“哪里有压迫，哪里就有反抗！”中国人民在共产党的领导下，开展了不屈不挠的八年抗战，许多可歌可泣的英雄故事就发生在这一段峥嵘岁月里。
小兵张嘎，平原游击队的李向阳，抗联的杨靖宇……，这些英雄们都已深深地铭刻在我们的心里。
然而，就是在那一段血雨腥风的日子里，又有多少鲜为人知而又可歌可泣的故事曾经发生啊……在充满诗情画意的芦花荡里，一个干瘦的老头子，整天自如地穿梭着。
他让抗日将士感到快乐，让日本鬼子感到胆寒。
他自信，他自尊；他有柔情，有热血，有仇恨，他是一只勇敢的鱼鹰！他每天夜里出没于芦花荡里，运送粮草，护送干部，从没出过一次事。
可这一天，他护送两个小姑娘去大部队那里，却……欲知后事如何，请同学们随孙犁一起，乘着渔船，划进芦花荡，划到老头子的船边，去看一看，这个生动故事的始末。
并想一想，这个“神奇”的老头子是一个什么样的人呢？参考答案2 芦花荡老头子是一个自尊、自信、善良、正直，很要面子，又有着强烈的爱国主义情感的人。

2.一位魔术师表演魔术，他要当众将一座大楼消失，观众们对他精湛的表演啧啧称奇，其实这个魔术的原理很简单.
假设大楼高30米，观众坐在距大楼500米处，魔术师只需做一个屏障，屏障上的图画和没有大楼后周围景物一样，将屏障立在大楼前100米处，这样，观众看去好像大楼突然消失了.
那么，若要完全挡住大楼，你能找一个方法计算出屏障至少要多高么？。

答：
（2）∠C′是否等于∠C？
答：
（3）由以上你能判定△ABC是直角三角形吗？请你想一想，三角形三条边长满足什么关系，这个三角形一定是直角三角形？
测验评价等级：A B C，我对测验结果（满意、一般、不满意）
参考答案
（1）△A′B′C′≌△ABC
理由：在Rt△A′B′C′中，B′C′=a,A′C′=b,∠C′=90°
由勾股定理得：(A′B′)2=a2+b2
又∵a2+b2=c2,∴(A′B′)2=c2
则A′B′=c=AB
在△ABC和△A′B′C′中，AB=A′B′，BC=B′C′，AC=A′C′，
∴△ABC≌△A′B′C′
（2）由（1）可得∠C′=∠C，又∠C′=90°,所以∠C=90°.
(3)由（2）结论可知△ABC是Rt△.
由以上可得：如果三角形中两边的平方和等于第三边的平方，那么这个三角形一定是直角三角形.。
