Summary of the text
This essay is a piece of argumentation. An argument is a reasoned, logical way of demonstrating that your position, belief, or conclusion is valid. One purpose of argument is to persuade reasonable people to agree with your position. Another is simply to defend your position, to establish its soundness even if others cannot be persuaded to agree. A third purpose of argumentation is to attack some position you believe to be misguided, untrue, or evil, without necessarily offering an alternative of your own. In a good essay of this type, enough evidence should be given to support your arguments. Addressing the claims of the opposition is also an important component in building a convincing argument.

英文Summary写作方法、范例及常用句式
请同学们注意，概要和摘要的写作内容及写作方法是完全不同的。
有的人把概要也称为摘要，切记一定要区分开！概要的英语是：summary, 摘要的英语是：abstract 。
概要是对一篇文章的主题思想的简单陈述。
它用最简洁的语言概括了原文的主题。
写摘要主要包括三个步骤：（1）阅读；（2）写作；（3）修改成文。
第一步：阅读A．认真阅读给定的原文材料。
如果一遍不能理解，就多读两遍。
阅读次数越多，你对原文的理解就越深刻。
B．给摘要起一个标题。
用那些能概括文章主题思想的单词、短语或短句子作为标题。
也可以采用文中的主题句作为标题。
主题句往往出现在文章的开头或结尾。
一个好标题有助于确定文章的中心思想。
C．现在，就该决定原文中哪些部分重要，哪些部分次重要了。
对重要部分的主要观点进行概括。
D．简要地记下主要观点——主题、标题、细节等你认为对概括摘要重要的东西。
第二步：动手写作A. 摘要应该只有原文的三分之一或四分之一长。
因此首先数一下原文的字数，然后除以三，得到一个数字。
摘要的字数可以少于这个数字，但是千万不能超过这个数字。
B. 摘要应全部用自己的话完成。
不要引用原文的句子。
C. 应该遵循原文的逻辑顺序。
这样你就不必重新组织观点、事实。
D. 摘要必须全面、清晰地表明原文所载的信息，以便你的读者不需翻阅原文就可以完全掌握材料的原意。
E. 写摘要时可以采用下列几种小技巧：1) 删除细节。
只保留主要观点。
2) 选择一至两个例子。
原文中可能包括5个或更多的例子，你只需从中筛选一至二个例子。
3) 把长段的描述变成短小、简单的句子。
如果材料中描述某人或某事用了十个句子，那么你只要把它们变成一两句即可。
4) 避免重复。
在原文中，为了强调某个主题，可能会重复论证说明。
但是这在摘要中是不能使用的。
应该删除那些突出强调的重述句。
5) 压缩长的句子。
如下列两例：“His courage in battle might without exaggeration be called lion-like.”可以概括为：”He was very brave in battle.”“He was hard up for money and was being pressed by his creditor.”可以概括为：“He was in financial difficulties.”6) 你还可以使用词组代替整句或者从句。

研究生英语上Summary
研究生英语上Summary第一篇：研究生英语上SummaryUnit1 How to read a book“Some books are to be tasted ,others to be swallowed, and some to be chewed and digested.” Francis Bacon warned readers several hundred years ago.However, what are the criteria for those books to be “chewed and digested?” How to tell good literature form bad literature? On these issues, people don’t seem to have reached an agreement.In the article, Joseph Brodsky first states that people’s life is generally much shorter than books, and that it is important for people to select good books to read.Yet, the author further argues that selecting good books from the ocean of literary works is no easy job;even book reviewers can’t help muc h.In the end, the author suggests that reading poetry is the way to develop good taste in literature, because it is the supreme form of human locution, the moist concise way of conveying the human experience, and offers the highest possible standards for any linguistic operation.Unit2 Recession-proofing Your CareerIn the text, Dr.Barbara Moses describes a new career development paradigm for today’s employees, that is, guaranteed jobs have already become history and it’s high time to engage in a lifelong, self-monitored process which can help to promote and prepare oneself fro a change, esp.during periods of recession.She then suggests some skills which areindispensable when responding to new work trends.She recommends discovering both your overt and covert talents, making sure a wide range of positions are available to you, and never committing to any “hot job” which exceeds either yourinterest or talent.Moreover, being skilled or qualified is not the only criteria.You must be able to “market “yourself, to convince the employer that you are the most suitable candidate for the job, for which purpose you have to establish a social network that can help you make your career decisions “both inside and outside of your professions.” Always follow work trends.Fina lly, psychological elements are also important, so never let yourself down and find a balance between the ambitious Type A and more relaxed Type B.In a word, don’t be under the misconception that your job is always secure and if you work hard you’ll surely get a good job.You must be fully responsible for the future prospects of your chosen career.Unit3 LiesPeople usually have very negative views regarding lies.Liars are frequently criticized, even cursed.Yet this passage exemplifies a different perspective, one which cruelly reveals the fact that everyone tells lies and that lies are indispensable for happiness, perhaps even our very survival.According to the author, lies are consoling elements that can soothe dying patients and help consolidate the requirements of a society.Lies make us feel superior to other species and disguise our mortal doom.Religions abound with myths and tales, which are basically lies that provide human beings with a sense of safety.People need big lies, though they are occasionally taken advantage of, because lying disguises our mortality, our inadequacies, our fears and anxieties, our loneliness in the midst of the crowd.Unit5 Don’t let complexity stop youUN reports say global inequity is still widening over past decades, which poses a serious threat to the prosperity and stability of the world.Whatever disagreements there are, people all over the world seem to agree that, with globalization, it is hightime that such a fundamental problem be solved in a sustainable way, and international cooperation can help in this regard.In this inspiring speech, Bill Gates is calling for a fairer world, one in which people use and apply discoveries for good.“Humanity’s greatest advances are not in its discoveries – but in how those discoveries ar e applied to reduce inequity.” He believes, for higher education, a top mission of policy innovations is to provide students with a more global perspective.Unit6 The riddle of timeSometimes it flies, sometimes it crawls, but it always passes inexorably.We mark it, save it, waste it, bide it, race against it.We measure it incessantly, with a passion for precision.Time is so vitally enmeshed with the fabric of our existence, in fact, that it's hard even to conceive of it as an independent entity, and when we try, the result is less than enlightening.For many people, time is looked upon as a flow like a river, but for theoretical physicists, like Albert Einstein, it is seen as a dimension, like height and width.Throughout history, endless efforts have been put into accurately measuring it, and, consequently, various devices such as calendars and clocks have been devisedNature provides a very accurate timekeeper: the carbon-14 atom, which decays at a known rate during the past 50,000 years.Interesting enough, we human beings also have a body-clock, which is thought to regulate changes in body chemicals, the response of the immune system, and a cyclic rise and fall of heartbeat and blood circulation.第二篇：安徽大学研究生英语上册summary—原创安大研究生英语上册summaryUNIT1Josph Brosky puts himself very clearly in the text.how to reada book.Many books are less limited than ourselves,many writers write a good book through all their lives.therefore,in literature good is defined by its distinction from bad.our readers ought to pick up good books that bring the human predicament into its sharpest possibly focus.the man so called literary criticism all have their limit.the writer accounts poem an a way to develop good taste in literature.he think it as the supreme form of human locution.for it isconcise and offers the highest possible standards for any linguistic operation.A man who used to read poetry may have no interest in bad prose.The writer explain his opinion clearly in the text lies.the text can be divided into three parts.Although we all be taught not tu tell lies since our childhood.we can not deny the fact that people tell lies from time to time for different reason.People may tell white lies ro protect their friend, their friend,their family,or even just for themselves.Religions always tell lies to offer people the hope of life.the government may tell lies to ensure their manipulate of encomy.Lies around us everywhere ,it directs our thoughts and actions everyday and we may never doubt big lies to comfort ourselves.most people want sth moreconsoling than terrible facts.peopleneed big lies because lying disguses our morlatity,our indueques ,our fears and anxiety ,our loneliness in the midst of crowd ,we can nor live without lies.John F.kennedy is the 35th president of America.He gave this speech on his inaugural day.I think this exciting inaugural address can be divided into three parts.In the first part,K commit to do what the oath said although the world is different.Heshou his comfidence to maintain human rights and the sucdess of liberty.He speaks to many kinds of people in the second part.he pledge the loyality offairhful friend,shouws whlcome to the new states ,and pledgethem besr efforts to help the struggling national,he offers a special pledge to the south of America that he hopes to convent good words into good deeds.he renews his pledge of support to the United Nations.he even speaks to their hostile state for peace.In the third pare,he calls for citizen to do sth”Ask not what America will do for you,but whar together we can do for the freedom of man”In the article ,the writer light the necessity for recession-proofing our career and gives his stratergies for recession proofing our career.he thinks our world as a TempWorle.everyone of us may be influenced by it,so all of us should be a career activist.The first strategy is to ensure our employability.he adviced us to currency ability,then create a fallback position in case we have to change our mind-set.knowing our key skills will help us to know ourselves well.being prepared for areas of competence will shorten the time we stepping in a new filed.healso advice us to build a knowledge netork and market ourselves in an opporiate way.As for our thought,we should learn to feel good about ourselves and to act ambitiousResilience is very important for every of us.At last,saty culturally current will benefits us a lot no matter in what case. 第三篇：英语summaryFate is sometimes not very kind to policemen like myself.Take as an example the recent trial in which I was involved.When I arrested the young lad I had felt sure he was guilty I had been following him around for a couple of hours and he conduct himself suspiciously.He had been wandering about and it seemed to me that he was looking for an opportunity to steal.When I arrested him, his casual manner only served to confirm my suspicions.I thought I had at last caught the thief who had beentroubling the area for so long.However, my joy was only temporary.When I saw the brilliant solicitor the boy's father had hired to defend him, I knew we didn't stand a chance.It turned out that the boy was simply a student who was looking for temporary employment before going to university.If only he had been a bit more helpful when we arrested him, he could have saved us all a lot of time and trouble.It's enough to make one turn against students!Despite the vast amount of data available for us to download from the worldwide web, we still face a problem in how to make the best use of it.Data on its own has its limitations.It is only when nature is exposed to fruitful questions that we can hope to uncover her secrets.The evolution of science shows this clearly, with many of the most notable discoveries relying on the ability to view matters rather than simply gathering more facts.In short, half the answer lies in thinking up the right question.T o my mind, in any analysis of the professions, few can match teaching.One needs to be energetic, certainly, for occasionally it seems one hardly has time to catch his breath.It can mean staying up late in order to get lessons prepared on time.Nonetheless, I am convinced that the work is more stimulating than that of my administrative colleagues.I certainly would not wish to switch, even though the pay is higher.With teaching, the pace of life is more varied, allowing greater time for reflection and research.Yet most of all it is the chance to see the spark of a fresh idea taking hold in a student's mind that is the most rewarding aspect of the job, repaying all one's effortsIt is difficult not to be affected by the tale of Sarah Morris.While her physical conditions made it difficult to interpret her speech, from her writing it would be impossible to spot thatshe suffers from such a severe handicap.Writing slowly with the help of a pointer fastened to her head, her maximum writing speed is no more than eight words per minute.Yet she still manages to write extensively on the team she grew up following.Straining her neck in the gloom of her room, surrounded by her computer equipment and a TV set, she has managed to rise above her situation against all the odds.I recall that it was something of an embarrassment to have my son find me so upset on that Wednesday long ago.He had come home expecting to have the place all to himself, only to find me there, frantic with worry about losing my job.I had assumed that I could master typing in just a few sessions, but it took much longer than I had expected.Try as I might, it seemed I just could not catch on to it in time.I suppose I should have enrolled on a correspondence course, as I did when learning to run the nursery, but by then it was too late.I felt helpless and the tension at work was becoming too much to bear, so in the end I just had to accept defeat and change jobs.Not that I gave up wanting to type.I went on practicing and eventually mastered it.The medicines the doctor prescribed for me tasted horrible.They were supposed to bring down my temperature, but when I heard how high it was I was terrified.I thought I was certain to die.I just didn't see how I could possibly overcome the illness.I couldn't stop worrying about it.All day I just gazed into space, feeling miserable.The fever made me shiver and gave my face a flush I couldn't take an interest in anything and felt very detached from everything around me.I thought my father must know I was going to die, but had said nothing, wanting me to keep from thinking about it.Finally I could bear it no longer and asked him how much longer I could live.When he explained my mistake, all my worriesslid away.Only then was I really able to take it easy.I am still trying to figure out why we all behaved so badly on the night my neighbours tried to break into our family bomb shelter.It was frightening for us down there, hearing those we thought of as our friends heading for something to break down the shelter door.Even though we piled up all we could find against the door, I knew it would eventually give way.And it did.Should I hold it against them? After all, their reactions were born of fear and I would probably have behaved the same way in their shoes.Perhaps it would have been fairer to have drawn lots for who got to use the only shelter in the street, but I was never going to let that happen.I was as scared and selfish as the rest.It seems that underneath we are all more aggressive and greedy than we like to think.Many people are hostile to daydreaming, believing that it can interfere with the pursuit of success.They consider that daydreamers will never amount to much in their chosen careers.Recently, however, some experts have begun to argue that indulging in fantasy can have positive benefits.Daydreaming of success, they claim, can contribute to success.One technique they recommend is to picture yourself as you wish to be.Holding this vision clearly in your mind supposedly helps you make it come true.Of course, you should not neglect necessary study or work because daydreaming cannot substitute for hard work.Merely relying on daydreaming will not help you attain your goal.The beauty of the music was in sharp contrast with the reality of the lives led by the singers.Amid all their suffering, a group of Jewish prisoners had found the courage to stage performances of Verdi's Requiem.Despite the difficulties and dangers, they threw themselves enthusiastically into rehearsals, which had to be kept a secret.An additionaldifficulty was that they had only one instrument, an old harmonium.Their greatest triumph came when they performed before an audience containing the infamous Nazi official, Adolf Eichmann.Their voices swelled with passion as they threw in the faces of the Nazis words which sang of how they would have to pay for their crimes.If we look at the process of innovation, we will see how technology feeds on itself, accelerating the pace of technological advance in our own times.Technological innovation is comprised of three stages: invention, application and diffusion.One of the most important characteristics of advanced technology today is the fantastic speed that occurs between each of these stages.For example, nowadays the time it takes to put ideas to work has been greatly reduced.The progress in transportation is a case in point.Likewise, the time between the application and diffusion stages has been radically shorted.This accounts for the acceleration of present-day technology.And this, in turn, generates more feasible ideas.What sort of future will this process conjure up for us? Will the pace of change exceed our ability to cope with it? Or is it one of our characteristics that we have an impressive ability to adapt to change, no matter how frequent?DictationOne of the ways you can encourage children to be creative is to talk things over rather than to give instructions or make a model when they ask for help.If you show a child how to draw a flower or a person, they will try to draw one just like yours.This can be frustrating because no matter how hard children try, their pictures will not be as “good” as yours because they do not have the skill that you have.Chances are that children will compare the two pictures and not be happy with their own.Theymay even decide not to try.Be creative yourself and think of ways to encourage children's creativity.Baseball is America's national sport, played mainly by men.It developed in the mid 19th century from the British games of rounders and cricket.Baseball is also popular in Japan and several Latin American countries, and has been an Olympic sport since in 1972.Softball is similar but uses a large, softer ball and is popular with women.Many Americans play baseball for fun because players do not have to be strong like football players or tall like basketball players.Some people think baseball is too slow, but the team managers often change their players and plans during the game, and there are many exciting plays.Many American families enjoy going to a Sunday afternoon double-header, that is, two games between the same two teams in one day.The Terezin concentration camp was established by the Nazis in an 18th century fortress in Czechoslovakia on November 24, 1941.More than 150,000 Jews passed through the camp during its four-year existence, which was used as a holding area for eventual murder in Auschwitz.By 1943, rumors began circulating in the international community that the Nazis were exterminating Jews in gas chambers, and that the conditions of the concentration camps did not permit survival.The Nazis rebuilt parts of this camp to serve as a “showpiece” for propaganda purposes.Flowers were planted there.Shops, schools, and a cafe were built.When an investigating commission of the International Red Cross came to visit, they did not see a typical concentration camp.In July 1944 the Nazis made a documentary propaganda film about life in this camp.After the movie was completed, most of the Jewish “actors” were shipped to their death at Auschwitz.第四篇：summary学术英语A summary of Text 12Title:How Radiation Threatens HealthAuthor:Nina BaiSource:Scientific American, 15 March, 2010Summary:The radiation leaks at Fukushima makes people feel worried, and it’s necessary to know that the health effects caused by radiation exposure depend on its level, type and duration.Every person is exposed some background radiation from natural but only beyond this level people can get radiation sickness.At the same time, the radiation which takes different forms is produced by different heavy isotopes.On the other hand, the exposure time is so important that high single dose of radiation can do much more harm to human than the same dosage accumulate st but not least, the government should remember the Chern obyl’s lessons but we’d better not do too many extra measures to make people feel scared.(124 words)第五篇：国际贸易英语沃尔玛summaryWal-Mart : The high cost of low priceThe video has exposed the truth behind Wal-Mart’s low price,which global consumers must know.Low price is the key advantage for Wal-Mart to attract consumers to go shopping there.Now it has become one of the biggest retail chains in the world, making great fortune, creating countless jobs , promoting the global economy and so on.it is an amazing and successful company.However，it has led to negativeconsequences.The Wal-Mart has already 5000 chains in the whole world, and the quantity is still growing.once there is a new chain to be opened, several stores in the streets which is near it will close.most of these stores is managed by family, which is commonphenomenon lasting for a long time in towns of America.When their family estates which was poured into painstaking effort by them disappearing , they are sad.Meanwhile they have to choose a new way to support the family.It is the reason that so many citizens working together to fight against Wal-Mart stores’ settling down in the town.We are happy to see that the video ends with views of community leaders who have prevented Wal-Mart stores from being built in their communities.They have gotten the victory!To support the low cost, all the manufacturing industries are outsourced to the developing countries.A lot of local workers are working for long hours with low salary and the extra working hours willnot be paid often.Their dormitories are crowed and without air-conditioner.This also happens to staff in America.According to related data, the wage rate of the workers in America is lower than the lowest living level.The manufacturing industries’ outsourcing has bad impact on the local environment.Low prices at the first sight, but when you look into, you can have a different view.Do you still choose Wal-Mart for its low price when you go shopping?。
