英语阅读理解Do you know why schools first started?
Do you know why schools first started?Well,it was like this.From the earliest days man lived in groups.Each group had its own customs(风俗习惯) and traditions(传统).The people of the group wanted their children to live in the same way and to follow the same customs and traditions.At first the older members of the group taught the younger members everything they knew.This was a kind of “education” which happened long before schools existed(存在).
But then they invented letters and learned how to write.After that schools became necessary because it isn’t easy to teach children how to write.It is a specialized job（专门的 工作）.So schools started with specialized teachers to work in them.
Nobody knows when the first schools appeared(出现).But we do know that there were schools in Egypt(埃及) and perhaps in China (and maybe in other countries) about five or six thousand years ago.
Schools like the schools we have today started in the eighteenth century.And it was only a little more than a hundred years ago that people realized(认识到) that a good education was the right of every child.That’s why all children go to school today!
