字数可能有点少
《天火之谜》,主要讲了富兰克林用“风筝实验”来揭开了人们的心目中可怕一雷暴.那么,雷暴到底是什么呢?直到了18世纪才被美国科学家富克兰林解开了这个谜团.
当富兰克林观察到天上的雷暴与静电放电现象.有很多相似之处,因此,他大胆地推测,雷暴就是人们熟知的放电现象.没有人相信他,还对他冷嘲热讽.面对人们的取笑,但是富兰克林的决心并没有因此动摇.
他决定用实验证明.
在做“风筝实验”时,富兰克林用手指靠近铜钥匙,“啪”的一声,骤然闪现一道蓝色的火花,他的手臂一阵发麻.
这两段话分别表现出了富兰克林的决心和勇敢,还写出了富兰克林是一个勇敢无畏敢于献身的人.但如果富兰克林没有决心,没有坚忍不拔的意志心,被人家三言两语一说,心就动摇了.那怎么还可能有“风筝实验”呢?
后来,富兰克林还根据放电的原理,发明了避雷针.
读过这篇文章后,最使我感动的是,富兰克林那不怕危险,敢于献身的精神值得我们学习.

自然是神奇的
