The importance of reading and writing
Human beings invented languages to communicate with each other.Today, each standard language consists of four skills : Reading, Listening, Speaking and Writing.

Speaking and listening have existed since the invention of human languages; but, writing and reading are not more than 10000 years old.

According to what I believe writing was invented to keep we say(speaking).The better you speak, the more influence your writing will have and the better you listen , the more complete you understand a text.

In the past, few books were published as there were no printing tools.One had to write a book completely by hand.Readng and writing were not so important.

Today many books are printed and published and the number of bookworms is increasing, day in day out.So we need reading and writing more than in the past.

please tell me my mistakes(punctuation, gramatical, spelling).
Thanks in advance.
