小学英语科普类阅读材料范文Title: The Amazing World of ButterfliesIntroduction:Have you ever stopped to watch a butterfly fluttering from flower to flower? These beautiful insects are not just pretty to look at; they are also fascinating creatures with many hidden secrets. Let's explore the amazing world of butterflies!Body:Tasting with FeetDid you know that butterflies can taste with their feet? It's true! When a butterfly lands on a flower, it uses its special feet, called proboscis, to not only drink nectar but also to taste it before deciding if it's sweet enough. This unique ability helps them find the best flowers for their diet.Colorful ChameleonsChameleons are famous for their ability to changecolors, but did you know it's not just for camouflage? They can also change colors to show their mood or to communicate with other chameleons. Imagine being able to express yourself with just a change in color!The Busy BeeBees are masters of teamwork. They work together to build their hive, collect nectar from flowers, and make honey. Without bees, our world would be a lot less sweet because many fruits and vegetables rely on bees for pollination. Bees are truly important to our ecosystem.The Salmon's JourneySalmon have an incredible journey each year. They swim upstream, against strong currents, to the place where they were born to lay their eggs. It's a long and tiring trip, but it's essential for the survival of their species. Salmon are a testament to the power of instinct and the cycle of life.The Moving PlantSome plants can move! The sensitive plant, alsoknown as the "touch-me-not," closes its leaves when you touch it. This is a defense mechanism to protect itself from being eaten by animals. It's amazing to see how plants have evolved to survive in their environments.Conclusion:The world of butterflies and other creatures is full of wonder and surprises. From tasting with feet to incredible migrations, these animals show us the beauty and complexity of nature. The next time you see a butterfly or any other creature, take a moment to appreciate the amazing world they live in.。

Tablets are really useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn't it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand?Now something like a tablet-shaped but foldable phone is about to become available. In February, South Korean electronics company Samsung and China's Huawei both launched foldable phones, the Galaxy Fold and Huawei Mate X respectively. Mobile phone use has entered the "foldable future", The Verge noted.The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want. Meanwhile, they still fit easily into the pocket. As USA Today noted, they're "the combination of a small tablet and smartphone, all in a single device".The technology could change other devices, too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers. In crowded modem cities, they will help us to maximize available space.In a keynote address, Samsung's senior vice president of mobile product marketing, Justin Denison, called the foldable screen "the foundation for the smartphone of tomorrow". "It's a blank canvas (画布) for us to do something beautiful together." he said.So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of every 10 OLED (二极管) screens produced were imperfect. Today, that 10 percent rate has been improved to between 50 and 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17,500 RMB. That's a price that few people will be able to afford.But if the foldable device isn't going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry analyst told The Verge, "Few are debating if foldable or rollable mobile displays are the future of smartphones; the only question is when and by whom."（1）What can be the best title for the text?A. Screen devices on the market.B. Foldable age is arriving.C. Possible powers of a tablet.D. Foldable screens are imperfect.（2）What can we learn from Justin Denison's words?A. The foldable screen has great potential.B. The Galaxy Fold still has many problems.C. The production of foldable phones will soon increase.D. Companies need to work together to develop foldable phone.（3）What is the problem with foldable phones at the moment?A. They are easy to break.B. They are inconvenient to carry.C. They are not as useful as expected.D. They are unaffordable for most families.（4）What is the author's attitude toward the future of the foldable screen?A. Worried.B. Cautious.C. Positive.D. Unconcerned.【答案】（1）B（2）A（3）D（4）C【解析】【分析】本文是一篇说明文，介绍了“可折叠手机的时代即将到来。

U1-Animal : Lesson 3 - The Polar BearThe polar bear is a very big white bear. We call it the polar bear because it lives inside the Arctic Circle near the North Pole. There are no polar bears at the South Pole.The polar bear lives in the snow and ice. At the North Pole, there is only snow, ice, and water. There is not any land. People cannot see the polar bear in the snow very well because its coat is yellow-white. It has a very warm coat because the weather is cold north of the Arctic Circle.This bear is three meters long, and it weighs 450 kilos (kilograms). It can stand up on its back legs because it has very wide feet. It can use its front legs like arms. The polar bear can swim very well. It can swim 120 kilometers out into the water. It catches fish and sea animals for food. It goes into the sea when it is afraid.Some people want to kill the polar bear for its beautiful white coat. The governments of the United States and Russia say that no one can kill polar bears now. They do not want all of these beautiful animals to die.(200 words)中学生百科英语1-第一单元Animal 1。

初中英语专项阅读——科普小品
英语专项阅读—科普小品AWe know that many animals do not stay in one place. Birds, fish and other animals move from one place to another at a certain time. They move for different reasons: most of them move to find food more easily, but some move to get away from places that are too crowded.When cold weather comes, many birds move to warmer places to find food. Some fishes give birth in warm water and move to cold water to feed. The most famous migration is probably the migration of one kind of fish, which is called “salmon”. This fish is born in fresh water but it travels many miles to salt water. There it spends most of its life. When it is old, it returns to its birthplace in fresh water. Then it gives birth and dies there. In northern Europe, there is a kind of mouse. They leave their mountain home when it becomes too crowded. They move down to the low land. Sometimes they move all the way to the seaside, and many of them are killed when they fall into the sea.Recently, scientists have studied the migration of a kind of lobster(龙虾). Every year, when the season of the bad weather arrives, the lobsters get into a long line and start to walk across the bottom of the ocean. Nobody knows why they do this, and nobody knows where they go.So, sometimes we know why humans and animals m ove from one place to another, but at other times we don’t. Maybe living things just like to travel.Choose the best answer according to the passage.( )1. The main reason why animals move from one place to another is ________.A. to find food more easilyB. that they are afraid of humansC. that they feel too crowdedD. that they don’t like the same place( )2. The salmon is born in ________ and live in ________ most of the time.A. warm water; fresh waterB. cold water; salt waterC. fresh water; salt waterD. warm water; cold water( )3. The underlined word “migration” in the second paragraph means “______” in Chinese.A. 撤退B. 迁徙C. 活动D. 游动( )4. The lobsters usually move when ________.A. the place is crowdedB. winter comesC. the bad weather arrivesD. they give birth ( )5. What’s the main idea of this passage?A. The migration of some animals.B. Why living things like to travel.C. Some interesting fishes.BWhat is life on Pluto(冥王星) like? Is it any different to life on the earth?If you lived on Pluto, you’d have to live 248 earth years to celebrate your first birthday in Pluto years. It takes Pluto much longer to make one lap (circle) around the sun. One Pluto year is the same as 248 earth years.If you weigh 45 kilograms on the earth, you would weigh only 3.6 kilograms on Pluto! Pluto is much smaller than the earth. Gravity(重力) on Pluto is only 8 percent of that on the earth.Remember to bring plenty of clothes if you visit the star. Pluto is cold. Because it is far away from the sun, the temperature on it is about 200 degrees centigrade below zero. It gets even colder as it moves farther from the sun in its orbit(轨道). From Pluto, the sun looks like a dot in the sky, and it is the brightest star you can see. The light from the sun is as bright on Pluto as the light from the full moon on the earth.Complete the table below according to the passage.A 1-5 ACBCAB 1. 248 2. 3.6 kg 3. 100% 4. 200℃below zero5. The light from the sun is as bright on Pluto as the light from the full moon on the earth.CBananas don’t grow on trees. They grow on a thick stalk(茎) that looks just a little like a stalk of corn. The stalk is soft enough to be cut with a knife.It takes about a year before bananas are ready to be picked. Some are as small as fingers. Others are as long and thick as men’s arms. Some banana plants grow as tall as a house — even taller!Not all bananas are eaten as fruit. Some never get sweet, and they are cooked as a kind of vegetable.People in most countries never see a banana until it reaches the store. But if you visited a country where it’s hot and rains a lot all the year, you might see a banana plantation(种植园), a large farm where bananas grow.The tasty fruit doesn’t come from a seed but from a root planted deep in the ground. First a stalk pushes up into the air. Then leaves appear. In the beginning the banana plant grows very fast—sometimes as much as the length of your feet in one night. Soon, sweet-smelling flowers appear, and when their flowers drop off, bananas begin to grow.As they get bigger, bananas start turning up. It looks as if they’re growin g upside down! Bananas are ready to eat when they turn soft and yellow. But they’re picked long before this —when they’re hard and bright green. This is because bananas have to travel many miles before they arrive at a store. On trucks and boats and trains bananas travel all over the world. There are special boats just for bananas and special trains that keep them just cool enough so that they will get ripe while traveling. If bananas are picked when they are ripe, they will spoil(变坏) on the way. Complete the following sentences according to the passage.1. Bananas grow ________ instead of ________.2. You’d better ________ the bananas until they grow for ________.3. Some bananas can ________ a kind of vegetable and some can ________.4. We might visit a banana plantation in a place ________.5. Bananas are usually picked long before they _________.DAre you bored with learning about insects in books? Why not find a few and take a close look by yourself? It’s easy. Insects are everywhere: not just at home or around lights at night, but also in flowers and vegetable gardens, near lakes, parks and in forests.To have fun watching insects, you need:Start by reading books about the insects you’re after. Where can you 1 them? Do they live beside a lake or in trees? When you go out to watch insects, bring along an insect guide 2 pictures with you. A good choice would be “Souvenirs Entomologiques(《昆虫记》)”by Jean Henri Fabre.Dress properly because some insects bite! Don’t 3 trousers and shirts with long sleeves(袖子). Bring a first-aid box.Once you’re ready, an early morning and a nearby park would be a good 4 to start.Insects like to hide in 5 and humid places. Try moving stones and checking flowers, leaves and the soil. Collect insects 6 using a piece of card to pick them up. You may use a magnifier(放大镜) to 7 what insects do. Or, you can put them on a piece of clean paper to look 8 at them. How many legs do they have? What color are they?You also can swing(晃动) your net across the top of the grass. You’ll 9 small bugs (insects) at the end of your net. To catch a bigger bug, 10 the net over the insects and down to the ground. Then raise the end of it 11 the insect can fly to the closed top. Put your bug into a clear bottle, then you can 12 watching it with the magnifier.If you can’t find bugs, try to lure(引诱) them!

This invention was so important that Roentgen won the first Nobel Prize for Physics in 1901. The telephone was invented by Alexander Graham Bell, a doctor and speech teacher. The first phone call was made by Bell in 1876. He got acid(酸) on his pants by accident and wanted his partner, Thomas Watson, to help him. The first words spoken on the telephone were “Mr. Watson, come here! I need you!”Television was invented in 1926 by John Logie Baird, a Scottish inventor. Baird’s television certainly didn't look like a television today! Electronic televisions like the ones we have today were invented by Vladimir Zworykin in the 1920s in the United States.The first computer was built in 1946 by two American engineers, J. Presper Eckert and John W. Mauchly. It was developed for the army, and it was so large that it took up the whole room! Later, in 1971, the “microchip” was invented, and small home computers were first produced for personal use.

·Warm-upHave you ever seen the movie The Lion King? Do you know how lions live in the wild in reality?·Big question to think about while you readHow does the rearing of lion cubs go according to the text?protective of their mates while they are breeding. At the end of the approximately 105-day gestation period, the lioness leaves the pride to go to a sheltered, isolated area to give birth to its litter of two to five cubs. Cubs are born blind. They weigh 1.5 to 2 kilograms, and they have a soft, woolly grayish-yellow-brown coat. The lioness rarely leaves her cubs. When she does, either to hunt or drink, she risks losing them to predators, such as cheetahs, leopards, jackals, or hyenas.At first, the cubs will stay close to their mother as they explore their surroundings. Male cub mortality is high because males are more active and more likely to leave their protected shelter.Cubs accompany their mother on hunting expeditions when they are three to four months old.Cubs will not be able to kill their own prey until they are about two years old. Through early play experiences, the cubs learn how to hunt, crash, leap, and kill their prey.Adolescent males tend to remain near the pride's territory at first and then go off on their own. They will try and join another pride. Male lions display excellent teamwork when threatened by another male wanting to dominate the pride. The typical duration for which a strong group of males is able to defend their pride is two to three years, during which time they father all of the offspring. ( 256 words) ·Reflection questions on what you read1. Why does the lioness rarely leave its cubs?2. What contributes to the high mortality of male cubs?3. How long will it take before cubs are able to kill their own prey? How are they able to do so?4. In the movie The Lion King, Simba finally became the mighty king.

初三阅读理解科普文1.文章题材：最新科技难易度：难建议时间：7 分钟Robots are supposed to run on batteries, right? Well, not all of them.Scientists in England have built a series of small robots that get their energy from deal flies, rotten apples, or sugar. One robot, called Slugbot, was even designed to hunt garden insects for dinner!Well, scientists at the Bristol Robotics Laboratory want to invent robots that can operate for long periods of time in dark, dirty, or dangerous places. Many of those spots, like the seafloor or Antarctica, don’t have electrical sockets (插座). So inventor Chris Melhuish came up with a better idea: build robots that get their energy just like animals do –- by hunting and eating food from their environment.The robots digest their food in a series of stomach—like devices called microbial (微生物) fuel cells that are full of bacterial!The bacteria do the real eating, munching dead flies or other food fed into the fuel cells. As the bacteria eat up the food, they release electrons(电子)，Electrons are charged particles(微粒) that flow to form electricity.One robot, called Ecobot II, could run for 12 days on a diet of eight flies! It seems that after an eight—fly dinner, Ecobot II couldn’t get rid of the leftover“waste”. Melhuish says his team is now working on a new and improved robot, called Ecobot III, which will have a better digestion system.Maybe rest rooms in the future will have singns for bous, girls, and robots.

While there is no agreement among scientists about why we dream, there are many ideas about the different kinds of dreams we have.One common kind of dream is the repeating dream, in which the same story is repeated again and again, often for many months or even years. Some believe these are a sign people have a problem in their life and once that problem is gone then the dream will stop. Others think they are a way to help people remember something very important.Another well-known kind of dream is the nightmare(噩梦). The pictures and stories in such dreams make people very afraid and dreamers usually remember them far more clearly than normal dreams. The cause of such dreams may be seeing something terrifying such as a car accident or some deadly snakes. Others think such dreams may be trying to make a person pay attention to something that is dangerous in their life.Daydreams happen during wake-time when we forget where we are or what we are doing and find ourselves in a made-up story or unreal world. We often daydream when we area doing something that is not interesting or exciting . They help us think about our future.Lucid dreams are the most fun.

But, according to a study, it may be the aroma(香气) rather than the coffee itself that works.Researchers believe that the aroma of roasted coffee beans can be enough to reduce the effects of a poor night’s sleep on the brain.Aroma: Just smelling coffee can help cure(缓解) tiredness better than drinking a cup. They said that chemicals extracted(提取) from coffee and pulled into the air may one day be used as a way of feeling less tired.Scientists in Tsukuba, Japan , kept 16 laboratory rats awake for 24 hours, by keeping them in a cage filled with an inch of water , then put half of them to the smell of roasted coffee.After taking samples of the rats’brains, they found that the smell of coffee boosted the activity of key genes, New Scientist magazine reports today.Professor Yoshinori Masuo, who led the study in Tsukuba, Japan, said that when people drink coffee to stay up all night, just the smell of the coffee could make some of the streets caused by sleeplessness less.He added, ―Is it better for us to smell coffee bean aroma than to drink coffee, or would any other food-related food produce similar effects?

The sun is a massive star that provides light and heat to the planets. The eight planets in our solar system are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.Mercury is the closest planet to the sun. It is very small and has a rocky surface. It has no atmosphere to speak of, which means it is extremely hot during the day and extremely cold at night.Venus is often called Earth's twin because it is similar in size and composition. However, Venus has a thick atmosphere made mostly of carbon dioxide, which causes a runaway greenhouse effect and makes the planet very hot.Earth is the only planet known to support life. It has a moderate climate, a breathable atmosphere, and abundant water.Mars is known as the Red Planet because of its reddish color. It has a thin atmosphere and evidence of past water on its surface.Jupiter is the largest planet in the solar system.

We call a group of fish a "school." They don't study, but they travel together. Dolphins are mammals, not fish, but they swim together in a school.Dolphins talk to the other dolphins in the school. They give information. They tell when they are happy or sad or afraid. They say "Welcome" when a dolphin comes back to the school. They talk when they play.They make a few sounds above water. They make many more sounds under water. People cannot hear these sounds because the sounds are very, very high. Scientists make tapes of the sounds and study them.Sometimes people catch dolphins for a large aquarium. (An aquarium is a zoo for fish.) People can watch the dolphins in a show. Dolphins don't like to be away from their school in an aquarium. They are sad and lonely.There are many stories about dolphins. They help people. Sometimes they save somebody's life.

初二英语科普文章阅读理解25题
初二英语科普文章阅读理解25题1<背景文章>The Earth is like a huge, mysterious ball, and its internal structure is very complex. It consists mainly of three parts: the crust, the mantle, and the core.The crust is the outermost layer of the Earth. It is relatively thin compared to the other parts. The crust is made up of different types of rocks, such as granite and basalt. It is where we live and where all the mountains, plains, and oceans are located. The thickness of the crust varies from place to place. Under the ocean, the crust is much thinner, usually only a few kilometers thick, while on the continents, it can be up to 70 kilometers thick.The mantle is beneath the crust. It is much thicker than the crust. The mantle is mainly composed of solid rock, but it can flow very slowly over a long period of time. This slow movement of the mantle is one of the important forces that cause the movement of the Earth's plates. The temperature and pressure in the mantle are very high. As we go deeper into the mantle, the temperature and pressure keep increasing.The core is at the center of the Earth. It can be divided into two parts: the outer core and the inner core. The outer core is liquid, mainly made up of molten iron and nickel. The movement of the liquid in the outer core isbelieved to be the reason for the Earth's magnetic field. The inner core, on the other hand, is solid. It is also made of iron and nickel, but due to the extremely high pressure in the center of the Earth, it remains in a solid state. Understanding the internal structure of the Earth helps us better understand many natural phenomena, such as earthquakes, volcanic eruptions, and the formation of mountains.1. <问题1>What is the outermost layer of the Earth?A. The mantle.B. The core.C. The crust.D. The ocean floor.答案：C。

Sport injuries肌肉是支撑人体活动的重要部分，我们要小心保护，防止肌肉受伤。
·Warm-upDo you know any kind of sport injuries? Have you suffered from any of them?·Big question to think about while you readWhat are sprains and fractures?Sprains occur when a muscle is pulled too far. The result can be a break or a tear of a ligament. Sprains can sometimes happen as the result of an injury, such as a fall.Sprains can also happen when you do not warm up your muscles before you exercise.A broken bone often occurs as the result of an accident. A broken bone is called a fracture. How can you tell if a bone is broken? The pain in the area is very strong. You cannot move the part that is broken. The part that is broken begins to swell or grow bigger.In most cases, you should not move because a bone may be broken Get someone's help to call an ambulance immediately.You will be taken to a hospital nearby to check whether or not you have a broken bone. To check this, you will normally get an X-ray. An X-ray is a black and white picture of the bones taken with a special machine. It lets a doctor see if a bone is broken. (178 words)·Reflection questions on what you read1. What are the differences between sprains and fractures?2. How can a doctor tell whether there's a broken bone or not?3. What should you do if a sprain occurs?4. Which one do you think is more serious, a sprain or a broken bone?Measuring speed优异的骨骼结构和强健的肌肉使人和动物在运动时拥有较高的速度，下面的文章会告诉你什么动物运动速度最快。
·Warm-upDo you notice that some animals move faster than others? Have you ever thought about why they can move faster?·Big question to think about while you readHow do you define the word "fast"?Content Vocabulary1. distance n. the amount of space between two places or things 距离2. motor n. the basic unit for measuring length 米3. kilometer n. a unit for measuring distance, equal to 1,000 meters 公里4. athlete n. someone who competes in sports competitions, especially running,jumping, and throwing 运动员5. compare v. to examine and note the similarities or differences of 比较The movements of our bodies help us to go from one place to another. For example, when you go to school, you can walk, run,ride a bike, or ride in a car or a bus. You must cover a certain distance. Distance is the amount of space between two places.Did you know that the distance from one place to another can be measured in meters? But if you need to measure distances that are longer than 1,000 meters, then it is usual to measure them in kilometers.Sometimes we measure the time it takes to travel a certain distance. This is called speed. Speed is measured in hours, minutes, and seconds.When an athlete covers a distance of 100 meters in ten seconds, we know that the athlete can run very fast. It takes an average person around twenty seconds to run 100 meters. The athlete runs the distance much faster than the average person. How fast can you run 100 meters?Which are the fastest animals?Animals move at different speeds. Some animals move faster than others. Compares how fast or slow different animals move.Which athletes are the fastest?Athletes spend many hours in training and practice in different sports. Coaches teach athletes how to improve their speed and strength. As a result, athletes develop strong bodies and muscles.Some athletes move very fast. They take part in races to see who is the fastest at certain sports. The Olympic Games is the largest sports competition in the world. (254 words)·Reflection questions on what you read1. How can we calculate a moving object's speed?2. What units of measurement do people use to measure distance?3. What units of measurement do people use to measure speed?4. Why do athletes have to spend many hours in training and practice in different sports?5. Please name at least 3 Olympics sports where athletes take part in to compete for speed.The locomotive system人体有着复杂的组织结构，正因为这样，我们能够行走、奔跑、跳跃。
下面让我们一起来探索其中的奥妙吧！·Warm-upHow much do you know about your body? Do you know what's happening in your body when you're walking, jumping and running?·Big question to think about while you readWhat exactly is the locomotive system?We have learned how receptors on our sense organs send messages to the brain, which then responds to the signals. The response from the brain can be a movement of the body.Most of the movements of our bodies occur because we want them to happen. These are called voluntary movements. If we want to kick a ball, we have to think about doing it. Our brain receives the message, and immediately our foot kicks the ball.Other movements are called involuntary3 movements. Certain muscles in our bodies work without us having to think about them. For example, the muscles that move food through our digestive system4 are involuntary. They work even while we are sleeping.Bones and musclesBones make up the skeleton and support the body. But bones do not move on their own. They need muscles to move. Muscles move every part of the body, such as the head, fingers, legs, and toes, and even our eyes and tongue.Muscles are made out of many stretchy, elastic cells and fibers. Muscles function like rubber bands that stretch and relax in the body.Muscles work in pairs. One muscle pulls the bone forward, and another muscle pulls the bone back. When one muscle is working (contracting), the other muscle is relaxing. Your muscle pairs work together to move.The place where one bone joins another is called a joint6. Joints allow movement and give the skeleton its ability to bend, twist, and turn.Tissues called ligaments hold bones together at joints. Bones, muscles, and ligaments make up the locomotive system. This system gives the body its form and allows it to move. (274 words)·Reflection questions on what you readl. What's the difference between voluntary and involuntary movements?2. Please give 3 more examples of involuntary movements.3. How do the muscles help you to move?4. What's a joint? Please give an example.5. There are many athletes who suffer from ligament injuries and cannot take part incompetitions anymore. What will happen if there is a broken ligament?The ear and the hearing听觉是仅次于视觉的重要感官通道，它在人的生活中起着重要作用。
