锯是怎样发明的

木工用的锯,传说是鲁班发明的。

  有一回,鲁班造一座宫殿,需要很多木料,就叫他的徒弟上山去砍树。当时还没有锯,砍树全靠斧子,一天砍不了几棵。鲁班很着急,就亲自上山去看。

  山很陡,鲁班抓住树根和杂草,一步一步往上爬。他的手指忽然被一棵小草划破了,流出血来。

  一棵小草怎么会这样厉害?鲁班仔细一看,发现小草的叶子边上有许多小齿。他试了试,在手指上一拉就是一道口子。这可提醒了鲁班,他想:如果用铁打一把有齿的工具,在树上来回拉,不是比用斧子砍快得多吗?

他马上回去打了一把,拿到山上去试,果然又快又省力。鲁班就这样发明了锯。


How the Saw Was Invented

According to Chinese legend, the woodcutter's saw was invented by a man named Lu Ban.

A long time ago, Lu Ban wanted to build a palace and needed a lot of wood. He asked his followers to go up to the mountain to cut trees. At that time, there was no saw, so they cut the trees using axes. They were only able to cut a few trees in a single day. Lu Ban was very anxious and went up to the mountain himself to take a look.

The mountain was very steep, so Lu Ban grab onto the grasses and weeds in order to climb up step by step. His fingers were suddenly cut through by a grass, causing it to bleed.

How can a grass be so powerful? Lu Ban took a closer look and found that on the edge of the grass, there were many small teeth. He ran his finger against the edge and immediately there was a cut on the finger. This inspired Lu Ban and he thought: If I were to create a similar tool using iron and pull back and forth against the tree, would it be able to cut the tree much faster than an ax?

He immediately went back create such a tool, went up the mountains to give it a try, and it was really fast and effortless. Thus Lu Ban had invented the saw.
