我猜、我学、我用(12-22-04)? 1 你回首看得越远,你向前也会看得越远 2 winston churchill 温斯顿·邱吉尔 3 “v” take fphotos appendix: 1 3000kg 2 winston churchill winston churchill (1874-1965), british leader. english on his father's side, american on his mother's, sir winston churchill embodied and expressed the double vitality and the national qualities of both peoples. churchill took a leading part in laying the foundations of the welfare state in britain, in preparing the royal navy for world war i, and in settling the political boundaries in the middle east after the war. in world war ii emerged as the leader of british nation to resist the german domination of europe, as an inspirer of the resistance among free peoples, and as a prime architect of victory. his dominant qualities were courage and imagination. less obvious to the public, but no less important, was his powerful, original, and fertile intellect. the artistic side of his temperament was displayed in his writings and oratorical style, as well as in his paintings. he was a combination of soldier, writer, artist, and statesman. like julius caesar, he stands out not only as a great man of action, but as a writer of it too. on may 10, 1940, in the midst of disasters, churchill was called to supreme power and he really was chosen by the will of the nation. for the next five years, perhaps the most heroic period in britain's history, he held supreme command, as prime minister and minister of defense, in the nation's war effort. at this point his life and career became one with britain's story and its survival. on oct. 26, 1951, at the age of 77, he again became prime minister. churchill's later years were relatively tranquil. on april 9, 1963, he received, by special act of the u.s. congress, the unprecedented honor of being made an honorary american citizen. when he died in london on jan. 24, 1965, at the age of 90, he was acclaimed as a citizen of the world, and on january 30 he was given the funeral of a hero.查看更多
