B How to make a fire
导读：火是人们生活中必不可少的东西。人类最早是怎样生火的呢？读一读下面的短文,了解一下人类从古到今的生火方式。
Long long ago, people made fires from lightning. But they had to keep the fire burning, for they couldn't start it again if there was no lightning. Later, they found out hitting two pieces of stone together could make a spark. The spark could burn dry leaves. In this way they could make fire again if it went out.
Then people also learned to make a fire by rubbing. They made a hole on a big piece of wood and put a smaller stick into the hole. They turned the stick again and again. After a few minutes they got a fire.
As years went by, people learned other ways to make a fire. Sometimes they used the heat from the sun. They held a piece of glass in the right way and made a piece of paper burn.
About two centuries ago, people began to make matches. Using matches is a quick and easy way to make fires. Today people still use matches, but they have more ways to make fires. One of them is to use an electric fire starter. Of course an electric fire starter is much more expensive than a box of matches, but it is very useful.

### B 如何生火
导读：火是人们生活中必不可少的东西。人类最早是怎样生火的呢？读一读下面的短文，了解一下人类从古到今的生火方式。
很久很久以前，人们靠闪电生火。但他们必须让火一直燃烧着，因为如果没有闪电，他们就无法再次生火。后来，他们发现互相击打两块石头可以产生火花。火花可以点燃干树叶。这样，要是火熄灭了，他们就又能生火了。
然后人们也学会了通过摩擦来生火。他们在一块大木头上钻一个洞，然后把一根小木棍放进洞里。他们一遍又一遍地转动木棍。几分钟后，他们就生起火了。
随着岁月的流逝，人们学会了其他生火的方法。有时他们会利用太阳的热量。他们以正确的方式拿着一块玻璃，就能让一张纸燃烧起来。
大约两个世纪前，人们开始制造火柴。使用火柴是一种快速且简便的生火方式。如今人们仍然使用火柴，但他们有了更多生火的方法。其中一种方法是使用电子点火器。当然，电子点火器比一盒火柴贵得多，但它非常有用。
