题目：Should parents set limits in internet access for their teenage children? Why?
Internet is dangerous if a child has unlimited freedom to use it. Because teenagers are too weak to resist the great tempt. Various online games will cost their almost all-day time. And many kinds of online movies may teach them unhealthy content such as violence. Also, long-time exposure to computer will do great harm to teenager's eyesight. A child addicted to Internet will neglect his study completely. However, the word limit does not mean forbidding. It can't be denied that internet is a very useful tool for learning. In this information age, computer and internet is essential. Adequate access to internet will contribute to teenagers keeping pace with this world. Also, internet is a fine entertainment for students who have study longtime and get tired. So, I think parents should set limits on but not forbid access for their teenager children.
题目：the next twenty years from now on, students will not use printed books any more.
I don't think so. printed books won't be abandoned in such a short time. I admit that new technology is developing fast. Many advanced electronic products are gradually take the place of traditional tools. Just like in university, teachers like to use multimedia in class for it is quite convenient and efficient. However, for our student, it is not realistic to study completely by electronic products. There are many things need to recorded on books. Books are something meaningful and practical. I should say, in our country, printed books wouldn't be abandoned within 20 years at least for two reasons. Firstly, books are classical container of knowledge. They accompany human to advance. A student without books could be someway ridiculous. Secondly, our country haven't developed so strong to make every student study by computer or other forms of electronic tools. And even after 20 years, the possibility is also very small. I also think it is unnecessary because books are cheap but useful and still meaningful.
The ceremonies honoring the fortieth anniversary of D day became more than commemorations. They became celebrations of heroism and sacrifice.
This place, Pointe du Hoc, in itself was moving and majestic. I stood there on that windswept point with the ocean behind me. Before me were the boys who forty years before had fought their way up from the ocean. Some rested under the white crosses and Stars of David that stretched out across the landscape. Others sat right in front of me. They looked like elderly businessmen, yet these were the kids who climbed the cliffs.*
We're here to mark that day in history when the Allied armies joined in battle to reclaim this continent to liberty. For four long years, much of Europe had been under a terrible shadow. Free nations had fallen, Jews cried out in the camps, millions cried out for liberation. Europe was enslaved, and the world prayed for its rescue. Here, in Normandy, the rescue began. Here, the Allies stood and fought against tyranny, in a giant undertaking unparalleled in human history.
We stand on a lonely, windswept point on the northern shore of France. The air is soft, but forty years ago at this moment, the air was dense with smoke and the cries of men, and the air was filled with the crack of rifle fire and the roar of cannon. At dawn, on the morning of the 6th of June, 1944, two hundred and twenty-five Rangers jumped off the British landing craft and ran to the bottom of these cliffs.
Their mission was one of the most difficult and daring of the invasion: to climb these sheer and desolate cliffs and take out the enemy guns. The Allies had been told that some of the mightiest of these guns were here, and they would be trained on the beaches to stop the Allied advance.
The Rangers looked up and saw the enemy soldiers at the edge of the cliffs, shooting down at them with machine guns and throwing grenades. And the American Rangers began to climb. They shot rope ladders over the face of these cliffs and began to pull themselves up. When one Ranger fell, another would take his place. When one rope was cut, a Ranger would grab another and begin his climb again. They climbed, shot back, and held their footing. Soon, one by one, the Rangers pulled themselves over the top, and in seizing the firm land at the top of these cliffs, they began to seize back the continent of Europe. Two hundred and twenty-five came here. After two days of fighting, only ninety could still bear arms.
And behind me is a memorial that symbolizes the Ranger daggers that were thrust into the top of these cliffs. And before me are the men who put them here. These are the boys of Pointe du Hoc. These are the men who took the cliffs. These are the champions who helped free a continent. These are the heroes who helped end a war. Gentlemen, I look at you and I think of the words of Stephen Spender's poem. You are men who in your "lives fought for life and left the vivid air signed with your honor."
I think I know what you may be thinking right now -- thinking "we were just part of a bigger effort; everyone was brave that day." Well everyone was. Do you remember the story of Bill Millin of the 51st Highlanders? Forty years ago today, British troops were pinned down near a bridge, waiting desperately for help. Suddenly, they heard the sound of bagpipes, and some thought they were dreaming. Well, they weren't. They looked up and saw Bill Millin with his bagpipes, leading the reinforcements and ignoring the smack of the bullets into the ground around him.
We will pray forever that someday that changing will come. But for now, particularly today, it is good and fitting to renew our commitment to each other, to our freedom, and to the alliance that protects it.
Lord Lovat was with him -- Lord Lovat of Scotland, who calmly announced when he got to the bridge, "Sorry, I'm a few minutes late," as if he'd been delayed by a traffic jam, when in truth he'd just come from the bloody fighting on Sword Beach, which he and his men had just taken.
There was the impossible valor of the Poles, who threw themselves between the enemy and the rest of Europe as the invasion took hold; and the unsurpassed courage of the Canadians who had already seen the horrors of war on this coast. They knew what awaited them there, but they would not be deterred. And once they hit Juno Beach, they never looked back.
All of these men were part of a roll call of honor with names that spoke of a pride as bright as the colors they bore; The Royal Winnipeg Rifles, Poland's 24th Lancers, the Royal Scots Fusiliers, the Screaming Eagles, the Yeomen of England's armored divisions, the forces of Free France, the Coast Guard's "Matchbox Fleet," and you, the American Rangers.
Forty summers have passed since the battle that you fought here. You were young the day you took these cliffs; some of you were hardly more than boys, with the deepest joys of life before you. Yet you risked everything here. Why? Why did you do it? What impelled you to put aside the instinct for self-preservation and risk your lives to take these cliffs? What inspired all the men of the armies that met here? We look at you, and somehow we know the answer. It was faith and belief. It was loyalty and love.
The men of Normandy had faith that what they were doing was right, faith that they fought for all humanity, faith that a just God would grant them mercy on this beachhead, or on the next. It was the deep knowledge -- and pray God we have not lost it -- that there is a profound moral difference between the use of force for liberation and the use of force for conquest. You were here to liberate, not to conquer, and so you and those others did not doubt your cause. And you were right not to doubt.
You all knew that some things are worth dying for. One's country is worth dying for, and democracy is worth dying for, because it's the most deeply honorable form of government ever devised by man. All of you loved liberty. All of you were willing to fight tyranny, and you knew the people of your countries were behind you.
The Americans who fought here that morning knew word of the invasion was spreading through the darkness back home. They fought -- or felt in their hearts, though they couldn't know in fact, that in Georgia they were filling the churches at 4:00 am. In Kansas they were kneeling on their porches and praying. And in Philadelphia they were ringing the Liberty Bell.
Something else helped the men of D-day; their rock-hard belief that Providence would have a great hand in the events that would unfold here; that God was an ally in this great cause. And so, the night before the invasion, when Colonel Wolverton asked his parachute troops to kneel with him in prayer, he told them: "Do not bow your heads, but look up so you can see God and ask His blessing in what we're about to do." Also, that night, General Matthew Ridgway on his cot, listening in the darkness for the promise God made to Joshua: "I will not fail thee nor forsake thee."
We will pray forever that someday that changing will come. But for now, particularly today, it is good and fitting to renew our commitment to each other, to our freedom, and to the alliance that protects it.
These are the things that impelled them; these are the things that shaped the unity of the Allies.
When the war was over, there were lives to be rebuilt and governments to be returned to the people. There were nations to be reborn. Above all, there was a new peace to be assured. These were huge and daunting tasks. But the Allies summoned strength from the faith, belief, loyalty, and love of those who fell here. They rebuilt a new Europe together. There was first a great reconciliation among those who had been enemies, all of whom had suffered so greatly. The United States did its part, creating the Marshall Plan to help rebuild our allies and our former enemies. The Marshall Plan led to the Atlantic alliance -- a great alliance that serves to this day as our shield for freedom, for prosperity, and for peace.
In spite of our great efforts and successes, not all that followed the end of the war was happy or planned. Some liberated countries were lost. The great sadness of this loss echoes down to our own time in the streets of Warsaw, Prague, and East Berlin. The Soviet troops that came to the center of this continent did not leave when peace came. They're still there, uninvited, unwanted, unyielding, almost forty years after the war. Because of this, allied forces still stand on this continent. Today, as forty years ago, our armies are here for only one purpose: to protect and defend democracy. The only territories we hold are memorials like this one and graveyards where our heroes rest.
We in America have learned bitter lessons from two world wars. It is better to be here ready to protect the peace, than to take blind shelter across the sea, rushing to respond only after freedom is lost. We've learned that isolationism never was and never will be an acceptable response to tyrannical governments with an expansionist intent. But we try always to be prepared for peace, prepared to deter aggression, prepared to negotiate the reduction of arms, and yes, prepared to reach out again in the spirit of reconciliation. In truth, there is no reconciliation we would welcome more than a reconciliation with the Soviet Union, so, together, we can lessen the risks of war, now and forever.
It's fitting to remember here the great losses also suffered by the Russian people during World War II: 20 million perished, a terrible price that testifies to all the world the necessity of ending war. I tell you from my heart that we in the United States do not want war. We want to wipe from the face of the earth the terrible weapons that man now has in his hands. And I tell you, we are ready to seize that beachhead. We look for some sign from the Soviet union that they are willing to move forward, that they share our desire and love for peace, and that they will give up the ways of conquest. There must be a changing there that will allow us to turn our hope into action.
We're bound today by what bound us 40 years ago, the same loyalties, traditions, and beliefs. We're bound by reality. The strength of America's allies is vital to the United States, and the American security guarantee is essential to the continued freedom of Europe's democracies. We were with you then; we are with you now. Your hopes are our hopes, and your destiny is our destiny.
Here, in this place where the West held together, let us make a vow to our dead. Let us show them by our actions that we understand what they died for. Let our actions say to them the words for which Matthew Ridgway listened: "I will not fail thee nor forsake thee."
Strengthened by their courage and heartened by their valor and borne by their memory, let us continue to stand for the ideals for which they lived and died.
Thank you very much, and God bless you all.
We observe today not a victory of party, but a celebration of freedom -- symbolizing an end, as well as a beginning -- signifying renewal, as well as change. For I have sworn before you and Almighty God the same solemn oath our forebears prescribed nearly a century and three-quarters ago.
The world is very different now. For man holds in his mortal hands the power to abolish all forms of human poverty and all forms of human life. And yet the same revolutionary beliefs for which our forebears fought are still at issue around the globe -- the belief that the rights of man come not from the generosity of the state, but from the hand of God.
We dare not forget today that we are the heirs of that first revolution. Let the word go forth from this time and place, to friend and foe alike, that the torch has been passed to a new generation of Americans -- born in this century, tempered by war, disciplined by a hard and bitter peace, proud of our ancient heritage, and unwilling to witness or permit the slow undoing of those human rights to which this nation has always been committed, and to which we are committed today at home and around the world.
Let every nation know, whether it wishes us well or ill, that we shall pay any price, bear any burden, meet any hardship, support any friend, oppose any foe, to assure the survival and the success of liberty.
This much we pledge -- and more.
To those old allies whose cultural and spiritual origins we share, we pledge the loyalty of faithful friends. United there is little we cannot do in a host of cooperative ventures. Divided there is little we can do -- for we dare not meet a powerful challenge at odds and split asunder.
To those new states whom we welcome to the ranks of the free, we pledge our word that one form of colonial control shall not have passed away merely to be replaced by a far more iron tyranny. We shall not always expect to find them supporting our view. But we shall always hope to find them strongly supporting their own freedom -- and to remember that, in the past, those who foolishly sought power by riding the back of the tiger ended up inside.
To those people in the huts and villages of half the globe struggling to break the bonds of mass misery, we pledge our best efforts to help them help themselves, for whatever period is required -- not because the Communists may be doing it, not because we seek their votes, but because it is right. If a free society cannot help the many who are poor, it cannot save the few who are rich.
To our sister republics south of our border, we offer a special pledge: to convert our good words into good deeds, in a new alliance for progress, to assist free men and free governments in casting off the chains of poverty. But this peaceful revolution of hope cannot become the prey of hostile powers. Let all our neighbors know that we shall join with them to oppose aggression or subversion anywhere in the Americas. And let every other power know that this hemisphere intends to remain the master of its own house.
To that world assembly of sovereign states, the United Nations, our last best hope in an age where the instruments of war have far outpaced the instruments of peace, we renew our pledge of support -- to prevent it from becoming merely a forum for invective, to strengthen its shield of the new and the weak, and to enlarge the area in which its writ may run.
Finally, to those nations who would make themselves our adversary, we offer not a pledge but a request: that both sides begin anew the quest for peace, before the dark powers of destruction unleashed by science engulf all humanity in planned or accidental self-destruction.
We dare not tempt them with weakness. For only when our arms are sufficient beyond doubt can we be certain beyond doubt that they will never be employed.
But neither can two great and powerful groups of nations take comfort from our present course -- both sides overburdened by the cost of modern weapons, both rightly alarmed by the steady spread of the deadly atom, yet both racing to alter that uncertain balance of terror that stays the hand of mankind's final war. So let us begin anew -- remembering on both sides that civility is not a sign of weakness, and sincerity is always subject to proof. Let us never negotiate out of fear, but let us never fear to negotiate.
Let both sides explore what problems unite us instead of belaboring those problems which divide us.
Let both sides, for the first time, formulate serious and precise proposals for the inspection and control of arms, and bring the absolute power to destroy other nations under the absolute control of all nations.
Let both sides seek to invoke the wonders of science instead of its terrors. Together let us explore the stars, conquer the deserts, eradicate disease, tap the ocean depths, and encourage the arts and commerce.
Let both sides unite to heed, in all corners of the earth, the command of Isaiah -- to "undo the heavy burdens, and [to] let the oppressed go free."¹
And, if a beachhead of cooperation may push back the jungle of suspicion, let both sides join in creating a new endeavor -- not a new balance of power, but a new world of law -- where the strong are just, and the weak secure, and the peace preserved.
All this will not be finished in the first one hundred days. Nor will it be finished in the first one thousand days; nor in the life of this Administration; nor even perhaps in our lifetime on this planet. But let us begin.
In your hands, my fellow citizens, more than mine, will rest the final success or failure of our course. Since this country was founded, each generation of Americans has been summoned to give testimony to its national loyalty. The graves of young Americans who answered the call to service surround the globe.
Now the trumpet summons us again -- not as a call to bear arms, though arms we need -- not as a call to battle, though embattled we are -- but a call to bear the burden of a long twilight struggle, year in and year out, "rejoicing in hope; patient in tribulation,"² a struggle against the common enemies of man: tyranny, poverty, disease, and war itself.
Can we forge against these enemies a grand and global alliance, North and South, East and West, that can assure a more fruitful life for all mankind? Will you join in that historic effort?
In the long history of the world, only a few generations have been granted the role of defending freedom in its hour of maximum danger. I do not shrink from this responsibility -- I welcome it. I do not believe that any of us would exchange places with any other people or any other generation. The energy, the faith, the devotion which we bring to this endeavor will light our country and all who serve it. And the glow from that fire can truly light the world.
And so, my fellow Americans, ask not what your country can do for you; ask what you can do for your country.
My fellow citizens of the world, ask not what America will do for you, but what together we can do for the freedom of man.
Finally, whether you are citizens of America or citizens of the world, ask of us here the same high standards of strength and sacrifice which we ask of you. With a good conscience our only sure reward, with history the final judge of our deeds, let us go forth to lead the land we love, asking His blessing and His help, but knowing that here on earth God's work must truly be our own.
题目：working together is better than working alone.
I think work together is better than work alone. There are many benefits of working together. Firstly and obviously, working together can collect many useful and excellent ideas especially when we are thinking some complicated problems. After all, each person has his own way of thinking. After getting all ideas together, you will often find that things become much easier. Secondly, working together can avoid mistakes to a great extent. People may make wrong judge when their mood is not stable. In this case, teamwork will do great favor. Your partner could remind you of your mistake and turn the result to a good one. Thirdly, when we work together, we need be patient and not self-centered. You need to listen to others?opinion and learn to get well along with people around you.?opinion and learn to get well along with people around you.
