[参考范文]
People's lives will change dramatically in the next 50 years. We anticipate advances in genetics, medicine, and transportation, the opening of international markets, and more. People look enthusiastically to the future, Yet, life today is also dramatically different from life 50 years ago, and that life was dramatically different from life 100 years ago.
Is life "better" now than it was fifty years ago? For many people, the answer is yes. But for many, the answer is no, Hunger, poverty, misery, repression and cruelty existed a hundred years ago. They existed thousands of years ago, and they exist today. "Technology" and "development" have improved life dramatically for great numbers of people. But to some people these benefits are not available, and their existence alone does not address the problems of those people. For ail our "advancement", a large part of our world lives worse, or no better, than it did fifty years ago. A future in which all people could enjoy the fruits of this advancement would be a future truly worth celebrating.
