听力原文： Okay, uh, so this time we are talking about the American Dream. This nation o

f ours is unique. You may not realize it and most of us surely take it for granted. We may complain about the economy but just try explaining the Price Club to a Russian or a Cuban or a Nigerian! We may complain about our government or our President, but in how many other countries is the press free to report the leaders indiscretions？ We have so much and yet we complain so much...actually I think it is the ability to complain that makes America great. It is the freedom to dissent, to rally against the incumbent powers. This freedom to disagree is what makes us so special and it is this very freedom that is the very essence of America. What is the "American Dream"？ Surely, it is different for everyone. For some, it is wealth and power. For others, it is religious freedom and justice. For others, it may be a roof over their heads. How has this nation been able to provide these things...we shall see. First, the American Dream is values and ideals. They are things we stand for, things we feel are right and correct. In America our values and ideals are. justice, liberty, fairness, democracy, and equality. Maybe you will ask why is understanding what the American Dream is important？ You know, we vote and influence government via democracy, and we should know what this nation is supposed to be about before we make these serious decisions. And policies should be consistent with stated ideals. We have a responsibility to the nation and the world because our unique status as an economic and military superpower. How has the dream, our ideological roots, been created？ Mores, the values of a society, and culture developed over time. Our values have been shaped by our forefathers, and, of course, our foremothers! Our history and the legacy of those that came before have created our culture. Religion teaches values and influences us. Enlightenment thinkers from the 1600s, like John Locke, Montesquieu, Rousseau and Voltaire have had a great impact on our government and our political philosophy. The ideas expressed by the enlightenment thinkers were put to use in America through the Declaration of Independence, in which such ideas as, natural rights, consent of the governed, life, liberty and property, later changed to "pursuit of happiness" by Jefferson, and right to rebel are also mentioned. Student A I have read it before. Professor Could you tell the class what other documents reflect the idea of American Dreams？ Student A Yeah...Voltaire, 1st Amendment, the Freedom of Speech..."I may disagree with what you say but I will defend till death your right to say it!" Professor Anything else？ What about Montesquieu, Constitution？ I think this is the last thing you may neglect. Student A Oh, right. Separation of powers, checks and balances and dividing the government into three branches. Professor Good, and there are revolutionary ideas like those of John Adams, Thomas Jefferson and Thomas Paine, which created a nation out of rebellion. Dissent is the very basis of this nation, it is our heritage. And, er, ...immigrants have stocked this great nation. We are a nation of immigrants. We come from every continent and every nation. Immigrants come here for economic opportunity, religious freedom and to seek justice. These are our values because we are all the children of immigrants. They came to this island for their dreams. The Pilgrims wrote out their laws and created their government before they ever set foot in America so that the society would have a basis in law. This written "compact" was the foundation of their society. It illustrates the idea of consent of the governed because it was created by the governed. They all consented (agreed) to give up absolute and abject freedom in exchange for rule of law. John Locke wrote in the 1600s about the nature of government. He wrote: "In a state of nature, all men are free and equal." "In a state of nature, no man ought to harm another." "Man acquires property through the products of his labor." "In order to remedy inconveniences (problems) resulting from a state of nature ...men enter into contract, thereby creating a civil society.., to defend the natural rights of men. " "If a government violates the social contract.., it rebels against the people, and the people have the right to dissolve the government."This meant that government was created by the people and that people gave up absolute freedom in exchange for safety against problems. We call this concept "consent of the governed". Consent is given by what is referred to as a "social contract". This also says that if the government violates the social contract, the citizens have the right to remove the government, because it was the citizens that created the government. We call this notion the "right to rebel". These three concepts are the basic philosophical foundations of this nation.Narrator Listen to part of a talk in a history class.
