My answer to this question is :by ear.

   I think, it is important for children to read by ear. As for this one, you shouldthink about how to change      language into your own thing, how to grasp language.It may be clear.

   It is improper to learn how to read without a lot of listening practice. If thechildren is poor in listening practice, it will make a great difference inchildren learning ability, reading ability, thinking ability and concentration.

   It is really important to read stories to children on your own. Instead of lettingthe children to read on their own, the grown-up should read the stories tochildren.

 With the experience of learn the language by ears, the children canlearn how to read and realize the fun on their own.
