的个位数.例如 8×9=72,在9后面写2,9×2=18,在2后面写8……得到一串数字:1 9 8 9 2 8 6……这串数字从1开始往右数,第2002个数字是什么?【巩固】有一个111位数,各位数字都是1,这个数除以6,余数是几?商的末位数字是几?【例 9】若今天是星期六,从今天起102011天后的那一天是星期( ).【巩固】如果6月9日是星期五,那么再过19951995天是星期( ).【例 10】已知某个月所有星期天的日期加起来是85,这个月的最后一个星期天是()号.【巩固】有一个电子钟,每走9分钟亮一次灯,每到整点时响一次铃,中午12时整,电子钟响铃又亮灯,问下一次既响铃又亮灯是()时.课堂检测1. 20092009+20102010+20112011的个位数字是().2. 伸出你的左手,从大拇指开始如图所示的那样数数字1、2、3、…数到2010的时候,你数到了你的( )手指上.3. 右图是一个玩具火车轨道,A 点有个变轨开关,可以连接B 或者C ,小圆轨道的周长是1.5米,大圆轨道的周长是3米,开始时,A 连接C ,火车从A 点出发,按照顺时针方向在轨道上移动,同时变轨开关每隔1分钟变换一次轨道连接,若火车的速度是每分钟10米,则火车第10次回到A 点时用了多少分钟?(2010年第十五届华杯赛初赛)在解决周期问题时,关键在于找到周期的长度.只要能找到周期的长度,再用总数除以周期长度,得到的商就是完整的周期的个数,余数就是除去完整周期的部分后剩下的个数.然后细心的数一下,答案自然明了!1. 20102010的个位数字是( ),20112011的个位数字是( ).家庭作业复习总结2. 124×124×124×……×124,共37个124连乘,积的个位数字是几?3. 把分数4/7化成小数后,小数点后第150位上的数字是几?4. 下面的一列数种,123,456,789,101112,131415,……,第二十个数是_______.5.找出下图中第2011列的文字组合学而思培优学而思培优学…智康一对一智康一对一智…专业负责专业负责专业负…6. 在左下表中,在有公共边的两格内的数同时加上1或者同时减去1叫做一次操作,经过有限次操作后由左下表变为右下表,那么右下表中A 处的数是_____.学生对本次课的评价○特别满意 ○满意○一般家长意见及建议家长签字:教学反馈1 0 1 0 1 0 1 0 1A201020102010 2010 2010 2010 2010 2010。

有关流星雨的英语作文

有关流星雨的英语作文标题,The Spectacular Phenomenon of Meteor Showers。

Introduction:Meteor showers, also known as shooting stars or falling stars, have fascinated humanity for centuries. These celestial displays occur when Earth passes through the debris left behind by a comet or asteroid, resulting in a mesmerizing spectacle in the night sky. In this essay, we will delve into the captivating phenomenon of meteor showers, exploring their origins, characteristics, and significance.Origins of Meteor Showers:Meteor showers originate from the remnants of comets or asteroids that orbit the Sun. When these celestial bodies approach the Sun, they release dust, rock, and debris, forming a trail along their path. As Earth orbits the Sun,it intersects these trails at certain times of the year, leading to the occurrence of meteor showers. The debris enters Earth's atmosphere at high speeds, causing friction and heating that produce the luminous streaks we observe as shooting stars.Characteristics of Meteor Showers:Meteor showers exhibit several unique characteristics that distinguish them from other astronomical phenomena. Firstly, they occur at predictable times each year, corresponding to the dates when Earth intersects the debris trails of specific comets or asteroids. For example, the famous Perseid meteor shower occurs annually in August as Earth passes through the debris left by Comet Swift-Tuttle. Secondly, meteor showers typically peak during specific hours of the night, with the number of meteors visible per hour reaching its maximum, known as the zenithal hourly rate (ZHR). Lastly, meteor showers often displaydistinctive radiant points in the sky, where the meteors appear to originate from due to the perspective of Earth's orbit.Significance of Meteor Showers:Beyond their aesthetic appeal, meteor showers hold scientific and cultural significance. From a scientific perspective, studying meteor showers provides valuable insights into the composition and dynamics of comets and asteroids. By analyzing the spectra of meteors and measuring their velocities, scientists can gleaninformation about the materials present in the debris and the conditions of their formation. Furthermore, meteor showers contribute to our understanding of Earth's atmosphere, as the entry of debris particles generates ionization trails that can be studied using radar and other techniques.Culturally, meteor showers have inspired myths, legends, and artistic representations throughout history. In many cultures, shooting stars are seen as omens or symbols of divine intervention, carrying both positive and negative connotations. They have been associated with celestial deities, wishes, and mystical events in various mythologies.Additionally, meteor showers feature prominently in literature, poetry, and art, serving as metaphors for fleeting moments of beauty, human aspirations, and existential reflections.Impact of Light Pollution:Despite their celestial splendor, meteor showers face a growing threat from light pollution, which obscures the visibility of stars and diminishes the viewing experience. Artificial lights from urban areas scatter into the atmosphere, creating a luminous haze that reduces the contrast between the night sky and the fainter meteors. As a result, many people are unable to fully appreciate the beauty of meteor showers, leading to calls for greater efforts to mitigate light pollution through responsible outdoor lighting practices and the designation of dark sky reserves.Conclusion:In conclusion, meteor showers captivate observers withtheir dazzling displays of celestial fireworks, offering a glimpse into the wonders of the universe. From theirorigins in the debris of comets and asteroids to their cultural significance and scientific value, meteor showers continue to intrigue and inspire humanity. By preserving dark skies and fostering appreciation for the natural beauty of the cosmos, we can ensure that future generations will have the opportunity to marvel at the spectacle of shooting stars streaking across the night sky.。

英语口语对话下载:双子座流星雨大爆发

英语口语对话下载:双子座流星雨大爆发While the Gemini meteor shower is scheduled to happen between December 12th and the 16th, tonight the cosmic event will peak allowing viewers to watch shooting stars throughout the night sky.双子座流星雨的预计出现时间为12月13日至16日,今夜这个宇宙盛事将迎来大爆发,观测者们今夜能够大饱眼福,看到流星陨落的美景。

Bill Cooke of the NASA Meteoroid Environment Office said, “Observers with clear skies could see as many as 40 Geminids per hour. Our all-sky network of meteor cameras has captured several early Geminid fireballs. They were so bright, we could see them despite the moonlight.”来自NASA流星体环境研究所的Bill Cooke表示:“如果天气晴好,观测者每小时能看到40颗双子座流星。

我们的全天候流星照相机捕捉到一些早到的双子座流星,它们非常明亮,就算是在月光下也能够看清。

”People who want to see it should look up between 9pm and sunrise tomorrow morning. The Gemini meteor shower is an annual event that happens when “earth runs through a trail of dusty debris that litters the orbit of 3200 Phaethon.” Although, this meteor shower and the reason behind it remains a bit of an enigma. NASA r eports, “Comets vaporizing in hot sunlight naturally produce such debris trails, but rocky asteroids like 3200 Phaethon do not. At least they’re not supposed to. The incongruity has baffled researchers since 1983 when 3200 Phaethon was discovered by NASA’s IRAS satellite.”等待双子座流星雨的观测者能够从今晚的9点到明天凌晨持续注重。

关于流星雨的英文作文初一Title: A Spectacular Phenomenon: Meteor Shower。

Introduction:Meteor showers, a breathtaking celestial event, have captivated the imagination of humanity for centuries. These cosmic displays of shooting stars offer a glimpse into the vastness and wonder of our universe. In this essay, we will delve into the fascinating world of meteor showers.Origin and Composition:Meteor showers occur when the Earth passes through the debris trail left behind by a comet or asteroid. These celestial bodies shed small particles as they orbit the Sun, creating a trail of cosmic dust and debris. When the Earth intersects this debris field, the particles enter our atmosphere at high speeds, causing them to burn up and create the luminous streaks we see as shooting stars.Types of Meteor Showers:There are various meteor showers throughout the year, each associated with a specific comet or asteroid. Some of the most well-known meteor showers include the Perseids, Geminids, and Leonids. The Perseids, for example, occur when the Earth passes through the debris left by the comet Swift-Tuttle, while the Geminids originate from the asteroid 3200 Phaethon.Observing Meteor Showers:Observing a meteor shower is a relatively simple yet rewarding experience. All one needs is a clear, dark sky away from city lights and a comfortable viewing spot. It's best to lie down or sit back in a reclining chair to have a wide field of view overhead. Patience is key, as it may take some time for your eyes to adjust to the darkness and for meteors to streak across the sky. Additionally, meteor showers are often more visible during the pre-dawn hours when the radiant—the point in the sky from which themeteors appear to originate—is highest in the sky.The Beauty of Meteor Showers:The beauty of meteor showers lies not only in the dazzling display of shooting stars but also in the sense of awe and wonder they inspire. There's something humbling about witnessing celestial phenomena that remind us of our place in the cosmos. Meteor showers have inspired artists, poets, and storytellers throughout history, serving as a reminder of the mysterious and enchanting nature of the universe.Scientific Significance:Beyond their aesthetic appeal, meteor showers also hold scientific significance. Studying the composition and behavior of meteoroids can provide valuable insights into the formation and evolution of our solar system. By analyzing the light emitted by meteors as they burn up in the atmosphere, scientists can determine their chemical composition and origin. Furthermore, studying meteorshowers helps scientists better understand the potential hazards posed by near-Earth objects and develop strategies for planetary defense.Conclusion:In conclusion, meteor showers are a mesmerizing celestial phenomenon that never fails to captivate and inspire. Whether viewed as a scientific marvel, a spiritual experience, or simply a moment of wonder, meteor showers remind us of the beauty and mystery of the universe. As we gaze up at the night sky and watch the stars fall, we are reminded of the infinite possibilities that lie beyond our earthly realm.。
