The host journalist, however ,emphasized the political influence of his performance. The argument ended up rousing anger from both parties. The incident underlined how sensitive some people can be to what others find funny. It also showed how important comedians have become to politics.你听说过斯图尔特乔恩吗？他目前是电视上最受欢迎的漫画家之一。

Unit 10TextDo you view work as a burden or an opportunity? Are you the kind of person who looks for ways to save your energy or the kind that finds spending your energy satisfying? Why do people like to complain about work? Find the answers to question like these in the following essay.WHY PEOPLE WORKLeonard R. SaylesJobs and work do much more than most of us realize to provide happiness and contentment. We're all used to thinking that work provides the material things of life -- the goods and services that make possible our modern civilization. But we are much less conscious of the extent to which work provides the more intangible, but more crucial, psychological well-being that can make the difference between a full and an empty life.Historically, work has been associated with slavery and sin and punishment. And in our own day we are used to hearing the traditional complaints: "I can't wait for my vacation," "I wish I could stay home today," "My boss treats me poorly," "I've got too much work to do and not enough time to do it." Against this background, it may well come as a surprise to learn that not only psychologists but other behavioral scientists have come to accept the positive contribution of work to the individual's happiness and sense of personal achievement. Work is more than a necessity for most human beings; it is the focus of their lives, the source of their identity and creativity.Rather than a punishment or a burden, work is the opportunity to realize one's potential. Many psychiatrists heading mental health clinics have observed its healing effect. A good many patients who feel depressed in clinics gain renewed self-confidence when gainfully employed and lose some, if not all, of their most acute symptoms. Increasingly, institutions dealing with mental health problems are establishing workshops wherein those too sick to get a job in "outside" industry can work, while every effort is exerted to arrange "real" jobs for those well enough to work outside.And the reverse is true, too. For large numbers of people, the absence of work is harmful to their health. Retirement often brings many problems surrounding the "What do I do with myself?" question, even though there may be no financial cares. Large numbers of people regularly get headaches and other illnesses on weekends when they don't have their jobs to go to, and must fend for themselves. It has been observed that unemployment, quite aside from exerting financial pressures, brings enormous psychological troubles and that many individuals deteriorate rapidly when jobless.But why? Why should work be such a significant source of human satisfaction? A good share of the answer rests in the kind of pride that is stimulated by the job, by the activity of accomplishing.Pride in AccomplishmentThe human being longs for a sense of being accomplished, of being able to do things, with his hand, with his mind, with his will. Each of us wants to feel he or she has the ability to do something that is meaningful and that serves as a tribute to our inherent abilities.It is easiest to see this in the craftsman who lovingly shapes some cheap material into an object that may be either useful or beautiful or both. You can see the carpenter or bricklayer stand aside and admire the product of his personal skill.But even where there is no obvious end product that is solely attributable to one person's skill, researchers have found that employees find pride in accomplishment. Our own research in hospitals suggests that even the houskeeping and laundry staffs take pride in the fact that in their own ways they are helping to cure sick people -- and thus accomplishing good deal.We're often misled by the complaints surrounding difficult work; deep down most people regard their won capacity to conquer the tough job as the mark of their own unique personality. Complaining is just part of working. After all, how else do you know who you are, except as you can demonstrate the ability of your mind to control you limbs ad hands and words? You are, in significant measure, what you can do.Some are deceived into thinking that people like to store up energy, to rest and save themselves as much as possible. Just the opposite. It is energy expenditure that is satisfying. Just watch an employee who must deal with countless other people because his or her job is at some central point in a communications network: a salesman at a busy counter, a stock broker on the phone, a customer representative. They will tell you how much skill and experience it takes to answer countless questions and handle various kinds of personalities every hour of the day. Not everyone can interact with such persistence and over long hours, but those who do, pride themselves on a distinctive ability that contributes mightily to the running of the organization.But work is more than accomplishment and pride in being able to command the job, because except for a few craftsmen and artists most work takes place "out in the world," with an through other people.Esprit de corpsPerhasps an example will make the point:I remember viewing a half dozen me in a chair factory whose job it was to bend several pieces of steel and attach them so that a folding chair would result. While there were ten or twelve of these "teams" that worked together, one in particular was known for its perfect coordination and lightning-like efforts. The men knew they were good. They would work spurts for twenty or thirty minutes before taking a break -- to show themselves, bystanders and other groups what it was to be superbly skilled and self-controlled, to be the best in the factory.When I talked with them, each expressed enormous pride in being a part of the fastest, best team. And this sense of belonging to an accomplished work group is one of the distinctive satisfactions of the world of work.One further word about work group satisfactions. Unlike many other aspects of life, relationships among people at work tend to be simpler, less complicated, somewhat less emotional. This is not to say there aren't arguments and jealousies, but, on the whole, behavioral research discloses that human relations at work are just easier, perhaps because they are more regular and predictable and thus simpler to adjust to than the sporadic, the more intense and less regular relationships in the community. And the work group also gently pressures its members to learn how to adjust to one another so that the "rough edges" are worked off because people know they must do certain things with and through one another each day.Beyond the team and the work group, there is the organization, whether it be company or hospital or university. The same pride in being part of a well-coordinated, successful unit is derived from being part of a larger collectivity. Working for a company that is thought of as being part of the best in the community can provide employees with both status and self-confidence.They assume, usually with good reason, that others regard them more highly, even envy them, and that they are more competent than the average because of this association with a "winner," a prestigious institution. We in truth bask in the reflected glory of the institution, and we seek ways of asserting our membership so that others will know and can recognize our good fortune. New Words。
Unit 1攻势已经持续了三天，但是我们并没有取得多少进展。
我们在前线与敌人交战的部队遇到了强力的抵抗。
师长（DIVISION COMMANDER）命令我们营（BATTALION）绕到敌人后方发起突然袭击。
然而，要绕到敌人后方，我们必须越过一片沼泽地（MARSHLAND）。
我们很多人担心会陷入泥潭之中。
我们营长决定冒一下险。
我们在夜幕掩盖下出发，不顾困难，奋勇向前。
幸运的是，夜间温度突然下降到摄氏零下20度，烂泥地都结上了冰。
由于这寒冷的天气，我们于天亮前到达并从敌人后方发起进攻。
这一下扭转了战局。
敌人没有戒备，不久便投降了。
The offensive had already lasted three days,but we had not gained much ground.Our troops engaging the enemy at the front were faced with strong/fierce/stiff resistance.T he division commander instructed our battalion to get around to the rear of the enem y and launch a surprise attack.To do so,we had to cross marshland and many of us we re afraid we might get bogged down in the mud.Our battalion commander decided t o take a gamble.We started under cover of darkness and pressed on in spite of great difficulties.By a stroke of luck,the temperature at night suddenly dropped to minus 20 degrees Celsius and the marsh froze over.Thanks to the cold weather,we arrived at ou r destination before dawn and began attacking the enemy from the rear.This turned t he tide of the battle.The enemy,caught off guard,soon surrendered.Unit 2汽车在二十世纪改变了世界，尤其是在美国和其他工业国家。

第一单元当我想起这个世界上的人，我认为我的父母真的很不错。
在普通人当中他们是真正的圣人。
我是我父母收养的10个孩子之一。
他们把我们每一个从一个贫穷孤独的生活中解救出来。
他们几乎不能阻止他们自己带回家更多的孩子来照顾。
如果他们有这资源，他们当然会这样做！大多数人并不知道自己有多感激某些人直到他们去世。
我姐姐、哥哥和我不想让这个发生在我们身上，在我们对父母说“谢谢”之前。
尽管我们已经长大了，并且散步在全国，为了谢谢父母，我们一起回来了。
我的哥哥Tom承担了组织这件大事的任务。
每周周五晚上，在过去的20年爸爸和妈妈都会在同一个餐馆吃特别的火腿晚餐。
那就是我们在他们不知道的情况下等待的地方。
当我们第一眼瞥见他们穿过大街，我们都躲在一张大桌子的下面。
当他们进来的时候我们都跳出来并且大喊“爸爸，妈妈；谢谢！”我的哥哥Tom送给了他们卡片作为礼物，我们都拥抱了。
我爸爸指出，他知道我们一直躲在桌子下面。
第二单元经常锻炼的女性应该注意他们吃什么。
研究者找到了证据：即使适度的锻炼都会导致铁元素的流失。
他们说，经常锻炼的女性尤其是关于耐力活动，典型的缺铁元素。
为了阻止这样的情况变成一个问题，那类女性增加肉类食物或者服用铁质补充剂以代替铁元素的流失是重要的。
那些不费心去获得大量的铁可能开始觉得虚弱和疲惫。
“如果你能听从建议，在你的饮食中，每天允许有点铁元素，你将可能运转的更好。
”一个饮食专家说，“服用含铁元素的药片的一个缺点是：药片的成分不会很好的被吸收，并且有时会让你恶心。
你试着通过在你的饮食得到更多的富含铁元素的肉类补救这个不足是更合适的。
”有很多方法可以帮助你的身体储存摄入的铁元素。
通过得到大量的维生素C，你的身体能够更好的处理,或使用铁元素。
研究者承认：每个人的身体是不一样的，这个问题对于一些人来说是没那么严肃的。
因为这个对于你来说是否是个问题是不可能判断的，健康专家说：检测你的含铁元素水平是明智的。
即使你不会感觉到，你仍然可能有问题。
《大学英语4 》复习自整理2017年6月20日柏映羽版权所有，请勿翻印第一单元MAN AND NATURE一．TEXTA（P4-7）课文翻译：人在自然界亚历山大•斯伯金1 人类生活在大自然的王国里。
他们时刻被大自然所包围并与之相互影响。
人类呼吸的空气、喝下的水和摄入的食物，无一不令人类时刻感知到大自然的影响。
我们与大自然血肉相连，离开大自然，我们将无法生存。
2 人类不仅生活在大自然之中，同时也在改变着大自然。
人类把自然资源转变为各种文化、社会历史的财富。
人类降服并控制了电，迫使它为人类社会的利益服务。
人类不仅把各种各样的动植物转移到不同的气候环境下，也改变了他所生活环境的地貌和气候，并使动植物因之而发生转变。
3 随着社会的发展，人类对大自然的直接依赖越来越少，而间接的依赖却越来越多。
我们远古的祖先生活在大自然的威胁及破坏力的恐惧之中，他们常常连基本的生活物资都无法获取。
然而，尽管工具不甚完备，他们却能同心协力，顽强工作，并总是有所收获。
在与人类的相互作用中，大自然也发生了改变。
森林被破坏了，耕地面积增加了。
大自然及其威力被看成是和人类敌对的东西。
譬如，森林被认为是野性的和令人恐惧的，因此人类便想方设法使其面积缩小。
这一切都是打着“文明”的旗号进行的，所谓“文明”，就是指人类在那些地方建立了家园，那些地方的土地得以耕耘，那里的森林已被砍伐。
4 然而，随着岁月的流逝，人类越来越关注的是在何处以及如何得到生产所需的不可替代的自然资源的问题。
科学与人类改变大自然的实践活动已经使人类意识到了工业在改变地球的进程中对地质产生的重大影响。
5 目前，人与自然以及自然与社会整体之间过去存在的动态平衡，已呈现崩溃的迹象。
生物圈中所谓可替代资源的问题变得极为严重。
人类和社会的需求，即便是像淡水一样的物质，也变得越来越难以满足。
清除工业废物的问题也变得日益复杂。
6 现代技术的特征是生产和使用日益丰富的人工合成产品。
人们生产成千上万种人工合成材料。
Unit 6"Don't ever mark in a book!" Thousands of teachers, librarians and parents have so advised. But Mortimer Adler disagrees. He thinks so long as you own the book and needn't preserve its physical appearance, marking it properly will grant you the ownership of the book in the true sense of the word and make it a part of yourself.HOW TO MARK A BOOKMortimer J. AdlerYou know you have to read "between the lines" to get the most out of anything. I want to persuade you to do something equally important in the course of your reading. I want to persuade you to "write between the lines." Unless you do, you are not likely to do the most efficient kind of reading. You shouldn't mark up a book which isn't yours. Librarians (or your friends) who lend you books expect you to keep them clean, and you should. If you decide that I am right about the usefulness of marking books, you will have to buy them.There are two ways in which one can own a book. The first is the property right you establish by paying for it, just as you pay for clothes and furniture. But this act of purchase is only the prelude to possession. Full ownership comes only when you have made it a part of yourself, and the best way to make yourself a part of it is by writing in it. An illustration may make the point clear. You buy a beefsteak and transfer it from the butcher's icebox to your own. But you do not own the beefsteak in the most important sense until you consume it and get it into your bloodstream. I am arguing that books, too, must be absorbed in your bloodstream to do you any good.There are three kinds of book owners. The first has all the standard sets and best-sellers -- unread, untouched. (This individual owns wood-pulp and ink, not books.) The second has a great many books -- a few of them read through, most of them dipped into, but all of them as clean and shiny as the day they were bought. (This person would probably like to make books his own, but is restrained by a false respect for their physical appearance.) The third has a few books or many -- every one of them dog-eared and dilapidated, shaken and loosened by continual use, marked and scribbled in from front to back. (This man owns books.)Is it false respect, you may ask, to preserve intact a beautifully printed book, an elegantly bound edition? Of course not. I'd no more scribble all over a first edition of "Paradise Lost" than I'd give my baby a set of crayons and an original Rembrandt! I wouldn't mark up a painting or a statue. Its soul, so to speak, is inseparable from its body. And the beauty of a rare edition or of a richly manufactured volume is like that of painting or a statue. If your respect for magnificent binding or printing gets in the way, buy yourself a cheap edition and pay your respects to the author.Why is marking up a book indispensable to reading? First, it keeps you awake. (And I don't mean merely conscious; I mean wide awake.) In the second place, reading, if it is active, is thinking, and thinking tends to express itself in words, spoken or written. The marked book is usually the thought-through book. Finally, writing helps you remember the thoughts you had,or the thoughts the author expressed. Let me develop these three points.If reading is to accomplish anything more than passing time, it must be active.you can't let your eyes glide across the lines of a book and come up with an understanding of what you have read. Now an ordinary piece of light fiction, like, say, "Gone with the Wind," doesn't require the most active kind of reading. The books you read for pleasure can be read in a state of relaxation, and nothing is lost. But a great book, rich in ideas and beauty, a book that raises and tries to answer great fundamental questions, demands the most active reading of which you are capable. You don't absorb the ideas of John Dewey the way you absorb the crooning of Mr. Vallee. You have to reach for them. That you cannot do while you're asleep. If, when you've finished reading a book, the pages are filled with your notes, you know that you read actively. The most famous active reader of great books I know is President Hutchins, of the University of Chicago. He also has the hardest schedule of business activities of any man I know.He invariably read with pencil, and sometimes, when he picks up a book and pencil in the evening, he finds himself, instead of making intelligent notes, drawing what he calls " caviar factories" on the margins. When that happens, he puts the book down. He knows he's too tired to read, and he's just wasting time.But, you may ask, why is writing necessary? Well, the physical act of writing, with your own hand, brings words and sentences more sharply before your mind and preserves them better in your memory. To set down your reaction to important words and sentences you have read, and the questions they have raised in your mind, is to preserve those reactions and sharpen those questions. You can pick up the book the following week or year, and there are all your points of agreement, disagreement, doubt and inquiry. It's like resuming an interrupted conversation with the advantage of being able to pick up where you left off.And that is exactly what reading a book should be: a conversation between you and the author. Presumably he knows more about the subject than you do; naturally you'll have the proper humility as you approach him. But don't let anybody tell you that a reader is supposed to be solely on the receiving end. Understanding is a two-way operation; learning doesn't consist in being an empty receptacle. The learner has to question himself and question the teacher. He even has to argue with the teacher, once he understands what the teacher is saying. And marking a book is literally an expression of your differences, or agreements of opinion, with the author.There are all kinds of devices for marking a book intelligently and fruitfully. Here's the wayI do it:1. Underlining: of major points, of important or forceful statements.2. Vertical lines at the margin: to emphasize a statement already underlined.3. Star, asterisk, or other doo-dad at the margin: to be used sparingly, to emphasize the ten or twenty most important statements in the book.4. Numbers in the margin: to indicate the sequence of points the author makes in developing a single argument.5. Number of other pages in the margin: to indicate where else in the book the author made points relevant to the point marked; to tie up the ideas in a book, which, though they may be separated by many pages, belong together.6. Circling of key words or phrases.7. Writing in the margin, or at the top or bottom of the page, for the sake of: recording questions (and perhaps answers) which a passage raise in your mind; reducing a complicated discussion to a simple statement; recording the sequence of major points right through the book. I use the end-papers at the back of the book to make a personal index of the author's points in the order of their appearance.The front end-papers are, to me, the most important. Some people reserve them for a fancy bookplate, I reserve them for fancy thinking. After I have finished reading the book and making my personal index on the back end-papers, I turn to the front and try to outline the book, not page by page, or point by point (I've already done that at the back), but as an integrated structure, with a basic unity and an order of parts. This outline is, to me, the measure of my understanding of the work.。
