COME, let us go to the smith's shop. What is he doing? He has a forge:he blows the fire with a great pair of bellows, to make the iron hot.
Now he takes it out with the tongs, and puts it upon the anvil. Now he beats it with a hammer. How hard he works! The sparks fly about;pretty bright sparks.
What is the blacksmith making? He is making nails, and horseshoes, and a great many things.
What are nails and horse -shoes made of? They are made of iron. Iron is of great use to us. It is used to make ploughs, wheels, ships, steam -engines, and all kinds of things. We could not do without iron.
Steel is made of iron. Steel is very bright, and sharp, and hard. Knives and scissors are made of steel.
来吧，咱们去铁匠铺！铁匠在干什么呢？铁匠铺有一个熔炉：他用一对大号的风箱把火吹旺，把铁烧得火热。
这时候，他再用钳子把铁块夹出来，放在铁砧上，再用锤子敲。铁匠干活多么卖力啊！明亮的美丽火星儿到处飞舞。
铁匠做的是什么呢？他做的是钉子、马掌，还有好多好多东西。
钉子跟马掌都是什么做的呢？是铁做的。铁对我们的用处可大了。铁能做成犁、车轮子、轮船、蒸汽机，还有各种各样的东西。没有铁，我们可就没法生活了。
“钢”也是铁做的。钢的颜色很明亮，又锋利，又坚硬。刀子、剪子都是钢做的。
