acid rain酸雨英文版

Acid rainChristine Acid rain is harmful water pollution. It affects human, animals and buildings or sculptures. Because of the serious problems, human is trying to prevent the harm. Many countries arranged some rules for them, such as some new science on industry. Many factories use the new science and reduce the sulfur dioxide.Acid rain hurts human skin, when the acid rain drops the skin, hurts the skin likes burning the skin. So in acid areas, when the weather is raining, then people must hold umbrellas, because of the acid rain then, the umbrella broken speed is very faster than others in the common areas.Acid area destroys forests and pollutes water, the trees absorb the acid water, then they will fall leaves, and then they will die soon. Also some aquatic animals died because they can’t adapt to the environment.Old buildings were built by lime, when acid rain contacts them, and then they will corrode them. And in a short time, maybe we can’t see their new appearance again. The old buildings and sculptures record history and symbolize art, they have very important value. If they disappear, then it is our human’s damage.The cause of acid rain mostly is human’s activities, the acid rain’s harmful effect very wide. So I hope we can protect our environment in vehicle or use scientific ways to change our behaviors to help ourselves.Such as: we can take bicycle or just walk, they can keep our health. Also in industry, we also can use advanced science to reduce our human’s activities pollution and keep our beautiful Earth.I think we can do more for out beautiful nature environment and our human’s living area in the future.。

Acid Rain>Essay On Acid Rain:Acid Rain is composed of highly acidic water droplets due to air emissions, specifically the disproportionate levels of sulphur and Nitrogen emitted by vehicles and manufacturing processes. Often called acid rain as this concept contains many types of acidic precipitation.The acidic discharge takes place in two ways: wet and dry. The pH value of normal rainwater is around 5.7, giving it an acidic nature.Long And Short Essays On Acid Rain for Students and Kids In EnglishWe provide students with essay samples on an extended essay of 500 words and a short essay of 150 words on the topic Acid Rain.Long Essay On Acid Rain 500 Words In EnglishLong Essay on Acid Rain is helpful to students of classes 7, 8, 9, 10, 11 and 12.As the name suggests, acid rain can be said to be the precipitation of acid in the form of rain in the most straightforward manner. Whenatmospheric pollutants like oxides of Nitrogen and sulphur react with rainwater and are available with the rain, this leads to Acid Rain.The acidic deposition takes place in two different ways: wet and dry. Wet sediments are any form of precipitation that removes acids from the atmosphere and places them on the earth’s surface. In the absence of precipitation, dry deposition of polluting particles and gases sticks to the ground through dust and smoke.The causes of acid precipitation are Sulphur and Nitrogen particles which get mixed with the wet components of rain. Sulphur and Nitrogenparticles which get mixed with water are found in two ways either human-made because the emissions are given out from industries or by natural causes like how a lightning strike within the atmosphere releases from volcanic eruptions.According to the Royal Society of Chemistry, which considers him the “father of acid rain,” the word “acid rain” was invented by Scottish chemist Robert Angus Smith in 1852. Smith selected on the name while studying rainwater chemistry near industrial towns in England and Scotland.Even though it is clean, the regular clean water we experience, i.e. water and CO2, react together to make weak carbonic acid which virtually by itself isn’t overly harmful. The pH value of normal rainwater is around 5.7, giving it an acidic nature. The oxides of Nitrogen and sulphur are blown away by the wind along with the dust particle. They choose the earth’s surface after coming down within the sort of precipitation. Acid rain is a byproduct of human activities that emit the nitrogen and sulphur oxides within the atmosphere—such as burning fossil fuels and unethical waste emission disposal techniques.Sulphur dioxide and nitrogen dioxide undergo oxidation, and then they react with water resulting in the formation of the sulphuric acid and nitric acid, respectively.Acid rain is extremely harmful to agriculture, plants, and animals. It washes away all nutrients which are required for the expansion and survival of plants. Acid precipitation affects agriculture by the way how it alters the composition of the soil. It causes respiratory issues in animals and humans. When acid rain falls and flows into rivers and ponds, it affects the aquatic ecosystem. As it alters the chemicalcomposition of the water, to make which is harmful to the marine ecosystem to survive and causes pollution. Acid precipitation also causes water pipes’ corrosion, which further leads to leaching of heavy metals like iron, lead and copper into the beverage. It damages the buildings and monument made from stones and metals.The only precaution that we will take against acid precipitation has a check at the emission of oxides of Nitrogen and sulphur. Being responsible citizens, one should remember the harmful effects they cause and the industriesthat give out Nitrogen and sulphur compound wastes unethically.Short Essay On Acid Rain 150 Words In EnglishShort Essay on Acid Rain is helpful to students of classes 1, 2, 3, 4, 5 and 6.Acid rain is caused by a reaction that begins when compounds like sulphur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to make more acidic pollutants called acid precipitation.The ecological consequences of acid precipitation are seen most strongly in marine habitats, like streams, lakes and marshes where fish and other wildlife can be toxic. Acidic rainwater can leach aluminium from soil clay particles because it flows through the soil then floods into streams and lakes.Sulphur dioxide and oxide and therefore the principal chemicals for acid precipitation. It also can influence human since the acid goes into fruits, vegetables and animals. In other words, we will get sick if acid precipitation doesn’t stopand that we eat those things. Generally, the acid precipitation affects man, but indirectly.10 Lines On Acid Rain Essay In EnglishAcid rain is formed by highly acidic water droplets due to air emissions.Sulfur dioxide and oxide and therefore the principal chemicals for acid rain.The only precaution that we will take against acid rain has a check at the emission of oxides of Nitrogen and sulphur.Acid precipitation affects man.It also can influence humans since the acid goes into fruits, vegetables and animals.Acid rain is extremely harmful to agriculture, plants, and animals.The pH value of normal rainwater is around 5.7, giving it an acidic nature.Acid rain also causes the corrosion of water pipes.The acidic deposition takes place in two different ways: wet and dry.Acid rain is a byproduct of human activities. >FAQ’s on Acid Rain EssayQuestion 1.What is going to happen if we don’t stop acid rain?Answer:Acid Rain influences human since the acid goes into fruits, vegetables and animals.

九年级英语任务型阅读期末专项练习AEvery time we turn on the TV or take a ride in a car, we could be adding to a problem called acid rain(酸雨). In this article, we’ll learn something important about acid rain.The formation of acid rainWhen people use fuels (燃料), such as coal and gasoline(汽油), poisonous gases are given off. When these gases come together with rain, acid rain forms. Many power stations burn fuels in order to create the electricity(电) that we use in our homes and offices every day. Cars and trucks also send these gases into the air when they burn gasoline. When rain meets these gases, harmful things called acids form. This is acid rain.The harm of acid rainAcid rain destroys everything that it touches. It poisons our rivers, ponds and lakes and oceans along with the life in them. It pollutes our soils and crops, harm trees, and can even kill fish and plants. Acid rain also eats away at our buildings.The prevention of acid rainWe need to reduce and even stop the pollution that gets into our air. Turn off lights, televisions and other electrical appliances(电器) if we are not using them. Walk and take a bike whenever possible. If we are travelling a long distance, take a bus or train to save fuel.As research shows, acid rain harms our environment. But people everywhere can take small steps now to help protect our environment for future generations.Whenever we use electricity or drive our cars we may add something bad to the air around us. And even worse, we may cause a terrible problem—acid rain.The formation of acid rain When fuels, such as coal and gasoline are burnt, harmful gases are sent into the air.When these gases 1 with rain, acid rain forms.The harm of acid rain Acid rain is greatly 2 to the environment. It makes our rivers, ponds andlakes and oceans dirty and 3 the death of fish and plants. And it cancorrode (腐蚀) the buildings we live in.The prevention of acid rain Trying to prevent the pollution that gets into the air is 4 . Keep the electrical appliances off while they are not in use. We can also use different ways of traffic to make less use of fuels.Research tells us that acid rain harms our environment. So people around the world can take small stepsnow to make a 5 to our kids.BWe often see top students around us and everyone knows about them. Let us take Jenny as an example. She is the monitor of our class. She spends a lot of time working for our class. But she still gets good grades in all subjects. How do students like Jenny do that? When I asked her, she said, “Hard work is not the whole story. It’s not how long you sit at the desk with your books open. It’ s what you do while you are sitting.” Indeed, we can see many top students spend fewer hours on their studies than their classmates. Jenny gave me some valuable suggestions.If your math teacher assigns(分派) five problems you should do six. If your Chinese teacher assigns eight pages of reading, you should read nine. The more you practice, the more you learn.Studying is a matter of personal preference(偏爱), so choose the way you are most comfortable with. Some people like working at night when the house is quiet, while others like doing their work early in the morning. Still others like studying as soon as they arrive home from school while the work is fresh in their minds. No matter which way you use, try to do your best.Studying is your business and business comes before entertainment(娱乐). When you are studying, phone calls should go unanswered, TV shows unwatched, snacks uneaten. Studying is the only thing in your mind. Nothing can pull you away from what you are studying.Studying is like eating. You chew(咀嚼) it one bite at a time. You can plan what to do today, but don’t do too much. When you can’t finish the work you planned to do, you may lose confidence. On the other hand, you will not study well without a good plan. It all depends on how you arrange your time.The students who hand in a clearly written paper is already half way to an A. Neat(工整的) papers are likely to get higher marks than sloppy(被泼水弄湿的) ones. When you write neatly and do your work carefully, the thoughts in your mind are clear. You are able to make fewer mistakes.How to improve your studiesPassage outline Supporting detailsDo more than 1 your teacher asks you toDo more than you are askedBecause practice makes you learn more.◆ Some people like working on a quiet night,Choose 2 wayswhile others like doing their work early in the morning. Some people likestudying their lessons upon their arriving home from school. Put study before entertainment Fix all your 3 on what you are studying.Plan your time well ◆ Don’t try to do much at a time.◆ 4 in finishing your task as planned will make you less confident.◆ On the other hand, you will not study well without a good plan.Keep your papers neat◆ Clearly-written papers are more likely to get better marks than sloppy ones.◆ Besides, some mistakes can be 5 .CWhenever we meet with difficulty or failure (失败), teachers, parents or others often say to us "Never give up." These can be encou raging words. A person should believe in himself and keep trying to be successful no matter how many times he fails. Therefore, I believe that we should never give up.One reason is that if we give up too easily, we will seldom achieve anything. It is not unusual for us to fail in something new, so we should try again. Besides, if we always give up when we fail , we will not be able to develop new skills and grow.Another reason is that we can learn from our mistakes so as not to do the same things again. If we do not try once more, the lesson we have learned is wasted.Finally, we should never give up because as we work to reach our goals, we develop confidence, and this confidence can help us succeed in other areas of our lives. If we never challenge(挑战) ourselves, we will begin to doubt our abilities.In short, it is important that we do not give up when working for our goals. We succeed in the end or not, we will learn something , and what we learn will help us to become better and more confident. What's more, if we give up , we have no chance of realizing our dreams any more , but if we keep making great efforts, there is always a chance that we will be successful one day.Topic: Never Give Up来源学科网ZXXK]Possible meanings and the author's opinions The words " Never give up" can encourage others or oneself .

She noticed a rare punk rock CD that she also owned. At that moment, she realized that they both had the same interest in music and they started talking. Sue said, “I thought we had nothing in common (相同) until I saw his CD by the New York Dolls.” They are now married and living with each other.Some psychologists (心理学家) think that your taste in music is related to (有联系的) your personality. As part of a test at the University of Texas, Austin, USA, volunteers created a CD of their favourite songs. The volunteers then listened to each other’s CDs and made guesses about the CD crea tor’s personality—outgoing, adventurous, happy, and so on. These strangers correctly guessed (猜) much more about each other’s personalities through their CDs than through their clothes or taste in films. For example, Sue and Jim love punk music, which means they have outgoing personalities.The psychologists who did the test found Snoop Dogg (hip-hop) fans are likely to be energetic and talkative. People who like U2 (rock / pop music) are generally independent and adventurous.The psychologists also found that Louis Armstrong (jazz) fans tend to (倾向于) be serious and intelligent while fans of classical music are also likely to enjoy jazz and tend to be shy. The psychologists were surprised to find that rap and heavy metal fans were also shier and quieter than many other music lovers.Title: Music and PersonalityAn opinion◆Your taste in music is related to your personality.Findings ◆One’s clothes or taste in films is __1__ important than his / her CDs in a test of guessing aboutone’s personality.◆It is likely that hip-hop fans are energetic and talkative.◆People who __2__ rock or pop music are usually independent and adventurous.◆Jazz fans tend to be serious and intelligent.◆It’s __3__ that rap and heavy metal fans are shier and quieter than many other music lovers.

第25课:Earth and Sky科普英语：Acid Rain 酸雨Damage from acid rain is widespread - not just in eastern North America, but throughout Europe, Japan, China, and Southeast Asia. Is the rain that's falling on your umbrella acidic? A listener's question -- on today's Earth and Sky.JB: This is Earth and Sky with a question from Sandra Renee of Olive Hill, Kentucky. She asks, "How do you know when it rains that it's not acid rain, and what exactly is acid rain?"DB: Sandra, you need a pH meter to reliably measure the acidity of rain or snow. But in certain parts of the US -- especially in the Northeast -- you can probably assume that most rain will be at least somewhat acidic. Westerly winds move pollutants eastward, so the eastern US gets more acid rain.JB: Acid rain happens when airborne acids fall down to Earth in rain. Electrical utility plants that burn fossil fuels emit chemicals into the atmosphere that react with water and other chemicals in the air to form sulfuric acid, nitric acid -- the "acid" in acid rain. You don't have to live next door to a plant to get showered by acid rain. These acid pollutants reach high into the atmosphere and can travel with wind currents for hundreds of kilometers.DB: The acids in acid rain are corrosive chemicals that leach nutrients from the soils, slow the growth of trees, poison lakes and combine with other chemicals to form urban smog. The simplest way to curtail acid rain is to use less energy from fossil fuels.JB: Special thanks today to the Camille & Henry Dreyfus Foundation, a private foundation dedicated to advancing research and education in the chemical sciences. We're Block and Byrd for Earth and Sky.。

Mung beans in different pHAimIn this experiment, I am investigating the relationship between acid rain and mung beans. To accomplish this goal, I am going to test themung beansindifferentpHsuchaspH1,3,5,7 and measure the growth.This experiment is important because I want to see if acid rain will really affect the growth of mung beans. What I am measuring is the growth of mung beans, which is the length of bean sprouts; and what I am changing is the PH level of water. From my research, I found that acid rain will harm the plants, pollute the water and cause the erosion of rock (Rinkesh, 2009).HypothesisIf there is a relationship between mung bean’s growth and pH level, then I predict that the mung beansgrownin pH5 will be better than pH1,3,7. I predict this because, from my research, there are some poison chemicals inside the acid rain, it may harm the plant a lot. Also, if the pH level is lower than 3, some necrotic spots will form on the surfaceof leaves, the stoma will be broken; that will affect the ability to done photosynthesis, then acid rain will despoil calcium and magnesium. The plant will become weak slowly until they are dead.So, in this case, theacidic liquid can be the acid rain, mung beans can be the plant that affects by acid rain(Casiday and Frey, 1998).VariableIndependent: pH1,3,5,7PH value is what I will change before the experiment, I will put four different pH liquids in four boxes. It may cause the growth of mung beans.DependentGrowth of mung beans (Length)The length of mung bean is what I will measure after 7 days. It changes depends on what liquid it grows in. I will measure every single bean and calculate the average. The unit is mm.MaterialsThe data of mung bean’s growth in pH1,3,5,7Procedure1.Prepare all the materials. each cup of the pH liquid (1.3.5.7)3.Open the lid of each cup.4.Put 2 tissues in each cup.5.Place 10 mung beans on the tissue.e the dropper to drop 40mL of each pH on the tissue.7.Put 1 tissue on the top of mung beans.8.Drop 10mL more liquid on each tissue.9.Put the lid on, and wait for 7 days.10.On the 7th day, open the cup and check the growth ofmung beans.Data PresentationData AnalysingFrom my graph, we can see the beans grown in pH3 is better than the others. The average of mung beans’ length is 32.3mm, the longest one. Mung beans that grew in pH5 are in the second place. Beans grew in pH7 is the third one. And pH1 is the last one.Procedure EvaluatingThere are some problems in my experiment procedurethat I have to fix. I think the amount of liquid add to the box should be equal. If that is not the same, the result may not be very accurate. So, I need to make sure that I add the same amount of pH liquid. For example, if I add 30 mL pH1 liquid to the first cup, then I need to add 30 mL to other containers. By the way, the contain we used should have same size. That may affect the growth of mung beans.ConclusionFrom the data, we can see that mung beans grew in pH3 liquid is the best one out of four. Also, mung beans that grew in pH5 is almost same as pH3. By comparison, mung beans grew in pH7, which is in a neutral environment, have a great difference with them. Which means mung beans is suitable to an acidic environment. My prediction was a neutral environment is good for mung beans to grow than an acidic environment. Therefore, my prediction is not supported.ReferencesRinkesh (2009).

关于酸雨的报告英语作文English Answer：Acid Rain: An Impending Environmental Crisis.Acid rain, a vexing environmental issue, results from the emission of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, primarily by power plants and industrial activities. These compounds react with water, oxygen, and other chemicals in the atmosphere to form sulfuric acid (H2SO4) and nitric acid (HNO3), which subsequently condense into precipitation as acid rain.Acid rain poses significant threats to ecosystems and human health. In aquatic ecosystems, it acidifies lakes and streams, leading to the death of fish and other aquatic life. Terrestrial ecosystems are also affected, as it damages forests and crops, making them more susceptible to pests and diseases. Acid rain can also contribute to the deterioration of buildings and infrastructure, particularlythose made of limestone or marble.Moreover, acid rain has adverse effects on human health. It can cause respiratory problems, such as asthma and bronchitis, especially in children and the elderly. Extended exposure to acid rain can also lead to cardiovascular issues.Numerous strategies have been implemented to mitigate acid rain, including the introduction of stricterregulations on industrial emissions, the promotion of renewable energy sources, and the development of technologies that reduce SO2 and NOx emissions. However, much more needs to be done to combat this pressing environmental challenge.Addressing Acid Rain: A Path Forward.Tackling the issue of acid rain requires a concerted effort on both local and global levels. The implementationof stricter regulations on industrial emissions isessential to reduce the release of SO2 and NOx into theatmosphere. Governments can also incentivize the use of renewable energy sources, such as solar and wind power, to replace fossil fuels.Investing in research and development is crucial to advance technologies that minimize SO2 and NOx emissions. The development of more efficient combustion processes, the use of scrubbers, and the adoption of carbon capture and storage systems can significantly reduce the release of these pollutants.International cooperation is also vital in combating acid rain. Transboundary air pollution contributes to acidification in many regions, necessitating collaboration among nations to reduce emissions. Global agreements, such as the 1999 Gothenburg Protocol, provide a framework for countries to work together to address the issue.Public awareness and education play a significant role in mitigating acid rain. By raising awareness about the impacts of acid rain, individuals can make informed choices that contribute to reducing emissions. Educational programscan foster an understanding of the issue and encourage citizens to support policies and measures that promoteclean air.By implementing these comprehensive strategies, we can make significant strides in reducing acid rain and safeguarding the health of our ecosystems and ourselves.Chinese Answer：酸雨，迫在眉睫的环境危机。
