英语四级作文优秀范文背诵英语四级作文优秀范文背诵Pollution Air pollution is one of the major problems of the modern world.A great deal of energy is needed to run the factories of modern industrial nations.Automobile,trains,planes and busses need energy,too.Nearly all of this energy is produced by burning fuels.The burning produces wastes,some of which remain in the air,causing air pollution.Scientists are finding ways to stop air pollution especially in big industrial areas and densely-populated cities.They are studying new ways of generating electricity that may be less damaging to the environment.In the meantime,many power plants are being modernized to give off less polluted material.Also,engineers try to design and locate new power plants to do minimum damage to the environment.However,it may be that we still have a long way to go before we have a clean world.Nearly all of the countries are trying hard to prevent and control air pollution.There indeed seems to be no end to tasks that environmentalists will be required to do.People will continually find new ways to control pollution.Environmental Protection Today the quality of our natural environment has become an important issue.The world population is rising so quickly that the world has become too crowded.We are using up our natural resources and at the same time polluting our environment with dangerous chemicals.If we continue to do this,life on earth cannot survive.Concerned people have made some progress in environmental protection.Governments of many countries have established laws to protect the air,forests and sea resources and to stop environmental pollution.Still more measures should be taken to solve environmental problems.People should be further educated to recognize the importance of the problems,to use modern methods of birth control,to conserve(保存)our natural resources and recycle(再循环)our products.We are sure that we can have a better and cleaner place in the future.Computer The computer is widely used in all fields of society.Today,wherever you go,you will find computers being used.For example,computers are used in universities,large corporations,and small offices,etc.It has even entered the homes of ordinary people.As it is able to store and process a large amount of information,the computer bring about great convenience and high efficiency to people of all walks of life.Computers can help people in different ways.For example,computer help scientists in analyzing data and doing complex calculation.For another example,computers are made use of by engineers in designing a plane,or a spaceship.Besides,computers may also play a great role in helping children with their lesson.Whatever you are doing,you many find computer a useful aid.However,the computer must be designed and instructed by man.What is more,it is true that computers can make decisions,but they need detailed instructions and programs prepared by humans to operate.Therefore,the computer can never replace the human brain.Travelling It is exciting to visit different places.As you travel,you will see beautiful sceneries typical of the region.Besides,you can meet and make friends with people of different colors and races.Finally,you can get to know the customs and living habits of the local people.Today people are so fond of travelling that tourism has become one of the faster growing industries in most countries.The main reason why people travel is,perhaps,for pleasure.For example,having worked hard throughout the weekdays,people will find a widened trip to the nearby mountains or beaches a real relaxation.For another example,spending an annual holiday travelling abroad is an especially satisfying experience for those who do not have much of an opportunity to be away from their homelands.When people return from their travel,they will generally feel fresh and energetic,ready to work harder.Travelling is also one of the best means for learning.You may have read or heard about something but you can never get an accurate picture of it until you see it for yourself.Seeing is believing.Furthermore,if you area careful observer,you can learn much during your travel about the geography,biology,and history of the places you visit.No matter how well educated you are,there is always a lot for you to learn through travelling.The knowledge acquired from travel,as you will have found in your life,is no less valuable than that from any influential reference book.How To Deal With Depression In recent years,more and more people have suffered from depression.With the increasingly fierce competition,more and more people are bearing great pressure from study,work and life.Under great pressure,many people begin to become sad,hopeless and finally suffer from depression.Depression has brought great bad influence on onestudy,work and life.In fact,depression affects not only ones mind but also his body.Those with severe depression even unable to continue their work or carry out normal activities of depression.The symptoms mainly include feelings of sadness,hopelessness,not wanting food and trouble sleeping.Besides,depression is linked to many other diseases,like heart disease,Whats worse,deprssion is one of the main courses of peoples suicide.Considering the bad effects of depression,it must be taken more seriously.For those patients with depression,first of all,it is important to accept treatment timely instead of covering or ignoring the disease.Besides,people shuold learn to release pressure and keep a pleasant mood.Actually,the best treatment is a combination of medication and psychological help.Only in this way can people reduce the chance of suffering from depression.Health and Life As the saying goes,you dont know what happiness is until you lose it you dont know what health is until you are ill.“Health is of vital importance to life”sounds like a cliche to everyone,but it is absolutely true.The negligence of the delicate balance of your body and soul,the harmful habits such as smoking,excessive drinking and burning mid-night oil will catch up with you someday.How many big plans are interrupted by bad health!Even a normal life is unimaginable without the guarantee of health.How to keep fit is an eternal topic of diversity and controversy.Regardless of all the different suggestions poured from all kinds of sources,one should do at least two things for him/herself.First,hold an active and optimistic attitude toward life and maintain a mental well-being.Second,live a regular life and keep a balanced diet.Anyway,a healthy life is within reach when you begin to adjust your mind and body.Students Part-time jobs There are many advantages for a student to have a part time job.For instance,it helps him to realize that no success comes from nothing.It enables him to be independent and builds up his self-confidence.Therefore,part-time jobs can get the students out of the ivory tower and give them the opportunity to know more of himself and of his personal value in society.As everything has two sides,the disadvantages cant be ignored.Part-time jobs cut into students study time;some even become so preoccupied with making money that they ca t focus their attention on studying.In the end,the students may fall behind or fail in their studies.In my opinion,students can choose to take up a job according to their own situation.The most important thing is for him to keep a good balance,put his study on top of the list and assign an adequate amount of time to it.Popular Sports in China Sports are flourishing in china now.More and more people are willing to take part in sports of different kinds,such as table-tennis,football,volleyball,and so on.Every year there are many matches played on the city,provincial or national level.Sports are no longer limited to a few professional players.Early in the morning people may be seen doing exercise.Martial arts(like Chinese boxing or swordplay)which formerly were cultivated for self-defense,now have become a form of physical exercise and are practiced in parks,streets,gardens,or on campuses.In addition young and old people are also often seen running in order to build up their bodies.China promotes sports to enhance the physical condition of its people;she is formulating policies to provide encouragement of this activity.She awards prizes to the excellent players for the best records both in china and the world.In the world the Chinese have become a strong people instead of“the weaklings of East Asia”Wealth and Happiness Everybody wants to get wealth.In todays material world,making money or becoming wealthy symbolizes a persons success and capability.Many people just make every effort,pay any price to attain greater wealth.With money,they can but nice,large apartments in nice neighborhood;with money,they can own stately luxury cars.Wealth seems with money,they can own stately luxury cars.Wealth seems to bring all happiness in life.In my opinion,people cannot do anything without money,but money is not everything.What money will bring you depends on your personal belief and goal in life.If you are kind enough to help others,especially the poor,money is a good thing to you.With it,you can do much more for the benefit of people and your country,and it will and to your own happiness.If you want money just for your own needs,youll never be satisfied or happy.In a word,you should have money spent for more people,only then can money be the source of your happiness.Is Failure a Bad Thing?Failure is what often happens.It is everywhere in our life.Students may fail in exams,scientists may fail in their research work,and athletes may fail in competitions.Although failure happens to everyone,attitudes towards failure are various.Some people dont think their failure is a very important thing at all.So they pay no attention to it.As a result,they will have the same failure a period later.Some people think themselves are fools and lose their hearts in everything after they get a failure.Consequently,they spend their time and energy on useless things and they may really be fools as they have thought.Other people are quite different from the two kinds of people mentioned above.Instead of being distressed and lost,they draw a lesson from every failure and become more experienced.After hard work,they will be successful in the end.It is said that failure is the mother of success.Success will be gained after times of failures so long as we are good at drawing lesson from our failures.In my opinion,failure is not a bad thing,the really bad thing is taking a failure as failure or even lose our heart after failure.Modernization of Family Life With the rapid development of the society,family life is becoming modernized.Years ago,people considered owing radios,sewing machines,watches and bicycles as being modernized.But in recent years,almost all families have TV sets,refrigerators and washing machines.It is very common to see people ride motorcycles or even drive private cars and more and more families have telephones,computers and air-conditioners.The modernization of family life brings us convenience and comfort.One may enjoy TV or radio programs,communicate with his friends through telephone or work with his computer while his washing machine,refrigerator and air-conditioners are running.And by car or motorcycle one can quickly reach wherever he wants to go.In spite of this,these modern facilities also bring us disadvantages.For example,radiation from TV sets and computers is harmful to our health;improper driving of cars and motorcycles becomes the major cause of traffic accidents.The quietness of a family is often disturbed by a falsedialing or unwelcome phone call.But it is believed that these disadvantages will be disposed of with the improvement of modernization and our life will be more healthy and more comfortable.Ideals Everyone has his ideals.A businessman wishes to make greater profit;a farmer expects bumper harvests;a student tries to learn more and better.And everyone strives,with more or less effort,to realize his ideal.One should be sensible about whether his ideal is well founded or not.If it is,one has to plan and work hard for its realization.Effort,skill and persistence are all necessary.And very often,one has to get help from others,including advice and support in one form or another.My ideal is to become a doctor,It is said that the field of medicine is a well-paid profession,but I take it as a lofty profession entrusted with saving peoples lives.To realize my ideal I have concentrated on laboratory work to develop the analytical skills necessary to become a qualified doctor.I am sure I will realize my ideal if I persevere in this pursuit.Competition Competition makes people original and creative.It very necessary to compete if human society wants to advance.(Even animals compete for survival.)Without it,we would become lazy and nobody would rake any responsibility.When three monks live together,there will be no drinking water.This Chinese proverb vividly describes why Chinas productivity was so low before Mr Deng came to power.At that time,we had the so-called planned economy.There was no competition at all.So neither farmers nor workers worked hard.China was on the edge of collapse.Competition can stimulate people to try their best to do anything.For example,in 100-meter race,each sportsman runs as quickly as possible,trying to win the champion.The same things happen in our society and in our daily life.If a company wants to surpass others,it must compete with them.It must raise its efficiency.All the companies doing this will no doubt benefit the whole society and the whole human race.Being a student,I must compete with other students in our studies.I must study hard in all the fields so that I can be a useful man when I enter the society after graduation.Energy Resources China is rich in various energy resources.Coal and petroleum,for instance,are two major ones.They are essential in developing the countrys industry,science and technology.China has done a great deal in the past few decades to raise its output of coal and petroleum.Three energy resources are being used up rapidly,With the building of four modernization,new industrial and science projects are springing up like bamboo shoots after rain.They are all big consumers of energy resources.Besides there has been considerable waste in the utilization of these resources.To avoid an energy crisis in the future,the government must take certain measures.First,it should let people know the importance of saving energy.Second,efforts should be made to develop new energy resources,such as solar energy,geothermal(地热)energy and so on.We have reason to be optimistic in this respect.The Brain and the Computer Some recent developments in the computer industry make scientists predict that the gap between human beings and machines will be closed about the year 20000.To understand the significance of this prediction let us compare the human brain with existing computers.The brain consumes electrical energy at the rate of 25 watts and occupies a volume of one tenth of a cubic foot.The brain houses between 10 billion and 100 billion items of information.Every brain cell is directly connected to many other cells.As a result,the cells in which information is stored can communicate with thousands of other cells.However,the computer consumes 1000,000 watts of electrical power and occupies hundreds of cubic feet of space.Its million items of immediately accessible information.In contrast,the computer memory is like a cell of pigeonholes,with no thinking capacity and no connections elsewhere.In a word,the electronic brains are hopelessly inadequate in comparison with the human brains.Choosing an Occupation Every one faces the problem of choosing an occupation after graduation from college or university,which plays a vital role in his life.An appropriate occupation makes a man work with zest(热情)and vigor,as well as contribute to his country.To make a wise choice,two important things should be taken into consideration.One is the interest,the other,the demands of people and society.Only if the two aspects are connected,can a man show his talent and ability to the best advantage.If the two conflict,the former should be under the latter,for the peoples interests are more important than the individuals.In regard to my choice in the future,I am fond of learning foreign languages;what is more,with the implementation of the Open-Door Policy,exchange between home and abroad in economy and culture has been growing significantly,thus Im determined to be a qualified interpreter.Opening-door Policy is the Only Way to Make China StrongModern Chinese history leads us to the conclusion that socialism,not capitalism is best for China.But how a socialist China should look at capitalism and more importantly,make use of the better side of capitalism for its own advantage is of vital(至关)importance to the country.As far as our countrys economic construction is concerned,taking advantage of the part of capitalism that is useful to us means we need to develop foreign trade,introduce advanced technology and better management,and make use of foreign funds.It also means we can absorb some of the economic theories,and make use of those economic policies,methods and measures that comply with(遵循)the law of mass production and a commodity economy.By opening our windows wider to the outside world,people can learn more about other peoples and learn to make sensible judgments.Absorbing the better part of the cultures of other people to enrich ourselves is the best way to safeguard our socialist culture.So taking advantage of capitalism and stepping up economic reforms is the only way to make China strong.Closing the county to international exchanges will only keep it weakWorld Population Explosion The human race has experienced a consistent increase in population since the beginning of its history.Famine and disease have done little to offset(抵消)this steady increase.Too many people are added annually to the population of the world.So both the causes of population increase and the results of having more people are worth careful study.Culture evolution is the major factor responsible for population increase.Early in human development,people invented tools to hunt animals.Later they built shelters to protect themselves.Step by step,they made life easier.As a result,fewer died from natural forces,such as harsh climate and disease.In the past,when population grew,there was unexplored territory to inhabit.But now,almost all the habitable land has been explored.The worlds population may reach 8.7 billion in 2033.It is clear that world population is a serious issue that needs careful attention.Human beings are unique to solve problems through cultural evolution.(发展)Facing the world population explosion in the near future.We must carry out the birth control program in order to save the mankind and save the world.Automobiles Automobiles,as a product of modern civilization,have been playing a vital part in the daily activities of human society.Industry needs automobiles for farming as well as transportation.Every day,automobiles drive people to and from work.On weekends automobiles take families for joyful outings.And during holiday seasons,automobiles fill the highways everywhere,even in remote areas.It could be said that the wheels of automobiles move society forward.But automobiles have also given rise to a series of problems.For example,cities are overcrowded with automobiles.They create a lot of noise and traffic accidents which disable(伤残)or kill many people each year.Worst of all perhaps is the air pollution caused by the exhaust gases produced by automobiles.Some of the gases are highly toxic(有毒的)and a serious health hazard.Importance of Education China,as a developing country,is determined to catch up with and even surpass the developed ones.I think that one of the best possible ways to do so is to give first prio
