法国皇帝拿破仑行伍出身,当过炮兵军官,他对射击和测量中用到的几何和三角形知识有所接触.随着兴趣增加,理论的提高,拿破仑对几何学的研究达到了很深的造诣,他曾经给后人留下了脍炙人口的“拿破仑三角形”.拿破仑三角形指的是在一个三角形三边外侧,分别作三个等边三角形,以他们的中心为顶点所构成的三角形,称为外拿破仑三角形;若在一个三角形三边内侧,分别作三个等边三角形,以他们的中心为顶点所构成的三角形,称为内拿破仑三角形.拿破仑证明了在今天也并非容易的事实——这两个三角形都是等边三角形.同学们,请你根据上面的描述画出一个外拿破仑三角形或一个内拿破仑三角形.

1709年,当时的普鲁士国王为了效仿法国皇帝路易十四的奢华生活,命令普鲁士最有名的建筑师兴建“琥珀屋”,建成后光彩夺目、富丽堂皇,被誉为“世界第八奇迹”.在第二次世界大战中,“琥珀屋”被冲进圣彼得堡的纳粹劫走,然而随着二战的结束,这一旷世宝藏突然从世人眼中失去了踪影.近些年来,越来越多的人相信,27箱被拆整为零的“琥珀屋”,可能正沉在奥地利的一个湖底!

The person I admire most is Napoleon Bonaparte. Because of his indomitable spirit is worthy of my learning, Napoleon Bonaparte a great emperor of France to his outstanding military leadership. It is because of his outstanding leadership which he proclaimed himself Emperor in a few years. He once said: the glory of life, is not solely, but can be repeated from repeated head. As long as there is a breath in the will to stand up in their own fall.
