Scientists study the world in which we live. They do this by curiosity and they can become

excited upon making novel discoveries and by finding means to explain yet unsolved questions. But scientists are normally not selfish; they like to share their excitement with other people. They publish their findings so that these become widely accessible to all those interested. In fact, they communicate their results also in their own interest. Scientists are eager to talk with other scientists working on the same and similar problems. By exchanging results and ideas, they have a better chance of success and they can reach their goal more rapidly. Most often the objectives of their study, being it in the fields of physics, chemistry or biology, share the same properties anywhere in the world. The laws of nature are the same in Europe and in China. For this simple reason the dialogue between scientists does not stop at political borders. Wherever in the world a scientist finds a colleague exploring the same problem, an exchange of their knowledge can help them to advance their studies. For these reasons international collaboration between scientists is flourishing.

In the introductory chapter of her book, Anyon shares a personal story involving her fathe

r. Anyons brief discussion of her familys long history of involvement in radical social and political activism, and her commitment to anti-oppressive pedagogy, offers readers important insights into her social and political convictions. Toward the end of the chapter, Anyon explains that she sees her new book as a form. of "intervention" and struggle against social injustices. Anyon begins her book by examining the impact of macroeconomic policies including minimum wage, tax policies, housing, job training, educational policies and reform. initiatives. She argues that student underachievement, unequal funding of public schools and the high dropout rate among working class students and students of color are linked to macroeconomic policies that work toward maintaining and reproducing social inequities. She believes that the success of school reform. efforts depends in part on reforming macroeconomic policies at the state and federal level.

Here, then, is the problem which I present to you, stark and dreadful and inescapable; Sha

ll we put an end to the human race or shall mankind renounce war? People will not face this alternative because it is so difficult to abolish war. The abolition of war will demand distasteful limitations of national sovereignty. But what perhaps impedes understanding of the situation more than anything else is that the term "mankind" feels vague and abstract. People scarcely realize in imagination that the danger is to themselves and their children and their grandchildren, and not only to a dimly apprehended humanity. And so they hope that perhaps war may be allowed to continue provided modern weapons are prohibited. I am afraid this hope is illusory. Whatever agreements not to use hydrogen bombs had been reached in time of peace, they would no longer be considered binding in time of war, and both sides would set to work to manufacture hydrogen bombs as soon as war broke out, for if one side manufactured the bombs and the other did not, the side that manufactured them would inevitably be victorious...

And as part of the recovery plan, were making a historic commitment to innovation. The Rec

overy Act creates jobs doubling our capacity to generate renewable energy; building a new smart grid that carry electricity from coast to coast; laying down broadband lines and high-speed rail lines; and providing the largest boost in basic research in history to ensure that America leads in the breakthrough discoveries of the new century, just as we led in the last. Because thats what we do best in America—we turn ideas into inventions, and inventions into industries. Now, history should be our guide. The United States led the worlds economies in the 20th Century because we led the world in innovation. Today, the competition is keener; the challenge is tougher; and thats why innovation is more important than ever. Thats the key to good, new jobs in the 21st Century. Thats how we will ensure a high quality of life for this generation and future generations. With these investments, were planting the seeds of progress for our country, and good-paying, private-sector jobs for the American people.

In a world where the channels by which we interact and learn about one another are complet

ely transformed and in a world where actions have global impact, Expos are called to fulfill a new role, which is potentially more powerful than the one in the past. Today, to be effective platforms for education and progress, Expos must inspire and connect the actions of governments and civil society in their common effort to develop and implement sustainable solutions to the universal challenges we all face. Expos build bridges that connect different spheres of society. As such, they help promote ideas and initiatives with new policies, they foster the development of new forms of cooperation and, last but not least, they introduce a degree accountability for the actions of governmental institutions and civil society alike, as we are all called to contribute solutions to our common problems. This is why more recent Expos have elected the theme as their central core and organizing principle.

This is a period in which the old world is slowly but irreversibly changing and the contou

rs of a new one are just beginning to take shape. Traditional institutions are being challenged. Budgets are being squeezed. Families are being stressed. All of this flux and churning creates enormous anxiety. At times of change, we must stay true to the ideals and principles that are at the heart of the United Nations Charter and the Universal Declaration of Human Rights. Among those core values is tolerance. Our practice of tolerance must mean more than peaceful coexistence, crucial as that is. It must be an active understanding fostered through dialogue and positive engagement with others. This is especially critical in combating the discrimination that causes so much divisiveness, destruction and death. We all have a responsibility to protect those vulnerable to discrimination, whether based on race, religion, nationality, language, gender, sexual orientation or other factors. Practicing tolerance can serve as the antidote to prejudice and hatred.

第6题

Among the minds powers is one that comes of itself to many children and artists. It need n

ot be lost, to the end of his day, by anyone who has ever had it. This is the power of taking delight in a thing, rather than in anything, everything, not as a means to some other end, but just because it is what it is, as the lover dotes on whatever may be traits of the beloved object. A child in the full health of his mind will put his hand flat on the summer turf, feel it and give a little shiver of private glee at the elastic firmness of the globe. He is not thinking how it will do for some game or to feed sheep upon. That would be the way of the wooer whose mind runs on his mistresss money. The childs is sheer affection, the true ecstatic sense of the things inherent characteristics. No matter what the things may be, no matter what they are good or bad for, there they are, each with a thrilling unique look and feel of its own, like a face; the iron astringently cool under its paint, the painted wood familiarly warmer, the cold crumbling enchantingly down in the hands, with its little dry smell of the sun and of hot nettles; each common thing a personality marked by delicious differences.

I was afraid. The truth is, I was afraid the day I walked into Stanford. And I was afraid

the day I walked out. I was scared of leaving the protective bubble of this place for places unknown, during uncertain economic times. And I was scared of squandering the incredible gift of my Stanford experience on pursuits that werent commensurate with expectations I, and others, had of me. I was scared of not doing it all, of making irrevocable mistakes. If youre scared today, let me ask you this: What will you do with your fear? Will you let it become a motivator, or an inhibitor? You are the only one who can answer that. But what I can offer as guidance, and reassurance, is a story: the story of one Stanford grads process of stumbling and searching to find a place in the world, oftentimes in the face of her fears.

Happiness lies not in the mere possession of money; it lies in the joy of achievement, in

the thrill of creative effort. The joy, the moral stimulation of work no longer must be forgotten in the mad chase of evanescent profits. These dark days, my friends, will be worth all they cost us if they teach us that our true destiny is not to be ministered unto but to minister to ourselves, to our fellow men. Recognition of that falsity of material wealth as the standard of success goes hand in hand with the abandonment of the false belief that public office and high political position are to be valued only by the standards of pride of place and personal profit; and there must be an end to a conduct in banking and in business which too often has given to a sacred trust the likeness of callous and selfish wrong doing. Small wonder that confidence languishes, for it thrives only on honesty, on honor, on the sacredness of obligations, on faithful protection, on unselfish performance; without them it cannot live.

Liberty cannot be preserved without a general knowledge among the people, who have a right

, from the frame. of their nature, to knowledge, as their great Creator, who does nothing in vain, has given them understandings, and a desire to know; but besides this, they have a right, an indisputable, unalienable, indefeasible, divine right to that most dreaded and envied kind of knowledge; I mean, of the characters and conduct of their rulers. Rulers are no more than attorneys, agents, and trustees, for the people; and if the cause, the interest and trust, is insidiously betrayed, or wantonly trifled away, the people have a right to revoke the authority that they themselves have deputed, and to constitute abler and better agents, attorneys, and trustees and the preservation of the means of knowledge among the lowest ranks is of more importance to the public than all the property of all the rich men in the country. It is even of more consequence to the rich themselves, and to their posterity. The only question is whether it is a public emolument: and if it is, the rich ought undoubtedly to contribute, in the same proportion as to all other public burdens—that is, in proportion to their wealth, which is secured by public expenses. But none of the means of information are more sacred, or have been cherished with more tenderness and care by the settlers of America, than the press. Care has been taken that the art of printing should be encouraged, and that it should be easy and cheap and safe for any person to communicate his thoughts to the public.

第10题

Once a circle missed a wedge. The circle wanted to be whole, so it went around looking for

its missing piece. But because it was incomplete and therefore could roll only very slowly, it admired the flowers along the way. It chatted with worms. It enjoyed the sunshine. It found lots of different pieces, but none of them fit. So it left them all by the side of the road and kept on searching. Then one day the circle found a piece that fit perfectly. It was so happy. Now it could be whole, with nothing missing. It incorporated the missing piece into itself and began to roll. Now that it was a perfect circle, it could roll very fast, too fast to notice flowers or talk to the worms. When it realized how different the world seemed when it rolled so quickly, it stopped, left its found piece by the side of the road and rolled slowly away. The lesson of the story, I suggested, was that in some strange sense we are more whole when we are missing something. The man who has everything is in some ways a poor man. He will never know what it feels like to yearn, to hope, to nourish his soul with the dream of something better. He will never know the experience of having someone who loves him give him something he has always wanted or never had. There is a wholeness about the person who has come to terms with his limitations, who has been brave enough to let go of his unrealistic dreams and not feel like a failure for doing so. There is a wholeness about the man or woman who has learned that he or she is strong enough to go through a tragedy and survive, who can lose someone and still feel like a complete person.
