安慰考试压力大的李华英语作文1I know you are feeling down because of the great pressure from exams. Believe me, I have been through the same situation before. There were times when I felt so stressed that I thought I couldn't handle it anymore. But I found some effective ways to cope with it.I started to do some sports like jogging and playing basketball. The physical activity helped me to release the tension and made me feel more energetic. Also, listening to music was a wonderful way for me to relax. The beautiful melodies could soothe my mind and take me to a peaceful world.I also want to tell you about one of my classmates. He was under huge pressure before an important exam, but he managed to overcome it. He made a detailed study plan and stuck to it strictly. He took breaks regularly and did things he enjoyed to relieve stress. Eventually, he performed very well in the exam.Li Hua, remember that exams are not the only thing in life. They are just a way to test our knowledge and skills. Don't let the pressure overwhelm you. Keep a positive attitude and believe in yourself. I'm sure you will do well.Best wishes![Your Name]2Exams can be a source of great stress for many students, and Li Hua is no exception. The reasons behind this stress are numerous. One common cause is having overly high expectations. When one sets an extremely high goal for themselves, the fear of not achieving it can weigh heavily and create immense pressure. For instance, aiming for a perfect score in every exam can be overwhelming.Another reason could be insufficient preparation. If one has not dedicated enough time to study and review the materials, the uncertainty and anxiety about the exam can be quite intense.However, there are effective ways to deal with this stress. Firstly, it's crucial to adjust one's mindset. One should understand that not every exam result needs to be perfect, and progress is more important than absolute success. By accepting this, the pressure can be significantly reduced. Secondly, proper planning of study time is essential. Making a detailed study schedule and sticking to it can ensure that one is well-prepared and thus more confident. For example, allocating specific time slots for each subject and regularly reviewing what has been learned can make a big difference.In conclusion, exam stress is manageable as long as we understand its causes and take appropriate measures. Li Hua, I believe you can overcomethis challenge and perform well in your exams.3One day, Li Hua was under great pressure because of the upcoming exams. To comfort him, we decided to organize a class gathering.When we all gathered in the park, everyone surrounded Li Hua. We shared our own experiences of dealing with exam stress and told him that it was just a temporary challenge. "Li Hua, you are not alone. We are all here for you," said one classmate. Another added, "We believe in your ability. You have always been excellent and this time will be no exception."I also recalled the time when our teacher patiently guided another stressed classmate. The teacher's gentle words and encouraging smile made that classmate regain confidence. We told Li Hua that he could do the same.At that moment, Li Hua's eyes shone with gratitude and determination. He knew that no matter how difficult the exams were, he had our support and encouragement. This gathering not only comforted Li Hua but also strengthened the bond among us. We all understood that in the face of challenges, unity and support were the most powerful weapons.4Last month, my friend Li Hua was under huge pressure due to the approaching exams. I decided to stand by his side and help him get through this tough time.We started by making a detailed study plan together. We divided the subjects and allocated specific time for each one. Every day, we would check on each other's progress and offer support and encouragement. When Li Hua felt frustrated or confused, I would patiently explain the difficult points to him.Sometimes, when Li Hua was too exhausted from studying, I would suggest going for a walk. We would chat about various things, not related to exams but about our hobbies, dreams, and funny stories. During these walks, he could relax his mind and regain his energy.With our joint efforts, Li Hua gradually became more confident and less stressed. He was able to face the exams with a positive attitude. I felt really happy for him because I knew that our friendship and my support had made a difference.5Exams can bring a lot of stress to students like Li Hua. But let's look at this stress from different perspectives. Stress can actually have positive meanings. It can stimulate our potential. For example, when we face the pressure of an important exam, we might discover abilities within ourselves that we never knew existed. This pressure drives us to study harder and aim for better results.However, dealing with exam stress requires strategies. Maintaining a good schedule is crucial. We should ensure enough sleep and proper rest tokeep our minds sharp. Regular exercise can also help us relieve stress and stay energetic. Besides, a balanced diet provides the necessary nutrients for our brains to function well.In conclusion, exam stress is not all bad. It can be a motivation for us to improve. With the right approaches, we can turn this stress into a driving force for success. So, Li Hua, don't be too worried. Believe in your abilities and keep moving forward.。
汽轮机油酸值的测定The determination of acidity in turbine oil is acrucial aspect of maintaining the efficiency and longevityof turbine machinery. The acidity level of turbine oil isan indicator of its degradation and can provide valuable insights into the condition of the machine. In this discussion, we will explore the importance of measuring turbine oil acidity, the methods used for its determination, the significance of accurate measurements, and the implications of high acidity levels on turbine performance.Firstly, it is essential to understand why measuringthe acidity of turbine oil is necessary. Turbine oil is subjected to high temperatures and oxidative stress during its operation, which can lead to the formation of acidic compounds. These compounds can cause corrosion, reduce lubrication effectiveness, and accelerate the degradationof the oil. By regularly monitoring the acidity level, maintenance personnel can assess the condition of the oil and take appropriate actions to prevent potential damage tothe turbine.Several methods are available for the determination of turbine oil acidity. One widely used technique is the Total Acid Number (TAN) test. TAN is a measure of the quantity of acidic compounds present in the oil and is determined by titration with a standardized alkaline solution. Another method is the Neutralization Number (NN) test, which measures the amount of alkaline additive required to neutralize the acid present in the oil. Both methodsprovide valuable information about the oil's acidity level and can assist in determining the need for oil replacementor reconditioning.Accurate measurements of turbine oil acidity are vital for making informed decisions regarding maintenance and oil replacement. Regular monitoring allows for the early detection of abnormal acidity levels, which can indicate potential issues such as increased oxidation, contamination, or inadequate lubrication. By addressing these problems promptly, maintenance personnel can prevent costly repairs, unplanned downtime, and even catastrophic failures.Furthermore, accurate measurements help in evaluating the effectiveness of preventive maintenance measures and the performance of the oil purification system.High acidity levels in turbine oil can have severe implications on turbine performance. Acidic compounds can corrode metal surfaces, leading to the formation of deposits and wear particles. This corrosion can degrade the efficiency of the turbine, reduce power output, and increase fuel consumption. Additionally, acidic oil can cause damage to seals, bearings, and other critical components, resulting in increased maintenance costs and decreased reliability. Therefore, it is crucial to maintain the acidity of turbine oil within acceptable limits to ensure optimal turbine performance and longevity.In conclusion, the determination of acidity in turbine oil is an essential aspect of turbine maintenance. Accurate measurements using techniques such as TAN or NN tests provide valuable insights into the condition of the oil and the turbine machinery. Regular monitoring of acidity levels allows for proactive maintenance, preventing potentialdamage and ensuring optimal turbine performance. By understanding the importance of measuring turbine oil acidity, maintenance personnel can take the necessary steps to maintain the integrity and efficiency of turbine systems.。

A preliminary test is made in which a specimen section of the roof is subjected to the effects of flame in the absence of radiation.Unless the specimen is so affected by this test that it is obvious it would not pass the principal tests, i.e. the penetration and the spread of flame tests, these are then carried out using the radiated heat apparatus.BS 476-3:2004 describes the three stage test method incorporating burning brands, wind and supplementary radiant heat.BS 476-4:建筑材料和结构的防火测试-材料不燃性测试BS 476-4:Fire tests on building materials and structures - Part 4: Non-combustibility test for materialsAbstract 摘要This British Standard, a part of the BS 476 series, specifies a method of test for determining whether building materials are non-combustible within the meaning of the definition.Materials used in the construction and finishing of buildings or structures are classified “non-combustible” or “combustible” according to their behaviour in the “non-combustibility t est”.This test is intended for building materials, whether coated or not, but it is not intended to apply to the coating alone.BS 476-5:建筑材料引燃性测试方法BS 476-5:Fire Tests on Building Materials and Structures Part 5: Method of Test for IgnitabilityAbstract 摘要This part of this British Standard specifies a method of test for the determination of the ignitability characteristics of the exposed surfaces of essentially flat, rigid or semi-rigid building materials or composites, when tested in the vertical position.BS 476-6:建筑材料和构件的防火测试.第6部分:制品火势蔓延的测试方法BS 476-6:Fire tests on building materials and structures — Part 6: Method of test for fire propagation for productsAbstract 摘要Construction materials, Fire tests, Fire propagation, Testing conditions, Ceiling linings, Ceilings, Wall linings, Walls, Construction systems parts, Test specimens, Specimen preparation, Test equipment, Calibration, Mathematical calculations, Comparative tests, Fire-test classifications, Structural fire protection, Fire safety in buildingsBS 476-7:建筑材料和构件的防火测试.第7部分:测定产品火焰表面蔓延分类的测试方法BS 476-7:Fire Tests on Building Materials and Structures Part 7: Method of Test to Determine the Classification of the Surface Spread of Flame of ProductsAbstract 摘要This British Standard, a part of the BS 476 series, specifies a method of test for measuring the lateral spread of flame along the surface of a specimen of a product orientated in the vertical position under opposed flow conditions, and a classification system based on the rate and extent of the spread of flame.This standard provides data suitable for comparing the end-use performances of essentially flat materials, composites or assemblies, which are used primarily as the exposed surfaces of walls or ceilings.Guidance to operators carrying out this method of test, the effect of thermal characteristics on the performance of assemblies, advice on the construction and preparation of test specimens, and information on the validation of this method are provided in annexes to this standard.BS 476-11:建筑材料和构件的防火测试.第11部分:建筑材料热辐射的判定方法BS 476-11:Fire tests on building materials and structures — Part 11: Method for assessing the heat emission from building materialsAbstract 摘要Fire tests, Construction materials, Heat measurement, Test equipment, Reports, Heat transferBS 476-12:建筑材料和构件的防火测试.第12部分:与火焰直接接触制品可燃性测试方法BS 476-12:Fire tests on building materials and structures — Part 12: Method of test for ignitability of products by direct flame impingementAbstract 摘要Construction materials, Construction systems parts, Fire tests, Ignitability, Flames, Specimen preparation, Vertical, Safety measures, Test equipment, Testing conditions, Test atmospheres, Test specimens, Fire safety in buildings以上资料由防火资源网()防火测试中心整理或发布。
过火验金的流程和注意事项英文回答:Fire assay, also known as cupellation, is a common method used for the determination of precious metals, such as gold and silver, in ores and other materials. The process involves the separation of the precious metals from impurities through the use of high temperatures and chemical reactions. Here is a step-by-step guide on thefire assay process and some important considerations:1. Sample Preparation: The first step is to obtain a representative sample of the material to be assayed. This can be done by taking multiple samples from different parts of the material and then combining them to create a homogeneous mixture. The sample is then crushed and ground to a fine powder.2. Fusion: The powdered sample is mixed with fluxing agents, such as litharge (lead oxide) and borax, tofacilitate the fusion of the sample. The mixture is then heated in a crucible at high temperatures, typically around 1,100 to 1,200 degrees Celsius, until it melts and forms a molten button.3. Cupellation: The molten button is placed in a cupel, which is a small, shallow dish made of bone ash or magnesia. The cupel is then placed in a furnace and heated at high temperatures. During this process, the lead in the button oxidizes and is absorbed by the cupel, leaving behind abead of precious metals.4. Parting: The bead of precious metals is then treated with nitric acid to dissolve the silver, leaving behindonly the gold. The gold can then be weighed and its purity determined.5. Calculation of Results: The weight of the gold is used to calculate the amount of gold in the original sample. This is done by taking into account the weight of the sample and the weight of the bead of gold.Some important considerations for fire assay include:1. Safety: Fire assay involves working with high temperatures and chemicals, so it is important to take proper safety precautions. This includes wearing protective clothing, such as gloves and goggles, and working in awell-ventilated area.2. Accuracy: Fire assay is a precise method for the determination of precious metals, but it is important to ensure that the sample is representative and that all steps of the process are carried out correctly to obtain accurate results.3. Contamination: Contamination can affect the accuracy of the assay results. It is important to clean all equipment thoroughly before and after each assay to avoid cross-contamination.4. Quality Control: To ensure the reliability of the assay results, it is important to implement quality control measures, such as using certified reference materials andperforming regular checks and calibrations of equipment.中文回答:过火验金,也被称为杯测法,是一种常用于测定矿石和其他材料中的贵金属(如金和银)的方法。

THE PRESIDENT: Thank you very much. (Applause.) Thank you. (Applause.) Please be seated.An earthquake and a hurricane may have delayed this day, but this is a day that would not be denied.For this day, we celebrate Dr. Martin Luther King, Jr.’s return to the National Mall. In this place, he will stand for all time, among monuments to those who fathered this nation and those who defended it; a black preacher with no official rank or title who somehow gave voice to our deepest dreams and our most lasting ideals, a man who stirred our conscience and thereby helped make our union more perfect.And Dr. King would be the first to remind us that this memorial is not for him alone. The movement of which he was a part depended on an entire generation of leaders. Many are here today, and for their service and their sacrifice, we owe them our everlasting gratitude. This is a monument to your collective achievement. (Applause.)Some giants of the civil rights movement ?- like Rosa Parks and Dorothy Height, Benjamin Hooks, Reverend Fred Shuttlesworth ?- they’ve been taken from us these past few years. This monument attests to their strength and their courage, and while we miss them dearly, we know they rest in a better place.And finally, there are the multitudes of men and women whose names never appear in the history books ?- those who marched and those who sang, those who sat in and those who stood firm, those who organized and those who mobilized ?- all those men and women who through countless acts of quiet heroism helped bring about changes few thought were even possible. “By the thousands,” said Dr. King, “faceless, anonymous, relentless young people, black and white…have take n our whole nation back to those great wells of democracy which were dug deep by the founding fathers in the formulation of the Constitution and the Declaration of Independence.”To those men and women, to those foot soldiers for justice, know that this monument is yours, as well.Nearly half a century has passed since that historic March on Washington, a day when thousands upon thousands gathered for jobs and for freedom. That is what our schoolchildren remember best when they think of Dr. King -? his booming voice across this Mall, calling on America to make freedom a reality for all of God’s children, prophesizing of a day when the jangling discord of our nation would be transformed into a beautiful symphony of brotherhood.It is right that we honor tha t march, that we lift up Dr. King’s “I Have a Dream” speech ?- for without that shining moment, without Dr. King’s glorious words, we might not have had the courage to come as far as we have. Because of that hopeful vision, because of Dr. King’s moral imagination, barricades began to fall and bigotry began to fade. New doors of opportunity swung open for an entire generation. Yes, laws changed, but hearts and minds changed, as well.Look at the faces here around you, and you see an America that is more fair and more free and more just than the one Dr. King addressed that day. We are right to savor that slow but certain progress -? progress that’s expressed itself in a million ways, large and small, across this nation every single day, as people of all colors and creeds live together, and work together, and fight alongside one another, and learn together, and build together, and love one another.So it is right for us to celebrate today Dr. King’s dream and his vision of unity. And yet it is also important on this day to remind ourselves that such progress did not come easily; that Dr. King’s faith was hard-won; that it sprung out of a harsh reality and some bitter disappointments.It is right for us to celebrate Dr. King’s marvelous oratory, but it is worth remembering that progress did not come from words alone. Progress was hard. Progress was purchased through enduring the smack of billy clubs and the blast of fire hoses. It was bought with days in jail cells and nights of bomb threats. For every victory during the height of the civil rights movement, there were setbacks and there were defeats.We forget now, but during his life, Dr. King wasn’t always considered a unifying figure. Even after rising to prominence, even after winning the Nobel Peace Prize, Dr. King was vilified by many, denounced as a rabble rouser and an agitator, a communist and a radical. He was even attacked by his own people, by those who felt he was going too fast or those whofelt he was going too slow; by those who felt he shouldn’t meddle in issues like the Vietnam War or the rights of union workers. We know from his own testimony the doubts and the pain this caused him, and that the controversy that would swirl around his actions would last until the fateful day he died.I raise all this because nearly 50 years after the March on Washington, our work, Dr. King’s work, is not yet complete. We gather here at a moment of great challenge and great change. In the first decade of this new century, we have been tested by war and by tragedy; by an economic crisis and its aftermath that has left millions out of work, and poverty on the rise, and millions more just struggling to get by. Indeed, even before this crisis struck, we had endured a decade of rising inequality and stagnant wages. In too many troubled neighborhoods across the country, the conditions of our poorest citizens appear little changed from what existed 50 years ago -? neighborhoods with underfunded schools and broken-down slums, inadequate health care, constant violence, neighborhoods in which too many young people grow up with little hope and few prospects for the future.Our work is not done. And so on this day, in which we celebrate a man and a movement that did so much for this country, let us draw strength from those earlier struggles. First and foremost, let us remember that change has never been quick. Change has never been simple, or without controversy. Change depends on persistence. Change requires determination. It took a full decade before the moral guidance of Brown v. Board of Education was translated into the enforcement measures of the Civil Rights Act and the Voting Rights Act, but those 10 long years did not lead Dr. King to give up. He kept on pushing, he kept on speaking, he kept on marching until change finally came. (Applause.)And then when, even after the Civil Rights Act and the Voting Rights Act passed, African Americans still found themselves trapped in pockets of poverty across the country, Dr. King didn’t say those laws were a failure; he didn’t say this is too hard; he didn’t say, let’s settle for what we got and go home. Instead he said, let’s take those victories and broaden our mission to achieve not just civil and political equality but also economic justice; let’s fight for a living wage and better schools and jobs for all who are willing to work. In other words, when met with hardship, when confronting disappointment, Dr. King refused to accept what he called the “isness” of today. He kept pushing towards the “oughtness” of tomorrow.And so, as we think about all the work that we must do ?- rebuilding aneconomy that can compete on a global stage, and fixing our schools so that every child -- not just some, but every child -- gets a world-class education, and making sure that our health care system is affordable and accessible to all, and that our economic system is one in which everybody gets a fair shake and everybody does their fair share, let us not be trapped by what is. (Applause.) We can’t be discouraged by what is. We’ve got to keep pushing for what ought to be, the America we ought to leave to our children, mindful that the hardships we face are nothing compared to those Dr. King and his fellow marchers faced 50 years ago, and that if we maintain our faith, in ourselves and in the possibilities of this nation, there is no challenge we cannot surmount.And just as we draw strength from Dr. King’s struggles, so must we draw inspiration from his constant insistence on the oneness of man; the belief in his words that “we are caught in an inescapable network of mutuality, tied in a single garment of destiny.” It was that insistence, rooted in his Christian faith, that led him to tell a group of angry young protesters, “I love you as I love my own children,” even as one threw a rock that glanced off his neck.It was that insistence, that belief that God resides in each of us, from the high to the low, in the oppressor and the oppressed, that convinced him that people and systems could change. It fortified his belief in non-violence. It permitted him to place his faith in a government that had fallen short of its ideals. It led him to see his charge not only as freeing black America from the shackles of discrimination, but also freeing many Americans from their own prejudices, and freeing Americans of every color from the depredations of poverty.And so at this moment, when our politics appear so sharply polarized, and faith in our institutions so greatly diminished, we need more than ever to take heed of Dr. King’s teachings. He calls on us to stand in the other person’s shoes; to see through their eyes; to understand their pain. He tells us that we have a duty to fight against poverty, even if we are well off; to care about the child in the decrepit school even if our own children are doing fine; to show compassion toward the immigrant family, with the knowledge that most of us are only a few generations removed from similar hardships. (Applause.)To say that we are bound together as one people, and must constantly strive to see ourselves in one another, is not to argue for a false unity that papers over our differences and ratifies an unjust status quo. As was true 50 years ago, as has been true throughout human history, those with power and privilege will often decry any call for change as “divisive.”They’ll say any challenge to the existing arrangements are unwise and destabilizing. Dr. King understood that peace without justice was no peace at all; that aligning our reality with our ideals often requires the speaking of uncomfortable truths and the creative tension of non-violent protest.But he also understood that to bring about true and lasting change, there must be the possibility of reconciliation; that any social movement has to channel this tension through the spirit of love and mutuality.If he were alive today, I believe he would remind us that the unemployed worker can rightly challenge the excesses of Wall Street without demonizing all who work there; that the businessman can enter tough negotiations with his company’s union w ithout vilifying the right to collectively bargain. He would want us to know we can argue fiercely about the proper size and role of government without questioning each other’s love for this country -- (applause) -- with the knowledge that in this democracy, government is no distant object but is rather an expression of our common commitments to one another. He would call on us to assume the best in each other rather than the worst, and challenge one another in ways that ultimately heal rather than wound.In the end, that’s what I hope my daughters take away from this monument.I want them to come away from here with a faith in what they can accomplish when they are determined and working for a righteous cause. I want them to come away from here with a faith in other people and a faith in a benevolent God. This sculpture, massive and iconic as it is, will remind them of Dr. King’s strength, but to see him only as larger than life would do a disservice to what he taught us about ourselves. He would want them to know that he had setbacks, because they will have setbacks. He would want them to know that he had doubts, because they will have doubts. He would want them to know that he was flawed, because all of us have flaws.It is precisely because Dr. King was a man of flesh and blood and not a figure of stone that he inspires us so. His life, his story, tells us that change can come if you don’t give up. He would not give up, no matter how long it took, because in the smallest hamlets and the darkest slums, he had witnessed the highest reaches of the human spirit; because in those moments when the struggle seemed most hopeless, he had seen men and women and children conquer their fear; because he had seen hills and mountains made low and rough places made plain, and the crooked places made straight and God make a way out of no way.And that is why we honor this man ?- because he had faith in us. And thatis why he belongs on this Mall -? because he saw what we might become. That is why Dr. King was so quintessentially American -- because for all the hardships we’ve endured, for all our sometimes tragic history, ours is a story of optimism and achievement and constant striving that is unique upon this Earth. And that is why the rest of the world still looks to us to lead. This is a country where ordinary people find in their hearts the courage to do extraordinary things; the courage to stand up in the face of the fiercest resistance and despair and say this is wrong, and this is right; we will not settle for what the cynics tell us we have to accept and we will reach again and again, no matter the odds, for what we know is possible.That is the conviction we must carry now in our hearts. (Applause.) As tough as times may be, I know we will overcome. I know there are better days ahead. I know this because of the man towering over us. I know this because all he and his generation endured -- we are here today in a country that dedicated a monument to that legacy.And so with our eyes on the horizon and our faith squarely placed in one another, let us keep striving; let us keep struggling; let us keep climbing toward that promised land of a nation and a world that is more fair, and more just, and more equal for every single child of God.Thank you, God bless you, and God bless the United States of America. (Applause.)。
apec蓝英语作文In the heart of Beijing, amidst the bustling city life andthe historical grandeur of its ancient monuments, a phenomenon known as the "APEC Blue" emerged during the Asia-Pacific Economic Cooperation (APEC) summit in 2014. This unique term has since become synonymous with the hope for a cleaner and more sustainable environment. The APEC Bluerefers to the unusually clear and blue sky that was observed during the event, a stark contrast to the city's notorious smog.The appearance of the APEC Blue was not a mere coincidencebut a result of stringent measures taken by the Chinese government to ensure a clean environment for theinternational delegates. Factories were temporarily shut down, construction activities halted, and traffic restrictions were imposed, reducing the levels of air pollution significantly. The skies, once obscured by a thick layer of smog, revealed a vibrant blue that captivated the hearts of the citizens andthe world.The APEC Blue serves as a powerful symbol of what can be achieved when collective efforts are made towards environmental conservation. It is a reminder that the fight against pollution is not insurmountable, and that with determination and the right policies, we can reclaim our blue skies.However, the challenge lies in maintaining this clarity inthe sky beyond the duration of high-profile events. The temporary nature of the measures taken for the APEC summit highlights the need for long-term solutions and sustainable practices. It is imperative that the lessons learned from the APEC Blue are not forgotten, but rather serve as a catalystfor permanent changes in our approach to environmental protection.The quest for the APEC Blue is not just a Chinese endeavorbut a global one. As cities around the world grapple with the effects of pollution, the strategies employed during the APEC summit can provide valuable insights. International cooperation, technological innovation, and a shift towards greener energy sources are essential components in this fight.In conclusion, the APEC Blue is more than just a beautiful sight; it is a beacon of hope for a future where clean airand blue skies are not the exception but the norm. It is a testament to the fact that with collective will and action,we can overcome the challenges of environmental degradation. Let the APEC Blue inspire us to strive for a cleaner, greener, and healthier planet for generations to come.。

中华人民共和国企业所得税法英文The Enterprise Income Tax Law of the People's Republic of China (EIT Law) is a vital legislation that governs the taxation of profits earned by enterprises in China. Implemented in 2008, it aims to promote fairness, encourage economic growth, and ensure the sustainable development of the country.The EIT Law establishes a set of rules and regulationsfor the determination, calculation, and payment of enterprise income taxes. It covers various aspects related to the taxation of both domestic and foreign enterprises operating within China's jurisdiction. The law requires enterprises to accurately report their financial information, including revenue, costs, and expenses, while adhering to theprinciples of legality, authenticity, and integrity.One of the key features of the EIT Law is the progressive tax rate system, wherein enterprises are subject to different tax rates based on their taxable income. This ensures that smaller businesses with lower profits are taxed at a more affordable rate, while larger enterprises make a greater contribution to the nation's tax revenue. It also encouragesenterprises to reinvest their profits, as certain eligible investments can qualify for preferential tax treatments or exemptions.To further enhance tax administration, the EIT Law introduced anti-tax avoidance measures, aimed at preventing enterprises from exploiting loopholes to evade taxes. Transfer pricing regulations, thin capitalization rules, and controlled foreign company provisions are among the mechanisms implemented to counteract aggressive tax planning practices. These measures not only protect the interests of the Chinese economy but also foster a fair and competitive business environment.While the EIT Law imposes obligations on taxpayers, it also provides incentives to stimulate technological innovation, environmental protection, and regional development. Enterprises engaged in qualified research and development activities, environmental protection projects, or investments in underdeveloped areas may benefit from reduced tax rates or other forms of support. These incentives encourage businesses to contribute to China's economic transformation and ecological advancement.Moreover, the EIT Law demonstrates China's commitment to international tax cooperation. As a member of the globalcommunity, China actively participates in the implementation of the Base Erosion and Profit Shifting (BEPS) project initiated by the Organization for Economic Cooperation and Development (OECD). By aligning its tax policies with international standards, China strives to promote transparency, combat tax evasion, and create a level playing field for enterprises worldwide.The enforcement of the EIT Law relies on effective tax administration and rigorous compliance. Tax authorities conduct regular audits and inspections to ensure the accuracy of taxpayers' financial records and the adherence to tax regulations. Enterprises are encouraged to maintain a good relationship with tax authorities, fulfill their tax obligations timely, as well as seek professional advice when necessary.In conclusion, the Enterprise Income Tax Law of the People's Republic of China plays a fundamental role in the taxation of profits earned by enterprises, contributing to the nation's economic growth and development. With its comprehensive provisions, including progressive tax rates, anti-tax avoidance measures, and incentives for innovation, the law establishes a fair, transparent, and conduciveenvironment for enterprises, both domestic and foreign, to thrive and contribute to China's prosperity.。
英语演讲稿16日美国总统奥巴马在马丁路德·金纪念堂正式落成时发表的罕见激情洋溢演讲President Obama at the Martin Luther King, Jr. Memorial Dedication:We Will OvercomeTHE PRESIDENT: Thank you very much. (Applause.) Thank you. (Applause.) Please be seated.An earthquake and a hurricane may have delayed this day, but this is a day that would not be denied.For this day, we celebrate Dr. Martin Luther King, Jr.’s return to the National Mall. In this place, he will stand for all time, among monuments to those who fathered this nation and those who defended it; a black preacher with no official rank or title who somehow gave voice to our deepest dreams and our most lasting ideals, a man who stirred our conscience and thereby helped make our union more perfect.And Dr. King would be the first to remind us that this memorial is not for him alone. The movement of which he wasa part depended on an entire generation of leaders. Many are here today, and for their service and their sacrifice, we owe them our everlasting gratitude. This is a monument to your collective achievement. (Applause.)Some giants of the civil rights movement ?- like Rosa Parks and Dorothy Height, Benjamin Hooks, Reverend Fred Shuttlesworth ?- they’ve been taken from us these past few years. This monument attests to their strength and their courage, and while we miss them dearly, we know they rest in a better place.And finally, there are the multitudes of men and women whose names never appear in the history books ?- those who marched and those who sang, those who sat in and those who stood firm, those who organized and those who mobilized ?- all those men and women who through countless acts of quiet heroism helped bring about changes few thought were even possible. “By the thousands,”said Dr. King, “faceless, anonymous, relentless young people, black and white…have taken our whole nation back to those great wells of democracy which were dug deep by the founding fathers in the formulation of the Constitution and the Declaration of Independence.” To those men and women, to those foot soldiers for justice, know thatthis monument is yours, as well.Nearly half a century has passed since that historic March on Washington, a day when thousands upon thousands gathered for jobs and for freedom. That is what our schoolchildren remember best when they think of Dr. King -? his booming voice across this Mall, calling on America to make freedom a reality for all of God’s children, prophesizing of a day when the jangling discord of our nation would be transformed into a beautiful symphony of brotherhood.It is right that we honor that march, that we lift up Dr. King’s “I Have a Dream” speech ?- for without that shining moment, without Dr. King’s glorious words, we might not have had the courage to come as far as we have. Because of that hopeful vision, because of Dr. King’s moral imagination, barricades began to fall and bigotry began to fade. New doors of opportunity swung open for an entire generation. Yes, laws changed, but hearts and minds changed, as well.Look at the faces here around you, and you see an America that is more fair and more free and more just than the one Dr. King addressed that day. We are right to savor that slow but certain progress -? progress that’s expressed itself in a million ways, large and small, across this nation every singleday, as people of all colors and creeds live together, and work together, and fight alongside one another, and learn together, and build together, and love one another.So it is right for us to celebrate today Dr. King’s dream and his vision of unity. And yet it is also important on this day to remind ourselves that such progress did not come easily; that Dr. King’s faith was hard-won; that it sprung out of a harsh reality and some bitter disappointments.It is right for us to celebrate Dr. King’s marvelous oratory, but it is worth remembering that progress did not come from words alone. Progress was hard. Progress was purchased through enduring the smack of billy clubs and the blast of fire hoses. It was bought with days in jail cells and nights of bomb threats. For every victory during the height of the civil rights movement, there were setbacks and there were defeats.We forget now, but during his life, Dr. King wasn’t always considered a unifying figure. Even after rising to prominence, even after winning the Nobel Peace Prize, Dr. King was vilified by many, denounced as a rabble rouser and an agitator, a communist and a radical. He was even attacked by his own people, by those who felt he was going too fast or those who felt he was going too slow; by those who felt he shouldn’t meddle in issues like the Vietnam War or the rights of union workers. We know from his own testimony the doubts and the pain this caused him, and that the controversy that would swirl around his actions would last until the fateful day he died.I raise all this because nearly 50 years after the March on Washington, our work, Dr. King’s work, is not yet complete. We gather here at a moment of great challenge and great change. In the first decade of this new century, we have been tested by war and by tragedy; by an economic crisis and its aftermath that has left millions out of work, and poverty on the rise, and millions more just struggling to get by. Indeed, even before this crisis struck, we had endured a decade of rising inequality and stagnant wages. In too many troubled neighborhoods across the country, the conditions of our poorest citizens appear little changed from what existed 50 years ago -? neighborhoods with underfunded schools and broken-down slums, inadequate health care, constant violence, neighborhoods in which too many young people grow up with little hope and few prospects for the future.Our work is not done. And so on this day, in which we celebrate a man and a movement that did so much for this country, let us draw strength from those earlier struggles. First andforemost, let us remember that change has never been quick. Change has never been simple, or without controversy. Change depends on persistence. Change requires determination. It took a full decade before the moral guidance of Brown v. Board of Education was translated into the enforcement measures of the Civil Rights Act and the Voting Rights Act, but those 10 long years did not lead Dr. King to give up. He kept on pushing, he kept on speaking, he kept on marching until change finally came. (Applause.)And then when, even after the Civil Rights Act and the Voting Rights Act passed, African Americans still found themselves trapped in pockets of poverty across the country, Dr. King didn’t say those laws were a failure; he didn’t say this is too hard; he didn’t say, let’s settle for what we got and go home. Instead he said, let’s take those victories and broaden our mission to achieve not just civil and political equality but also economic justice; let’s fight for a living wage and better schools and jobs for all who are willing to work. In other words, when met with hardship, when confronting disappointment, Dr. King refused to accept what he called the “isness” of today. He kept pushing towards the “oughtness”of tomorrow.And so, as we think about all the work that we must do ?- rebuilding an economy that can compete on a global stage, and fixing our schools so that every child -- not just some, but every child -- gets a world-class education, and making sure that our health care system is affordable and accessible to all, and that our economic system is one in which everybody gets a fair shake and everybody does their fair share, let us not be trapped by what is. (Applause.) We can’t be discouraged by what is. We’ve got to keep pushing for what ought to be, the America we ought to leave to our children, mindful that the hardships we face are nothing compared to those Dr. King and his fellow marchers faced 50 years ago, and that if we maintain our faith, in ourselves and in the possibilities of this nation, there is no challenge we cannot surmount.And just as we draw strength from Dr. King’s struggles, so must we draw inspiration from his constant insistence on the oneness of man; the belief in his words that “we are caught in an inescapable network of mutuality, tied in a single garment of destiny.” It was that insistence, rooted in his Christian faith, that led him to tell a group of angry young protesters, “I love you as I love my own children,” even as one threw a rock that glanced off his neck.It was that insistence, that belief that God resides in each of us, from the high to the low, in the oppressor and the oppressed, that convinced him that people and systems could change. It fortified his belief in non-violence. It permitted him to place his faith in a government that had fallen short of its ideals. It led him to see his charge not only as freeing black America from the shackles of discrimination, but also freeing many Americans from their own prejudices, and freeing Americans of every color from the depredations of poverty.And so at this moment, when our politics appear so sharply polarized, and faith in our institutions so greatly diminished, we need more than ever to take heed of Dr. King’s teachings. He calls on us to stand in the other person’s shoes; to see through their eyes; to understand their pain. He tells us that we have a duty to fight against poverty, even if we are well off; to care about the child in the decrepit school even if our own children are doing fine; to show compassion toward the immigrant family, with the knowledge that most of us are only a few generations removed from similar hardships. (Applause.)To say that we are bound together as one people, and must constantly strive to see ourselves in one another, is not toargue for a false unity that papers over our differences and ratifies an unjust status quo. As was true 50 years ago, as has been true throughout human history, those with power and privilege will often decry any call for change as “divisive.”They’ll say any challenge to the existing arrangements are unwise and destabilizing. Dr. King understood that peace without justice was no peace at all; that aligning our reality with our ideals often requires the speaking of uncomfortable truths and the creative tension of non-violent protest.But he also understood that to bring about true and lasting change, there must be the possibility of reconciliation; that any social movement has to channel this tension through the spirit of love and mutuality.If he were alive today, I believe he would remind us that the unemployed worker can rightly challenge the excesses of Wall Street without demonizing all who work there; that the businessman can enter tough negotiations with his company’s union without vilifying the right to collectively bargain. He would want us to know we can argue fiercely about the proper size and role of government without questioning each other’s love for this country -- (applause) -- with the knowledge that in this democracy, government is no distant object butis rather an expression of our common commitments to one another. He would call on us to assume the best in each other rather than the worst, and challenge one another in ways that ultimately heal rather than wound.In the end, that’s what I hope my daughters take away from this monument. I want them to come away from here with a faith in what they can accomplish when they are determined and working for a righteous cause. I want them to come away from here with a faith in other people and a faith in a benevolent God. This sculpture, massive and iconic as it is, will remind them of Dr. King’s strength, but to see him only as larger than life would do a disservice to what he taught us about ourselves. He would want them to know that he had setbacks, because they will have setbacks. He would want them to know that he had doubts, because they will have doubts. He would want them to know that he was flawed, because all of us have flaws.It is precisely because Dr. King was a man of flesh and blood and not a figure of stone that he inspires us so. His life, his story, tells us that change can come if you don’t give up. He would not give up, no matter how long it took, because in the smallest hamlets and the darkest slums, he hadwitnessed the highest reaches of the human spirit; because in those moments when the struggle seemed most hopeless, he had seen men and women and children conquer their fear; because he had seen hills and mountains made low and rough places made plain, and the crooked places made straight and God make a way out of no way.And that is why we honor this man ?- because he had faith in us. And that is why he belongs on this Mall -? because he saw what we might become. That is why Dr. King was so quintessentially American -- because for all the hardships we’ve endured, for all our sometimes tragic history, ours is a story of optimism and achievement and constant striving that is unique upon this Earth. And that is why the rest of the world still looks to us to lead. This is a country where ordinary people find in their hearts the courage to do extraordinary things; the courage to stand up in the face of the fiercest resistance and despair and say this is wrong, and this is right; we will not settle for what the cynics tell us we have to accept and we will reach again and again, no matter the odds, for what we know is possible.That is the conviction we must carry now in our hearts. (Applause.) As tough as times may be, I know we will overcome.I know there are better days ahead. I know this because of the man towering over us. I know this because all he and his generation endured -- we are here today in a country that dedicated a monument to that legacy.And so with our eyes on the horizon and our faith squarely placed in one another, let us keep striving; let us keep struggling; let us keep climbing toward that promised land of a nation and a world that is more fair, and more just, and more equal for every single child of God.Thank you, God bless you, and God bless the United States of America.

介绍珠穆朗玛峰英语作文篇 1Mount Everest, the highest peak in the world, is a truly remarkable and awe-inspiring natural wonder. It is located at the border between China and Nepal. Standing majestically, its peak reaches an astonishing altitude that few can even imagine.The climate of Mount Everest is extremely harsh and unforgiving. The cold is so intense that it chills to the bone, and the air is so thin that breathing becomes a struggle. The lack of oxygen makes every step a challenge for those brave enough to attempt to reach the summit.Despite these difficulties, Mount Everest attracts countless adventurers and mountaineers from all over the world. Its beauty and mystery have captivated the human spirit for generations.The mountain is not just a physical entity but also a symbol of human determination and the power of nature. It stands as a reminder of the vastness and complexity of our planet, and the small yet significant place we occupy in it.篇 2Mount Everest, the highest peak on Earth, stands majestically, captivating the imagination of adventurers and nature enthusiasts alike. Its formation is a result of the powerful forces of plate tectonics over millions of years. The collision and uplift of the Indian and Eurasian plates gave birth to this colossal mountain, shaping the landscape and influencing the surrounding environment.For climbers, ascending Mount Everest is an ultimate challenge. They must brave extreme cold, thin air, and treacherous terrain. The journey is filled with risksand uncertainties. Every step is a battle against nature's might. However, upon reaching the summit, the view is nothing short of breathtaking. A panorama of snow-capped peaks stretching as far as the eye can see, a sea of clouds below, and a sense of accomplishment that words can hardly describe.The presence of Mount Everest has a profound impact on the local ecosystem.

It is home to rare and precious flora and fauna. Among the plants, there are unique alpine species that have adapted to the harsh conditions. Animals like the snow leopard and Himalayan tahr also find their refuge here.However, the ecological environment of Everest faces numerous challenges. Human activities such as climbing expeditions and tourism have brought pollution and disturbances. To protect this precious ecosystem, measures have been taken. Stricter regulations have been imposed on climbing permits, limiting the number of climbers and ensuring they follow environmental guidelines.

The changing climate poses a significant threat, causing melting glaciers and affecting the habitats of the species.The protection of Everest requires continuous efforts and global cooperation. We must recognize its fragility and take responsibility to preserve this natural wonder for future generations. Only through our collective commitment can we ensure the survival and prosperity of the ecosystem of Mount Everest.篇 4Ever since the dawn of human curiosity, Mount Everest has loomed large as a symbol of both challenge and mystery. Early explorers embarked on daring attempts to conquer its heights, driven by an insatiable spirit of adventure. Edmund Hillary and Tenzing Norgay's successful ascent in 1953 marked a significant milestone in the exploration of Everest.The significance of Mount Everest extends far beyond its status as the world's highest peak. In the realm of geography, it serves as a crucial point of reference, influencing weather patterns and climate systems across vast regions. For scientists, it offers a unique laboratory for studying various aspects such as the effects of high altitude on the human body and the dynamics of glacial movements.Moreover, Everest represents the indomitable human spirit, constantly pushing boundaries and defying limitations. It inspires us to reach for the impossible and reminds us of the power of determination and perseverance.In conclusion, Mount Everest stands not only as a physical giant but also as a beacon of human exploration and scientific discovery, leaving an indelible mark on the history of our quest for knowledge and adventure.篇 5Mount Everest, the highest peak on Earth, holds a profound significance in various aspects. In the local culture, it is regarded as a sacred symbol of nature's might and the indomitable spirit of humanity. It stands as a testament to the power and beauty of our planet.The allure of Mount Everest as a tourist destination is undeniable. Its breathtaking scenery, with snow-capped peaks and vast glaciers, leaves visitors in awe. The thrill of conquering such a mighty peak attracts adventurers from all overthe world. Moreover, the journey to the base camp itself offers a unique experience, allowing people to immerse themselves in the raw beauty of the mountains.The development prospects of tourism around Mount Everest are promising. However, it is crucial to ensure sustainable development. Measures should be taken to protect the fragile ecosystem and maintain the balance of nature. This includes controlling the number of visitors and implementing strict environmental protection policies.In conclusion, Mount Everest is not only a geographical wonder but also a cultural icon and a source of inspiration.

英文回答:A strategic plan epasses aprehensive, high-level blueprint that establishes the overarching objectives and goals of an organization, and delineates the potential strategies and tactics that can be employed to attain them. For instance, an enterprise may formulate a strategic plan aimed at augmenting its market share by 15 over the course of the next three years. This plan would delineate the overarching strategies that the organization intends to adopt in order to realize this objective, such as venturing into untapped geographical markets or spearheading the introduction of pioneering products and services.战略计划传递了全面、高层次的蓝图,确定了一个组织的总体目标和目的,并界定了可用来实现这些目标的潜在战略和策略。
企业可以制定一项战略计划,目的是在未来三年内将市场份额增加15个。
该计划将阐述本组织为实现这一目标而打算采取的总体战略,例如进入尚未开发的地域市场或率先推出开创性产品和服务。
So, tactical planning is basically taking the big picture plan and breaking it down into specific actions that different departments or teams can actually do. Let's say apany wants to grab a bigger piece of the market. The tactical plan mightinvolve the marketing teaming up with a targeted ad campaign, the sales crew focusing on building up relationships with key clients, and the product development folks working on adding some cool new features to their products.战术规划基本上是把大局计划分解为不同部门或团队实际上可以做的具体行动。
In the realm of competitive sports,running races are a testament to the spirit of competition and personal achievement.However,these events are not without their risks, as the following narrative illustrates.It was a bright,sunny day,perfect for the annual school sports meet.The air was filled with the scent of freshly mowed grass and the buzz of excitement from the gathered crowd.Among the many events scheduled for the day,the100meter dash was the highlight,drawing the largest audience and the most anticipation.The runners,a diverse group of students from various grades,gathered at the starting line. Their faces were a mix of determination and nervousness,each hoping to claim victory in this sprint of speed and endurance.The atmosphere was electric as the starters pistol was raised,signaling the imminent start of the race.As the shot rang out,the runners burst forward,their legs pumping like pistons as they charged down the track.The initial phase of the race was a blur of motion,with the athletes jostling for position.It was during this chaotic start that the unfortunate incident occurred.One of the runners,a tall,lanky boy with a reputation for speed,was trying to overtake another competitor.In his eagerness,he misjudged the distance and collided with the runner in front of him.The impact was sudden and forceful,causing both boys to stumble and fall to the ground.The crowd gasped as the fallen runners struggled to regain their footing amidst the chaos. The race continued around them,with the remaining competitors pushing forward,their initial advantage now even more significant.The fallen runners,however,were not so lucky.Bruised and shaken,they were helped off the track by concerned officials and medical staff.The incident cast a somber tone over the rest of the event.While the race was ultimately won by a swift and agile girl,the victory was somewhat overshadowed by the earlier collision.It served as a stark reminder of the inherent risks involved in such highspeed sports and the importance of safety and caution in all competitive endeavors.In the aftermath,the school took measures to review the rules and procedures of the race to prevent similar incidents in the future.The two runners involved in the collision received medical attention and were commended for their sportsmanship,despite the unfortunate turn of events.The story of the running race that was marred by a collision is a poignant one.It highlights the unpredictable nature of sports and the need for athletes to be mindful of their actions,not only for their own safety but also for the wellbeing of their fellow competitors.It is a lesson in resilience,as both the runners and the audience learned to appreciate the spirit of the competition beyond the outcome of the race itself.。
辩论2辩稿英文回答:In the multifaceted tapestry of human affairs, the notion of censorship has provoked an enduring debate, with proponents invoking the need to safeguard public morality and prevent the dissemination of harmful or offensive content, while opponents champion the fundamental right to freedom of expression. As I delve into this intricate discourse, I will meticulously examine the arguments for and against censorship, ultimately articulating my stance on this contentious issue.Proponents of censorship often invoke the argument that it is necessary to protect children from exposure to harmful or inappropriate content. They contend that certain forms of speech, such as pornography, violence, and hate speech, can corrupt young minds and lead to deviant behavior. In an effort to shield the innocent, they advocate for the implementation of measures to restrictaccess to such material.Furthermore, proponents maintain that censorship is crucial for maintaining societal harmony and preventing the propagation of harmful ideologies. They argue that hate speech, discrimination, and other forms of divisiverhetoric can incite violence and undermine the fabric of a democratic society. By regulating the flow of information, they seek to create a more cohesive and tolerant environment.However, opponents of censorship vehemently denounceits insidious implications for individual liberty and the free exchange of ideas. They argue that censorship stifles creativity, hinders intellectual progress, and undermines the very foundations of a democratic society. By silencing dissenting voices and controlling the narrative, they assert that censorship creates an atmosphere of fear and self-censorship, where individuals are afraid to express their true thoughts and opinions.Moreover, opponents highlight the inherent subjectivityof censorship, arguing that what one person deems offensive or harmful may be perfectly acceptable to another. They contend that the determination of what constitutes "appropriate" content should not be left to the whims of government or other authority figures but rather should be a matter of individual conscience.In my view, the arguments against censorship ultimately outweigh those in favor. While it is imperative to protect children from exposure to harmful content and maintain societal harmony, these objectives can be achieved through age-appropriate educational programs and parental guidance rather than resorting to censorship. I firmly believe that the fundamental right to freedom of expression is essential for the flourishing of a democratic society and that any restrictions on this right must be carefully considered and narrowly tailored to achieve a legitimate and proportionate objective.In conclusion, I stand firmly against censorship, recognizing its corrosive effects on individual liberty, intellectual discourse, and the very fabric of a free anddemocratic society. I advocate for the protection of children and the maintenance of societal harmony through education and parental guidance, while safeguarding the unalienable right to freedom of expression for all.中文回答:对于言论审查,有人认为有必要保护公众道德,防止传播有害或冒犯性的内容,而另一些人则认为有必要维护言论自由的基本权利。
