【正确答案】 1、正确答案：As time goes by, everything changes in the world. History is indeed the most vivid textbook. War of aggression launched by fascists has brought great scourge to the mankind and enlightened the people throughout the world. People had not only won the war, but also achieved peace and progress. Half a century later, the painful memories, the joy of victory and the deep meditation have made people become more sober-minded. History has proved that peace does not come easily, and the tragedy of a world war should never be allowed to happen again. We must always maintain strong vigilance, develop and strengthen forces of peace, prevent and eliminate all factors leading to war. History has demonstrated that people are, in the end, masters of their destiny and powerful forces promoting social progress. Anything that is just and progressive is bound to win, and cannot be smothered or stopped by any force.
