篇1:以公共利益为话题的英语作文
全文共 2836 字
+ 加入清单The Scandinavian countries are much admired all over the world for their enlightened social policies. Sweden has evolved an excellent system for protecting the individual citizen from high-handed or incompetent public officers. The system has worked so well, that it has been adopted in other countries too.
The Swedes were the first to recognize that public officials like civil servants, police officers, health inspectors or tax-collectors can make mistakes or act over-zealously in the belief that they are serving the public. As long ago as 1809, the Swedish Parliament introduced a scheme to safeguard the interest of the individual. A parliamentary committee representing all political parties appoints a person who is suitably qualified to investigate private grievances against the State. The official title of the person is Justiteombudsman, but the Swedes commonly refer to him as the J. O. or Ombudsman. The Ombudsman is not subject to political pressure. He investigates complaints large and small that come to him from all levels of society. As complaints must be made in writing, the Ombudsman receives an average of 1, 200 letters a year. He has eight lawyer assistants to help him and he examines every single letter in detail. There is nothing secretive about the Ombudsmans work, for his correspondence is open to public inspection. If a citizens complaint is justified, the Ombudsman will act on his behalf. The action he takes varies according to the nature of the complaint. He may gently reprimand an official or even suggest to parliament that a law be altered. The following case is a typical example of the Ombudsmans work.
A foreigner living in a Swedish village wrote to the Ombudsman complaining that he had been ill-treated by the police, simply because he was a foreigner. The Ombudsman immediately wrote to the Chief of Police in the district asking him to send a record of the case. There was nothing in tthe record to show that the foreigners complaint was justified and the Chief of Police strongly denied the accusation. It was impossible for the Ombudsman to take action, but when he received a similar complaint from another foreigner in the same village, he immediately sent one of his lawyers to investigate the matter. The lawyer ascertained that a policeman had indeed dealt roughly with foreigners on several occasions. The fact that the policeman was prejudiced against foreigners could not be recorded in the official files. It was only possible for the Ombudsman to find this out by sending one of his representatives to check the facts. The policeman in question was severely reprimanded and was informed that if any further complaints were lodged against him, he would be prosecuted. The Ombudsmans prompt action at once put an end to an unpleasant practice which might have gone unnoticed.

Spring is the best season of a year. The weather gets warmer and warmer. My
classmates and I took a one-day sightseeing tour around our city. The scene was
very beautiful. But when we saw the rivers along our city, I felt very sorry and
thought a lot.
With the development of modern industry and agriculture, more and more
waste is being poured into rivers. It has caused serious pollution. The rivers
are becoming so dirty that nothing can live in them. The rivers are giving off a
terrible smell.
We make an urgent appeal that measures should be taken to cope with the
situation. Our government should build various facilities such as sewage
treatment plant and encourage scientists to work out more and better ways to
reduce water pollution.
Water is the source of our lives. It is very important to protect the

+ 加入清单Happinessmeans different things to different people. For example, some people believe that if they have lots of money, they will be happy. They believe that if they are wealthy, they will be able to do anything they want, which means happiness. On the other hand, some people believe that holding a high position in the government is happiness. In this way, you have not onlymoney, but also many other things which cant be bought by money.
However, other people believe that having lots of money is not happiness nor is holding a high position in the government. These people value their beliefs, or their intelligence, or their health. They think these can make them happy.
For me, happiness is closely tied to my studies, my work and my family. When I made great progress in my studies, when I made contributions to the society through my work, when all the members in my family live in harmony, sharing good and sad times, I was happy. Although the definition of happiness depends on each individual my "wealth" of happiness is in my studies, my work, and my family.
篇13:以勇气为话题的英语作文
全文共 1783 字
+ 加入清单导语:勇气是一个人在面对死亡时冷静和控制的能力。下面是yuwenmi小编为大家整理的优秀英语作文,欢迎阅读与借鉴,谢谢!
Hemingway often thought of courage as a persons ability to be calm and controlled in the face of death. His theme is presented in his novel "For Whom the Bell Tolls?" the story "The Old Man and the Sea" and in our textbook "A Days Wait". By misunderstanding a different thermometer the boy thought he was running a high fever and would soon die. But he took his death bravely and waited quietly for it. The boy showed us he had courage.
I think such a definition of courage is far from enough. Courage should not be limited and related only to death. In ordinary life there are common things that also show a persons courage. For example, on a bus trip, a thief was trying to steal a girls purse. Some people saw it, but kept quiet. They were afraid to be revenged by the thief. The brave stood out and stopped the thief.
Courage means truth and justice to me. The person in a high position often hear songs in praise of him. Some people are sincere. Some are only flattering the superior in their own favor. The leader also needs courage to welcome criticism as well as those who have the courage to criticize him. Such courage may come from mutual understanding. I think a man of courage will value truth and justice, and not hesitate in his actions to do what he thinks is right, There is no such word as fear in his dictionary.
【参考译文】
海明威常常认为勇气是一个人在面对死亡时冷静和控制的能力。他的主题是在他的小说“丧钟为谁而鸣?”“老人与海”的故事和我们的教科书“一天的等待”。由于误解了另一个温度计,男孩以为他发高烧,很快就死了。但他勇敢地死了,静静地等待。男孩告诉我们他有勇气。
我认为这样一个勇气的定义是远远不够的。勇气不应仅限于死亡。在日常生活中也有一些常见的东西,也显示一个人的勇气。例如,在公共汽车上,一个小偷试图偷一个女孩的钱包。有些人看到了,却保持沉默。他们害怕被报复的小偷。勇敢的人站出来制止了小偷。
勇气对我来说意味着真理和正义。那个地位高的人经常听到赞美他的歌。有些人是真诚的。有些人只为了自己的利益奉承上级。领导人也需要勇气来欢迎批评,以及那些有勇气批评他。这种勇气可能来自相互理解。我认为一个有勇气的人会重视真理和正义,在他的行动中毫不犹豫地去做他认为正确的事,在他的字典里没有恐惧这个词。

Secondly, even worth mentioning is that many young boys and girls couldnt attend classes and courses instead of traveling to some sceneries and sight places or doing other things only to turn out them loved each other temporarily. Thirdly, especially to most of freshmen, please dont be influenced by the phenomenon that a number of students who finds anther half called by them selves proudly, because I think persons are different from each other, different characters, backgrounds and aims. But there is one point to obey if you actually want to have an attempt the feeling for love at first sight: it is , whenever you and I am, the learning and the work is the most principle rather than love is the first and work second, for we arent children and teenagers anymore, in the future society needs a comprehensive qualifications, profound and extensive knowledge persons, meanwhile in college you are in the state of half foot to society which time is a most important process to exercise and experience before stepping to complicated and complex society, and therefore we are supposed to spend much time in learning instead.
What are mentioned above are only my opinions, believing that others have more perfect for falling in love in college.If you are falling love with somebody in college right now,please do yourself to be a excelent college student.

The seeds,and the power to grow them,are contained in the most awesome machine ever created:the human mind.Successis a choice and not a chance.You were born a winner.You were born rich.You can be a success if only you make the righy choice.
You cannot be successful without first developing your self-esteem.Your level of self-esteem is always based on the degree of control that you are able toexercise over yourself,and thus over your life.People with low self-esteem are people who do not believe that they have any power,or responsibility for their lives.They are the perennial victims and martyrs.They are leaves tossed by the winds of chance blown about with any sudden change in the weather.
You can exercise control ove your life only to the degree that you believe that you are responsible for everything that happens in your life.Failures think that everything happens by accident and chance.Successful people realize that they are responsible.
Everything happens as a result of something.If we can identify the cause,we can control the effect.We are responsible for what we choose to think and believe.One generally rises th the level that one expects.We are responsible for setting our expectations.Our success is dependent upon ur level of confidence.
If you associate with positive-thinking people,you are definitely going to achiece success.On the contrary,the opposite happens.We are responsible for finding,planting,and nurturing the seeds that contain future victory,born from setbacks.
In short,in all areas of your life,whether they are financial,physics,emotional,or spiritual,your are responsible.Once you recognize this,accept it,and firmly believe it,you are on the road to success.

I have a dream that one day every vally shall be exalted, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together.
Wow, what a dream it has been for Martin Luther King. But the changing world seems telling me that people gradually get their dreams lost somehow in the process of growing up, and sometimes I personally find myself saying goodbye unconsciously to those distant childhood dreams.
However, we meed dreams. They nourish our spirit; they represent possibility even when we are dragged down by reality. They keep us going. Most successful people are dreamers as well as ordinary people who are not afraid to think big and dare to be great. When we were little kids, we all dreamed of doing something big and splashy, something significant. Now what we need to do is to maintain them, refresh them and turn them into reality. However, the toughest part is that we often have no ideas how to translate these dreams into actions. Well, just start with concrete objectives and stick to it. Don’t let the nameless fear confuse the eye and confound our strong belief of future. Through our talents, through our wits, through our endurance and through our creativity, we will make it.
Hold fast to dreams, for if dreams die, life is a broken-winged bird that cannot fly. Hold fast to dreams, for when dreams go, life is a barren field frozen with snow. So my dear friends, think of your old and maybe dead dreams. Whatever it is, pick it up and make it alive from today.
篇19:以冬眠为话题的英语作文

+ 加入清单Hibernation is more than sleep. It is a very deep sleep.The animals temperature drops to just over zero centigrade,and its heart beats very slowly. People who find hibernating animals asleep often think that they are dead: the body feels very cold, and the creature may breathe only once every five minutes. A hibernating animal cannot feel any pain. You can touch it, or even pull its tail, without causing it to move or wake up. In its hibernating state it can even live in a poisonous atmosphere for a long time without any ill effect.
Hibernating in this way, the animal can sleep all through the winter. You might wonder how it manages to live without eating for so many months. The answer lies in two facts. Thefirst is that it has stored supplies of fat in its body during the summer and autumn. The second is connected with the main use the body makes of food -- to supply the energy for movement. We have seen that hibernating animal reduces movement to far below the ordinary level. Even the movements of the heart and lungs are greatly reduced. The animal hardly makes any movement, hardly use any energy, and hardly needs any food.
Some animals, including some bears only half hibernate.That is to say, they sleep during the winter, but their sleep is not deep and their body temperature does not drop, as they are warm-blooded animals. In the antumn the bear eats and eats and becomes very fat. His hair grows longer. Soon he has a thick covering of fat and fur. In November he finds a place to lie down and goes to sleep. On warm winter days he may think spring has arrived; he gets up and walks around. When he sees that the snow is still thick on the ground, he quickly goes to sleep again.
