　　Most people would like to be popular with others，but not everyone can achieve this goal. What is the secret to popularity? In fact，it is very simple. The first step is to improve our appearance. We should always make sure that we stay in good shape and dress well. When we are healthy and well-groomed，we will not only look better but also feel better. In addition，we should smile and appear friendly. After all，our facial expression is an important part of our appearance. If we can do this，people will be attracted to our good looks and impressed by our confidence.

　　Another important step is developing more consideration for others. We should always put others first and place their interests before our own. Its also important to be good listeners; in this way people will feel comfortable enough to confide in us. However，no matter what we do，we must not gossip. Above all，we must remember to be ourselves，not phonies. Only by being sincere and respectful of others can we earn their respect. If we can do all of the above，I am sure popularity will come our way.

　　如何才能受人欢迎

　　大部分的人都想受人欢迎，但是并非每个人都能达到目标。受欢迎的秘诀何在?事实上是很简单的。步骤一，先改善我们的外表。我们得确保自己很健康，并且穿着体面。当我们既健康又穿戴整齐时，不仅看起来更有精神，自己也会觉得好多了。此外，我们要保持微笑并表现得很友善。毕竟，脸部表情是外观很重要的一环。如果我们能做到这一点，别人会被我们的美好外表所吸引，并对我们的自信印象深刻。

　　另一个重要步骤，就是培养对别人的体贴。永远以他人为重，并把别人的利益放在自己的利益之前。当个好听众也是很重要的`;如此一来，别人才能很自在地对我们吐露心事。然而，不管我们做什么事，绝对不要说闲言闲语。最重要的是，要做自己，不要当虚伪的人。只有对人真诚又尊重时，才能赢得他人的尊敬。如果我们能做到以上几点，我相信受人欢迎是指日可待的事。

　　My Attitude towards to Marks我的分数观

　　For our students，marks is above everything. Teachers will judge us from our marks. With marks we can be enrolled into junior middle schools. With marks，we can be enrolled into senior middle schools. With marks we can be enrolled into college. With marks we can be enrolled into postgraduate and doctrine studies. Still with marks we can be graded and be allowed to go abroad for further studies. Our parents will be strict with us with the marks. Our society judge us from marks. However，sometimes we students compare one another with marks directly. We are completely controlled by marks. We like them and we feel sorry for them. But what attitude towards our marks should we take? Truly，marks functions cannot be underestimated. In terms of test in our study，marks are fair and real. That is the reason why we say Everyone is equal before marks.

　　However，I think marks are the sole standard to judge the success or failure of students in exams. Sometimes，marks more than ten or less than one or two in our exams comparing with others mean not everything. The success or failure in exams will be influenced by experience on the spot and the examinee’s health etc. Once in a while one cannot fail in exams. Success or failure is common sense for military. I think everyone is familiar with the famous saying. Don’t you think such will be the case with our study? In exams，one cannot be never-defeated general . Even though one will be very good in everyday study，he cannot succeed in every exam sometimes. We can get proof from the fact that the very best one we call Number One Scholar in the entrance exams for college and ordinary middle school and specialized secondary school over the years is not eminent above all others nor top student in every study.

　　As a matter of fact，high marks and ability are not unified. Some time

　　ago，a new phrase high marks but poor competence came into being. Once I happened to meet such a teacher as this .It is said that the teacher just graduated from a far-famed key university. But his teaching result is much less than that of the one who just graduated from a not-well-renowned college. When lecturing，the teacher only repeated what the text-books says，which was very dull so the his students’ interest in learning was not aroused. His teaching was short of unity of teaching and learning. At present there is a fact that we know a few brilliant and top college graduates are not qualified for their posts. The reason for it may be lack of the ability to combine knowledge learnt from books with pragmatics in their work. Students of this kind will be successful in every exam but they will be able to use freely their knowledge in their posts. Don’t you think it waste training such persons for the country?

　　To sum up from the above，I can say marks are not absolutely authoritative for some. If we neglect training and developing the students’ ability and competence and if we only seek for the high marks，we will be absolutely wrong. We should take an objective attitude towards the marks. Neither should we neglect them nor should we overvalue them like a God.

　　分数，对于我们学生来说，是至关重要的了。老师要用分数来衡量我们—上初中，要分数;上高中，要分数;上大学要分数，考研究生、博士要分数，出国、评职称还是要分数。家长要用分数来要求我们;社会用分数来衡量我们。

　　而我们自己也常常用分数在相互直接做着攀比。我们完全为分数所左右了，我们为它欢喜，我们为它丧气。那么，我们应该怎样对待分数呢?

　　的确，分数有它不可低估的作用。从检验学习的角度上来说，它具有一定的公平性和真实性，“分数面前人人平等”，讲的就是这个道理。然而，分数并不是估量一个学生成败得失的惟一标准。考试成绩偶尔低了一两分乃至十来分，并不一定说明什么问题。考试的成败有时也会受到诸如临场经验、健康状况等方面的影响。“胜败乃是兵家常事”这句话大概不会有人不知道，而我们在学习上又何尝不如此?在考试上很少有“常胜之师”，即使平时成绩再好的同学，也难免会有偶尔的.失误。历届中考、高考“状元”并非就是平时出类拔萃的优等生的事实，便是明证。

　　事实上，“高分”与“能力”往往是不统一的。前段时间，社会上出现了一个新词：“高分低能”。笔者就曾经碰见这样一位教师，据说他毕业于某赫赫有名的重点大学，但从教学效果上讲，却远远逊色于一些非高等学府毕业的老师。其授课只是照本宣读而已，枯燥乏味，缺乏一种教与学之间的协调功能。根本不能引起听课同学的兴趣，目前不少大中专院校的高材生毕业后不能胜任他们的工作，原因就在于缺少将书本中的知识运用到实际工作中去的能力。这种人，尽管在学校中每每能考出高分，可无法在工作岗位上灵活白如地运用自己所学到的

　　知识。国家培养出这样的“人材”，不也是一种浪费吗?

　　由此可见，分数并不如有些人想象得那么绝对和，忽视了对各方面才能的培养，只一味追求高分，是不行的。因此，我们应该客观地去看待分数，既不应过分轻视它，也没有必要把它看得过于神圣。

　　In Other Ways

　　其他开场方式欣赏

　　Today I come to Oslo as a trustee，inspired and with renewed dedication to humanity; I accept this prize on behalf of all men who loved peace and brotherhood. I say I come as a trustee，for in the depths of my heart I am aware that this prize is much more than an honor to me personally.

　　今天，我以受托人的身份来到奥斯陆，心情激动，充满了献身人类的新勇气。我代表所有热爱和平与兄弟情谊的人们接受这个奖。我之所以以受托人的身份来到这里，是因为，在我的内心深处，我意识到这个奖决不仅仅是我个人的荣誉。

　　The road of history is not level and smooth all along. Sometimes the path will come to a dangerous and difficult place.

　　It is only with the valiant and gallant spirit of the travelers that it can be passed through.

　　The vast and mighty Yangtzi River，when it comes to an endless，broad plain，will flow ten thousand miles in a rapid current. But as it reaches a narrow valley with high ranges of mountains，cliffs and precipices on both sides，which look dangerously steep，the river has to force its way through them in a winding，tortuous course. The same is the case with the developing course of a nations history.

　　The history of human race is like going on a journey. Some of the places the traveler passes through are smooth and level pianos，and others are dangerous and rugged paths. The experienced travelers，when they moved on to a broad，level road，will naturally walk along with a light heart，but while they are passing through a rugged place they will all the more be seized with curiosity，and in such an extremely fantastic and magnificent realm，will all the more feel a sort of pleasure in an adventure.

　　历史的道路，不总是平坦的，有时会变得艰难险阻。这只能靠英勇无畏的`精神才能够冲过去。

　　一条浩浩荡荡的长江大河，有时流到很宽阔的境界，一望无际，一泻千里。有时流到很逼狭的境界，两岸丛山叠岭，绝壁断崖，江河流于其间，曲折迂回，极为险峻。民族生命的进展，其历程亦复如是。

　　人类在历的生活正如旅行一样。旅途上的征人所经过的地方有时是坦荡平原，有时是崎岖险路。老于旅途的人，走到平坦的地方固是高高兴兴地向前走，走到崎岖的境界，愈是奇趣横生，觉得在此奇艳壮绝的境界，愈能感得一种冒险的美趣。

　　dumpling is a traditional chinese food. On the lunar new year s day most families make a lot of delicious dumplings. To make them follow this easy process.

　　饺子是中国的传统食物。在农历新年，大多数家庭都会包很多美味的饺子。要包成饺子，遵循以下那容易的步骤。

　　The first step is to mix the flour with water. when the dough is ready we can begin to make dumpling wrappers. we use a rolling pole to roll the dough into small thin and round pieces so that they will be easy to cook. when the wrappers are done it s time to prepare the filling. Usually we use meat such as beef or mutton and some vegetables such as cabbage or carrots for filling.You may actually choose whatever you like to put into it. we must chop those things into small pieces.Then put some salt oil and other condiments into it and stir it evenly. When all these preparations are done we can start making dumplings. First put a spoonful of filling in the center of the wrapper. Then stick the two opposite sides together and then the rest. Don t just cover the filling with the wrappers. The best shape of dumplings is that of a ship because when they are boiling in the pan they look like ships sailing in the sea. The smell can make your mouth water.

　　x步就是把面粉和水和在一起。和好面之后，我们可以开始擀皮。我们使用一个滚动杆，把它揉成又薄又小的圆形面皮，这样会比较容易煮。皮弄完后，就是弄馅的时候了。通常我们用肉(比如牛肉和羊肉)还有蔬菜(比如白菜和胡萝卜)作馅。你可能选择任何你喜欢的馅包进去。我们必须把这些东西剁小。然后放上盐，油和其他调料搅拌它均匀。当所有这些准备工作都完成了我们就可以开始包饺子了。首先放一勺馅在皮的中心。然后把两个相反的两边粘在一起，然后就是其他的'了。不只是只是把馅包在皮里面。饺子x好看的形状是像一艘船，因为当它们在锅里煮时，他们看起来就像是大海里的船只。它们的香味会让你流口水。

　　A Chief Executive officer is not necessarily someone who has had a lot offormal training.So, I doubt moreschooling would help you climb up that ladder ofsuccess.

　　Maybe you should try and change your work habits or character. You

　　cannotjust sit around in an organization waiting for people to promote you. You haveto let people know you are ambitious and waiting for biggerand more rewardingchallenges. You should tell your supervisor or boss that you want to be promotedand rise up that management ladder. A good manager will accept, even respect thefact that you wish for career development. If this is not the case, you shouldfind a new job or new company that will allow you to grow.

　　You must start out small. Hoping that one day you will suddenly

　　becomedirector of a company is doubtful. Getting ready for a slow ascent is morelikely. Accept it, and commit yourself, realizing that it may be alongclimb.

　　You will need some skills to propel you up that ladder of success.You mustbe competent, that is you need to develop skills in many areas, such asmarketing, human resources, public relations and finances.

　　You must also be a good people person, always cultivating relationshipswith the people around you.Having “guanxi” is a necessary characteristic of anysuccessful CEO.

　　公司的首席执行官未必都是经过许多正规培训的人。所以，我认为接受更多的学校教育未必就能促使你在成功的阶梯上步步高升。

　　也许，你应该试着改变工作习惯或性格。不能仅仅在一个单位里坐等别人来提升你。必须让人们知道你胸怀大志，正在等待更大的、回报更多的挑战。应该告诉你的上司或老板：你想得到提拔，登上管理者的阶层。一位好经理将会理解，甚重你发展~业的愿望。假如情况不是这样的话，你就应该另谋{就，以使自己得到发展。

　　必须从小处开始做起。幻想着有一天突然当上某公司的领导是不太现实的.。作好准备慢慢地升迁，可能性更大。接受现实，全力以赴，要意识到这可能是一种漫长的攀登。

　　你需要掌握一些促使自己往上爬升的技能。你必须具备胜任工作的各种能力。换句话说，你必须具备诸如市场营销、人力资源、公关和财务等方面的技能。

　　你也必须要有良好的人缘，营造与周围的人黻洽的关系，好的"关系"是任何一位成功的首席执行官必备的要素。

　　Hello, everyone. It is a great honor for me to be here to express my feelings.

　　My friends, it is time for us to say goodbye. However, I will never forget the golden days of junior high school. They are forever locked in my memories! In the past three years, I am grateful that I could study with you.

　　First of all, I’d like to thank all my teachers. It’s you that let me konw how to be a good person. From you, I know that as a good student, we should not only study hard, but also mean well and help each other. Then, I’d like show my appreciation to all my friends. I am grateful that I could study with you. Being together with you, I can totally be myself. I do not need to hide anything from you. When I am sad, you are always on my side to cheer me up.

　　We will soon become senior high school students. We must go forward, to a different world, we are no longer the children, who only want to play fun with each other. We grow up from now on! It is a long journey, but let us begin!

　　你好，每个人。我很荣幸在这里表达自己的感情。

　　我的朋友们，这是我们说再见的时间。然而，我将永远不会忘记初中黄金时代。他们永远锁在我的记忆中！在过去的三年中，我很感激我能和你们一起学习。

　　首先，我想感谢我所有的老师。是你们，让我知道如何成为一个好人。从你们那，我知道作为一个好学生，我们不仅应该努力学习，也要互相帮助。然后，我想对我所有的`朋友们表示衷心的感谢。我很感激我能和你一起学习。和你在一起，我完全可以做我自己。我不需要你隐瞒任何事情。当我伤心的时候，你总是在我身边使我振作。

　　我们将很快成为高中生。我们必须前进，在不同的世界里，我们不再是孩子，只想和对方快乐地玩的孩子。我们长大了，从现在开始！这是一个漫长的旅程，但让我们开始吧！

　　世界是我们的，未来是我们的

　　Someone said “we are reading the first verse of the first chapter of a book，whose pages are infinite”. I don’t know who wrote these words，but I’ve always liked them as a reminder that the future can be anything we want it to be. We are all in the position of the farmers. If we plant a good seed，we reap a good harvest. If we plant nothing at all，we harvest nothing at all.

　　一些人说“我们正在读一本无穷的书中的第一章的第一节.”我不知道谁写了这些话，但是我一直很喜欢它，因为它提醒了我，我们能够创造我们想要的未来.

　　We are young. “How to spend the youth？” It is a meaningful question. To answer it，first I have to ask “what do you understand by the word youth？” Youth is not a time of life，it’s a state of mind. It’s not a matter of rosy cheeks，red lips or supple knees. It’s the matter of the will. It’s the freshness of the deep spring of life.

　　我们都是农夫.如果我们播下好的种子，我们将会丰收.如果我们的种子很差，有很多草籽，收割的将是无用的庄稼.如果我们什么也不播种，什么收获也没有.

　　Youth means a temperamental predominance of courage over timidity of the appetite，for adventure over the love of ease. This often exists in a man of 60 more than a boy of 20 . Nobody grows old merely by a number of years . We grow old by deserting our ideals. Years wrinkle the skin，but to give up enthusiasm wrinkles the soul . Worry，fear，self –distrust bows the heart and turns the spirit back to dust .

　　我们是年轻的“怎样度过青春？”这是个有意义的问题.为了去回答它，我首先要问“从‘青春’这个词中你能理解到什么？”青春不是人生的一个时期，而是精神的一种状态.青春不是桃面、丹唇、柔膝，而是深沉的意志，.青春是生命的深泉在涌流.

　　Whether 60 of 16，there is in every human being ‘s heart the lure of wonders，the unfailing childlike appetite of what’s next and the joy of the game of living . In the center of your heart and my heart there’s a wireless station：so long as it receives messages of beauty，hope，cheer，courage and power from men and from the infinite，so long as you are young .

　　A poet said “To see a world in a grain of sand，and a heaven in a wild flower，hold infinity in the palm of your hand，and eternity in an hour. Several days ago，I had a chance to listen to a lecture. I learnt a lot there. I’d like to share it with all of you. Let’s show our right palms. We can see three lines that show how our love.career and life is. I have a short line of life. What about yours？I wondered whether we could see our future in this way. Well，let’s make a fist. Where is our future？Where is our love，career，and life？Tell me.Yeah，it is in our hands. It is held in ourselves.

　　一位诗人说“从一粒沙看世界，从一朵花看天堂，把无限放在你的手掌，永恒在一刹那里收藏”.几天前，我有了一个听讲座的机会，从中我学到了很多东西.现在，我想把这些与大家共享.让我们伸出右手，我们可以看到手掌中的展示我们的爱，事业和生活的三条线.我在生活方面这条线很短，那你们的呢？我想知道我们是否可以用这种办法去看我们的.未来.好的，让我们一起握拳.我们的未来在哪儿？我们的爱、事业和生活在哪儿？告诉我！是的，它们就在我们的手中.它们被我们自己掌握着.

　　We all want the future to be better than the past. But the future can go better itself. Don’t cry because it is over，smile because it happened. From the past，we’ve learnt that the life is tough，but we are tougher. We’ve learnt that we can’t choose how we feel，but we can choose what about it. Failure doesn’t mean you don’t have it，it does mean you should do it in a different way. Failure doesn’t mean you should give up，it does mean you must try harder.

　　我们所有人都希望未来能比过去更美好，但是未来能自己变得更好.不要因为结束而哭泣，微笑吧，为你的曾经拥有.从过去来看，生活是艰苦的，但我们是更坚强.我们知道我们不能选择感觉，但是我们能选择和它相关的东西.失败并不意味着你不拥有成功，它只意味着你应该用另一种方式去做这件事.失败并不意味着你应该放弃，只意味着你应该更加努力.

　　As what I said at the beginning，“we are reading the first verse of the first chapter of a book，whose pages are infinite”. The past has gone. Nothing we do will change it. But the future is in front of us. Believe that what we give to the world，the world will give to us. And from today on，let’s be the owners of ourselves，and speak out “We are the world，we are the future.”

　　正如我在前面所说的“我们正在读一本无穷的书中的第一章的第一节.”过去的已经过去，无论我们无力改变，但是未来却在我们前方.相信“我们给了世界什么，世界也将给我们”.并且从今天起，让我们一起做我们自己的主人，一起大声说出“世界是我们的，未来是我们的”

　　with the development of science and technology, change has penetrated into every aspect of our daily life. to illustrate that, id like to make a comparison of these two seemingly insignificant things: milkman and mailman, whose differences indicate our changing way of living with the times.

　　home milk delivery has almost gone extinct in china now, also gone with it are the milkmen, who once delivered bottled fresh milk door-to-door. on the other hand, mailmans business or the courier service has thrived as online shopping gains popularity. however, in retrospect, i find something has been lost in this transition, something shakespeare called as “the milk of human kindness”。

　　when i was a kid, milk wasnt for sale everywhere. for the families who need it, they depended on the milkmen to take it from the local dairy farms to their houses. in our neighborhood, there was such a milkman, whose arrival was much anticipated by the children and always brought us laughter and joy. he knew the name of every kid and could easily see through our tricks. if we didnt behave, he would side with our parents and threaten to rob us of the nutritious drink. the entire neighborhood was acquainted with him; saw him as a member of the community just like the many residents or street vendors. there was a bond between all of us for it was not only the commodities that been transacted, but also a sense of caring and dependability. and that small box fixed onto our door, other than being a drop-off point for milk; it was a communication junction between the people as we took the initiative to reach out to others.

　　fast forward to today, milk is ubiquitous with no dedicated delivery system. but the convenience level of our live has gone up a notch. almost everything is for sale online, which spares us all the travelling and talking. with a few ready clicks, shopping is done. the rest is left for those speed delivery companies. usually its a grumpy mailman, who reaches us through cell phone, urging everyone to pick up their parcels as soon as possible. and the minute the receipt is signed, we rush back to unpack while the courier dashes to the next destination. there is barely a conversation carried out, nor do we feel the need to talk to such a stranger, who changes from time to time frequently. it seems that people are always in a hurry now, though we have more conveniences, still we run short of time to stop and stare, to speak and share.

　　call me an old-timer, but i think the personal touch represented by the milkman is what has been missing in the modern society. william wordsworth once wrote that “getting and spending, we lay waste our powers.” modern technology may have multiplied our possessions or gave us more conveniences, but we run the risk of reducing our values if we lay waste our power of interpersonal relationships.

　　随着科学技术的发展，变化已经渗透到我们日常生活的方方面面。要说明的是，我想让这两个看似不起眼的东西比较：牛奶，邮递员，其差异表明我们与时代生活方式的改变。

　　家里的牛奶几乎已经灭绝，现在在中国，它也消失了的送奶工，曾送瓶装草原鲜奶送货上门。另一方面，邮递员的业务或快递服务的蓬勃发展，网上购物的普及。然而，回想起来，我发现在这一转变中，有了一些东西，莎士比亚称之为“人类之奶”。

　　当我还是个孩子的时候，牛奶不是到处都卖。对于那些有需要的家庭来说，他们只能依靠送奶工把它从当地的乳品农场房子。在我们的附近，有这样一个送牛奶的人，他们的到来，是孩子们期待已久的，总是给我们带来笑声和欢乐。他知道每一个孩子的名字，可以很容易地通过我们的把戏。如果我们不守规矩，他会和我们的父母一起威胁要抢我们的营养饮料。整个社区都与他熟识，他认为他是社会上的一员，就像许多居民和街头小贩一样。有一个我们之间的.结合不仅是被交易的商品，也有关心和信任。和那个小盒子固定在我们的门，而不是一个下降点牛奶，它是一个沟通的人之间的交界处，我们采取了主动接触其他人。

　　快速前进到今天，牛奶是无处不在的没有专门的交付系统。但是我们的生活便利程度已经上升了一个缺口。几乎所有的东西都在网上出售，这使我们所有的旅行和谈话都有了。用几点准备，购物就完成了。其余的则是留给那些快速交货的公司。它通常是一个脾气暴躁的邮递员，他通过手机与我们联系，希望每个人都拿起他们的包裹尽快。和一分钟的收据签字，我们赶回来打开而快递冲到下一个目的地。我们几乎没有进行一次谈话，也不觉得有必要对这样一个陌生人说话，他经常改变时间。似乎人们总是在匆匆忙忙的现在，虽然我们有更多的方便，但我们却没有时间停下来盯着，说，分享。

　　叫我老古董，但我认为送奶工为代表的个人风格是什么一直在现代社会中失踪。华兹华斯威廉曾写道：“获取和消费，我们浪费我们的权力。”现代科技可能会增加我们的财产，或者给我们更多的便利，但是我们冒风险的减少我们的价值，如果我们浪费我们的人际关系的力量。

　　The operational [??p??rei??n?l] amplifier [??mpl??fa??] is an extremely efficient and versatile [?v?:s?tail] 通用device. Its applications span the broad electronic industry filling requirements for signal conditioning, special transfer functions, analog [??n??l?:g] 模拟instrumentation, analog computation, and special systems design. The analog assets [??set ] of simplicity [sim?plisiti] and precision characterize circuits

　　[?s?:kit]utilizing [?ju:tilaiz] operational amplifiers.

　　运算放大器是一个非常有效和通用设备。它的应用范围广泛的电子工业，信号调理，专项转移功能，模拟仪表，模拟计算，及特殊系统设计的灌装要求。简单性和精确度是使用运算放大器的模拟电路特点

　　The Feedback Technique

　　The precision and flexibility of the operational amplifier is a direct result of the use of negative feedback. Generally speaking, amplifiers employing feedback will have superior operating characteristics at a sacrifice [?s?krifais]of gain.

　　在运算放大器的精度和灵活性是利用负反馈的直接结果。一般来说，采用反馈的放大器有卓越的经营特点，在牺牲增益的代价下。

　　With enough feedback, the closed loop amplifier characteristics become a function of the feedback elements. In the typical feedback circuit, figure 1, the feedback elements are two resistors. The precision of the “closed loop” gain is set by the ratio [?rei?i?u] 比率of the two resistors and is practically independent of the “open loop” amplifier. Thus, amplification to almost any degree of precision can be achieved with ease.

　　有了足够的反馈，闭环放大器的特点成为一个功能的反馈元件。在典型的反馈电路中，图1中，反馈元件是两个电阻器。的精度的“闭环”的增益设置的两个电阻的比率实际上是独立的“开环”放大器。因此，放大到几乎任何的精确度，可以容易地实现。

　　Notation符号

　　?= Symbol (a) is a buffer [?b?f?] 缓冲器 op工作 amp放大器

　　?= Symbol (b) is a differential input, single ended output op amp. This symbol represents the most common types of op amps, including voltage feedback, and current feedback. It is often times pictured with the non-inverting input at the top and the inverting input at the bottom.

　　?= Symbol (c) is a differential input, differential output op amp. The outputs can be thought of as “inverting” [in?v?:t] 反转and “non-inverting”, and are shown across from

　　the opposite [??p?zit]相反 polarity [p???l?r?ti] 极性 input for easy completion

　　[k?m?pli:??n] 完成of feedback loops on schematics [ski:?m?t?k].

　　符号（a）是一个缓冲器的运算放大器

　　?=符号（b）是一个差分输入，单端输出的运算放大器。这个符号代表最常见的类型，包括电压反馈和电流反馈运算放大器。它通常是在顶部和在底部的倒相输入端与非反相输入描绘的时间。

　　?=符号（C）是差分输入，差分输出运算放大器。输出可以被认为是“反转”和“非反相”，并示出从相反的极性的输入对面容易完成的`反馈回路原理图

　　Power Connections电源连接

　　Power is supplied to each of these units at connections as shown in figure 4. Such a connection is implied in all operational amplifier circuits. The dual [?dju:?l]两部分

　　supply presents the same absolute value of voltage to ground from either side, while the center connection ultimately [?ltim?tli]最宗defines the common line and ground potential. The exceptions to this are AC amplifier circuits that may use a single power supply. This is accomplished by creating a floating [?fl??t??] AC ground with DC blocking capacitors. In such circuits, a source of “half-supply” creates a “virtual ground” exactly half way between the positive supply and ground potentials.

　　电源供给到这些单元中的每一个，如在图4中所示的连接。这样的连接是隐含在所有的运算放大器电路。双电源呈现相同的绝对电压值从任一侧接地，而中心连接最终定义的公共线和接地电位。例外情况是可以使用单个电源的AC放大器电路。这是通过创建一个浮动的AC地面的隔直流电容器。在这种电路中，“半电源”的来源创建一个“虚拟地”正好有一半之间的正电源和接地电位的方法。

　　Electrical Circuit Models电气电路模型

　　The simplified models of the differential [?d?f??ren??l] 差分input operational amplifiers are shown in figures 6 and 7.

　　在图6和图7中示出的差分输入运算放大器的简化模型。

　　As indicated in figure 6, the operational amplifier can be represented by an ideal voltage source whose value depends on the input voltage appearing across the inverting and non-inverting inputs plus the effects of finite [?fainait] 有限input and output impedances [im?pi:d?ns]阻抗. The value, A, is known as the open loop (without feedback) gain of the operational amplifier.

　　正如在图6中所示，运算放大器可以表示为一个理想电压源，其值取决于对输入电压的两端出现的反相和非反相输入端加上有限的输入和输出阻抗的影响。值，A，是被称为在运算放大器的开环增益（没有反馈）。

　　The simplified model of the differential output operational amplifier (figure 7) is an accurate [??kjurit] approximation [??pr?ks??me???n] 近似值only under special conditions of feedback (see “Balanced Amplifier” later in this handbook). Figure 6 represents the model of the differential output type when it is used as a single ended output device; the inverting output simply being ignored.

　　简化模型的差分输出运算放大器（图7）是一个准确近似，仅在特殊条件下的反馈（见“平衡放大器”，在本手册后面）。图6表示的差分输出的模型类型时，它被用作一个单端输出的移动设备简单地被忽略的反相输出。

　　The Ideal Operational Amplifier理想运算放大器

　　In order to introduce operational amplifier circuitry, we will use an ideal model of the operational amplifier to simplify the mathematics [?m?θi?m?tiks] involved in deriving gain expressions, etc., for the circuits presented. With this understanding as a basis, it will be convenient to describe the properties of the real devices themselves in later sections, and finally to investigate circuits utilizing practical operational amplifiers. 为了介绍运算放大器电路中，我们将使用一个理想的模型简化中获得的电路增益表达式等，所涉及的数学运算放大器的。有了这样的认识，以此为基础，可以方便的真实设备本身在后面的章节中描述的属性，最后调查利用实际的运算放大器电路。

　　To begin the presentation of operational amplifier circuitry [?s?:kitri], then, it is necessary first of all to define the properties of a mythical “perfect” operational amplifier. The model of an ideal operational amplifier is shown in figure 9.

　　首先介绍运算放大器电路，那么，它是必要的，首先要定义一个神话般的“完美”的运算放大器的性能。理想的运算放大器的模型是在图9中所示。

　　Defining the Ideal Operational Amplifier

　　?= Gain: The primary function of an amplifier is to amplify, so the more gain the better. It can always be reduced with external circuitry, so we assume gain to be infinite

　　[?infinit]无限.

　　增益：放大器的主要功能是放大的，所以更多的获得更好。它总是可以减少与外部电路，所以我们假设增益是无限

　　?= Input Impedance: Input impedance is assumed to be infinite. This is so the driving source won’t be affected by power being drawn by the ideal operational amplifier. 输入阻抗：输入阻抗被认为是无限的。这是这样的驱动源将不会受到影响被绘制了理想的运算放大器的功率。

　　?= Output Impedance: The output impedance of the ideal operational amplifier is assumed to be zero. It then can supply as much current as necessary to the load being driven.

　　输出阻抗：理想的运算放大器的输出阻抗被假定为零。然后，它可以提供尽可能多的电流所必需的被驱动的负载。

　　?= Response Time: The output must occur at the same time as the inverting input so the response time is assumed to be zero. Phase shift will be 180?. Frequency response will be flat and bandwidth infinite because AC will be simply a rapidly varying DC level to the ideal amplifier.

　　响应时间：输出必须在相同的时间发生的反相输入端，这样的响应时间被假定为零。相移为180?。频率响应是平的，无限的，因为交流会只是一个快速变化的DC电平的理想放大器的带宽。

　　?= Offset: The amplifier output will be zero when a zero signal appears between the inverting and non-inverting inputs.

　　偏移量：当一个零信号之间出现的反相和非反相输入端，放大器的输出将为零。

　　CIRCUITS AND ANALYSES USING THE IDEAL OPERATIONAL AMPLIFIER用理想运算放大器的电路及分析

　　The Desirability of Feedback是可取的反馈

　　Consider the open loop amplifier used in the circuit of figure 10. Note that no current flows from the source into the inverting input - the summing point restraint derived in the previous section - hence, there is no voltage drop across RS and ES appears across the amplifier input. When ES is zero, the output is zero. If ES takes on any non-zero value, the output voltage increases to saturation [?s?t???re???n] 饱和, and the amplifier acts as a switch.

　　考虑图10的电路中使用的开环放大器。请注意，从源代码编译成的反相输入端 - 来自上一节中的求和点约束 - 因此没有电流流过，有没有RS两端的电压降和ES出现整个放大器的输入。当ES是零，其输出为零。如果ES承担任何非零的值，输出电压增大到饱和，该放大器作为一个开关。

　　The open loop amplifier is not practical - once an op amp is pushed to saturation, its behavior is unpredictable. Recovery time from saturation is not specified for op amps (except voltage limiting types). It may not recover at all; the output may latch up. The output structure of some op amps, particularly rail-to-rail models, may draw a lot of current as the output stage attempts to drive to one or the other rail. For more details on op amps in open loop operation, consult reference 1.

　　开环放大器是不实际的 - 一旦一个运算放大器推到饱和，它的行为是不可预测的。未指定恢复时间从饱和运算放大器的（除了电压限制类型）。它可能无法收回;输出锁存。作为输出级试图把车开到一个或其他铁路的一些运算放大器，尤其是轨到轨车型，可能会吸引大量的电流输出结构。对于运算放大器开环运行的详细信息，请参阅参考文献1。

　　feet, the carriers of life

　　good morning, ladies and gentlemen.

　　i would like to tell you about an unusual assignment. i was surprised and amused when our teacher told us our homework was to wash our feet carefully .

　　yeah, washing the feet is such a common daily activity that i’ve never paid much attention to it. my feet had been cooperating and helping each other, nearly always managing to get washed, while i was enjoying my readings. but that night, while i gently touched my feet in the hot water, i realized how nice and cozy bathing my feet could be.

　　deep in my mind, the hands always seemed superior to the feet. people use all sorts of things from soap to moisture cream to protect their hands. the feet become, kind of, neglected, since the feet spend all day long with the ground and dirt, and quite inevitably, get really smelly.

　　as i slowly soaped and rinsed my feet, i was beginning to

　　understand why my teacher launched such a mission. she wanted us to realize that the feet were more helpful than we had ever imagined.

　　surely, the hands are important. however it’s the feet that carry your whole body weight, and everything about your life.

　　the feet carry you, as well as your hopes and dreams, and walk steadily upon the most solid ground, moving forward step by step,

　　upon mountains and down valleys, over the smooth as well as the rough, through the bitterness as well as the joy.

　　as i was washing my feet, i let my mind wander. i felt as if i was on a vast desert. looking around, i saw millions of footprints, large and small, deep and shallow, being the marks of existence, and the traces of life. and there i was, using my own feet, making my own path, towards the oasis of life……

　　thank you.

　　脚，生命的载体

　　女士们，先生们，上午好!

　　我想告诉大家一份不寻常的家庭作业，老师布置我们当晚回家认真给自己洗一遍脚，听到后，我感到惊奇而有趣。

　　是啊，脚，我每晚必洗，但从未重视过。洗脚时，我津津有味地看着书，任双脚摩挲，互帮互助。但今晚，当我的双手触摸到自己的双脚时，是多么的舒服、惬意啊!

　　心中，总是觉得手比脚高贵，人们用香皂洗手，并抹上护手霜，百般呵护;而脚踩在地上，即使有鞋袜，也总被认为是与灰土打交道的粗笨一族，并有不可避免的异味，脚，似乎成了身体中被忽视的部分。

　　我仔细地洗着脚，渐渐地，我明白了老师的用意：她布置这个特殊的任务，是为了让我们认识到脚，其实比我们想象的更伟大。

　　无可争议，手固然重要。可脚却承担着你生命的全部重量。

　　脚，负着你，你沉甸甸的`希望和梦想，踩着踏实的大地，一步一步地前进，走上了高山也走下了峡谷，走过了平坦也走过了崎岖，走过了苦难也走过了幸福。

　　我在洗脚，手脚依偎，恍惚间，我仿佛置身于广袤的大漠中。环视四周，一串串大大小小深深浅浅的脚印，这是存在的证明，生命的印迹。而我用自己的双脚，开辟着自己的道路，向生命的绿洲前进……

　　谢谢!

　　Good morning everyone,Today, I would like to talk about youth, a period of our life that we often take for granted. Youth is a time when we are filled with boundless energy and possibilities, an age when we can dream big and work hard to make those dreams come true. As teenagers, we may feel that our youth is eternal, and that we have all the time in the world to chase our goals. But the truth is, our youth is fleeting, and it’s up to us to make the most of it.

　　During our teenage years, we are presented with countless opportunities to learn, grow, and achieve. Whether it’s through education, sports, or extracurricular activities, we have the chance to develop our skills, discover our passions, and build a solid foundation for our future. However, we must also be aware that our decisions and actions during our youth can have lasting consequences. Therefore, we should make wise choices, cultivate healthy habits, and surround ourselves with positive influences.

　　Moreover, youth is not just a time for self-improvement, but also a time for contribution. As young people, we are capable of making a difference in the world, no matter how small or big our contributions may be. By volunteering, advocating for important causes, or simply being a good friend to those in need, we can positively impact the lives of others and create a better future for ourselves and those around us.

　　In conclusion, youth is a precious gift that we should cherish and make the most of. Let us seize this time with enthusiasm, determination, and compassion. Let us also remember that our youth will not last forever, and that the decisions we make and the actions we take today will shape the person we become tomorrow.

　　Thank you.

　　大家早上好，今天我想谈谈青春，这是我们经常认为理所当然的一段人生。青春充满了无限的能量和可能性，是一个我们可以梦想远大，努力实现这些梦想的年龄。作为青少年，我们可能会觉得青春永恒，认为我们有无限的时间去追逐我们的目标。但事实是，我们的青春是短暂的，我们需要充分利用这段时间。

　　在我们的少年时期，我们有无数的机会来学习、成长和实现。通过教育、运动或课外活动，我们有机会发展自己的技能，发现自己的激情，并为自己的未来打下坚实的基础。然而，我们也必须意识到，在我们的`青春期间的决定和行动可能会产生长远的影响。因此，我们应该做出明智的选择，培养健康的习惯，并周围自己正面积极的影响。

　　此外，青春不仅是自我提高的时期，也是贡献的时期。作为年轻人，我们能够在世界上产生影响，无论我们的贡献是多小或多大。通过志愿服务、倡导重要事业或简单地成为那些需要帮助的人的好朋友，我们可以对他人的生活产生积极的影响，为我们自己和身边的人创造更美好的未来。

　　总之，青春是一份珍贵的礼物，我们应该珍惜并充分利用。让我们以热情、决心和同情心抓住这个时期。我们也要记住，我们的青春不会永远存在，我们今天所做出的决定和行动将塑造我们明天的人生。

　　谢谢。

dear students：

　　our way of life is always sunny, blue skies, which in the end the most dazzling ray of sunlightit was said to be excellent academic performance, it was said to be given to help others....and i think that our way of life of the most brilliant sunshine should be reported to belong to the temple map, help us to grow thanks to everyone.

　　yes, the institute of thanksgiving is a feeling, the institute of thanksgiving, but also a character. as teachers and our students, the most important gratitude is a school. schools to give us a big growth stage of life: bright and spacious classrooms, new desks and chairs, air-conditioned and well-being, as well as multi-media facilities, has provided us with an attractive learning environment. read one book bright and clean rooms, provides us with knowledge of the marine tour; flat beautiful big playground, provided us with a good place for the exercise, and pottery room, computer room, dance room, multi-purpose hall, and so on, no school is not out of devotion to our selfless love!

　　however, in these beautiful places, often with some notes of discord. read books in one room, some students read the book, abandonment, i do not know the original release, there is more tear, using the phenomenon of the book; when the red and green and white artificial big playground to open it selfless embrace, and some of the scenes of discord hurt our eyes: a wide range of confetti, colorful tang zhi, and scattered in all corners of the shell seeds, chewing gum, etc. the list goes on of these!

　　students, please put your hand on his chest ask ourselves: "i do a thanksgiving schoolstudents, let us now work together, with their good health habits to school thanksgiving, thanksgiving, so that the flowers on campus and open more beautiful.

亲爱的同学们：

　　我们的人生之路总是阳光明媚,晴空万里，到底哪一缕阳光最耀眼？有人说是优异的学习成绩，有人说是给予别人帮助……而我认为在我们的人生路上最灿烂的阳光应该属于知恩图报，感谢帮助我们成长的每一个人。

　　是的，学会感恩，是一种情怀,学会感恩，更是一种情操.作为教师和学生的我们，最要感恩的就是学校了。学校给我们了一个人生成长的大舞台：宽敞明亮的教室，崭新的桌椅，冷暖空调、以及多媒体设施，为我们提供了一个优美的学习环境。窗明几净的图书阅览一体室，为我们提供了畅游知识的海洋；平坦美丽的`大操场，为我们提供了锻炼身体的好去处，还有陶艺室，电脑室、舞蹈室、多功能报告厅等等，无不是学校对我们奉献出的无私的爱！

　　可是，在这些美丽的地方，却常常有着一些不和谐的音符。在图书阅览一体室，有的同学看完书后，乱扔乱放，不知道放回原处，更有甚者还有撕书、拿书的现象；当红绿相间的人工大操场向我们敞开它无私的怀抱时，又有一些不和谐的景象刺痛了我们的眼睛：各种各样的纸屑，五颜六色的糖纸，还有散落在各个角落的瓜子壳、口香糖等等这些举不胜举！同学们，请你把手放在自己的胸口扪心自问：“我感恩学校了吗？”

　　同学们，就让我们共同努力吧，用自己良好的卫生习惯来感恩学校，让感恩的花儿在校园内开放的更加美丽。
