the four freedoms
franklin delano roosevelt
in the future days, which we seek to make secure, we look forward to a world founded upon four essential human freedoms.
the first is freedom of speech and expression -- everywhere in the world.
the second is freedom of every person to worship god in his own way -- everywhere in the world.
the third is freedom from want, which, translated into world terms, means economic understandings which will secure to every nation a
healthy peacetime life for its inhabitants -- everywhere in the world. the fourth is freedom from fear, which, translated into world terms, means a world-wide reduction of armaments to such a point and in such a thorough fashion that no nation will be in a position to mit an act of physical aggression against any neighbor -- anywhere in the world. that is no vision of a distant millennium. it is a definite basis for a kind of world attainable in our own time and generation. that kind of world is the very antithesis of the so-called “new order” of tyranny which the dictators seek to create with the crash of a bomb. to that new order we oppose the greater conception -- the moral order. a good society is able to face schemes of world domination and foreign revolutions alike without fear.
since the beginning of our american history we have been engaged in change, in a perpetual, peaceful revolution, a revolution which goes on steadily, quietly, adjusting itself to changing conditions without the concentration camp or the quicklime in the ditch. the world order which we seek is the cooperation of free countries, working together in a friendly, civilized society.
this nation has placed its destiny in the hands and heads and hearts of its millions of free men and women, and its faith in freedom under the guidance of god. freedom means the supremacy of human rights
everywhere. our support goes to those who struggle to gain those rights and keep them. our strength is our unity of purpose.
to that high concept there can be no end save victory.

大学生英文演讲稿:从跌倒的地方站起来 let’s stand up from where we fall down all the celebrations weling the new century were hold in the year 2014, because life without a greeting is like the sky without the sun.greetings are very important for the whole world,in my opinion. but i dont know whether greetings are enough for us.especially when we meet with failures .i remember quite clearly that when i was a child,if i fall down and was on the brink of crying,my father always told me\stand up from where you fall down!\fall down. that was a special mid night in 1993.expectations filled our hearts. we stared at the tv,hoping excitedly as the voice would fly to our ears. but at last,each chinese who loves our motherland was
distressed to know the result:beijing ,lost to sydeny by a margin of two votes in the olympic hosting petition. eight years have past,but the frustration has not healed with time at all. now,at the begining of the new millennium,all of the pride and disappointment of the 20th century had gone with the wind. the 21st century,which is full of hope,longing znd thought has e. someone said,we would start from zero on. should i really start from zero on? no!i hold that we should go on with our efferts and ambitions stayed by last century,and make our life better. \captital,a 3,000 -year-old city these days. beijing,along with paris,istanbul,osake and toronto,has been shortlisted by the
international olympic mittee as an official candidate city for the 2014 olympic games. this is beijings second attempt to host the games.
everyone fully supports beijings bid for it. maybe,we can paint fences along the main roads of beijing. maybe,we can make much of yhe city cleaned up. maybe,we can learn and speak basic english idioms and
expressions for daily munication. but,but are they just enough? facing the new century,mankind is driven by the revolution of science and technoiogy,world economy is undergoing broud and profound changes. but nobody can deny the fact that pared with developed nations,developing countries are confronted with more pressure and challenges.in order to bee famous in the world,we must speed up our international economic restructuring to catch up with industrialized nations. supporting
beijings bid is a systematic project that can support chinasdevelopment efforts. i believe recycled pa-pe-r,clean fuel,sorted rubbish,water-saving and enery-efficient facilities will bee reality in the ing years for china. i believe the new century is an era of learning ans
teaching,and lifelong education has bee one of the main trends in the future developmet of chinese society. i believe that,on july 13,our dream of beijings olympic bid will bee true. because to millions of chinese,for china to have the gloal respect and support that she
deserves is not just a dream. it is a part of our very souls.for we are not only equal members of our motherland, china,but we are also equal contributors to the world as a whole. let us stand together,all nations in beijing,in brotherhood,friendship and peace, in 2014 and forever! 第三篇：化工类专业英语推荐下载 subject-based english propanol 丙醇
