　　高中英语作文：科学与生活 1

　　Science enables human beings to progress rapidly and lead a better life. For example, Edisons invention of the light bulb brought our gloomy life to the end and created a bright world for us. Another case in point is Watts discovery of the steam engine, which triggered the industrial revolution in the western countries, and later all over the world.

　　Meanwhile, sometimes science does have some side effects. A good illustration of this is atomic energy, which can destroy human beings completdy when used in nuclear weapons.

　　Anyhow, it is men who develop science. And science, in turn, will do us good in general. As for its side effects, I believe human beings will be rational enough to avoid them or keep them under control.

　　Science and technology have been bringing human beings tremendous benefits. Thanks to science and technology, we now live comfortably and conveniently in houses furnished with air conditioners, refrigerators, washing machines and televisions etc. Thanks to science and technology, we can eat fresh vegetables att the year round. Thanks to science and technology, we can travel tong distances in the fraction of a second on planes, trains and cars. Thanks to science and technology, we wear clothes with synthetic materials which can not easily be worn out.

　　However, science and technology have atso brought us a tot of disasters. First, because of the many breakthroughs in the field of medicine, people are now living much longer than they used to. As a result, the population of the world is increasing, causing tots of problems. Second, because of the development of industry, tots of the wastes from factories pour into the air and rivers, causing pollution of att kinds. Third, some terrorists are using science and technology against mankind. They use biological, chemical and unclear weapons to threaten world peace...

　　So its urgent that we find ways to solve these problems. But we should not stop the development of science and technology because of these disasters they bring, just as we should not give up eating for fear of choking. In addition, we should make some rules to regulate our actions. As long as we use science and technology in a proper way, they may bring us even more benefits.

　　human life can not continue without science and technology. for many years, human society has developed with the advance of science and technology while the development of science and technology has in turn brought the process to mankind. so the life we are living now is more civilized than that of our fore fathers.

　　the development of science and technology have brought about many changes in peoples life. for eample, the invention of television and space rocket have opened a new era for mankind. through the use of tv people can hear the sound and learn the events happening thousands of miles away. owing to the invention of spaceship and rocket, the dream of mans landing on the moon has now come true.

　　science and technology also play an important role in our socialist construction. we may say, our socialist construction is just like a skyscraper, while science and technology are its base. without the base, the skyscraper cant be built. therefore, we should try our best to contribute to the development of science and technology so as to provide a more solid base to build our country.

　　Dad bought a robot vacuum cleaner. From now on, the cleaning of Grandpas house will be left to you!

　　When I opened the package, a disc-shaped creature appeared before my eyes. It is all black, and there are several small parts lying on the side! Dad followed the instructions and put the small parts on one by one. Press the switch again, and a beautiful piece of music wafts out. Then, an aunts voice softly sounded: "Master, please give me a name!" Dad looked at me and said, "This task is for you!" I held my chin for a moment and thought, "Little disc! Lets call it a little disc!"

　　I put the little disk on the ground. Whisk! Baa! Baa! He waved his little brush and began to work! Oh, no! The discs going to hit the wall! I was worried. I was about to stop it. Why, it stopped just one centimeter from the wall. Turn a corner and continue to feel your way along the wall. Boy, do you have eyes?

　　Halfway there, the little disk stopped again. A small red light on the side of the switch flashed. Its not dead, is it? I saw the small disc slowly turned, and then went straight towards the electric seat. Align with the base and climb steadily. "Start charging! Start charging!" The little disk is so smart, and it knows how to charge itself!

　　Dad read the instructions, the first charge should be full for four hours. Wow, little disc, looks like youre a big eater after all!

　　On Saturday, my mother bought a purple and blue flower in a vase at home, put some water, and after a while, the water changed color.

　　At first, only some purple, like a light veil, spread in the water; After a few hours, the water is like a floating purple cloud, there is no ripple on the water, but the purple cloud has always been floating again; After that, the water seems to be divided into two pieces, the upper third is colorless water, the lower head is purple blue pigment water, no longer like yarn, such as fiber cloud, more like a piece of colored ice; Eventually, the whole bottle turned purplish-blue.

　　I wonder how water can change color for no reason. Is there something wrong with this flower? Suddenly, I remembered an experiment I read in a book: put a pure white or light colored flower in colored water, and as the flower absorbs the water, the petals will gradually change to that color. This purple-blue flower probably came from the same way! I took the flower out and was surprised to find that although its branch surface was still green, the core inside it was already purple and blue. After a few days, as if to verify my guess, the water is more pure blue day by day, but the color of the petals is lighter day by day.

　　Every bit of life is inseparable from science, just as water becomes purple and blue.

　　Today, Teacher Li brought us some small pieces of paper and also brought a ruler. Teacher Li said mysteriously, "This ordinary ruler has magic power to suck up the small pieces of paper I just gave you." We were skeptical, and in order to prove that what Teacher Li said was correct, we all began to try.

　　I slowly put the ruler close to the small paper, but the small paper is still not sucked up, the teacher let us wipe the ruler clean, and then to suck can not suck up, at this moment I began to doubt what the teacher said.

　　I thought, "Is Teacher Li lying to us?" Why do I suck it? It doesnt even come up.

　　The teacher said: "I teach you a way, you put the ruler on the clothes back and forth friction, you can suck up small pieces of paper."

　　I put the ruler in my clothes hard back and forth friction, placed on the small paper above, at this time, a miracle happened, the small paper shook a bit, immediately stuck on the ruler, I shouted happily: "I suck up!" Im inhaling!"

　　Why is that? Originally rubbing the ruler back and forth against the clothes would produce static electricity, which would suck up the slightest thing, like the patter of clothes when you take them off at night. Your hair gets caught in the TV when you walk past it......

　　As long as we observe carefully, we will find a lot of science.

　　The sun was mercilessly releasing its own heat, and it was so hot I couldnt breathe. So, I plan to go to the grocery store to buy ice bars to cool down the summer.

　　Arriving at the grocery store, I went straight to the freezer, but I actually saw the thick quilt pressed on the freezer. I thought: such a hot day still put the quilt on the freezer, it must be completely melted. When I thought about it, I went to "help" take the quilt down.

　　At this time, the shop owner came back, saw me "murder", hurriedly said to me: "What are you doing! Put it down!" Facing the menacing boss, I cleverly put down the quilt and stood aside waiting for the scolding. "What are you doing? The ice bars are melting!" I was very confused, I was helping him, why did he still scold me? "Why, when it is covered with a quilt, it will melt!" I said defiantly. After listening to the words, the boss said to me: "I do this to prevent the hot air outside from flowing into it, which is to keep the cold!"

　　When I heard this, I was very ashamed and said to my boss, "Sorry, I know I made a mistake." The boss was so helpless that he had to let me go, but he warned me not to do anything stupid in the future, and I nodded and agreed.

　　A case to buy ice bars, let me understand a lot of knowledge, but also let me know the scientific truth in life, everywhere.

　　Hot summer, the sun baked the earth, the road seems to have a warm current, the scene became hazy. The sweat on the head is like a mountain spring in general, endless stream, sweat from the head down, the line of sight has become very blurred...

　　At this time, the neighbor came out to water the plants, but he was stingy to the cactus water a little, I was curious, with doubts to ask my mother: "Mom, why the neighbors uncle in such hot weather, but only to the cactus water a small amount of it?" Mother did not answer me, let me search for myself. I couldnt wait to turn on the computer and search for the reason.

　　Originally: cactus originated in tropical and subtropical arid areas with little rain, in the harsh environment of hot and dry, exercise a pair of steel and iron body, and become a winner in the elimination of heaven. Its leaves become the smallest needle-like, but the stem becomes a fleshy leaf, which takes the place of the leaves for photosynthesis. The outer layer of this abnormal stem is a grating tissue like a nail stomach, and the outer skin is smooth and dark green, and the inside of the stem is a spongy tissue rich in glia, which is a reservoir of water and nutrients for the dry season. The pores of the cactus are hidden in the hairs on the base of the acupuncture, and the valve is closed during the high temperature during the day to prevent the water in the body from evaporating, so the cactus does not need to pour too much water.

　　After reading the information, I had an Epiphany: the young pioneers are the expectations of the motherland, we must learn science, for the motherland more innovative spirit!

　　A few days ago, I went to play with my relatives, saw a few small partners playing together, I saw them holding a magnifying glass, facing the sun just for a while, the white paper under the magnifying glass actually suddenly burned up! Oh, my eyes light up, what on earth is going on? Ive been thinking about it.

　　Today, I am idle and bored, just want to find something to do, what? Suddenly, I remembered that little experiment from that day.

　　First, I found a piece of paper, a magnifying glass and a bottle of glue as my friend told me. First put the white paper on the sunny wall, and then use a magnifying glass to shine at the sun, who knows that in the end it is nothing.

　　A few days later, when it was very hot, I thought of the experiment again, and after gathering the materials together, I went to do the experiment again. This time I held the center point of the magnifying glass to the sun, and after a while, the white paper burst into flames. I danced with joy.

　　After the experiment, I thought: if there is a sun every day, we can not use this magnifying glass to light the fire? What would that look like? So why did scientists invent lighters and matches? I just need a magnifying glass. I went to ask my mother with questions, and her mother said: "Yes, then if it is rainy, we cant do it?" Your magnifying glass only works on sunny days." It dawned on me!

　　Through this experiment I know: there are many mysteries in life, as long as we do a life of people, we will be able to find many hidden in the mystery of life!

　　Do you know what glue is? By the way, glue is a sticky liquid that sticks to things. However, you must not know what "magic glue" is! In fact, its an invisible glue.

　　Jingling is in class. At this time, teacher Kong smiled and walked on the platform. The teacher said: "Today, I will show you a magic trick." The students were all excited. The teacher first borrowed two ancient poetry books of the same thickness from Wang Yitong and He Yisong, and then made a move to turn the book and showed that there was nothing in the book. The teacher mysteriously took out a bottle of glue from his pocket, and then put the two books together and "stuck" them with invisible glue. Look, she opened a page of a book and pretended to put a little glue on it. Then, I glued a page of another book onto it several times, and finally it was finished.

　　The teacher first called a single heart Ying to open the two books, but she spent nine ox two tigers effort, also did not open the book. The teacher called me and Xue Jingliang again, and the students applauded and shouted for our two big male classmates. The two of us went all out, tried our best, and still couldnt pull it apart.

　　At this time, the teacher explained: "This is friction at work, friction is a force that impedes the movement of objects, there is friction between each page, so it can not be pulled open." Listening to the teachers words, the students suddenly saw light.

　　Science comes from life, life also has the shadow of science. Even the lessons in science class are relevant to us.

　　Take a look with me first: We are all too familiar with the nylon tower buckle, that is, the hook, was an engineer after a walk, found and observed the needle on his dog, after a long research and invention.

　　Do you remember when we learned in science class that opposites attract magnets? It seems to be of no use, but an older sister in Wujiashan, Wuhan, when she was in the sixth grade, because it was inconvenient to hold soap with wet hands, she used this principle, repeated trials, and designed a non-slip soap that was easy to carry, and thus won a national patent.

　　For learning science, some students complain that it is not practical, I thought so before, but after reading the story of this sister, I found that the magic of science is not confined to a certain place, it can be from one knowledge point, to many places, even if it is just to make jelly, you can also think about whether the AGAR used in homemade jelly is made of animals or plants. There is always science in life.

　　In the future, science may be used more widely, from a rocket plane to a smart chair, bit by bit, everywhere. So we all have to study hard, study hard, in the new era of scientific and technological innovation personnel, there may be you!

　　When I was 7 years old, I saw a spent and lit quartz clock in the middle of my grandfathers living room. "Why does the second hand of the quartz clock stop at the number 9?" Why keep going to 1, 2, 3, or any other number? Maybe it is in the quartz clock brother, just no power, the second hand just stopped on the 9 it!" I looked at the quartz clock hanging on the wall and said to myself. "What are you thinking, granddaughter? So entranced?" Grandpa came up and asked, "Lets go to my aunts house." "HMM."

　　Came to the old aunts house, grandpa and old aunt and other elders to talk. I will walk around in my old aunts house, and I saw a quartz clock with no electricity in the warehouse, and its second hand is also stopped on the number "9", why is this? So I ran into the living room to ask Grandpa. Grandpa told me, "Granddaughter, this quartz clock is hanging on the wall, and when its battery runs out and it stops moving, this second hand tends to stop at the" 9 "position on the dial. This is because the second hand receives the most resistance at the "9" position. Therefore, the second hand stops on the number "9" and stops on the other numbers, okay?" "Ouch! So it is!" It dawned on me.

　　There is science everywhere in life, as long as we pay attention to observe, we will find many treasures - to benefit from a lifetime of scientific knowledge.

　　高中英语作文：科学与生活 17

　　I find that in our daily life, we are surrounded by all kinds of scientific trivia:

　　When I help my mother to carry things, I found that if the bag handle is very thin, my hand will be strangled to break, but if I take out gloves to cushion the thin handle, my hand will be much more comfortable, this is because the force surface is larger, the force on a single place is smaller, it does not feel so uncomfortable.

　　When I used the water gun to water the flowers on the terrace, since the water gun in my home is 15 meters long, and the furthest big mulberry tree is at least 20 meters away from the tap, I began to study how to shoot water to the position of the mulberry tree, so that it can drink water. I found that when I held the water gun up to a 45 degree Angle, I was able to shoot the water the farthest, and when it was less than or greater than a 45 degree Angle, the water didnt shoot as far, which my dad told me was the physical equivalent of "45 degrees, the longest parabola." Ha, although I have not taken a physics class, I have learned physics in life!

　　When I put the hot water bag in winter, if I put the hot water directly on the lid, the whole hot water bag will bulge, there will be a lot of air in it, so every time I have to squeeze out some air inside and then screw on the lid. This is the principle of "heat expands and cold contracts" : when the air is heated, it expands to make the hot water bag bulging.

　　As long as we have a pair of good at discovering eyes and good at thinking brain, we can learn a lot of scientific knowledge in ordinary life!

　　高中英语作文：科学与生活 18

　　Do you believe eggs float in water? Many people listen, will say of course not, how can the egg float in the water? I didnt believe it before, but after my own experiment I believed it.

　　It was a Sunday, mom and dad because of something all went out, home only I a person, I wrote the homework early, so I was in the living room to read "100,000 why" this book, "hey." I suddenly saw that the egg could float, and I was skeptical, so I was going to try it out for myself. I brought a bowl and an egg, then a bag of salt from the kitchen and put it on the table.

　　The experiment began, I first went to the kitchen to take a little water in the bowl, and then put the egg in, the egg really sank, after, I sprinkled a little salt into, miracle appeared, the egg actually floated up, I was very surprised, thought: why did the egg touch the salt will float to the surface of the water? I went to read a book, and the book wrote: Because when the water becomes the necessary concentration of salt water, the egg is lighter than the same volume of salt water, and the buoyancy force it receives is greater than its own force, so the egg can float on the water in the salt water. I read the book and finally realized my mistake in understanding this.

　　After this incident, I understand: a person can not arbitrarily determine the result of a thing, we have to personally experiment to determine it, which is essential in science.

　　Recently I read "One hundred thousand why - Life fun common sense", this book tells a lot of interesting and practical scientific knowledge in life, really do not know, a look startled. In our daily life, clothing, food, shelter, travel, everything is inseparable from science, if you do not know some necessary common sense of life, may bring harm to our body.

　　For example, some people usually take medicine with tea, some children like to sleep with "hair toys", and some people like to Wolf down their meals... These situations can be seen everywhere in life, and they seem to be no big deal, but they will affect peoples health.

　　Why cant you take medicine with tea? Originally, tea contains tannic acid and theophylline, which can combine with a variety of metal ions in some drugs, produce precipitation, affect the absorption of drugs, and reduce the efficacy of drugs, so it can not be taken with tea.

　　What are the dangers of sleeping with a "hairy toy"? Therefore, it is recommended that children do not hold hair toys when they sleep.

　　Life contains a wealth of scientific knowledge, we should participate in more social practice activities, learn from life, learn scientific life, so that our life will be happier!

　　Today, we saw the works of the Science and Technology festival - disposable paper cup transformation, in the exhibition hall there are various, a variety of handmade works, these can be our own creation oh! The first thing that catches your eye is a large round ball in the middle, which is assembled with disposable paper cups.

　　On the right table I saw a "rocket", I think the workmanship is very fine, the look is also very similar, I look carefully, this is not my deskmates work? Im so happy to hear that he won the first prize! I looked to the other side and saw a beautiful "wind chime" with a lot of small decorations. I think they really have a lot of imagination. Aww... A set of dining table, very beautiful, the table is also placed some eat "snacks". I think this must be done by a smart student. Then saw a creative - cake low tuo do "animal" playground, see how happy they play! We take a closer look, the original best works are completed by first-grade students, then the students immediately talked about it, some said: "This is the parents to help." Some said, "These look like they were made by a sixth grader." Another said: "They are doing better than us, really impressive!" At this time, my heart silently thought: Next time, I also want to seriously do a good job of works for awards.

　　I felt deeply about this activity. Although my work was not selected, my work was exhibited in the class, and I was also very pleased, because I had gained happiness in the production process! Thank you for organizing this event!

　　People think that science must be important and great, but the existence of science can be found little by little in life.

　　One sunny afternoon, I walked on the way to the market, saw the pine trees held their heads up, the green leaves floating in the wind, like a tall giant defending the motherland. I think: spring pines really lush, do not know its fate in winter.

　　Unconsciously, winter came, and I once again walked on this road. I looked both ways, huh? Now is the winter when the north wind whistles, how can the pines and cypresses still be green and green? A question left a big question mark in my mind, and my curiosity was immediately aroused.

　　Back home, I immediately opened my "good helper" and "good teacher" —— "100,000 why" checked up, oh!

　　Because the leaves of the pine and cypress are needle-shaped, not much water can escape from the leaves. In addition, the surface of the pine leaves is coated with a wax-like thing to protect the leaves. In the cold and dry winter, the green pine and cypress are not afraid of the cold, and the water in the tree is more sufficient, so the pine and cypress are also green in the winter.

　　The answer turned out to be so, the question mark in my heart was erased, and a satisfactory full stop was drawn.

　　In fact, there is science everywhere in life, as long as you observe carefully and are good at finding, one scientific mystery after another will be unveiled for you.

　　One evening, on my way home from school, I looked up and saw a cat climbing to the roof of a three-story building. It in the above a jump to play, accidentally stepped on an empty, fell down from above, just in front of me, "meow meow" called a few times, from the window into the hosts house, undamaged appearance. I look stunned, as the saying goes, "the cat has nine lives", today I am learned.

　　Back home, I consulted and consulted various information, and finally understood the truth. Originally, cats are good at climbing and jumping animals, and the balance of various organs in the body is better than that of other animals. When a cat falls from a height, it can restore its balance in a few tenths of a second. Because, when it falls from a high place, its eyes feel it first, and then it immediately reports to the "supreme command" brain, which quickly makes a judgment and orders all parts of the body to take corresponding measures. So, it made everything ready to land while it was still far from the ground.

　　Then you may ask, "Even so, why dont cats break their feet?" Well, its all thanks to the well-developed pads under the cats feet. The pad is thick, soft, elastic, and doesnt make a sound when you walk. When a cat falls from a high altitude, the soft meat pad can protect it from the vibration of the ground.

　　After understanding the characteristics of cats, the saying "cats have nine lives" is not difficult to understand.

　　Today, I inadvertently saw that the thick "100,000 Why" has been covered with dust, this book is the kindergarten teacher sent me, so far have not seen several times. So I took down my book and read it carefully. As soon as I opened it, I was fascinated by it. "What is Nanotechnology", "What is GPS for", "Why can Remote control"...

　　These articles made me understand a lot of scientific knowledge and broadened my horizon. A lot of scientific puzzles that we think are hard to solve are solved here. Many students think that science and technology is far away from us, learning is useless, so they never care about this aspect, but in fact they are wrong, in fact, science and technology is around us, it is closely related to our lives.

　　In science class, the science teacher came in with a sound tube in his hand. In class, the science teacher asked the two of us to talk to each other. The other person said something, and I heard it very clearly. After school, I quickly finished my homework, and then began to make the voice cone.

　　The material for the voice tube is only two paper tubes, two small discs and a piece of wool. I divided the paper tubes into two and covered one side of the two tubes with small pieces of paper. Stick the small round piece with adhesive paper, and then use a needle to put the small round piece through a small hole, and put the wool through the hole of the small round piece to make a sound tube. I tried it. No sound. Failed.

　　I couldnt bear it. I did it again. This time, I very carefully divided a paper into two, made a small hole in each of the small round pieces, pasted the small round pieces with transparent glue, and then threaded the wool into it, and then tied a knot on one end of the rope, and tied a knot on the other end of the rope, and then tied a knot on the other end of the rope. I tried it, and I succeeded. Why does the sound tube carry sound? I checked it with my mothers mobile phone, and it turned out that it was because the solid voice transmission after straightening reduced the sound in the air, so it could be heard.

　　There are wonderful things in life, waiting to be discovered and explored.

The teacher looked at us with a puzzled expression. "In life," he continued, "what things expand when heat and contract when cold?" Everyone was speechless. The teacher went on to say: "The road, the floor need to leave a small seam, in order to break the object when it is cold and hot." Hearing the teachers words, we suddenly saw the light.
