二、特朗普职演讲说了什么？
一句话总结：实现美国优先，买美国货，雇美国员工。
特朗普发表就职演讲，他表示，“美国人民联合在一起 ，要重建我们的国家，我们会改变美国的未来和历史的未来。”他表示接下来无论什么事务，都会以美国人为优先考量。特朗普称不会让人民失望，将把工作带回美国，重新守卫住边境，夺回美国的财富并重新找回美国人民的梦想，“美国会再次开始赢得胜利，见证前所未有的繁荣”。
对于如何实现美国优先，特朗普给出了自己的答案：一是要购买美国的产品，二是要雇佣美国的员工。
十句话看完特朗普演讲
①今天，我们是将权力从华盛顿交回到了你们的手中，交回到了人民的手中。
②长久以来，华盛顿的一小部分政客攫取了利益果实，而让人民背负了沉重的代价。华盛顿繁荣了起来，但是人民群众却没有分享到财富。政客们腰包鼓起来了，但后果却是工作流失、工厂倒闭。这一切都会从此时此刻开始改变。”
③2017年1月20日，这一天将会被历史铭记，美国人民再次成为这个国家的统治者。曾经被国家遗忘的人们，不会再被忽视。
④数十年以来，我们以美国工业衰落为代价而供养着外国兴旺发达的工业，我们资助别国军队的发展却忽略了自己军队的消耗。
⑤我们让其他国家变得富裕，而我们自己国家的力量、财富和信心却是消失殆尽。工厂一个接一个倒闭离开美国了，毫不顾忌数以百万计的被遗弃的美国劳动人民。
⑥从今天起，一个新的愿景将指引我们的国家。从今天起，我们将把美国置于首位，只有美国第一。
⑦我们将用美国人的双手，美国人的劳动，来重新建设这个国家。我们将会遵循两个简单的准则，买美国货，雇佣美国工人。
⑧我们不会接受那些只说不做、一直满口抱怨但不采取任何实际行动的政客。那些空谈的时代已然结束，现在到了行动的时间。
⑨我们在加强巩固与传统盟友的合作伙伴关系的同时也会建立新的联盟。我们期望文明国家能聚在一起，共同抵御恐怖主义，让它从地球上消失。
⑩我们举国同心，一定会让美国再次强大，让美国再次繁荣富裕，让美国再次为自己自豪，让美国再次安全。是的，我们会携手一致，让美国更加强大。

英文演讲原文：
Chief Justice Roberts, President Carter, President Clinton, President Bush, President Obama, fellow Americans and people of the world, thank you.
We, the citizens of America, are now joined in a great national effort to rebuild our country and restore its promise for all of our people. Together we will determine the course of America and the world for many, many years to come.
We will face challenges. We will confront hardships. But we will get the job done. Every four years, we gather on these steps to carry out the orderly and peaceful transfer of power.
And we are grateful to President Obama and First Lady Michelle Obama for their gracious aid throughout this transition. They have been magnificent. Thank you.
Today's ceremony, however, has very special meaning. Because today, we are not merely transferring power from one administration to another or from one party to another.
But we are transferring power from Washington D.C. and giving it back to you, the people.
For too long, a small group in our nation's capital has reaped the rewards of government while the people have borne the cost. Washington flourished, but the people did not share in its wealth. Politicians prospered, but the jobs left. And the factories closed.
The establishment protected itself but not the citizens of our country. Their victories have not been your victories. Their triumphs have not been your triumphs. And while they celebrated in our nation’s capital, there was little to celebrate for struggling families all across our land. That all changes starting right here and right now. Because this moment is your moment. It belongs to you.
It belongs to everyone gathered here today and everyone watching all across America. This is your day. This is your celebration. And this, the United States of America, is your country.
What truly matters is not which party controls our government but whether our government is controlled by the people. January 20th, 2017 will be remembered as the day the people became the rulers of this nation again.
The forgotten men and women of our country will be forgotten no longer.
Everyone is listening to you now. You came by the tens of millions to become part of a historic movement, the likes of which the world has never seen before.
At the center of this movement is a crucial conviction -- that a nation exist to serve its citizens. Americans want great schools for their children, safe neighborhoods for their families and good jobs for themselves.
These are just and reasonable demands of righteous people and a righteous public. But for too many of our citizens, a different reality exist. Mothers and children trapped in poverty in our inner cities, rusted out factories scattered like tombstones across the landscape of our nation, an education system flushed with cash but which leaves our young and beautiful students deprived of all knowledge. And the crime, and the gangs, and the drugs that have stolen too many lives and robbed our country of so much unrealized potential. This American carnage stops right here and stops right now.
We are one nation, and their pain is our pain. Their dreams are our dreams, and their success will be our success. We share one heart, one home and one glorious destiny.
The oath of office I take today is an oath of allegiance to all Americans. For many decades, we've enriched foreign industry at the expense of American industry, subsidized the armies of other countries while allowing for the very sad depletion of our military.
We defended other nation’s borders while refusing to defend our own.
And spent trillions and trillions of dollars overseas while America's infrastructure has fallen into disrepair and decay.
We've made other countries rich while the wealth, strength, and confidence of our country has dissipated over the horizon. One by one, the factories shuttered and left our shores with not even a thought about the millions and millions of American workers that were left behind.
The wealth of our middle class has been ripped from their homes and then redistributed all across the world.
But that is the past and now we are looking only to the future.
We assembled here today are issuing a new decree to be heard in every city, in every foreign capital and in every hall of power. From this day forward, a new vision will govern our land. From this day forward, it's going to be only America first -- America first.
Every decision on trade, on taxes, on immigration, on foreign affairs will be made to benefit American workers and American families. We must protect our borders from the ravages of other countries making our products, stealing our companies and destroying our jobs.
Protection will lead to great prosperity and strength. I will fight for you with every breath in my body. And I will never, ever let you down.
America will start winning again, winning like never before.
We will bring back our jobs. We will bring back our borders. We will bring back our wealth, and we will bring back our dreams. We will build new roads and highways and bridges and airports and tunnels and railways all across our wonderful nation. We will get our people off of welfare and back to work rebuilding our country with American hands and American labor. We will follow two simple rules -- buy American and hire American.
We will seek friendship and goodwill with the nations of the world.
But we do so with the understanding that it is the right of all nations to put their own interests first. We do not seek to impose our way of life on anyone but rather to let it shine as an example. We will shine for everyone to follow.
We will reinforce old alliances and form new ones. And unite the civilized world against radical Islamic terrorism, which we will eradicate completely from the face of the earth.
At the bedrock of our politics will be a total allegiance to the United States of America and through our loyalty to our country, we will rediscover our loyalty to each other. When you open your heart to patriotism, there is no room for prejudice.
The Bible tells us how good and pleasant it is when God's people live together in unity. We must speak our minds openly, debate our disagreement honestly but always pursue solidarity. When America is united, America is totally unstoppable.
There should be no fear. We are protected, and we will always be protected. And most importantly, We will be protected by the great men and women of our military and law enforcement. We will be protected by God.
Finally, we must think big and dream even bigger. In America, we understand that a nation is only living as long as it is striving. We will no longer accept politicians who are all talk and no action, constantly complaining but never doing anything about it.
The time for empty talk is over. Now arrives the hour of action.
Do not allow anyone to tell you that it cannot be done. No challenge can match the heart and fight and spirit of America. We will not fail. Our country will thrive and prosper again. We stand at the birth of a new millennium, ready to unlock the mysteries of space, to free the earth from the miseries of disease and to harness the energies, industries and technologies of tomorrow. A new national pride will stir ourselves, lift our sights and heal our divisions. It’s time to remember that old wisdom our soldiers will never forget -- that whether we are black or brown or white, we all bleed the same red blood of patriots.
We all enjoyed the same glorious freedoms, and we all salute the same great American flag.
And whether a child is born in the urban sprawl of Detroit or the windswept plains of Nebraska, They look up at the same night sky, they build a heart with the same dreams and they are infused with the breath of life by the same Almighty Creator.
So to all Americans in every city near and far, small and large, from mountain to mountain, from ocean to ocean, hear these words -- you will never be ignored again.
Your voice, your hopes and your dreams will define our American destiny. Together, And your courage and goodness and love will forever guide us along the way. We will make America strong again. We will make America wealthy again. We will make America proud again. We will make America safe again. And yes, together, thank you. we will make America great again. God bless you. And God bless America. Thank You.
