Anna Howard Shaw: The Fundamental Principle of a Republic delivered 1915, New York State Referendum, Albany, New York When I came into your hall tonight, I thought of the last time I was in your city. Twenty-one years ago I came here with Susan B. Anthony, and we came for exactly the same purpose as that for which we are here tonight. Boys have been born since that time and have become voters, and the women are still trying to persuade American men to believe in the fundamental principles of democracy, and I never quite feel as if it was a fair field to argue this question with men, because in doing it you have to assume that a man who professes to believe in a Republican form of government does not believe in a Republican form of government, for the only thing that woman's enfranchisement means at all is that a government which claims to be a Republic should be a Republic, and not an aristocracy. The difficulty with discussing this question with those who oppose us is that they make any number of arguments but none of them have anything to do with Woman's Suffrage; they always have something to do with something else, therefore the arguments which we have to make rarely ever have anything to do with the subject, because we have to answer our opponents who always escape the subject as far as possible in order to have any sort of reason in connection with what they say. Now one of two things is true: either a Republic is a desirable form of government, or else it is not. If it is, then we should have it, if it is not then we ought not to pretend that we have it. We ought at least be true to our ideals, and the men of New York have for the first time in their lives, the rare opportunity on the second day of next November, of making the state truly a part of the Republic. It is the greatest opportunity which has ever come to the men of the state. They have never had so serious a problem to solve before, they will never have a more serious problem to solve in any future of our nation's life, and the thing that disturbs me more than anything else in connection with it is that so few people realize what a profound problem they have to solve on November 2. It is not merely a trifling matter; it is not a little thing that does not concern the state, it is the most vital problem we could have, and any man who goes to the polls on the second day of next November without thoroughly informing himself in regard to this subject is unworthy to be a citizen of this state, and unfit to cast a ballot. If woman's suffrage is wrong, it is a great wrong; if it is right, it is a profound and fundamental principle, and we all know, if we know what a Republic is, that it is the fundamental principle upon which a Republic must rise. Let us see where we are as a people; how we act here and what we think we are. The difficulty with the men of this country is that they are so consistent in their inconsistency that they are not aware of having been inconsistent; because their consistency has been so continuous and their inconsistency so consecutive that it has never been broken, from the beginning of our Nation's life to the present time. If we trace our history back we will find that from the very dawn of our existence as a people, men have

英语演讲稿开场白【三篇】 篇一 经典英语演讲开场白范文： 1.We are drowning in news. Reuters alone puts out three-and-a-half million news stories a year. That’s just one source. My question is: How many of those stories are actually going to matter in the long run? That’s the idea behind The Long News. It’s a project by The Long Now Foundation, which was founded by TED stars including Kevin Kelly and Stewart Brand. And what we’re looking for is news stories that might still matter 50 or 100 or 10,000 years from now. And when you look at the news through that filter, a lot falls by the wayside. 2.Thank you. Thank you so much. Thank you. Thank you, General Caslen, for that introduction. General Trainor, General Clarke, faculty and staff at West Point, you have been outstanding stewards of this proud institution and outstanding mentors for the newest officers in the United States Army.

美国经典英文演讲100篇:Civil Rights Address John F. Kennedy Civil Rights Address Good evening, my fellow citizens: This afternoon, following a series of threats and defiant statements, the presence of Alabama National Guardsmen was required on the University of Alabama to carry out the final and unequivocal order of the United States District Court of the Northern District of Alabama. That order called for the admission of two clearly qualified young Alabama residents who happened to have been born Negro. That they were admitted peacefully on the campus is due in good measure to the conduct of the students of the University of Alabama, who met their responsibilities in a constructive way. I hope that every American, regardless of where he lives, will stop and examine his conscience about this and other related incidents. This Nation was founded by men of many nations and backgrounds. It was founded on the principle that all men are created equal, and that the rights of every man are diminished when the rights of one man are threatened.
经典英语演讲稿带翻译范文(2) 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. 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 freshneof the deep spring of life. 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. 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. 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.

经典英文演讲_45 Mario Cuomo: "A Tale of Two Cities" On behalf of the Empire State and the family of New York, I thank you for the great privilege of being able to address this convention. Please allow me to skip the stories and the poetry and the temptation to deal in nice but vague rhetoric. Let me instead use this valuable opportunity to deal immediately with questions that should determine this election and that we all know are vital to the American people. Ten days ago, President Reagan admitted that although some people in this country seemed to be doing well nowadays, others were unhappy, even worried, about themselves, their families and their futures. The president said that he didn't understand that fear. He said, "Why, this country is a shining city on a hill." And the president is right. In many ways we are a shining city on a hill. But the hard truth is that not everyone is sharing in this city's splendor and glory. A shining city is perhaps all the president sees from the portico of the White House and the veranda of his ranch, where everyone seems to be doing well. But there's another city; there's another part to the shining the city; the part where some people can't pay their mortgages, and most young people can't afford one, where students can't afford the education they need, and middle-class parents watch the dreams they hold for their children evaporate. In this part of the city there are more poor than ever, more families in trouble, more and more people who need help but can't find it. Even worse: There are elderly people who tremble in the basements of the houses there. And there are people who sleep in the city streets, in the gutter, where the glitter doesn't show. There are ghettos where thousands of young people, without a job or an education, give their lives away to drug dealers every day. There is despair, Mr. President, in the faces that you don't see, in the places that you don't visit in your shining city. In fact, Mr. President, this is a nation --. Mr. President you ought to know that this nation is more a "Tale of Two Cities" than it is just a "Shining City on a Hill." Maybe, maybe, Mr. President, if you visited some more places. Maybe if you went to Appalachia where some people still live in sheds, maybe if you went to Lackawanna where thousands of unemployed steel workers wonder why we subsidized foreign steel. Maybe, maybe, Mr. President, if you stopped in at a shelter in Chicago and spoke to the homeless there; maybe, Mr. President, if you asked a woman who had been denied the help she needed to feed her children because you said you needed the money for a tax break for a millionaire or for a missile we couldn't afford to use.
教你如何看懂集成电路的线路图 集成电路应用电路图具有以下功能： 1.它表达了集成电路各引脚外电路结构、元器件参数等，从而表示了某一集成电路的完整工作情况。 2.有些集成电路应用电路中，画出了集成电路的内电路方框图，这时对分析集成电路应用电路是相当方便的，但这种表示方式不多。 3.集成电路应用电路有典型应用电路和实用电路两种，前者在集成电路手册中可以查到，后者出现在实用电路中，这两种应用电路相差不大，根据这一特点，在没有实际应用电路图时可以用典型应用电路图作参考，这一方法修理中常常采用。 4.一般情况集成电路应用电路表达了一个完整的单元电路，或一个电路系统，但有些情况下一个完整的电路系统要用到两个或更多的集成电路。 集成电路应用电路具有以下特点： 1.大部分应用电路不画出内电路方框图，这对识图不利，尤其对初学者进行电路工作分析时更为不利。 2.对初学者而言，分析集成电路的应用电路比分析分立元器件的电路更为困难，这是对集成电路内部电路不了解的原缘，实际上识图也好、修理也好，集成电路比分立元器件电路更为方便。 3.对集成电路应用电路而言，大致了解集成电路内部电路和详细了解各引脚作用的情况下，识图是比较方便的。这是因为同类型集成电路具有规律性，在掌握了它们的共性后，可以方便地分析许多同功能不同型号的集成电路应用电路。 集成电路的方法和注意事项主要以下几点： 1.了解各引脚的作用是识图的关键了解各引脚的作用可以查阅有关集成电路应用手册。知道了各引脚作用之后，分析各引脚外电路工作原理和元器件作用就方便了。例如：知道①脚是输入引脚，那么与①脚所串联的电容是输入端耦合电路，与①脚相连的电路是输入电路。 2.了解集成电路各引脚作用的三种方法了解集成电路各引脚作用有三种方法：一是查阅有关资料;二是根据集成电路的内电路方框图分析;三是根据集成电路的应用电路中各引脚外电路特征进行分析。对第三种方法要求有比较好的电路分析基础。 3.集成电路应用电路分析步骤如下： ①直流电路分析。这一步主要是进行电源和接地引脚外电路的分析。
